| Graphene key for novel hardware security Posted: 10 May 2021 02:19 PM PDT As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the encrypted keys harder to crack. |
| Light emitters for quantum circuits Posted: 10 May 2021 07:44 AM PDT The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers who developed integrated chips that can generate light particles on demand and without the need for extreme refrigeration. |
| This system helps robots better navigate emergency rooms Posted: 10 May 2021 07:43 AM PDT Computer scientists have developed a more accurate navigation system that will allow robots to better negotiate busy clinical environments in general and emergency departments more specifically. The researchers have also developed a dataset of open source videos to help train robotic navigation systems in the future. |
| Reaching your life goals as a single-celled organism Posted: 10 May 2021 07:43 AM PDT How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. A research team has now been able to simulate this process on the computer. |
| Universal equation for explosive phenomena Posted: 10 May 2021 07:43 AM PDT Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers have discovered a universal mathematical structure at these so-called tipping points. It creates the basis for a better understanding of the behavior of networked systems. |
| Intersection of 2D materials results in entirely New materials Posted: 10 May 2021 05:58 AM PDT Physics researchers discover that assembling 2D materials into a 3D arrangement does not just result in 'thicker' 2D materials but instead produces entirely new materials. The nanomesh technologically is simple to produce and offers tunable material properties to meet the demands of future applications. The team's next goal is to use the nanomesh on Silicon (Si) waveguides to develop quantum optical communications. |
| Smartphone breath alcohol testing devices vary widely in accuracy Posted: 09 May 2021 12:38 PM PDT The latest generation of personal alcohol breath testing devices pair with smartphones. While some of these devices were found to be relatively accurate, others may mislead users into thinking that they are fit to drive, according to a new study. |
| Open source tool can help identify gerrymandering in voting maps Posted: 06 May 2021 07:54 AM PDT Researchers describe the improved mathematical methodology of an open source tool called Gerrychain, which can help observers detect gerrymandering in a voting district plan by creating an ensemble of alternate maps that also meet legal voting criteria. |
