By boosting innate immunity can eradicate aggressive prostate cancer in mice

Drug activates neutrophils instead of T cells, leading to cancer clearance

University of Chicago Medical Center

Cabozantinib, an FDA-approved drug for patients with certain types of thyroid or kidney cancer, was able to eradicate invasive prostate cancers in mice by causing tumor cells to secrete factors that entice neutrophils -- the first-responders of the immune system -- to infiltrate the tumor. This novel approach, utilizing the innate immune system, produced near-complete clearance of invasive prostate cancers within 48 to 72 hours.

How healthy is genetically modified soybean oil?

University of California-Riverside Soybean oil accounts for more than 90 percent of all the seed oil production in the United States. Genetically modified soybean oil, made from seeds of GM soybean plants, was recently introduced into the food supply on the premise that it is healthier than conventional soybean oil. But is that premise true? Just barely, say scientists. Researchers at the University of California, Riverside have tested a genetically-modified (GM) soybean oil used in restaurants and found that while it induces less obesity and insulin resistance than conventional soybean oil, its effects on diabetes and fatty liver are similar to those of conventional soybean oil.

Babies are born to dance, new research shows

University of York The findings, based on the study of infants aged between five months and two years old, suggest that babies may be born with a predisposition to move rhythmically in response to music. The research was conducted by Dr Marcel Zentner, from the University of York's Department of Psychology, and Dr Tuomas Eerola, from the Finnish Centre of Excellence in Interdisciplinary Music Research at the University of Jyvaskyla.

Using mushrooms as a prebiotic may help improve glucose regulation

August 16, 2018 Penn State Eating white button mushrooms can create subtle shifts in the microbial community in the gut, which could improve the regulation of glucose in the liver, according to a team of researchers. They also suggest that better understanding this connection between mushrooms and gut microbes in mice could one day pave the way for new diabetes treatments and prevention strategies for people.
