UA undergraduate researcher Robert Clark, his public health mentor and Pima County officials collaborated on an investigation of rabies cases in Pima County.
In a volunteer opportunity turned research project, University of Arizona undergraduate researcher Robert Clark has developed a comprehensive, multi-year snapshot of animal cases of rabies in Pima County.
Clark began working with a mentor in the UA Mel and Enid Zuckerman College of Public Health and county officials to learn about the seasonality of rabies in animals and identify exactly where rabid animals were most often found. (more…)
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate.
The idea of recreating dinosaurs by extracting DNA from insects in amber has held the fascination of the public for two decades. Claims for successful extraction of DNA from ambers up to 130 million-years-old by various scientists in the early 1990s were only seriously questioned when a study at the Natural History Museum, London, was unable to replicate the process. The original claims are now considered by many to be a text-book example of modern contaminant DNA in the samples. Nonetheless, some scientists hold fast to their original claims.
Research just published in the journal The Public Library of Science ONE (PLOS ONE) by a team of researchers from the Faculty of Life Sciences at The University of Manchester can now confirm that the existence of DNA in amber fossils is highly unlikely. The team led by amber expert Dr David Penney and co-ordinated by ancient DNA expert Professor Terry Brown used highly-sensitive ‘next generation’ sequencing techniques – the most advance type of DNA sequencing – on insects in copal, the sub-fossilized resin precursor of amber.

Berkeley Lab Researchers at Joint Center for Artificial Photosynthesis Make Unique Semiconductor/Catalyst Construct
In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic leaves that could produce energy-dense fuels from nothing more than sunlight, water and atmosphere-warming carbon dioxide, with no byproducts other than oxygen, represent an ideal alternative to fossil fuels but also pose numerous scientific challenges. A major step toward meeting at least one of these challenges has been achieved by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) working at the Joint Center for Artificial Photosynthesis (JCAP).
“We’ve developed a method by which molecular hydrogen-producing catalysts can be interfaced with a semiconductor that absorbs visible light,” says Gary Moore, a chemist with Berkeley Lab’s Physical Biosciences Division and principal investigator for JCAP. “Our experimental results indicate that the catalyst and the light-absorber are interfaced structurally as well as functionally.” (more…)
Man has two basic requirements – food and the sexual gratification. In order to enjoy a healthy lifestyle it is important to suffice these two requirements or else you can see chaos and disaster seen among the people. Food we all know and have been consuming since we were kids, however, this is not the case with sex. The desire to have sexual gratification comes when kids turn adolescent.
So, when it comes to sex life, there are different ways to enjoy it, however, if you look at the core, nothing really has changed since past centuries. Though the lifestyle has changed a lot and would continue changing, however, sex life seems to remain unchanged. You will find various ancients secrets, which can help you in having a good sex life. So how about checking some of the ancient secrets that can really save your sex life in the following paragraphs: (more…)
PASADENA, Calif. — NASA’s Mars rover Curiosity now has a view of a patch of exposed bedrock scientists selected for a few days of close-up study, the first such study since the rover began its long trek to Mount Sharp two months ago. (more…)
Now, after a year spent helping Carissa Wickens, assistant professor in the Department of Animal and Food Sciences (ANFS), set up the organization’s ninth annual conference — hosted collaboratively by UD and the University of Pennsylvania’s New Bolton Center from July 18-20 — Weir is both fully versed in the event and plans to attend the 2014 ISES session in Denmark.

Question: “What did you do this summer?” Answer: “I built the Advanced Light Source.”
It’s the rare undergraduate who can say they spent their vacation building a third-generation synchrotron, but that’s exactly what Seno Rekawa did in the summer of 1991 as an intern at Lawrence Berkeley National Laboratory. It was an auspicious start to his career. Less than five years later, he was working as a full-time engineer at Berkeley Lab and now is a regular mentor to budding high school and college engineers.
Berkeley Lab’s Center for Science and Engineering Education (CSEE), with its range of internship offerings, helps to fulfill one of the Lab’s mandates, which is to inspire and prepare this country’s next generation of scientists, engineers and technicians. This year more than 70 current and recent college students and almost 20 high school and college instructors participated in a CSEE program, working with Berkeley Lab researchers on science projects spanning from cancer research to cosmology to biofuels.

Professor Daniel Davis and his wife Katie’s experience is documented in The Compatibility Gene, published by Penguin, which discusses how our crucial compatibility genes may influence finding a life partner as well as our health and individuality.
Professor Davis said: “We each possess a similar set of around 25,000 human genes. Some of our genes vary from person to person, like those that give us a particular eye or hair colour. But my book is about the few genes – our compatibility genes – that vary the most between each of us. First and foremost these are immune system genes; they control how we combat disease. But recent research shows that they may be even more important than we once thought – there is evidence that they can influence how our brains are wired, how attractive we are, even how likely we are to reproduce.’’ (more…)
