Older age and low fitness levels are associated with heartbeat abnormalities that increase future cardiovascular risk
2025-08-27
Key take-aways
New research finds that low fitness levels and older age are strong and independent risk factors for heartbeat irregularities, or arrhythmias*, in healthy adults. These arrhythmias were previously thought to be harmless, but are now considered to be an indicator of future cardiovascular risk (1,2)
The results support the introduction of age-based arrhythmia screening in over 50s, to allow for early intervention before symptoms arise to alter the trajectory of disease
There was a particularly strong association between lower aerobic fitness and risk of frequent and complex atrial arrythmias, ...
‘Built for cutting flesh, not resisting acidity’: sharks may be losing deadly teeth to ocean acidification
2025-08-27
Sharks can famously replace their teeth, with new ones always growing as they’re using up the current set. As sharks rely on their teeth to catch prey, this is vital to the survival of one of the oceans’ top predators.
But the ability to regrow teeth might not be enough to ensure they can withstand the pressures of a warming world where oceans are getting more acidic, new research has found. Researchers in Germany examined sharks’ teeth under different ocean acidification scenarios and showed that more acidic oceans lead to more brittle and weaker teeth.
“Shark teeth, despite being composed of highly mineralized phosphates, are still vulnerable to corrosion under ...
Study reveals beneficial effects of diet and exercise on alcohol-related adverse liver health
2025-08-27
Amsterdam, August 27, 2025 – A novel study investigating how physical activity and diet quality interact with different levels and patterns of alcohol consumption shows that healthy eating and increased levels of physical activity significantly lower the risk of alcohol-attributable liver-related mortality. The findings from this comprehensive new study in the Journal of Hepatology, published by Elsevier, use data from a large multi-ethnic US cohort and highlight the importance of considering other lifestyle behaviors when estimating the risk of death from alcohol-related liver disease at a population level.
In the US, more than half (53%) of adults over 18 years of age regularly ...
Making the weight in four years
2025-08-27
Kyoto, Japan -- Periodical cicadas have one of the strangest life cycles in the animal kingdom. The 17-year cicadas spend 99.5% of their lives underground in an undeveloped nymph state, which is the longest strictly regulated juvenile period among insects.
Then in the spring of their 17th year, they simultaneously emerge and the males scream above ground for their four to six week-long adult life. Exactly how these insects are able to control when they mature and emerge has remained a mystery.
The long life cycle of periodical cicadas makes rearing nymphs for study extremely difficult. Recently, however, a collaborative team of researchers from both Japan and the ...

Scientists discovered hopfion crystals – which are flying in spacetime
2025-08-27
An internationally joint research group between Singapore and Japan has unveiled a blueprint for arranging exotic, knot-like patterns of light into repeatable crystals that extend across both space and time. The work lays out how to build and control “hopfion” lattices using structured beams at two different colors, pointing to future systems for dense, robust information processing in photonics.
Hopfions are three-dimensional topological textures whose internal “spin” patterns weave into closed, interlinked loops. They have been observed ...
For bees, diet isn’t one-size-fits-all
2025-08-27
Move over gym rats. Bumble bees are now the true masters of macros.
In the first long-term, community-level field study of wild bumble bee nutrition, a team of ecologists led by Northwestern University and the Chicago Botanic Garden discovered that wild bees aren’t just flitting from flower to flower, collecting pollen at random. Instead, they are strategically targeting flowers that enable them to carefully balance their protein, fat and carbs.
Focusing on pollen consumption, the study revealed that coexisting bee species occupy two distinct nutrient niches. Larger bodied bees with longer tongues prefer pollen that’s ...
How a malaria-fighting breakthrough provides lasting protection
2025-08-27
A relatively new class of insecticide that can be disseminated on something the size of a sheet of paper offers protection for up to a year against mosquitoes that spread malaria, as well as dengue, West Nile, yellow fever, and Zika, UC San Francisco researchers have found.
In a systematic review of more than 25 years of data on some 1.7 million mosquitoes, researchers concluded that this form of repellent — called a “spatial emanator” because it distributes chemicals through the air — can prevent more than ...
Cognitive Behavioural therapy can alter brain structure and boost grey matter volume, study shows
2025-08-27
Psychotherapy leads to measurable changes in brain structure. Researchers at Martin Luther University Halle-Wittenberg (MLU) and the University of Münster have demonstrated this for the first time in a study in “Translational Psychiatry” by using cognitive behavioural therapy. The team analysed the brains of 30 patients suffering from acute depression. After therapy, most of them showed changes in areas responsible for processing emotions. The observed effects are similar to those already known from studies on medication.

2025-08-27
New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London, in partnership with the University of Bath, has found that the reasons why a person chooses to use cannabis can increase their risk of developing paranoia.
The use and potency of cannabis is increasing worldwide, and dependence and cannabis-induced psychosis are also greatly increasing as a result, especially in North America. Two new research papers, both using data from Cannabis & Me - the largest survey of its kind - have identified key risk factors associated ...
Most US neurologists prescribing MS drugs have received pharma industry cash
2025-08-26
Nearly 80% of US neurologists prescribing drugs for multiple sclerosis (MS) received at least one pharma industry payment, with higher volume prescribers more likely to be beneficiaries, finds a 5 year analysis of Medicare database payments, published in the open access journal BMJ Open.
And those in receipt of these payments were more likely to prescribe that company’s drugs, especially if the sums involved were larger, sustained, and recent, the findings indicate.
Because of the lifelong nature of MS, effective therapies are usually continued indefinitely unless a patient’s clinical response changes, explain the researchers. And MS drug prescriptions are ...

Brain’s immune cells key to wiring the adolescent brain
2025-08-26
Making a smoothie, going for an evening walk, or having empathy for a loved one are all examples of executive functions that are controlled by the brain’s frontal cortex. This area of the brain goes through profound change throughout adolescence, and it is during this time that abnormalities in maturing circuits can set the stage for neurodevelopmental disorders, such as schizophrenia and ADHD. Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have discovered that microglia, the brain’s immune cells, ...

MSU study: What defines a life well-lived? Obituaries may have the answers.
2025-08-26
Why this matters:
Obituaries function as time capsules that reflect what people, at any given moment in history, understand to be a life well-lived. By studying how obituaries evolve across time and context, we can gain deeper insight into how societies define a worthy life, express loss and pass on values across generations.
New MSU-led research takes a novel approach to the psychological study of legacy by focusing on how individuals are actually remembered by others instead of how they wish to be remembered.
Legacy motivations influence a range of real-world ...
Wind isn’t the only threat: USF-led scientists urge shift to more informed hurricane scale
2025-08-26
Key takeaways:
Storm surge and rainfall — not wind — cause the majority of hurricane deaths, yet are absent from the current warning system.
Researchers developed and tested the Tropical Cyclone Severity Scale, which incorporates all three hazards and can rate storms up to Category 6.
Study shows people are more likely to correctly identify risks and evacuate when informed using the new scale.
TAMPA, Fla. (Aug. 26, 2025) – Wind alone does not account for all hurricane-related fatalities. Storm surge and rainfall do as well. Yet the current warning system – the Saffir-Simpson Hurricane ...
