Treating a mouse model of multiple sclerosis with the pregnancy hormone estriol reversed the breakdown of myelin in the brain’s cortex, a key region affected in multiple sclerosis, according to a new UCLA Health study. BACKGROUNDIn multiple sclerosis, inflammation spurs... Continue Reading →
While conducting a study of Petermann Glacier in northwest Greenland, researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could... Continue Reading →
Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows. Led by researchers from... Continue Reading →
A preclinical study using stem cells to produce progenitor photoreceptor cells—light-detecting cells found in the eye—and then transplanting these into experimental models of damaged retinas has resulted in significant vision recovery. This finding, by scientists at Duke-NUS Medical School, the... Continue Reading →
In adolescents, sedentary time may increase heart size three times more than moderate-to-vigorous physical activity, a paper published in the Scandinavian Journal of Medicine & Science in Sports concludes. The study was conducted in collaboration between the University of Bristol in the... Continue Reading →
Having high blood pressure in your 30s is associated with worse brain health around age 75, especially for men, according to a new UC Davis study. The research, published this week in JAMA Network Open, compared magnetic resonance imaging (MRI) brain scans... Continue Reading →
Researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) have developed a small-molecule drug that prevents weight gain and adverse liver changes in mice fed a high-sugar, high-fat Western diet throughout life. “When... Continue Reading →
A growing pile of evidence indicates that the tens of trillions of microbes that normally live in our intestines — the so-called gut microbiome — have far-reaching effects on how our bodies function. Members of this microbial community produce vitamins,... Continue Reading →
This amazing feat was achieved with optical traps, which use a highly focused laser beam to hold and move tiny objects. Although optical traps have been used to move individual atoms before, this is the first time an atom has... Continue Reading →
