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 ...

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 ...

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 ...

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 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 new study shows that in 2023, substance use disorders led to nearly $93 billion in lost productivity in the United States from missed work, reduced job performance, inability to work, and lost household productivity. The novel analysis appearing in the American Journal of Preventive Medicine, published by Elsevier, highlights the need for prevention and treatment strategies to reduce harm and costs. “Substance use disorders can impair cognitive and behavioral functioning, resulting in productivity losses,” said the team of investigators from the Centers for Disease Control and Prevention. “While ...

More than half of psychologists experimented with artificial intelligence tools in their practices in the past year, but almost all cite concerns about how the technology may affect their patients and society, according to the American Psychological Association’s 2025 Practitioner Pulse Survey. This annual survey, conducted by APA and its companion organization, APA Services, Inc., was completed by 1,742 psychologists in September 2025. It found that 56% of psychologists reported using AI tools ...

Ammonia fuels agriculture, supports industry, and is increasingly viewed as a key player in future clean-energy systems. Yet producing it is heat and pressure intensive. 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, ...

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 ...

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 ...

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 ...

Patients who receive T-cell redirecting therapies are typically hospitalized for several days after treatment to watch for side effects. Now new research by Fox Chase Cancer Center physicians shows that these patients can safely be monitored at home. The study, presented today at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition, showed that a structured outpatient model significantly reduced the number of days patients spent in the hospital, with no negative outcomes. Fewer Hospital Days, No Safety Compromises “There are multiple benefits to our approach,” ...

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, ...

Quantum technologies from ultrasensitive sensors to next-generation information processors depend on the ability of quantum bits, or qubits, to maintain their delicate quantum states for a sufficiently long time to be useful.  One of the most important measures of this stability is the spin coherence time. Unfortunately, qubits may lose coherence because their environment is “noisy,” for example, due to the presence of nuclear isotopes or other interference that disturbs the qubit. Two-dimensional (2D) materials—or atomically thin sheets—can offer quiet environments for qubits, as their reduced thickness naturally lowers the number of isotopes that interact ...
