Egyptian President Mohamed Mursi sought to contain growing sectarian turmoil as the death toll from days of Muslim-Christian clashes climbed to eight and the opposition seized on it as another example of his failures.
The Faroe Islands, a tiny, windswept land halfway between Scotland and Iceland, is so barren its 50,000 inhabitants import almost everything except fish and sheep. Now it wants to leap to the frontier of genetic medicine.
It takes millions of years for a new species to evolve. George Church says he can do it in days. The towering, bearded 56-year-old Harvard Medical School professor is a pioneer in the fast-growing field of synthetic biology, in which scientists manipulate DNA to create organisms that don't exist in nature. Soon, researchers may be able to develop waterproof cotton or bananas that stay ripe for months, according to scientists in Church's lab.
On the fourth floor of a red brick medical building in Boston’s South End is an office where few want to go -- where people get a frequently unwelcome glimpse of their future through a careful reading of their DNA.
Biologists have replaced parts of the E. coli bacterium DNA using a new process that hits many targets at once, a feat that may enable scientists to significantly alter or re-engineer genetic material.
