Campus Queries is a series in which Daily Bruin readers and staff present science-related questions for UCLA professors and experts to answer. Q: What is the best way to preserve eyesight? A: Aside from getting glasses or going through laser eye surgery, there is little people can do to slow the rate of eyesight degradation, […]

Team led by UCLA astronomers discovers new method of estimating Hubble constant
UCLA researchers helped develop a new technique to improve the precision of the Hubble constant estimation, which is key in figuring out how quickly the universe is expanding. The UCLA astronomers estimated the constant to be 72.5 kilometers per second per megaparsec in their study published Jan. 22. Previous estimates ranged from 67 to 73 […]
Popularity of brief Uber, Lyft rides on campus raises environmental concerns
This post was updated Feb. 1 at 1:27 p.m. UCLA students call about 11,000 Uber and Lyft rides that never leave campus every week, raising concerns about the environmental impact of unnecessary trips. UCLA Transportation determined this number using data provided by the two ride-hail companies, said Abdallah Daboussi, senior administrative planning and policy analyst […]
Limitations, mosaic nature of global health tackled at LA Global Health Conference
An anthropologist said everyone should care about global health at an on-campus event Saturday. This year’s Los Angeles Global Health Conference focused on the future of global health. Speakers at the conference presented on topics ranging from food access in Native American communities to surgical care in other countries. Carolyn Smullin and Samuel Lewis, medical […]
UCLA researchers discover new limits of machine learning
UCLA researchers found the limits of deep learning networks – distinguishing between an otter and a can opener. Nicholas Baker, a cognitive psychology graduate student, explored the behaviors of two machine learning networks known as convolutional neural networks, which are well-established machine learning networks capable of visual recognition. The study aimed to test whether the […]
Women-only ride-hailing services not on the map for the future, report says
A UCLA researcher said women-only ride-hailing services may make ride-hailing safer for women, but may not be economically feasible. Christopher Tang, a distinguished professor at the UCLA Anderson School of Management, co-authored a report this month discussing the political and economic concerns associated with women-only ride-hailing services. The report came in the wake of several […]
Development of haptic sensors allows for physical feedback in robotic surgery
UCLA engineers developed a novel sensor that could add a sense of “touch” to robotic surgery. Robert Candler, an associate professor of electrical engineering, helped develop a haptic feedback sensor that, when placed on the tips of surgical instruments, would provide feedback on the various forces exerted on body tissues to better guide surgery. In […]
