UC Riverside-led team identifies black carbon and tropospheric ozone as most likely drivers of large-scale atmospheric circulation change in the Northern hemisphere tropics Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows. While stratospheric ozone depletion has...

'Fusarium dieback' severely damaged avocados in Israel, says UC Riverside plant pathologist Akif Eskalen, who identified the fungus A plant pathologist at the University of California, Riverside has identified a fungus that has been linked to the branch dieback and general decline of several backyard avocado and landscape trees in residential neighborhoods of Los Angeles County. The fungus is a new species of Fusarium . Scientists are working on characterizing its specific...

Selenium Impacts Honey Bee Behavior And Survival

UC Riverside entomologists develop 'proof of concept' that selenium may negatively impact honey bee populations at selenium-polluted sites Entomologists at the University of California, Riverside have a "proof of concept" that selenium, a nonmetal chemical element, can disrupt the foraging behavior and survival of honey bees. Selenium in very low concentrations is necessary for the normal development of insects – and humans – but becomes toxic at only slightly higher...

Image 1 - Paleontologists Discover Oldest Organism With A Skeleton
2012-03-10 05:50:09

Paleontologists have discovered the oldest organism with a skeleton in Australia. The creature is called Coronacollina acula and is estimated to be between 550 and 560 million years old. Paleontologists estimate this animal is from the Ediacaran Period, before the diversification of organisms in the Cambrian Period. The study results appeared online February 14 in Geology. This important find could be the key to unlocking several questions about early life, evolution, and extinction....

A UC Riverside Ph.D. candidate finds that ethnic media focus on public opinion and issues influences state legislators of every ethnicity. Spanish-language media in the United States play a critical role in shaping perceptions of public opinion among Latino voters and public officials of every ethnicity across the country. They also play a far greater advocacy role for the communities they serve than do their English-language counterparts, according to a University of California, Riverside...

UC Riverside and CSU Northridge sociologists´ research suggests how bankers, stock brokers and mortgage lenders justified ruinous actions. Why do some people behave morally while others do not? Sociologists at the University of California, Riverside and California State University, Northridge have developed a theory of the moral self that may help explain the ethical lapses in the banking, investment and mortgage-lending industries that nearly ruined the U.S. economy. For decades,...

Image 1 - California Researchers Hoping To Reveal Secrets of Anti-Gravity
2012-01-30 05:16:30

A team of researchers from the University of California, Riverside (UCR) say they are close to determining whether or not anti-matter exerts a sort of "anti-gravity" in much the same what that ordinary matter exerts regular gravity. In an article published Friday, BBC News reports that, while it is well known that normal matter attracts all other matter in the universe, scientists currently do not know if anti-matter would attract other matter, or repel it. A trio of UCR experts may...

Rarest Bumblebee in US Discovered In New Mexico
2011-12-06 13:13:20

Researchers from University of California Riverside (UCR), have recently rediscovered one of the rarest species of bumblebee in the United States - one that has not been seen in over 50 years. The Cockerell´s Bumblebee was found in the White Mountains of south-central New Mexico this last summer. Douglas Yanega, senior museum scientist at UC Riverside explains the rarity of this find, "Most bumblebees in the US are known from dozens to thousands of specimens, but not this species."...

Researchers Study Flight Patterns Of Mosquitoes
2011-10-01 07:27:04

Experiments by University of California Riverside entomologists demonstrate mosquitoes are attracted first to carbon dioxide, then to skin odors; findings could lead to more effective mosquito traps The carbon dioxide we exhale and the odors our skins emanate serve as crucial cues to female mosquitoes on the hunt for human hosts to bite and spread diseases such as malaria, dengue and yellow fever. Two entomologists at the University of California, Riverside have now performed...

Fortuitous discovery in UC Riverside physics lab made using stacked layers of “wonder material” An accidental discovery in a physicist´s laboratory at the University of California, Riverside provides a unique route for tuning the electrical properties of graphene, nature´s thinnest elastic material. This route holds great promise for replacing silicon with graphene in the microchip industry. The researchers found that stacking up three layers of graphene, like...
