There’s a human liver sitting in a lab dish in Madison, Wis. Also a heart, a brain and every bone in the human body even though the contents of the dish are a few cells too small to be seen without a microscope. But these are stem cells, the most immature human cells ever discovered, taken from embryos before they had decided upon their career path in the body. (46) If scientists could only figure out how to give them just the right kick in just the right direction, each could become a liver, a heart, a brain or a bone. (47) When a team from the University of Wisconsin announced their discovery, doctors around the world looked forward to a new era of medicine one without organ-donor shortages or the tissues-rejection problems that bedevil transplant patients today.
Doctors also saw obstacles, though. One of them was a U. S. Congress skittish about research on stem cells taken from unwanted human embryos and aborted fetuses. Indeed, 70 lawmakers asked i

Singapore’s Mixed Reality Lab is working on new ways of interacting with computers, including wearable devices and virtual war room that will allow officials to work together online as if they were all in one place. Its director is a spiky-haired Australian, a postmodern match for the fictional British agent James Bond’s tool man, O. It is funded by the Defense Science & Technology Agency, which controls half the $ 5 billion defense budget, and sponsors hundreds of research projects every year. The agency came to worldwide attention last year when it took just one day to customize a thermal scanner in order to detect travelers with high fever, helping to stem the spread of SARS.
DSTA is now working on a range of projects that are attracting attention in both the commercial and military worlds. It devised an air-conditioning system that harnesses melting ice and cool seawater to conserve electricity at the new Changi Naval Base, and could have broad
