Terahertz radiation could speed up computer memory by 1000 times
One area limiting speed in personal computing speed is memory -- specifically, how quickly individual memory cells can be switched, which is currently done using an external magnetic field. European and Russian scientists have proposed a new method using much more rapid terahertz radiation, aka "T-rays," the same things used in airport body scanners. According to their research, published in the journal Nature, swapping out magnetic fields for T-rays could crank up the rate of the cell-resetting process by a factor of 1000, which could be used to create ultrafast memory.
Researchers use T-rays to look inside of broken microchips
Terahertz radiation, or T-rays, can do some really incredible stuff. It can be used to scan for tumors and bombs build ultrafast wireless networks and see through solid objects. As an imaging technology, however, T-ray cameras have always had a resolution limitation. Well, they used to. Researchers at the University of Exter has developed a new terahertz camera that can see at a microscopic level -- and they want to use it to find defects in microchips.
T-rays produce 3Gbps short-range wireless, make WiFi pout in the corner
The last time we saw T-rays, they were busy scanning bodies for tumors and security threats. Six researchers from the Tokyo Institute of Technology are now aiming the terahertz-level frequencies at a less organic target: fast wireless. Running at 542GHz, a rate that makes 60GHz ultra wideband look pokey, the scientists are sending data through the ether at about 3Gbps. The speed isn't as fast as the 7Gbps peak of WiGig, and the bandwidth runs dry at just 33 feet away, but it comes out of a resonant tunneling diode measuring 0.04 square inches -- definitely small enough to fit into a smartphone. The speed could magnify using higher frequencies and power levels, too, with 100Gbps being the dream. Knowing that it can take years for academic papers to translate to real products, we're not holding our breath for T-ray routers anytime soon. Still, the technology could make wideband a realistic option for handhelds and put the mere 1.3Gbps of 802.11ac WiFi to shame. [Thanks, Andrew.

Scientists produce stronger T-rays, bring Tricorders closer to reality
A group of scientists from Imperial College London and Singapore's Institute of Materials Research and Engineering (IMRE) have developed a new technique that could have far reaching impacts for Star Trek fans everywhere. It all involves something known as Terahertz (THz), or T-rays: electromagnetic rays that have already been used in full-body airport scanners and have the potential to be used across a much broader range of medical and environmental applications. Because every molecule can be uniquely identified within the THz range, these T-rays can be used to pick up on cancerous cells and other biological matter, perhaps even within a Tricorder-like scanner. Now, Imperial College's Stefan Maier and his team of scientists say they've found a way to create a stronger beam of T-rays, using so-called "nano-antennas" to generate an amplified THz field. In fact, this field can produce about 100 times more power than most other THz sources, which could allow for sharper imaging devices. "T-rays promise to revolutionize medical scanning to make it faster and more convenient, potentially relieving patients from the inconvenience of complicated diagnostic procedures and the stress of waiting for accurate results," Maier explained. "Thanks to modern nanotechnology and nanofabrication, we have made a real breakthrough in the generation of T-rays that takes us a step closer to these new scanning devices."

Mini-Z T-ray imaging device takes home the gold
We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.[Via Physorg]
