Quantum measurements: Common sense is not enough
Report offers principles for maintaining the integrity and accessibility of research data
In comparison to classical physics, quantum physics predicts that the properties of a quantum mechanical system depend on the measurement context, i.e., whether other system measurements are carried out. A team of physicists from Innsbruck, Austria, led by Christian Roos and Rainer Blatt, have for the first time proven in a comprehensive experiment that it is not possible to explain quantum...
Risky driving puts P-platers at high danger of crash
Though digital technologies and high-speed communications have significantly expanded the capabilities of scientists -- allowing them to analyze and share vast amounts of data -- these technologies are also raising difficult questions for researchers, institutions and journals.
Scientists link immune system's natural killer cells to infant liver disease
Australia's largest study of young drivers has shown that risky driving habits are putting young drivers at a significantly increased risk of crashing, irrespective of their perceptions about road safety. The study surveyed 20,000 young drivers and examined their crashes reported to police. Young drivers involved in the study who said they undertook risky driving were 50 percent more likely to...
Scientists shed new light on cause of inherited movement disorder
Scientists have linked an overactive response by one of the immune system's key weapons against infection -- natural killer cells -- to biliary atresia in infants, a disease where blocked bile ducts can cause severe liver damage and death. The study, to appear in the Aug. 3 Journal of Clinical Investigation, shows blocking a gene that helps NK cells attack bile duct tissues may be a way to treat a...
Still a low chance of development for 2 lows
University of Utah School of Medicine researchers and their colleagues at University of Texas Southwestern Medical Center have found strong evidence that abnormal calcium signaling in neurons may play an important role in the development of spinocerebellar ataxia type 2 (SCA2), a disorder causing progressive loss of coordination, speech difficulty and abnormal eye movements. Their findings are...
Stop and smell the flowers -- the scent really can soothe stress
The two areas of thunderstorms in the Caribbean from yesterday, July 21, are on the move. One area is now moving into out of the Caribbean and into the eastern Atlantic Ocean while the other is now moving over the southeastern Bahamas and Hispaniola on a northwest track.
Study provides documentation that tumor 'stem-like cells' exist in benign tumors
Feeling stressed? Then try savoring the scent of lemon, mango, lavender or other fragrant plants. Scientists in Japan are reporting the first scientific evidence that inhaling certain fragrances alter gene activity and blood chemistry in ways that can reduce stress levels. Their study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.
The benefit of migration
Cancer stem-like cells have been implicated in the genesis of a variety of malignant cancers. Research scientists at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have isolated stem-like cells in benign (pituitary) tumors and used these "mother" cells to generate new tumors in laboratory mice. Targeting the cells of origin is seen as a possible strategy in the fight against...
The value of variation: Ecologists consider the causes and consequences
Immigrants from the eight Central and Eastern European countries that joined the EU in 2004 are less likely to be claiming welfare benefits and less likely to be living in social housing than people born in the UK. What is more, they have made a positive contribution to the UK fiscal system, paying more in taxes than they receive in direct and indirect public transfers (such as benefits, NHS...
The Virus That Binds: A Novel Idea Marries Biology And Mining
Understanding the ecological causes and consequences of ecological variation is the goal of a group of scientists meeting at the National Institute for Mathematical and Biological Synthesis at the University of Tennessee, Knoxville, July 27-29.

UC scientists determine that ancient Maya practiced forest conservation -- 3,000 years ago
Researchers often make progress by applying a proven scientific method from one realm to another, connecting seemingly disparate disciplines. Such interdisciplinary approaches are powerful tools in the drive for scientific innovation. But who would ever dream of applying viruses to...
Vaccine blocks malaria transmission in lab experiments
An interdisciplinary team led by paleoethnobotanist David Lentz of the University of Cincinnati has concluded that not only did the Maya people practice forest management, but when they abandoned their forest conservation practices it was to the detriment of the entire Maya culture. This visit, the first allowed by the Guatemalan government by a North American university in more than 40 years, is...
Vi typhoid vaccine proves highly effective in young children
Researchers at the Johns Hopkins Malaria Research Institute have for the first time produced a malarial protein (Pfs48/45) in the proper conformation and quantity to generate a significant immune response in mice and non-human primates for use in a potential transmission-blocking vaccine. Antibodies induced by Pfs48/45 protein vaccine effectively blocked the sexual development of the...
Vyvanse CII significantly improved ADHD symptoms for children 13 hours after administration
A new study has found that a currently available yet underused vaccine against typhoid fever is highly effective in young children and protects unvaccinated neighbors of vaccinees.
When food gets inspected and recalled, consumers may not get a clear picture of the process
Shire announced a study published in Child and Adolescent Psychiatry and Mental Health found once-daily Vyvanse (lisdexamfetamine dimesylate) CII significantly reduced the symptoms of ADHD in children aged 6 to 12 years from the first time point measured (1.5 hours) up to the last time point assessed (13 hours) after administration. These published data are the first to show duration of effect...
Yale researchers find key 'conductor' of nature's synchronicity
What consumers may not be finding out about recalls and the inspection process could make them doubt the effectiveness of what is actually a pretty good system to keep food safe. Researchers looked at what information consumers can take away from the Food Safety and Inspection Service's Web site and suggest government agencies can more clearly communicate their role in keeping the food supply...
Yerkes plays vital role in study challenging prevailing view of AIDS in nonhuman primates
Researchers at Yale University and the University of Calgary report in the July 22 issue of Nature's advanced online publication that predator-prey interactions are the "conductors" of synchronicity in living organisms.
Ytterbium's broken symmetry
Researchers at Yerkes National Primate Research Center, Emory University, contributed key comparative data for a landmark study showing African wild chimpanzees infected with simian immunodeficiency virus, an HIV-1-like virus, die prematurely and develop hallmarks of HIV-1 infection and AIDS.
Parental Stress Boosts Kids' Asthma Risk
The weak interaction has the shortest range of the fundamental forces and does some of the most peculiar things, like changing the flavor of quarks, governing the interactions of neutrinos, and violating parity -- nature's mirror symmetry. In ytterbium, researchers in Lawrence Berkeley National Laboratory's Nuclear Science Division and the University of California at Berkeley have measured the...
