Tiny blood particles help shuttle a hormone through the body

Researchers at Touro University Nevada have discovered that tiny particles in the blood, called extracellular vesicles (EVs), are a major player in how a group of hormones are shuttled through the body. Physical exercise can stimulate this process.

New insights explain the Treg paradox in colorectal cancer

In most solid tumors, high numbers of regulatory T (Treg) cells are associated with poorer outcomes because they dampen the immune system's ability to fight against a tumor.

Scientists create light-controlled versions of cholesterol

High levels of cholesterol are linked to heart disease, stroke, and many other health problems. However, this complex and vital fatty, water insoluble molecule-a lipid-is found in every cell of the body and is not all bad news. It also regulates crucial processes that science has yet to map.

What drinking kefir really does to your gut and oral microbiome

The impact of kefir on gut and oral microbiomes shows promise, but inconsistent findings and study limitations call for more rigorous scientific investigation.

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.

Engineering muscle stem cells for sustainable cultured meat production

The production of cultured meat depends on the isolation, expansion, and differentiation of animal stem cells into edible tissues. Muscle stem cells, or satellite cells, are central to this process due to their ability to regenerate and form muscle fibers.

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.

UC Irvine receives funding for clinical trial of neural stem cell therapy for Huntington's disease

Leslie M. Thompson, Donald Bren Professor of psychiatry and human behavior as well as neurobiology and behavior at the University of California, Irvine, has received an $11,999,933 grant from the California Institute for Regenerative Medicine for an unprecedented clinical trial of a novel neural stem cell therapy for Huntington's disease.

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.

Human heart organoids enable new therapies for atrial fibrillation

Though an estimated 60 million people around the world have atrial fibrillation, or A-fib, a type of irregular and often fast heartbeat, it's been at least 30 years since any new treatments have been developed.

Early relapse predicts poor survival in mature nodal T-cell lymphoma

Mature nodal T-cell lymphoma is a type of rare and aggressive blood cancer. Limited data make it difficult to identify high-risk patients or tailor treatment strategies, so most patients receive similar care despite differences in disease characteristics and outcomes.
