Extensive sequencing study finds few links between cancer and microbiome

Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from healthy individuals. The findings, published in eBioMedicine, suggest that a simple, noninvasive hair-based test could one day speed up ALS diagnosis and improve patient care.

A transformative new method for freezing human red blood cells has been developed by researchers from the Universities of Manchester and Leeds.

As obesity in America continues to rise at alarming rates, researchers are finding that diet and exercise are not the only driving factors. A new scientific review from UCLA Health explains how stress, hardship and other social challenges can reshape a person's gut bacteria and brain performance in ways that make it harder to keep weight off.

As protein-rich diets become increasingly popular, a new study suggests that categorizing dietary proteins as either animal- or plant-based fails to effectively capture the source-specific differences in their composition, digestive efficiency and accessibility to the gut microbiota.

A study published in the Journal of Geriatric Oncology highlights a significant gap in the care of older adults with breast cancer: While many face age-related risks that could complicate treatment, a majority decline supportive services even when those risks are identified.

If UC Berkeley's Wenjun Zhang has her way, no one will ever have to brush or floss again.

In the sport of sumo, a bout most commonly ends when one competitor is pushed or thrown outside of a ring of straw bales partially buried in clay. New research shows that using a drug as a blocker to outcompete the SUMO2 protein may be a winning strategy against an aggressive cancer called synovial sarcoma.

According to research conducted by Brazilian scientists, high glucose levels may serve as a biomarker indicating a worse outcome in patients who have experienced their first acute myocardial infarction.

You may have heard of the mind-body connection: the broad concept that thoughts and feelings, especially those related to stress, can influence physical health. Mohamad Alkhouli, M.D., an interventional cardiologist at Mayo Clinic in Rochester, Minnesota, is researching the relationship between the brain and the heart. Each can have a powerful impact on the other, Dr. Alkhouli explains.

A research team from Umeå University, Sweden, in collaboration with Ghent University, Belgium, has made a groundbreaking discovery about how the body's first immune defense, neutrophils, orchestrate the mobilization of zinc to fight microbes.

In many low- and middle-income countries, pediatric cardiologists can't help children with congenital heart conditions because of a critical hurdle. They don't have easy access to advanced diagnostic technology.

The brain depends on a constant supply of oxygen, delivered through an intricate network of tiny blood vessels. Unlike other organs, it has little energy stored and is particularly sensitive to interruptions in blood flow.

New research has uncovered how cerebrospinal fluid dynamics in the brain play an important role in driving the spread of medulloblastoma, the most common malignant brain tumor in children.

Uncemented hip replacement surgery uses implants with roughened surfaces designed to allow the patient's bone to grow directly onto the implant, creating a strong, natural biological bond. Unlike cemented implants, which rely on bone cement that can degrade and fracture, uncemented implants depend on this natural bone integration for long-term stability.

A team of researchers has identified for the first time the mechanism linking a mutation in the Shank3 gene with alterations in social behavior. Using a mouse model carrying this autism-associated mutation, the study shows that vasopressin, a brain hormone essential for social relationships, is not properly released in the lateral septum.

In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new research unveils a blueprint that makes it possible to generate specific kidney cell types on demand—cells that hold immense value for preclinical studies of new therapeutics, congenital kidney diseases, and drug-induced nephrotoxicity.

Compassionate release, or medical parole, describes a legal pathway for people who are incarcerated to be released because of severe illness. Almost every state has policies overseeing the release of individuals who are medically vulnerable, which includes a terminal diagnosis of less than six to 18 months. While these laws are offered as a form of compassion as well as to lessen the burden on the prison system, are they actually working?

People hesitant about getting a COVID vaccine were more likely to consider getting the shot after hearing a myth explained and corrected with facts, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
