Although humans and woolly mammoths co-existed for millennia, the shaggy giants disappeared from the globe between 4,000 and 10,000 years ago, and scientists couldn't explain until recently exactly how the Flinstonian behemoths went extinct. In a paper published June 12 in the journal Nature Communications, UCLA researchers and colleagues reveal that not long after the last ice age, the last woolly mammoths succumbed to a lethal combination of climate warming, encroaching humans and...

Discovery of mutation ends UCLA doctor's 20-year quest The Caterpillar got down off the mushroom and crawled away in the grass, remarking as it went, 'One side will make you grow taller, and the other side will make you grow shorter.' -Alice's Adventures in Wonderland, by Lewis Carroll UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann...

UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict the climates of the past using the fossil record. The research, published May 15 in the journal Nature Communications, has a range of fundamental implications for global ecology and allows researchers to estimate original leaf sizes from just a fragment of a leaf. This will improve scientists'...

A large survey of human genetic variation, published today in the online version of the journal Science, shows that rare genetic variants are not so rare after all and offers insights into human diseases. "I knew there would be rare variation but had no idea there would be so much of it," said the senior author of the research, John Novembre, an assistant professor of ecology and evolutionary biology and of bioinformatics at UCLA. A team of life scientists studied 202 genes in 14,002...

UCLA researchers may have found a key to determining which Parkinson's disease patients will experience a more rapid decline in motor function, sparking hopes for the development of new therapies and helping identify those who could benefit most from early intervention. In a study published May 15 in the peer-reviewed online journal PLoS ONE, the researchers found that Parkinson's sufferers who possess two specific variants of a gene known to be a risk factor for the disease had a...

Can Too Much Sugar Make You Stupid?

Dentists have long warned that too much sugar can rot a person's teeth, but scientists at UCLA have discovered evidence that too much soda and candy could also rot a person's brain. The study, which was published Tuesday in the Journal of Physiology, discovered how a diet that is "steadily high" in fructose can slow down the function of the brain, impairing memory and learning ability, the Los Angeles-based university said in a May 15 press release. Those adverse effects, they say, can...
