A team of UCLA researchers has created the most powerful high-performance nanoscale microwave oscillators in the world, a development that could lead to cheaper, more energy-efficient mobile communication devices that deliver much better signal quality. Today's cell phones, WiFi—enabled tablets and other electronic gadgets all use microwave oscillators, tiny devices that generate the electrical signals used in communications. In a cell phone, for example, the transmitter and receiver...

A mathematical model that has been used for more than 80 years to determine the hunting range of animals in the wild holds promise for mapping the territories of street gangs, a UCLA-led team of social scientists reports in a new study. "The way gangs break up their neighborhoods into unique territories is a lot like the way lions or honey bees break up space," said lead author P. Jeffrey Brantingham, a professor of anthropology at UCLA. Further, the research demonstrates that the most...

Five Degree Temperature Increases Expected In Southern California By Mid-Century

Climate change could have a profound impact on Southern California, as the region could be several degrees warmer by the middle of the century, according to a new UCLA study released on Thursday. The southern part of the state could be three to five degrees warmer in the years 2041 to 2060, though differences between the coast and inland locations and mountainous and desert areas will mean that the heat increase will vary, the Associated Press (AP) reported on Thursday. The study, which...

(Ivanhoe Newswire) -- Approximately three out of every 1,000 people in the United States suffer from some degree of Autism. Now, a new study is looking at why this happens by studying your genes. Researchers at UCLA are conducting a study to explain why one person has an ASD (autism spectrum disorder) and another does not. The study pinpoints ASD risk factors by comparing changes in gene expression with DNA mutation data in the same individuals. ASDs are a heterogeneous group of...

Findings could lead to future therapeutic targets UCLA researchers have combined two tools — gene expression and the use of peripheral blood -- to expand scientists' arsenal of methods for pinpointing genes that play a role in autism. Published in the June 21 online edition of the American Journal of Human Genetics, the findings could help scientists zero in on genes that offer future therapeutic targets for the disorder. "Technological advances now allow us to rapidly sequence...

UCLA biochemists have mapped the structure of a key protein—RNA complex that is required for the assembly of telomerase, an enzyme important in both cancer and aging. The researchers found that a region at the end of the p65 protein that includes a flexible tail is responsible for bending telomerase's RNA backbone in order to create a scaffold for the assembly of other protein building blocks. Understanding this protein, which is found in a type of single-celled organism that lives...

Unique UCLA program that teaches social skills proves effective over long term Teenagers with autism spectrum disorder are in a bind. The disorder is characterized by impairments in communication and social interaction, but it's a continuum, so some teens diagnosed with ASD are considered high functioning and healthy enough to be "mainstreamed" in school. But without the proper social skills, even mainstreamed teens don't quite fit into the general social milieu of middle school or high...

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...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
