Seaweed is widely considered to be a health food. Bacon, on the other
hand ... well, bacon isn't. There may yet be hope for pork belly lovers
around the world, however. Scientists at Oregon State University (OSU)
have patented a lab-bred strain of dulce seaweed, that they claim has "a
strong bacon flavor" when fried.
When Google proposed its Open Web of Things initiative last December, it was seeking to increase interoperability, security, and an elegant user interface in the global movement towards connected smart devices. The company has awarded half a million dollars towards Carnegie Mellon University to develop its campus and eventually Pittsburg, PA into a "living lab" of cheap and ubiquitous sensors, integrated apps, and user-developed tools to work towards Google's vision of an integrated machine future.
A team of scientists, led by the University of Washinton's Dr Chuck Murray, has successfully crowdfunded a project to sequence the genome of the black rhinoceros – a species that's been poached to near extinction. The effort is an important step in the conservation of the species, of which there are barely more than five thousand remaining.
If the thought of using a person's brainwaves to control a machine isn't quite enough to make the mind boggle, then mixing signals from multiple brains for the same purpose might just do the job. This far-fetched field of neuroscience is edging ever closer to real-world technology, with a number of recent research efforts achieving significant advances, with mind-controlled drone flight just one example. The latest step forward in this area sees the brains of separate animals hooked up and their combined motor and sensory information used for things like controlling a virtual arm, pattern recognition and even predicting the weather.
In yet another first for graphene, physicists from the University of California, Berkeley, have employed this versatile material to
create ultra-thin, lightweight ultrasonic microphones and speakers that
enable high-quality, two-way communication in the audio range normally used by the likes
of bats and dolphins.
University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This find could represent the discovery of an entirely new class of materials, challenging our current understanding of how metals behave.
A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy and transforms it into either electricity or chemical energy used to split water and produce hydrogen for use in fuel cells. In an advance that could help this clean energy source play a stronger role within the smart grid, researchers at the University of Texas, Arlington have found a way to store the electricity generated by a PEC cell for extended periods of time and allow electricity to be delivered around the clock.
In quantum cryptography, encoding entangled photons with particular spin states is a technique that ensures data transmitted over fiber networks arrives at its destination without being intercepted or changed. However, as each entangled pair is usually only capable of being encoded with one state (generally the direction of its polarization), the amount of data carried is limited to just one quantum bit per photon. To address this limitation, researchers have now devised a way to "hyperentangle" photons that they say can increase the amount of data carried by a photon pair by as much as 32 times.
Researchers at the University of California, Davis and Berkeley have managed to miniaturize low-depth ultrasound technology to create a fingerprint sensor that can scan your finger in 3D. This low-power technology, which could improve on the robustness of current-generation capacitive scanners, could soon find its way to our smartphones and tablets.
There are already several methods of identifying cattle –
branding, ear tags, tattooing and ear notching all come to mind. Now,
however, Egyptian scientists are working on a new biometric system that's less
invasive and more difficult to thwart: electronic muzzle-printing.
