(Press-News.org) WASHINGTON, July 14, 2014 — Chances are those dollars in your pocket have a trace of cocaine on them. Don't worry — most bank notes in the U.S. do. Your cash also contains invisible ink and has likely been through a washing machine before it came out of the ATM. For more, watch this week's Reactions episode, which features a stack of chemistry facts about the almighty dollar. The video is available at http://youtu.be/bAIwFaPycaU.

Scientists developed new technology for the diagnosis of cancer cells
2014-07-14
Together with the company Tissuegnostics, the pathologist Lukas Kenner and his colleagues have developed a software that is able to identify cancer cells in tissue sections and demonstrate the presence of specific biomarkers on cells. The overall information provides a precise picture of the disease and leads to the most suitable treatment.
According to the results of the study, "Two independent pathologists concur with each other only in regard of every third diagnosis."
"The recently developed software offers, for the first time, the option of eliminating the so-called ...
Study rebuts negative reputation of 'No Child Left Behind'
2014-07-14
The public perception that No Child Left Behind has increased burnout and lowered job satisfaction among teachers is unfounded, according to a recent study co-authored by UT Dallas researcher Dr. James R. Harrington.
The study, which was published online in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association, found that, overall, the accountability pressures of No Child Left Behind (NCLB) did not have much of an impact on teachers' job satisfaction or commitment to the profession.
NCLB is the latest version ...
Bothered by hot flashes? Acupuncture might be the answer
2014-07-14
CLEVELAND, Ohio (July 14, 2014)—In the 2,500+ years that have passed since acupuncture was first used by the ancient Chinese, it has been used to treat a number of physical, mental and emotional conditions including nausea and vomiting, stroke rehabilitation, headaches, menstrual cramps, asthma, carpal tunnel, fibromyalgia and osteoarthritis, to name just a few. Now, a meta-analysis of randomized controlled trials which is being published this month in Menopause, the journal of The North American Menopause Society (NAMS), indicates that acupuncture can affect the severity ...
Squishy robots
2014-07-14
In the movie "Terminator 2," the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed.
Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
The material — developed by Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and her former graduate student Nadia Cheng, alongside researchers at the Max Planck Institute for Dynamics and Self-Organization and Stony ...
University of Illinois researchers demonstrate novel, tunable nanoantennas
2014-07-14
A research team from the University of Illinois at Urbana-Champaign has developed a novel, tunable nanoantenna that paves the way for new kinds of plasmonic-based optomechanical systems, whereby plasmonic field enhancement can actuate mechanical motion.
"Recently, there has been a lot of interest in fabricating metal-based nanotextured surfaces that are pre-programmed to alter the properties of light in a specific way after incoming light interacts with it," explained Kimani Toussaint, an associate professor of mechanical science and engineering who led the research. ...
Proof: Parkinson's enhances creativity
2014-07-14
Prof. Rivka Inzelberg of Tel Aviv University's Sackler Faculty of Medicine and the Sagol Neuroscience Center at Sheba Medical Center, Tel Hashomer, documented the exceptional creativity of Parkinson's patients two years ago in a review for Behavioral Neuroscience. Since then, she has conducted the first empirical study to verify a link between Parkinson's disease and artistic inclination.
That empirical study, now published in the Annals of Neurology, definitively demonstrates that Parkinson's patients are more creative than their healthy peers, and that those patients ...
Innovative technique may transform the hunt for new antibiotics and cancer therapies
2014-07-14
Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process.
In a study reported in ACS Chemical Biology, University of Illinois researchers developed a new technique to quickly uncover novel, medically relevant products produced by bacteria.
Past techniques involved screening more than 10,000 samples to find a novel product, said principal investigator Doug Mitchell, assistant professor of chemistry and Institute for Genomic ...
Cancer is avoidable as you grow older. Here's how.
2014-07-14
Is cancer an inevitable consequence of aging?
Although it is widely thought that cancer is an inevitable consequence of aging, the risk of developing several common cancers decreases with age.
Researchers have long been puzzled by the apparent decrease with age in the risk of developing certain adult cancers.
A possible solution to this puzzle was presented in a recent paper published in Biophysical Reviews and Letters by Professor James P. Brody of the Department of Biomedical Engineering at the University of California, Irvine.
"Most cancers have a characteristic ...
Manuel Serrano proposes a new vision of a process wrongly associated with ageing
2014-07-14
For the Spanish Royal Academy, senescent is he who "begins to age". But laboratory biology results are contradicting the dictionary: not only is senescence not a synonym of ageing, it is also not intrinsically negative for the organism. Cellular senescence is such a badly named physiological process that those who do research in this area think it needs another name. That is the case of Manuel Serrano, from the Spanish National Cancer Research Centre (CNIO), one of the world's leading experts on senescence, who has just published a review on this topic. Without actually ...
Validity of change in DSM-5 ADHD age of onset criterion confirmed
2014-07-14
Washington D.C., July 14, 2014 – A recent study published in the July 2014 issue of the Journal of the American Academy of Child and Adolescent Psychiatry confirms the validity of the DSM-5 change to the age of onset criterion for diagnosis of attention-deficit/hyperactivity disorder (ADHD).
In DSM-5, age of onset criterion for ADHD, previously set at 7 in DSM-IV, has been raised to 12. As explained in DSM-5, age of onset is now set at 12, rather than an earlier age, to reflect the importance of clinical presentation during childhood for accurate diagnosis, while also ...
