Writing in the February 27 online issue of Science Signaling, researchers at University of California San Diego School of Medicine and Moores Cancer Center describe how a signaling protein that normally suppresses tumors can be manipulated (or re-programmed) by growth factors, turning it into a driver of malignant growth and metastasis.
When women take the common diabetes medication metformin during pregnancy, it may put their children at increased risk of having obesity or overweight.
The average rate at which Americans tip for services has been increasing steadily for decades, but the practice has been branded over the years as classist, anti-egalitarian, and downright undemocratic, leading some restaurateurs to abandon it. A new paper, drawing insight from nonlinear dynamics and published in the journal Chaos, hopes to shed light on the economically irrational world of tipping, showing that at a certain point, banning the practice might be fair and profitable.
Athletes who suffer life-threatening heat stroke should be cooled on site before they are taken to the hospital, according to an expert panel's report published in the journal Prehospital Emergency Care. The principle of "cool first, transport second" differs from the usual practice of calling 911 and getting to the hospital as soon as possible.
Racial discrimination can have serious health consequences. A new study led by the University of California, Irvine has found that more self-reported incidents among black and Latino adults corresponded to higher blood pressure levels, putting these populations at greater risk for cardiovascular disease.

Emerging adulthood (between ages 18-25) is a period of critical vulnerability for problematic alcohol use. A substantial amount of research has examined alcohol risks in college-student populations, while much less research has focused on emerging adults who are not attending college. This study investigated the effectiveness of a brief personalized feedback intervention (PFI) tailored for nonstudent at-risk drinkers, the influence of gender on intervention outcomes, and the acceptability of the intervention to participants.
