AI paired with tiny optical device corrects distorted light for sharper imaging
AI paired with tiny optical device corrects distorted light for sharper imaging Gaby Clark Scientific Editor Robert Egan Associate Editor Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a tiny yet carefully engineered optical element and artificial intelligence, University of California San Diego engineers have built a way to spot and correct those distortions from a single image—a step that could make advanced optical...
Popular weight-loss diet shows surprising impact on serious mental health condition
The keto diet may help individuals with anorexia nervosa, new research from UC San Diego School of Medicine suggests. The small study, published in the journal Nature, enrolled 22 women between 18 and 45 years old who had a history of anorexia nervosa and a BMI (body mass index) above 17.5.Anorexia nervosa (AN) is a severe psychiatric disorder involving food restriction and low body weight, the researchers describe. This is often followed by body dissatisfaction, an intense fear of eating,...
Q&A: Experts discuss rise of profanity from politicians
In American politics, cursing and "four-letter words" are no longer confined to hot mics or hidden behind closed doors. Politicians and pundits are increasingly using so-called "bad words" in speeches, social media posts and campaign ads. Benjamin Bergen, professor of cognitive science, and Pamela Ban, associate professor of political science, both from UC San Diego's School of Social Sciences, examine why swearing among politicians is on the rise and what it reveals about persuasion,...
New drug could finally stop deadly fatty liver disease
Scientists at UC San Diego have unveiled a potentially game-changing treatment for MASH, a severe fatty liver disease affecting millions worldwide. The experimental drug, ION224, blocks a liver enzyme that drives fat buildup and inflammation, two key forces behind liver damage. In clinical trials, patients showed striking improvements in liver health, even without losing weight.
Plants could be used to grow medicines in space, study shows
Plants could be used to grow medicines in space, study shows Lisa Lock Scientific Editor Robert Egan Associate Editor Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste. The...
Actually, the SAT Was Necessary After All
Zvezdelina Stankova has taught mathematics at UC Berkeley for nearly three decades. But in 2023, while teaching introductory calculus for the first time since the beginning of the coronavirus pandemic, she noticed that something was quite wrong. The bottom 25 percent of students were not just struggling with the coursework, Stankova told me; “people were in freefall.”
California professor argues need for 'objective measures' after state drops ACT/SAT requirement
A growing consortium of University of California professors is urging the state university system to bring back standardized testing, warning that the elimination of admissions tests has degraded academic readiness and forced instructors to teach "middle school math" to college undergraduates. More than 1,400 UC faculty members have signed an open letter calling on leadership to reinstate the SAT and ACT mathematics requirements for Science, Technology, Engineering, and Math (STEM) majors....
California's tectonic stress has reached record level, earthquake model reveals
California's tectonic stress has reached record level, earthquake model reveals Gaby Clark Scientific Editor Robert Egan Associate Editor Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and become locked. Stress builds up over long periods and is suddenly released in the form of an earthquake. In Southern California, the San Andreas and San Jacinto faults are among the most significant of these zones, accommodating most of...
Nvidia picks Unitree for humanoid robot platform as Chinese startup eyes IPO
Nvidia has selected Chinese humanoid robot maker Unitree for the first robotics system the U.S. chipmaker is selling to researchers from Stanford to ETH Zurich, the company announced Monday. The system combines Unitree's nearly 6-foot-tall H2 humanoid robot with Nvidia's Jetson Thor hardware, which includes the company's advanced Blackwell GPU for on-device artificial intelligence capabilities. Nvidia's humanoid-focused AI models, known as Isaac GR00T, and simulation systems are part of the...
NVIDIA's Isaac Gr00t platform gives researchers access to frontier humanoid robotics
NVIDIA's Isaac Gr00t platform gives researchers access to frontier humanoid robotics It uses a nearly 6-foot tall humanoid chassis and tactile five finger hands. As part of his AI-palooza Computex keynote, NVIDIA's Jensen Huang dove into the most relatable form of artificial intelligence: robots. The company announced the new Isaac Gr00t reference design humanoid robot platform that combines a Unitree H2 Plus humanoid robot, Sharpa five-fingered hands and NVIDIA Jetson Thor onboard compute.
