Phys.org / How algae helped some life outlast extinction
Earth's largest mass extinction occurred about 252 million years ago, wiping out the majority of marine and terrestrial life, disrupting the global carbon cycle for several hundred thousand years, and earning the title "the ...
Phys.org / Magnetic nanoparticles that successfully navigate complex blood vessels may be ready for clinical trials
Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel. These drugs spread throughout the entire ...
Phys.org / Mechanistic model can predict biological community development across ecosystems
Biological communities are rarely stable. Their composition is constantly changing, depending on the environmental conditions in the respective ecosystems—and sometimes this change is so vast that individual species completely ...
Phys.org / New biosensor technology maps enzyme mystery inside cells
Cornell researchers have developed a powerful new biosensor that reveals, in unprecedented detail, how and where kinases—enzymes that control nearly all cellular processes—turn on and off inside living cells.
Phys.org / Hidden signatures of ancient Rome's master craftsmen revealed
In the hushed light of a museum gallery, Hallie Meredith discovered something intriguing about ancient Roman glasswork hiding in plain sight.
Medical Xpress / LSD microdosing reduces depression scores without major side effects, clinical trial finds
University of Auckland researchers report that an 8-week, twice-weekly LSD microdosing regimen for major depressive disorder was feasible and well-tolerated, with Montgomery-Åsberg Depression Rating Scale (MADRS) scores ...
Medical Xpress / Stinky socks help replace human bait in surveys for river blindness
New research shows that it's possible to end the practice of using people as human bait to catch and test the black flies that spread river blindness (onchocerciasis). The study by international non‐profit Sightsavers in ...
Phys.org / Analysis reveals extensive dog diversity millennia before modern breeding practices
An archaeological study has revealed when domestic dogs first began to show the remarkable diversity that characterizes them today.
Medical Xpress / Quantifying the intensity of emotional response to sound, images and touch through skin conductance
When we listen to a moving piece of music or feel the gentle pulse of a haptic vibration, our bodies react before we consciously register the feeling. The heart may quicken and palms may sweat, resulting in subtle electrical ...
Phys.org / Reactor-grade fusion plasma: First high-precision measurement of potential dynamics
Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to confine plasma at temperatures ...
Phys.org / New pterosaur species discovered in previously overlooked specimen of dinosaur regurgitalite
The area known as the Santana Group in the Araripe Basin in northeastern Brazil has long been an important fossil site, contributing significantly to knowledge of the Cretaceous period. In particular, it has yielded many ...
Phys.org / The hidden impacts of drinking-water treatment on urban streams
Aging lead-pipe drinking water systems, along with the public health measures implemented to reduce their risks, are reshaping the chemistry and health of nearby urban streams. New research from University of Pittsburgh biogeochemists, ...
