Rapid bacterial infection test reduces antibiotic use

11/08/2016

Researchers from the Oxford University Clinical Research Unit in Vietnam have shown that using a rapid (5-minute) test can reduce antibiotic misuse for respiratory infections. Cutting the number of unnecessary antibiotic prescriptions is a key way to prevent the spread of antibiotic-resistant infections.

Microfluidic device to study electric field cancer therapy

14/07/2016

Researchers at MIT's research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.

Researchers use gelatin to grow stronger muscles

05/07/2016

USC researcher Megan L. McCain and colleagues have devised a way to develop bigger, stronger muscle fibers. But instead of popping up on the bicep of a bodybuilder, these muscles grow on a tiny scaffold or "chip" molded from a type of water-logged gel made from gelatin.

Faster detection of pathogens in the lungs

27/06/2016

What used to take several weeks is now possible in two days: Thanks to new molecular-based methods, mycobacterial pathogens that cause pulmonary infections or tuberculosis can now be detected much more quickly. Time-consuming bacteria cultures no longer need to be taken from the patient samples, meaning that a suitable therapy can be started quickly.
