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

A GRADIENT OF PORE SIZES:Courtesy of Michael J. Sailorimparts a rainbow of colors to a porous silicon chip, one of a variety of new biosensor technologies in development around the world. The different colors correspond to different sized pores, ranging from a few nanometers to hundreds of nanometers in diameter. These pores help the device discriminate and detect proteins and other molecules based on their size.One morning in March 1995, the deadly nerve gas sarin wafted through the Tokyo subwa

In due course, these transposable elements, or transposons, were found to be ubiquitous in nature, and 30 years later McClintock won the Nobel Prize. Today transposons have gone from molecular oddity to molec
Nanotech Dreams
Jeffrey Perkel | Mar 3, 2002 | 9 min read
Nanotechnology hit the big time in July 1995, when it debuted on the television show, The Outer Limits. In an episode entitled "The New Breed," a scientist develops nanorobots capable of repairing damaged cells and correcting physical defects. But, like any good morality play, the experiment goes horribly wrong, turning a panacea into a nightmare. Clearly, nanotechnology makes for good science fiction, but scientists have been working to make it an interesting reality, too. Nanotechnology refers
