As climate change accelerates, the world is experiencing more frequent extreme weather events and rising temperatures. This is driving up the demand for cooling to make cities liveable, especially in fast-growing megacities with populations exceeding 10 million. While cooling is essential, it also creates a challenge, as conventional cooling systems consume vast amounts of energy and contribute to carbon emissions, creating a vicious cycle that worsens global warming. To break this cycle, Nanyang Technological University, Singapore (NTU Singapore), Aalborg University and Aarhus University in Denmark have embarked on a new five-year research initiative, supported by US$9.4 ...

Air pollution may be harming children’s eyesight with cleaner air helping to protect and even improve their vision - especially in younger children, a new study reveals. Researchers have discovered that exposure to lower levels of air pollutants - specifically nitrogen dioxide (NO₂) and fine particulate matter (PM2.5) - is associated with how well children can see without glasses. Their findings suggest that reducing exposure to these pollutants could help slow the progression of myopia or short-sightedness - when distant objects appear blurry. The condition is becoming more common in children, especially in East Asia. Publishing their findings ...

Andean glaciers advanced during an acute period of climate change at the end of the last Ice Age, new research has found. An international team of glaciologists, led by Aberystwyth University, made the discovery as part of a new project into tropical glaciers in Peru. The finding challenges long-held assumptions about glacier behaviour during this period. The findings, published in Scientific Reports, shed new light on how glaciers respond to shifting climate patterns and may help improve predictions of future climate impacts. The study focused on the Younger Dryas period, a time of sudden and dramatic climate change that occurred approximately 12,900 ...

A new study, led by federal agencies in collaboration with the University of Colorado Denver, shows that the whitebark pine tree—an iconic, high-elevation tree that stretches from California’s Sierra Nevada through the Cascades and Rockies and into Canada—could lose as much as 80 percent of its habitat to climate change in the next 25 years.   The loss could have a cascade of effects, impacting wildlife and people.  The threatened whitebark pine tree is a crucial food source for squirrels and grizzly bears.

Mindfulness meditation may help people struggling with concurrent depression and Internet gaming disorder, according to a study. Guang-Heng Dong and colleagues treated 59 people with depression and Internet gaming disorder (IGD)—which is characterized by excessive and dysregulated video game playing. About a third of people struggling with IGD also suffer from depression. For some, gaming becomes the only way to feel pleasure in an otherwise painful or colorless world. Of the 59 participants, 27 engaged in progressive muscle relaxation ...

A scaling law relates the expected number of mutants to the total population size of cells in a spatially constrained but growing population, which could help clinicians predict when cancers or bacterial infections might develop resistance to treatment. Given a small number of cells in a population subject to a strong fitness pressure, such as a drug intended to kill the cells, mutations are likely to arise. However, it is difficult to predict when those mutations might arise and become common in ...

Foreign exchange (FX) is often described as the world’s deepest and most liquid marketplace, but beneath the headline numbers lies a complex microstructure that shapes how prices form, how liquidity concentrates, and how risk truly behaves across time. At its core, forex is a decentralized, quote-driven market where tiered participants—interbank dealers, non-bank liquidity providers, prime brokers, hedge funds, corporates, and retail aggregators—interact across electronic communication networks and single-dealer platforms. Price discovery unfolds through a constant negotiation of bid–ask quotes, with top-of-book spreads reflecting not only raw competition among market makers but also inventory constraints, latency advantages, and anticipated information flow.

Aviation accounts for approximately 12% of global carbon dioxide emissions. With intensifying climate change and environmental issues, the aviation industry is searching for greener propulsion systems. For unmanned aerial vehicles (UAVs), which have wide applications in military, logistics, and agriculture, research has turned towards hydrogen propulsion systems. Hydrogen is a clean fuel that produces only water during combustion, representing a promising alternative to conventional fossil fuels. However, hydrogen has low volumetric energy density, meaning larger volumes are required to produce the same energy as conventional ...

CHAMPAIGN, Ill. — Illinois once harbored more than 8 million acres of wetlands. By the 1980s, all but 1.2 million wetland acres had been lost, filled in for development or drained to make way for agriculture. Now, thanks to a 2023 Supreme Court decision, roughly 72% of the remaining 981,000 acres of Illinois wetlands are no longer protected by the federal Clean Water Act, putting communities at risk of losing the flood control, groundwater recharge, water purification and natural habitat these wetlands provide, researchers report. A patchwork of state and county-level wetland regulations offer some protection ...

For decades, it was thought that while the brain orchestrated male sexual behaviour – arousal, courtship, and copulation – the spinal cord merely executed the final act: ejaculation. But a study from the Champalimaud Foundation (CF) challenges that tidy division. It reveals that a key spinal circuit is not only involved in ejaculation but also in arousal and shaping the choreography of sex, adding a surprising new dimension to our understanding of sexual behaviour in mammals. “The spinal cord isn’t just a passive relay station executing brain commands”, says Susana Lima, Principal Investigator of CF’s ...

Previously unseen documents show how a poet performed a major ghostwriting job on the autobiography of the two British pioneers behind the world’s first “test-tube baby”, so that the book used emotional storytelling to aid public acceptance of a controversial medical technology. A Matter of Life, coauthored in 1980 by geneticist Robert Edwards – who spent much of his career at Cambridge and went on to win the Nobel Prize – and gynaecologist Patrick Steptoe, tells how their research led to in vitro fertilisation (IVF). The book is the basis ...

ZURICH, SWITZERLAND – September 23, 2025 – A groundbreaking study by the Global Association of Applied Behavioural Scientists (GAABS) has uncovered a troubling disconnect between professionals' confidence in their decision-making abilities and their actual preparedness. While 91% of experienced professionals believe they have above-average decision-making skills, nearly half (45%) lack structured decision habits when making important workplace decisions. The research, representing GAABS' first major empirical study, surveyed 105 professionals across multiple sectors and revealed widespread ...

By Diana Setterberg, MSU News Service BOZEMAN – About 95 million years ago, a juvenile crocodyliform nicknamed Elton lived in what is now southwest Montana at the edge of the Western Interior Seaway.  Measuring no more than 2 feet long from nose to tip of tail, young Elton was about the size of a big lizard, according to Montana State University professor of paleontology David Varricchio. Had it lived to be full grown, Elton would have measured no longer than 3 feet, far smaller than most members of the Neosuchia clade to which it and its distant relatives belong. ...

Science has confirmed what sports lovers have always known from experience: exercise is good for the brain. It increases blood flow, inhibits stress hormones, and stimulates the release of ‘feel good’ endorphins. One way by which exercise is thought to yield these benefits on the brain is through a chain of processes that ultimately results in the release of the hormone BDNF. Produced by the liver, brain, skeletal muscle, and fat tissue, BDNF is known to promote the growth, survival, and maintenance of nerve cells. Previous studies have suggested that the starting signal for this physiological chain is a high level in the blood ...

Routine blood samples, such as those taken daily at any hospital and tracked over time, could help predict the severity of an injury and even provide insights into mortality after spinal cord damage, according to a recent University of Waterloo study.    The research team utilized advanced analytics and machine learning, a type of artificial intelligence, to assess whether routine blood tests could serve as early warning signs for spinal cord injury patient outcomes.    More than 20 million people worldwide were affected by spinal cord injury in 2019, with 930,000 new cases ...
