Scientists use stem cells from frogs to build first living robots

January 16th, 2020 at 1:14 pm » Comments Off

Researchers foresee myriad benefits for humanity, but also acknowledge ethical issues Be warned. If the rise of the robots comes to pass, the apocalypse may be a more squelchy affair than science fiction writers have prepared us for. Researchers in the US have created the first living machines by assembling cells from African clawed frogs […]



New battery tech can keep your smartphone charged for five continuous days

January 9th, 2020 at 12:01 pm » Comments Off

h can keep your smartphone charged for five continuous days The new high-capacity lithium-sulfur batteries can pave way for cheaper electric cars and solar grids. Researchers have developed a new solution that is capable of powering smartphones for five continuous days or electric cars to run over 1,000 km without needing to refuel. The new […]



Researchers observe brain-like behavior in nanoscale device

December 30th, 2019 at 12:20 pm » Comments Off

A device like the one in the study (right), and an electron microscope image showing the device’s neuron-like arrangement of nanowires. UCLA scientists James Gimzewski and Adam Stieg are part of an international research team that has taken a significant stride toward the goal of creating thinking machines. Led by researchers at Japan’s National Institute […]



A nanotube material conducts heat in just one direction

December 21st, 2019 at 2:49 am » Comments Off

Photograph of nanotubes being created  Asymmetric conductors could revolutionize cooling systems for computers and other devices. Heat is something of a nuisance for electrical engineers. It reduces the reliability of electronic devices and even causes them to fail completely. That’s why computer components are liberally smeared with thermal paste and connected to heat pipes, fans, […]



Quantum states in conventional electronics may beat end of Moore’s law

December 15th, 2019 at 12:12 pm » Comments Off

Graduate students Kevin Miao, Chris Anderson, and Alexandre Bourassa monitor quantum experiments at the Pritzker School of Molecular Engineering Scientists at the University of Chicago’s Pritzker School of Molecular Engineering have found a way to produce quantum states in ordinary, everyday electronics. By harnessing the properties of quantum mechanics without exotic materials or equipment, this […]



SLAC scientists invent a way to see attosecond electron motions with an X-ray laser

December 13th, 2019 at 12:53 pm » Comments Off

Called XLEAP, the new method will provide sharp views of electrons in chemical processes that take place in billionths of a billionth of a second and drive crucial aspects of life. Menlo Park, Calif. — Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons […]



How the end of Moore’s Law will usher in a new era in computing

December 9th, 2019 at 11:50 am » Comments Off

Will the next evolution of technology super power our computers? In 1965 Gordon Moore, the founder of Intel, predicted that the number of components that could fit on a microchip would double every year for the next decade. Moore revised his prediction in 1975 to a doubling of components every two years – a prophecy […]



Why the world is running out of sand

November 25th, 2019 at 5:05 pm » Comments Off

It may be little more than grains of weathered rock, and can be found in deserts and on beaches around the world, but sand is also the world’s second most consumed natural resource. A South African entrepreneur shot dead in September. Two Indian villagers killed in a gun battle in August. A Mexican environmental activist […]



Multimaterial 3-D printing manufactures complex objects, fast

Multimaterial multinozzle 3D printheads. Credit: Nature (2019). DOI: 10.1038/s41586-019-1736-8 3-D printers are revolutionizing manufacturing by allowing users to create any physical shape they can imagine on-demand. However, most commercial printers are only able to build objects from a single material at a time and inkjet printers that are capable of multimaterial printing are constrained by […]



Scientists develop superfast-charging, high-capacity potassium batteries

November 19th, 2019 at 12:10 pm » Comments Off

Skoltech researchers in collaboration with scientists from the Institute for Problems of Chemical Physics of RAS and the Ural Federal University have shown that high-capacity, high-power batteries can be made from organic materials without lithium or other rare elements. In addition, they demonstrated the impressive stability of cathode materials and recorded high energy density in […]



Engineer finds way to pull diseases from blood using magnets

November 19th, 2019 at 12:06 pm » Comments Off

“IN THEORY, YOU CAN GO AFTER ALMOST ANYTHING. POISONS, PATHOGENS, VIRUSES, BACTERIA…” A British engineer has found a way to filter unwanted cells from blood using magnets — and his tool could be used in clinical trials as soon as next year. Thanks to existing research, biochemical scientist George Frodsham knew it was possible to […]



Porous polymer coatings dynamically control light and heat

November 10th, 2019 at 5:12 pm » Comments Off

The porous polymer coatings, which switch from white to transparent when wetted, can be put into plastic enclosures to make panels that control light and temperatures of buildings. Credit: Jyotirmoy Mandal/Columbia Engineering Buildings devote more than 30% of their energy use to heating, cooling, and lighting systems. Passive designs such as cool roof paints have […]
