Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point. Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes. In the Nature journal, it is reported about the stable interface between classical and quantum world. (DOI: 10.1038/nature11341) "Normally, every contact with the outer world ...

Chapel Hill, NC – Leukemia and lymphoma patients who receive life-saving stem cell or bone marrow transplants often experience chronic side effects that significantly decrease quality of life, can last a lifetime, and ultimately affect their long-term survival. In chronic Graft vs. Host Disease (GVHD), the differences between the donor bone marrow cells and the recipient's body often cause these immune cells to recognize the recipient's body tissues as foreign and the newly transplanted cells attack the transplant recipient's body. Symptoms can range from dry eyes and ...

While your DNA is unique, it also tells the tale of your family line. It carries the genetic history of your ancestors down through the generations. Now, says a Tel Aviv University researcher, it's also possible to use it as a map to your family's past. Prof. Eran Halperin of TAU's Blavatnik School of Computer Science and Department of Molecular Microbiology and Biotechnology, along with a group of researchers from University of California, Los Angeles, are giving new meaning to the term "genetic mapping." Using a probabilistic model of genetic traits for every coordinate ...

CHAMPAIGN, Ill. — Birds of a feather flock together and – according to a new analysis – so do their lice. A study of the genetic heritage of avian feather lice indicates that their louse ancestors first colonized a particular group of birds (ducks or songbirds, for example) and then "radiated" to different habitats on those birds – to the wings or heads, for instance, where they evolved into different species. This finding surprised the researchers because wing lice from many types of birds look more similar to one another than they do to head or body lice living on the ...

New Rochelle, NY, August 16, 2012—Every year tribal gaming generates billions of dollars in revenue, creates tens of thousands of jobs, and boosts the economies of many Native American communities. In the state of California alone, tribal gaming has brought in $7.5 billion annually. However, because of the aggressive movement to legalize Internet gambling, which effectively would give states the power to regulate and tax online gambling even on reservations, the financial success of these communities could change. In "Native American Off-Reservation Gaming," an expert roundtable ...

After a surgeon stitches up a patient's abdomen, costly complications -- some life-threatening -- can occur. To cut down on these postoperative problems, Johns Hopkins undergraduates have invented a disposable suturing tool to guide the placement of stitches and guard against the accidental puncture of internal organs. The student inventors have described their device, called FastStitch, as a cross between a pliers and a hole-puncher. Although the device is still in the prototype stage, the FastStitch team has already received recognition and raised more than $80,000 ...

Ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta document the region's ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt's Old Kingdom, the era known as the pyramid-building time. "Humans have a long history of having to deal with climate change," said Christopher Bernhardt, a researcher with the U.S. Geological Survey. "Along with other research, this study geologically reveals that the evolution of societies is sometimes tied to climate variability at all scales – whether decadal ...

Lounging on a sofa while watching a 3D movie is an exquisite pleasure for many film fans. Be that as it may, those nettlesome 3D glasses might diminish the fun somewhat. That's why television manufacturers are working on displays that can recreate the spellbinding magic of three-dimensional television images – without the glasses. Though prototypes of these TV screens already exist, consumers will not have to wait much longer for the market introduction of these autostereoscopic displays. Neverthe-less, the content might be a bit problematic: The 3D movies currently available ...

Fairfax, Va.--The popular spice turmeric packs more than just flavor — it shows promise in fighting devastating viruses, Mason researchers recently discovered. Curcumin, found in turmeric, stopped the potentially deadly Rift Valley Fever virus from multiplying in infected cells, says Aarthi Narayanan, lead investigator on the new study and a research assistant professor with Mason's National Center for Biodefense and Infectious Diseases. Mosquito-borne Rift Valley Fever virus (RVF) is an acute, fever-causing virus that affects domestic animals such as cattle, sheep ...

Everyone knows the adage: "If something sounds too good to be true, then it probably is." Why, then, do some people fall for scams and why are older folks especially prone to being duped? An answer, it seems, is because a specific area of the brain has deteriorated or is damaged, according to researchers at the University of Iowa. By examining patients with various forms of brain damage, the researchers report they've pinpointed the precise location in the human brain, called the ventromedial prefrontal cortex, that controls belief and doubt, and which explains why some ...

Ramadan dinners in the Danish Parliament, staff parties without either pork or alcohol and prayer rooms at the airport are all examples of how religion is becoming more visible in public spaces. "Prior to the mass migration of the '60s, '70s and '80s, almost all Danes shared similar values and were members of the national Christian church, so religion was not an issue in everyday life. There was no need to discuss neither one's own nor another person's religious viewpoint, and secularisation was a matter of course. Today, it is difficult to be in a public place, read ...

Astronomers using data from NASA's Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic Cloud, a small satellite galaxy to our Milky Way. What at first was thought to be only one cluster in the core of the massive star-forming region 30 Doradus (also known as the Tarantula Nebula) has been found to be a composite of two clusters that differ in age by about one million years. The entire 30 Doradus complex has been an active star-forming region ...

In the quest to understand how the world's weather moves around the globe, scientists have had to tease apart different kinds of atmospheric movement, such as the great jet streams that can move across a whole hemisphere versus more intricate, localized flows. Much the same must currently be done to understand the various motions at work in the great space weather system that links the sun and Earth as the sun shoots material out in all directions, creating its own version of a particle sea to fill up the solar system. "People think of the sun as giving out light and ...

HOUSTON - A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports in the Aug. 16 issue of Cell. Working in cell lines and mouse models of glioblastoma multiforme, the most lethal form of brain tumor, senior author Zhimin Lu, Ph.D., associate professor of Neuro-Oncology at MD Anderson, and colleagues show that pyruvate kinase M2 (PKM2) fuels tumor growth by influencing a histone protein. DNA ...

PHILADELPHIA, August 16, 2012 – Without other risk factors, all Americans born between 1945 and 1965 should have a one-time screening for the hepatitis C virus (HCV) according to new recommendations being published early online today in Annals of Internal Medicine, the flagship journal of the American College of Physicians. The Centers for Disease Control and Prevention (CDC) also recommends that all persons identified with HCV should receive a brief alcohol screening and intervention and be referred to appropriate care and treatment services for HCV and related conditions. Up ...

MINNEAPOLIS – People who are free of dementia and have high levels of a protein that indicates the presence of inflammation have relatives who are more likely to avoid the disease as well, according to a new study published in the August 15, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. "In very elderly people with good cognition, higher levels of C-reactive protein, which is related to inflammation, are associated with better memory," said study author Jeremy M. Silverman, PhD, with Mount Sinai School of Medicine in New ...

An early age at first drink (AFD) has been linked to later alcohol-related problems, which is one of the reasons behind the legal drinking age of 21 in the U.S. It is unclear, however, if increased risk is primarily due to initiation of any drinking, or initiation of heavier drinking. A comparison of the influence of these potential risk factors among college undergraduates found that both an early AFD as well as a quick progression from the first drink to drinking to intoxication independently predicted later problems. Results will be published in the November 2012 ...

Not only have energy drinks become increasingly popular among adolescents and young adults in recent years, so too has mixing and drinking them with alcohol. However, research on the subjective psychological, physiological, and behavioral risk-taking outcomes of alcohol/energy drinks has had mixed results. A first-of-its-kind study compares the outcomes of alcohol/energy drinks with alcohol-only drinks among members of the Australian public. Results will be published in the November 2012 issue of Alcoholism: Clinical & Experimental Research and are currently available ...

Many studies have found that problem drinking is related to subsequent unemployment; however, the reverse association is unclear. Some studies have found that unemployment can increase total drinking, alcohol disorders, and/or problem drinking while others have found that unemployment can decrease drinking or have no effect at all. An analysis of binge drinking as either a predictor or outcome of unemployment has found that binge drinking among women seems to have a significant association with long-term unemployment. Results will be published in the November 2012 ...

HOUSTON – (Aug.15, 2012) – A study by a Baylor College of Medicine physician-researcher has shed light on the most effective treatment for adults with Langerhans cell histiocytosis (LCH) in bones. LCH is a disease that can affect the skin, mouth, ears, bones, brain, gastrointestinal system, liver, spleen, or bone marrow. In the study, appearing in the current issue of PLOS ONE, researchers reviewed health records for 58 adults with the disease and compared the effectiveness of three chemotherapy treatments – vinblastine/prednisone, 2-Chlorodeoxyadenosine, and cytosine ...

A paper published 15 August 2012 in Biology of Reproduction's Papers-in-Press reveals that eating 75 grams of walnuts a day improves the vitality, motility, and morphology of sperm in healthy men aged 21 to 35. Approximately 70 million couples experience subfertility or infertility worldwide, with 30 to 50 percent of these cases attributable to the male partner. Some studies have suggested that human semen quality has declined in industrialized nations, possibly due to pollution, poor lifestyle habits, and/or an increasingly Western-style diet. Dr. Wendie Robbins and ...

An investigational drug currently under FDA review for the treatment of rheumatoid arthritis has now shown positive results in patients with moderate-to-severe ulcerative colitis, according to researchers at the University of California San Diego, School of Medicine. The study will appear in the August 16, 2012 issue of the New England Journal of Medicine (NEJM). Results from the phase 2 clinical trial showed the drug Tofacitinib achieved clinical response and remission in certain patients suffering from ulcerative colitis – a chronic inflammatory disease of the colon ...

A previously unrecognized system that drains waste from the brain at a rapid clip has been discovered by neuroscientists at the University of Rochester Medical Center. The findings were published online August 15 in Science Translational Medicine. The highly organized system acts like a series of pipes that piggyback on the brain's blood vessels, sort of a shadow plumbing system that seems to serve much the same function in the brain as the lymph system does in the rest of the body – to drain away waste products. "Waste clearance is of central importance to every organ, ...
