Going to the doctor to see if you have strep throat might be a hassle, but it's next to impossible for people who live in remote regions with limited access to healthcare. Researchers from Florida Atlantic University have created a sensitive film that can detect viruses and bacteria, such as HIV and Staph, at home. The film could be used in remote regions, helping medical professionals diagnose diseases and decide on the best treatment from afar. The researchers published their findings in a recent issue of Scientific Reports.

For us average folks, smartphones have already merged several gadgets into one: our phones, our media players, even our computers. Now they may be taking over a more specialized field: the doctor's bag.

In the mobile age, we're largely unfettered by wires, thanks in no small part to Wi-Fi, cellular networking, and the rise of laptops, smartphones, and tablets.

Want to turn your smartphone into a cosmic ray detector? Well there's an app for that. Cosmic Rays Found in Smartphones, or CRAYFIS, uses smartphones' and tablets' standard camera equipment to detect some of the super-rare particles that shower down on the Earth when a high-energy cosmic ray hits the atmosphere. CRAYFIS collects that data, then sends them onto physicists at the University of California's Irvine and Davis campuses for analysis.

Modern smartphones usually offer some kind of security option to let you into the phone. The iPhone has the a four-digit PIN-like passcode, Android phones have a swiping pattern, Windows Phone has a numeric or text-based password. Those work OK, but they're pretty hackable, and could well be improved by new technologies. Insidious and scary technologies. Here's the rundown.

We've all grown quite used to the idea of botnets stowing away on PCs out there on the Internet, spamming us from hacked inboxes in unknown places. Now, botnets are going mobile. Microsoft researcher Terry Zink says he's discovered evidence that an illegal botnet has hijacked smartphones running Google's Android operating system and used them to send spam from users' Yahoo email accounts.
