Uncovering the molecular basis of long COVID brain fog

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune signaling pathway that helps stem cells to regrow new intestinal tissue.

Continuous glucose monitors (CGMs) are wearable technologies that track blood sugar in real time and help patients with type 2 diabetes improve blood sugar control. In 2024, the U.S. Food and Drug Administration approved over-the-counter CGMs for individuals with and without diabetes, but there is limited understanding of how to interpret CGM metrics in individuals who do not have diabetes.

The U.S. Food and Drug Administration has approved Eli Lilly's Inluriyo (imlunestrant), an oral estrogen receptor antagonist, for the treatment of adults with estrogen receptor-positive, human epidermal growth factor receptor 2-negative, ESR1-mutated advanced or metastatic breast cancer whose disease progressed after at least one line of endocrine therapy (ET).

"You still had to prove yourself." "Every cloud has a blue lining!" Which of those sentences are you most likely to remember a few minutes from now? If you guessed the second, you're probably correct.

The importance of all health screenings is that they can detect issues early. Prostate cancer is one of the most common cancers in the world, and the second-leading cause of cancer deaths among men in the U.S.

Three in 5 Americans experience anxiety over world events, family safety, or financial security, according to a recent mental health poll by the American Psychiatric Association. In this edited conversation, clinical psychologist Rachel Zack Ishikawa, who is also an instructor in the Department of Psychiatry at Harvard Medical School, spoke to the Gazette about when anxiety, a normal response to stress, can morph into a mental health disorder, the role of social media in its spread, and how to prevent it from interfering with everyday life.

Georgia spent $54.2 million in less than five years to administer the country's only Medicaid program with work requirements—more than twice as much as it spent to provide health care to enrollees, according to an analysis released earlier this month by the Government Accountability Office.

Two major Australian health insurers, Bupa and Medibank, have started offering genetic testing meant to tell you your likely reaction to certain medications.

As dementia rates continue to rise and many people fear for their own brain health and that of older relatives, interest has grown in finding relatively simple ways to help ward off disease. Professors in the Robert Stempel College of Public Health & Social Work have investigated the relationship of sleep, diet and stress to Alzheimer's. Out of their work come suggestions of potential value to anyone concerned about preventing illness and improving their overall well-being.

Heather Bowers doesn't recall all the details of her first cholesterol screening. It was at a college health fair two decades ago, and even though her numbers came back "borderline high," she responded in a way that many people in their 20s might.

A study led by researchers at the National Cancer Institute-designated Montefiore Einstein Comprehensive Cancer Center (MECCC) has found that mutations in blood-forming cells may explain the increased risk for leukemia and other blood disorders among first responders exposed to the 9/11 World Trade Center (WTC) disaster site and its toxic dust.

Harvard Medical School, Brigham and Women's Hospital, and Dell Medical School researchers report that rising rates of early-onset cancer in the United States may reflect more diagnoses rather than more disease.

Adolescent athletes' cardiovascular system may adapt to increased cardiorespiratory fitness by increasing blood pressure, arterial stiffness and heart growth, a new study shows. The study was conducted in collaboration between the Technical University of Munich and the University of Eastern Finland, and the results were published in the American Journal of Physiology-Heart and Circulatory Physiology.

Everyone knows staying hydrated is important, but new research highlights just how important it is for a less obviously related area of health—sleep.

Changing health habits—like quitting smoking, exercising more, or sticking to prescribed treatments—is difficult but crucial for preventing and managing chronic diseases. Motivational interviewing (MI), a patient-centered counseling method that helps people find their own motivation to change, has proven effective across many health care settings.

McGill University researchers have developed an artificial intelligence tool that can detect previously invisible disease markers inside single cells.

Sometimes, aches and pains get dismissed as a normal part of getting older. In the case of peripheral artery disease, or PAD, those pains can be signs of a serious problem.

Flu season is fast approaching in the northern hemisphere. And a taste-based influenza test could someday have you swapping nasal swabs for chewing gum. A new molecular sensor has been designed to release a thyme flavor when it encounters the influenza virus.
