Light flips bacterial signaling enzyme between two shapes, unlocking how signals travel

Researchers at the University of Bayreuth and Forschungszentrum Jülich have demonstrated that specific light-sensitive enzymes—so-called sensor histidine kinases (SHKs)—transmit their signal through a light-controlled change in asymmetry. With their new study, the researchers con

AI analysis of data from multiple sensors can improve earthquake detection

One seismometer is often not enough to reliably detect earthquakes or human activity such as underground nuclear tests. Rather, researchers combine readings from seismometers distributed across a small geographic area to gain confidence in their analysis. Artificial intelligence

The broader a fungus's diet, the better it kills insects and helps plants

Many fungi lead triple lives—acting as deadly insect pathogens, decomposers in the soil, and helpful partners living inside and transferring insect-derived nitrogen to plant roots. Scientists have long wondered what allows a single species to pull off these very different roles.

Metallic effect pigments significantly reduce flow-line visibility on glossy plastic surfa

Metallic effects on plastic surfaces have become standard in many industries, from automotive interiors and exteriors to toys and household appliances. However, injection-molded parts with metallic effects suffer from a well-known drawback: visible flow lines that appear as strea

A WRAP for biology's greasiest problem

Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly adapt to changes in their environment.

Instant digital rewards may make hard thinking feel less worthwhile

Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward arrives. Then your phone lights up. One thumb movement, and

Most Europeans see economic growth as essential for a sustainable future

According to a new study by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), most European citizens consider economic growth a necessary condition, rather than an obstacle, for advancing toward a sustainable future. The pa

Prescribed burns may generate over 20% of fine particle pollution in southeastern US

Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. The issue is especially pertinent to the southeastern Un

This spray-on powder can stop life-threatening bleeding in 1 second

A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. It works on deep and irregular injuries where conventional hemostatic products often struggle and remains effective even after years of

How to stop a mouse plague

The scenes are biblical. Tens of thousands of rodents scattering across canola fields, behind sheds, into machinery. River fish with bellies full of mice. Carcasses littering the street, the sidewalk, outside your home. In supermarkets, the inescapable stench of dead and dying mi

Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold

Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.

How signals in the embryo tell cells what to become: A lab's final discovery

Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan Kettering Institute Developmental Biology Chair Kathryn Anderson, Ph.D., is publishing its final study.
