Doctors have already replaced a patient's jaw with a 3D-printed titanium implant, so why not part of a skull? Earlier this week, 75 percent of an American patient's skull was surgically replaced with a custom-made implant produced by a 3D printer from Oxford Performance Materials.

The full name of the implant is the OsteoFab Patient Specific Cranial Device. The implant is made from PEKK biomedical polymer and printed using CAD files developed to fit each person. The world of skulls is not one-size-fits-all. Much like an expensive pair of bespoke shoes, these skull implants are unique to the individual.… Read more

What if you could "street view" the human body, navigating its interactive components all the way down to a metabolic level? An international group of scientists is working on that right now with a map of the human metabolism, which they call Recon 2.

Metabolism plays a key role in many diseases, and while scientists have already managed to reconstruct several models of it, each "represents only a subset of our knowledge" with "only partially overlapping content," the team writes in the journal Nature Biology.

"It's like having the coordinates of all the cars in town, but no street map," Bernhard Palsson, a professor of bioengineering at the University of California San Diego Jacobs School of Engineering and one of the authors of the paper, said in a statement. "Without this tool, we don't know why people are moving the way they are."… Read more

In journalism, there's a phrase you'll often hear that refers to the paragraph toward the beginning of a story that sums it all up in a nutshell. We call it the "nut graph," and as you're about to read, it's a term that's never been more appropriate than in the case of Joshua Shoemake's current project on Kickstarter.

Shoemake is looking to crowdfund $20,000 for the first production run of Snowballs, a specially designed pair of men's underwear loaded with ice packs that cool down the scrotum and testes in hopes of increasing sperm count and mobility (and ergo, fertility)… Read more

SEATTLE -- Technology giants such as Google and apparel makers such as Nike are pouring millions into wearable computing, betting that it's one of the next untapped frontiers in consumer electronics.

Runners slip sensors into their shoes to track how far they've gone. Insomniacs wear wristbands to monitor their sleep habits. Skiers don goggles with heads-up displays to see how fast they're moving.

But wearable computing remains a niche business. Even as the cost and size of the sensors the devices use has dropped, and the ability to transmit the data those sensors collect to smartphones has … Read more

When it comes to scientific research, size matters -- and yes, bigger is better.

So it may come as no surprise that scientists at Stanford, Columbia, and Microsoft have used Internet search data to uncover prescription drug side effects faster than the FDA's current gold standard, the Adverse Event Reporting System. After all, the data miners had the activity of some 6 million Internet users at their disposal, whereas the FDA relies on physicians to notice and report problems.

Reporting today in the Journal of the American Medical Informatics Association, the researchers write that by analyzing Google, Microsoft, and … Read more

Testing for strokes can be inaccurate and expensive. But a new device that looks like a pair of swimming goggles may offer a better, cheaper alternative, and save tens of thousands of lives every year.

The goggles, equipped with an infrared camera attached to a cord that goes to a laptop computer, measure eye movements, Dr. David Newman-Toker, an associate professor of neurology at the Johns Hopkins University School of Medicine, explained on "CBS This Morning."

"The eye movements (when) patients present with strokes in the back part of the brain -- and that's about one out of every four strokes -- the patients present with dizziness and vertigo and we can tell from their eye movements whether they've had a stroke or whether they have a benign inner-ear condition, quickly and easily," said Newman-Toker, who is leading the study of the new technique.

The goggles will work best as strokes occur, Newman-Toker said, and will likely find use in emergency rooms. … Read more

Canon has developed a video sensor that can capture images illuminated only by a glowing incense stick or the light of a crescent moon.

The sensor gathers light by using extremely large pixels -- 7.5 times the surface area of those in the 18MP EOS-1D X professional SLR, whose 35mm full-frame sensor is the same size. In conjunction with that approach, "the sensor's pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases," Canon said in its announcement. Check the link to watch Canon's sample video.

HANOVER, Germany--IBM showed off technology today designed to let people use their smartphones to take command of their real-world shopping.

Big Blue showed an app idea from IBM Research in Haifa, Israel, that uses image recognition to identify products on store shelves, then lets people sort those products by attributes such as price and nutrition information. A customer could select only gluten-free products, pick food that's from nearby, or filter electronic gadgets by operating system.

"The same experience people expect online is available in the store," said Amnon Rebak, a research staff member on the project, at … Read more

In an unprecedented case, doctors in Mississippi believe they have "functionally cured" a toddler of an HIV infection.

Recent tests of a 2-year-old born premature with the disease show no detectable levels of the virus, according to the National Institutes of Health. Doctors credit early administration of antiretroviral therapy for curing the child, who shows no signs of the virus after a year off the drugs.

"Despite the fact that research has given us the tools to prevent mother-to-child transmission of HIV, many infants are unfortunately still born infected," Dr. Anthony S. Fauci, director of National … Read more
