Secret Hours

In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.

Oncologists often have to wait months before they can determine whether a treatment is working. Now, using a non-invasive method, researchers at UCLA's Jonsson Comprehensive Cancer Center have shown that they can determine after a single cycle of chemotherapy whether the toxic drugs are killing the cancer or not.

Researchers have developed a technology that detects damage to critical suspension components in military vehicles simply by driving over a speed bumplike "diagnostic cleat" containing sensors.

"Our aim is to save time and maintenance costs, but more importantly to reduce downtime by catching damage before it leads to failure in the field," said Douglas Adams, an associate professor of mechanical engineering and director of Purdue University's Center for Systems Integrity.

If the experience of the American troops already training police officers in Ghazni Province is any indication, better policing may be impossible for Afghanistan unless government officials at all levels stop cannibalizing their civil administration and police force for a quick profit.
