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.
