How will the billion people who still use older 2G cellphones
use them to pay for goods, just like people with smartphones equipped with near-field communications
(NFC) wireless links? One answer is to place a tiny 2G base station at the point of sale so that those older non-NFC phones can also make a short-range transaction securely. More »
Someone has allegedly hacked into the cellphone of the beautiful Snooki, the elegant lady who is the beacon of good taste and faithful love in a show called Jersey Shore, the epitome of modern American values. Surprisingly enough, the hacker found naked pictures of her, which obviously were taken by coercion. More »
The four major wireless providers in the United States have partnered with the Federal Communications Commission in an effort to curb cell phone theft, The Wall Street Journal reported on Tuesday. The wireless companies will build a central database of stolen cell phones, which will track phones that are reported as lost or stolen and deny them voice and data service. The goal of the database is to reduce crime by making it very difficult to use a stolen device. Verizon Wireless and Sprint currently block phones that are reported stolen from being reactivated. AT&T and T-Mobile do not, although all four carriers have now agreed to be part of the new database. Members of Congress are also expected to propose legislation to make it a crime to alter a cell phone’s unique identification number, according to the report. Similar stolen-phone databases are already in place in the U.K., Germany, France and Australia. While crime hasn’t completely stopped, the number of incidents has apparently declined. Carriers will roll out individual databases within six months that will be centralized over a 12-month period, with smaller regional wireless providers expected to join the database over the next two years.
Much like carbon nanotubes

, terahertz technologies have been promising
miracles for nearly as long as humans have been able to distinguish water from fire. We exaggerate, but barely
. A crafty team assembled at the University of Pittsburgh seems to have no qualms with moving forward, however, recently announcing a new physical basis for terahertz bandwidth. Those involved managed to have success in generating a frequency comb -- "dividing a single color of light into a series of evenly spaced spectral lines for a variety of uses -- that spans a more than 100 terahertz bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal." For those who managed to make it through the technobabble, we're told that the ability to modulate light with such a bandwidth could "increase the amount of information carried by more than 1,000 times when compared to the volume carried with today's technologies." Smartphones, computers and even airline check-in kiosks that operate 1,000 faster than they do today? Sure, we'll take that. But, how about give us a ring when Wally World deems it ripe for commercialization? We'll be waiting -- pinky promise.
