Phys.org / Tardigrades reveal extreme heat-blocking survival trick while in tun state

Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including ...

Phys.org / 'Shoot for the moon?' Aim a bit lower, researchers say

How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University ...

Phys.org / Diamond quantum sensor could reveal elusive altermagnets

For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but ...

Phys.org / Topological states emerge in quantum Hall-superconductor devices with multiple channels

Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development ...

Phys.org / Predator-triggered orange tails may help tadpoles survive by redirecting deadly bites

Bright colors in animals are beautiful but often considered risky because they are more obvious to predators. However, conspicuous colors can also serve defensively, signaling toxicity or even luring predators away from more ...

Phys.org / Plants hit the brakes on immunity to survive viral infections

When viruses invade a plant, you might expect an all-out immune war. But new research published in Science shows that, much like in humans, too strong an immune response can actually do more harm than good.
