Researchers identified a gene that’s needed for gentle touch to turn painful after an injury. The study uncovers a possible target for treatments to relieve pain caused by skin injuries.

Researchers identified how Bacillus bacteria, which are used in many probiotic formulations, can prevent the growth of harmful Staphylococcus aureus, or “staph,” bacteria.

Women who pushed earlier during labor were as likely to have a vaginal birth as those who delayed, and had fewer complications. The finding may change recommendations made to many women.

In an early trial, a combination of two antibodies suppressed blood levels of HIV for months after treatment in some people.

Researchers engineered a blood pressure sensor that uses ultrasound technology and can be worn as a flexible skin patch.

The discovery of direct neural connections between the gut and the brain in mice could lead to a better understanding of appetite and gut health.

Eliminating old or damaged cells that have stopped dividing reduced signs of brain disease in mice—an important clue for developing treatments for neurodegenerative brain diseases.

Researchers discovered a self-renewing human skeletal stem cell. This study may one day lead to ways to restore bone, cartilage, and supportive tissues for organs.

Primary and metastatic tumors within an individual all likely rely on the same mutations to grow and spread, suggesting that precision treatments could be chosen based on a single sample.

In a mouse model of Alzheimer's disease, access to exercise stimulated the growth of new nerve cells in the brain and reduced memory problems. The findings pave the way for studies in people.

A large clinical trial found that a daily low-dose aspirin doesn’t have the same benefits for healthy older adults as it does for those who’ve had a heart attack or stroke.

Long periods of fasting between meals helped male mice live longer and healthier lives, regardless of the content of their diets.

Researchers stimulated neurons to regrow across scarred spinal tissue in rodents.

Researchers used machine learning to develop a method of predicting which people are at risk of developing an abdominal aneurysm.

Studies show progress in learning to predict which patients are most likely to respond to certain cancer treatments known as immune checkpoint therapies.

A device for supplying oxygen after sudden cardiac arrest outside of a hospital improved survival compared with a more common but invasive and difficult procedure.

Researchers restored some vision in mice with congenital blindness by changing supportive cells in the retina called Müller glia into light-sensing cells.

Teaching first-time mothers how to respond to their infant’s body cues reduced the child’s weight by age 3 compared with a control group.

Notifying clinicians that one of their patients died of an opioid overdose reduced the number and doses of opioid medications prescribed in the following months.

A large study found that, for healthy women, inducing labor at full term rather than waiting for natural labor doesn’t increase the risk of major complications for newborns.

A study of older adults found that long-term exposure to dairy fats wasn’t associated with overall risk of death or death from cardiovascular disease.

Drugs that help repair the nerve cell lining that’s damaged in multiple sclerosis were found to target certain enzymes. The finding could help researchers develop new treatments for multiple sclerosis.

Researchers gained insights into how the waste clearing vessels in the brain change as mice age. The results suggests a possible way to combat the cognitive decline seen in aging and age-related diseases.

Children who grow up in a positive family climate are better equipped to have a healthy romantic relationship as a young adult.

The rhythms of certain metabolic pathways can become shifted by even a few days of being awake at night and asleep during the day. Further research is needed to explore how this finding may play a role in health risks observed in people who work at n...

Researchers developed a way to genetically modify T cells using a jolt of electricity instead of a virus. This method may help expand the medical potential of gene editing.
