Jackdaw chicks learn about predators by listening to adults, new research shows. Scientists played recordings of predator calls to chicks in their nests – and paired the sounds with either adult jackdaw “alarm” calls or “contact” calls that indicate no danger. Chicks that heard predator sounds paired with alarm calls learned to fear the predator – becoming more vigilant on hearing that sound again – while chicks that heard contact calls did not. The study, by researchers at the University ...

The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research. An Adelaide University survey of more than 600 South Australians during the peak of the 2025 bloom found high levels of ‘eco-anxiety’ – distress linked to environmental damage – with many participants reporting persistent worry, sadness and feelings of helplessness. The findings have recently been published in the Journal of Environmental ...

A research team led by Prof. Seunguk Song from the Department of Energy Science at Sungkyunkwan University (SKKU), in collaboration with the Institute for Basic Science (IBS), the University of Pennsylvania, and the U.S. Air Force Research Laboratory, has published a comprehensive technical roadmap for two-dimensional (2D) Indium Selenides (InSe)—a key material for next-generation low-power and quantum computing.

A new Cochrane review has found that sucrose can help with pain relief in newborn babies during common hospital procedures, such as venepuncture. This involves drawing blood with a needle, typically for testing. Newborns, especially preterm infants in neonatal intensive care units (NICUs), undergo numerous painful procedures. Because of their immature pain regulation, they can experience these procedures intensely. Preventing and treating procedural pain in hospitalised newborns is important, as repeated untreated pain has been associated with poorer physical ...

Pollen exposure is linked to poorer exam results taken at the end of secondary (high) school (matriculation), with the effects especially noticeable in subjects involving maths, including physics and chemistry, finds research published online in the Journal of Epidemiology & Community Health.   Recognition is needed of the adverse effects of fluctuations in pollen levels on academic performance and the potential impact on a student’s future prospects, conclude the researchers.   Allergic rhinitis, caused by an allergic reaction to ...

Sleeping for 7 hours and 18 minutes every night may be the sweet spot for warding off the risk of insulin resistance—the precursor to type 2 diabetes—suggests a large observational study published in the open access journal BMJ Open Diabetes Research & Care.   But weekend catch-up sleep is associated with a heightened risk of impaired glucose metabolism in those who sleep beyond the optimal threshold every night, the findings indicate.   Previously published research shows that sleep duration is strongly associated with the risk of insulin resistance, diabetes, and ...

Around 6 deaths a year are linked to clubbing in the UK, finds a 15 year retrospective study published online in Emergency Medicine Journal.   Physical assault, including stabbings and head trauma, or too much ecstasy (MDMA) are the primary causes, the findings indicate.   UK nightclubs attract close to 100 million visitors every year and boast a revenue of just under £1 billion. Risky behaviours while clubbing are common, but current evidence on deaths associated with nightclubs is limited to small case series or isolated critical incidents, with no national data, ...

The Covid pandemic disrupted children’s ability to self-regulate - according to new research from the University of East Anglia. A new study reveals that the pandemic hampered children’s ability to regulate their behaviour, stay focused and adapt to new situations - skills known collectively as executive functions. The greatest impact was seen among pupils who were in reception when the first lockdowns began - a crucial stage when youngsters normally learn to socialise, follow routines and navigate the busy world of the classroom. These children showed less growth in their self-regulatory and cognitive flexibility scores ...

Embargoed copy of the research paper available on request Scientists have analysed more than 40 years of astronomical data to uncover evidence that the Sun’s internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings today (London - 00.01hrs on 4 March) in Monthly Notices of the Royal Astronomical Society, researchers from the University of Birmingham and Yale University reveal that even small differences in solar magnetic activity produce detectable changes inside the Sun. Every 11 years, the Sun goes through a cycle of magnetic activity and is at its calmest during ‘solar ...

According to the model, among all vegetation types, urban trees make the greatest contribution to offsetting carbon dioxide emissions in cities. On some summer days, their absorption can cover the emissions from Munich's urban traffic and even exceed them at times. Because soil respiration exceeds photosynthesis, grassy areas release more carbon dioxide than they bind and are therefore considered a source of CO₂ on an annual basis. Jia Chen, professor of environmental sensing and modeling, and her doctoral student Junwei Li conducted biospheric field measurements in urban parks from April 2024 to February 2025, to validate their model results. Trees as CO₂ sinks, grasslands ...

Scripps Institution of Oceanography at the University of California San Diego has received a $15 million grant from the Fund for Science and Technology (FFST). This support will expand observational capabilities into parts of the ocean where data has historically been sparse or nonexistent. The resulting insights will help scientists understand how the ocean is changing and what those changes mean for the planet. “Scripps Institution of Oceanography at UC San Diego is pushing boundaries for exploration and discovery across the global ...

OKLAHOMA CITY – For the millions of people living with lupus – a chronic autoimmune disease that can damage the kidneys, brain and other vital organs – treatment options remain limited and often come with serious side effects. A $1.7 million grant from the National Institutes of Health will allow a University of Oklahoma researcher to continue investigating a protein that may help explain why the disease develops and how it might be treated more precisely. Carol Webb, Ph.D., a professor at the OU College of Medicine, has spent her career studying the protein ARID3a. Her research has shown that people with lupus ...

A new study published in Biochar presents a practical and regulation-compliant design for producing biochar on farms that could dramatically reduce greenhouse gas emissions from agriculture while permanently removing carbon dioxide from the atmosphere. Agriculture contributes around 12 percent of the United Kingdom’s total greenhouse gas emissions, with manure management alone responsible for nearly 10 percent of the sector’s emissions. At the same time, large volumes of crop residues such as straw are often underutilized, creating missed opportunities for climate mitigation. Researchers from the University ...

A new scientific review reveals how residues from traditional Chinese medicine production can be transformed into high performance biochar materials capable of removing toxic pollutants from water and soil. The work highlights a promising pathway to convert large volumes of herbal waste into valuable environmental solutions. As the traditional Chinese medicine industry continues to expand, so does the generation of herbal residues. These materials are typically discarded through landfilling, stacking, or incineration, creating environmental burdens and wasting potentially useful resources. At the same ...

Researchers have developed a novel engineered biochar that can simultaneously immobilize arsenic and cadmium in contaminated water and agricultural soils, offering a promising new strategy for addressing two of the world’s most dangerous toxic elements. The study, recently published in Agricultural Ecology and Environment, introduces a sulfur-ferrihydrite-modified biochar designed to tackle the complex challenge of co-contamination by arsenic and cadmium. These pollutants frequently occur together in agricultural regions impacted by mining, industrial emissions, and long-term fertilizer use, posing serious ...

NEW YORK, March 3, 2026 — A new scientific study led by paleontologist Stephen Chester, an Anthropology professor at the CUNY Graduate Center and Brooklyn College, is shedding fresh light on how the earliest known primate relatives evolved and spread across North America after the extinction of the dinosaurs. The research—published as the cover article in the Journal of Vertebrate Paleontology—was conducted in collaboration with scientists from the Denver Museum of Nature & Science. It focuses on Purgatorius, a small, tree-dwelling mammal that lived about 66 million years ago and is considered the earliest known relative of all primates, ...

GAINESVILLE, Fla. — For years, treating gum disease has meant scraping away plaque, cutting out damaged tissue or turning to antibiotics that kill bacteria indiscriminately. While newer therapies can regenerate lost tissue, doctors still lack a precise way to stop the infection without harming the mouth’s healthy microbiome. New research from the University of Florida College of Dentistry offers a breakthrough. Researchers have discovered that the primary bacterium driving gum disease carries an internal “genetic brake” that controls its ...

If Canadian jurisdictions mandated warning labels on alcohol and minimum pricing tied to the number of standard drinks in a container, it could prevent hundreds of cancer diagnoses and deaths, according to a new study led by University of Victoria’s Canadian Institute for Substance Use Research (CISUR). The research, published in Lancet Public Health, set out to see how different alcohol policy scenarios could potentially reduce the number of alcohol-related cancers in Canada. The researchers looked at five scenarios: two involving setting price minimums tied to standard drinks in a container — also known as minimum unit pricing—with prices set at $1.75 and $2.00 per ...

Highlights: A preliminary study has found higher levels of air pollution in New Jersey from the 2023 Canadian wildfires were associated with a higher rate of stroke and more severe strokes. During heavy wildfire smoke days, researchers found more people had strokes and those strokes tended to be more severe. The study does not prove that wildfires cause or worsen stroke. It only shows an association. Exposure to higher levels of ozone was associated with a higher incidence of stroke and more bleeding strokes. Exposure to higher levels of particulate matter ...

Understanding how cells are organized and how their molecular components interact in a coordinated and cooperative manner is a central goal of modern life sciences. To answer these questions, researchers need to observe many structures inside the same cell at once and map how they are arranged and interact. This requires “multiplexed super-resolution microscopy” – an advanced imaging approach that reveals cellular details far beyond the limits of conventional light microscopes. However, existing methods are often technically demanding, difficult to reproduce, and not well suited for fragile biological ...

The editorial, “Fruit-Rich Dietary Pattern Improves Endothelial Function: Implications for Food Is Medicine,” is a commentary on the study “Effects of Increasing Total Fruit Intake With Avocado and Mango on Endothelial ...

SAN FRANCISCO—For people living with human immunodeficiency virus (HIV), life-saving antiretroviral therapy keeps their HIV-infected immune cells from making new copies of the virus, preventing illness and transmission. Historically, these infected cells have been known as the “latent” HIV reservoir—implying that the HIV within the infected cells is completely inactive. “But notion that the entirety of the HIV reservoir is latent is actually a misleading description, because some reservoir cells can still be quite active,” says Nadia Roan, PhD, senior investigator at Gladstone ...

Could the deepest parts of the brain hold some of the secrets of sleep that still remain elusive to science? A team from Hackensack Meridian Health and its Center for Discovery and Innovation (CDI) have produced a new in-depth study penetrating into the brain, finding that during the deepest sleep, breathing patterns and brain activity become more independent from one another - unlike lighter sleep or quiet wakefulness. The study was published in The Journal of Neuroscience in January, with the team led by CDI author Bon-Mi Gu, Ph.D., also of the Hackensack Meridian School of Medicine. The research team includes Kolsoum ...
