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

New Cancer Killer White Blood Cells

Injecting white blood cells with a special protein transforms them in to ‘super natural killer cells’, that can wipe out cancer, experts have revealed.

The specially engineered cells have the ability to seek out diseased cells in lymph nodes, with one purpose: destroy them.

The breakthrough by biomedical scientists at Cornell University, could stop the disease in its tracks, by preventing it from spreading.

‘We want to see lymph node metastasis become a thing of the past,’ said Michael King, the Daljit S, and Elaine Sarkaria, professor of biomedical engineering and senior author of the paper. read more

Electronic Skin Can Detect Changes in Both Temperature and Pressure

The unique way in which our fingertips can detect changes in both temperature and pressure have been reproduced in an electronic ‘skin’.

In tests, the grooves in the e-skin were able to respond to water droplets running across them and could detect when a human hair was placed on their surface.

The breakthrough could be used to make more life-like prostheses or improve the accuracy of wearable sensors and medical diagnostic devices.

The electronic skin (illustrated) was developed by researchers at the Ulsan National Institute of Science and Technology, led by Professor Jonghwa Park. By adding composites made of a polymer and reduced graphene oxide, the films are able to detect touch and temperature using sensing electric charges

Though sufferers of heart attacks may survive the initial event, they cause permanent damage to the organ in the form of scar tissue, which affects its ability to pump blood. Scientists around the world are working on this problem, with hydrogels, human stem cells and even bioengineered tissue that sticks together like Velcro all offering possible solutions. read more
