Mouse sperm thrived despite six years of exposure to space radiation
A space station experiment suggests future deep-space explorers don’t need to worry about passing the effects of space radiation on to their children.
- Physics
Auroras form when electrons from space ride waves in Earth’s magnetic field
New lab results confirm that auroras are triggered by disturbances in Earth’s magnetic field called Alfvén waves.
- Life
Even hard-to-kill tardigrades can’t always survive being shot out of a gun
A recent experiment put tardigrades’ indestructibility to the test by firing the critters at speeds up to 1,000 meters per second.
- Science & Society
A new memoir tells the life story of NASA ‘hidden figure’ Katherine Johnson
"My Remarkable Journey" gives the backstory of NASA mathematician Katherine Johnson, the central character of the 2016 film "Hidden Figures."
- Astronomy
Watch this beautiful, high-resolution simulation of how stars are born
The STARFORGE simulation follows a giant gas cloud as it collapses into new stars, accounting for all the phenomena thought to influence the outcome.
- Climate
‘Tree farts’ contribute about a fifth of greenhouse gases from ghost forests
Greenhouse gases from dead trees play an important role in the overall environmental impact of ghost forests, a new study suggests.
- Space
Planet-forming disks around stars may come preloaded with ingredients for life
Methanol spotted around a hot, young star probably originated in interstellar space, suggesting some chemistry for life may start before stars form.
- Space
A rare glimpse of a star before it went supernova defies expectations
A hydrogen-free supernova in a nearby galaxy appears to have come from an unusual source.
- Earth
Lightning may be an important source of air-cleaning chemicals
Airplane observations show that thunderstorms can directly generate vast quantities of atmosphere-cleansing chemicals called oxidants.
- Space
Stars made of antimatter could lurk in the Milky Way
Fourteen celestial sources of gamma rays provide preliminary hints of matter colliding with “antistars” in our galaxy.
- Physics
X-ray scans explain how the ‘Brazil nut effect’ works
X-ray CT scans of a box of mixed nuts explain the orientations that let large, oblong Brazil nuts rise to the top.
- Paleontology
‘Monkeydactyl’ may be the oldest known creature with opposable thumbs
A newly discovered pterosaur that lived during the Jurassic Period could have used its flexible digits to climb trees like a monkey.
