Revolutionary Microchip Implanted in the Ear Could Soon Replace Chunky Conventional Hearing Aids

Cochlear implants have restored basic hearing to hundreds of thousands of people. However, the conventional device requires a microphone, speech processor and radio transmitter coil to be worn externally.

Many wearers feel self-conscious having their condition so publicly on display. It also prevents patients from activity like swimming.

Now a team led by the University of Utah have developed a tiny prototype that is implanted in the middle ear, which means it can't be seen.

Scientists Discover 'Master Switch' That Stops Cancer Cells from Growing

British scientists have discovered a new way to stop cancer in its tracks by manipulating a master switch responsible for cell growth.

The findings, published in the journal Cancer Cell, reveal how cancer cells grow faster by producing their own blood vessels.

Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumour.

These proteins are formed by a process of different parts of genes slotting together.

Scientists from the University of the West of England (UWE) and Bristol University studied tissues removed from kidney cancer patients at Southmead Hospital.

A purification device that cleans the air while asthma sufferers sleep dramatically reduces their symptons during the day, a study has concluded.

The temperature controlled laminar airflow treatment, called Protexo, filters out airborne triggers such as dust particles and mites, pet hairs and powders that cause irritiation and inflamation of the lungs.

Cervical Cancer Operation that Saves Women's Fertility

About 3,000 women a year are diagnosed with cervical cancer and for many the only option has been a hysterectomy.
