Noses, made in Britain: UK touts lab-grown organs


R&D – In a north London hospital, scientists are growing noses, ears and blood vessels in a bold attempt to make body parts in the laboratory.

“It’s like making a cake,” said Alexander Seifalian at University College London, the scientist leading the effort. “We just use a different kind of oven.” more> http://tinyurl.com/ovrb7m2

A Futuristic Look At The Nation Of San Francisco


By Chris Dannen, Michael Grothaus and Matthew Rosenberg – There’s no shortage of places to go for a run since the old highways were decommissioned when the hyperloop system came online; they’re now pedestrian and cyclist routes.

Taxi-goers are greeted by autonomous vehicles that take local roads, rendered traffic-free by synchronized driving and stoplight systems.

Visitors to the area who come by car are required to park outside the country’s limits and hyperloop in.

Gone are the rows of Paper Belt stores like you find in the United States and a lot of the vestigal public art.

There are no fast-food shops here (except Chipotle and Quizno’s, which according to local laws “don’t count”) and no hole-in-the-wall businesses; those have been relegated to cart- and truck-based businesses by soaring rent prices. more> http://tinyurl.com/omm56lo

Measuring photoactivation efficiency at the single molecule level


R&D – The ability to determine protein stoichiometry and monitor changes in the balance between monomeric, dimeric and multimeric proteins allows scientists to see the difference between a properly functioning cell and a diseased cell. For this reason, there is a great interest in being able to count proteins and determine their stoichiometry.

Photoactivatable flourescent proteins change their fluorescence property from dark to bright when exposed to light. Through the use of localization-based super-resolution microscopy, researchers are able to photoactivate, image, and follow these genetically encoded fluorescent proteins one at a time to study what is happening inside a cell at the molecular level. more> http://tinyurl.com/nhy4a7u

World’s Smallest Reed Switch Makes Technology Easier to Swallow


By Charles Murray – Known as the RedRock MEMS (microelectromechanical systems) switch, the new product could serve in such applications because it measures just 1 mm x 1 mm square. In contrast, conventional reed switches typically measure at least 4 mm to 5 mm long, due to technical limitations in the manufacturing process.

The technology may be best suited to a device known as an ingestible endoscope, which, after being swallowed, uses video cameras to take pictures of a person’s gastrointestinal tract. Today, such pill-shaped endoscopes measure an unappetizing one-inch long by almost half an inch wide, making them difficult to swallow. A MEMS-based reed switch would significantly reduce the size of such devices. more> http://tinyurl.com/omq2znp

What unites Democrats? Republicans!


By Bill Schneider – Why the sudden surge of Democratic Party discipline in 2009 and 2010?

The answer: Republicans. The Tea Party’s radicalization of the GOP ended up splitting Republicans and unifying Democrats.

The issues dividing Democrats today are over interests rather than values.

If Republicans win control of the Senate this year, the pressure on Hillary Clinton to run will be irresistible. Because if Democrats don’t hold the White House, the legacies of the last two Democratic presidents will be obliterated. And Hillary Clinton was part of both administrations. more> http://tinyurl.com/qbhjspe
