Medical Xpress / Low-dose THC keeps breast cancer cells in tumor models from reverting to an aggressive state
Recent discoveries have revealed that breast cancer cells are more flexible than previously thought. Some can change from a differentiated state, when a mature cell has taken on a specific function, back to a more stem-like ...
Medical Xpress / Gut bacteria linked to key brain chemicals in first-of-its-kind human study
The neuroactive potential of bacteria living in the human gut is associated with levels of key chemicals in the brain, according to a new study published in Molecular Psychiatry. The research team from the University of Surrey ...
Medical Xpress / Your smartwatch may be lying to you about how many calories you burned
If you're depending on your smartwatch to tell you the truth about how many calories you burned during a workout—well, don't.
Medical Xpress / Decoding pet talk may help explain how pets affect our well-being

National Institutes of Health (NIH) researchers have discovered rare antibodies that could inform the development of an intervention for alpha-gal syndrome (AGS), an emerging tick bite-associated condition that can lead to ...
Medical Xpress / Smart walker boosts walking efficiency and dynamic balance in older adults
Researchers have evaluated a novel smart wheeled walker designed to enhance mobility and safety for aging populations. Published in JMIR Aging, the randomized crossover trial revealed that the smart wheeled walker significantly ...
Medical Xpress / New screening platform links molecule clusters to neurodevelopmental disorders
When drops of oil are added to water, the oil and water remain separate. Within cells, biological molecules cluster together in a similar way, separating themselves from the rest of the cell. And while they don't have a membrane, ...
Medical Xpress / How breakfast primes the response to the hormones that manage blood sugar
Vanderbilt researchers have discovered why the adage, "breakfast is the most important meal of the day," holds weight—especially for the 1 in 9 adults worldwide living with diabetes. Glucose (the simplest form of sugar) is ...
