Phys.org / Photonic time crystals unlock ultrafast control of light in the terahertz range
An international team of researchers from École Polytechnique, Collège de France and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal ...
Phys.org / Moonquakes could reveal ice buried beneath lunar south polar craters
Finding water on the moon may only be a matter of detecting the right vibrations.
Medical Xpress / This amino acid may help the body fight tumors and viral infections
The amino acid arginine helps keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes. It's produced by our bodies and found in common high-protein foods. Low levels ...
Medical Xpress / Less sugar early in life may reduce the risk of Alzheimer's
Sugar restriction during the first 1,000 days after conception may significantly reduce a person's risk of developing Alzheimer's by up to 46%. Those are the findings of a new study published in the journal npj Aging that ...
Phys.org / Homing in on the X-ray sky with eROSITA's second data release
The German eROSITA consortium (eROSITA-DE), which includes the University of Bonn and is led by the Max Planck Institute for Extraterrestrial Physics (MPE), has released its second major public data set, the "eROSITA Data ...
Phys.org / Diamond's newfound defect may tame vibrations that hinder quantum light sources
Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have discovered a new type of quantum light emitter in diamonds that could help overcome a number of challenges ...
Phys.org / Waste CO₂ converts into graphite through a newly observed two-step process
Graphite, the carbon core of a humble No. 2 pencil, is also an essential component in technologies such as batteries, smartphones, laptops and industrial power equipment. Today, nearly all of this critical mineral must be ...
Phys.org / Non-monogamy may reduce jealousy overall, but feeling less desirable can still strain relationships
Comparing yourself with your partner is more common than you'd think. Psychologists even have a term for it: mate value discrepancy (MVD), which is the gap between how attractive, smart or successful each partner feels compared ...
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Phys.org / Shark finning regulations have not significantly changed global trade, new analysis finds
Much like caviar, shark fins are a luxury product and delicacy in parts of the world. And like wild caviar, demand for shark fins has posed an incredible threat to species that can't reproduce quickly enough to keep up.
Phys.org / What this western Pennsylvania '90s Pizza Hut reveals about nostalgia
A Pizza Hut in southwest Pennsylvania was recently highlighted for preserving its retro 1990s appearance, even as hundreds of other locations have closed across the United States.
Medical Xpress / Microglia reveal sex-specific brain recovery mechanism after ketamine anesthesia
During ketamine anesthesia, the brain's nerve cells fall silent—as consciousness returns, they begin to reconnect. For the first time, researchers at the Institute of Science and Technology Austria (ISTA) have shown that ...
