Learn the surprising culprit limiting the abundance of Earth’s largest land animals
2025-12-09
Humans live in a world abundant in salt, but this everyday seasoning is a luxury for wild herbivores, and it’s far from clear how these animals get enough.
A new study published today in Nature Ecology and Evolution and authored by Northern Arizona University researchers and collaborators found the density and distribution of Earth’s largest land animals, including elephants, giraffes and rhinos, appear to be limited by this kitchen essential. There are only a few areas ...
Study reveals new ways the brain regulates communication between neurons
2025-12-09
WASHINGTON – A new finding from researchers at Georgetown University Medical Center shows that the learning process of associating cues with rewards can be altered by increased or decreased activity of a specific protein in the brain. Knowing when to respond positively to cues that result in beneficial outcomes or rewards vs. ignoring cues that result in bad habits, such as smoking addiction, is an essential part of learned behaviors.
“Our ability to link certain cues or stimuli ...
Research reveals new hybrid state of matter where solids meet liquids
2025-12-09
Researchers have discovered that not all atoms in a liquid are in motion and that some remain stationary regardless of the temperature, significantly impacting the solidification process, including the formation of an unusual state of matter—a corralled supercooled liquid.
The formation of solids is essential in various natural processes, including mineralisation, ice formation, and the folding of protein fibrils. It also plays a significant role in technological applications such as pharmacy and industries ...
Researchers develop a new computational tool to understand how genetic interactions impact human traits
2025-12-09
A new study has developed a powerful computational method that can detect how genes interact with each other to influence complex traits in humans at a scale previously impossible. The new method was applied to massive datasets that pair individual genomes and traits to find evidence for such interactions. The findings, published in Nature Genetics, show that a person's genetic background can substantially modify how individual genetic variants affect their traits.
Why it matters
Understanding how genes interact to influence complex traits, such as Body Mass Index or total ...
Elephants, giraffes and rhinos go where the salt is
2025-12-09
Herbivores require a steady intake of sodium to keep their metabolism running smoothly. This is why farm animals have long been given salt or mineral licks. Animals in the wild, however, need to get their salt from sources in their habitats. In some areas, plants and other natural sources of salt provide sufficient sodium, while in others sodium levels are scarce. These differences can influence where certain species settle or how far they will migrate to find natural salt licks.
A new study conducted in collaboration with the University ...
Cancer loses its sense of time to avoid stress responses
2025-12-09
When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example DNA damage or chromosomal instability. That’s why our cells come with an innate ability to tell the time, with a stress response known as the mitotic stopwatch pathway activating after prolonged mitosis, and triggering cell cycle arrest, or even cell death. Now, researchers at the Okinawa Institute of Science and Technology (OIST) have found that certain cancers can ‘lose their sense of time’ to avoid cellular stress responses, revealing new insights that could shape future anti-cancer therapeutics.
The research published in Nature Communications ...
The twisted nanotubes that tell a story
2025-12-09
Magnonics is an emerging engineering subfield that targets high-speed, high-efficiency information encoding without the energy loss that burdens electronics. This energy loss occurs when electrons flowing through a circuit generate heat, but magnonic systems don’t involve any electron flow at all.
Instead, an external magnetic field is applied to a magnet, upsetting the magnetic orientation (or ‘spin’) of the magnet’s electrons. This upset enables a tailored collective excitation called a spin wave (magnon), which travels through ...
Flaring black hole whips up ultra-fast winds
2025-12-09
Leading X-ray space telescopes XMM-Newton and XRISM have spotted a never-seen-before blast from a supermassive black hole. In a matter of hours, the gravitational monster whipped up powerful winds, flinging material out into space at eye-watering speeds of
60 000 km per second.
The gigantic black hole lurks within NGC 3783, a beautiful spiral galaxy imaged recently by the NASA/ESA Hubble Space Telescope. Astronomers spotted a bright X-ray flare erupt from the black hole before swiftly fading away. As it faded, fast winds emerged, raging at one-fifth of the speed of light.
“We’ve not watched a black ...
Study explores the link between newspaper preference and attitudes towards autism
2025-12-09
A new study from City St George’s, University of London has found that people’s newspaper reading habits are a reliable predictor of their attitudes towards autism, even when many other factors such as age, education, political views and personal experiences are taken into account.
The research, published in the journal Autism, reveals that around 10% of the differences in automatic, unconscious bias were linked to what newspapers people read. People who read right-leaning tabloid papers more ...
Artificial turf in the Nordic climate – a question of sustainability
2025-12-09
Artificial turf football pitches are better than natural turf from a sustainability perspective – at least as long as the artificial turf material is recycled and the natural turf is cut using fossil fuel-powered lawn mowers. This is demonstrated by researchers at Linköping University in a new study comparing the environmental impact of the different pitches with the help of life cycle analyses.
“The Nordic climate is tough on football pitches and there isn’t much research on the subject. But there is a great deal of interest from the municipalities as regards sustainability and weighing artificial turf against natural ...

A research team has developed an electrocatalyst that helps turn nitrate--a common pollutant found in groundwater and agricultural runoff--into ammonia under far milder conditions.
Details of their findings were published in the journal Advanced Functional Materials on November 4, 2025.
"Our new catalyst has two main benefits: first, it reduces the emissions linked to fertilizer and chemical manufacturing, ...
Common institutional ownership linked to less aggressive business strategies in Chinese firms
2025-12-09
Background and Motivation
In recent years, the rise of common institutional ownership—where large institutional investors hold significant shares in multiple competing firms within the same industry—has sparked intense debate among scholars and regulators. While some argue it fosters information sharing and improves governance, others warn it may reduce competition and encourage collusion. Despite growing attention, little research has examined how this ownership structure affects overall business strategy. This study investigates whether common institutional ownership makes companies more or less aggressive in ...
Energy and regional factors drive carbon price volatility in China’s emissions trading markets
2025-12-09
Background and Motivation
China’s national carbon market has grown rapidly in recent years, emerging as one of the world’s largest Emissions Trading Systems (ETS). Carbon price volatility not only affects market stability and pricing credibility but also influences corporate investment and emissions strategies. While prior research has identified various factors affecting carbon price fluctuations, most studies focus on a narrow set of variables and rarely compare broader potential drivers across regions. This leaves a gap in understanding which factors are truly critical in explaining volatility ...

Adaptive Kalman filter boosts BDS-3 navigation accuracy in challenging environments
2025-12-09
Precise Point Positioning (PPP) is widely used for high-accuracy navigation, but broadcast ephemeris from the BDS-3 system still suffers from hourly discontinuities that degrade real-time performance. This study introduces a new PPP strategy that integrates a covariance-adaptive Kalman filter to compensate for sudden orbit and clock jumps during each ephemeris update. By incorporating systematic parameters and dynamically scaling process noise, the algorithm better captures unexpected changes in satellite signals. Tests using one week of static global data and a 10-hour marine kinematic dataset show significant gains in accuracy, demonstrating that the proposed ...
Home-based monitoring could transform care for patients receiving T-cell redirecting therapies

Listening to the 'whispers' of electrons and crystals: A quantum discovery
2025-12-09
A researcher at the Department of Physics at Tohoku University has uncovered a surprising quantum phenomenon hidden inside ordinary crystals: the strength of interactions between electrons and lattice vibrations - known as phonons - is not continuous, but quantized. Even more remarkably, this strength is universally linked to one of physics' most iconic numbers: the fine-structure constant.
What makes this dimensionless number (α ≈ 1/137) so iconic is its ability to explain electromagnetic interactions, ...
