New password in a heartbeat: Researchers propose touch-to-access security for implanted devices
Pacemakers, insulin pumps, defibrillators and other implantable medical devices often have wireless capabilities that allow emergency workers to monitor patients. But these devices have a potential downside: ...
First mammalian 'cell phone'
(Phys.org)—Researchers from ETH Zurich have quite literally created a "cell phone": they have reprogrammed mammalian cells in such a way that they can "phone" each other via chemical signals.
3-D images show flame retardants can mimic estrogens
By determining the three-dimensional structure of proteins at the atomic level, researchers at the National Institutes of Health have discovered how some commonly used flame retardants, called brominated ...
New physical phenomenon on nanowires seen for the first time
Very tiny wires made of semiconducting materials – more than one thousand times thinner than a human hair – promise to be an essential component for the semiconductor industry. Thanks to these tiny nanostructures, ...
Why is language unique to humans?
New research published today in Journal of the Royal Society Interface suggests that human language was made possible by the evolution of particular psychological abilities.
Researchers at Toshiba design quantum network for secure communications
Professor brings access to previously untapped higher frequency bandwidth
Society's increasing technology use and data consumption is causing an information bottleneck, congesting airwave frequencies and sending engineers searching for access to higher capacity bandwidths.
Improving the flow of the fibre optic freeway
Monash University researchers have played a pivotal role in the invention of an energy-efficient method of increasing the data capacity of optical networks to the point where all of the world's internet traffic ...
Researchers test quantum encryption hacking risk
(Phys.org) —Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends ...
Ants have an exceptionally 'hi-def' sense of smell
The first complete map of the ants' olfactory system has discovered that the eusocial insects have four to fives more odorant receptors—the special proteins that detect different odors—than other insects.
Plants use underground networks to warn of enemy attack
Plants use underground fungal networks to warn their neighbours of aphid attack, UK scientists have discovered.
International Space Station to beam video via laser back to Earth
(Phys.org) —A team of about 20 working at NASA's Jet Propulsion Laboratory in Pasadena, Calif., through the lab's Phaeton early-career-hire program, led the development of the Optical Payload for Lasercomm ...
Roots of language in human and bird biology
The genes activated for human speech are similar to the ones used by singing songbirds, new experiments suggest.
Can video streaming over mobile broadband networks be improved?
Due to the increase in smartphone video applications, mobile video traffic is rising significantly. New research has shown how videos can be better transmitted over wireless links such as Wi-Fi and 4G.
