DNA 'Timebomb' vaccine fights cancer  - BBC  A delayed-release system could help produce more effective vaccines against a number of diseases, including cancer. Scientists from Massachusetts Institute of Technology encased their "DNA vaccines" in biodegradeable spheres. They do not break down and release the vaccine until they are carried to key locations such as the lymph nodes. DNA vaccines, which instead of a whole virus contain fragments of genetic material from a virus or bacteria. It is possible that they could deliver a life-long immunity to certain infections for which there is a vaccine, but only one which gives a few year's protection.
HD DVD discs Heat is on: The battle for the next generation of DVDs has begun  - BBC  A war is being fought behind the scenes for control of the DVD player in your living room. On one side is the HD-DVD, (High Definition DVD), backed by a group led by Toshiba and NEC. The HD-DVD discs can hold up to 30GBs and are more like an upgrade of current DVD technology. The HD-DVD grouping is up against a powerful consortium of electronics giants, including Sony, Philips, Matsushita and Samsung, who back the incompatible Blu-ray format. The Blu-ray discs can hold up to 50GBs and are based on blue/violet lasers. "What is needed is a quantum leap in performance," Philips boss Frans Van Houten told a recent forum .

The ward-round robot with a patient

Robodocs: Dr R2D2 will see you now... How hospitals of the future might look  - BBC  A patient lies in a hospital bed, waiting to hear if her operation has been a success. But in the hospitals of tomorrow, it may not be a doctor who brings her the news. Instead, a robot could glide between the beds, allowing doctors to talk to their patients from home - or even from another country. And this isn't a high-tech fantasy - doctors in the US are already using a robot as part of their team. Dr Louis Kavoussi is one of those at the forefront of robot medicine. The doctor, based at the Johns Hopkins Hospital, Baltimore, Maryland, uses the ward-round robot to talk to patients from home. He envisages a time where patients lie in airline-style seat beds, with monitors on which they can watch TV and log on to the Internet, and via which doctors can asses them at any time of the day or night. Doctors may even be less involved in operations. Patients could be scanned, and the information sent directly to the "surgeon" robot, which could make an incision in exactly the right spot. Robots are already being used to perform keyhole surgery, where precision is crucial. Last week, surgeons at St Thomas's Hospital in London operated the controls of a robot carrying out an operation on a kidney model in the US.
