| A new brain-computer interface with a flexible backing Posted: 15 Mar 2022 01:50 PM PDT Engineering researchers have invented an advanced brain-computer interface with a flexible and moldable backing and penetrating microneedles. Adding a flexible backing to this kind of brain-computer interface allows the device to more evenly conform to the brain's complex curved surface and to more uniformly distribute the microneedles that pierce the cortex. The microneedles, which are 10 times thinner than the human hair, protrude from the flexible backing, penetrate the surface of the brain tissue without piercing surface venules, and record signals from nearby nerve cells evenly across a wide area of the cortex. This novel brain-computer interface has thus far been tested in rodents. |
| Assessing the impact of automation on long-haul trucking Posted: 15 Mar 2022 09:14 AM PDT As automated truck technology continues to be developed in the United States, there are still many questions about how the technology will be deployed and what its potential impacts will be on the long-haul trucking market. |
| Optimizer tool designs, evaluates, maximizes solar-powered cooling systems Posted: 15 Mar 2022 08:29 AM PDT Researchers have developed an optimizer tool to design, evaluate, and maximize the performance of different types of solar-powered adsorption under various operating scenarios. The tool was created using Visual Basic programming language that is easy to learn and enables rapid application development and predicted the proper material mass concentration ratios. The method calculated the cooling load, predicted maximal performance, and conducted the overall performance analysis of the cooling system. |
| Hoverfly brains mapped to detect the sound of distant drones Posted: 15 Mar 2022 06:49 AM PDT Researchers have reverse engineered the visual systems of hoverflies to detect drones' acoustic signatures from almost four kilometers away. The finding could help combat the growing use of IED-carrying drones, including those used in Ukraine. |
| Are conferences worth the time and money? Posted: 14 Mar 2022 11:20 AM PDT Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual. |
| Warning: Objects in driverless car sensors may be closer than they appear Posted: 14 Mar 2022 11:20 AM PDT Researchers have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensor components into believing nearby objects are closer (or further) than they appear without being detected. The research suggests that adding optical 3D capabilities or the ability to share data with nearby cars may be necessary to fully protect autonomous cars from attacks. |
| Smartphone app calculates genetic risk for heart attack Posted: 14 Mar 2022 11:20 AM PDT Researchers have developed a smartphone app that can calculate users' genetic risk for coronary artery disease (CAD)--and found that users at high risk sought out appropriate medication after using the app. |
| Physicist shed light on the darkness Posted: 14 Mar 2022 09:07 AM PDT Experimental physicists have succeeded for the first time in controlling protected quantum states - so-called dark states - in superconducting quantum bits. The entangled states are 500 times more robust and could be used, for example, in quantum simulations. The method could also be used on other technological platforms. |
| Laser flashes for cancer research Posted: 14 Mar 2022 09:06 AM PDT Irradiation with fast protons is a more effective and less invasive cancer treatment than X-rays. However, modern proton therapy requires large particle accelerators, which has experts investigating alternative accelerator concepts, such as laser systems to accelerate protons. Such systems are deployed in preclinical studies to pave the way for optimal radiation therapy. A research team has now successfully tested irradiation with laser protons on animals. |
| Endless forms most beautiful: Why evolution favors symmetry Posted: 14 Mar 2022 06:57 AM PDT An international team of researchers from biology, computer science and mathematics explains why evolution has a preference for symmetry. |
| Chemical reaction design goes virtual Posted: 14 Mar 2022 06:57 AM PDT Researchers aim to streamline the time- and resource-intensive process of screening ligands during catalyst design by using virtual ligands. |
