...techniques.” “When you confine light to nanostructure dimensions and create artificial optical environments for the photons, interesting things happen to the photons,” Hu said. Hu mostly works with semiconductors, solid materials with electrical conductivity widely used in electronic devices like cell phones and computers. “By playing around at the nanoscale we have the potential to create new kinds of even more efficient optical sources,” Hu said. “Someday we may have integrated optical circuits.” Venky said...
...outside world. By checking their mail and parceling out telephone access - at scheduled times on easily and legally tapped landlines - communication for inmates was difficult and often expensive (their families had to pay for the hefty collect calls, usually the only kind allowed in jail). Today, however, as cell phones proliferate (with an estimated 3.5 billion and counting), they are reaching into every corner of the planet - including jail cells. Authorities in India recently confiscated more than 600 cell phones in a prison in the state of Gujarat. Not even high-security areas like Texas' death row are exempt...
...Cell-phone access can mean chaos. Brazilian officials say cell phones are used to organize and plan widespread riots that are endemic to their crowded prisons; Canadian prosecutors said a notorious drug kingpin continued business behind bars using his cell phone; and a man awaiting trial on a homicide charge in Maryland has been accused of arranging via cell phone the murder of a key witness in the case. The examples go on and on, some bordering on the absurd. The mother of a prisoner in Texas even called authorities to complain about her son's bad cell-phone reception...
Most prison cell-phone incidents, however, raise serious security concerns. Texas death-row inmate Richard Tabler allegedly used a smuggled cell phone in recent weeks to make threatening calls to Texas state senator John Whitmire, chairman of a key criminal jurisprudence committee. The calls were among 2,800 made in just one month from cell phones used by Tabler and nine of his fellow death-row inmates. After Whitmire alerted state prison authorities to the calls, the high-security East Texas prison was locked down and searched. Authorities found Tabler's phone hidden in the ceiling above a shower. They...
Even before Tabler's notorious calls, Texas prison authorities were investigating 19 cases of death-row cell-phone use and 700 cases throughout the entire state system. Tabler's mother and sister have been arrested on felony charges for buying cell-phone minutes and equipment for him. But it is not just family members who help smuggle the phones. Prison authorities say guards have been paid $2,000 - more than a month's wages - to bring in contraband cell phones. Small cell phones and postage-stamp-size SIMM cards are easy to smuggle into prisons in body cavities or simply...
