  • Gallium nitride transistors promise brighter future for LEDs

    Researchers from the Fraunhofer Institute for Applied Solid State Physics have announced a new advance in gallium nitride transistors that could help make the light-emitting diode (LED) the commercial light source of the future.

  • Kepler’s five-year tally: 961 new planets

    It’s been five years since NASA’s 0 million Kepler Space Telescope was launched to look for planets beyond our Solar System and while the quest to find a twin for Earth has so far been fruitless, Kepler’s observations have revealed our galaxy to b...

  • Bacteria brews biofuel with potential to replace high-energy rocket fuel

    Researchers at the Georgia Institute of Technology and the US Department of Energy’s Joint BioEnergy Institute have engineered a bacterium that could yield a new source of high-energy hydrocarbon fuel for rocketry and other aerospace uses.

Researchers at the Georgia Institute of Technology and the US Department of Energy’s Joint BioEnergy Institute have engineered a bacterium that could yield a new source of high-energy hydrocarbon fuel for rocketry and other aerospace uses. High-energy, specific-use hydrocarbon fuels such as JP-10 can be extracted from oil, along with more commonly used petroleum fuels, but supplies are limited and prices are high – approaching US$7 per liter. That’s where the new bacterium, engineered by Georgia Tech scientists Stephen Sarria and Pamela Peralta-Yahya, could come in.  Read More

It’s been five years since NASA’s $600 million Kepler Space Telescope was launched to look for planets beyond our Solar System – so-called exoplanets – and while the quest to find a twin for Earth has so far been fruitless, Kepler’s observations have revealed our galaxy to be full of worlds potentially able to support life.  Read More

Gallium nitride transistors enabled the compact design of this 2090 lumen retrofit LED lam...

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting. But that’s about to change. Fraunhofer researchers are developing a new, more economical means of making the high-performance gallium nitride transistors needed for the LED’s high-efficiency driver.  Read More
