Astrophysicists reach another milestone on their quest to understand the heliosphere...

We can add suggesting and proving mathematical theorems to the long list of what artificial intelligence is capable of: Mathematicians and AI experts have teamed up to demonstrate how machine learning can open up new avenues to explore in the field.

While mathematicians have been using computers to discover patterns for decades, the increasing power of machine learning means that these networks can work through huge swathes of data and identify patterns that haven’t been spotted before.

In a newly published study, a research team used artificial intelligence systems developed by DeepMind, the same company that has been deploying AI to solve tricky biology problems and improve the accuracy of weather forecasts, to unknot some long-standing math problems.

Scientists reveal conditions in early solar system. Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled — and fascinated — by what’s inside. Most meteorites are made of tiny beads of glass that date back to the earliest days of the solar system, before the planets were even formed.

An intense but short-term exposure to cannabis vapor lowered sperm counts and slowed sperm movement, or motility, not only in the directly exposed male mice but also in their sons.

The Washington State University study, published in the journal Toxicological Sciences, builds on other human and animal studies, showing that cannabis can impede male reproductive function. The current study uses more controlled circumstances than human studies, which often have to rely on surveys, and is the first known reproductive study to use vaporized whole cannabis in mice, which is the more common form humans use...
