How Does What We Eat Affect Our Healthspan and Longevity? It’s a Complex Dynamic System
Summary: Study sheds new light on how normal variations in dietary patterns affect human aging, longevity, and overall health. Source: Columbia University The answer to a relatively concise question – how does what we eat affect how we age — is unavoidably complex, according to a new study at […]
How Good Are We at Finding Optimal Solutions to Complex Problems? People May Not Be as Apt as Generally Assumed
Summary: Pure free exploration may not be the most efficient route to solving a complex problem or learning, a new study reports. Source: Champalimaud Centre for the Unknown Who hasn’t felt the temptation to fling a lengthy manual into the trash, or just drive on instead of asking for […]
Complex Human Childbirth and Cognitive Abilities a Result of Walking Upright
Summary: Bipedalism dramatically reshaped the hominin pelvis into a real birth canal. Researchers report Australopithecus had complex birth patterns compared to Great Apes and were likely to have practiced co-operative breeding. Source: University of Zurich During human birth, the fetus typically navigates a tight, convoluted birth canal by flexing […]
