AI rollout in NHS hospitals faces major challenges

Implementing artificial intelligence (AI) into NHS hospitals is far harder than initially anticipated, with complications around governance, contracts, data collection, harmonisation with old IT systems, finding the right AI tools and staff training, finds a major new UK study led by UCL researchers.

Experts warn tiny plastics in arteries may raise heart attack risk

Experts caution that nanoplastics and microplastics may constitute an emerging cardiovascular risk factor, with particles identified in arterial plaques associated with a 4.5-fold increase in major adverse cardiovascular events. Experimental evidence points to inflammation, oxidative stress, and vascular injury as key mechanisms.

Genes play an active role in shaping the gut bacteria, study finds

New research from the University of Sydney's Charles Perkins Centre has found that genes play an active role in shaping the bacteria found in our gut, questioning the idea that gut health is influenced only by diet.

Persistent COVID-19 in the intestines may drive inflammation in cancer patients

New research from the University of Minnesota Medical School is providing important insights into how COVID-19 persists in cancer patients even long after testing positive. The findings were recently published in iScience.

Study shows children inhale more microplastics inside school than outside

Researchers measured airborne microplastics and chemical additives in a Portuguese school near an industrial complex. They found higher levels indoors than outdoors, with children continuously exposed to a complex mix of pollutants.

Chronic insomnia linked to faster cognitive decline and brain changes

People with chronic insomnia may experience faster declines in memory and thinking skills as they age-along with brain changes that can be seen on imaging scans-than people who do not have chronic insomnia, according to a study published in the September 10, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Green tea extract reduces weight and improves glucose control in obese mice

Green tea is an ancient beverage recognized for its medicinal and antioxidant properties. It has been widely studied for its beneficial effects on metabolic diseases, such as obesity and type 2 diabetes.

Targeting telomere damage offers new path to boost cancer immunotherapy

Tumors are stressful places for cancer-fighting immune cells. Low oxygen, high acid levels, and other stressors put strain on mitochondria, the cell's energy factories, leading to T cell exhaustion and poor cancer outcomes.

New method reveals how mitochondrial DNA mutations influence cancer growth

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might affect cancer growth.

Chronic illness death rates decline but pace of progress slows

Death rates from chronic diseases have fallen in four out of five countries around the world in the last decade - but progress has slowed, suggests an analysis led by researchers at Imperial College London and published in The Lancet.

Early parent-focused programs fail to reduce childhood obesity by age two

Existing approaches to parent-focused behavioral programs delivered up to 12 months of age which aim to combat childhood obesity are insufficient to improve body mass index (BMI) at approximately two years of age, according to the largest study to date on the topic published in The Lancet.

GABA identified as key blocker of neural repair in spinal cord injury

Spinal cord injuries caused by external trauma, such as traffic accidents or falls, often lead to the permanent loss of motor and sensory functions.

Breathlessness linked to higher mortality in Malawian hospital patients

Research led by Liverpool School of Tropical Medicine and the Malawi-Liverpool-Wellcome Programme shows that over half of hospital patients with breathlessness had died within a year of admission (51%), as opposed to just 26% of those without the symptom.

Can cannabis use disrupt women’s fertility? New study finds strong evidence

Researchers found that THC, the psychoactive compound in cannabis, alters oocyte gene expression, spindle formation, and chromosome segregation, lowering embryo euploidy rates in IVF. This provides direct human evidence linking cannabis exposure to impaired female fertility outcomes.

Daylight saving time does not increase heart attack risk, study shows

A large U.S. registry study of more than 168,000 patients found that daylight saving time (DST) clock changes did not increase heart attack rates or worsen in-hospital outcomes. The findings suggest that the lost or gained hour is unlikely to trigger acute myocardial infarction in contemporary care.

People with similar autistic traits show greater mutual attraction and neural synchrony

New research has revealed that people with similar levels of autistic traits are more attracted to each other, and their brains synchronize in unique ways during passive and active communication.

Rare ABCA7 gene variants linked to Alzheimer’s risk

A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer's in some of the people who carry it.

Lung tumors rewire immune cells in the bone marrow before they reach cancer sites

Lung tumors don't just evade the immune system. They reshape it at its source. Researchers from the Icahn School of Medicine at Mount Sinai and collaborators report in the September 10 online issue of Nature that tumors rewire immune cells in the bone marrow before they even reach the cancer, suggesting a new target to enhance the durability of current immunotherapy
