Older children and teenagers may have a higher risk of obesity if they consistently don’t get enough sleep, according to recent Michigan Medicine research. The study, published in the Journal of Pediatrics, found the highest levels of obesity in adolescents who weren’t sleeping enough night after night, even more so than […]

Researchers can now explain how a cell that is being attacked by bacteria or viruses specifically manages to ‘sound the alarm’ among its neighbouring cells so they can react with a quick response. “We’ve succeeded in finding and describing a messenger which both quickly and effectively can inform the surrounding […]

Research by Professor Sonia Rocha and her team at the Institute of Integrative Biology reveals new insights into how cells respond to oxygen deprivation. Published in the prestigious journal Science, the researchers found that chromatin, the complex of DNA and proteins where all genes reside, quickly changes in response to low oxygen. Oxygen is essential for […]

One of the most common cancer-promoting genes, known as Myc, is also one of the most difficult to target with drugs. Scientists have long tried to develop drugs that block the Myc protein, but so far their efforts have not been successful. Now, using an alternative strategy, MIT researchers have […]

By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown that they can improve cognitive and memory impairments similar to those seen in Alzheimer’s patients. This noninvasive treatment, which works by inducing brain waves known as gamma oscillations, also greatly reduced the number of amyloid […]

Even as overall cancer incidence and mortality decrease in the United States, the number of people diagnosed with liver cancer is on the rise. Current therapies for liver cancer are largely ineffective, resulting in poor outcomes, but new preclinical data from University of California San Diego School of Medicine offers […]

While the human T- cell leukemia virus type 1 (HTLV-1) is known to cause a rare cancer of the immune system’s T-cells called adult T-cell leukemia or ATL in about five percent of those infected, researchers from the San Diego Supercomputer Center (SDSC) and Moores Cancer Center at UC San […]
