Scientists know dark energy makes up about 70% of the universe and is responsible for the universe’s accelerating expansion. Beyond that, little about it is certain, so a West Virginia University engineer is enhancing the calibration of radio telescopes that can tell astronomers about dark energy by measuring the “neutral hydrogen” in the universe, a simple form of hydrogen with no net electric charge.

In addition to linguistic prompts, large language models can also understand, interpret, and adapt their responses to heart frequency data. Dr. Morris Gellisch, previously of Ruhr University Bochum, Germany, and now at University of Zurich, Switzerland, and Boris Burr from Ruhr University Bochum verified this in an experiment. They developed a technical interface through which the physiological data can be transmitted to the language model in real time. The AI can also account for subtle physiological signals such as changes in heart activity. This opens new doors for use in medical and care applications. The work was published in the technical magazine Frontiers in Digital Health on September 26, 2025.

Electrical engineers at Duke University have demonstrated the ability to print fully functional and recyclable electronics at sub-micrometer scales. The technique could impact the more than $150 billion electronic display industry and its environmental impact while providing a toehold for U.S. manufacturing to gain traction in a vital and quickly growing industry.

King Abdullah University of Science and Technology (KAUST; Saudi Arabia) researchers have set a record in microchip design, achieving the first six-stack hybrid CMOS (complementary metal-oxide semiconductor) for large-area electronics. With no other reported hybrid CMOS exceeding two stacks, the feat marks a new benchmark in integration density and efficiency, opening possibilities in electronic miniaturization and performance.

In a surprising discovery, MIT scientists found tiny loops in the genomes of dividing cells. Enabled by a high-resolution mapping technique, the findings overturn a long-held belief that the genome loses its 3D structure during mitosis.
