Researchers have trapped and observed individual atoms for what they say is the first time ever. The mechanism is a kind of supercooled atom rodeo, where individual atoms at nearly absolute zero are held in separate compartments before being...
NASA satellite pictures reveal the scale of “widespread melting” observed earlier this month. On February 6, weather station thermometers peaked at 18.3C (65F) degrees – about the same temperature as Los Angles, US, that day. “I haven’t seen melt ponds...
A frozen bird was found on the ground in Siberia in 2018, but it had been there much longer than the latest snowfall. Researchers at the Swedish Museum of Natural History determined that the Ice Age specimen was a horned...

A first cell atlas of the human thymus gland could lead to new immune therapies to treat cancer and autoimmune diseases. Researchers from the Wellcome Sanger Institute, Newcastle University and Ghent University, Belgium, mapped thymus tissue through the human...
How are we able to find things in the dark? And how can we imagine how something feels just by looking at it? It is because our brain is able to store information in such a way that it can...
An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details...
For three years, anthropologist Alan Rogers has attempted to solve an evolutionary puzzle. His research untangles millions of years of human evolution by analyzing DNA strands from ancient human species known as hominins. Like many evolutionary geneticists, Rogers compares...
Ancestors of Neandertals and Denisovans left Africa for Eurasia around 700,000 years ago and then interbred with a Homo population that had exited Africa long before, according to a new genetic study. The finding reveals the oldest known case...
