Cartilage grown from patients' noses used to repair their knees

Depending on the part of the body and the nature of the injury, cartilage either doesn’t grow back at all, or does so very slowly. That’s why joint injuries often take a long time to heal, to the point that scientists are looking into using things like hydrogels and 3D printers to help speed the process. Now, however, researchers from Switzerland’s University of Basel are reporting that cartilage cells harvested from a patient’s own nose can be used to grow replacement cartilage for their knee.

Spongy polymer developed to fill holes in bones

Whether they're the result of injuries, surgery or birth defects such as cleft palate, missing sections of bone in the skull or jaw can certainly affect someone's appearance. Although there are some methods of filling in such gaps, they have limitations that limit their application. A newly-developed foam-like material, however, may be able to succeed where other approaches have failed. Read More

Students developing an injectable foam to treat battlefield wounds

When a soldier is wounded on an extremity such as an arm or leg, applying a bandage and/or tourniquet to stop the bleeding is typically a fairly straight-ahead process. However, in cases where an injury is received right at the junction between an extremity and the torso – places such as the neck, shoulder or groin – things get a lot trickier. Gauze pads treated with clotting agents are often packed into the wound, although they're not always sufficient for staunching the flow. A group of students from Johns Hopkins University are working on a better alternative, in the form of a hardening foam that's injected into the wound. Read More

DARPA wants to develop electronic memory-restoring implants

Earlier this year, we heard about how DARPA (the Defense Advanced Research Projects Agency) was setting up its new Biological Technologies Office. The goal of that division is to "merge biology, engineering, and computer science to harness the power of natural systems for national security." This week, the agency released details of one of the office's key projects, called Restoring Active Memory. It's aimed at using implantable "neuroprosthetics" to help army veterans and other people recover from memory deficits caused by brain injury or disease. Read More

"Bruise trousers" are designed to let disabled athletes know when they're hurt

Along with the obvious mobility issues faced by athletes who are unable to walk, they also face another challenge – if they're unable to feel their legs, that means they can't always tell when they've been hurt. Severe bruises or broken bones can simply go unnoticed, until they develop into even more of a problem. That's why a group of students at Imperial College London have invented a set of "bruise trousers" that show such athletes when and where they've received a serious impact below the waist. Read More

Reversible glue could save soldiers' sight

When soldiers or other people sustain eye injuries, retinal detachment and vision loss can result if the eye's vitreous gel isn't kept from leaking out. Given that Band-Aids can't be placed directly on the eyeball, however, a team of scientists from the University of Southern California has created an alternative – reversible eye glue. Read More

Broken bones could be healed with silk

Silk is an amazingly strong material, yet it also harmlessly biodegrades when left in the body. This has led to its use in experimental brain implants, heart patches, and even bio-electronics. According to a new study conducted by scientists at Tufts University School of Engineering and Beth Israel Deaconess Medical Center, it may now also find use in the production of better plates and screws used for securing broken bones.

Sensor system designed to help seniors who have fallen and can't get up

For seniors in general, falls can result result in broken hips or other serious injuries. For seniors living alone, however, there's also a good chance that they could end up lying on the floor for up to several hours before anyone else knows what's happened. User-triggered radio devices such as Life Alert are helpful up to a point, although they're not much good if the user isn't carrying them at the time, or if they get knocked unconscious. That's why a group of German companies are developing the automatic safe@home system. Read More
