Phys.org / Trees use a 'muscle' to correct their posture—a newly discovered role for tension wood
A research team from INRAE and the University Clermont Auvergne has shown that trees are capable of correcting a curvature they detect in their stems through a specific biological process. In the study, young trees with bent ...
Medical Xpress / Alcohol-linked cancer's toll extends far beyond the liver, with deaths rising across age groups
Alcohol-attributable cancer deaths in the U.S. doubled between 1990 and 2023, a new study found. The study also revealed that alcohol-linked cancer deaths are not limited to older adults or liver cancer. Among adults ages ...
Medical Xpress / Scientists uncover shared biology behind profound fatigue in five major illnesses
A shared biological mechanism that helps explain chronic exhaustion in conditions including long COVID and PTSD has been identified by researchers at the University of East Anglia and Oxford BioDynamics. The paper, published ...
Phys.org / Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost
Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release ...
Medical Xpress / Brain scans reveal new link between progesterone and women's mood
The influence of the hormone progesterone on mood is well known. Now, researchers from the University of Barcelona have shown how higher levels of progesterone during the menstrual cycle are linked to less distinct patterns ...
Phys.org / Cellular maintenance crew may miss as much as half of certain misfolded proteins
As proteins are made in a cell, they are folded into the 3D structure that allows them to work, but sometimes this process can go wrong. When it does, the misfolded proteins lose some or all of their function and usually ...
Medical Xpress / Boosting indoor light could help support healthy aging in older adults in urban areas
Bright light therapy lamps can improve sleep, activity levels and circadian rhythms among older adults in urban areas who have diminished exposure to natural light, a new study from the University of Surrey reports. Scientists ...
Phys.org / Caterpillar twitches in an ultraquiet chamber help biologists understand how these insects hear without ears
In a quiet summer garden, a caterpillar perches on a branch, munching serenely on leaves. A moment later, it freezes. It senses danger—and just in time. From behind, a wasp approaches, sizing up its prey.
Phys.org / Scientists observe Einstein's gravity in the quantum world
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental ...
Phys.org / Trapped light generates nanoscale magnetization
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...
Phys.org / Copper's oxygen-rich early oxidation layer could inform catalyst design and nuclear waste storage
Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps ...
Phys.org / PACMAN AI framework for controlling fusion systems safely makes key decisions in milliseconds
Inside some fusion energy systems, particles hotter than the core of the sun can become unruly in a few thousandths of a second, far faster than any human operator can react. A new software framework developed by researchers ...
