Regular exercise reshapes the immune system at a cellular level, study suggests (opens the original)
Read excerpt
It's well-known that regular exercise comes with health benefits, but exactly how those benefits manifest at the cellular level isn't clear. Now, researchers have identified a series of changes in metabolism and the immune system that differentiate regular exercisers from people with sedentary lifestyles. The findings, published Sept. 18 in the journal Science Advances, point to potential pathways for managing chronic diseases, such as diabetes, heart disease and cancer, the scientists say. The
1 million people's genes reveal the heritability of the Big Five personality traits — and it's complicated (opens the original)
Read excerpt
A family photo album can reflect how physical traits, such as blue eyes or lanky limbs, have been passed down — but a new analysis suggests that the way personality emerges across generations is far more complicated. The meta-analysis, published Sept. 2 in the journal Nature, is the largest of its kind ever attempted. The work identified over 1,200 genes linked to five personality traits: extraversion, agreeableness, conscientiousness, openness to experience and neuroticism. However, the scienti
Pigs wearing heated diving suits and diapers reveal a better way to beat 'the bends' (opens the original)
Read excerpt
Deep-sea divers take careful measures to avoid "the bends," a painful condition where gas bubbles form in divers' blood and tissues when they ascend from the depths too quickly. Now, a new study using unlikely test subjects — pigs in diving suits — has shown that switching up the gas they breathe underwater may help divers avoid this dreaded decompression sickness. One day, the lessons from the research may help humans dive deeper for longer and get back to the surface more quickly, the study au
Could we prevent dementia? A new trial may point the way. (opens the original)
Read excerpt
LONDON — In the packed halls of the recent Alzheimer's Association International Conference in mid-July, over 10,000 experts in brain research discussed strategies to beat dementia. But in one room, attendees gathered to watch a video from a nonscientist named Isabel Beltre, whose life was transformed by a recent trial. Beltre was one of 1,200 participants ages 60 to 77 who took part in the Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS), the fir
Alzheimer's blood tests are transforming how patients get diagnosed — here's what to know (opens the original)
Read excerpt
LONDON — New blood tests for Alzheimer's disease aim to catch the condition in its earliest stages. Scientists hope that, someday, by spotting very early signs of dementia and enabling earlier treatments, these tests could significantly improve patients' prognoses. But how well do current blood tests work for that purpose? At the Alzheimer's Association International Conference in London on July 12-15, Live Science spoke with researchers and clinicians who study and use blood tests for Alzheim
