Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the ...

When living cells grow, divide or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But because these heat signals are so vanishingly small, they have traditionally ...

Using an innovative combination of biochemical experiments and ultra-high-resolution microscopy, a research team at Kiel University has solved the long-standing mystery of how the bacterium B. subtilis regulates its cell ...

A research team from Tohoku University and Kyocera Corp. has developed a new magneto-optical material—a nanocomposite magnetic garnet film—that can be deposited directly onto silicon substrates while delivering a magneto-optical ...

An international team of researchers has found plants in the tropics absorb much less carbon dioxide than previous modeling had suggested, which has implications for ecosystem management.

Researchers from the Universitat Autònoma de Barcelona (UAB) have created an open database with 124 carbon-14-dated samples that have made it possible to construct the chronological sequence of 380 sites located in the Aigüestortes ...

Life on Earth has evolved under an uninterrupted rhythm of day and night. While light provides the energy that powers countless molecular processes, periods of darkness often allow biological systems to reorganize, recover ...

Snowfall deep inside East Antarctica has increased in recent decades, and distant ocean temperature changes may be partly responsible. Using long-term climate data and observations from Dome Fuji station, researchers found ...

A new study demonstrates that honeybees can evaluate the reliability of their own communication, actively adjusting the vigor of their "waggle dance" based on the truthfulness of the information they provide. By manipulating ...

A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific Plate dives beneath ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at the Max Planck Institute ...

Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body ...
