Submission + - Lab-on-a-chip counts and sorts sperm (gizmag.com)

Submitted by cylonlover
cylonlover writes: While just about everyone is familiar with home pregnancy testing kits, what many of us may not realize is that a (sort of) equivalent product exists for men — home sperm count kits. These kits, however, will simply tell users if their sperm count is above or below a standard value. While a yes or no answer like that might suffice for the pregnancy kits, a little more information would definitely help a man who suspects he might be infertile. Loes Segerink, a PhD student from The Netherlands' University of Twente, hopes to change that with this prototype lab-on-a-chip device. Segerink's chip counts exactly how many sperm are present in a sample of ejaculate, and can even differentiate between the good swimmers and the duds.

Program Uses GPS To Track Sex Offenders 338

Posted by samzenpus from the where-do-you-think-you're-going dept.
43 sex offenders in Pennsylvania's Allegheny County are wearing GPS monitoring devices as part of a pilot program designed to keep track of their movements. If the offender moves into an "exclusion zone," police are called. “Exclusion zones for example [are] schools, daycares, playgrounds, facilities where children congregate for those sex offenders,” John Hudson, a security consultant, said. “We’ve identified in their red zones. If an offender with a device goes into one of the red zones, an exclusion zone, we’ll be notified immediately.”
