Marine life is thriving on the Antarctic seafloor, even after being trapped under the ice for 50 years
Researchers have discovered that the Antarctic seabed is teeming a rich community of sea creatures. The marine organisms – trapped under the ice for five decades – came to light after an iceberg over two times bigger than New York City broke off of the Brunt Ice Shelf in northern Antarctica last month. The iceberg, called A-74, drifted into the Weddell Sea […]

Ice cores from top-secret Army base reveal Greenland was largely ice-free millions of years ago
A new study published in the journal PNAS suggests that Greenland might have been largely ice-free millions of years ago. Researchers arrived at this conclusion after studying ice core samples that U.S. Army scientists dug from a mile below northwestern Greenland in 1966 as part of a top-secret project codenamed “Iceworm.” The ice core was lost in a freezer for decades before it was […]

It turns out, having a healthy gut can make you “fear less”
A study led by Weill Cornell Medicine in New York City has shown that a healthy gut can make you “fear less” by extinguishing your fear memories. In an article published in the journal Nature, the researchers detailed how they used mice to explore the ability to unlearn fear responses. Exploring the gut’s role in fear response It has become increasingly […]

Analysis of mutated fern spores sheds light on link between mercury and mass extinction
A study published in the journal Science Advances found that increased mercury levels in the environment may have contributed to the mass extinction more than 200 million years ago. An international team of researchers analyzed mutated fern spores from core samples dating to that period and found a strong link between mercury and the mass extinction event. “By looking […]

Accumulation of ammonia from agriculture linked to cloud formations over Asia
European researchers found that cloud formations over Asia are influenced by ammonia from agriculture. In a paper published in the journal Nature Geoscience, the researchers described how ammonia from livestock and fertilizers rises up into the atmosphere to form a seasonal aerosol layer. Aerosol layer largely made up of ammonia-based chemical The Asian tropopause aerosol layer (ATAL) is an accumulation of […]

Personalized nutrition: Researchers identify connection between genetic variation and gut bacteria
Researchers uncovered a previously unknown link between genetic variation and gut bacteria which could help nutritionists personalize their recommendations. In a paper published in the journal Cell Host & Microbe, American and Egyptian researchers reported that having many copies of the gene alpha-amylase 1 (AMY1) is associated with increased populations of gut bacteria that play an important role in […]

Study: Watching virtual reality videos of the North Pole found to reduce chronic pain
Researchers from Imperial College London have found that watching virtual reality (VR) videos of the North Pole helps relieve chronic pain. In a study published in Pain Reports, the researchers reported that VR therapy helps reduce perceived pain levels and pain sensitivity. Virtual reality an effective pain reliever The researchers mimicked the heightened sensitivity of people with chronic pain […]

Green scream: Plants emit “ultrasonic squeals” when stressed by drought or physical damage
Plants let out “ultrasonic squeals” when they are damaged or stressed by drought. Researchers at Tel Aviv University in Israel discovered this after placing microphones near tomato and tobacco plants. Thanks to the microphones, the researchers were able to detect distinct sounds emanating from the plants. The sounds are too high-frequency for humans to hear, but other plants and some animals may be able to perceive […]

Vesuvius eruption wiped out people of Pompeii because it lasted longer than 15 minutes, study finds
A new study suggests that the eruption of Mount Vesuvius two millennia ago may have killed the inhabitants of the ancient city of Pompeii because it lasted longer than 15 minutes. The majority of the victims died of asphyxiation, or suffocation, caused by a giant cloud of ash and toxic gases. In a study published in the […]

Study shows how plants time their flowering in the spring
A new study published in the journal Genes & Development found that a key molecule in flowering plants becomes very active in response to the first frost of autumn. Called “COOLAIR,” the molecule prepares plants for flowering in spring by suppressing a gene called FLOWERING LOCUS C (FLC), which inhibits flowering. Exploring the molecular process behind vernalization Vernalization is the initiation of […]
