A team of researchers from the University of Michigan has developed a new technique to aid bone repair, using polymer nano-shells to deliver microRNA molecules. The method could one day have a big impact on regenerative medicine, directing cells already present at injury sites to aid healing. read more

Kill Cancer With One Fifth the Dose

The chemotherapy drug paclitaxel is commonly used to treat breast, lung and pancreatic cancers, slowing their growth by preventing cancerous cells from replicating. But once administered the drug is attacked by the body’s defenses, necessitating larger doses that result in complications such as joint pain, diarrhea and an impaired ability to fend off other infections. Researchers have now discovered a way to sneak the drug through to the tumor with its entire payload intact, a technique that could make for more effective cancer treatments with fewer side effects. read more

Vision Correcting Contact Lense

The latest trial results showed that special contact lenses designed to reshape the eye’s curvature could be used like ‘braces’ to slow the development of short sightedness in children.

Findings published in published in the Advances in Ophthalmology And Visual Systems journal show that the lenses, which should be worn overnight, reshape the curve in the eye while the wearer sleeps.  read more

As the liquid metal dissolves it releases gallium ions, which the researchers say further boosts the effectiveness of anticancer drugs

Scientists are increasingly turning to nanoparticles in search of new ways to treat cancer. Tiny nanorobots that way 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

A research team led by scientists from the University of New South Wales (UNSW) 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

Engineers from Princeton University have developed power-generating rubber films that could be used to harness natural body movements such as breathing or walking in order to power electronic devices such as pacemakers or mobile phones. The material, which is composed of ceramic nanoribbons embedded onto silicone rubber sheets, generates electricity when flexed and is highly efficient at converting mechanical energy into electrical energy. read more
