Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, University of Siena, Italy, and University of Szeged, Hungary, reveals a more surprising reality, where success can depend less on competition and more on cooperation.

Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations and also uncovered the underlying biological signals that make the test effective.

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, report researchers at Institute of Science Tokyo, Japan.

Hepatic encephalopathy (HE) is a neurologic complication of advanced liver disease, causing impaired functioning, reduced quality of life (QOL), and increased hospitalisation and mortality.

How does the brain make sense of what we see, hear, and feel—and transform these separate signals into a coherent perception of the world?

Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests.

Doctors use ketamine on patients as general anesthesia before surgery. They also prescribe it in low doses for pain management, and more recently, it's been used for treatment-resistant depression where other drugs have failed.

A new study led by researchers at The University of Texas MD Anderson Cancer Center has identified a way to reshape the gut microbiome that can enhance the delivery of certain chemotherapies to tumors, offering a potential strategy to make nanoparticle-based cancer drugs more effective.

Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth.

As parasites become increasingly resistant to existing drugs, researchers at the University of California, Riverside are working to develop a new generation of treatments for two serious infectious diseases: malaria and babesiosis.

A world-first scabies control program has drastically reduced cases of the highly contagious parasitic skin disease in Solomon Islands and Fiji, according to a new study.

An overactive immune response in the brain may play a role in Dravet Syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers.

Mouse liver cells are not a suitable host for hepatitis E viruses. The Virology department in Bochum has discovered why.

Cardiomyopathies are a group of mostly hereditary, rare heart diseases in which the structure of the heart muscle tissue is impaired.

Researchers have developed a new artificial intelligence-based method that could significantly improve the detection and classification of brain tumors from MRI scans, achieving higher accuracy than conventional diagnostic systems.

A clinical trial led by researchers at CU Anschutz has found that oral semaglutide, a medication widely used for diabetes and weight loss, reduces heavy drinking in adults with Alcohol Use Disorder (AUD).

Women who reach menopause before age 40 face a meaningfully higher risk of developing high blood pressure than those who go through menopause after age 45, according to a new study of more than 107,000 women.

Cardiovascular disease is becoming increasingly common in young people aged 20 to 29, according to the World Health Organization, due to the rise in metabolic conditions such as obesity, hypertension, hyperlipidemia, and diabetes among young populations worldwide.

A gene editing tool designed to precisely rewrite the gene that causes Huntington's disease reduced toxic protein fragments and symptoms associated with the disease in mice, researchers at the University of Illinois Urbana-Champaign report.

Nearly 23 million Americans with blood pressure 130/80 mm Hg or higher may be eligible for blood-pressure-lowering medications based on the 2025 American Heart Association/American College of Cardiology guideline, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed scientific journal of the American Heart Association.
