In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The “molecular beacons,” which could advance tissue engineering research, light up when certain genes are expressed and don’t interfere with the development or operation of the stem cells.

PROVIDENCE, R.I. [Brown University] — A novel set of custom-designed “molecular beacons” allows scientists to monitor gene expression in living populations of stem cells as they turn into a specific tissue in real-time. The technology, which Brown University researchers describe in a new study, provides tissue engineers with a potentially powerful tool to discover what it may take to make stem cells transform into desired tissue cells more often and more quickly. That’s a key goal in improving regenerative medicine treatments. (more…)

Made in IBM Labs: Holey Optochip First to Transfer One Trillion Bits of Information per Second Using the Power of Light

• Researchers invent novel technique by fabricating tiny holes in a single quarter-inch chip to boost data transfer rates
• Until now, it was not possible to transport terabits of data for existing parallel optical communications technology
• New prototype compactly and efficiently delivers ultra-high interconnect bandwidth to power future supercomputer and data center applications

LOS ANGELES – 08 Mar 2012: IBM scientists today will report on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies. The report will be presented at the Optical Fiber Communication Conference taking place in Los Angeles.

With the ability to move information at blazing speeds – eight times faster than parallel optical components available today – the breakthrough could transform how data is accessed, shared and used for a new era of communications, computing and entertainment. The raw speed of one transceiver is equivalent to the bandwidth consumed by 100,000 users at today’s typical 10 Mb/s high-speed internet access. Or, it would take just around an hour to transfer the entire U.S. Library of Congress web archive through the transceiver. (more…)

NASA’s Kepler Confirms Its First Planet in Habitable Zone

PASADENA, Calif. — NASA’s Kepler mission has confirmed its first planet in the “habitable zone,” the region around a star where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets.

The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun. The planet is about 2.4 times the radius of Earth. Scientists don’t yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets. (more…)
