A quantum computer has used a single atom to model the complex dynamics of organic molecules interacting with light
Researchers found that interoceptive awareness—the ability to sense internal bodily states—predicts whether people’s moral judgments match group norms. Brain scans revealed that resting-state activity in specific brain regions mediates this relationship.
A Korean research team has developed a light-powered artificial muscle that operates freely underwater, paving the way for next-generation soft robotics.
The research team—Dr. Hyun Kim at the Korea Research Institute of Chemical Technology (KRICT), Prof. Habeom Lee at Pusan National University, and Prof. Taylor H. Ware at Texas A&M University—successfully developed artificial muscles based on azobenzene-functionalized semicrystalline liquid crystal elastomers (AC-LCEs) that actuate in response to light.
The work has been published in the journal Small.
Scientists say they’ve put together a new kind of molecular toolkit that could eventually be used to treat a variety of brain diseases, possibly including epilepsy, sleep disorders and Huntington’s disease.
The kit currently contains more than 1,000 tools of a type known as enhancer AAV vectors, with AAV standing for “adeno-associated virus.” A consortium that included researchers from Seattle’s Allen Institute for Brain Science and the University of Washington combined harmless adeno-associated viruses with snippets of engineered DNA to create a gene-therapy package that could target specific neurons in the brain while having no effect on other cells.
Researchers laid out their findings in a set of eight studies published today in the Cell Press family of journals. The work is part of a project called the Armamentarium for Precision Brain Cell Access, funded through the National Institutes of Health’s BRAIN Initiative.
China is performing better in the artificial intelligence arms race than many Americans understand, according to the U.S.-China Economic and Security Review Commission’s Michael Kuiken.
OpenAI’s decision to buy Jony Ive’s gadget company, io, is about distribution.
Getting ChatGPT and other OpenAI models and products into the hands of users — that’s what really counts. Without that direct relationship, these products won’t be used as much, or it will cost a lot to get the offerings to consumers indirectly.
Sam Altman is working with Ive to secure direct user access, showing how distribution is becoming more important than technology in the AI race.

Ultra-processed foods now dominate the food supplies of high-income countries, with over 50% of energy intake coming from ultra-processed foods in the United States. Observational data has revealed that greater ultra-processed food consumption is associated with adverse mental health outcomes, while data from randomized controlled trials has demonstrated improvements to mental health following reduction in ultra-processed food intake. Ultra-processed foods are known to contain high concentrations of microplastics, largely due to both the processing and packing procedures. In light of recent findings which demonstrated alarming microplastic concentrations in the human brain, we propose that microplastics may partially mediate the adverse mental health effects of increasing ultra-processed food intake. In this viewpoint, we discuss the overlapping mechanisms for adverse mental health, paucity of research in the area, and propose a Dietary Microplastic Index (DMI) to study this potential relationship.
