Phys.org / Under pressure: How a deep-sea protein adapts to an extreme environment

Life in the deep sea is under immense pressure—literally. Such extreme conditions can disrupt the delicate structures of proteins essential to life. Yet somehow, the proteins in deep-sea creatures remain functional. This ...

Phys.org / 'CRISPR-Combo' system speeds regeneration of hard-to-breed perennial crops

Editing a plant's genes is only half the battle. Before a new, improved trait can ever reach a farmer's field, scientists must be able to grow a whole plant from just a few edited cells—a process that can be slow, unreliable ...

Phys.org / Tightly guided atoms could enable low-power quantum navigation when GPS fails

Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall ...

Phys.org / Water isotopes reveal early drought signals in Central Amazon rainfall

The historic droughts of 2023 and 2024 in the Amazon reduced river flows and altered the region's rainfall composition. Daily monitoring in Manaus, the capital of the Brazilian state of Amazonas, revealed these changes through ...

Phys.org / How sex with multiple mates can help save species from extinction

Allowing females to mate with multiple males, rather than just one, could help make species more resistant to extinction, University of East Anglia research shows. A new study reveals that when females have multiple males ...

Phys.org / Ultrathin silicon structures can tune mid-IR light in billionths of a second

Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...

Phys.org / A cellular threshold can determine whether herpesvirus becomes active or lies dormant

During the COVID-19 pandemic, we wore masks and kept 2 meters (6.6 feet) apart in an effort to reduce the spread of the tiny droplets we release into the air with every breath, conversation or cough. The main goal was to ...

Phys.org / From flower to fruit: A tug-of-war between growing tissues

Unlike an animal cell, a plant cell can't crawl or migrate. It's locked inside a rigid wall, cemented to its neighbors for life. A cell born at the center of a young fruit will still be there when that fruit ripens.
