Scientists discover ancient brain cells that help block distractions

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mice, the animals became unusua

Scientists discover hidden “footprints of death” that may help viruses spread

Scientists have uncovered a surprising new twist in what happens when cells die. As dying cells break apart, they leave behind tiny “footprints of death” packed with newly discovered particles that help guide the immune system to clean up the remains. But researchers found that i

Oysters used as living labs reveal unexpected stability in ocean virus populations

Oysters filter seawater for food. In the process, they concentrate a wide variety of microorganisms from their environment—including bacteria and viruses—into a tiny space.

X-ray snapshots reveal how viral shells change shape as they dry out

When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an international team of researchers has directly observed at the European XFEL how the

Discovery of enzymes that control pores on leaf surfaces could lead to drought-resistant c

A research team at the Ruhr University Bochum Department of Molecular and Cellular Botany, led by Professor Christopher Grefen, has uncovered how plants form the tiny pores on their leaves responsible for gas exchange and water regulation. The scientists identified the two lipid-

Tiny water droplets transmutate aniline into pyridine in ambient and catalyst-free conditi

Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving the reorganization of the carbon-nitrogen bonds wit

Microscale hydrogel fibers could enable imaging inside tiny tissue structures

Researchers have developed light-transmitting hydrogel fibers that are just hundreds of micrometers in diameter. With further development, these soft fibers could one day make it possible to use imaging techniques to detect early breast cancer hidden inside very small breast duct

Earth may have been seeding Venus with life for billions of years

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life t

Tiny raptor, tiny range: GPS tracking reveals pygmy falcons use less than 1 km² to raise n

A new study, published in the Journal of Raptor Research, reveals that Africa's smallest diurnal bird of prey, the pygmy falcon (Polihierax semitorquatus), operates within one of the smallest breeding home ranges ever recorded for a raptor.

How atomic defects can program carbon quantum dots for future light-based technologies

Carbon quantum dots (CQDs) are tiny carbon-based nanomaterials that have attracted increasing attention as environmentally friendly alternatives to conventional heavy-metal quantum dots. They are lightweight, photostable and potentially biocompatible, and their light absorption a

These tiny soil microbes could rescue crops from salty farmland

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilie

This tiny organism contracts 200 times faster than we can blink—here's how

A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ambiguum, uses a calcium-activated protein network in a f
