The way women use energy while running is fundamentally different from men

What makes something alive? We simply don't know, but synthetic biologists are a step closer to providing an answer thanks to SpudCell, the most sophisticated attempt at creating an artificial life form yet

A heat wave over the Fourth of July weekend could put millions at risk of heat-related illnesses. Here’s what to do to stay safe—and why you don’t just need to drink lots of water

Chat apps, e-mail, and cloud files have become the primary record of how power is exercised. Archivists are trying to preserve them before formats go dark or messages disappear without a trace

NASA’s Transiting Exoplanet Survey Satellite has found two “super-puff” planets in the same system, each one as light as cotton candy.

The post Cotton-Candy Exoplanets: Two for the Price of One! appeared first on Sky & Telescope.

This new group, which is led by Harvard professor Avi Loeb, aims to advise the Trump administration and the U.S. intelligence community, as well as to publish its findings in peer-reviewed journals

The European Space Agency has contracted Spanish company EMXYS for the first CubeSat designed to operate on the surface of an asteroid. Don Quijote is a shoebox-sized spacecraft that will be deployed onto the Apophis asteroid by ESA’s Ramses mission before the asteroid flies by Earth on 13 April 2029.

Building on the remarkable success of the Earth Explorer Aeolus wind mission, the European Space Agency has given Airbus Defence and Space in the UK the authorisation to proceed to begin the development of Aeolus’ successor, Aeolus-2 – which is set to be built to enhance operational weather forecasts.

The breakthrough could reveal previously hidden ancient human activity inside caves acting as “genetic archives”
