When a school therapist suggested that a family buy their autistic 3-year-old son Hudson an iPad, the Holmquists were willing to give it a try, and turned to ChipIn to raise money for a tablet for their child. Now the family is telling news media the device is a miracle.

Hudson, who was diagnosed with autism in 2010, went from several violent meltdowns a day (including one screaming session that lasted from morning until late evening) to, well, fewer violent meltdowns.

"The iPad has given us our family back," Laura Hudson told FoxNews.com. "It's unlocked a new part of our son that we hadn't seen before, and given us insight into the way he connects with his world."

Perhaps more surprising is that autism experts aren't surprised. Hudson is able to use the tablet not just for gaming and making puzzles but even for communicating ideas to a family that is really just now getting to know the kid behind the tantrums. … Read more

For the first time, a device that gives the sightless a second chance to see has been approved in Europe.

CBS News medical correspondent Dr. Jon LaPook reports that the FDA may do the same here soon.

Barbara Campbell lost her sight 20 years ago from retinal disease, but now her world is a lot brighter than it used to be. That's because 2 years ago, she was one of the first patients to get an artificial retina.

"My goal was to see colors and go the Grand Canyon," Campbell said.

With the new retinal-replacement device, Barbara … Read more

It's an age-old question: why am I sleeping poorly?

As we reported earlier today, a new study from the National Sleep Foundation says the active use of electronic devices such as TVs, smartphones, computers, and video games one hour before going to bed might be what's keeping us awake.

For its 2011 Sleep in America poll, the NSF queried a random sample of 1,508 adults between the ages of 13-64. Almost everyone surveyed, 95 percent, said they use some type of electronics at least a few nights a week within an hour before bed.

CBS "Early Show" contributor Taryn Winter Brill, like many, goes to bed with the TV on or has her laptop or BlackBerry close by. She decided to set up an unscientific sleep experiment to find out why she's sleep-deprived. What happened when Winter Brill pulled the plug on all of her technology? She shares the results with "Early Show" viewers and co-anchor Erica Hill.

Originally developed in the early 1990s to promote plant growth on board space shuttles, the light technology behind NASA's Astroculture 3 is now being repurposed to help soothe the painful side effects that can result from chemotherapy and radiation treatment in patients with bone marrow and stem cell transplants.

The treatment device, called WARP 75, uses High Emissivity Aluminiferous Luminescent Substrate, or HEALS, which lets LED chips function at their maximum irradiance--the equivalent light energy of 12 suns from each of the device's 288 grain-of-salt-sized LEDs--without emitting heat.

Researchers studied the effects of the technology to treat oral mucositis… Read more

Nobody likes a conversation interrupted by the mobile-device grab, that increasingly familiar maneuver by which someone betrays a total lack of interest in said conversation and searches for whatever else might be going on in the world instead.

But when your physician gets device-happy in the middle of your next doctor's visit, even in the ER, chances are it's for a good cause, such as looking up the latest on your condition in a reference guide.

Rosen and Barkin's best-selling 5-Minute Emergency Medicine Consult has, for years, been a six-pound, 1,300-page clinical reference tome designed to support urgent care providers. Now, Unbound Medicine is releasing the new-and-improved fourth edition for mobile devices (including iOS, Android, BlackBerry, etc.) in a "proven, rapid-access format."

At $99.95, the price tag is heftier than it is for the paper product (at the time of this posting the hardcover is $81.64 on Amazon), but it features not only the guide's 600-plus urgent care topics and updated protocols and treatment guideline, but also personalized "favorites" (perhaps not the best word) for symptoms and conditions a user might encounter more frequently.… Read more

Viruses are small. Very small. There are millions of types, and the 5,000 or so that have been studied in detail are typically between 10 and 300 nanometers (one-billionth of a meter) in diameter.

Because the wavelengths of visible light range from roughly 300 to 800 nanometers, viruses aren't exactly visible under normal lighting. Only optical fluoresce microscopes can see inside a virus, and then only indirectly, using dye, which cannot actually penetrate a virus.

So the "microsphere nanoscope" developed by scientists at the University of Manchester's School of Mechanical, Aerospace, and Civil Engineering in the U.K. and described in the journal Nature Communications is remarkable on two counts: It breaks the world record of direct imaging under normal lights by 20 times, viewing objects as small as 50 nm wide, and what's more, the tech behind it imposes no theoretical limit in the size of feature that can be seen.

This incredible jump in capacity could allow humans to see inside human cells and even live viruses for the first time, which in turn could give us many new insights into their structures and behaviors.… Read more

I don't run much because I'm counting on getting superhuman robotic legs in the future. But if I were a runner, Merrell's new Go Barefoot running app might be kinda appealing now that I understand it's only half-serious in suggesting I go running barefoot.

The new free app is the first barefoot running training and education app for the iPhone, according to the footwear maker, which happens to make a line of "minimalist shoes" called Barefoot. Hence the app name.

Minimalist shoes are flat, with the barest of protection from the elements and the terrain.

Go Barefoot "provides the proper training and education for a barefoot or barefoot-like running experience," a publicist explained, dispelling my confusion. So you can use it with or without shoes.

The app has four stages of expert training, including how to run barefoot by striking the ground closer to the ball of the foot instead of the heel. You can also track time and distance with the GPS function.

The app also comes with an iTunes mix of music that plays at 180 beats per minute to sync with a running cadence.

Go Barefoot is structured around a 40-day regimen of workouts and fitness tests to prepare for the challenge of a "1.5-mile barefoot run," which presumably means no shoes whatsoever.

Not even Barefoot shoes. … Read more

A Web site and app out of Germany applies the wiki approach to maps, enabling users around the world to use the OpenStreetMap platform to rate and comment on the wheelchair accessibility of a wide range of establishments, from bars and shops to underground metro stops.

Called Wheelmap, the free app for iOS devices is in English, German, and Japanese, and while still in beta (version 1.1 adds Japanese), it already includes details on some 30,000 locations, with roughly 300 new user ratings every day.

Wheelmap is the brainchild of Raul Krauthausen, who wanted to create a service … Read more

You forgot to feed your gerbil. In the middle of the night, it escapes its cage and gnaws off your ear. Who you gonna call? Your local 3D print shop. It'll run off a perfect copy of your ear in no time flat.

This is the kind of futuristic scenario that Cornell University's Hod Lipson and colleagues have been painting while discussing "bioprinting" at a meeting of the American Association for the Advancement of Science in Washington, D.C.

Bioprinting refers to the practice of using 3D printing to make biological tissue such as skin, bone, and cartilage.

The technology has been around for two decades, but researchers recently began using it to create biological structures. The idea is to make custom-designed tissue and organs from a patient's own cells, perhaps eliminating the need for donated organs.

Companies like Organovo are already developing bioprinted blood vessels, which will be essential for artificially grown organs.

"The next big thing and next logical step is [the] development of robotic methods of functional human tissue and organ bioassembly," Vladimir Mironov of the Medical University of South Carolina wrote in a meeting abstract. Mironov has been trying to grow meat in his lab for a decade.

One study has shown how tissue engineering was used to repair a calf's femur. Printing organs such as livers could be next. … Read more
