Graphene shows promise for super strong dental fillings

A team of researchers from four institutions located in Romania and St. Kitts have worked together to determine whether graphene could be used to create more durable dental materials. They worked to test how toxic different forms of the material were to teeth, with promising results.Read More

Liquid metal "Nano-Terminators" could signal judgement day for cancer

Scientists are increasingly turning to nanoparticles in search of new ways to treat cancer. Tiny nanorobots that wade through the bloodstream and microscopic particles that blow up diseased cells are a couple of menacing examples. But none sound quite so ominous as a new technique under development at North Carolina State University (NCSU). Its researchers have designed liquid metal particles they describe as "Nano-Terminators" that latch onto cancer cells to more effectively deliver drugs that kill them off.Read More

Kinect measures body thickness to lessen radiation exposure from X-rays

The depth-sensing capabilities of the Microsoft's Kinect has seen it put to use in a number of unexpected applications, such as helping Parkinson's sufferers to walk and the visually impaired to practice yoga. Scientists now claim to have expanded the applications for the gaming technology to include a more precise approach to X-ray imaging, which they say can limit exposure to radiation by measuring the thickness of a subject's body parts.Read More

Scientists identify protein central to cognitive decline associated with Alzheimer's disease

A study from researchers at the Gladstone Institutes in San Francisco has examined the protein BRCA1, using a combination of tests on laboratory mice and human brain tissue to determine that the protein is central to learning and retaining memories. The work highlights the importance of the protein in relation to the cognitive decline associated with Alzheimer's disease, and could help in the development of future treatments.Read More

Study shows how Alzheimer's disease destroys brain cell connections early on

A research team led by scientists from the University of New South Wales in Australia has studied the mechanism by which connections in the brain are destroyed in the early stages of Alzheimer's disease. The findings represent another angle of attack in the ongoing battle to find a cure for the widespread degenerative condition.Read More

Functional vocal cord tissue grown in the lab for first time

For the first time, scientists have successfully grown vocal cords in the lab, with tests showing the engineered tissue to be functional, with the ability to transmit sound. While the research is just the first step on a long path towards clinical use, the results are very promising, providing a solid basis for future study.Read More
