Phys.org / Newly discovered microbes challenge assumptions about methane production in the environment

It's been known for nearly a century that swarms of single-celled organisms thrive by consuming chemicals from their environments and expelling methane gas as a byproduct. In 2024, researchers in the laboratory of Roland ...

Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine

Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...

Phys.org / Possible 'superkilonova' exploded not once but twice

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of explosion—the kilonova—occurs ...

Phys.org / Organic materials conduct ions in solids as easily as in liquids thanks to flexible sidechains

Normally, when liquids solidify, their molecules become locked in place, making it much harder for ions to move and leading to a steep decrease in ionic conductivity. Now, scientists have synthesized a new class of materials, ...

Phys.org / Are talented youth nurtured the wrong way? Top performers develop differently than assumed, says study

Traditional research into giftedness and expertise assumes that the key factors to develop outstanding achievements are early performance (e.g., in a school subject, sport, or in concerts) and corresponding abilities (e.g., ...
