Doctor visits may soon get a bit less scary with a new needle-free injector able to deliver precise doses of medicine with different levels of force. The injector will use a Lorentz-force actuator to deliver a high-pressure jet of medicine through the skin without the need for a needle. The actuator will work through a powerful magnet surrounded by a coil of wire attached to a piston inside the drug ampoule. An applied current will interact with the magnetic field to push the...

The new bandages will do more than cover a wound; they will also make it easier to potentially save a life by becoming a bone marrow donor. The packets of bandages will include a registry kit, sterile swabs, and a postage paid envelope. Before bandaging, users will swab some blood from their wound and mail it to the DKMS bone marrow donation center to register for bone marrow donation.

Researchers have discovered a new protein that regulates the development of brown fat, which could lead to new methods of controlling obesity. The protein, called BMP8B, controls brown fat by regulating its heat producing activity, which could make it ideal for creating new weight control therapies. In research, brown fat cells treated with BMP8B responded strongly to nervous system activation, and mice treated with BMP8B lost more weight than non-treated mice. This is due to the...

The new device will detect when you're feeling overworked and modify the work load to remove some of the stress. The device will consist of a functional near-infrared spectroscopy (fNIRS) sensor worn strapped to the forehead and able to analyze brain patterns to determine when a person is multitasking. The system could eventually be used to warn people when they appear distracted or aid workers who typically handle several tasks at once.

A new wristband will be able to diagnose and even predict potentially dangerous seizures. The wristbands will measure conductance, or how easily electrical current will pass through the skin. The skin conductance rises dramatically before and during a seizure, and the higher the conductance, the longer it takes for the brain to return to normal. The wristbands will be used to monitor people with seizure conditions, noting their intensity and possibly calling for help if the...

A new nanocomposite material will be used to fill cavities as well as eliminate any bacteria remaining in the tooth. The material will be made up of silver nanoparticles and calcium phosphate nanoparticles. The silver will kill off any remaining bacteria while the calcium phosphate will help to rebuild the tooth's structure. The dangers of silver nanoparticles are still unknown, and integrating the silver in the material will help to reduce the possible risks of ingestion.
