George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.
Methylation: Gene Expression at the Right Place and Right Time

Courtesy of Richard Roberts, New England BiolabsModel methylation reaction: Cytosine nucleotide (red) is flipped out of the DNA double helix by a methyltransferase (white), so it can be methylated. The end product after the methyl group has been transferred to the DNA is pictured in green. A tenuous link between DNA methylation and development has existed for several years. Now findings substantiate the connection. Researchers have found the first human diseases caused by defects in the DNA meth
Science Museums Exhibit Renewed Vigor

Erica P. JohnsonApreschool girl with black braids presses a finger to a disk that twists a brightly lit DNA model, transforming its ladder shape into a double helix. Her head bops from side to side in wonder as the towering DNA coils and straightens. When a bigger boy claims her place, the girl joins meandering moms and dads with their charges as they twist knobs, open flaps, and simply stare at flashing helixes and orange information boards: all a part of the museum exhibit called "Genome: The

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.

Bioterrorism Research: New Money, New Anxieties
John Dudley Miller | Apr 6, 2003 | 8 min read
Ned Shaw US scientists have reason to feel both heady and scared. The federal government recently released unprecedented billions of dollars to fund bioterrorism research. Yet, the merits of this sudden shift in focus are being debated, and some worry that the money will be squandered or wasted. "I have been really very upset by the focus on bioterrorism," says Stanley Falkow, professor of microbiology and immunology and of medicine at Stanford University. "Everybody's talking about it, but th

Variations on a Gene

Photodisc Although President Bill Clinton surely had something in mind during his 2000 State of the Union address when he asked the nation to "celebrate our diversity," insights into human diversity at the molecular level are promising to speed drug discovery and revolutionize medicine to mark- edly improve human health. Individuals differ at one in 1,000 base pairs, which adds up to a whopping number of human genetic variations when applied to the roughly three billion base pairs of the human g
