Isolated gut microbe drives stronger responses to cancer therapy

The U.S. Food and Drug Administration has issued seven warning letters to companies illegally marketing products containing 7-hydroxymitragynine (7-OH), which is found in trace amounts in kratom.

Tuberculosis (TB) was the leading cause of death in the United States in the 19th and 20th centuries. By 1900, TB—which usually attacks the lungs but can affect almost any part of the body—had killed one in seven people who had ever lived, more than any other illness.

Whether it's a walk by the sea or a breath of fresh air in the park, spending time in nature is widely known to support good health and well-being.

When was the last time you sat down and tried to learn something? How did you approach it? Did you make flashcards for hard-to-remember terms and concepts, ask a friend to quiz you on the subject or simply jump into the deep end with a new project?

Australian births with continuity of obstetric-led care in private hospitals have significantly fewer adverse outcomes and cost less than births in public hospitals with care by multiple health professionals and limited continuity, Monash University-led research has found.

As the age-old proverb rightly states, "You are what you eat." A balanced diet lays the foundation for healthy living and disease prevention. However, a "one-size-fits-all" approach may not work, given the biological, cultural, socioeconomic, and lifestyle differences. Moreover, gender and age can dramatically influence dietary preferences.

Folks seeking relief from low back pain in an ER aren't likely to leave with a prescription for opioids.

GLP-1 weight-loss drugs like Ozempic and Zepbound are so effective it might seem that a person can lose weight without doing anything at all.

GLP-1 weight-loss drugs are changing how people date and connect. In a nationally representative survey of 2,000 single U.S. adults (ages 18 to 91) led by the Kinsey Institute at Indiana University with DatingNews.com, GLP-1 users reported a wide range of physical, social, and psychological shifts they attributed to the drug.

A new study from UC San Francisco challenges the traditional view of how the brain strings sounds together to form words and orchestrates the movements to pronounce them.

Innovative virtual eye clinics in shopping centers could significantly reduce waiting times for routine eye appointments, UCL-led research suggests in a first-of-its-kind study.

A new Yale study has revealed that neurons—the energy-hungry cells that connect and direct activity in the brain—are equipped with "backup batteries" that kick in to keep the brain running during periods of metabolic stress.

Hemorrhagic strokes account for just 13% of the nearly 800,000 strokes that occur in the U.S. each year, yet they are responsible for more than 40% of all stroke-related deaths. These devastating brain bleeds have long lacked standardized surgical treatment protocols, limiting patient recovery options.

A study led by the Universitat Autònoma de Barcelona (UAB) shows that bee venom apitoxin alters the functioning of blood vessels, even at low concentrations. Researchers also identified an important molecular pathway of oxidative stress involved in this effect, which in turn opens the door to exploring its therapeutic potential.

Personalized exercise guidance is needed for people living with chronic lymphocytic leukemia (CLL), the most common type of blood cancer, according to a new study led by the University of Surrey.

Illegal opioids can create substantial harms, but the extent of those harms depends on multiple factors, including the amount consumed. In a new study, researchers assessed whether opioid consumption intensity varies appreciably over time or context. They found that intensity—as opposed to prevalence—of illegal opioid use varies enormously. These findings have implications for drug treatment and policy.

Around 8% of all births in England are preterm. Despite improvements in neonatal care and survival, preterm children still have more difficulties in later life than their peers, including a higher risk of mental health problems, which have not improved in recent decades.

Premature menopause has been described as a life-changing diagnosis with profound physical, psychological, and social consequences. Affected women not only experience the effects of estrogen deficiency, but they also experience the unanticipated loss of reproductive function.
