A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

Abstract: In this work, the design of gradient coils for magnetic resonance imaging (MRI) is studied as a multi-objective optimization (MOP) problem, which is successfully solved by using Pareto ...

A single neutrino detected in 2023 carried more energy than any known cosmic process should be able to produce. Now, physicists propose that the answer may lie in the explosive death of an exotic form ...

The editorial board is a group of opinion journalists whose views are informed by expertise, research, debate and certain longstanding values. It is separate from the newsroom. Thirteen years ago, no ...

Q: I read your article on trees splitting in the cold, and I thought you might like a photo from our tree near Rochester, Minn. This linden splits a little each winter but heals up in the spring. — ...

There are some pretty crazy ways that animals and insects defend themselves. And some insects prioritize the health of the group over their own safety. Although it is a drastic measure, some ants are ...

"If our hypothesized dark charge is true, then we believe there could be a significant population of primordial black holes, which would be consistent with other astrophysical observations, and ...

The expolision of a black hole could explain the origins of a mysterious high-energy neutrino detected in 2023, as well as shedding more light on the mystery of dark matter in the process. In 2023, a ...

Five years ago, mathematicians Dawei Chen and Quentin Gendron were trying to untangle a difficult area of algebraic geometry involving differentials, elements of calculus used to measure distance ...
