Pompeii offers insights into ancient Roman building technology
2025-12-09
Concrete was the foundation of the ancient Roman empire. It enabled Rome’s storied architectural revolution as well as the construction of buildings, bridges, and aqueducts, many of which are still used some 2,000 years after their creation.
In 2023, MIT Associate Professor Admir Masic and his collaborators published a paper describing the manufacturing process that gave Roman concrete its longevity: Lime fragments were mixed with volcanic ash and other dry ingredients before the addition of water. Once water is added to this dry mix, heat is produced. As the concrete ...
University of Utah engineers give a bionic hand a mind of its own
2025-12-09
Whether you’re reaching for a mug, a pencil or someone’s hand, you don’t need to consciously instruct each of your fingers on where they need to go to get a proper grip.
The loss of that intrinsic ability is one of the many challenges people with prosthetic arms and hands face. Even with the most advanced robotic prostheses, these everyday activities come with an added cognitive burden as users purposefully open and close their fingers around a target.
Researchers at the University of Utah are now using artificial intelligence to solve this problem. By integrating proximity and pressure sensors into a commercial bionic hand, and then training ...
Transient and long-term risks of common physical activities in people with low back pain
2025-12-09

Residential solar panels can raise electricity rates
2025-12-09
A modeling study shows how under some conditions, increasing numbers of households with rooftop solar panels can lead to higher rates for those without their own solar system. When utility customers cancel their accounts after switching to residential solar panels, the utility must spread their fixed costs around to a smaller number of remaining customers, which can lead to rate increases. Charles Sims and colleagues studied how this pecuniary externality affects different income groups using agent-based computational economic modeling of the Tennessee Valley Authority (TVA), an area with some of the highest poverty rates in the United States. The authors asked 2,307 TVA residential customers ...
