"Wash away my troubles, wash away my pain," goes the song. Is there such a thing as soap and water for the psyche? Yes: Metaphor is that powerful, say Spike W.S. Lee and Norbert Schwarz of the University of Michigan in a literature review appearing in the latest issue of Current Directions in Psychological Science, a journal published by the Association for Psychological Science.

STANFORD, Calif. — Carefully tracking the rate of response of human lung tumors during the first weeks of treatment can predict which cancers will undergo sustained regression, suggests a new study by researchers at the Stanford University School of Medicine.
Cold Spring Harbor, N.Y. – A new study from Cold Spring Harbor Laboratory (CSHL) reports surprising results that suggest that the devastating neuromuscular disease, spinal muscular atrophy (SMA), might not exclusively affect the motor neurons in the spinal cord as has long been thought. The new findings suggest that defects in peripheral tissues such as liver, muscle, heart, etc., might also contribute to the pathology of the disease in severely affected patients.
Women donating their eggs for use in fertility clinics are typically financially compensated for the time and discomfort involved in the procedure. However, guidelines established by the National Academy of Sciences (NAS) in 2005 state that women who donate their eggs for use in stem cell research should not be compensated, although the procedures they undergo are the same.
Conditions like atherosclerosis and age-related macular degeneration (AMD) -- the most common cause of blindness among the elderly in western societies -- are strongly linked to increased oxidative stress, the process in which proteins, lipids and DNA damaged by oxygen free radicals and related cellular waste accumulate, prompting an inflammatory response from the body's innate immune system that results in chronic disease.
Why are some places more prone to bribery and corruption than others? Part of the answer seems to be the level of collective feeling in a society, according to research by Pankaj Aggarwal, University of Toronto Scarborough (UTSC) professor of marketing in the Department of Management, and Nina Mazar, University of Toronto professor of marketing.
CHAMPAIGN, Ill. — Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical soup out of which evolution gradually constructed more complex forms. Some scientists still debate whether it was even a cell.
New evidence suggests that LUCA was a sophisticated organism after all, with a complex structure recognizable as a cell, researchers report.
The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged by this process. A group of specialized bacteria perform the anammox reaction, but so far scientists have been in the dark about how these bacteria could convert ammonia to nitrogen in the complete absence of oxygen. Now, 25 years after its discovery, they finally solved the molecular mechanism of anammox.
The examination of insects in Burmese amber by researchers at the University of Cologne, Germany and National Museums Scotland revealed a new genus of caddisfly, which has been named Palerasnitsynus.
In a study recently published in European Physical Journal E (EPJE), a German scientist constructed a theoretical model to understand how to best avoid jamming of soft matter that can be applied in food and cosmetics production.
Thomas Voigtmann, a researcher at the Institute for Material Physics in Space in Cologne, Germany, evaluated the internal friction force, or yield stress, to be overcome before a solid material made of a metallic melt with a glass structure can flow and thus prevent jamming.
New research by scientists at the University of Southampton has shown how London's trees can improve air quality by filtering out pollution particulates, which are damaging to human health.
A paper published this month in the journal Landscape and Urban Planning indicates that the urban trees of the Greater London Authority (GLA) area remove somewhere between 850 and 2000 tonnes of particulate pollution (PM10) from the air every year.
A team of researchers from the Capital Normal University in Beijing (China) and the Institute of Biology and Soil Sciences in Vladivostok (Russia) has discovered a remarkable silky lacewing insect from the Mesozoic of China. The study has been published recently in the open access journal ZooKeys and is available for free download.
Dietary supplements for patients after lung injury do not appear to improve outcomes; may be harmful
CHICAGO – In contrast to findings of previous studies, patients who experienced an acute lung injury, such as from pneumonia or sepsis, and received dietary supplements including omega-3 fatty acids and antioxidants had more days on a ventilator, more days in the intensive care unit (ICU), and a non-statistically significant increase in the rate of death, according to a study appearing in JAMA. The study is being published early online to coincide with its presentation at the European Society of Intensive Care Medicine meeting in Berlin.
Halle/Saale and Berlin. Scientists present the largest distribution data compilation ever on butterflies of an entire continent. The Germany based Society for the Conservation of Butterflies and Moths GfS ("Gesellschaft für Schmetterlingsschutz"), the German Nature Conservation Association NABU ("Naturschutzbund Deutschland") and the Helmholtz-Centre for Environmental Research (UFZ) are delighted to announce the publication of the „Distribution Atlas of Butterflies in Europe".
There are many reasons why people with chronic kidney disease (CKD) often lose fitness and have increasing difficulty performing normal daily tasks, but new research shows scientific evidence for the benefits of regular exercise for people with CKD, including those with a kidney transplant. They can improve their physical fitness, walk further, have healthier blood pressures, healthier heart rates, higher health-related quality of life scores and better nutritional characteristics compared to those who don't exercise. So concludes a systematic review published in The Cochrane Library.
