Solar mini-reactors The University of Amsterdam has developed a standalone solar-powered mini-reactor. The technology could one day serve as an autonomous off-grid photochemistry system for remote locations. The prototype solar reactor measures 0.25 square meters. The system is equipped with a solar cell, which provides the power for the pumps and control system. This solar cell is placed ... » read more

Cybersecurity Check Point Software Technologies reports that facsimile machines (yes, people still use them!) can be subject to hacking through vulnerabilities in their communication protocols. The HP Officejet Pro All-in-One fax printers and other fax machines can be compromised with a hacker only knowing a fax number, according to the company. Check Point Research says a design flaw in Andro... » read more

Low power Wi-Fi Computer scientists and electrical engineers from the University of Washington came up with a way to generate Wi-Fi transmissions using 10,000 times less power than conventional methods and which consumes 1,000 times less power than existing energy-efficient wireless communication platforms such as Bluetooth Low Energy and Zigbee. The system, Passive Wi-Fi, uses backscatte... » read more

New switchable material Two MIT researchers developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its new configuration until switched back by another voltage. The discovery could pave the way for a new kind of nonvolatile memory. The findings involve the thin-... » read more

Incandescent bulbs might not be dead yet Can incandescent bulbs be as efficient – or even more so – than LEDs? More than 95 percent of the energy that goes into incandescents is wasted, most of it as heat, so researchers at MIT and Purdue University struck out to see if that could be changed. A conventional heated metal filament, with all its attendant losses, served as the basis. But... » read more
