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.

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.

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.

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.

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.

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.

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.

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.

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.

An international team of researchers from biology, computer science and mathematics explains why evolution has a preference for symmetry.

Researchers aim to streamline the time- and resource-intensive process of screening ligands during catalyst design by using virtual ligands.
