It was only last month that futurists Elon Musk and Stephen Hawking warned about the dangers of intelligent robots, and a new research project led by the University of Cambridge won't do much to put their minds at ease. Scientists have created a mother robot that can not only build its own children robots, but mimic the process of natural selection to improve their capabilities with each generation.
As with every form of the deadly disease, early detection of oesophageal cancer is critical to recovery. The current approach of detecting the cancer through biopsy can be a little hit and miss, so the University of Cambridge's Professor Rebecca Fitzgerald and her team have developed what they claim to be a more accurate tool for early-diagnosis. Billed as "a pill on a string," the Cytosponge is designed to scrape off cells from the length of the oesophagus as it is yanked out after swallowing, offering up a much larger sample for inspection of cancer cells.
