...companies offering to store our baby's cord blood as "insurance," as they they put it, against the day our child gets desperately ill. The idea is that by saving a baby's cord blood, you will have a source of stem cells that uniquely match his or her DNA. The Cord Blood Registry, which claims to be the oldest and largest of these blood banks, says it has frozen more than 300,000 samples at $1,975 a pop--plus a $125 storage fee every year thereafter. A video on its website urges parents to seize this "once...
...floor lab in Building No. 85 at Seoul National University, the center of operations for Woo Suk Hwang, the South Korean scientist who made headlines last week when he announced that his team, using Dolly-the-sheep techniques, had created 11 human stem-cell lines perfectly matched to the DNA of human patients--a giant leap beyond anything any other lab has achieved. The eggs hollowed out in Building No. 85 were fused with skin cells taken from nearly a dozen patients--ages 2 to 56, suffering from a variety of injuries and disorders--and grown with unprecedented efficiency into...
...After DNA from a human patient is inserted into a hollowed-out egg, the fused cell is stimulated electrically and chemically to get it to start dividing. At that point, other researchers have used animal-based growth factors and feeder cells to sustain the growing egg, but that creates problems if the cells are going to be used to treat humans. So Hwang has concocted a growth medium made of human-based nutrients, starting with human skin cells from one of the donor subjects...
...When Bush announced his Executive Order limiting federal funding to studies on existing stem-cell lines, he declared that private research had produced more than 60 genetically diverse lines that would be eligible. Researchers now say the number is more like 22, and even those are contaminated with mouse DNA, making them ill-suited for use on humans. Meanwhile, research is moving ahead without Washington's sanction--not only in places like Britain and Singapore but also in a number of states, led by California. The latest TIME poll found that 53% of respondents said they would like...
...Xbox 360. Microsoft, known more for its bullying business tactics than its technological innovation, is trying to act in a very un-Microsoft fashion. It's trying to be quick and nimble, radically innovative, and play well with others. It's trying to reinvent itself from the corporate DNA...
