Phys.org / More effective, longer-lasting sunscreen made from natural extracts
Scientists from the Laboratory of Dermatological Photobiology of the University of Malaga, in collaboration with Cantabria Labs España, have carried out a study in which, for the first time, they have demonstrated how a natural ...
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 / 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 / A laser inspired by black holes: Extreme physics recreated in the lab
Researchers from Bar-Ilan University have successfully recreated key features of black hole physics in a laboratory setting using an innovative optical system that mimics how black holes behave after violent cosmic events ...
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 / 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, ...
Phys.org / Crabs' iconic sideways walk evolved from common ancestor, study suggests
Researchers have provided new insights into the evolutionary origin of sideways walking in crabs. Their study, published today as a Reviewed Preprint in eLife, presents the largest comparative dataset on crab locomotion to ...
Phys.org / Astronomers precisely date rare brown dwarf companion, offering new test for how these objects cool
Astronomers at the University of Hawaiʻi have precisely measured the age of a nearby sun-like star and its unusual companion, known as a brown dwarf, an object that falls between a planet and a star. The discovery offers ...
Phys.org / Deep-rooted grass stores significantly more carbon, says new study
Soil biologist Eric Slessarev has some advice for conservationists, landscapers, and farmers with fallow fields: Go touch deep-rooted grass. Or better yet, go plant some. Slessarev, an assistant professor of ecology and evolutionary ...
Phys.org / Perovskite quantum dots crack two big barriers, staying stable in polar solvents and growing with atomic precision
Perovskite quantum dots are considered promising materials for LEDs, photocatalysis, and future quantum light sources. Researchers at LMU Munich have managed to master two major hurdles in working with these quantum dots: ...
Phys.org / Birds and monkeys in the Amazon share information via 'internet of the forest'
You might go for a walk in the forest to disconnect from work and calm your nerves after a busy week. The chirping and calls of birds in the canopy above might be exactly what allows you to relax.
Phys.org / A few extra minutes of daily play can strengthen your bond with your dog in four weeks
Playing a little extra with your dog improves the emotional bond between owner and dog, according to a new study from Linköping University. However, training did not give the same results. The study is relevant for all dog ...
