A research team from the Department of Energy’s Oak Ridge National Laboratory, in collaboration with North Carolina State University, has developed a simulation capable of predicting how tens of thousands of electrons move in materials in real time, or natural time rather than compute time.

The project reflects a longstanding partnership between ORNL and NCSU, combining ORNL’s expertise in time-dependent quantum methods with NCSU’s advanced quantum simulation platform developed under the leadership of Professor Jerry Bernholc.

Using the Oak Ridge Leadership Computing Facility’s Frontier supercomputer, the world’s first to break the exascale barrier, the research team developed a real-time, time-dependent density functional theory, or RT-TDDFT, capability within the open-source Real-space Multigrid, or RMG, code to model systems of up to 24,000 electrons.

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.

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.
