<p>Today's <strong>Image of the Day</strong> from the European Space Agency features the star-forming region NGC 604, which is located 2.73 million light-years away from Earth in the Triangulum Galaxy (M33). The image was captured by the James Webb Space Telescope.</p>



<p>By studying regions like NGC 604, astronomers can gain insights into the complex interactions between stars and the interstellar medium, as well as the conditions that lead to the birth of stars. This, in turn, helps in understanding the evolution of <a href="https://www.earth.com/news/galaxies-like-our-own-milky-way-are-not-unique/" target="_blank" rel="noreferrer noopener">galaxies</a> and the universe as a whole.</p>



<h2 class="wp-block-heading" id="h-massive-stars-of-ngc-604">Massive stars of NGC 604</h2>



<p>"Sheltered among NGC 604’s dusty envelopes of gas are more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives," said <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a>.</p>



<p>"These types of stars are known as B-types and O-types, the latter of which can be more than 100 times the mass of our own Sun. It’s quite rare to find this concentration of them in the nearby universe. In fact, there’s no similar region within our own Milky Way galaxy."</p>



<p>According to ESA, this concentration of massive stars, combined with its relatively close distance, means NGC 604 gives astronomers an opportunity to study these objects at a fascinating time early in their life.</p>



<h2 class="wp-block-heading" id="h-gigantic-region-of-ionized-hydrogen">Gigantic region of ionized hydrogen</h2>



<p>NGC 604 is one of the largest known regions of ionized hydrogen, also known as an H II region. This nebula is significantly larger than the Orion Nebula, which is one of the most well-known H II regions in our own <a href="https://www.earth.com/news/large-amount-of-dark-matter-may-be-missing-from-the-milky-way/" target="_blank" rel="noreferrer noopener">Milky Way galaxy</a>.&nbsp;</p>



<p>NGC 604 spans about 1,500 light-years across, making it one of the largest H II regions in the Local Group of galaxies. This group includes the Milky Way, the Andromeda Galaxy, and about 54 other smaller galaxies. </p>



<h2 class="wp-block-heading" id="h-ngc-604-starburst-phenomenon">NGC 604 starburst phenomenon </h2>



<p>Within NGC 604, there are hundreds of young, hot, massive <a href="https://www.earth.com/news/stars-at-the-edge-of-our-milky-way-galaxy-travel-more-slowly/" target="_blank" rel="noreferrer noopener">stars</a>. These stars have ionized the surrounding gas, causing it to glow and creating the nebula. The region is a prime example of a starburst phenomenon, where stars form at a much higher rate than in typical galactic conditions.</p>



<p>“The bright orange streaks in this image signify the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons, or PAHs," explained ESA.</p>



<p>"As you travel further from the immediate cavities of dust where the star is forming, the deeper red signifies molecular hydrogen. This cooler gas is a prime environment for star formation. Ionized hydrogen from ultraviolet radiation appears as a white and blue ghostly glow."</p>



<h2 class="wp-block-heading" id="h-more-about-star-formation">More about star formation </h2>



<p>Star formation is crucial for the evolution of galaxies and the synthesis of heavy elements. In the cores of stars, elements heavier than helium are created.</p>



<p>The elements are spread throughout the <a href="https://www.earth.com/news/ancient-stars-shakti-shiva-shaped-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">galaxy</a> when stars reach the end of their lives and expel their material - either gently through winds or violently via supernova explosions. This enriching process allows for the formation of new stars and planets, and ultimately, the potential for life.</p>



<h3 class="wp-block-heading">Cloud collapse</h3>



<p>The process begins when part of a molecular cloud becomes unstable and starts to collapse under its own gravity. This can be triggered by events like shock waves from nearby <a href="https://www.earth.com/news/supernova-explosions-could-damage-distant-planets/" target="_blank" rel="noreferrer noopener">supernovae</a>, galactic collisions, or the influence of other massive stars.</p>



<h3 class="wp-block-heading">Formation of a protostar</h3>



<p>As the cloud collapses, it fragments into smaller clumps. Each clump will eventually form one or more stars. </p>



<p>The material within these clumps continues to fall inward, heating up as it does so, eventually forming a warm core called a protostar. At this stage, the protostar is not yet hot enough for nuclear fusion (the process that powers stars) to occur.</p>



<h3 class="wp-block-heading">Accretion disk</h3>



<p>Around the protostar, material from the surrounding cloud continues to fall inward, forming a rotating disk. This material slowly accretes onto the protostar, increasing its mass.</p>



<h3 class="wp-block-heading">Nuclear fusion begins</h3>



<p>Once the core of the protostar reaches a high enough temperature and pressure, hydrogen atoms begin to fuse into helium, releasing energy in the process. This marks the transition from a protostar to a main sequence star, like our sun.</p>



<h3 class="wp-block-heading">Main sequence and beyond</h3>



<p>The star will spend the majority of its life in the main sequence stage, where it balances the gravitational forces trying to collapse it and the outward pressure from nuclear fusion. </p>



<p>Eventually, the star will exhaust its hydrogen fuel. Its subsequent evolution will depend on its initial mass, leading to various end stages such as red giants, supernovae, neutron stars, or black holes.</p>

Young, massive stars in the Triangulum Galaxy

Today's Image of the Day from the European Space Agency...

<p>Today's Image of the Day from NASA Earth Observatory features the Messak Settafet, a rocky plateau located in the central Sahara Desert. It is part of the greater Messak Plateau, which stretches between the Erg Uan Kasa and the Murzuq Sand Sea.&nbsp;</p>



<p>The plateau's surface is characterized by blackened sandstone, sculpted by thousands of years of wind erosion. This dark patina, often referred to as "desert varnish," adds to its distinctive appearance. The region is starkly beautiful but harsh, with extreme temperatures and minimal <a href="https://www.earth.com/news/even-desert-plants-are-not-immune-to-climate-stress/" target="_blank" rel="noreferrer noopener">vegetation</a>.</p>



<h2 class="wp-block-heading" id="h-image-of-the-messak-settafet">Image of the Messak Settafet</h2>



<p>“Towering over the desert in southwestern Libya, the Messak Settafet plateau resembles the wall of a giant fortress, with its dark, erosion-resistant sandstone separating the Ubari Sand Sea to the north and the Marzūq Sand Sea to the south,” noted NASA.</p>



<p>“The large outcrop of Cretaceous rock features a sharp escarpment on its north side. The cliff, some 300 meters (1,000 feet) high in places, is lined with a thin dark shadow.”&nbsp;</p>



<p>“Dark debris from rockfalls is visible to the north. Note that an optical illusion called relief inversion can make high-elevation areas appear low and vice versa when shadows appear on the northern side of a feature.”</p>



<p>Archaeological significance of the plateau&nbsp;</p>



<p>Messak Settafet is often referred to as the "land of stone tools" because it is one of the world's largest sites for prehistoric tools.&nbsp;</p>



<p>The area is littered with countless <a href="https://search.app?link=https%3A%2F%2Fwww.earth.com%2Fnews%2Fstone-tool-discovery-challenges-entire-theory-of-human-evolution%2F&amp;utm_campaign=aga&amp;utm_source=agsadl2%2Csh%2Fx%2Fgs%2Fm2%2F4" target="_blank" rel="noreferrer noopener">stone tools</a> and artifacts dating back to various prehistoric periods, including the Acheulean and Neolithic. These tools offer insights into early human technology and adaptation to desert environments.</p>



<p>“Signs of ancient tool making cover much of the plateau’s surface,” said <a href="https://www.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>. “According to one archaeological survey, people discarded so many stone tools and rock fragments on the plateau over hundreds of thousands of years that roughly 75 artifacts per square meter now carpet the surface.” </p>



<p>“That makes this one of the earliest known examples of hominins modifying an entire landscape, according to the University of Cambridge archaeologists who conducted the survey.”</p>



<p>“Other signs of ancient activity include the bright spots that dot the image. These areas were likely quarrying pits where people dug up rocks and crafted them into tools, the archaeologists reported.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-rock-art-on-the-plateau-nbsp">Rock art on the plateau&nbsp;</h2>



<p>The plateau is home to numerous petroglyphs and <a href="https://www.earth.com/news/negev-petroglyphs-ancient-art-rock-carvings-face-erosion-fungi-lichens/" target="_blank" rel="noreferrer noopener">carvings</a>. These engravings depict animals, humans, and symbolic designs, providing valuable clues about the lives, beliefs, and environments of the region's ancient inhabitants. </p>



<p>“For instance, Wadi Mathendous, a prehistoric archaeological site located in the southern part of the plateau, contains engravings of rhinoceroses, crocodiles, hippopotamuses, fighting cats, giraffes, long-horned buffaloes, and elephants. The art is thought to be about 8,000 years old,” said NASA.</p>



<p>Some of the animals depicted, such as giraffes and elephants, indicate that the Sahara was once a <a href="https://search.app?link=https%3A%2F%2Fwww.earth.com%2Fnews%2Fa-lush-green-sahara-desert-helped-early-humans-migrate-out-of-africa%2F&amp;utm_campaign=aga&amp;utm_source=agsadl2%2Csh%2Fx%2Fgs%2Fm2%2F4" target="_blank" rel="noreferrer noopener">much wetter</a> and more hospitable environment.</p>



<p>Cultural significance of the Messak Settafet</p>



<p>Messak Settafet forms part of the Rock-Art Sites of Tadrart Acacus, a UNESCO World Heritage Site since 1985. This designation highlights the area's importance for understanding early human culture and environmental changes in the Sahara.</p>



<p>The plateau has been a critical area for studying the migration and adaptation of early humans. Its archaeological richness offers a glimpse into how humans thrived in this region during periods when the climate was wetter.</p>



<p>“Although the plateau now receives less than 0.4 inches of rain annually, clues in the landscape make clear it was once much wetter,” noted NASA.</p>



<p>“Deeply incised dried stream valleys, or wadis, crisscross the plateau, indicating significant past water flow. The small, bright features scattered across the plateau are sand and silt deposits left where water once pooled.”</p>



<p>The Messak Settafet, like many remote <a href="https://www.earth.com/news/sahara-desert-dust-storms-carry-harmful-bacteria-and-fungi-around-the-globe/" target="_blank" rel="noreferrer noopener">desert</a> regions, faces challenges such as erosion, vandalism of ancient rock art, and the potential impacts of development. Efforts to preserve its archaeological treasures are vital for protecting its cultural and scientific significance.</p>

Grand Bahama: A blend of beauty and resilience 

<p>Today's <strong>Image of the Day</strong> from NASA Earth Observatory features an astronaut view of the Aladaghlar Mountains in northwestern Iran.</p>



<p>These <a href="https://www.earth.com/news/how-and-why-do-mountains-form-new-theories-for-an-age-old-mystery/" target="_blank" rel="noreferrer noopener">mountains</a> are known for their strikingly colorful landscapes, which make them stand out among other mountain ranges.</p>



<h2 class="wp-block-heading" id="h-landscape-of-the-aladaghlar-mountains">Landscape of the Aladaghlar Mountains</h2>



<p>"Ridges cast shadows in the valleys and other low elevation areas, creating a three-dimensional appearance. Human alterations to the landscape are most evident in riverbeds, where the even topography is easier to build on and navigate," said <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.</p>



<p>"Natural processes over millions of years have folded rock layers of various compositions and colors into the curved patterns seen here. These folds are produced by tectonic forces operating along the convergent plate boundary of the Arabia and Eurasia plates." </p>



<h2 class="wp-block-heading" id="h-the-rainbow-mountains">The Rainbow Mountains</h2>



<p>One of the most remarkable features of the Aladaghlar Mountains is the vivid coloration of their slopes. </p>



<p>The name "Aladaghlar" translates to "colorful mountains," which is a testament to their unique appearance.&nbsp;They are also known as the Rainbow Mountains.</p>



<h2 class="wp-block-heading" id="h-wildlife-of-the-aladaghlar-mountains">Wildlife of the Aladaghlar Mountains </h2>



<p>The Aladaghlar Mountains are part of a larger <a href="https://www.earth.com/news/mountain-ecosystems-are-in-urgent-need-of-protection/" target="_blank" rel="noreferrer noopener">ecosystem</a> that includes forests, meadows, and rivers, contributing to a rich biodiversity. </p>



<p>The region supports a variety of wildlife, including several species that are unique to the area. The diverse wildlife add to the natural beauty and ecological importance of these <a href="https://www.earth.com/news/how-and-why-do-mountains-form-new-theories-for-an-age-old-mystery/" target="_blank" rel="noreferrer noopener">mountains</a>.</p>



<p>Among the larger mammals, the mountains host species such as brown bears, Persian leopards, and wild goats. The Aladaghlar Mountains also support smaller mammals, including foxes, hares, and various rodent species.&nbsp;</p>



<p><a href="https://www.earth.com/news/how-mountains-influence-bird-evolution/" target="_blank" rel="noreferrer noopener">Birdlife</a> is abundant, including eagles, falcons, and a variety of songbirds. Reptiles like lizards and snakes are commonly found in the more humid areas, as well as amphibians.&nbsp;</p>



<h2 class="wp-block-heading" id="h-cultural-significance-of-the-region">Cultural significance of the region</h2>



<p>In addition to their natural appeal, the Aladaghlar Mountains hold cultural significance. The region has a rich history, with evidence of ancient civilizations and historical sites. </p>



<p>Local communities have their unique cultures and traditions, which have been influenced by the natural environment of the mountains.</p>



<h2 class="wp-block-heading" id="h-geology-of-the-aladaghlar-mountains-nbsp">Geology of the Aladaghlar Mountains&nbsp;</h2>



<p>The geological history of these <a href="https://www.earth.com/news/mountains-both-carbon-sinks-and-carbon-sources/" target="_blank" rel="noreferrer noopener">mountains</a> is a fascinating tale of millions of years of natural processes.</p>



<p>The Aladaghlar Mountains are primarily composed of sedimentary rocks that have accumulated over millions of years. These sediments include sandstones, siltstones, shales, and conglomerates.</p>



<h3 class="wp-block-heading" id="h-mineral-deposition-nbsp">Mineral deposition&nbsp;</h3>



<p>The varying colors of the Aladaghlar Mountains are largely due to the presence of different minerals in the sedimentary layers. For example, red and orange hues are typically due to iron oxides, while greens can result from copper compounds.</p>



<p>These minerals were deposited in the sedimentary rocks through processes such as chemical precipitation, biological activity, and the weathering of parent rocks.</p>



<h3 class="wp-block-heading" id="h-tectonic-activity">Tectonic activity</h3>



<p>The region has experienced significant tectonic activity due to its location near the convergent boundary between the Arabian and Eurasian plates. This tectonic activity has caused the uplift and folding of the sedimentary layers, creating the mountain range.</p>



<p>The compression and folding associated with tectonic movements have also contributed to the exposure of the colorful strata that were originally deposited horizontally.</p>



<h3 class="wp-block-heading" id="h-erosion-and-weathering">Erosion and weathering</h3>



<p>Over time, erosion and weathering processes have played a crucial role in shaping the Aladaghlar Mountains. </p>



<p>Wind, water, and temperature variations have eroded the softer rock layers more quickly than the harder ones, creating the distinctive ridges and valleys seen today.</p>



<p>These erosive processes have also helped to expose the underlying layers, revealing the vibrant colors and intricate patterns that attract tourists and geologists alike.</p>



<h2 class="wp-block-heading">Tales and legends</h2>



<p>One of the most famous tales associated with the Aladaghlar Mountains is that of a hidden treasure buried deep within the mountains by an ancient Persian king.&nbsp;</p>



<p>According to legend, the treasure is guarded by mystical creatures and can only be found by someone pure of heart and brave enough to face the challenges of the mountain.</p>



<h3 class="wp-block-heading">The shepherd and the fairy</h3>



<p>Another local legend tells the story of a young shepherd who fell in love with a fairy he encountered in the Aladaghlar Mountains. The fairy granted the shepherd three wishes, but warned him that the wishes would come with consequences.&nbsp;</p>



<p>Despite the warning, the shepherd made his wishes, which ultimately led to his downfall, serving as a cautionary tale about the dangers of greed.</p>



<h3 class="wp-block-heading">The healing springs</h3>



<p>The Aladaghlar Mountains are also said to be home to a spring with magical healing properties. According to folklore, those who bathe in the spring or drink its water are cured of all ailments.&nbsp;</p>



<p>However, the location of the spring is a closely guarded secret, known only to a few wise elders in the nearby villages.</p>



<h3 class="wp-block-heading">The spirit of the mountain&nbsp;</h3>



<p>Some locals believe that the Aladaghlar Mountains are inhabited by a protective spirit, who watches over the land and its people.&nbsp;</p>



<p>This spirit is said to bring good fortune to those who respect the mountain and its natural beauty, but misfortune to those who exploit or harm it.</p>

The Aladaghlar Mountains of northwestern Iran

<p>Today's <strong>Image of the Day</strong> from NASA Earth Observatory features the Corbassière glacier, a high-altitude glacier in Switzerland. The glacier originates on the northern slope of the Grand Combin, which is one of the highest peaks in the Pennine Alps.</p>



<p>Collectively, the <a href="https://www.earth.com/news/alpine-glaciers-will-lose-half-of-their-volume-by-2050/" target="_blank" rel="noreferrer noopener">alpine glaciers</a> of Switzerland have lost more than half of their volume since the 1930s.</p>



<h2 class="wp-block-heading" id="h-natural-archives-of-past-climate">Natural archives of past climate </h2>



<p>"Glaciers are natural archives of past climate. In their frozen layers lies evidence of Earth’s changing temperature and atmospheric composition. But as the climate warms, some of the longest records of our changing planet are melting away," said <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA</a>.</p>



<p>"In just over two decades, Corbassière has shrunk in area and surface mass. The glacier was darker in 2023 due to lack of snow, and the glacier’s tongue had retreated."</p>



<h2 class="wp-block-heading" id="h-ice-cores-from-the-corbassiere-glacier">Ice cores from the Corbassière glacier</h2>



<p>To reconstruct past concentrations of atmospheric <a href="https://www.earth.com/news/how-do-aerosols-impact-the-climate/" target="_blank" rel="noreferrer noopener">aerosols</a>, a team of scientists analyzed ice cores that were collected from the Corbassière glacier in 2018 and 2020.&nbsp;</p>



<p>Aerosols are tiny airborne particles that are deposited in the ice. "Such information from glaciers around the world can provide clues about past environmental conditions thousands of years ago," noted NASA.</p>



<p>"Ice cores contain ammonium, nitrate, and sulfate ions - signatures of aerosols lacing the snow that’s deposited on glaciers year after year. Ion concentrations are lower in winter than in summer because less polluted air can rise from the valley when the air is cold."</p>



<p>When the researchers analyzed the ice core from 2018, they found seasonal fluctuations in the amount of ion deposits - which is what they expected to find.&nbsp;</p>



<p>"But when we went to core the glacier in 2020, we noticed melting on the surface right away,” said Margit Schwikowski, an environmental chemist at <a href="https://www.psi.ch/en" target="_blank" rel="noreferrer noopener">Paul Scherrer Institute</a> in Switzerland.&nbsp;</p>



<h2 class="wp-block-heading" id="h-rapid-surface-melting-on-corbassiere-glacier">Rapid surface melting on Corbassière glacier</h2>



<p>The experts determined that melting on the glacier's surface likely penetrated the glacier layers below and carried away the aerosol ions. </p>



<p>"This melting rendered the core unusable in the team’s research, and other attempts to core the glacier had the same result. The valuable information stored in the ice was destroyed," explained NASA.</p>



<p>Schwikowski has joined a team of other experts in an effort to preserve cores from the last remaining glaciers. Led by the <a href="https://www.ice-memory.org/" target="_blank" rel="noreferrer noopener">Ice Memory Foundation</a>, the goal of the project is to obtain ice cores from 20 endangered glaciers around the world in 20 years and collect them in a global <a href="https://www.earth.com/news/antarcticas-ice-has-a-history-of-rapid-and-unexpected-changes/" target="_blank" rel="noreferrer noopener">climate archive</a>.</p>



<p>“Glaciers are retreating worldwide, and we may find similar issues at other sites,” said Schwikowski. She added that even at the highest altitudes in the Alps, "glaciers are on the verge of becoming unsuitable as natural paleo-archives."</p>



<h2 class="wp-block-heading" id="h-features-of-the-corbassiere-glacier">Features of the Corbassière Glacier</h2>



<p>The Corbassière Glacier is a captivating natural feature located in the Swiss Alps, part of the canton of Valais. </p>



<p>The glacier stretches over approximately 9 kilometers, making it one of the significant glaciers in the region. It originates from the Grand Combin, an imposing mountain massif that reaches heights of over 4,300 meters, contributing greatly to the glacier's nourishment through snow and ice accumulation.</p>



<p>A distinct feature of the Corbassière Glacier is its accessibility and the dramatic scenery it offers, which attracts many hikers and nature enthusiasts. </p>



<p>One of the most notable attractions near the <a href="https://www.earth.com/news/doomsday-glacier-seems-to-have-lost-its-ability-to-recover/" target="_blank" rel="noreferrer noopener">glacier</a> is the Corbassière footbridge, a 210-meter long suspension bridge that provides stunning views of the glacier and the surrounding peaks. </p>



<p>This bridge not only enhances the experience for visitors but also serves as a crucial observation point for scientists studying glacier dynamics and the effects of climate change.</p>



<h2 class="wp-block-heading">The Swiss Alps&nbsp;</h2>



<p>The Swiss <a href="https://www.earth.com/news/snow-cover-in-the-alps-could-soon-be-cut-in-half/" target="_blank" rel="noreferrer noopener">Alps</a> are a majestic and expansive mountain range that stretches across the southern part of Switzerland, forming a part of the greater Alpine region that spreads across several countries in Europe.&nbsp;</p>



<p>Renowned for their stunning beauty and formidable peaks, the Swiss Alps are not just a geographical landmark but also a cultural symbol of Switzerland, epitomizing its identity as a nation of scenic landscapes and outdoor adventure.</p>



<p>The region is famous for its dramatic scenery, including towering mountains, pristine lakes, and picturesque valleys. Among these peaks are some of the highest in Europe, such as the Dufourspitze, part of the Monte Rosa massif, which is the highest point in Switzerland. </p>



<p>The Matterhorn, perhaps the most iconic of all Swiss mountains, is celebrated for its unique, pyramid-like shape and is a magnet for climbers and tourists alike.</p>

The Corbassière glacier in the Swiss Alps

<p>Have you ever wondered if crabs and lobsters felt pain or fear as they were being boiled alive before making it onto your dinner plate? </p>



<p>Recent studies suggest that these creatures experience discomfort in ways we hadn't fully understood before.</p>



<p>Dr. Lynne Sneddon, a zoophysiologist at the <a href="https://www.gu.se/en" target="_blank" rel="noreferrer noopener">University of Gothenburg</a>, believes it's time we reconsider how we treat these animals. </p>



<p>"We need to find less painful ways to kill shellfish if we are to continue eating them. Because now we have scientific evidence that they both experience and react to pain," she says.</p>



<h2 class="wp-block-heading" id="h-understanding-crustaceans-the-basics">Understanding crustaceans -- the basics</h2>



<p>Crustaceans have been <a href="https://www.earth.com/news/bright-coloration-in-crayfish-does-not-serve-an-evolutionary-purpose/" target="_blank" rel="noreferrer noopener">roaming the Earth</a> for an impressive span of over 500 million years. </p>



<p>They first appeared during the Cambrian period, a time known for the "<a href="https://www.earth.com/news/grand-canyon-fossils-reveal-secrets-of-the-cambrian-explosion/" target="_blank" rel="noreferrer noopener">Cambrian Explosion</a>" when many major animal groups emerged. </p>



<p>Early crustaceans already showcased the key features we recognize today, such as their hard <a href="https://www.earth.com/news/shellfish-consumed-by-humans-are-ironically-more-resistant-to-extinction/" target="_blank" rel="noreferrer noopener">exoskeletons</a>, segmented bodies, and jointed limbs. </p>



<p>This long evolutionary history has allowed them to diversify into <a href="https://www.earth.com/news/meet-melita-panda-the-black-and-white-crustacean-shrimp/" target="_blank" rel="noreferrer noopener">thousands of species</a>, adapting to a wide range of environments from the deepest parts of the oceans to freshwater rivers and even some terrestrial areas.</p>



<p>Crustaceans, such as crabs and lobsters, are more than just seafood delicacies. <a href="https://www.earth.com/news/do-crabs-and-lobsters-have-emotions-and-feelings/" target="_blank" rel="noreferrer noopener">These fascinating creatures</a> boast a hard exoskeleton made of chitin, providing them with protection and support. </p>



<p>With ten legs -- often featuring claws or pincers -- they navigate their environments with ease. </p>



<p>Their bodies are segmented into the head, thorax, and abdomen, and they have specialized appendages for swimming, walking, or digging.</p>



<p>These <a href="https://www.earth.com/news/new-deep-sea-crustacean-species-discovered-in-the-bahamas/" target="_blank" rel="noreferrer noopener">adaptable animals</a> can be found almost everywhere: from the deepest ocean trenches to freshwater rivers and even damp terrestrial spots. </p>



<h2 class="wp-block-heading" id="h-crabs-pain-and-perception">Crabs, pain, and perception</h2>



<p>Until now, the idea that crustaceans feel pain was mostly based on observational studies. </p>



<p>Researchers noticed that when crabs and lobsters were exposed to potentially harmful stimuli -- like electric shocks or acids -- they would touch the affected area or try to avoid the danger in subsequent encounters. </p>



<p>This behavior led many to believe they might be experiencing pain.</p>



<p>But the team at the University of Gothenburg took it a step further. PhD student Eleftherios Kasiouras led a study where they measured the activity in a shore crab's brain using EEG-style recordings. </p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/11/crabs_feel-pain_electrodes_shore-crab_Eleftherios-Kasiouras_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/11/crabs_feel-pain_electrodes_shore-crab_Eleftherios-Kasiouras_1s.webp" alt="Electrodes measuring brain activity were attached to a shore crab, which was then subjected to mechanical and chemical stimuli. Credit: Eleftherios Kasiouras" class="wp-image-1951623"/></a><figcaption class="wp-element-caption"><em>Electrodes measuring brain activity were attached to a shore crab, which was then subjected to mechanical and chemical stimuli. Credit: Eleftherios Kasiouras</em></figcaption></figure>



<p>"We could see that the crab has some kind of pain receptors in its soft tissues, because we recorded an increase in brain activity when we applied a potentially painful chemical, a form of vinegar, to the crab's soft tissues. The same happened when we applied external pressure to several of the crab's body parts," he explains.</p>



<p>These findings suggest that shore crabs have a pain signaling system that sends messages to their brains when they experience harmful stimuli. </p>



<p>Interestingly, the pain response was shorter and more intense with physical stress, while chemical stress produced a longer-lasting effect.</p>



<h2 class="wp-block-heading" id="h-if-crabs-feel-pain-what-about-lobsters">If crabs feel pain, what about lobsters?</h2>



<p>Given that many crustaceans share similar structures and nervous systems, these results could extend beyond shore crabs. </p>



<p>"It is a given that all animals need some kind of pain system to cope by avoiding danger. I don't think we need to test all species of crustaceans, as they have a similar structure and therefore similar nervous systems," Kasiouras explains.</p>



<p>"We can assume that shrimps, crayfish, and lobsters can also send external signals about painful stimuli to their brain which will process this information."</p>



<h2 class="wp-block-heading" id="h-importance-of-crustaceans">Importance of crustaceans</h2>



<p>Crustaceans play <a href="https://www.earth.com/news/why-did-billions-of-crabs-vanish-from-the-bering-sea/" target="_blank" rel="noreferrer noopener">vital roles in their ecosystems</a>. Acting as both predators and prey, they help maintain the balance of marine and freshwater food webs.</p>



<p>For humans, they are a significant food source, contributing to economies worldwide. They're also valuable in scientific research, aiding studies on regeneration, development, and environmental health.</p>



<p>However, challenges like overfishing and habitat destruction <a href="https://www.earth.com/news/crabs-are-losing-their-sense-of-smell-and-vanishing-due-to-ocean-acidification/" target="_blank" rel="noreferrer noopener">threaten their populations</a>. This raises concerns about sustainability and the need for better practices to ensure these creatures thrive for future generations.</p>



<h2 class="wp-block-heading" id="h-reconsidering-how-we-handle-seafood">Reconsidering how we handle seafood</h2>



<p>Currently, shellfish like prawns, lobsters, crabs, and <a href="https://www.earth.com/news/global-crayfish-atlas-offers-new-tools-for-conservation/" target="_blank" rel="noreferrer noopener">crayfish aren't covered</a> by animal welfare legislation in the European Union. </p>



<p>This means practices that might cause them pain are still legally acceptable. But with new evidence pointing to their ability to feel pain, there's a growing call to change how we treat these animals.</p>



<p>Dr. Sneddon emphasizes the need for change: "We need more research to find less painful ways to kill shellfish." </p>



<p>If we continue to consume these creatures, it's crucial to ensure we're not causing unnecessary suffering.</p>



<h2 class="wp-block-heading" id="h-this-is-awful-but-what-can-we-do">This is awful, but what can we do?</h2>



<p>The first step is acknowledging that these animals might experience pain similarly to how we do. </p>



<p>With that understanding, industries and regulators can work towards implementing more humane methods of handling and killing <a href="https://www.earth.com/news/strawberry-claws-the-hermit-crab-that-sings-underwater/" target="_blank" rel="noreferrer noopener">crustaceans</a>. </p>



<p>This could involve developing new technologies or techniques that minimize pain or distress.</p>



<p>Consumers also play a role. By supporting businesses that prioritize humane practices and advocating for better regulations, we can encourage a shift towards more ethical treatment of these animals.</p>



<h2 class="wp-block-heading" id="h-crabs-pain-and-human-compassion">Crabs, pain, and human compassion</h2>



<p>As we learn more about the creatures we share our planet with, it's essential to adapt our behaviors accordingly. </p>



<p>Knowing that crabs, lobsters, and other crustaceans can feel pain changes the game on how we should treat them, especially when it comes to cooking and handling. </p>



<p>It's not just about following laws or guidelines -- it's about being mindful and compassionate in our everyday choices, treating sentient creatures with respect. </p>



<p>By supporting humane practices and staying informed, we can help ensure that all crustaceans are treated with the respect they've earned by inhabiting our planet for over 500 million years.</p>



<p>As we move forward, both industries and individuals have a part to play. After all, how we treat the smallest of creatures often reflects our values as a society.</p>

Immediate ban on boiling crabs and lobsters called for after disturbing study

Have you ever wondered if crabs and lobsters felt pain...

<p>About 6 million years ago, an extraordinary event occurred that restructured the Mediterranean and its water. This phenomenon, known as the Messinian Salinity Crisis, transformed the sea into a massive salt basin.</p>



<p>But how did a million cubic kilometers of salt come to rest in such a short time on the Mediterranean seabed? Until now, that remained a mystery.</p>



<p>Now, scientists have made a significant breakthrough. By analyzing chlorine isotopes found in the salt on the Mediterranean seabed, they've unveiled the two distinct phases of this intense evaporation event.</p>



<h2 class="wp-block-heading" id="h-phases-of-desiccation-and-salt-accumulation">Phases of desiccation and salt accumulation</h2>



<p>The first desiccation phase lasted approximately 35,000 years. During this time, salt deposition occurred exclusively in the eastern <a href="https://www.earth.com/image/corsica-sardinia-mediterranean-sea/" target="_blank" rel="noreferrer noopener">Mediterranean</a>. This was due to a restriction of the Mediterranean outflow into the Atlantic, resulting in a brine-filled basin in the east.</p>



<p>The second phase, however, was a different story altogether. Over less than 10,000 years, salt accumulation took place throughout the entire Mediterranean.</p>



<p>An expeditious evaporative event caused such a sharp decline in sea-level - 1.7-2.1 kilometers in the east, and approximately 0.85 kilometers in the west - that the Mediterranean basin lost up to 70% of its total water volume.</p>



<p>Moreover, change on such a monumental scale didn't occur without <a href="https://www.earth.com/news/distress-signals-earths-water-cycle-is-becoming-more-erratic/" target="_blank" rel="noreferrer noopener">repercussions</a>. The effects of the spectacular fall in sea level were far-reaching and not just limited to the marine environment itself.</p>



<h2 class="wp-block-heading" id="h-factors-linked-to-mediterranean-water-loss">Factors linked to Mediterranean water loss</h2>



<p>Local volcanic eruptions may have been triggered due to the release of pressure on Earth's crust. These eruptions could be thought of as Earth's reactions to the rapid loss of such a substantial amount of water weight.</p>



<p>Moreover, this large scale evaporative event also might have influenced global climate patterns. The drastic depression caused by the sea-level drawdown rippled outwards, affecting weather systems far and wide.</p>



<p>These results point towards a better understanding of not just the Messinian Salinity Crisis, but also of the ways extreme desiccation events can drastically alter ecosystems and climates on a global scale.</p>



<p>In the last moments of this salinity crisis, the sea-level of the Mediterranean was almost a kilometer below that of the Atlantic Ocean. This extreme difference lead to the eventual collapse of the Strait of Gibraltar.</p>



<h2 class="wp-block-heading" id="h-mediterranean-water-loss-and-marine-life">Mediterranean water loss and marine life</h2>



<p>The Messinian Salinity Crisis also posed significant challenges for marine life in the Mediterranean basin. </p>



<p>The extreme hypersaline conditions would have been inhospitable for most marine organisms, leading to mass extinctions of species that could not adapt. </p>



<p>However, evidence suggests that some extremophilic organisms (organisms capable of surviving in highly saline environments) managed to persist during this period. </p>



<p>Fossil records indicate that isolated pockets of less saline water, or refugia, may have existed, providing temporary habitats for certain species. These pockets paint a picture of resilience amidst an environment of extreme ecological stress.</p>



<h2 class="wp-block-heading" id="h-restoration-of-the-mediterranean-water">Restoration of the Mediterranean water</h2>



<p>The collapse of the Strait of Gibraltar acted as a gateway for the Atlantic Ocean to flow back into the Mediterranean. This sudden influx of water ended the prolonged desiccation, refilling the Mediterranean basin and restoring its water levels. </p>



<p>As a result, the Mediterranean transitioned from a nearly dry, hypersaline basin dominated by thick salt deposits into a thriving open sea once again, with normal marine conditions and ecosystems returning over time. </p>



<p>This event marked the resolution of the Messinian Salinity Crisis, reshaping the region's geography and ecological dynamics permanently.</p>



<h2 class="wp-block-heading" id="h-modern-climate-challenges">Modern climate challenges</h2>



<p>The insights gained from studying the Messinian Salinity Crisis carry valuable lessons for our understanding of current and future <a href="https://www.earth.com/news/global-drought-has-caused-crisis-levels-of-food-and-water-scarcity/" target="_blank" rel="noreferrer noopener">environmental changes</a>. </p>



<p>This event showcases how rapid geological and hydrological transformations can trigger cascading effects on the climate, ecosystems, and even tectonic activity. </p>



<p>Contemporary concerns about rising temperatures, altering precipitation patterns, and water scarcity echo some of the climate disruptions that may have been felt during the crisis. </p>



<p>By learning from this historic event, scientists emphasize the importance of global collaboration and sustainable resource management to mitigate the impacts of looming environmental challenges on both natural systems and human societies.</p>



<h2 class="wp-block-heading" id="h-significance-of-the-study">Significance of the study</h2>



<p>This research on the history of Mediterranean water has provided fresh insights into historical geological events, enhancing our comprehension of these past occurrences.</p>



<p>By examining these findings, scientists and researchers have the opportunity to improve their predictions about future geological phenomena. </p>



<p>Understanding the patterns and causes of past events allows for better preparation and response strategies, potentially reducing the adverse impacts of similar events that may occur in the future. </p>



<h2 class="wp-block-heading" id="h-learning-from-geological-history">Learning from geological history</h2>



<p>The study emphasizes the importance of learning from past geological activities to make informed decisions that safeguard communities and environments against natural disasters. It raises a critical question: will we apply the lessons learned to protect our future? </p>



<p>The findings from the study serve as a call to action, urging society to integrate historical lessons into future planning and preparedness efforts.</p>



<p>The study was led by G. Aloisi, a scientist at the French National Centre for Scientific Research (<a href="https://www.cnrs.fr/en" target="_blank" rel="noreferrer noopener">CNRS</a>), which is one of the largest governmental research organizations in France.</p>

The Mediterranean Sea lost almost all of its water, triggering a global crisis

About 6 million years ago, an extraordinary event occurred that...

<p>As the global community continues its fight against emerging strains of the coronavirus, long-COVID emerges as another significant battle. Its persistent, debilitating symptoms hinder the daily lives of millions of people worldwide.</p>



<p>In the United States, one in thirteen adults have experienced long COVID challenges such as widespread pain, fatigue, and reduced mobility - prompting scientists to seek innovative solutions to ease the struggle.</p>



<h2 class="wp-block-heading" id="h-relief-for-long-covid-patients">Relief for long-COVID patients</h2>



<p>To tackle this new health challenge, researchers at <a href="https://www.uclahealth.org/" target="_blank" rel="noreferrer noopener">UCLA Health</a> and <a href="https://www.bcm.edu/" target="_blank" rel="noreferrer noopener">Baylor College of Medicine</a> have explored the use of a wearable device that could offer much-needed relief.</p>



<p>The device utilizes Transcutaneous Electrical Nerve Stimulation (TENS) technology, employing low-voltage electric currents to alleviate pain, <a href="https://www.earth.com/news/cause-of-fatigue-in-long-covid-patients-has-finally-been-revealed/" target="_blank" rel="noreferrer noopener">fatigue</a>, and mobility problems that are tied to long-COVID.</p>



<p>The findings were recently shared in the peer-reviewed academic journal <em>Nature Scientific Reports</em>.</p>



<h2 class="wp-block-heading" id="h-conditions-involving-chronic-fatigue-and-pain">Conditions involving chronic fatigue and pain</h2>



<p>The potential of the TENS device extends beyond the realm of long-COVID.</p>



<p>Dr. Bijan Najafi, the research director at UCLA Health's Center for Advanced Surgical &amp; Interventional Technology, also foresees its broader applications in other fields of healthcare.</p>



<p>“While this study focused on managing pain and fatigue caused by long-COVID, it may also have potential applications for addressing similar symptoms in individuals with other <a href="https://www.earth.com/news/many-americans-underestimate-the-threat-of-respiratory-virus-season/" target="_blank" rel="noreferrer noopener">respiratory</a> diseases, those who have experienced extended ICU stays and developed post-hospitalization weaknesses, and conditions involving chronic fatigue and pain, such as fibromyalgia or chemotherapy-related side effects,” he explained.</p>



<p>However, Dr. Najafi emphasized the need for further studies to confirm these potential uses.</p>



<h2 class="wp-block-heading" id="h-mitigating-the-impacts-of-long-covid">Mitigating the impacts of long-COVID</h2>



<p>For the investigation, 25 participants suffering from chronic musculoskeletal pain, fatigue, and gait issues were divided into two groups.</p>



<p>One group was provided with a high-dose (active) TENS device, and the other group was given a low-dose (placebo) device. </p>



<p>The devices were used by the participants for three to five hours daily for a span of four weeks. The study focused on before-and-after comparisons of pain level, fatigue, and walking performance in the participants.</p>



<p>The high-dose TENS group showed considerable progress, with 26.1% more pain relief and an 8% improvement in fast walking, when compared to the placebo group.</p>



<p>This implies that wearable TENS therapy could be a useful tool in mitigating long-COVID's impacts on daily life.</p>



<h2 class="wp-block-heading" id="h-on-demand-relief-for-long-covid-patients">On-demand relief for long-COVID patients </h2>



<p>The success of the TENS device can be attributed to its convenient, wearable design.</p>



<p>As observed by Dr. Najafi, the daily usage rates were high because users could effortlessly integrate the device into their regular routines.</p>



<p>“This wearable TENS system offered immediate, on-demand relief from pain and fatigue, making it easy to integrate into daily activities,” noted Dr. Najafi.</p>



<h2 class="wp-block-heading" id="h-further-research-is-needed">Further research is needed</h2>



<p>While the results are promising, Dr. Najafi also highlighted the need for further research to comprehensively investigate the effectiveness of this device.</p>



<p>“This study provides some hope for finding an effective, non-invasive solution for managing lingering <a href="https://www.earth.com/news/paxlovid-helps-fight-covid-but-it-does-not-prevent-long-covid-symptoms/" target="_blank" rel="noreferrer noopener">COVID-19 symptoms</a> that continue to affect millions. But our sample size was limited, so further research is needed to confirm these findings,” he cautioned.</p>



<p>By coupling the power of technology with medical science, we are now one step closer to finding relief for those afflicted by long-COVID.</p>



<p>It’s a reflection of the human spirit's resilience and our relentless pursuit of wellness in the face of adversity.</p>



<h2 class="wp-block-heading" id="h-tackling-long-covid-with-holistic-approaches">Tackling long-COVID with holistic approaches</h2>



<p>While wearable TENS technology appears promising, there&nbsp;is&nbsp;still&nbsp;a&nbsp;need to adopt&nbsp;a holistic approach towards managing long-COVID.</p>



<p>Integrating TENS therapy with other <a href="https://www.earth.com/news/long-covid-leaves-blood-markers-that-can-be-targeted-for-treatment/" target="_blank" rel="noreferrer noopener">rehabilitation</a> techniques - like physical therapy, nutritional support, and mental health interventions - could offer a more complete approach towards recovery.</p>



<p>Long-COVID is a complex condition, and its impact varies greatly among individuals. It&nbsp;requires an interprofessional approach, where customized&nbsp;care plans are&nbsp;devised, taking into account the patient's unique needs.</p>



<p>Incorporation&nbsp;of&nbsp;<a href="https://www.earth.com/news/wearable-imaging-device-reveals-infant-brain-activity/" target="_blank" rel="noreferrer noopener">wearable technologies</a> into these broad&nbsp;treatment protocols&nbsp;may&nbsp;improve treatment effectiveness and&nbsp;the quality of life&nbsp;of&nbsp;those affected.</p>



<p>As research continues, the hope is to build a toolkit of solutions that not only targets the physical challenges of long-COVID but also supports emotional resilience and overall well-being.</p>



<p>The full study was published in the journal <em><a href="https://www.nature.com/articles/s41598-024-78651-5" target="_blank" rel="noreferrer noopener">Scientific Reports</a></em>.</p>

<p><span style="font-weight: 400;">Today’s </span><b>Video of the Day</b><span style="font-weight: 400;"> comes from Hawaii where a boat of tourists witnessed molten lava shooting out of a collapsed volcano and into the ocean. </span></p>
<p><span style="font-weight: 400;">The scene occurred at Hawaii Volcanoes National Park at the site of the Kamokuna lava delta. The delta, a 26-acre volcanic rock formation, had collapsed 10 days prior. Just last week, we featured photos of that collapse on <a href="https://www.earth.com/image/lava-delta-collapses-ocean/">Image of the Day</a>.</span></p>
<p><span style="font-weight: 400;">According to a spokesman for </span><a href="https://www.nps.gov/havo/"><span style="font-weight: 400;">Hawaii Volcanoes National Parks Service</span></a><span style="font-weight: 400;">, the delta is considered “extremely dangerous.” </span></p>
<p><span style="font-weight: 400;">“Lava deltas are extremely hazardous volcanic features and are formed when lava enters the ocean and builds new land on loose and unstable substrate,” the spokesman explained. “In addition to the threat of collapse, lava entering the ocean produces a highly corrosive plume of hydrochloric acid and volcanic particles that irritate the lungs, skin and eyes. Visitors are strongly urged to stay out of closed areas and heed all posted warning signs.”</span></p>
<p><span style="font-weight: 400;">The footage was shot by Captain Shane Turpin of Lava Ocean Tours.</span></p>
<p><span style="font-weight: 400;">“This was a real rare sight as the guests watched in awe,” said Turpin. “First the boat went silent to the point </span><span style="font-weight: 400;">one could hear the sloshing sizzling molten lava hose as it rushed from the earth into the sea. But this was then followed by cheering and gasps at the once-in-a-lifetime experience we all just witnessed.” </span></p>
<p>&#8216;The heat is real however not to a point that it was uncomfortable and actually it felt quite nice,” he added.</p>
<p>When lava is released from the ground, it can range in temperature from 700 to 1,200 degrees Celsius (1,292 to 2,192 degrees Fahrenheit).</p>
