If you're the type who looks away when you get stuck with a needle, you may long for the day when "Star Trek"-style medical devices will painlessly flood our veins with every kind of drug imaginable.

For some women undergoing in vitro fertilization, daily intramuscular injections of progesterone in oil (PiO) can be painful and stressful. Infertility is already immensely taxing for some -- researchers have shown it can generate levels of anxiety and depression on a par with those from cancer, heart disease, and HIV.

Progesterone helps carry the pregnancy to term, but sometimes must be injected up to 70 times. PiOna is a concept auto-injector from Cambridge Consultants that not only hides the icky thing from sight, but provides feedback about when the 1.5-inch needle is ready to use and guides the user through the process. … Read more

The cancer ward at Seattle Children's Hospital will be overrun with cats tomorrow. Lots and lots of cats.

Normally, this would be extremely problematic in a sterile medical environment, but not in this case. Young cancer patients with immunities too low to participate in pet therapy will get to physically connect with the felines via an interactive online playroom. Rabbits, puppies, and goats too.

They'll do so via a live interface set up by Seattle Children's and Boise, Idaho-based Reach-in, which created the interactive technology that lets remote viewers control fluffy robotic cat toys in real time. It's not the same as holding a furry friend, but it might be the next best thing for these kids, some of whom must remain in total isolation while they battle cancer. … Read more

Want more Twitter followers? Have you considered advertising by tattoo?

TechCrunch writer Drew Olanoff is selling some real estate on his body to the biggest giver. Whoever wins will get his or her Twitter handled permanently etched on the 33-year-old.

Olanoff is, until November 14, raising money to help research into children's cancers. He did it before in 2009, when the high bid and donation was $2,112 by Melanie Mitchell, whose handle was inked on Olanoff's arm.

In an astonishing twist, Olanoff himself was diagnosed with cancer, Hodgkin's lymphoma, after that campaign. … Read more

Several months ago, my colleague Tim Hornyak wrote about the BeBionic 3 myoelectric prosthetic hand, a landmark prosthesis that enables a spectacular range of Terminator-like precise gripping and hand maneuverability.

A video making the rounds this week stars 53-year-old Nigel Ackland -- a wearer of the device -- who shows us that we've come extraordinarily far in prosthetic research, perhaps shockingly so if you don't keep up with the subject. … Read more

Devices that monitor inner ear activity could eventually be powered by the ear itself, according to research detailed in the current issue of the journal Nature Biotechnology by scientists from MIT, Massachusetts Eye and Ear Infirmary (MEEI), and the Harvard-MIT Division of Health Sciences and Technology (HST).

They say that for decades we have known the inner ear houses its own natural battery, but this is the first demonstration of its ability to power something external without compromising hearing.… Read more

Pacemaker users currently have to undergo surgery every 5 to 10 years to replace their device's battery. A new advance, however, could one day make pacemaker batteries obsolete.

A study presented at the American Heart Association's Scientific Sessions 2012 shared the results of an experiment using piezoelectricity to power a pacemaker. Essentially, this refers to the concept of turning motion into electricity. That means the beating of the heart could generate the power needed for a pacemaker to operate.… Read more

This Sunday, amputee Zak Vawter will stand at the foot of Chicago's Willis Tower and focus his thoughts on climbing. If all goes according to plan, his bionic leg will listen to those thoughts and he'll ascend 103 flights without a hitch.

Vawter, who lost his right leg in a motorcycle accident in 2009, will be wearing a cutting-edge, thought-controlled prosthetic that's about to make a very public debut. He'll head up the 1,451-foot skyscraper (also known as Sears Tower) as part of SkyRise Chicago, an indoor stair-climbing fund-raising event for the Rehabilitation Institute of … Read more

British scientists have come up with a super-sensitive prototype sensor that lets doctors detect early stage diseases with the naked eye, an innovation that could prove valuable in countries that lack the resources for expensive diagnostic equipment.

The sensor, created at Imperial College London, relies on nanotechnology to analyze serum derived from blood samples.

A positive reaction to p24, a protein that indicates early HIV infection, or PSA, a protein that at certain levels can indicate prostate cancer, generates irregular clumps of nanoparticles that emit a blue color in a solution kept in a disposable container.

A negative reaction, however, … Read more

True story. A few years ago, I got a concussion at a baseball game -- and not because a ball hit me in the head. When my friend and I simultaneously turned and leaned in to talk, her head hit mine with such force I thought I had broken my nose. My doctor, however, said all signs pointed toward a concussion. Did I mention it was a Giants game? Go, Giants!

World Series aside, had I been wearing a new impact-sensing skullcap from Reebok and startup MC10, I might have immediately known whether I needed medical treatment or rest before resuming play, which in my case involved sitting on a bench trying to explain baseball to CNET's Swedish summer interns.

The sensor-laden mesh cap provides colored LED readouts that vary according to the level of impact, thus providing instant information on the gravity of the blow. It should be commercially available to consumers early next year, "essentially serving as an extra set of eyes on the ice -- or any other playing field," MC10 says. … Read more
