How Do Fruit Flies Detect Sweet Foods?
2014-01-14 10:01:27

University of California - Riverside UC Riverside research opens door for investigations into taste receptors of mosquitoes and other deadly insects Insects represent remarkable diversity and have adapted to all sorts of ecological nooks and crannies. For example, they have taste receptors — novel proteins — with which they taste chemicals and make important choices about not only foods but also mates and where to deposit their eggs. These receptors are widely seen as being at the...

Researchers Discover How Calcium Phosphate Can Make Stem Cells Become Bone-building Cells
2014-01-07 08:10:29

University of California, San Diego With the help of biomimetic matrices, a research team led by bioengineers at the University of California, San Diego has discovered exactly how calcium phosphate can coax stem cells to become bone-building cells. This work is published in the Proceedings of the National Academy of Sciences the week of Jan. 6, 2014. UC San Diego Jacobs School of Engineering professor Shyni Varghese and colleagues have traced a surprising pathway from these biomaterials...

Interactive Maps Of US Metro Areas Shows Striking Differences Between Cities And Suburbs

University of California - Berkeley According to a new study by researchers at the University of California, Berkeley, population-dense cities contribute less greenhouse gas emissions per person than other areas of the country, but these cities' extensive suburbs essentially wipe out the climate benefits. Dominated by emissions from cars, trucks and other forms of transportation, suburbs account for about 50 percent of all household emissions – largely carbon dioxide – in United...

Novel Attract-and-kill Approach Developed To Target Argentine Ants
2014-01-06 13:15:08

University of California - Riverside UC Riverside entomologists devise a technique that involves mixing a synthetic pheromone in insecticide sprays After being inadvertently introduced in the United States from South America, Argentine ants have successfully invaded urban, agricultural, and natural settings nationwide. In urban California, the Argentine ant is among the primary pest ants. For example, this particular species of ants makes up 85 percent of ants sampled by commercial pest...

wrist mri

redOrbit Staff & Wire Reports - Your Universe Online Researchers have developed a new method of diagnosing wrist problems by creating “movies” of the radiocarpal joint in motion using a series of brief magnetic resonance imaging (MRI) scans, according to a study appearing in Tuesday’s edition of PLoS ONE. The process is known as Active MRI, and according to the study authors, it could be used to diagnose subtle changes in physiology indicative of the onset of conditions such...

With no place to puff, smokers are more likely to cut back or quit, researchers say Completely banning tobacco use inside the home – or more broadly in the whole city – measurably boosts the odds of smokers either cutting back or quitting entirely, report University of California, San Diego School of Medicine researchers in the current online issue of Preventive Medicine. "When there's a total smoking ban in the home, we found that smokers are more likely to reduce tobacco...

Diamonds In Earth's Oldest Zircons Are Fragments Of Polishing Compound
2013-12-19 07:44:15

University of California - Riverside As is well known, the Earth is about 4.6 billion years old. No rocks exist, however, that are older than about 3.8 billion years. A sedimentary rock section in the Jack Hills of western Australia, more than 3 billion years old, contains within it zircons that were eroded from rocks as old as about 4.3 billion years, making these zircons, called Jack Hills zircons, the oldest recorded geological material on the planet. In 2007 and 2008, two research...

Decades-old Mystery In Earth's Upper Atmosphere Solved
2013-12-18 14:51:49

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...
