Tiny nanocubes help scientists tell left from right
New method could improve drug development, optical sensors and more UPTON, NY-In chemical reactions, left and right can make a big difference. A “left-handed” molecule of a particular chemical composition could be an effective drug, while its mirror-image “right-handed” counterpart could be completely inactive. That’s because, in biology, “left” and “right” molecular designs are crucial: […]
RFIC platform boosts the transmission range of devices to up to 15 kilometers
Semtech Corporation introduced the SX1272, the first product in a new long-range RFIC platform that boosts the transmission range of the devices to up to 15 kilometers (km).

Renewable energy: World invests $244 billion in 2012; shift to developing countries underway
Installed capacity continues to grow as solar prices drop 30-40 percent, new wind installations surge For only the second time since 2006, global investments in renewable energy in 2012 failed to top the year before, falling 12% mainly due to dramatically lower solar prices and weakened US and EU markets. However, 2012 was the second […]
