New biosensor can detect bacteria instantaneously

A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen.

Electrical circuit runs entirely off power in trees

There's enough power in trees for University of Washington researchers to run an electronic circuit, according to results to be published in an upcoming issue of the Institute of Electrical and Electronics Engineers' Transactions on Nanotechnology.

"As far as we know this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree," said co-author Babak Parviz, a UW associate professor of electrical engineering.

801.11n set for final approval, but the story's not over

802.11n has brought wired-equivalent speeds to wireless networking, but the industry won't be resting on its laurels when the standard receives final approval later this week."Power saving is a big chunk of that [the industry] is working on," according to Matthew Gast, chief strategist at Trapeze Networks and chair of the Wi-Fi Alliance's Wireless Network Management and Security Technical task groups.

Bug Eye Gives Troops Better Night Vision

Frontline troops will be able to see better in the dark using revolutionary new optical technology that's modelled on the eye of a tiny parasitic fly.

Engineers at BAE Systems have developed the new 'bug eye' technology following several months of research examining the eye mechanisms of the Xenos peckii - a parasitic fly that lives on a wasp. The tiny bug has 50 separate lenses in each eye. Each lens produces an individual image, which are meshed together to form a single large panoramic image in its brain.

Quantum Chip Helps Crack Code

Experimental chip does part of code-cracking quantum algorithm.

Using four photons that pass through a sequence of quantum logic gates, the optical circuit helped find the prime factors of the number 15. While the researchers showed that it was possible to solve for the factors, the chip itself didn’t just spit out 5 and 3. Instead, it came up with an answer to the ”order-finding routine,” the ”computationally hard” part of Shor’s algorithm that requires a quantum calculation to solve the problem in a reasonable amount of time.
