Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The plastic can't be broken down by biotechnological means, either. Researchers are looking for ways to rectify this: An international team decoded a bacterial enzyme that plays a key role in styrene degradation. This paves the way for biotechnological application.

Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.

Actually, sometimes consumers don't want to talk to a real person when they're shopping online, a new study suggests. In fact, what they really want is a chatbot that makes it clear that it is not human at all. In a new study, researchers found that people preferred interacting with chatbots when they felt embarrassed about what they were buying online -- items like antidiarrheal medicine or, for some people, skin care products.

A method has been discovered to treat water heavily contaminated with unhealthful forever chemicals, known by chemists as PFAS or poly- and per-fluoroalkyl substances. It involves treating heavily contaminated water with ultraviolet (UV) light, sulfite, and a process called electrochemical oxidation. It breaks up strong fluorine-to-carbon bonds in the PFAS compounds and other concentrated organic compounds in heavily polluted water. The reaction also occurs at room temperature without a need for additional heat or high pressure. This method is expected to be useful in cleanups of PFAS pollution from decades of fire suppressant foam use at military facilities.

Perovskites are among the most researched topics in materials science. Recently, a research team has solved an age-old challenge to synthesize all-organic two-dimensional perovskites, extending the field into the exciting realm of 2D materials. This breakthrough opens up a new field of 2D all-organic perovskites, which holds promise for both fundamental science and potential applications.

Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.

Conversational agents (CAs) such as Alexa and Siri are designed to answer questions, offer suggestions -- and even display empathy. However, new research finds they do poorly compared to humans when interpreting and exploring a user's experience.

What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged.

Move over, graphene. There's a new, improved two-dimensional material in the lab. Borophene, the atomically thin version of boron first synthesized in 2015, is more conductive, thinner, lighter, stronger and more flexible than graphene, the 2D version of carbon. Now, researchers have made the material potentially more useful by imparting chirality -- or handedness -- on it, which could make for advanced sensors and implantable medical devices.
