Calculations by researchers at the University of California, San Francisco and the University of California, Berkeley estimate that the cancer risk associated with one type of airport security scanners is low based on the amount of radiation these devices emit, as long as they are operated and function correctly. "The doses are low – extremely low," said Rebecca Smith-Bindman, MD, a professor of radiology at UCSF, who made the calculations with Pratik Mehta, an undergraduate at UC-Berkeley. "The amount of radiation in these scans is so low that you don't have to be concerned ...

COLUMBUS, Ohio – Engineers at Ohio State University have invented a new kind of nano-particle that shines in different colors to tag molecules in biomedical tests. These tiny plastic nano-particles are stuffed with even tinier bits of electronics called quantum dots. Like little traffic lights, the particles glow brightly in red, yellow, or green, so researchers can easily track molecules under a microscope. This is the first time anyone has created fluorescent nano-particles that can change colors continuously. Jessica Winter, assistant professor of chemical and ...

Conception is a blessed event, be it a child's, or a new book. That is novelist Josie Brown's contention. She should know. The idea for her fourth novel, The Baby Planner [Simon & Schuster/Gallery Books]--about a childless woman who channels her nurturing instincts toward her pregnant clients--was born in the reception area of her mammogram center. "I picked up the only reading material available: a local parenting magazine," explains Brown, who lives in the San Francisco Bay Area. "My own children are older, so it wasn't necessarily something I felt might interest ...

Between 75 and 80 per cent of all volcanic activity on Earth takes place at deep-sea, mid-ocean ridges. Most of these volcanoes produce effusive lava flows rather than explosive eruptions, both because the levels of magmatic gas (which fuel the explosions and are made up of a variety of components, including, most importantly CO2) tend to be low, and because the volcanoes are under a lot of pressure from the surrounding water. Over about the last 10 years however, geologists have nevertheless speculated, based on the presence of volcanic ash in certain sites, that explosive ...

Last week, the Michigan Catastrophic Claims Associations (MCCA) announced it would be instituting a slight fee increase that will be passed on to policyholders in the state. Car insurance providers currently are required to pay the MCCA $143.09 per insured vehicle, which gets incorporated into the premiums of even the cheapest auto insurance companies in the state. That amount will be raised 1.3 percent starting in July. The fee revenue goes into an MCCA-administered fund that exists as a result of the unorthodox structure of Michigan's no-fault system. Unlike the ...

By taking a closer look at animal bones scattered across the wilderness landscape, a researcher at the University of Chicago has found a powerful tool for showing how species' populations have changed over decades or even a century. "The skeletons of long-dead animals lying on landscapes provide critical insight into our understanding of ecosystem history, especially how populations have changed," said the study's author, University of Chicago alumnus Joshua H. Miller, S.M.'05, PhD'09, a postdoctoral research fellow in biological sciences at Wright State University in ...

The statement was written by 20 leading experts in diabetes and bariatric surgery who have made a series of recommendations on the use of weight-loss surgery as a cost-effective treatment option for ...

Just like snowflakes, no two people are alike, even if they're identical twins according to new genetic research from The University of Western Ontario. Molecular geneticist Shiva Singh has been working with psychiatrist Dr. Richard O'Reilly to determine the genetic sequencing of schizophrenia using identical or monozygotic twins. The study is published in this month's PLoS ONE. Singh looked at about one million markers of identical twins (and their two parents) where only one twin had schizophrenia. "The most informative feature of schizophrenia is that it sometimes ...

RIVERSIDE, Calif. – How exactly bacterial pathogens cause diseases in plants remains a mystery and continues to frustrate scientists working to solve this problem. Now Wenbo Ma, a young plant pathologist at the University of California, Riverside, has performed research on the soybean plant in the lab that makes major inroads into our understanding of plant-pathogen interactions, a rapidly developing area among the plant sciences. Her breakthrough research can help scientists come up with effective strategies to treat crops that have succumbed to disease or, when used ...

Researchers at Mount Sinai School of Medicine have found that patients with Alzheimer's disease have lower glucose utilization in the brain than those with normal cognitive function, and that those decreased levels may be detectable approximately 20 years prior to the first symptoms of Alzheimer's disease. This new finding could lead to the development of novel therapies to prevent the eventual onset of Alzheimer's. The study is published online in the journal Translational Neuroscience. Using mice modified to develop Alzheimer's disease, the research team found that ...

Icebergs cool and dilute the ocean water they pass through and also affect the distribution carbon-dioxide-absorbing phytoplankton in the Southern Ocean, according to a team of researchers from UC San Diego and the University of San Diego. The effects are likely to influence the growth of phytoplankton in the Atlantic sector of the Southern Ocean and especially in an area known as "Iceberg Alley" east of the Antarctic Peninsula. Enhanced phytoplankton growth would increase the rate at which carbon dioxide is removed from the ocean, an important process in the carbon ...

A team of scientists has discovered that descendants of "exploratory" butterflies that colonized new habitats differ genetically from their more cautious cousins. The team, led by James Marden, a professor of biology at Penn State University, and Christopher Wheat, a post-doctoral scholar working at both Penn State and the University of Helsinki, has revealed some of the genetic bases for faster egg maturation, a higher rate of energy metabolism, and superior flight ability -- traits that provide an advantage to butterflies that stray from familiar territory to found new ...

Wind is a much more powerful force in the evolution of mountains than previously thought, according to a new report from a University of Arizona-led research team. Bedrock in Central Asia that would have formed mountains instead was sand-blasted into dust, said lead author Paul Kapp. "No one had ever thought that wind could be this effective," said Kapp, a UA associate professor of geosciences. "You won't read in a textbook that wind is a major process in terms of breaking down rock material." Rivers and glaciers are the textbook examples of forces that wear down ...

For a long time, Amazon.com shoppers throughout the United States have found themselves constantly searching for promotional and discount codes for the products they wish to purchase or are interested in. Whilst there are many websites online which offer such codes, few (if any) focus solely on the Amazon market. This often results in inaccurate codes, untargeted deals and ultimately a waste of the browsers' time.

TORONTO, ON – With birds chirping and temperatures warming, spring is finally in the air. But for University of Toronto Scarborough (UTSC) environmental chemist Torsten Meyer, springtime has a dark side. "During the winter months, contaminants accumulate in the snow," says Meyer, an expert on snow-bound organic contaminants and a post-doctoral fellow at UTSC. "When the snow melts, these chemicals are released into the environment at high concentrations." In a specially designed, temperature-controlled laboratory at UTSC—which includes a homemade snow-gun and a chemical ...

Two teams – one dedicated to the patient – and the other to the donor arm – successfully completed the surgery at approximately ...

Stigma against overweight people is becoming a cultural norm around the world, even in places where larger bodies have traditionally been valued. That's according to a cross-cultural study of attitudes toward obesity to be published in the April issue of Current Anthropology. Researchers from Arizona State University surveyed people in nine diverse locations around the world and found negative attitudes toward fat bodies in every one. The results suggest a rapid "globalization of fat stigma" in which overweight people are increasingly viewed as ugly, undesirable, lazy, ...

A researcher at Case Western Reserve University has detected tiny amounts of Iodine 131 from Japan in rainwater collected from the roof of a campus building. Gerald Matisoff, professor of geology, said the presence of the isotope presents no danger to human health. He estimated the level of radiation is about one-tenth that of natural background radiation. "In theory, the Iodine 131 could have come from any radioactive waste processing facility," Matisoff said. "But, we know it's from Japan. The isotope is being seen worldwide." Matisoff and graduate student Mary ...
