Zebrafish study links altered neuronal genes to hyperarousal states

The altered presence of tiny fragments of neuronal genes, called microexons, causes hyperarousal in zebrafish. This is the main conclusion of an international study led by the Pompeu Fabra University (UPF) and the Centre for Genomic Regulation (CRG).

Psychologist warns DNA testing kits can bring unexpected risks

DNA testing kits are often gifted for Father's Day, Christmas and special occasions. The idea of learning more about yourself and unearthing some long-forgotten family history is certainly appealing for many, but a psychologist has warned that these presents can come with profound psychological implications.

Study discovers epigenetic mechanism protecting tooth progenitor cells from stress

An epigenetic "mechanostat" has been discovered that protects tooth-forming progenitor cells from mechanical stress and supports lifelong tissue renewal.

AI discovers hidden antibiotic candidates inside disease-causing prions

New antibiotic candidates for drug-resistant bacteria may reside inside prions, mis-folded protein in the brain best known for rare and fatal degenerative brain diseases.

Massage gun use around eyes may cause serious retinal injuries

Using a massage gun on or around the eyes risks major tearing and bruising to the retina-the light sensitive tissue at the back of the eye-doctors warn in the online journal BMJ Case Reports after treating a young man who had used one of these devices.

Sugary chewing gum may temporarily enhance beetroot's blood pressure benefits

For the first time, researchers at King's College London have discovered a link between chewing sugary gum after consuming vegetables high in nitrate, such as beetroot, spinach and kale, on lowering blood pressure.

Fish oil supplements show little benefit for Alzheimer's prevention

Americans spend more than $1 billion annually on fish oil supplements, in part due to purported cognitive benefits from the omega-3 fatty acids they contain, essential nutrients that help form brain cell connections needed for cognition.

Breast milk nutrient boosts long-term immune system development

Trans-vaccenic acid (TVA), the most abundant trans fatty acid found in human breast milk, helps boost immune system development and has long-lasting effects on immune system health in mice, according to a new study by researchers from the University of Chicago.

Scientists discover rotating brain waves that coordinate sensory information

Spiraling waves of neural activity appear and travel in the brain. Scientists hope to learn if these rotating waves on-the-move play a global role in sensing and interpreting internal and external stimuli, in laying down memory, and in managing motor performance.

Cancer-driving genetic mutation does not always cause disease

Researchers have found that a genetic mutation associated with a rare group of blood cancers does not always result in development of the disease.

New CellTrap technology reveals how single immune cells attack brain tumors

Established laboratory tests mainly capture average values across many cells and show, for example, how many cancer cells survive after contact with immune cells.

New mRNA vaccine shrinks neuroblastoma tumors in preclinical study

A new study from RCSI University of Medicine and Health Sciences demonstrates a novel approach in anticancer vaccine development. Results present the first preclinical evidence to show the efficacy of an mRNA vaccine in targeting neuroblastoma, the deadliest childhood cancer.

Epigenetic drugs improve blood vessel health in obesity and diabetes

People with obesity and type 2 diabetes are at high risk of blood vessel damage. This risk depends not only on the genes a person carries, but also on how they are "read".

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.

Aircraft emissions could double air pollution deaths by 2040

Scenario-based modeling projects that aviation-related air pollution could drive a major rise in premature deaths by 2040, mainly through PM2.5 and ozone exposure. The study estimates that aircraft emissions caused 33,900 PM2.5-related deaths and 24,600 ozone-related deaths in 2019, with baseline 2040 deaths projected to more than double.

Gut microbes may help explain why obesity and type 2 diabetes become harder to reverse

This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis.
