New research published in the Journal of Applied Ecology, shows long-lived species may suffer greater impacts from predation than was previously thought.

When will 6G be a reality? The race to realize sixth generation (6G) wireless communication systems requires the development of suitable magnetic materials. Scientists from Osaka Metropolitan University and their colleagues have detected an unprecedented collective resonance at high frequencies in a magnetic superstructure called a chiral spin soliton lattice (CSL), revealing CSL-hosting chiral helimagnets as a promising material for 6G technology. The study was published in Physical Review Letters.

Helicobacter pylori (H. pylori), the bacteria that can cause human gastritis, peptic ulcers and stomach cancer, infects about half of the world's population. It is essential to quickly identify the infection and select the right combination of sensitive antibiotics. Current tools, however, are limited, mainly because H. pylori are slow-growing and hard to cultivate.

A collaborative study from UT Southwestern scientists has identified a new function for a protein called TAO2 that appears to be key to inhibiting replication of the influenza virus, which sickens millions of individuals worldwide each year and kills hundreds of thousands. The findings were published in PNAS.

Throughout the middle of the 20th century, phosphorus inputs from detergents and fertilizers degraded the water quality of Switzerland's Lake Geneva, spurring officials to take action to remediate pollution in the 1970s.

The majority of farmers surveyed in Bangladesh, Rwanda and Zambia are willing to pay for visits to CABI-led Plantwise plant clinics, which help diagnose potentially devastating crop pests and diseases as well as ways to mitigate impacts on yields.

With climate change rapidly warming the world's oceans, the future of the Arctic Ocean looks grim. Climate models show that parts of the Arctic that were once covered in ice year-round are warming so quickly that they will be reliably ice-free for months on end in as few as two decades. The Arctic's changing climate will endanger countless species that thrive in sub-zero temperatures, scientists say.

Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue—but these gains are fragile, a new study suggests.

Researchers from Nanjing University and Beihang University in China and the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg, Germany, have produced a new class of exciton with hybrid dimensionality by engineering the properties of layered silicon diphosphide (SiP₂). Their work has been published in Nature Materials.

With the Colorado River's depleted reservoirs continuing to drop to new lows, the federal government has taken the unprecedented step of telling the seven Western states that rely on the river to find ways of drastically cutting the amount of water they take in the next two months.

It was a nightmare fire season that California won't soon forget.

A mountain lion was struck and killed by a vehicle Friday in the Santa Monica Mountains, not far from where her mother was killed in a 2018 crash, the National Park Service said.

Imagine having the knowledge to prevent a catastrophic event from occurring ahead of time. In horse racing, this could be a possibility.

The importance of fog in forest ecosystems has been recognized and debated for centuries. However, the extent to which the leaves of rubber plants can maintain net CO2 assimilation in the fog season is not known.

Many urban gardeners know that adding ingredients like compost and mulch to their soil has great benefits. But it can be difficult to know what to add and why. Researchers at Purdue University gathered scientific evidence about one specific soil addition, leaf mold compost, and how it benefits tomato plants.

With Run 3 of the Large Hadron Collider (LHC) just around the corner, the LHC experiments are still publishing new results based on the previous runs' data. Despite no new discoveries being announced, small deviations from expectations are appearing in a small number of analyses. At the current level, these deviations can still be attributed to random fluctuations in data, but they indicate regions that need to be investigated closely once the new stream of collisions arrives. Below are a few examples... Читать дальше...

An international team of astronomers have for the first time combined the power of 64 radio telescope dishes to detect the faint signatures of neutral hydrogen gas across cosmological scales.

Blood pressure is one of the most important indicators of heart health, but it's tough to frequently and reliably measure outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to give a reading have been the gold standard. But now, researchers at The University of Texas at Austin and Texas A&M University have developed an electronic tattoo that can be worn comfortably on the wrist for hours and deliver continuous blood pressure measurements at an accuracy...

The chiral signature of a fragrance can reveal whether a perfume is genuine or fake. Similarly, the chiral signature of the emissions of a plant can provide information on whether the plant is healthy or sick. Researchers at Johannes Gutenberg University Mainz (JGU) and the Max Planck Institute for Chemistry (MPIC) have developed an innovative approach capable of identifying and monitoring such chiral signatures. Most natural chiral substances are found in two mirror-image forms present in different relative quantities. Читать дальше...

Researchers from Cornell University, Ohio State University, Technical University of Munich, and the Connecticut Agricultural Experiment Station are using synchrotron light to investigate how moisture affects soil carbon—an important ingredient for healthy crops and fertile fields.

In a new study published in Nature Chemical Biology, researchers at Children's Hospital of Philadelphia (CHOP) have revealed the molecular mechanics of a cell-surface molecule that is a potential immunotherapy target. Using sophisticated techniques, including nuclear magnetic resonance (NMR) spectroscopy, the researchers demonstrated the importance of so-called chaperone molecules in stabilizing this target, known as MHC-I-related protein 1 (MR1).

A new Charitable Journalism Project report—Local News Deserts in the UK—examines the effects of the collapse of local news through the eyes of people in seven places across Britain.

The connection start-up entrepreneurs and potential mentors build during their very first "date" plays an important role in determining whether a mentoring relationship develops.

To understand modern racial inequalities, historical context is crucial. That's according to new research from Penn sociologist Regina Baker published in the American Journal of Sociology.

Which antimicrobial resistance genes are present in bacteria, for example in a hospital ward? For laboratories with limited financial resources characterizing bacterial DNA is difficult, as this often requires expensive equipment. Researchers at Chalmers have now developed a method that can detect specific bacterial genes that encode resistance using standard microscopes, which are already used to diagnose tuberculosis in low-income countries.
