Researchers have found that graphene-based heat pipes can help solve the problems of cooling electronics and power systems used in avionics, data centres, and other power electronics. «Heat pipes are one of the most efficient tools for this purpose, because of their high efficiency and unique ability to transfer heat over a large distance,» says…

Researchers and surgeons have devised a new type of amputation surgery that can help amputees better control their residual muscles and receive sensory feedback. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as reduction of limb pain, the researchers say. In most amputations, muscle pairs that control the…

Metal-free antennas made of thin, strong, flexible carbon nanotube films are as efficient as common copper antennas, according to researchers. The Rice lab of chemical and biomolecular engineer Matteo Pasquali tested antennas made of «shear-aligned» nanotube films. The researchers discovered that not only were the conductive films able to match the performance of commonly used…

Hitting a material with laser light can produce a flash of superconductivity — the ability to carry electric current with no loss — and may offer a path toward room-temperature conductivity. In the case of a superconducting material known as yttrium barium copper oxide, or YBCO, experiments have shown that under certain conditions, knocking it…

Astronomers have obtained the deepest and sharpest images to date of the region around the supermassive black hole at the center of our galaxy. The new images zoom in 20 times more than what was possible before the VLTI and have helped astronomers find a never-before-seen star close to the black hole. By tracking the…

The increasing number of devices connected over wireless networks is causing channels of information flow to be congested with heavy information traffic. But, these devices are resource-constrained and cannot support existing decongestion techniques. In a new study, scientists have applied a certain machine-learning technique that can enable even these devices to adaptively choose freer channels…

A research team has recorded the world’s fastest internet speed from a single optical chip of 44.2 Terabits per second. Published in the journal Nature Communications, these findings have the potential to not only fast-track the next 25 years of Australia’s telecommunications capacity, but also the possibility for this home-grown technology to be rolled out…

Researchers recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.…

Researchers have discovered the remains of a nova in a galactic globular cluster, located near the center of Messier 22. The finding, using modern instruments, confirms one of the oldest observations of an event outside the solar system. «The position and brightness of the remains match an entry from 48 BC in an ancient collection…

The process retains properties of fibers at a higher rate than previous methods, demonstrating a retention strength of up to 90 percent. Recycling of composite materials could be up to 70 percent cheaper and lead to a 90-95 percent reduction in CO2 emissions compared to standard manufacturing. This is the case with carbon fibre reinforced…
