Novel interventional radiology procedure zaps around complicated pancreatic tumors

Results of a study presented at the Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif., signal a light at the end of the tunnel for individuals with inoperable locally advanced pancreatic cancer (LAPC). A new procedure called irreversible electroporation or IRE uses microsecond electrical pulses to force open and destroy tumor cells around a vast and delicate network of blood vessels of the pancreas.

Cooler hands may improve results of work out: Study

Researcher Stacy Sims, a research scientist and exercise physiologist at Stanford University School of Medicine presented her findings Tuesday at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism scientific sessions in San Diego. “If you think about adipose [fat] tissue, it's a great insulator,” Sims said. For people who are obese, that means they often get too hot while exercising. “It would be like Lance Armstrong wearing a wet suit for the entire Tour de France,” she said. “We're trying to address those barriers.”

Promising results from initial trial of new ultrasonic breast cancer screening

Scientists have successfully completed an initial trial of a new, potentially more reliable, technique for screening breast cancer using ultrasound. The team at the National Physical Laboratory (NPL), the UK's National Measurement Institute, working with the University Hospitals Bristol NHS Foundation Trust, are now looking to develop the technique into a clinical device.

Ion channels assembled in different combinations distinguish temperatures

The winter sun feels welcome, but not so a summer sunburn. Research over the past 20 years has shown that proteins on the surface of nerve cells enable the body to sense several different temperatures. Now scientists have discovered how just a few of these proteins, called ion channels, distinguish perhaps dozens of discrete temperatures, from mildly warm to very hot.
