Phys.org / Breathing new life into an ancient mystery: Unlocking the trilobite's respiratory secrets
For more than 270 million years, trilobites were among the most successful and diverse creatures on Earth, with over 22,000 known species spanning the Paleozoic Era. Yet, despite their abundance in the fossil record and their ...
Phys.org / Photonic chip generates milliwatt-level UV light, 100 times brighter than before
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique ...
Phys.org / Collagen analysis finds wider prey use by Neanderthals and modern humans
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has taken part in a study published in the International Journal of Osteoarchaeology that provides new insights into subsistence strategies during the ...
Phys.org / Your phone's next speed boost may come from a strange magnetic jump that rewrites how chips handle heat
A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing ...
Phys.org / Before the melt begins, sea stars show hidden immune collapse and tissue failure driving a coastal die-off
Scientists are homing in on a mysterious wasting disease that has killed billions of sea stars along the Pacific coast of North America since 2013. Sea star wasting disease can rapidly wipe out entire populations, leaving ...
Phys.org / New research reveals cell proteins that drive severe viral infections
Researchers at Umeå University have identified two human cell proteins, NUP98 and NUP153, that play a crucial role in how viruses such as tick-borne encephalitis virus (TBEV), West Nile virus, and dengue virus replicate in ...
Phys.org / Plastics found in tomato and wheat crops stunt growth, study finds
A study investigating microplastics (MPs) and nanoplastics (NPs) in agricultural settings has found they reduced plant growth and entered plant tissues through the soil, raising new concerns about food safety and human exposure. ...
Phys.org / What Bronze Age people ate and drank: South Caucasus pottery reveals a surprisingly diverse menu
What culinary practices prevailed in the South Caucasus during the Bronze Age? A new study shows that the cuisine was remarkably diverse. The evidence highlights a multi-ingredient cuisine alongside the central role of dairy ...
Phys.org / Self‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are smaller and structurally simpler ...
Phys.org / Half of America sits in democratic limbo—and that silent middle may decide what breaks next
If you were to ask democracy scholars what they consider the greatest threat to American democracy, you might assume it is voters who support undemocratic practices or policies. But the real answer may surprise you: These ...
Phys.org / Cell membranes may store memories after electrical stimulation
The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, ...
