A new route to electrically controlled helimagnetic structures
Advanced magnetic memory and spintronic devices rely on the ability to control magnetic states using electricity. Today, such technologies work by manipulating relatively simple magnetic structures found in ferromagnets, where all the magnetic moments point the same way. However,
STING protein: Study finds new ways for the body to activate and possibly control inflamma
Understanding inflammation—and, above all, how to regulate it—is one of the great medical challenges of modern medicine. Its role as the first line of defense is crucial. It occurs when the presence of infectious agents triggers an inflammatory response. As well as hindering the

New technique takes the heat out of 3D printing process
Researchers have developed a new 3D printing technique that allows the printing of whole objects while controlling the temperature of the chemical reaction to stabilize the process. Academics in the University of Nottingham's Faculty of Engineering, in collaboration with the Univ

Scientists just debunked a dangerous baby rattlesnake myth
A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more serious bites. The team also unc
Physicists finally build a quantum material predicted more than a decade ago
Physicists finally build a quantum material predicted more than a decade ago
Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature qu

This week, researchers reported finding nanoplastics in Antarctic soils for the first time, suggesting they were delivered via long-range atmospheric transport. A study associates the use of hormonal birth control with the risk of brain tumors. And researchers developed a new dru

A robot that reads bacteria by touch, without staining or chemical labels
Fast identification of bacteria is important in health care, food safety, environmental monitoring and infection control. One of the most common first steps is gram classification, which separates bacteria into gram-positive and gram-negative groups. This information can help gui
New method brings single-particle quality control to nanocrystal manufacturing
New method brings single-particle quality control to nanocrystal manufacturing
Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not yet fully realized their potential. One major reason is t

Plan to restore nature in England by 2030 criticised as ‘completely insufficient’
Plan to restore nature in England by 2030 criticised as ‘completely insufficient’
Critics accuse ministers of failing to take control of nature crisis and leaving it to private landowners to act voluntarilyThe government’s plan to protect and restore nature in England by 2030 has been condemned as “pathetic” and “completely insufficient” in the face of the spi

Random by design: Flickering genes may spend energy to achieve precision
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers of control. A new study involving researchers from the Ins

Study reveals how gas bubbles shaped Kīlauea's 2018 lava flow
The lava that buried entire neighborhoods during the 2018 Kīlauea eruption was composed of nearly 80% gas bubbles near its source. A recent study shows that those bubbles played a central role in controlling how fast and far the lava traveled and that lava flow models need to acc
