Researchers at the University of Illinois at Urbana-Champaign (Champaign, IL) have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz (GHz). By internally connecting the base and collector of this light-emitting transistor, they created a new form of light-emitting diode (LED) that modulates at up to 7 gigahertz, breaking a previously announced record of 3.6 GHz for a plasmonic LED.

Funding The Machine That "Might Save The World"
General Fusion, the Canadian duo who hope to produce a cold fusion power plant for perhaps a tenth the cost of other such promised projects, just got a $12 million shot in the arm.
According to the Toronto Star, the four-year grant comes from a non-profit called Sustainable Development Technology Canada (SDTC). However, SDTC will only provide the grant if General Fusion can match it with $28.7 million in private investment. Considering General Fusion only raised $6 million in its last round of funding, that sounds pretty steep.

Sparton to deliver sonobuoy tech to Navy
Sparton Corp. has been contracted to support the U.S. Naval Antisubmarine Forces with sonobuoy acoustic signal receive array technologies.
Sparton announced it was selected for a subcontract to supply its sonobuoys for the Navy as part of the company's Erapsco joint venture with Undersea Sensor Systems Inc.
Under the $19.3 million subcontract, Sparton produce subassemblies systems for approximately 7,320 of its AN/SSQ-101A (Q-101A) sonobuoys. Officials say the sonobuoys detect potentially hostile submarines' acoustic emissions.

Suspect Detection Systems completes R and D
Suspect Detection Systems Inc. announced the successful completion of Israeli-based research and development of its Cogito4M military grade technology.
Suspect Detection Systems has completed a two-year research and development project on its Cogito4M technology. Officials say the Cogito4M is a portable interrogation technology with multilingual tools developed to ensure soldiers in the field get accurate identification of terrorist suspects for detention.

Radioactive threat detectors fail tests
The U.S. Congress's watchdog agency has recommended further testing of next-generation radiation detectors designed to increase security against radioactive threats at the country's ports of entry after tests produced lackluster results.
The U.S. Department of Homeland Security had hoped to replace its existing detectors with the new advanced spectroscopic portal radiation detection monitors.
But the U.S. Government Accountability Office was not impressed with the advantages of the new high-tech detectors given their price tag or the rigor of the tests themselves.

Perfect pitch
Communications company Orange has revealed its vision of what a high-tech tent might look like in the future.
Rather than relying upon solar panels to provide power for the tent, the designers have based their concept around the futuristic idea of using 'solar threads' that would be woven into the fabric of the tent.
The tent’s solar shell uses the idea to full effect with three directional glides which can be moved throughout the day to maximise its solar efficiency, capturing the optimum amount of energy that can be used throughout the tent.

Ebrake contract
Meggitt Aircraft Braking Systems has won its first commercial contract for Ebrake: its advanced electric braking system that was successfully flight tested on a Bombardier demonstrator aircraft last year.
Meggitt’s electric brakes and control system will be installed on the Bombardier CSeries family of 110- to 130-seat aircraft launched in 2008 and due to enter service in 2013.

Reverse-Engineering the Quantum Compass of Birds
Scientists are coming ever closer to understanding the cellular navigation tools that guide birds in their unerring, globe-spanning migrations.
The latest piece of the puzzle is superoxide, an oxygen molecule that may combine with light-sensitive proteins to form an in-eye compass, allowing birds to see Earth’s magnetic field.
“It connects from the subatomic world to a whole bird flying,” said Michael Edidin, an editor of Biphysical Journal, which published the study last week. “That’s exciting!”

NGC Submits Proposal to Revolutionize GPS Operations
The Northrop Grumman Corporation (NYSE:NOC) Global Positioning System (GPS) Advanced Control Segment (OCX) team on June 20 submitted its proposal to the U.S. Air Force for the OCX Phase B contract.
The Northrop Grumman proposal draws upon the team's decades of navigation experience, years of OCX risk reduction activities and a successful Phase A demonstration performance. The Northrop Grumman team has worked hand-in-hand with the Air Force GPS Wing over the course of the 22-month Phase A contract and has now provided a comprehensive plan, cutting-edge technologies and innovative ideas for the advanced control segment. GPS is fully embedded into U.S. military operations, American commercial practices and civilian uses.

Toyota plans fuel-cell car by 2015
Toyota Motor, the world’s top automaker, plans to roll out a fuel-cell car by 2015 in its push to stay ahead in the global race for green autos, vice president Masatami Takimoto said.
His comments came at a shareholders’ meeting at Toyota headquarters in Aichi prefecture in response to an investor’s question about the company’s outlook on zero-emissions technology, but he declined to elaborate.
Fuel-cell technology is considered a cutting-edge solution to reducing carbon dioxide emissions as it generates electricity by combining a fuel — usually hydrogen — with oxygen, and therefore only emits water.

IBM supercomputer reuses heat to warm buildings
IBM’s latest green venture is a highly efficient supercomputer that uses water to siphon off waste heat, and then uses the excess energy to warm up a building.
High-tech giants from Microsoft to Google are eager to cut the huge amounts of power used to run their data centers, particularly now that the recession has companies leaving no stone unturned to slash costs and global warming is driving them to think green.

IBM 'Roadrunner' Holds World's Fastest Computer Crown
IBM (NYSE: IBM)'s Roadrunner supercomputer at the Los Alamos National Laboratory held on to its title as the world's fastest computer, followed once again by Cray's Jaguar.
The biannual Top500 list, released Tuesday at the 2009 International Supercomputing Conference, also saw two new systems enter the top 10. Both systems -- the IBM BlueGene/P called Jugene and the Juropa, which is built from Novascale and Sun Microsystems Sun Blade x6048 server -- were at Forschungszentrum Juelich in Germany. The Jugene achieved 825.5 teraflops and the Juropa 274.8 teraflops. A teraflop is a trillion floating point operations per second.

New Washing Machine Uses Plastic Instead of Water
Xeros is working on a new breed of washing machines that will use only a cup of water per load, relying on reusable nylon beads to trap dirt and stains for hundreds of washes.
The U.K.-based Xeros has been testing the machine for three years. Through a partnership with GreenEarth Cleaning, the machines will soon be sold in North America. The initial target will be commercial dry cleaners and laundromats.

Altierre Sees Opportunity for Temperature Tags
Altierre, a San Jose, Calif., provider of wireless solutions for retailers, has released a new temperature-sensing product designed to help stores monitor the conditions under which food is stored or displayed. The system can be installed in a matter of hours, with a typical cost to a supermarket of approximately $15,000, including software, sensor tags and interrogators. Alternatively, it can be added to an Altierre wireless shelf tag system already installed, by simply deploying the sensor tags, priced at less than $10 apiece.
