The finding represents one of the clearest examples to date of the phenomenon — stretches of DNA that exist for no reason other than promoting their own inheritance — at the molecular level.

In bright light, mammals rapidly recycle spent pigments via a process that ensures photoreceptors retain levels of light-sensitive pigments sufficient for uninterrupted sight.

Chef Massimo Bottura, whose Osteria Francescana is among the world’s most highly regarded restaurants, will appear at the fifth annual public lecture.

Studying the animals’ bones, UCLA biologists found injuries to shoulders and backs after likely attacks on large prey.

UCLA Ph.D. student Andy Tay writes about a crucial a challenge to long-distance space travel — overcoming the long-term effects of microgravity on our bodies.

UCLA's Congo Basin Institute led a team of UCLA and Cameroonian students into a rain forest in central Africa to reopen a field station in a jungle with a thriving ecosystem with birds, elephants and monkeys.

UCLA biologists are exploring ways to defeat antibiotic-resistant bacteria; a mathematical formula they created can help predict which combinations of drugs will be most effective.

For UCLA biologist Daniel Blumstein celebrating the lowly marmot could shed light on global warming.

You can be among the 1,000 volunteer citizen scientists who will collect 18,000 samples of soil and aquatic sediment from across the state through a new University of California program called CALeDNA.

The UCLA Sustainable LA Grand Challenge awarded its second round competitive research grants this month, providing $1 million to eight new projects focusing on renewable energy, transportation and urban ecosystems.

To turn on its genome — the full set of genes inherited from each parent — a mammalian embryo needs to relocate a group of proteins, researchers have discovered. The metabolic proteins move to the DNA-containing nuclei about two days after a mouse embryo is fertilized, according to the study.

Almost half of the fish ordered at Los Angeles-area sushi restaurants turned out to be mislabeled, which has both environmental and public health implications.

Two UCLA faculty members — molecular biologist Robert Goldberg and international law and policy scholar Edward Parson — defended the use of genetically modified organisms in food production at a Zócalo/UCLA discussion held in downtown Los Angeles.

UCLA scientists have found that calcification of heart muscle tissue is caused when a type of cell called cardiac fibroblasts go awry.

Study finds that ‘childhood imprinting’ limits people’s susceptibility to severe infection from two major strains of avian influenza.

The discoveries led by UCLA researchers may lead to major insights about light perception and how circadian clocks could affect human health.

Students in “Intro to Oceanography” spoof music videos for the sake of science.

From the capuchin monkeys of Costa Rica to the Los Angeles area's mountain lions, UCLA experts are developing new techniques and advancing knowledge.

Twenty-eight outstanding undergraduates from across the country are spending eight weeks at UCLA, learning the latest data analysis techniques and skills that are transforming the biosciences.

UCLA biologists have found genetic evidence that supports keeping the gray wolf protected by the U.S. Fish and Wildlife Service, which might rule this fall to remove it from the endangered list.

The finding could help reduce the number of deaths from drug-resistant infections — currently about 700,000 each year.

Led by Steven Clarke, Distinguished Professor of Chemistry and Biochemistry, the program prepares the next generation of doctoral students for successful careers in the biosciences.
