Berkeley found a birth control that was hormone-free, 100 percent natural, resulted in no side effects, didn’t harm either eggs nor sperm, could be used in the long-term or short-term, and — perhaps the best part of all — could be used either before or after conception, from ancient Chinese folk medicine… “Because these two plant compounds block fertilization at very, very low concentrations — about 10 times lower than levels of levonorgestrel in Plan B — they could be a new generation of emergency contraceptive we nicknamed ‘molecular condoms, ‘” team leader Polina Lishko.

EzInKy writes: The BBC and others are reporting the results of a study that women’s brains do in fact change during pregnancy. BBC reports: “Pregnancy reduces grey matter in specific parts of a woman’s brain, helping her bond with her baby and prepare for the demands of motherhood. Scans of 25 first-time mums showed these structural brain changes lasted for at least two years after giving birth. European researchers said the scale of brain changes during pregnancy were akin to those seen during adolescence. But they found no evidence of women’s memory deteriorating. This study, from researchers at the Universitat Autonoma de Barcelona and Leiden University and published in Nature Neuroscience, looked at the brain scans of women before they became pregnant, soon after they gave birth, and two years later, to see how the brain changed. And they compared these women’s brains with those of 19 first-time fathers, 17 men without children and 20 women who had never given birth. The researchers found ‘substantial’ reductions in the volume of grey matter in the brains of first-time mothers. The grey matter changes occurred in areas of the brain involved in social interactions used for attributing thoughts and feelings to other people — known as ‘theory-of-mind’ tasks. The researchers thought this would give new mothers an advantage in various ways – help them recognize the needs of their child, be more aware of potential social threats and become more attached to their baby.” Thanks Mom! As for first-time fathers, the researchers found no changes in their grey matter. Read more of this story at Slashdot.
