by
Neuroscience News logo for mobile.

Resume: Researchers have developed a new approach to improve uncertainty estimates in machine learning models, increasing prediction accuracy. Their method, IF-COMP, uses the principle of minimum description length to provide more reliable confidence measures for AI decision-making, critical in high-stakes settings like healthcare. This scalable technique can be applied to large models, allowing non-experts to … Read more

MIT researchers introduce generative AI for databases

by

A new tool makes it easier for database users to perform complex statistical analyses on table data without having to know what’s happening behind the scenes. GenSQL, a generative AI system for databases, can help users make predictions, detect anomalies, guess missing values, fix errors, or generate synthetic data with just a few keystrokes. For … Read more

SciTechDaily

The surface of Titan. Simulations by MIT geologists indicate that the lakes and seas on Titan, Saturn’s largest moon, were formed by wave-induced erosion. Credit: NASA/JPL-Caltech Researchers find that wave activity on Saturn’s largest moon could be strong enough to erode the shorelines of lakes and seas. MIT researchers have used simulations to suggest that … Read more

How brains map memories without movement – Neuroscience News

by
Neuroscience News logo for mobile.

Resume: Mental maps in the brain are activated when thinking about sequences of experiences, even without physical movement. In an animal study, they found that the entorhinal cortex houses a cognitive map of experiences, which is activated during mental simulation. This is the first study to demonstrate the cellular basis of mental simulation in a … Read more

Light-activated muscles beat fatigue – Neuroscience News

by
Neuroscience News logo for mobile.

Resume: Researchers have developed a new approach to muscle control using light instead of electricity. This optogenetic technique provides more precise muscle control and significantly reduces fatigue in mice. Although not currently feasible in humans, this approach could revolutionize prosthetics and help people with reduced limb function. Key Facts: Optogenetic muscle stimulation provides more precise … Read more

MIT scientists learn how to control muscles with light

by

For people with paralysis or amputation, neuroprosthetic systems that artificially stimulate muscle contraction with electrical current can help them regain limb function. However, despite years of research, this type of prosthesis is not widely used because it leads to rapid muscle fatigue and poor control. MIT researchers have developed a new approach that they hope … Read more

Hidden in the Halo: MIT researchers discover the universe’s oldest stars

by
SciTechDaily

MIT astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are located in the Milky Way’s “halo” – the cloud of stars surrounding the main galactic disk – and they appear to have formed between 12 and 13 billion years ago, when the very … Read more
