The Arctic is not the most welcoming place on Earth. Some Arctic animals like reindeer have some genetic adaptations to help them thrive there, and one of the region’s top predators is no exception. Scientists are teaming up when polar bears (Ursus maritimus) may have evolved some of the genes
Nearly three in four of us will face extreme weather changes within the next two decades, a new study predicts. “At best, we calculate that the rapid changes will affect 1.5 billion people,” says physicist Bjørn Samset of the Center for International Climate Research (CICERO) in Norway. This lower rating
Life and death are traditionally seen as opposites. But the emergence of new multicellular life forms from the cells of a dead organism ushers in a “third state” that extends beyond the traditional boundaries of life and death. Usually, scientists consider death as the irreversible cessation of the functioning of
A team of scientists presented a new gravity map of Mars at the Europlanet Science Congress 2024. The map shows the presence of dense, large-scale structures beneath Mars’ long-vanished ocean and that mantle processes are affecting Olympus Mons, the largest volcano in the Solar System. The new map and analysis
In the early 2000s, Estonia was modernizing rapidly, tottering residues of Soviet influence. it Was ambitiously turning into one digital society with innovations such as E-Governance and online voting. And, of course, Skype was born, the company that would start the small Baltic country’s journey to becoming a start-up powerhouse
Have you ever walked into a room and forgotten why you walked in, or were ready to speak but suddenly realized you had no idea what to say? of the human brain it normally balances countless inputs, thoughts, and actions, but sometimes it seems to cycle. So what actually happens
Forget anatomy or physiology: Many of the medical students returning to the classroom this month are taking courses that focus more on social justice and diversity. That’s my conclusion in a new study that analyzes curricula at medical schools across the country. Future doctors are spending more time on divisive

For more than 70 years, scientists have searched for evidence of intelligent aliens by hunting for radio signals – interstellar messages beamed billions of miles across space. But for Harvard astrophysicist Avi Loeb, the search for extraterrestrial intelligence it starts much closer to home: In Earth’s oceans. In the summer
As the fall semester progresses, exciting discoveries continue to emerge around the world. This week’s highlights include a paint that makes mouse skin “transparent,” a super-precise nuclear-powered clock, new insights into the role of cholesterol in heart disease, and mushroom-controlled robots. Transparent mice provide non-invasive monitoring of live animals Mice
