‘This is pinpointing a region that was a needle in a haystack,’ says Vincent Harley, a molecular geneticist at the Hudson Institute of Medical Research in Clayton, Australia, who was not involved in the new study. ‘[The switch] seems alone to be able to do the job’ of making a man.
If left to their own devices, all human embryos would develop into girls. But a gene on the Y chromosome, named SRY, brings about a change in early development, causing testes, a penis, and other male traits to form. This gene indirectly turns on another gene called Sox9, which kick-starts the construction of the testes

Sex-change mice research could help humans, say scientists

Scientists have turned male mice into females by snipping out strands of their DNA in work that could shed light on sexual development disorders which arise in humans.

The male mice grew ovaries and female genitalia instead of the more conventional male anatomy after researchers removed small chunks of DNA from the animals’ genetic code.

The findings could help explain why people with XY chromosomes who are missing similar strands of DNA can go on to develop female sex organs, the scientists say. Males are typically born with X and Y chromosomes, while females have two Xs.

How recovered memories and a single drop of blood were the key that led to a conviction

When Diane Marcell unlocked the door to her Albuquerque, New Mexico home just before noon on Sept. 11, 2008, she was expecting to meet her daughter Brittani Marcell there for lunch.

Continue.

Brittani, the fifth-born of Diane’s seven children, was lying on the ground just inside the house, covered in blood, and a man was standing over her holding a shovel.

Continue.

Brittani’s purse, shoes and the CDs and DVDs that she borrowed from the library that day were scattered on the ground, dropped as she was hit in the head by the man wielding the shovel.

Amanda Peet, playwright: How the actress became the author of the Geffen’s upcoming premiere

Amanda Peet says her house often resembles a lunatic asylum. That’s largely in reference to the outsized creative endeavors of her three young children, but it’s also a description of a household devoted to writing — a solitary and crazy-making pursuit.

Peet may be best known as an actress, having appeared in films such as “The Whole Nine Yards” and “Syriana” and in TV shows, including the Duplass brothers’ family dramedy, “Togetherness.” But she’s also a serious writer, with her second play, “Our Very Own Carlin McCullough,” set to begin previews Tuesday for its world premiere at the Geffen Playhouse.
