Wildfires threaten water quality for up to eight years after they burn

2025-06-23
Years after wildfires burn forests and watersheds, the contaminants left behind continue to poison rivers and streams across the Western U.S. — much longer than scientists estimated.  A new study, published today in Nature Communications Earth & Environment, analyzed water quality in more than 500 watersheds across the Western U.S., and is the first large-scale assessment of post-wildfire quality. The research was led by scientists from the Cooperative Institute for Research in Environmental Science ...

More effective production of “green” hydrogen with new combined material

2025-06-23
The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Linköping University in Sweden. Hydrogen produced from water is a promising renewable energy source – especially if the hydrogen is produced using sunlight. The production of new petrol and diesel cars will be banned in the EU as of 2035. Electric motors are expected to become increasingly common in vehicles – but they are not suitable for all types of transport. “Passenger cars can have a battery, but heavy trucks, ships or aircraft cannot use ...

Study reveals processes important for skin cancer aggressiveness and identifies two classes of drugs that may block them

2025-06-23
Researchers have discovered that the most aggressive melanomas, the deadliest form of skin cancer, overactivate two key processes in mitochondria, the components of cells that provide energy. Blocking these pathways with currently available drugs effectively killed melanoma cells. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. By mapping the proteins expressed in 151 tumor and normal skin samples, investigators found that the most aggressive melanomas hyper-activate the ...

Recycled plastics can affect hormone systems and metabolism

2025-06-23
A single pellet of recycled plastic can contain over 80 different chemicals. A new study with researchers from University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water causing impacts in the hormone systems and lipid metabolism of zebrafish larvae. The plastic pollution crisis has reached global levels, threatening both planetary and human health, and recycling is proposed as one of the solutions to the plastics pollution crisis. However, as plastics contain thousands of chemical additives and other substances that can be toxic, and these are almost ...

How babies are affected by their mother’s age

2025-06-23
Giving birth to a child after 40 is becoming more and more common – but it can entail an increased risk to the child. A new study based on data from over 300,000 births in Sweden shows that children of older mothers are more often born prematurely or with complications, especially when the mother is 45 years of age or older. In large parts of the world, women are having children later and later in life. In Sweden, 4.8% of mothers were 40 years of age or older in 2022. Previous research has shown that older mothers differ from younger mothers in several respects such as having a higher BMI, a higher proportion having utilised assisted ...

‘Closed loop’ learning barriers prevent doctors from using life-saving bedside ultrasound

2025-06-23
Many doctors abandon a potentially life-saving medical scanning technology soon after training, because systemic barriers prevent it from becoming part of their routine practice, a study has found. Point-of-care ultrasound (POCUS) enables doctors to perform rapid bedside scans using a portable device. This can quickly reveal life-threatening problems – including heart failure, fluid in the lungs, or internal bleeding – that can often be treated if identified in time. Although thousands of doctors in the UK are now trained to use POCUS, research, including the new study, shows that many do not continue to use it in practice after completing ...

Simple blood test predicts cognitive decline in Alzheimer's patients, new study shows

2025-06-22
(Helsinki, Finland, Monday, 23 June 2025) Insulin resistance detected by routine triglyceride-glucose (TyG) index can flag people with early Alzheimer’s who are four times more likely to present rapid cognitive decline, according to new research presented at the European Academy of Neurology (EAN) Congress 2025.1 Neurologists at the University of Brescia reviewed records for 315 non-diabetic patients with cognitive deficits, including 200 with biologically confirmed Alzheimer’s disease. All subjects underwent an assessment of insulin resistance using the TyG index and a clinical follow-up of 3 years. When patients ...

Antimicrobial resistance genes hitch rides on imported seafood

2025-06-22
Highlights: Resistance to colistin, a potent antibiotic, is on the rise. In 2016, researchers discovered that colistin resistance could be transferred laterally among microbes. Researchers have isolated genes that confer colistin resistance from imported seafood purchased from markets in Atlanta, Ga. The findings suggest imported seafood could promote the spread of transmissible colistin resistance.  Los Angeles, Calif.—Colistin is a potent, last-resort antibiotic, used only to treat people ...

New way to find “aged” cells marks fresh approach for research into ageing

2025-06-21
Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a new way of telling “aged” human cells apart from younger ones using electric fields. While key markers have been found for these “senescent” cells, current methods require biochemical “labels” which are difficult to apply and affect the cells themselves, making them difficult to study. The new method is label-free and less damaging. The team aims to diversify the method, extending it to other cell types.   Ageing starts at the cellular level. As we get older, aged or “senescent” cells accumulate in our body. Not only have ...

From blood sugar to brain relief: GLP-1 therapy slashes migraine frequency

2025-06-20
(Helsinki, Finland, Saturday, 21 June 2025) A diabetes medication that lowers brain fluid pressure has cut monthly migraine days by more than half, according to a new study presented today at the European Academy of Neurology (EAN) Congress 2025.1 Researchers at the Headache Centre of the University of Naples “Federico II” gave the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide to 26 adults with obesity and chronic migraine (defined as ≥15 headache days per month). Patients reported an average of 11 fewer headache days per month, while disability scores on the Migraine Disability Assessment Test ...

New method to study catalysts could lead to better batteries

2025-06-20
Scientists and engineers study the atomic interactions that happen on the surface of materials to develop more energy efficient batteries, capacitors, and other devices. But accurately simulating these fundamental interactions requires immense computing power to fully capture the geometrical and chemical intricacies involved, and current methods are just scratching the surface. “Currently it’s prohibitive and there’s no supercomputer in the world that can do an analysis like that,” says Siddharth Deshpande, an assistant professor in the University of Rochester’s Department of Chemical Engineering. “We need clever ways to manage ...

More time with loved ones for cancer patients spared radiation treatment

2025-06-20
For many patients, radioactive iodine treatment after thyroid cancer surgery means side effects like nausea and time in hospital isolated from loved ones. But new clinical trial results from researchers at UCL mean hundreds of thousands of patients worldwide could now safely be spared this treatment. Globally, around 820,000 people are diagnosed with thyroid cancer each year. Compared to most cancers, it affects a high proportion of younger people who are more likely to be parents to young children. It is also three times more common in women than men. The Iodine or Not (IoN) clinical ...

New methods speed diagnosis of rare genetic disease

2025-06-20
NEW YORK, NY (June 20, 2025)—A new laboratory method developed by researchers at Columbia University Vagelos College of Physicians and Surgeons may now help physicians more quickly diagnose patients with suspected genetic disorders of the immune system, many who have been trapped in diagnostic limbo for years.  The researchers, who published their findings June 20 in Cell, applied the method to one rare inborn error of immunity called activated-PI3Kδ syndrome (APDS) and found dozens of additional genetic variations that could cause the syndrome. “Our findings give physicians a resource that can help them rapidly diagnose and treat ...

Genetics of cardiomyopathy risk in cancer survivors differ by age of onset

2025-06-20
(MEMPHIS, Tenn. – June 20, 2025) The relationship between genetic variants and the risk of late-onset cardiomyopathy remains poorly understood in survivors of childhood cancer despite being otherwise well established. Scientists from St. Jude Children’s Research Hospital have helped address this gap, assessing whether variant trends seen in the general population also apply to late-onset cardiomyopathy in five-year survivors of childhood cancer. The work revealed that, as in the general population, common variants in TTNand BAG3 are associated with reduced late-onset cardiomyopathy ...

Autism inpatient collection releases genetic, phenotypic data for more than 1,500 children with autism

2025-06-20
The Simons Foundation Autism Research Initiative (SFARI) has released phenotypic and genetic data from the Autism Inpatient Collection (AIC), a cohort of more than 1,500 youth participants ages 4 to 20 years old who were hospitalized in one of six child psychiatry units in the United States. The AIC, supported by SFARI and the Nancy Lurie Marks Family Foundation, aimed to engage these individuals, many of whom meet recently proposed criteria for ‘profound autism’ (autism characterized by intellectual disability or minimal language that requires high ...

Targeting fusion protein’s role in childhood leukemia produces striking results

2025-06-20
Scientists at St. Jude Children’s Research Hospital and Dana-Farber Cancer Institute today report the identification of a novel combination therapy approach to treat pediatric acute myeloid leukemia (AML). Standard treatment is often ineffective against AML, a cancer that commonly relapses with poor prognosis, particularly when the disease is fueled by fusion proteins involving NUP98. The researchers documented how these fusions drive disease, discovering a protein complex required to express cancer-promoting genes. When they targeted the complex alone or in combination with another anticancer drug, survival significantly ...

Clear understanding of social connections propels strivers up the social ladder

2025-06-20
PROVIDENCE, R.I. [Brown University] — Climbing the social ladder isn’t simply a matter of popularity. Rather, people in positions of influence are particularly adept at forming “maps” of their social connections, which they navigate to become prominent in their social network, new research shows.  It’s like having a “social superpower,” according to study author Oriel FeldmanHall, an associate professor of cognitive and psychological sciences at Brown University who is affiliated with the University’s Carney Institute for Brain Science.  “People vary ...

New research reveals why acute and chronic pain are so different – and what might make pain last

2025-06-20
A new study reveals that when we experience short-term (acute) pain, the brain has a built-in way to dial down pain signals — like pressing the brakes — to keep them from going into overdrive. But in long-term (chronic) pain, this braking system fails, and the pain signals just keep firing. This discovery helps explain why some pain goes away while other pain lingers, and it opens the door to new treatments that could stop pain from becoming chronic in the first place. Why does some pain go away ...

Stable cooling fostered life, rapid warming brought death: scientists use high-resolution fusuline data reveal evolutionary responses to cooling and warming

2025-06-20
The Earth is rapidly warming — but did you know? Similar climate upheavals over 300 million years ago once triggered massive fluctuations in marine life. Recently, a research team led by Prof. Shuzhong Shen of Nanjing University published a major finding in Science Advances, revealing for the first time — through high-precision big data — that during the Late Paleozoic (approximately 340 to 250 million years ago), global cooling promoted rapid evolution and diversification of marine life, while abrupt warming, especially that induced by volcanic eruptions, led to mass extinctions. The focus of the study is an ancient group of single-celled marine organisms ...

New research casts doubt on ancient drying of northern Africa’s climate

2025-06-20
PROVIDENCE, R.I. [Brown University] — A study led by researchers from Brown University finds that rainfall patterns across northern Africa remained largely stable between 3.5 and 2.5 million years ago — a pivotal period in Earth’s climate history when the Northern Hemisphere cooled, and places like Greenland became permanently glaciated. The new findings, published in Science Advances, challenge long-held interpretations of the climate history of northern Africa, which had suggested that the region dried out considerably during this period. The timing coincides with the appearance of the first known member of the genus Homo in the fossil record, leading ...

Study identifies umbilical cord blood biomarkers of early onset sepsis in preterm newborns

2025-06-20
Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and colleagues identified several proteins from the umbilical cord blood of preterm newborns that signal acute systemic inflammation as an immune response to infection, providing objective and noninvasive means to diagnose early onset sepsis. This finding could spare infants from prolonged exposure to unnecessary antibiotics, which leaves them at risk for subsequent serious infections and dysregulation ...

Want better sleep for your tween? Start with their screens

2025-06-20
Toronto, ON - Good sleep is vital for adolescents’ physical health, mental well-being, and academic success — yet many don’t get enough rest. Now, a new study reveals bedtime screen habits may be to blame. Published in Sleep Health, the study provides new insights into tweens’ bedtime screen use, as well as its associations with sleep disturbance and duration. Researchers found that over 70% of tweens had an Internet-connected device in their bedroom, with nearly 25% reporting they were woken up in the past week by notifications. If they woke up in the middle of the night, 28% went on their device before falling back asleep. “Getting ...
