Colorful asteroids near Neptune reveal a solar system conundrum | Scientific American

Planets and moons often get the spotlight, but there is much to learn about our solar system from its vast numbers of smaller bodies such as comets and asteroids. That is the mind-set of David Jewitt, a planetary scientist at the University of California, Los Angeles, who found a cosmic conundrum when he observed a group of asteroids near Neptune…. “The conundrum is that [Neptunian Trojans] don’t look the same as their source population, but there’s no obvious process by which their surfaces could be modified,” says Jewitt, who presented these results in October at the annual meeting of the American Astronomical Society’s Division for Planetary Sciences.

More than 20 California cities have unhealthy air quality from wildfires | CBS News

In the immediate aftermath, “We're much more likely to see emergency room visits and hospital admissions go up, and we are also likely to see increases in the mortality in the population,” Dr. Michael Jerrett, the chair of environmental health sciences at UCLA’s Fielding School of Public Health, told CBS News. “And then if it’s sustained over a long period of time, you know, months to years, you can begin to affect numerous major bodily systems that can lead to disease or premature death.”

It was just a nosebleed caused by bone-dry air — or was it? | Washington Post

Delayed diagnosis is the rule rather than the exception, said interventional radiologist Justin McWilliams, co-director of the HHT Center of Excellence at UCLA. On average, people with the disorder are diagnosed in their mid-30s. “HHT [hereditary hemorrhagic telangiectasia] is almost as common as cystic fibrosis,” a progressive genetic lung disease, said McWilliams, an associate professor of radiology at UCLA. “But unlike CF, most doctors have never heard of it and say to patients, ‘Oh, you have nosebleeds.’ Usually it’s kind of ignored.”

Why bigotry is a public health problem | The Conversation Opinion

Although correlation does not prove causation, clinical psychology professor Vickie M. Mays and colleagues at UCLA have hypothesized that the experience of race-based discrimination may set in motion a chain of physiological events, such as elevated blood pressure and heart rate, that eventually increase the risk of death. It’s unlikely that the adverse effects of discrimination and bigotry are limited to blacks and whites. For example, community health sciences professor Gilbert Gee and colleagues at UCLA have presented data showing that Asian-Americans who report discrimination are at elevated risk for poorer health, especially for mental health problems.

The diabetes symptom that finally helped Nick Jonas get a diagnosis | Self

Some people also experience blurred vision as an early symptom of type 1 diabetes. When your blood sugar levels are high, fluid in the tissue in the macula (a small area in the middle of your retina) of your eyes can leak — and that can cause blurry vision, Colin A. McCannel, M.D., professor of clinical ophthalmology and medical director of the UCLA Stein Eye Center in Santa Monica, Calif., tells Self.

Discovery of hotspots circling Milky Way black hole has astronomers excited | Space.com

Broderick’s work builds on earlier research by two teams that studied the galactic center of the Milky Way in near-infrared. This included the work of Reinhard Genzel, an astronomer from the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, as well as researchers Andrea Ghez and Mark Morris of University of California, Los Angeles. At the time, their work revealed that the center of the Milky Way wasn’t steady, but instead would drastically brighten about once a day for about 30 or 40 minutes, Broderick said. 

‘Demedicalization’ of mental illness often leaves homeless in the lurch | Medical Xpress

The article, by Drs. Joel Braslow and Luke Messac, argues that this case and countless others like it happen because many of the consequences of mental illness — including homelessness — have been “demedicalized,” or seen as falling outside the scope of medical care.… The article is part of a new series in New England Journal of Medicine called “Case Studies in Social Medicine,” which aims to bring social science perspectives into the medical field. Braslow is a professor of neuroscience history at the University of California, Los Angeles.

Astronomers discover giant relic of disrupted Tadpole galaxy | Phys.org

When galaxies are disrupted and disappear, their stars are either incorporated into more massive galaxies or are ejected into intergalactic space. “What makes this object extraordinary is that the tail alone is almost 500,000 light-years long,” says Professor R. Michael Rich of the University of California, Los Angeles. “If it were at the distance of the Andromeda galaxy, which is about 2.5 million light years from Earth, it would reach a fifth of the way to our own Milky Way.” (Also: Space Daily)
