"Tiny semiconductor particles known as "quantum dots" have been used in a sensor that could make for mobile phone cameras that outperform larger cousins."
DiscOU is a resources discovery engine relying on a semantic index of Open University Open Content. It semantically analyses the content of an online resource, and matches it by similarity to other existing Open University content to retrieve the most relevant pieces. It currently works with BBC programme pages, as demonstrated in the video below, as well as from text entered/pasted in the DiscOU alfa interface.

"According to the US Centers for Disease Control and Prevention's website: "Ricin works by getting inside the cells of a person's body and preventing the cells from making the proteins they need. Without the proteins, cells die... Death from ricin poisoning could take place within 36 to 72 hours of exposure, depending on the route of exposure (inhalation, ingestion, or injection) and the dose received."
Dr Simon Archer and his team at Surrey University were particularly interested in looking at the genes that were switched on or off in our volunteers by changes in the amount that we had made them sleep.
"We found that overall there were around 500 genes that were affected," Archer explained. "Some which were going up, and some which were going down."
What they discovered is that when the volunteers cut back from seven-and-a-half to six-and-a-half hours' sleep a night, genes that are associated with processes like inflammation, immune response and response to stress became more active. The team also saw increases in the activity of genes associated with diabetes and risk of cancer. The reverse happened when the volunteers added an hour of sleep.
So the clear message from this experiment was that if you are getting less than seven hours' sleep a night and can alter your sleep habits, even just a little bit, it could make you healthier
The oldest big cat fossils ever found - from a previously unknown species "similar to a snow leopard" - have been unearthed in the Himalayas.
The skull fragments of the newly-named Panthera blytheae have been dated between 4.1 and 5.95 million years old.
Their discovery in Tibet supports the theory that big cats evolved in central Asia - not Africa - and spread outward.
It was supposed to be the first great scientific discovery of the 21st Century - or so many researchers thought when they rushed down to the bookmakers to place bets at what were deemed at the time to be ludicrously generous odds.
The physicists believed that they were close to making the first direct detection of gravitational waves, the ripples in space-time generated by supernovas and coalescing neutron stars.
