Universities must investigate measures, including random dope testing, to tackle the increasing use of cognitive enhancment drugs by students for exams, a leading behavioural neuro scientist warns.
Student use of drugs, such as Ritalin and modafinil, available over the internet and used to increase the brain’s alertness, had “enormous implications for universities”, said Barbara Sahakian, a professor of clinical neuropsychology at Cambridge University’s psychiatry department.
PageRank, the generally accepted metric of, among other things, how often a page is linked to, is only a small part of the larger story at Google. Talking to Google’s engineers and tracing the history of publicly announced search features, Levy discovers that a good deal of what Google has learned about search comes from the searchers themselves.
Take, for instance, the way Google’s engine learns which words are synonyms. “We discovered a nifty thing very early on,” Singhal says. “People change words in their queries. So someone would say, ‘pictures of dogs,’ and then they’d say, ‘pictures of puppies.’ So that told us that maybe ‘dogs’ and ‘puppies’ were interchangeable. We also learned that when you boil water, it’s hot water. We were relearning semantics from humans, and that was a great advance.”
The Copenhagen Wheel is a new emblem for urban mobility. It transforms ordinary bicycles quickly into hybrid e-bikes that also function as mobile sensing units. The Copenhagen Wheel allows you to capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost. It also maps pollution levels, traffic congestion, and road conditions in real-time.
The site activates your webcam automatically; when you click “start” you’re suddenly staring at another human on your screen and they’re staring back at you, at which point you can either choose to chat (via text or voice) or just click “next,” instantly calling up someone else. It’s the anti-Facebook, pure social-media shuffle. Once you dive in, there’s no way to manage the experience—to filter users, search for friends, or backtrack and reconnect with someone you chatted with an hour ago. There’s only the perpetual forward motion of “next.
Polar Rose has developed a software using flickr images to be able to recognize faces, where in which you can now automatically tag photos of your friends and be able to identify them during presentation and pull up their contact information via social networking sites.
