Massachusetts Institute of Technology (MIT) researchers, working with scientists from Brigham and Women's Hospital, have developed a new way to power and communicate with devices implanted deep inside the human body.

The devices which are powered by a radio frequency waves which can safely pass through human tissues, could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.

While conducting tests on animals, the researchers found that the waves can power devices located 10 centimeters deep in tissue, from distance of 1 meter.

As many as 70 percent of women with the most common form of breast cancer may be able to skip chemotherapy, based on their score on a genetic test, researchers said Sunday.

The minister had earlier threatened not to pay the salaries of JOHESU members for the number of days they went on strike while some were not paid the April salary.

The antibiotic resistance crisis which is threatening to render many diseases untreatable is being fuelled not just by overuse of the drugs, but a fragile supply chain that is at risk of collapse, experts have warned.

The authors of a white paper by the Dutch non-profit organisation Access to Medicine say a lack of access to specific antibiotics can lead to less appropriate drugs being prescribed for an infection, or even the use of lower doses – both of which increase the risk of antibiotic resistance – as well as delay for treatment. What’s more, they say, low stocks can lead to price hikes and mean poor quality medicines become rife.
