How brain cells manage long distance genetic instructions

Scientists found that messenger RNA (mRNA) molecules that carry genetic instructions to the far reaches of neurons in the brain tend to cluster together mostly because they are abundant, not because they move in coordinated groups.

Novel AI tool not only identifies genetic mutations but also predicts the type of disease

Scientists at the Icahn School of Medicine at Mount Sinai have developed a novel artificial intelligence tool that not only identifies disease-causing genetic mutations but also predicts the type of disease those mutations may trigger.

Two compounds sourced from cannabis show promising anti-cancer effects

In the future, scientists could use drugs made from cannabis to fight ovarian cancer. A team of scientists testing the effects of two chemical compounds sourced from cannabis on ovarian cancer cells have found that both show promising anti-cancer effects.

Gut bacteria mimicry can accelerate the progression of multiple sclerosis

If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system.

A new trial investigates whether the MIND diet can be scaled for obesity management

This study protocol outlines a 12-week randomized trial testing whether a MIND diet intervention is feasible, acceptable, and sustainable for adults with obesity in Sweden. It will generate preliminary evidence on adherence, mental well-being, and gut microbiota changes to inform larger efficacy trials.

E-cigarette use is linked to higher heart attack risk, especially in former smokers

his systematic review and meta-analysis examined whether electronic cigarette use is associated with myocardial infarction and stroke, synthesizing evidence from 12 observational studies. The analysis found higher odds of myocardial infarction among e-cigarette users, particularly former smokers, while no significant associations were observed among exclusive never-smokers.

Metabolic syndrome affects nearly four in ten US adults as rates climb in older and Black populations

A large NHANES analysis found that nearly four in ten US adults met criteria for metabolic syndrome between 2013 and 2023, with no statistically significant change in overall prevalence. However, prevalence rose significantly among adults aged 60 years and older and among non-Hispanic Black individuals, alongside a significant non-linear increase in hypertriglyceridemia.

Swapping high-carb snacks for tree nuts cuts food cravings in young adults at metabolic risk

Daily replacement of typical high-carbohydrate snacks with mixed tree nuts for 16 weeks reduced cravings for sweets and fast foods in young adults with early metabolic syndrome risk. This dietary swap improved overall diet quality, measured by the Healthy Eating Index, without increasing body weight or altering short-term glycaemic markers.

Researchers develop powerful tools for microbiome research advancement

The microscopic organisms that fill our bodies, soils, oceans and atmosphere play essential roles in human health and the planet's ecosystems. Yet even with modern DNA sequencing, figuring out what these microbes are and how they are related to one another remains extremely difficult.

Hypertrophic chondrocytes play a crucial role in bone growth and repair

Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into bone-building cells or osteoblasts, and the formation of new blood vessels to supply the newly formed bone tissue.

Cryo-EM reveals NPFFR1 activation and guides novel ligand design

This study investigates the molecular mechanisms underlying ligand recognition, subtype selectivity, and activation of neuropeptide FF receptor 1 (NPFFR1)-a Gi/o-coupled receptor that responds to endogenous RF-amide peptides (RFRP-3 from pro-NPFFB, NPFF from pro-NPFFA) and regulates physiological processes like opioid function, pain, and energy homeostasis.

Single-cell RNA-seq reveals FBLN7's role in adipose tissue fibrosis

Fibrosis, resulting from excess extracellular matrix (ECM) deposition, is a feature of adipose tissue (AT) dysfunction and obesity-related insulin resistance.

External signals control oncolytic bacteria for precise cancer therapy delivery

Engineered oncolytic bacteria have emerged as a promising therapeutic platform for precision cancer treatment, offering tumor-specific colonization, immune activation, and controllable therapeutic delivery. This review summarizes recent advances in the design and application of synthetic biological strategies that enhance bacterial precision, safety, and efficacy in tumor therapy.

New research reveals the impact of DNA-histone cross-links on genome stability

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within nucleosomes, yet their structural and functional consequences remain poorly understood due to their instability and low natural abundance.

Bioluminescent tool illuminates single-cell activity in living brains

A decade ago, a group of scientists had the literally brilliant idea to use bioluminescent light to visualize brain activity.

Virus shells use asymmetry to control RNA release and infection

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that helps them infect their hosts.

SN101 iPSC-derived therapy relieves chronic pain and preserves joints

SereNeuro Therapeutics, a preclinical biotechnology company developing non-opioid pain therapies, unveiled new data today on a novel approach to chronic pain management and joint tissue preservation.

Over-contracted gut muscles drive gastrointestinal symptoms in myotonic dystrophy

Myotonic dystrophy type 1 (DM1) is the most common form of adult-onset muscular dystrophy, affecting about 1 in 8,000 people. While it is well known for causing muscle weakness and stiffness, DM1 also affects other organs, including the brain, heart and gastrointestinal (GI) tract.

Young tanning bed users show accelerated genetic aging in the skin

Tanning bed users are known to have a higher risk of skin cancer, but for the first time researchers have found that young indoor tanners undergo genetic changes that can lead to more mutations in their skin cells than people twice their age.
