Scientists have sequenced the full genomes of 91 sperm from one man, the first complete sequencing of a human gamete cell. It demonstrates the vast genetic variation in one person, according to genetic researchers at Stanford.
In a new study fraught with some heady ethical questions, scientists have sequenced almost the complete genome of an unborn child, and done so without interrupting the fetus or the mother’s womb. The team used the mother’s blood and the father’s saliva to determine their child’s genetic sequence in the second trimester.
Two high school students armed with DNA barcoding tech uncovered quite a few food shenanigans in New York City markets. Examples include expensive "sheep's milk cheese" made from cow milk, "venison" dog treats made from beef, and "sturgeon caviar" that was actually Mississippi paddlefish.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
