Physics
We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Artificial intelligence helped scientists create a new type of battery
It took just 80 hours, rather than decades, to identify a potential new solid electrolyte using a combination of supercomputing and AI.
- Materials Science
A fiber inspired by polar bears traps heat as well as down feathers do
Scientists took a cue from polar bear fur to turn an ultralight insulating material into knittable thread.
- Physics
Here’s the science behind the burbling sound of water being poured
The height of the pour and the thickness of the stream help determine the loudness of the falling water.
- Physics
Here’s how much fruit you can take from a display before it collapses
About 10 percent of the fruit in a tilted market display can be removed before it all crashes down, computer simulations show.
- Earth
STEVE and other aurora-like glows perplex scientists with their complex physics
New views of STEVE from citizen scientists keep raising questions about the atmospheric light show — but computer models may offer some answers.
- Physics
Invisible comet tails of mucus slow sinking flakes of ‘marine snow’
New measurements reveal the gunk that surrounds the particles, an important factor in understanding how the ocean sequesters carbon.
- Quantum Physics
A maverick physicist is building a case for scrapping quantum gravity
To merge quantum physics and general relativity, physicists aim to quantize gravity. But what if gravity isn’t quantum at all?
- Earth
Before ancient Egyptians, nature sculpted sphinxes. Here’s how
Steady winds can carve landforms called yardangs — thought to have inspired the Great Sphinx of Gaza — from featureless blobs, a new study suggests.
- Astronomy
A rare, extremely energetic cosmic ray has mysterious origins
In 1991, physicists spotted a cosmic ray with so much energy it warranted an ‘OMG.’ Now that energetic particle has a new companion.
- Physics
Light, not just heat, might spur water to evaporate
In experiments, light shining on water as much as doubled the evaporation rate expected from heat alone, hinting at a never-before-seen effect.
- Physics
A controversial room-temperature superconductor result has now been retracted
The retraction by Nature is the third for beleaguered physicist Ranga Dias, who still stands by his claim of a room-temperature superconductor.
- Physics
How neutron imaging uncovers hidden secrets of fossils and artifacts
The technique can complement X-ray scanning and other tools to uncover details of dinosaur fossils, mummies and more.
