A fresh look at TikTok: Short food videos encourage long-term healthy eating habits in teens

A research team has identified genetic factors that influence the shape of subcortical brain regions—far beyond volume measurements. The results could open up new approaches for the early detection of neurological and mental disorders.

In today's world, we hear a lot about what we should eat: more vegetables, less sugar and salt, and to obtain locally sourced, sustainable, and nutrient-rich food. But there's a fundamental question most people don't think about: How do we actually know what is in our food? The answer lies in food composition databases (FCDBs), which are collections of data about the nutritional content of different foods, from macronutrients like protein and fat, to vitamins, minerals and specialized biomolecules like antioxidants and phytochemicals.

Devices made with cheap strips of paper have outperformed two other testing methods in detecting malaria infection in asymptomatic people in Ghana—a diagnostic advance that could accelerate efforts to eliminate the disease, researchers say.

Thousands of bacterial and other microbial species live in the human gut, supporting healthy digestion, immunity, metabolism and other functions. Precisely how these microbes are protected from immune attack has been unclear, but now a study led by Weill Cornell Medicine investigators has found that this immune "tolerance" to gut microbes depends on an ancient bacterial-sensing protein called STING—normally considered a trigger for inflammation. The surprising result could lead to new treatments for inflammatory bowel disease and other conditions involving gut inflammation.

Researchers at Karolinska Institutet and Lund University in Sweden have identified a new treatment strategy for neuroblastoma, an aggressive form of childhood cancer. By combining two antioxidant enzyme inhibitors, they have converted cancer cells in mice into healthy nerve cells.

In children with undernutrition, increasing weight in a child's first decade of life can lead to significantly taller adults—with no increase in the risk of obesity or high blood pressure later in life, according to a new University of Michigan study.

Did you know that around one in two women in the UK will experience symptoms of pelvic floor dysfunction at some point in their lives? And for women who engage in high-intensity exercise, that figure rises to 63%.

Liver cancer is the sixth most common cancer globally and a leading cause of cancer-related deaths. Accurate segmentation of liver tumors is a crucial step for the management of the disease, but manual segmentation by radiologists is labor-intensive and often results in variations based on expertise.

In a policy statement issued by the American Academy of Pediatrics and published online June 16 in Pediatrics, updated recommendations are presented for providing adolescent patients with contraceptive counseling and methods.

A Virginia Tech study provides new insights about nieces and nephews taking care of aging relatives living with dementia.

An ETH spin-off, Swiss Vascular, has developed anatomically exact silicone models of cerebral vessels. Through this development, researchers will not only reduce the amount of animal experimentation required but also improve the standard of medical training for complex medical procedures.

Exposure to mycotoxins—a broad group of harmful substances produced by mold—during pregnancy may impact placental function, which could result in lower birthweight in humans, according to Rutgers Health researchers.

A major new study has uncovered how everyday financial behaviors—captured in routine banking data—can signal early signs of cognitive decline and financial vulnerability in older adults, up to a decade before formal intervention.

Obesity, diabetes and cardiovascular diseases are increasingly present in the population. Brown adipose tissue has a protective function against these prevalent diseases, as it burns calories and can produce body heat from fat. But as the body ages, the activity of brown adipose tissue decreases. This inactivation of brown adipose tissue—also typical of obese people—remains poorly studied in the scientific literature.

Older couples may want to take a closer look at their drinking habits together.

Mass General Brigham researchers have developed a new AI tool in collaboration with the United States Department of Veterans Affairs (VA) to probe through previously collected CT scans and identify individuals with high coronary artery calcium (CAC) levels that place them at a greater risk for cardiovascular events. Their research, published in NEJM AI, showed the tool called AI-CAC had high accuracy and predictive value for future heart attacks and 10-year mortality. Their findings suggest that implementing such a tool widely may help clinicians assess their patients' cardiovascular risk.

Dr. Allison Rosenthal's experience facing a leukemia diagnosis while in medical school inspired her to pursue a career fighting cancer. It also gave her insight into aspects of life with cancer for people under 40. Now, Dr. Rosenthal is among the leaders of an effort at Mayo Clinic Comprehensive Cancer Center to help younger adults and older teens receive age-appropriate care and support. In this expert alert, Dr. Rosenthal shares three topics that younger people with cancer often want to discuss with their healthcare teams.

Cornell researchers have identified an antibiotic, rifampin, that is 99.9% effective against Salmonella Typhi, the bacterium that causes typhoid fever. Researchers also predict that rifampin will work on other life-threatening diseases like bacterial pneumonia and meningitis.
