Phys.org / Broken time-reversal symmetry phase in kagome metals may establish conditions for superconductivity
Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute ...
Phys.org / Modeling nuclear fusion at lightning speed
As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into nuclear fusion research. The hope is that fusion may ultimately provide a virtually limitless source ...
Phys.org / Ordinary enzyme that evolves into 'control switch' reveals tuberculosis weak spot
Researchers at the University of Surrey have identified a protein that acts as a control switch, preventing Mycobacterium tuberculosis from accessing the energy sources it needs to survive. The discovery points to a specific ...
Phys.org / How AI-generated cartoons reshaped Taiwan's 2024 protests
In spring 2024, more than 100,000 people protested in Taiwan's streets. On Threads, a parallel fight was underway.
Phys.org / New findings challenge idea that human bodies simply got bigger and bigger over time in a steady line
The biggest jump in body size among our ancestors happened around 2–2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.
Phys.org / Titan and Pluto exhibit the same mysterious spectral feature—and researchers can't figure out its origin
Researchers are constantly sifting through new spectral data gathered by powerful telescopes, like the James Webb Space Telescope (JWST). Most of the time, when they identify spectral features—specific absorption or emission ...
Phys.org / How languages recycle parts of words to avoid confusion
Many languages recycle words, giving them different meanings. For example, in English, "run" can mean to move quickly but also to manage something, like "run a company." In Spanish, "lengua" is both the word for tongue and ...
Phys.org / Crashing insect populations lead to smaller tree swallows that reproduce less
Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
Phys.org / What made prehistoric communities resilient? Ancient social networks may hold the answer
A new study led by Dr. Ariel Malinsky-Buller of the Hebrew University of Jerusalem challenges long-held assumptions about how prehistoric hunter-gatherers survived in the Southern Caucasus between 57,000 and 27,000 years ...
Phys.org / High-severity fires burn 30 times more acreage than 40 years ago, researchers find
Forest fires now burn 10 times more acreage annually than in 1985, while wildfire severity has gotten even worse. In California, 30 times more acreage burned from high-severity, forest-killing fires, according to new UCLA ...
Phys.org / How thousands of nature's longest sperm squeeze into a tiny fruit fly
When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was viewing the inside of a male fruit fly's sperm storage organ, using a powerful microscope at the CCBScope ...
Phys.org / How oxygen sneaks into a corked wine bottle long before the first pour
The main reason for sealing wine bottles with a cork is to protect the liquid from oxygen. However, it is not an impermeable barrier, and a small amount of air leaks in, which is not always entirely bad news. The gas helps ...
