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 […]
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
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
Diamond quantum sensors can be used to analyze the magnetization response of soft magnetic materials used in power electronics; report scientists based on collaborative research. Using a novel imaging technique, they developed quantum protocols to simultaneously image both the amplitude and phase of AC stray fields over a wide frequency range up to 2.3 MHz.
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

Self-driving cars which eliminate traffic jams, getting a healthcare diagnosis instantly without leaving your home, or feeling the touch of loved ones based across the continent may sound like the stuff of science fiction. But new research, led by the University of Bristol and published today in the journal Nature Electronics, could make all this
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
Efficient and grounded models: Contributing to AI Mode in Search As LLMs grow larger and demand increases, our ability to improve model efficiency while maintaining and even elevating their quality determines our success in democratizing access to these high-performing models. Google Research has made breakthroughs in efficiency that have become industry standards, for example, our
Copper-chromium Prussian blue analogs are crystalline compounds containing voids (pores). The researchers found that the water retained in these pores can be expelled by applying pressure to these crystals. Previously reported onsite water production technologies rely on variations in temperature and humidity, and are thus strongly dependent on changes in environmental conditions, thereby often involving
