Engineers at the University of Washington have developed a new “ambient backscatter” wireless communication scheme that allows two devices to communicate with each other by reflecting ambient TV and cellular transmissions — batteries not required.

Bacteria communicate by touch, new research suggests

bacteria communicate

Associate professor Christopher Hayes and graduate student Christina Beck researching.

What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions…

Human Energy Recycle System

human-energy 1234

Going green is all the rage these days, which is why the Human Energy Recycle System, if implemented, could very well turn the way we live upside down in a good way. Comprising of wearable contraptions known as Solution Units, these come with a battery that can store harnessed energy, where said batteries can be removed to charge other devices such as cellphones and portable media players later on.

iPhones Overload AT&T, Angering Customers

03att01-650

AT&T monitors its network from its operations center

Slim and sleek as it is, the iPhone is really the Hummer of cellphones.

It’s a data guzzler. Owners use them like minicomputers, which they are, and use them a lot. Not only do iPhone owners download applications, stream music and videos and browse the Web at higher rates than the average smartphone user, but the average iPhone owner can also use 10 times the network capacity used by the average smartphone user.

Transplanted Stem Cells Undo Birth Defects

Transplanted Stem Cells Undo Birth Defects 

 Neural stem cells, tagged green with a fluorescent dye, have been transplanted among the brain cells (red) of a mouse born with brain damage after its mother was given heroin during pregnancy.

By injecting stem cells directly into the brain, scientists have successfully reversed neural birth defects in mice whose mothers were given heroin during pregnancy. Even though most of the transplanted cells did not survive, they induced the brain’s own cells to carry out extensive repairs.

Faster Wireless to Compete with Speed of Fiber

Faster Wireless to Compete with Speed of Fiber

 Researchers at Battelle used off-the-shelf optical telecommunication
components to create a faster millimeter-wave device.

There’s no shortage of demand for faster wireless, but today’s fastest technologies–Wi-Fi, 3G cellular networks, and even the upcoming WiMax–max out at tens or hundreds of megabits per second. So far, no commercial wireless system can beat the raw speed of optical fiber, which can carry tens of gigabits per second.

A Glowing Protein Shows How We Make Memories

A Glowing Protein Shows How We Make Memories

A new strain of genetically engineered mice has allowed researchers to pinpoint, for the first time, the precise cellular connections that form as a memory is created. By tracing a protein tagged to glow fluorescent green as it migrates through individual neurons, from the cell body out through the branching dendrites, the researchers could see exactly which synapses–connections to other neurons–were involved when the mice learned to fear an electric shock.
