CAN YOUR GENES MAKE YOU KILL?

The killer read his Bible. He drank. Heavily. It was a fall night in 2006, when Bradley Waldroup walked out of his rural trailer in southeastern Tennessee, carrying his .22 caliber hunting rifle. His estranged wife and her friend, Leslie Bradshaw, had just pulled up to drop off the Waldroups’ four children. Waldroup began arguing with his wife and Bradshaw, who was unloading the car. Drawing his gun, Waldroup shot Bradshaw eight times, killing her. He used a knife to cut her head open.

BRITISH SCIENTISTS WANT PERMISSION TO GENETICALLY EDIT VIABLE HUMAN EMBRYOS

While scientists around the world continue to debate the use of the CRISPR/Cas9 system, the tool capable of precisely editing DNA on the genomic level, British scientists working at the Francis Crick Institute in London announced today that they have applied for permission from the United Kingdom’s fertility regulator (the UK Human Fertilization & Embryology Authority) to use this technique on viable human embryos. If granted, this would allow them to directly study humans’ earliest stage of development and would mark the first approval by a national regulatory body to employ the CRISPR/Cas9 system on viable human embryos.

ROSES HAVE HIDDEN GENES THAT COULD MAKE THEM SMELL EVEN SWEETER

Roses are an ornamental plant, bred over hundreds of generations to have their distinctive shape and color. But what they gained in visual appeal they lost in their olfactory potency—that is, roses used to smell even sweeter than they do now. By manipulating some of the genes that control the rose’s fragrance, a team of French researchers has discovered new enzymes that could make roses smell more potent, according to a study published today in Science.
