All Stories by Maria Temming
- 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.
- Science & Society
STEM’s racial, ethnic and gender gaps are still strikingly large
Black and Hispanic professionals remain underrepresented in STEM, while women’s representation varies widely by STEM field, according to a new report.
- Tech
‘Pipe Dreams’ flushes out hope in an unexpected place: the toilet
A new book shows how reimagined toilets will allow humans to use pee and poop as natural resources.
- Earth
A spike in Arctic lightning strikes may be linked to climate change
Global warming may be revving up summer thunderstorms in the Arctic, leading to skyrocketing numbers of lightning strikes.
- Physics
Newly made laser-cooled antimatter could test foundations of modern physics
Physicists have finally used laser cooling to tame unruly antimatter atoms. That could allow new tests of symmetry and Einstein’s theory of gravity.
- Astronomy
A new black hole image reveals the behemoth’s magnetic fields
A new analysis of Event Horizon Telescope data from 2017 brings to light the magnetic fields twisted around the black hole at the core of galaxy M87.
- Space
‘Oumuamua may be a chip knocked off an icy, Pluto-like exoplanet
If the first interstellar visitor were a shard of nitrogen ice, it would explain some of its unusual behavior when it passed through our solar system.
- Earth
Phosphorus for Earth’s earliest life may have been forged by lightning
Lightning strikes can supply one of life’s essential elements, long thought to be delivered by meteorites billions of years ago.
- Space
Most of Mars’ missing water may lurk in its crust
Computer simulations of the fate of Mars’ water may explain why the Red Planet turned into a desert, when so little of its water has escaped into space.
- Physics
A magnetic trap captures elusive ultracold plasma
Pinning plasma within a set of magnetic fields offers physicists a new way to study clean energy, space weather and the inner workings of stars.
