Tech Xplore / New memristor design uses built-in oxygen gradient to bring stability to reinforcement learning
In a recent study published in Nature Communications, researchers created a memristor that uses a built-in oxygen gradient to produce slow, stable conductance changes, enabling a reinforcement learning (RL) algorithm to learn ...
Medical Xpress / Reported 2025 drug overdose 'spike' was an illusion, new study finds
In June 2025, several mainstream media outlets reported a surge in U.S. drug overdose deaths in early 2025 that was based on data from the U.S. Centers for Disease Control and Prevention (CDC).
Medical Xpress / A big step toward safe, reversible male contraception
Cornell scientists have taken a major step toward developing a safe, reversible, long-acting and 100% effective nonhormonal male contraceptive, considered the holy grail of male contraception. A proof-of-principle study in ...
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
Phys.org / Born to roam, built for home: New genomic insights for snapper fisheries
Snapper are central to coastal life across southern Australia, supporting fisheries, local businesses, and regional tourism. New Flinders University research has found that although snapper populations across southern Australia ...
Phys.org / Network analysis reveals mammal food web drivers across Africa
Ecology is often understood as a hyperlocal thing. The ecology of a pond, for instance, is vastly complex, even if the pond is tiny. But learning solely from local ecosystems is a slow and laborious approach that may not ...
Tech Xplore / States are struggling to meet their clean energy goals. Data centers are to blame
Nevada's largest utility says it will need three times the electricity required to power Las Vegas just to handle proposed data centers—and it probably can't do that without fossil fuels.
Phys.org / Phengite identified as key carrier of halogens into Earth's deep mantle
Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are transported into Earth through subduction zones, with some being transported into the deep mantle and ...
Phys.org / Antidepressants build up in winter wastewater, raising risks for fish
Every time we flush the toilet, wastewater containing more than tens of thousands of unknown substances, some of which may be toxic to animals and plants, runs into streams and the marine environment. In a study published ...
Phys.org / A nanoparticle therapy to treat lung cancer and associated muscle wasting at the same time
Researchers at Oregon State University have developed a technique for simultaneously treating lung cancer and a serious muscle-wasting condition that often accompanies it. The study, published in the Journal of Controlled ...
Phys.org / Genetic markers fast-track breeding of seedless muscadine grapes
Using new genetic markers, fruit breeders can now tell whether grapes will be seedless and self-pollinating even years before vines bear fruit. The approach will save time and resources in the pursuit of creating flavorful ...
Phys.org / Five Australian animals that could be extinct by 2050
Some 39 Australian mammals have gone extinct since Australia was colonized in 1788.
