Lab-grown burger tasted at event in London, said to require ketchup
A couple of tasters, who claim they're unpaid and impartial, are currently chomping their way through some very expensive artificial flesh at a publicity event in London. According to the BBC's science correspondent Pallab Ghosh, who is also at the gathering, the main feedback so far is that the meat -- which is presented as a burger -- isn't as juicy or tasty as the real thing, mainly because it's totally lean. The substance was grown by a team at the University of Maastricht, with a spot of funding from none other than Google visionary Sergey Brin, who believes the technology is on the "cusp of viability" as a solution to animal welfare issues. Lead researcher Prof. Mark Post doesn't seem too disheartened by the tasters' comments, but says he's working to improve flavor. At a current cost of $325,000 per patty, people are going to expect something special regardless of the ethical or ecological arguments -- and some cajun spices probably won't cut it.
Burger built in lab costs $325,000 to produce, 'tastes reasonably good'
Dr. Mark Post of the University of Maastricht has carefully cultivated the most expensive burger you will probably never eat. Using stem cells and the science of tissue engineering, Post and his team have developed a method for creating an edible product called in-Vitro meat, which they hope to present in burger form at a special event in London next month. Despite the burger's artificial origins, Post claims it "tastes reasonably good." The in-Vitro burger was designed as a proof-of-concept to address the problem of a growing global population with a rapidly dwindling food supply. Even so, it's unlikely that lab-grown meat will be as widely available as White Castle anytime soon since creating it is an expensive, time-consuming process -- a single burger costs about $325,000 to produce. Each pricey patty begins its life as cells sourced from the necks of slaughterhouse cows, which are then developed in a growth serum comprised of fetal calf stem cells. After three weeks, those cells divide into a strip of meat, about half an inch long. Combine about 20,000 of those tissue strips and you've got yourself a burger. If that doesn't get your taste buds tingling, we don't know what will.
New system lets you type with your brain using MRIs
This isn't mind reading, per say. Instead Bettina Sorger, Joel Reithler, Brigitte Dahmen and Rainer Goebel at Universiteit Maastricht have figured out a way to monitor the flow of blood in the brain and associate the images captured using an MRI with the letters of the alphabet. The whole system takes about an hour to learn and configure for each individual. Trials focused on healthy individuals, but clearly its the paralyzed and people suffering from diseases like ALS that have the most to gain. Sorger hopes to enable "locked-in" patients to finally be able to communicate with the outside world by thinking out letter at a time. Obviously, patients aren't going to be able to install an MRI in their homes, much less lug one around with them. The data collected could be used to finely tailor less accurate but more portable systems for patients that monitor electrical or light signals.
