Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons Researchers have demonstrated a novel concept for exciting and probing coherent phonons in crystals of a transiently broken symmetry. The key of this concept lies in reducing the symmetry of a crystal by appropriate optical excitation, as has been shown with the prototypical crystalline (...) [Science daily]  Self-driving cars lack social intelligence in traffic Self-driving cars fall short when it comes to understanding the social codes in traffic that let human drivers decide whether to give way or drive on, according to new research. [Science daily] Source-shifting metastructures composed of only one resin for location camouflaging Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer (...) [Science daily] Robot centipedes go for a walk Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic (...) [Science daily] Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips Engineers have developed a simple 3D-printed attachment that clips over a smartphone's camera and flash to measure blood pressure at the user's fingertip. The clip works with a custom smartphone app and currently costs about 80 cents to make. Researchers say it could help make regular (...) [Science daily] ChatGPT: US lawyer admits using AI for case research The lawyer told the judge he did not know content from the artificial intelligence could be false. [BBC News] ChatGPT: US lawyer admits using AI for case research The lawyer told the judge he did not know content from the artificial intelligence could be false. [BBC] Nanorobotic system presents new options for targeting fungal infections Researchers have developed a nanorobot system that targets fungal infections in the mouth. [Science daily] Effective as a collective: Researchers investigate the swarming behavior of microrobots Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted (...) [Science daily] Robots and Rights: Confucianism Offers Alternative As robots assume more roles in the world, a new analysis reviewed research on robot rights, concluding that granting rights to robots is a bad idea. Instead, the article looks to Confucianism to offer an alternative. [Science daily] Using AI, scientists find a drug that could combat drug-resistant infections Using AI, researchers identified a new antibiotic that can kill Acinetobacter baumannii, a type of bacteria that is responsible for many drug-resistant infections. [Science daily] Team develops new 'attacker' device to improve autonomous car safety Researchers have devised a novel algorithm to identify areas for improvement in autonomous vehicle security. [Science daily] Making the structure of 'fire ice' with nanoparticles Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations. [Science daily] Stretchable knee wearable offers insight into improving e-textiles for healthcare Researchers developed a fully knitted, circuit-embedded knee wearable for wireless sensing of joint motion in real-time. Compared to other knitted electronics, this model has fewer externally integrated components and a more sensitive sensor, making it less (...) [Science daily] The metaverse can lead to better science One researcher says we should look beyond the hype to see how virtual reality can make scientists more effective. But to realize the benefits, researchers must also plan well and avoid potential pitfalls. [Science daily]
