The skeletal remains of a female ‘vampire’ were found in a 17th-century Polish graveyard – with a sickle across her neck to prevent her rising from the dead.


The James Webb Space Telescope has just delivered its first direct image of a planet orbiting a distant star.

An extensive study, involving records from more than 116,000 people over the course of 30 years, has found that moderate amounts of physical activity for between 300 and 600 minutes could be the sweet spot when it comes to reducing mortality risk.

Earth’s deepest sources of water may not be as old as we once assumed.

Remains recovered from a cave in the Chinese province of Yunnan more than 10 years ago have finally given up their secrets, with a DNA analysis revealing not just who left them, but ultimately where their ancestors would go.

Astronauts lose decades’ worth of bone mass in space that many do not recover even after a year back on Earth, researchers said Thursday, warning that it could be a “big concern” for future missions to Mars.

Three-dimensional models of astronomical objects can be ridiculously complex. They can range from black holes that light doesn’t even escape to the literal size of the Universe and everything in between.
