Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke.

A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has found a non-invasive and non-pharmaceutical method to influence glymphatic transport using focused ultrasound, opening the opportunity to use the method to further study brain diseases and brain function...

From low-carb to intermittent fasting, surgery to Ozempic — people turn to a seemingly never-ending array of diets, procedures and drugs to lose weight. While it has been long understood that limiting the amount of food eaten can promote healthy aging in a wide range of animals, including humans, a new study from University of Michigan has revealed that the feeling of hunger itself may be enough to slow aging.

Previous research has demonstrated that even the taste and smell of food can reverse the beneficial, life-extending effects of diet restriction, even without its consumption.

These intriguing findings drove first author Kristy Weaver, Ph.D., principal investigator Scott Pletcher, Ph.D...

A new genomic urine test can predict bladder cancer as many as 12 years before clinical signs and symptoms emerge, according to a study presented at the annual meeting of the American Urological Association, held from April 28 to May 1 in Chicago.

Yair Lotan, M.D., from the UT Southwestern Medical Center in Dallas, and colleagues examined the effectiveness of screening for preclinical urinary carcinoma (UC) with a modified UroAmp (Convergent Genomics) genomic profiling test using 10 genes. The analysis included a model evaluation case-control design with 96 controls and 70 UC cases, as well as a nested case-control design within the Golestan Cohort Study (50,045 participants followed for up to 12 years).

The researchers found that the UC screening model was trained to a sensitiv...

Your brain is responsible for controlling most of your body’s activities. Its information processing capabilities are what allow you to learn, and it is the central repository of your memories. But how is memory formed, and where is it located in the brain?

Although neuroscientists have identified different regions of the brain where memories are stored, such as the hippocampus in the middle of the brain, the neocortex in the top layer of the brain and the cerebellum at the base of the skull, they have yet to identify the specific molecular structures within those areas involved in memory and learning.

Research from our team of biophysicists, physical chemists and materials scientists suggests that memory might ...
