| Blockchain technology could provide secure communications for robot teams Posted: 05 Oct 2021 02:54 PM PDT The use of blockchain technology as a communication tool for a team of robots could provide security and safeguard against deception, according to a new study. The research may also have applications in cities where multirobot systems of self-driving cars are delivering goods and moving people across town. |
| Smuggling light through opaque materials Posted: 05 Oct 2021 09:47 AM PDT Electrical engineers have discovered that changing the physical shape of a class of materials commonly used in electronics can extend their use into the visible and ultraviolet parts of the electromagnetic spectrum. Already commercially used in detectors, lenses and optical fibers, chalcogenide glasses may now find a home in applications such as underwater communications, environmental monitoring and biological imaging. |
| Posted: 05 Oct 2021 09:47 AM PDT Researchers developed a fully-integrated robotic arm that fuses visual data from a camera and radio frequency (RF) information from an antenna to find and retrieve object, even when they are buried under a pile and fully out of view. |
| Ultra-short flashes of light illuminate a possible path to future beyond-CMOS electronics Posted: 05 Oct 2021 07:19 AM PDT Researchers have demonstrated that ultra-short pulses of light, down to 34 millionths of a billionth of a second, elicit the same response as continuous illumination. The experiment harnessed interactions between real and virtual states to 'switch' the electronic state of an atomically-thin (2D) material, tungsten-disulfide, aiding the search for future low-energy electronics based on exotic topological materials. |
| Income inequality can harm children’s achievement in maths – but not reading, 27-year study suggests Posted: 05 Oct 2021 07:19 AM PDT Inequalities in income affect how well children do in maths -- but not reading, the most comprehensive study of its kind has found. |
