Thawing permafrost may unleash industrial pollution across the Arctic
As the frozen ground warms due to climate change, industrial pollutants could flow free from thousands of sites across the Arctic.
- Quantum Physics
A sapphire Schrödinger’s cat shows that quantum effects can scale up
The atoms in a piece of sapphire oscillate in two directions at once, a mimic of the hypothetically dead-and-alive feline.
- Plants
Ultrasound reveals trees’ drought-survival secrets
Scientists used ultrasound sensors and electrical probes to reveal how drought affects the tissues of living trees.
- Planetary Science
Seismic waves crossing Mars’ core reveal details of the Red Planet’s heart
NASA’s InSight lander observed a quake and an impact on the farside of Mars, allowing researchers to measure physical properties of the planet’s core.
- Space
Rocky planets might have been able to form in the early universe
The James Webb telescope spied planet-building material around young stars in a nearby galaxy whose chemical makeup matches that of the early cosmos.
- Materials Science
A vegan leather made of dormant fungi can repair itself
Researchers developed a leather alternative made from dormant fungus that can be reanimated and then regrow when damaged.
- Health & Medicine
A graphene “tattoo” could help hearts keep their beat
A proof-of-concept electronic heart tattoo relies on graphene to act as an ultrathin, flexible pacemaker. In rats, it treated an irregular heartbeat.
- Animals
This elephant peels bananas, but only slightly ripe ones
Pang Pha, an Asian elephant at Zoo Berlin, probably picked up the skill by observing her zookeeper.
- Earth
A massive cavern beneath a West Antarctic glacier is teeming with life
A subglacial river has carved out the cavern beneath the Kamb Ice Stream, a West Antarctic glacier, and may be supplying nutrients necessary for life.
- Life
Comb jellies have a bizarre nervous system unlike any other animal
A 3-D map of the comb jelly “nerve net” reveals fused neurons that lack the space, or synapses, most neurons use to communicate. Did it evolve independently?
- Animals
Northern elephant seals sleep just two hours a day at sea
The marine mammals have truly awesome stamina for staying awake, sleeping only minutes at a time on months-long trips at sea.
- Astronomy
Cosmic antimatter hints at origins of huge bubbles in our galaxy’s center
An excess of positrons in Earth’s vicinity supports the idea that the Fermi bubbles were burped by the Milky Way’s supermassive black hole long ago.
