Nanoscale solutions with small size differences can be separated by membranes with identical pores—if they have enough opportunity to try. Credit: Argonne National Laboratory. Imagine a close basketball game that comes down to the last shot. The probability of the ball going through the ring may be quite low, but it would increase dramatically if … Read more
In a historic moment for fusion energy, new research shows that the heat of plasma fusion is spread more evenly in tokamak reactors, suggesting new ways to improve reactor efficiency and overall lifespan while reducing the potential for damage. New findings from researchers with the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), … Read more
Researchers have identified a prehistoric marine reptile found in 1935 as a thalattosaur, not a coristodere, using CT scans and a new specimen.

Same-sex sexual behavior has been observed in many non-human species around the world. It’s now a widely recognized phenomenon, but a new study suggests there’s a stark discrepancy between how common the behavior is and how often it’s reported. According to this work, researchers often see same-sex sexual behavior in the mammals they study, but … Read more
For hundreds of thousands of years, the woolly mammoth thrived on Earth, measuring its majestic stride across frozen streams. Then, something happened. The earth changed. And in an extremely short time, the mammoths (Mammuthus primigenius) became extinct, the last of them extinguished 4000 years ago, on the remote Wrangel Island in the cold Arctic north. … Read more
