Phys.org / Using light to probe fractional charges in a fractional Chern insulator
In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles (i.e., electrons) can prompt the creation of quasiparticles called anyons, which carry only a fraction ...
Phys.org / Long-term radio observations probe a relativistic binary pulsar system
Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information ...
Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way
Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
Phys.org / New species of ancient crocodile named in honor of Welsh school teacher
A new species of crocodylomorph dating to about 215 million years ago has been described from the U.K. It has been called Galahadosuchus jonesi in recognition of David Rhys Jones, a secondary school physics teacher from Ysgol ...
Phys.org / Study of 65,000 college students links 16 hours a week on social media to higher loneliness
More than half of college students are lonely—and those who use social media the most are particularly likely to feel isolated, a study of tens of thousands of 18 to 24-year-olds in the US shows. Just 16 hours a week—two ...
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Phys.org / Offshore wind farms change ocean current patterns, simulations show
By 2050, offshore wind power capacity in the North Sea is set to increase more than tenfold. Researchers at the Helmholtz Center Hereon have analyzed the long-term overall impact of this large number of wind farms on the ...
Phys.org / Amazon rainforest flipped to carbon source during 2023 extreme drought, study shows
The Amazon rainforest is of crucial importance to the Earth's ecosystem, given its capacity to store substantial amounts of carbon in its vegetation. In 2023, the region experienced unusually high temperatures, reaching 1.5°C ...
Phys.org / If alien signals have already reached Earth, why haven't we seen them?
For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically ...
Phys.org / Laser-made surface repels nearly any liquid, even after fivefold stretching
Researchers from North Carolina State University have used laser ablation to create ultra-stretchable, superomniphobic materials without the use of harsh chemical solvents. The materials—which are useful in applications ...
Phys.org / Molecular 'knitting machine' for bacterial capsules mapped in 3D
Most bacteria, including many bacterial pathogens, are surrounded by an outer protective layer of sugar molecules, known as a capsule. This primarily protects the bacteria from environmental influences, but also serves as ...
Phys.org / Q&A: Algorithm achieves near end-to-end genome assembly without ultra-long DNA sequencing
Haoyu Cheng, Ph.D., assistant professor of biomedical informatics and data science at Yale School of Medicine, has developed a new algorithm capable of building complete human genomes using standard laboratory technology. ...
