New hypothesis links internal fat biology to heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFpEF) appears to develop as a result of changes in the biology of a person's internal fat tissue, according to the Adipokine Hypothesis, a new way of understanding how fat may impact the heart.

Scientists discover molecular brake that limits T cell attack on tumors

In a discovery that could expand the array of current cancer immunotherapy treatments, scientists at Harvard Medical School have identified a new molecular brake that hinders the ability of T cells to attack tumors.

Babies fed blueberries show fewer allergy symptoms and boosted immune balance

Daily blueberry powder given to infants during complementary feeding modestly influenced allergic symptom resolution and shaped immune biomarker–microbiota associations. Findings suggest early diet may play a role in immune development, though results are preliminary and exploratory.

How plant compounds could target Alzheimer’s disease from multiple angles

This review highlights how dietary polyphenols modulate Alzheimer’s disease biology through antioxidant, anti-inflammatory, and multi-target mechanisms, supported by in-silico docking analyses. Despite promise, challenges in bioavailability and brain delivery remain key hurdles to clinical translation.

Ultra-processed foods affect sperm quality and metabolism even without extra calories

A controlled crossover trial in Cell Metabolism found that ultra-processed foods increase weight, fat mass, LDL:HDL cholesterol, and alter reproductive hormones in men, with some effects independent of calorie load. These diets also showed trends toward reduced sperm motility, shifts in pollutants, and transient inflammatory responses, highlighting risks beyond excess calories.

Updated guidelines aim to standardize valvular heart disease care across Europe

Updated ESC/EACTS Guidelines, being published today at ESC Congress 2025, aim to improve the way that patients with valvular heart disease are diagnosed and treated, responding to robust new evidence that suggests some newer and less invasive treatments could be offered more widely and consistently to patients.

New ESC guidelines introduce unified approach to improve myocarditis and pericarditis care

New ESC Guidelines to improve the diagnosis and care of patients with myocarditis and pericarditis, have been published today at ESC Congress 2025.

ESC releases new guidance on lipid management to reduce cardiovascular risk

New ESC/EAS Focused Update to Guidelines, about how best to manage lipid levels in patients to reduce cardiovascular risk, recommends the use of new cardiovascular risk predication algorithms. The update was published today at ESC Congress 2025.

New ESC guidelines prioritize women's autonomy in high-risk pregnancies

Updated ESC Guidelines, published today at ESC Congress 2025, put a focus on a woman's autonomy in making her own reproductive choices by promoting a transparent dialogue and shared decision-making for pregnancies that are high-risk for an adverse maternal and/or fetal event.

Discovery of mitochondrial microprotein opens path to obesity and aging therapies

Like bees breathing life into gardens, providing pollen and making flowers blossom, little cellular machines called mitochondria breathe life into our bodies, buzzing with energy as they produce the fuel that powers each of our cells.

New mouse models reveal mechanisms of RP59 retinal degeneration

Retinitis pigmentosa retinal degeneration is caused by a family of hereditary mutations in nearly 100 genes that slowly lead to blindness over years or decades.

Transcription factors SP5 and SP8 regulate primary cilia formation in embryos

Some might say it looks like a finger. Others might see a worm. Scientists in the field often liken it to an antenna.

KAIST researchers develop universal technology to restore altered gene networks

Previously, research on controlling gene networks has been carried out based on a single stimulus-response of cells. More recently, studies have been proposed to precisely analyze complex gene networks to identify control targets.

Alzheimer’s research uncovers a new therapeutic pathway for the memory-robbing malady

The gut contains the largest collection of immune cells in the body. New research at the Buck Institute shows that some of those immune cells travel along the brain/gut axis in a mouse model of Alzheimer's disease (AD) providing a potential new therapeutic pathway for the memory-robbing malady.

Male and female bovine embryos show distinct development paths

Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization.

Hormonal birth control influences emotion and memory in women

Hormonal birth control is a fact of life for millions of women. In the U.S. alone, more than 60 million women of reproductive age have used contraceptives according to the Centers for Disease Control and Prevention, most often to prevent pregnancy but also to manage conditions such as endometriosis, polycystic ovary syndrome and irregular cycles.
