With an artist's touch and 150 years of anatomical data at his di ...read more
A 2,000-year-old Roman scroll, scorched beyond repair, has miraculously been unfurled with the help of X-ray scanning and artificial intelligence.

PHerc. 172 is the latest remnant of the extensive papyri collection to be digitally opened, reviving lost his ...read more
Rat infestations are increasing all around the world, and scientists suggest that climate change may be to blame. Publishing their results in a recent Science Advances article, a team of researchers analyzed rat populations in 16 cities from around the world, including New York, Boston, and Washington, D.C. Their analysis — one of the first to assess rat populations at such scale — revealed that the cities that saw bigger bumps in temperatures were also the cities that saw bigger bumps in ra ...read more

However, just because many marsupials live in Australia doesn’t mean they’re always thriving.

According to the team, this could be a big leap ...read more
