A dental floss that can measure stress

Chronic stress can lead to increased blood pressure and cardiovascular disease, decreased immune function, depression, and anxiety. Unfortunately, the tools we use to monitor stress are often imprecise or expensive, relying on self-reporting questionnaires and psychiatric evaluations. Now a Tufts interdisciplinary engineer and his team have devised a simple device using specially designed floss that

Fine-tuning LLMs with user-level differential privacy

Making these algorithms work for LLMs If we run these algorithms “out-of-the-box” for LLMs, things go badly. So, we came up with optimizations to the algorithms that fix the key issues with running them “out-of-the-box”. For ELS, we had to go from example-level DP guarantees to user-level DP guarantees. We found that previous work was

New biosensor solves old quantum riddle

Putting hypersensitive quantum sensors in a living cell is a promising path for tracking cell growth and diagnosing diseases — even cancers — in their early stages. Many of the best, most powerful quantum sensors can be created in small bits of diamond, but that leads to a separate issue: It’s hard to stick a

Efficiency upgrade for OLED screens: A route to blue PHOLED longevity

Blue phosphorescent OLEDs can now last as long as the green phosphorescent OLEDs already in devices, University of Michigan researchers have demonstrated, paving the way for further improving the energy efficiency of OLED screens. “This moves the blues into the domain of green lifetimes,” said Stephen Forrest, the Peter A. Franken Distinguished University Professor of

A rule-breaking, colorful silicone that could conduct electricity

A newly discovered silicone variant is a semiconductor, University of Michigan researchers have discovered — upending assumptions that the material class is exclusively insulating. “The material opens up the opportunity for new types of flat panel displays, flexible photovoltaics, wearable sensors or even clothing that can display different patterns or images,” said Richard Laine, U-M
