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

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.

Synchronized infrared lasers control molecular shape changes and expose hidden fingerprint

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind

Could 'Trojan horse'-type microorganisms that exploit symbiotic systems be candidates for

Researchers at National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with researchers from The University of Electro-Communications (UEC) and Akita Prefectural University, have discovered a new insect pathogen that invades the gut symbiotic org

Beyond the 24-hour day: How employee biological clocks and beliefs drive workplace coopera

Employees' biological clocks do more than determine when they reach for coffee; they fundamentally shape how, when and why people help each other at work. A study published in Organizational Behavior and Human Decision Processes introduces the concept of "time-extension self-effi

Feline fleas carry bacteria linked to human disease in South Texas, study finds

As human cases of flea-borne murine typhus continue to occur in South Texas, researchers are working to better understand the role cats and their fleas may play in the disease's transmission cycle.

Bottlenose dolphins in the Adriatic Sea seem to be heavily reliant on trawlers for food

Bottlenose dolphins in the Adriatic Sea are spending much of their time following trawlers to scavenge for food, scientists say. The Adriatic seabed has been plowed by bottom trawlers for decades, resulting in ecosystem damage. Many apex predators are no longer present there. Onl

Two centuries on, experts unlock secrets of Red Sea and Gulf of Aden sailing chart

Experts have unlocked secrets hidden for two hundred years in a beautiful navigational chart made for 18th century seafarers negotiating the Red Sea and Gulf of Aden. The paper scroll is evidence seafaring communities in the region used their own effective system of navigation th

Songs play a greater role than plumage color in limiting bird hybridization, study suggest

When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, chirps or melodious notes defined as "songs"—as wel

Sea turtles diving through the eye of the storm help develop better cyclone forecasts

Every summer, communities across northern Australia brace for the tropical cyclone season. Tropical cyclones draw their power from the warm seas, extracting heat and moisture from ocean water.
