Working Towards Toxic-Free AI
Unlike existing work, which relies on training data from social media examples, a new benchmark, named ToxicChat, is based on examples gathered from real-world interactions between users and an AI-powered chatbot. ToxicChat is able to weed out queries that use seemingly harmless language but are actually harmful, which would pass muster with most current models.
Type 2 Diabetes Alters the Behavior of Discs in the Vertebral Column
Type 2 diabetes alters the behavior of discs in the vertebral column, making them stiffer, and also causes the discs to change shape earlier than normal.

A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation.
How Could a Piece of the Moon Become a Near-Earth Asteroid? Researchers Have an Answer
A team of astronomers has found a new clue that a recently discovered near-Earth asteroid, Kamo`oalewa, might be a chunk of the moon.
These Robots Helped Understand How Insects Evolved Two Distinct Strategies of Flight
Robots built by engineers at the University of California San Diego helped achieve a major breakthrough in understanding how insect flight evolved, described in the Oct. 4, 2023 issue of the journal Nature. The study is a result of a six-year long collaboration between roboticists at UC San Diego and biophysicists at the Georgia Institute of Technology.
New Technology Turns Smartphones into RFID Readers, Saving Costs and Reducing Waste
Imagine you can open your fridge, open an app on your phone and immediately know which items are expiring within a few days. This is one of the applications that a new technology developed by engineers at the University of California San Diego would enable.
This Groundbreaking Biomaterial Heals Tissues From the Inside Out
A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.
Scientists Use SDSC’s Expanse to Advance Green Chemistry
Computational chemists reduce or eliminate hazardous materials by running simulations to develop fast, accurate models. MIT researchers use SDSC’s supercomputer to explore the luminescent properties of iridium-centered phosphors.
Computer-generated Models Mimic Human Recognition at Supersonic Speed
Human cells are often a mixture of both abnormal and normal DNA – a mosaic, so to speak, and like the art form, this complex montage is difficult to understand. Neuroscience researchers are training computers to unveil new methods for DNA mosaic recognition.
New Web Tracking Technique is Bypassing Privacy Protections
Two years ago, several browsers that prioritize user privacy — including Safari, Firefox, and Brave — began to block third-party cookies for all users by default. Advertisers have responded by pioneering a new method for tracking users across the Web, known as user ID (or UID) smuggling, which does not require third-party cookies. But no one knew exactly how often this method was used to track people on the Internet.
Innovative Self-Powered Ingestible Sensor Opens New Avenues for Gut Research
Engineers developed a battery-free, pill-shaped ingestible biosensing system that gives scientists the ability to monitor gut metabolites in real time, which wasn’t possible before. The work could lead to a new understanding of intestinal metabolite composition, which significantly impacts human health.
Nanoengineers Develop a Predictive Database for Materials
Nanoengineers at the University of California San Diego’s Jacobs School of Engineering have developed an AI algorithm that predicts the structure and dynamic properties of any material—whether existing or new—almost instantaneously. Known as M3GNet, the algorithm was used to develop matterverse.ai, a database of more than 31 million yet-to-be-synthesized materials with properties predicted by machine learning algorithms. Matterverse.ai facilitates the discovery of new technological materials with exceptional properties.
The physics of walking is simpler than we thought
The physics of walking for multi-legged animals and robots is simpler than previously thought. That is the finding described by a team of roboticists, physicists and biologists in the Sept. 5 issue of the Proceedings of the National Academy of Sciences, in a paper titled “Walking is like slithering: a unifying, data-driven view of locomotion.”
A new neuromorphic chip for AI on the edge, at a small fraction of the energy and size of today’s compute platforms
An international team of researchers has designed and built a chip that runs computations directly in memory and can run a wide variety of AI applications–all at a fraction of the energy consumed by computing platforms for general-purpose AI computing. The NeuRRAM neuromorphic chip brings AI a step closer to running on a broad range of edge devices, disconnected from the cloud, where they can perform sophisticated cognitive tasks anywhere and anytime without relying on a network connection to a centralized server.
New $10M NSF-Funded Institute Will Get to the CORE of Data Science
A new National Science Foundation initiative has created a $10 million dollar institute led by computer and data scientists at University of California San DIego that aims to transform the core fundamentals of the rapidly emerging field of Data Science.
