Phys.org / More than 120 molecular species found in giant cloud near Milky Way's center
Astronomers have discovered a second interstellar cloud near the center of the Milky Way that is extraordinarily rich in complex molecules, including several molecules associated with prebiotic chemistry. The newly studied ...
Phys.org / Permafrost melt could cost $261 billion in infrastructure damages, study suggests
A new study provides insight into the economic impact of melting permafrost on Arctic communities. Permafrost is ground that permanently remains below freezing for at least two consecutive years. Permafrost covers about 24% ...
Phys.org / BESIII sets world's most stringent direct limit on Lambda hyperon electric dipole moment
The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Tech Xplore / Improved method for producing sustainable hydrogen offers a surprising side benefit
Producing hydrogen is essential for some of the world's biggest industrial and agricultural needs, but it also comes with a steep environmental cost: Most hydrogen made today is generated through processes that release large ...
Phys.org / Heat has a memory—and a new theoretical framework can track it
Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...
Medical Xpress / Three psychedelic drugs affect the brain differently, brain scans in rats suggest
In recent years, psychedelic drugs have attracted growing interest as potential treatments for conditions including depression, anxiety and addiction. Although these drugs are often considered one group, researchers from ...
Phys.org / When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
Phys.org / Ancient DNA suggests western farming reached Gansu without mass migration
A multidisciplinary study has answered key questions about how agricultural practices diffused into ancient Gansu from Eurasia, as well as described population movements and burial practices in the Gansu region thousands ...
Medical Xpress / How meal timing programs the liver's daily rhythms
Deep inside the brain, a master clock synchronizes thousands of molecular clocks scattered throughout the body, and together, they anticipate signals such as the rising sun, the coming night and the daily rhythms of life. ...
Phys.org / Rising species numbers on Europe's mountaintops may mask increasing losses of high-elevation plant specialists
Decades of warming have relaxed cold-temperature constraints on mountain plant distribution and increased species numbers on mountaintops. An international research team led by scientists from the University of Vienna, together ...
