...intelligence officers have joined the Pakistani probe, hoping it will provide clues to unmask and stamp out clandestine nuclear-procurement networks. The one Khan pioneered for Pakistan is considered a model for would-be Bomb builders. "I've always thought that A.Q. Khan's Rolodex is the most important thing of all in giving people advice on how to put all the pieces together," says Robert Oakley, former U.S. ambassador to Pakistan. Washington is worried that someone might barter away Pakistan's nuclear secrets to terrorists...
Magnetic resonance imaging (MRI) is a powerful scanning technology used to probe brain function and mental illness, including depression. It may also have a role in treating that disease. "We were using MRI to investigate the effectiveness of certain medications in bipolar patients," says Michael Rohan of McLean Hospital in Belmont, Mass., "and noticed that many came out of the MRI feeling much better than when they went in." A controlled study found that 23 of 30 bipolar subjects who had scans showed mood improvement. If larger studies confirm the effect, a tabletop version of the scanner could someday...
Attorney General John Ashcroft recused himself from the probe last week, and federal prosecutor Patrick Fitzgerald of Chicago was appointed to head it up. It's still likely that no charges will be filed when the investigation winds down. Whatever the outcome, it will test the adage that, in politics, the cover-up is more damaging than the crime...
...turns out that Tanzi might have had some far less noble impulses too. On Dec. 27, Tanzi was arrested, and he is confined in a Milan jail while Italian prosecutors, joined by the U.S. Securities and Exchange Commission, probe his role in an alleged $8.8 billion fraud that could implicate Parmalat in Europe's biggest corporate scandal ever, easily on a par with those of Enron and WorldCom in the U.S. Parmalat has filed for bankruptcy, and corporate-turnaround expert Enrico Bondi is trying to salvage what he can of the firm, which has 36,000 employees in 30 countries...
...getting, though, was a headache. The microscope, which detects the con-tours of molecules by dragging a flexible sliver of coated silicon over them, was malfunctioning. After puzzling through his problem for months, Thundat realized one rainy day during a rare midday foray outdoors that the microscope's probe was warping as it sponged up moisture from the air. Intrigued, he ran a simple experiment and discovered that the probe was a marvelously precise hygrometer. If it could measure moisture, he wondered, why not all sorts of other stuff? Thundat, 46, has since built tiny sensors to detect trace amounts...
