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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.

Nvidia chief Jensen Huang urged G20 ministers on Wednesday to build more data centers to support the artificial intelligence revolution and warned that leaders who talk up the technology's dangers risk leaving their countries ...

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 ...

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 ...

RNA-based therapeutics use RNA as a blueprint that enables cells to produce specific proteins—including proteins that can precisely modify genes. For this to work, the RNA must reach the inside of the cell intact. Delivery ...
