Scientists investigating Nazi Germany's secret nuclear program have uncovered evidence that its final experimental reactor was nowhere near as close to working as previously claimed. Analysis of surviving uranium cubes and wartime documents reveals that Germany lacked the enormous quantities of uranium and heavy water needed to make its reactor operational.

Yale scientists have uncovered how the stress hormone cortisol helps the brain turn emotional experiences into stronger, longer-lasting memories. The discovery reveals that stress can reshape communication between brain networks involved in emotion and memory, potentially explaining why certain moments are so difficult to forget.
Scientists have discovered that black holes of vastly different sizes appear to launch powerful jets according to the same universal rule. The breakthrough could explain why some black holes suddenly erupt years after devouring a star and help astronomers predict when these spectacular outbursts will happen.
As far-fetched as it may seem, quirks of orbital mechanics could allow hundreds of planets to be packed around a star
Scientists have discovered a remarkable “Pac-Man enzyme” that helps bacteria devour certain types of plastic and may offer new hope in the fight against plastic pollution. Researchers found that several biodegradable plastics completely broke down in soil within about a year, while conventional plastic remained largely unchanged.
Stellar cores called white dwarfs come in an astonishing array of colors, including what scientists say is the first known green star and the reddest star ever found, new research reveals.A white dwarf star is the dense, cooling core that remains after a low- to medium-mass star runs out of fuel. The new study, published Thursday (Oct. 15) in the journal RAS Techniques and Instruments, shows that white dwarfs come in far more colors than their name suggests.White dwarf stars got their moniker because the first known examples glowed in either white or pale blue. The new study, however, suggests that "white" dwarfs also emit visible-light colors like pink, green, cyan, purple and yellow."Most ...
Experts unpack the science of screen addiction and how to build a healthier relationship with technology
Future Arctic winter sea ice is likely to shrink by around 1 million square kilometers (386,000 square miles) more than previously thought, after researchers used clues from a warm period 6,000 years ago to improve the reliability of climate models.
