Melting Antarctic Ice Could Awaken 100 Hidden Volcanoes
Mount Erebus, Antarctica, is the most southerly active volcano on Earth. Credit: Josh Landis/National Science Foundation, Public Domain When glaciers melt, they expose more than just ancient landscapes. Beneath the West Antarctic Ice Sheet lies a fiery secret—active volcanoes that may become more restless as the ice retreats. In a new study, researchers reveal how the……

Scorching climate drove lampreys apart during cretaceous period
A new study finds that one of the hottest periods in Earth’s history may have driven lampreys apart — genetically speaking. The work could have implications for how aquatic species respond to our current changing climate. “Lampreys are simultaneously creepy and special — even though people tend to think of them as just tubes with…

Discovery of ‘Punk’ and ‘Emo’ fossils challenges our understanding of ancient molluscs
Researchers have unearthed two fossils, named Punk and Emo, revealing that ancient molluscs were more complex and adaptable than previously known. Molluscs are one of life’s most diverse animal groups and analysis of the rare 430 million year old fossils is challenging long-held views on their early origins. The fossils dating from the Silurian period…

Dopamine and Serotonin Drive Emotional Word Processing
Summary: Researchers have uncovered how neurotransmitters in the brain respond to the emotional content of language, shedding light on the intersection of emotion, cognition, and communication. Using advanced techniques, the team simultaneously measured dopamine, serotonin, and norepinephrine release in patients during exposure to emotionally charged words. They found distinct patterns of… Continue Reading News Source:…

New Study Shows ‘Anomalous Rocks’ Deep Inside Earth
A new computer model shows blobs of cooler rocks (in blue) in Earth’s mantle where none should be. Sebastian Noe/ETH Zurich A team of geophysicists created a detailed model of Earth’s lower mantle using earthquake waves. This indicates the presence of zones of rocks that are colder, or have a different composition, than our current…

Retrieving the first-ever sample from Mars will be left to Trump’s NASA.
Retrieving the first-ever sample from Mars will be left to Trump’s NASA. “This is going to be a function of the new administration in order to fund this,” NASA Administrator Bill Nelson said during a press conference today, according to Ars Technica. But will Jared Isaacman, Donald Trump’s pick to lead the agency, take up the…

Warming threatens flies more than bees, raising pollination concerns
New research shows flies can tolerate temperatures 2.3°C lower than bees before losing motor function, making them particularly vulnerable to climate change and raising concerns about their crucial role as the world’s second most important pollinators. The study, conducted across three countries, reveals that flies’ sensitivity to heat is especially… Continue Reading News Source:…
