The COVID-19 lockdown reshaped lives in many ways, including how people approached pet ownership. During the pandemic, a surge in puppy purchases swept across the U.K. as individuals and families sought companionship while they were confined to their homes.



While many welcomed new furry companions with open arms, concerns arose about the long-term consequences of these impulsive adoptions.



Would owners remain committed once life returned to normal? Would these dogs develop behavioral problems due to rushed decisions and inadequate training? Researchers at The Royal Veterinary College (<a href="https://www.rvc.ac.uk" target="_blank" rel="noreferrer noopener">RVC</a>), U.K., led by Dr. Bree Merritt, set out to answer these questions.



The study, published in the journal PLOS One, reveals the complex reality of pandemic <a href="https://www.earth.com/news/reimagining-pet-diets-for-a-more-sustainable-future/" target="_blank" rel="noreferrer noopener">puppy ownership</a>.



<h2 class="wp-block-heading" id="h-puppy-purchases-during-the-pandemic">Puppy purchases during the pandemic</h2>



As lockdown measures took hold in early 2020, people found themselves spending more time at home. Many saw this as the perfect opportunity to welcome a <a href="https://www.earth.com/news/national-dog-day-honoring-mans-best-friend/" target="_blank" rel="noreferrer noopener">puppy</a> into their lives.



The demand for dogs soared, leading to inflated prices, overwhelmed breeders, and, in some cases, unethical breeding practices.



Animal welfare experts expressed concerns about the potential fallout. They worried that some buyers acted impulsively, without considering whether they could provide for a dog long-term. Would these pandemic puppies face neglect, abandonment, or behavioral struggles in homes that were unprepared for their needs? 



These questions fueled the need for deeper research into the experiences of owners and their dogs.



<h2 class="wp-block-heading" id="h-tracking-pandemic-puppy-owners">Tracking pandemic puppy owners</h2>



To better understand the reality of pandemic <a href="https://www.earth.com/news/dog-owners-ages-and-beliefs-influence-their-pet-food-choices/" target="_blank" rel="noreferrer noopener">puppy ownership</a>, the researchers surveyed nearly 800 U.K. dog owners who had purchased a puppy between March and December 2020. The study aimed to uncover their motivations, training approaches, and overall experiences.



Participants provided details about their daily interactions with their pets, their emotional connection, and any difficulties they faced. A follow-up survey was conducted when the puppies reached 21 months of age. 



This allowed researchers to assess how ownership experiences evolved over time and whether the initial excitement had given way to unexpected challenges.



<h2 class="wp-block-heading" id="h-owners-stayed-committed-but-at-a-cost">Owners stayed committed, but at a cost</h2>



Despite widespread concerns that many pandemic puppies would end up abandoned or rehomed, the study found that 98% of surveyed owners still had their dogs at 21 months old. 



This high retention rate suggests that, for most, the commitment to their pets remained strong even as their daily routines returned to normal.



However, the study also revealed that ownership came with significant challenges. Of those surveyed, 40% admitted that the pandemic influenced their decision to get a <a href="https://www.earth.com/news/how-dogs-say-goodbye-before-they-die-these-signs-will-tell-you-if-your-friend-is-leaving-soon/" target="_blank" rel="noreferrer noopener">dog</a>.



These owners were more likely to report difficulties related to costs, lifestyle changes, and unexpected responsibilities. Many struggled with cleaning up after their pets, sacrificing personal activities, and managing expenses.



<h2 class="wp-block-heading" id="h-behavioral-issues-and-owner-burden">Behavioral issues and owner burden</h2>



One of the biggest concerns for pandemic puppy owners was behavioral issues. 



Dogs that grew up in lockdown often had limited exposure to the outside world, leading to problems such as separation anxiety, control struggles, and aggression. Owners who reported behavioral difficulties felt a greater burden of dog ownership.



While various problem behaviors caused stress, aggression had the most significant impact. Owners of aggressive dogs experienced a weaker emotional connection with their pets compared to those dealing with other challenges. 



This highlights the importance of early intervention and training to prevent behavioral issues from escalating.



<h2 class="wp-block-heading" id="h-capturing-the-whole-picture">Capturing the whole picture</h2>



The study acknowledged a potential limitation in its findings. Owners who had already rehomed their dogs might have been less likely to participate in the follow-up survey. 



This means the 98% retention rate could represent a best-case scenario. Some dogs may have been relinquished after the survey period ended, making the overall picture more complex than the data suggests.



Additionally, the financial and emotional burdens of dog ownership might have driven some participants to keep their struggles private. Many may have hesitated to admit difficulties, especially if they felt judged for their decision to acquire a dog during the pandemic.



<h2 class="wp-block-heading" id="h-need-for-better-behavioral-support">Need for better behavioral support</h2>



For those who faced challenges with their pandemic puppies, access to evidence-based behavioral support could make a crucial difference. Professional training and behavior modification techniques could help struggling owners manage their dogs more effectively, improving their overall quality of life.



"Relationships with our dogs can be immensely rewarding, but it’s not all fun and games. Looking after them can be hard work, expensive or even change day-to-day activities," noted Dr. Merritt.



"Problem behaviors are likely to be a much wider concern beyond just those dogs who were brought home during the pandemic. These results show how important it is to find evidence-based help for problem behavior to improve the emotional health of <a href="https://www.earth.com/news/friends-family-members-and-guardians-dogs-are-more-than-just-pets/" target="_blank" rel="noreferrer noopener">dogs</a>, their owners and sustain their relationship.”



<h2 class="wp-block-heading" id="h-impulsive-pandemic-puppy-purchases">Impulsive pandemic puppy purchases</h2>



The findings of this study serve as an important reminder that dog ownership requires long-term planning, not just short-term enthusiasm. 



Many pandemic puppy buyers made decisions based on the temporary circumstances of lockdown life. Once restrictions eased and daily routines resumed, they found themselves struggling with responsibilities they had not fully anticipated.



"Impulsive acquisition of dogs based on short-term circumstances is an enduring challenge for the canine welfare sector," said Dr. Rowena Packer, senior author of the study. 



"Here, we demonstrate that puppy purchases that were a direct result of the COVID-19 pandemic, such as having increased time for a dog during this atypical period, resulted in owners who felt a greater burden of dog ownership by the time their puppy was a young adult, compared to owners whose purchases were planned based on longer-term circumstances."



"U.K. campaigns have long encouraged owners to consider their ability to care for a dog for the duration of its lifetime at acquisition. However, if the efficacy of these messages remains limited, greater interventions may be needed to emphasize the responsibilities of dog ownership, ideally prior to purchase.”



<h2 class="wp-block-heading" id="h-a-lifelong-commitment">A lifelong commitment</h2>



While most pandemic puppy owners chose to keep their dogs, the challenges they faced highlight the importance of informed decision-making. 



Owning a dog is not just about companionship; it requires time, effort, and financial resources. Without proper preparation, owners can find themselves overwhelmed, and their pets may suffer as a result.



The study reinforces the need for education and support for prospective dog owners. Those considering bringing a pet into their home must evaluate their long-term ability to care for an animal - not just their immediate desire for companionship.



With the right guidance, future pet buyers can ensure a fulfilling and responsible relationship with their dogs, built on commitment rather than impulse.



The study is published in the journal <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0316166" target="_blank" rel="noreferrer noopener">PLOS One</a>.

Pandemic puppy owners report challenges but remain committed

The COVID-19 lockdown reshaped lives in many ways, including how people approached pet ownership. During the pandemic, a surge in puppy purchases swept across the U.K. as individuals and families sought companionship while they were confined to their homes. While many welcomed new furry companions with open arms, concerns arose about the long-term consequences of these impulsive adoptions. Would owners remain committed once life returned to normal?

In the past, there was some belief among scientists and the general public that frequent marijuana use may decrease an individual’s sexual desire or performance. Now, a new study published in the <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1743-6109">Journal of Sexual Medicine</a> has found strong evidence that the effect of marijuana use might actually be the opposite.

“Frequent marijuana use doesn’t seem to impair sexual motivation or performance. If anything, it’s associated with increased coital frequency,” says Dr. Michael Eisenberg, the study's senior author and assistant professor of urology at <a href="http://med.stanford.edu/">Stanford University</a>.

According to the National Institute on Drug Abuse, over 20 million adult Americans currently use marijuana, and with the legalization of <a href="https://www.earth.com/news/cannabis-sleep-users/">cannabis</a> for medical or recreational use in 29 states, that number is only getting higher (no pun intended).

This study was the first to examine the relationship between cannabis use and frequency of sexual intercourse at the population level in the U.S., surveying over 50,000 men and women, ages 25-45. The researchers used the National Survey of Family Growth, which provides data related to family structures, sexual practices, and child bearing.

They found that 24.5 percent of men and 14.5 percent of women reported using marijuana in the previous four weeks, and there was a strong correlation between increased marijuana use and increased sexual intercourse in that time period. In fact, cannabis users reported having roughly 20 percent more sex than non-users.

"The overall trend we saw applied to people of both sexes and all races, ages, education levels, income groups and religions, every health status, whether they were married or single and whether or not they had kids,” Eisenberg adds. Furthermore, this was still the case when the researchers accounted for other substance use, which shows that this correlation isn’t necessarily due to these individuals simply being less inhibited.

Although a significant correlation was found between increased marijuana usage and sexual activity, it doesn’t mean that this study established a causal link. In other words, Eisenberg cautions, “it doesn't say if you smoke more marijuana, you’ll have more sex.” So you should probably put down your car keys and go back to sitting on the couch – the pot shop can wait.

Study finds that more marijuana use means more sex

How great are dogs? It’s hard to find someone who doesn’t love them, or at least appreciate the role of the dog in our daily lives. There are so many reasons to enjoy their existence, and scientists may have just found a couple more.

Two studies presented at the American College of Allergy, Asthma, and Immunology (ACAAI) Annual Scientific Meeting found that the presence of a dog in a child’s home may help protect them against eczema and asthma.

One study found that babies born in a home with a <a href="https://www.earth.com/news/dogs-expressive-looking/">dog</a> during pregnancy get the benefit of added protection from allergic eczema. “Although eczema is commonly found in infants, many people don’t know there is a progression from eczema to food allergies to nasal allergies and asthma,” says Dr. Gagandeep Cheema, an allergist and lead author of the study. “We wanted to know if there was a protective effect in having a dog that slowed down that progress.”

Through examining mother-child pairs that were exposed to a dog before birth, the researchers found that this exposure is associated with a lower risk of eczema by the time the child is 2-years-old. However, this protective effect goes down at the age of 10.

For the second study, researchers analyzed the effects of two separate types of dog exposure to children with asthma in Baltimore, MD. The first type was a protein, or allergen, that affects children who are allergic to dogs. The second type were elements that the dog might carry, such as bacteria. Ultimately, the results showed that exposure to elements that a dog may carry could have protective effects against asthma symptoms for the child. However, exposure to the allergen protein may increase asthma symptoms among urban children with a dog allergy.

“Among urban children with asthma who were allergic to dogs, spending time with a dog might be associated with two different effects,” says Dr. Po-Yang Tsou, the lead author of the study. “There seems to be a protective effect on asthma of non-allergen dog-associated exposures, and a harmful effect of allergen exposure.”

Both of these studies show that there seem to be even more benefits to living with dogs than we even imagined – it almost seems too good to be true.

It has become increasingly popular for people to keep exotic pets such as reptiles and amphibians. But this can pose many problems for ill-equipped owners who don’t know how to care for them properly.

There are also health and safety concerns regarding the trade of exotic animals, which has led some to argue for increased restrictions for pet reptiles and amphibians. 

Veterinary Record has published a collection of articles reviewing the arguments both for and against keeping these kinds of pets. 

One article written by a team of researchers from <a href="https://www.ugent.be/en">Ghent University</a> argues that reptiles and amphibians are no more cause for concern than any other pet. The researchers note that it’s the responsibility of the <a href="https://www.earth.com/news/easiest-pets-care/">pet owner</a> to research and make sure they have everything they need to properly care of their animal. 

The team also discusses diseases that can be transmitted to humans and the issues with the illegal trade in wild animals, but with proper care and the right information, there is no problem with keeping lizards and frogs in your home.

They also suggest possible measures that will minimize any risks to the health and wellbeing of both the pet and its owner, including introducing minimal care requirements and improving access to specialist veterinarians. 

Gordon Burghardt from the<a href="https://www.utk.edu/"> University of Tennessee </a>agrees with these general principles and also feels that keeping amphibians and reptiles as pets isn’t a major problem. 

Amphibians and reptiles “are compatible with modern lifestyles,” said Burghardt. 

However, there are those who feel that certain reptiles and amphibians should not be kept as pets. 

75 percent of reptiles die during their first year in the home according to Clifford Warwick, a consultant biologist and medical scientist from the United Kingdom. 

Warwick and colleagues also argue that the five aspects of animal welfare under human control, something set in motion by the Farm Animal Welfare Council in 1979, are impossible to meet for reptiles and amphibians 

“There is growing concern about the welfare of reptiles. Earlier this month the RSPCA [Royal Society for the Prevention of Cruelty to Animals] published research showing they are often neglected, and not because their owners don't care about them, but because they are unsure about how to care for them,” said Adele Waters, editor of Veterinary Record. 

Ultimately, it appears to come down to adequate preparation for keeping the animals.

“Research conducted for the charity found a lot of online advice is contradictory, inconsistent and variable in quality and this does not encourage responsible reptile ownership. It is important for reptile owners to get information from a reliable, credible source - their local vet,” said Waters.

A revealing new study has found that almost half of adults with food allergies developed one or more of these allergies during adulthood. Since allergies are typically associated with <a href="https://www.earth.com/news/children-practicing-age-6/">children</a>, this is an unexpected discovery.

"Food allergies are often seen as a condition that begins in childhood, so the idea that 45 percent of adults with food allergies develop them in adulthood is surprising," said lead author Ruchi Gupta. "We also saw that, as with children, the incidence of food allergies in adults is rising across all ethnic groups."

Shellfish is the most common allergy among adults, affecting around 3.6 percent of adults in the United States. This estimate is 44 percent higher than the 2.5 percent rate which was determined in a 2004 study. The findings of the current analysis demonstrate that tree nut allergies are also on the rise in American adults, increasing by 260 percent since 2008.

"Our research also found that, among black, Asian and Hispanic adults, the risk of developing a food allergy to certain foods is higher than for whites, specifically for shellfish and peanuts," said co-author Christopher Warren. "For example, Asian adults were 2.1 times more likely to report a shellfish allergy than white adults, and Hispanic adults reported a peanut allergy at 2.3 times the frequency of white adults.” 

Adults most likely consider an adverse reaction to food as simply a food intolerance, potentially causing a food allergy to go undiagnosed. Allergists are trained to perform allergy testing and can customize a personal treatment plan upon diagnosis. 

“Because many adults believe food allergies mostly affect children, they may not think to get tested,” said Warren. “It is important to see an allergist for testing and diagnosis if you are having a reaction to a food and suspect a food allergy."

The research is being presented at the <a href="http://acaai.org/">American College of Allergy, Asthma and Immunology </a>(ACAAI) Annual Scientific Meeting which takes place this month in Boston, Massachusetts.

It is projected that by the year 2050, there will be an additional 25 million kilometers of new paved roads all around the globe. That’s enough roadways to circle the planet over 600 times. In Asia’s developing countries alone, paved roads are expected to double in length.

Why is this important? According to a new study led by William Laurance of <a href="https://www.jcu.edu.au/">James Cook University</a>, this global uptick of new roads comes with a plethora of economic, social, and environmental dangers.

“We’ve scrutinized major roads and infrastructure projects around the world,” said Laurance, “and it’s remarkable how many have serious hidden costs and risks.”

Co-authored by Irene Burgués Arrea, an economist who has studied road-building costs and benefits in Latin America and Africa, the study was published in the journal Science. The researchers say that the most urgent priority is limiting millions of kilometers of new roads that are being planned or already being built in high-rainfall areas. This is mostly occurring in developing nations in Asia, <a href="https://www.earth.com/news/climate-change-humans-africa/">Africa</a>, and Latin America. 

“This is where ambition for quick profits meets nearly impossible engineering,” says Laurance. “Rainfall-drenched roads develop pot-holes, giant cracks and landslides so fast it’s nearly unbelievable. They can quickly turn into giant money-losers."

Burgués Arrea also adds that adding in the environmental and social costs of building these roads, it’s clear that there is very little upside to their construction. 

“The public often ends up with major debts from failed roads. A few road developers and politicians get rich, but vital development opportunities are easily squandered,” explains Laurance. “It’s remarkable how many nations, investors, and lenders are failing to see the profound risks of road expansion in wet tropical environments, which are also the world’s biologically richest ecosystems.”

In the state of California, as many as 10,000 children under six years old are poisoned by lead each year. An investigation by researchers from the <a href="https://www.ucsf.edu/">University of California San Francisco</a> have found that much of this lead contamination is found in an unexpected source - imported candy.

In 2006, the state passed a law which required the California Department of Public Health (CDPH) to test candy for lead and issue alerts when levels get high. The experts from UC San Francisco joined up with researchers at the CDPH to analyze the outcomes of the law, which was proposed following several high-profile poisoning cases.

The CDPH issued more alerts for lead in candy than for the top three sources of food combination combined in the years that followed the new legislation. While the CDPH had routinely tested food for contaminants and warned the public of toxic exposure before this law was passed, lead levels in candy were not assessed on a regular basis.

The new study revealed that in the six years before the law went into effect, only 22 percent of the alerts about food contamination involved lead in candy. Once the testing was mandated by law, however, 42 percent of the food contamination alerts issued by state health officials were for lead in candy, nearly all of which was imported.

Lead is a toxic metal that can cause developmental delays, neurological damage, and other serious health problems. The researchers determined that active community monitoring can identify lead in food products such as candy, which can help them to be recalled before too many people have eaten them.

"With this policy change identifying lead sources is more upstream and community-based," said first author Margaret Handley. "By testing candy and issuing alerts when foods are found to be contaminated, we can identify and remove sources of lead before children become poisoned."

Over the 14-year time frame examined by the researchers, public health officials issued 164 health alerts for food contamination in California. 60 of these were lead-related and 55 of those were for imported food, mostly candy from Mexico, <a href="https://www.earth.com/news/pollution-chinas-solar-energy/">China</a>, and India. 

"As more lead sources are identified we must develop prevention approaches for all of them, and not just replace one prevention approach with another," said Handley. "If there is anything we have learned from the lead poisoning disaster in Flint, Michigan, it is not to oversimplify or cut corners when it comes to identifying and removing sources of lead poisoning."

The study is published in the journal <a href="https://ehp.niehs.nih.gov/">Environmental Health Perspectives</a>.

A new study confirms that the arched back of a woman is attractive to men. 3D imaging and eye-tracking technology provide scientific evidence that slight changes to the angle of a woman's body, such as the arching of the back, can captivate both a male and female audience.

The research team was led by Farid Pazhoohi of the <a href="https://www.uminho.pt/EN">University of Minho</a>. Pazhoohi explained that this particular posture may have evolved as part of the mating behavior of humans. Previous studies of animals such as sheep, cats, and primates have shown that this posture in which the lower spine is curved towards the belly, or lordotic posture, can signal readiness to mate.

The researchers set out to investigate the role of body posture in the development of human mate attraction and selection. For their study, the experts generated 3D computer models of the upper bodies of six women. The backs were positioned at slightly different yet natural body angles, which caused variations in how the backs were arched and the buttocks were extended.

Views from the front, side, and the back of each of the models were presented to 82 male and female participants. The individuals, who were all undergraduate students, were asked to rate how attractive they found each posture. Eye-tracking technology was used to monitor what the students were specifically looking at as they examined the images.

The results of the study showed that even the smallest changes in the angle of the back influenced how attractive others perceived the women to be. As the backs was arched slightly more, the 3D models were rated as being more appealing by both male and female participants.

"Increased curvature increases the perception of attractiveness," said Pazhoohi.

The eye tracking provided evidence that the students, regardless of their gender, gazed at the rear view of the simulated women much longer than the side or front angles. The <a href="https://www.earth.com/news/modern-couples-women-house/">female</a> participants focused more on the waist area, while the men looked longer at the hips. 

In addition, both the attractiveness ratings and eye tracking data indicated that the mesmerizing effect is stronger from side and rear views compared to the front, which is where the hips are most easily viewed.

"The latter highlights the unique influence of an arched back on the perception of attractiveness," explained Pazhoohi. "The perception of attractiveness and visual attention to the hip region suggests that lordosis or the arching of the back might signal human females' proceptivity or willingness to be courted. This also might explain why women wear high heel shoes and why wearing high heel shoes increases womens' attractiveness."

The findings are published in Springer's journal <a href="http://www.springer.com/psychology/personality+%26+social+psychology/journal/40806">Evolutionary Psychological Science</a>.

According to a new study, teenagers now are less likely to abuse drugs and alcohol, smoke, or engage in criminal activities like stealing and fighting. 

The study was conducted by researchers at the <a href="https://medicine.wustl.edu/">Washington University School of Medicine</a> in St. Louis, who analyzed years of data from the annual National Survey on Drug Use and Health, a survey of 12 to 17 year-olds from every state in the US. 

The researchers examined data from 2003 to 2014 which included information on 210,599 <a href="https://www.earth.com/news/acknowledging-opinions-teens/">teens</a> in total. 

The study was published in the journal Psychological Medicine and shows a definite drop in substance use and participation in delinquent behaviors. 

The researchers discovered that substance abuse disorders among teens dropped 49 percent over the past 12 years, and delinquent behaviors like fighting, stealing, and selling drugs declined 39 percent. 

Substance abuse disorders are declining in teenagers despite increases in opioid addiction in adults.

Despite the severe opioid epidemic amongst adults, in the 12 to 17 year age bracket opioid use has dropped almost 50 percent.  

The researchers estimate that there were almost 700,000 fewer adolescents with substance abuse disorders in later years compared to 2003. 

An interesting result of the study is how both substance abuse and criminal activities are connected considering their similar patterns of decline. 

“What we learned in this study is that the declines in substance abuse are connected to declines in delinquency,” said Richard Grucza, the study’s first author and a professor of Psychiatry. “This suggests the changes have been driven more by changes in adolescents themselves more than by policies to reduce substance abuse or delinquent behavior.” 

The researchers suggest that higher cigarette taxes and new anti-bullying policies may have contributed to the decline in both substance abuse and delinquent behaviors, but other factors could be having a positive effect as well. 

“Seeing these trends across multiple behaviors suggests that larger environmental factors are at work. These might include reductions in childhood lead exposure, lower rates of child abuse and neglect, and better mental health care for children,” said Grucza.

There is no better time than the present to modify your daily activities and make them more environmentally responsible, and choosing <a href="https://www.earth.com/news/11-eco-friendly-celebrities/">eco-friendly</a> office supplies is a great place to begin. To start greening your office, simply make a list of all the supplies used and research earth-friendly alternatives.

If transforming the entire office is not in your budget, consider switching out one or two items at a time. The following are some of the best environmentally friendly supplies available to help reduce your office's carbon footprint.

Recycled Paper Products

From envelopes to compostable paper cups and plates, recycled paper products now come in many forms. A green transition in this department will have a particularly positive impact considering how frequently paper products are used in the office.

Eco-Friendly Pens

Adopting biodegradable pens made from renewable material is a great way to make your office more green. You may even print your company logo on eco-friendly pens to give potential customers a great first impression.

Where to buy: <a href="http://eco-pens.com/">eco-pens.com</a>

Non-Toxic Cleaner

Why introduce formaldehyde and other harmful chemicals into the air if you don't have to? There are plenty of green products available to clean all of the surfaces in your office while keeping the air quality up to a good standard.

Where to buy: <a href="https://www.seventhgeneration.com/">seventhgeneration.com</a>

Compostable Trash Bags

Disposing of non-biodegradable trash bags week after week just adds to our enormous waste problem. When you think about it, trash bags made of post-consumer recycled (PCR) material just make good environmental sense.

Where to buy: <a href="http://evolutionbags.com/">evolutionbags.com</a>

Solar USB Chargers

The time has arrived when you can easily charge all of your office's USB devices with solar power. This is an inexpensive green transition that every office should make to save energy, particularly for charging devices that are constantly plugged up while not in use.

When rinsing off an apple to eat, it may not occur to you that this fruit is most likely contaminated with pesticide residue. A new discovery by scientists found that baking soda, an item commonly found in homes, effectively reduces the pesticide remains found on fruit.

The United States Department of Agriculture (USDA) found 47 different pesticides on apples tested for the <a href="https://www.ams.usda.gov/datasets/pdp">Pesticide Data Program</a>. While pesticides are helpful in improving crop yields, concerns have been growing over their potentially harmful impact on human health.

It is standard practice in the food industry to wash fruit with running water, but some of the plant-protecting compounds that get absorbed by <a href="https://www.earth.com/news/best-diet-longer-life/">fruits</a> and vegetables may not be removed by tap water. A research team led by Lili He set out to identify a washing strategy that can successfully eliminate contamination found on produce.

The researchers applied two common pesticides, the fungicide thiabendazole and the insecticide phosmet, to organic apples. They then washed the apples with tap water, a baking soda/water solution, and a U.S.-EPA-approved commercial bleach solution. 

The study revealed that the baking soda solution removed the most of the two pesticides from the apples. The water and the bleach solution proved to be much less effective in reducing the contaminants.

After 12 minutes of washing the apples with the baking soda solution, 80 percent of the thiabendazole was removed and 96 percent of the phosmet was removed after 15 minutes. 

Because thiabendazole is absorbed more into the apple, it may not be as easy to remove. 

Images showed that thiabendazole had penetrated up to 80 micrometers deep into the apples, while phosmet only reached a depth of 20 micrometers. 

The findings of the study are published in the <a href="https://www.acs.org/">American Chemical Society</a>'s <a href="http://pubs.acs.org/journal/jafcau">Journal of Agricultural and Food Chemistry</a>.

The global demand for <a href="https://www.earth.com/news/palm-oil-plantations-tropical-butterflies/">palm oil</a> has resulted in the clearing of large areas of forest in Indonesia. Researchers have found that these changes in land use are causing temperatures to get warmer. The additional heat is not only a threat to plants and animals but could also make the region more susceptible to wildfires.

Palm oil is the most widely consumed vegetable oil on the planet. As the world's largest producer of palm oil, Indonesia has replaced vast areas of rainforest with oil palm plantations. Sumatra has the highest loss of rainforest in the country, and the changes in land use have led to a substantial loss of biodiversity on the island. 

An international team of researchers led by Alexander Knohl and Clifton Sabajo of the <a href="http://www.uni-goettingen.de/en/1.html">University of Gottingen</a> conducted the first-ever analysis to examine the impact that these land-use modifications have on Indonesia's temperatures. The results of their study, which was focused on the Jambi province in Sumatra, showed that the expansion of cash crops has made temperatures rise significantly.

"Land use change from forest to cash crops such as oil palm and rubber plantations does not only impact biodiversity and stored carbon, but also has a surface warming effect, adding to climate change," said Knohl.

The team compared the surface temperatures associated with various types of land cover such as forests, clear-cut land, and cash crops in Sumatra. They used satellite data collected between 2000 and 2015 by NASA, as well as data collected on the ground.

The researchers established that clear-cut land, which is primarily used for agriculture, was up to 10 degrees Celsius warmer than forests. Mature palm oil plantations were 0.8 degrees Celsius warmer than forests, while young palm oil plantations were found to be 6 degrees Celsius warmer. 

"Young palm oil plantations have fewer and smaller leaves and an open canopy, thus they transpire less water. Also, the soil receives more solar radiation and dries out faster," explained Sabajo.

Overall, the average surface temperature in the Jambi province increased by 1.05 degrees Celsius between 2000 and 2015. Some of this warming can be attributed to climate change, but some of it is a direct result of the changes in land use.

Knohl pointed out that "land surface temperature is an important part of the microclimate, which shapes habitat conditions for plants and animals." The authors of the study also warned that this spike in temperatures will lessen the amount of water available over the dry season and make the area more vulnerable to wildfires.

"We think that current land-use developments in Indonesia need to carefully evaluate all aspects of environmental and socio-economic consequences. Land-surface temperature and microclimate should be considered," said Knohl.

The study is published in the <a href="https://www.egu.eu/publications/open-access-journals/">European Geosciences Union journal</a>.

Extreme weather events attributed to climate change have cost the United States federal government over $350 billion over the past decade to provide disaster relief and insurance, according to a new report from the <a href="https://www.gao.gov/assets/690/687465.pdf">U.S Government Accountability Office</a> (GAO). 

The report comes at the same time that Congress is working to approve funding for <a href="https://www.earth.com/news/americans-climate-change-hurricanes/">hurricane relief</a> after the string of historic hurricanes that hit Texas, Florida, and the Caribbean. 

"Climate change impacts are already costing the federal government money, and these costs will likely increase over time as the climate continues to change," the report said.

Senators Susan Collins from Maine and Maria Cantwell from Washington asked the GAO to conduct a full report on the cost of climate change. 

The report proves that not only will unmitigated changing climate have disastrous effects on our towns cities, but will also be extremely costly to taxpayers as well. 

The GAO was asked specifically to look at the economic impact of climate change and how it would affect the federal government. The report outlines the methods used to estimate the costs of climate change and recommendations for reducing these costs. 

The report includes reviews of 30 studies on climate change and interviews with 26 experts including researchers, agency officials, and consultants selected specifically by the GAO.

Two of the studies had “national-scale information about the economic effects of climate change across multiple sectors and regions in the United States,” according to the report. 

Those two studies in particular show that the costs of climate change will differ from region to region, with some coastal areas facing damages between 4 and 6 billion dollars per year due to storm surges and potential sea level rise. 

"We cannot ignore the impact of climate change," Senator Collins said in a statement. "This nonpartisan GAO report Senator Cantwell and I requested contains astonishing numbers about the consequences of climate change for our economy and for the federal budget in particular."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes why satellite images and measurements of our planet have become "essential to our survival, offering a new outlook of our world."&nbsp;



Rising sea levels pose one of the biggest societal threats associated with climate change. According to ESA, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.



"Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage," reports ESA.



"Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch."



Dr. Craig Donlon explains that, by understanding planet Earth through satellite measurements, we are able to find evidence of change.&nbsp;
