Nature vs. Nurture: Genetically Identical Twins May Differ In Traits Due To Epigenetic Changes From

Our tolerance for alcohol, musical talent (or lack thereof), or our personality traits can come from our genes or our upbringing. These two distinct views — nature or nurture — offer opposing explanations on how social behaviors develop and stay with us and our future generations. However, it’s not only our life experiences that influence our genes directly, it's also what our ancestors did centuries before we were conceived. In Ted-ED's video, "How the choices you make can affect your genes,” host Carlos Guerrero-Bosagna suggests epigenetics can explain why people with the same DNA (i.e., genetically identical twins) can turn out so differently, even in relation to traits that have a signi

Yoga Boosts Brain Function

Research has revealed that just one 20 minute session of Hatha yoga considerably improved speed and accuracy on tests of inhibitory control and working memory, 2 measures of brain function involved in the ability to maintain focus and take in, retain and also make use of new information. Individuals that took part in the study performed considerably better right after the yoga practice as opposed to after moderate to vigorous aerobic exercise for the identical time period. The yoga session entailed a 20 minute progression of standing, seated and supine yoga postures which included isometric contraction and relaxation of various muscle groups as well as controlled breathing. The session ended

Can Stress Make It Harder To Get Pregnant?

Couples struggling to conceive hear it all the time: Stressing about getting pregnant will just make it harder. Except being told that typically just causes even more stress, throwing those who are already under serious pressure into a bigger spiral of anxiety. But does being frazzled really make it harder to make a baby? The relationship between stress and infertility is a complicated one. Some research has suggested that yes, stress can hinder conception, while other studies have found that reducing stress doesn’t magically help a couple conceive. Everyone agrees on one thing, though: Going through infertility is incredibly stressful. And staying sane and healthy throughout the process is

New tool allows researchers to reproduce conditions of embryonic development in lab

An interdisciplinary team of developmental biologists and engineers at the Francis Crick Institute and the University of Maine have developed a new microfluidic tool that allows them to reproduce – in the laboratory – the same environments that cells are exposed to during the earliest stages of embryonic brain and spinal cord development. The tool, designed and fabricated by the MicroInstruments and Systems Laboratory at the University of Maine, is based on a technology called microfluidics. It has many potential applications for embryonic development studies, as well as applications in diagnostics and theraputics development for embryonic and neuromusculature diseases. Using the same equipm

Triplet and Higher-Order Births in US Down 41%

The rate of triplet and higher-order births rose rapidly during the 1980s and 1990s, but that trend has ended. According to a new report from the National Center for Health Statistics, the rate of triplet and higher-order births plunged 41 percent from 1998 to 2014. More than 90 percent of these births are triplets. Almost all of the decline occurred among women 25 and older, particularly women 45 and older, a drop of 67 percent to 769.9 per 100,000 births from 2,326. Non-Hispanic white women had the largest drop, about 46 percent. But rates of triplet or higher-order births were still 57 percent higher in this group than among non-Hispanic blacks, and more than twice as high as the rate amo
