Professor emeritus Bruce Runnegar was part of the team that got to the bottom of the situation.
The visionary leader served the campus as vice chancellor of medical sciences and dean of the David Geffen School of Medicine at UCLA from 1994 to 2010.
Sifting through studies on various species’ play behavior, researchers tracked vocalization patterns that show a strong similarity to human laughter.
A new study reveals new findings about the animals’ evolution and the tough prospects they face for survival.
The first study to report genome-wide data on the prehistoric canid puts to bed a mystery biologists have pondered for more than 100 years.
Birthrates, marriage, gender roles will change dramatically in post-pandemic world, scientists predict
The longer COVID-19 continues, the more entrenched these psychological, social and societal changes are likely to be, the study authors suggest.
In very early life, sleep helps build the brain’s infrastructure, but it then takes on an entirely new decluttering role, research shows.
Two UCLA studies of ocean mollusks shed light on how new species may emerge through a phenomenon known as host-switching.
UCLA’s Daniel Fessler explains why staying away from each other seems so tough, even when we know it will save lives.
The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction.
“Today’s rich biodiversity among marine fish shows the fingerprints of the mass extinction at the end of the Cretaceous period,” said Michael Alfaro, a professor of ecology and evolutionary biology.
The study, by UCLA and the University of Wisconsin, was based on analysis of specimens more than 3 billion years old.
UCLA research shows that the changes have had a dramatic effect on Colpichthys hubbsi, a species that lives only in the region near the Sea of Cortez.
UCLA research findings show changes in same genes that clipped the sea bird’s wings cause human bone disorders.
Studying the animals’ bones, UCLA biologists found injuries to shoulders and backs after likely attacks on large prey.
The Norman Sprague Professor of Biological Chemistry at the School of Medicine gives the UCLA Faculty Research Lecture on Oct. 13.
UCLA biologists write that the findings should help guide how endangered species are treated.
Denisovans, ancient hominids who lived alongside humans and Neanderthals, were first described in 2010 through DNA extracted from remains in a Siberian cave in 2008.
The animals, which are related to spiders and scorpions, “look terrifying, but are actually delicate, timid and afraid of you,” says UCLA doctoral candidate Kenneth Chapin.
These changes could potentially lead to various developmental disorders and other health risks.
Archaeologist Matthew Curtis was part of a team that recently discovered a skeleton that yielded the first complete ancient genome ever found in Africa.
Life scientists from UCLA and other universities in the U.S. and England argue that predatory animals helped keep the population of large herbivores in check.
The presence of humans changes the way animals behave, and those changes may make them more vulnerable.
UCLA biologists have found that male aggression against potential rivals for females explains much of the phenomenon.
Darwin’s writings focused much more on species that had changed over time than on those that hadn’t. So how do scientists explain a species living for so long without evolving?
