A team of scientists has described two cladocerous crustaceans, which could be endemic to the Iberian Peninsula, and which were found in two lagoons, one in the lower basin of the Guadalquivir river, and the other in the grasslands of Extremadura. Both of these arthropods may today inhabit more areas in the Mediterranean region. "These two new crustaceans (Leydigia) are a species of living fossil and are very powerful bio-geographic and historical indicators", Miguel Alonso, one of the authors of the study, and a researcher in the Department of Ecology of the University ...

For the first time, quantitative—not qualitative—data analysis has demonstrated that time-of-flight (TOF) positron emission tomography (PET) scans can improve cancer detection. Research published in the March issue of the Journal of Nuclear Medicine shows that oncologic TOF fluorodeoxyglucose (FDG) PET scans yielded significant improvements in lesion detection of lung and liver cancers over all contrasts and body mass indexes. Conventional PET scans create images by detecting gamma rays produced by radioisotopes that are injected into the body. Although these conventional ...

To determine if a tissue biopsy reveals the presence of cancer, a histologist often screens for cells with an abnormal appearance or a specific visible trait such as a larger-than-usual nucleus. However, by the time a cancer is physically noticeable, the disease may be in its later stages and more difficult to treat. In an effort to identify the earlier-onset, more subtle chemical changes occurring in a cell heading toward malignancy, researchers at the National Institute of Standards and Technology (NIST) and the National Cancer Institute (NCI) have developed a technique ...

The current edition of JAMIA, today's top-ranked journal in biomedical and health informatics, features new scientific research—in print and online—on some of healthcare's most hotly discussed HIT-related topics, written by prominent experts working in health and biomedicine: "The case for randomized controlled trials to assess the impact of clinical information systems" Joseph L.

BOZEMAN, Mont. –- Solar scientists from around the world were puzzled when sunspots recently disappeared for more than two years, but a former Montana State University physics graduate student and two collaborators have solved the mystery. In the process, they found a way to predict the next lapse in solar activity, which will help people who oversee communication systems or plan long trips into space, said MSU solar physicist Piet Martens. Dibyendu Nandi, Andres Munoz-Jaramillo and Martens published a paper in the March 3 issue of Nature that they said explained for ...

Lower potassium levels in the blood may help explain why African-Americans are twice as likely to be diagnosed with type 2 diabetes as whites, according to a new study by Johns Hopkins researchers. The findings, if confirmed, suggest that part of diabetes prevention may someday prove as easy as taking a cheap potassium supplement. "This research doesn't mean people should run out and start taking potassium supplements," says Hsin-Chieh "Jessica" Yeh, Ph.D., an assistant professor of medicine at the Johns Hopkins University School of Medicine and an author of the study, ...

A retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig's disease. The finding, made by Johns Hopkins scientists, may eventually give researchers a new way to attack this universally fatal condition. While roughly 20 percent of ALS cases appear to have a genetic cause, the vast majority of cases appear to arise sporadically, with no known trigger. Research groups searching for a cause of this so-called sporadic form had ...

An international consortium of researchers led by Universitat Autònoma de Barcelona (UAB) genetically characterises almost all Spanish patients and studies the clinical impact of the mutations. The study describes over 130 pathogenic mutations and the origins and world distribution of some of the most frequent mutations. The predominant genetic mutation originated in Europe thousands of years ago and later migrated to America. The Canary island of La Palma and Brazil, with a high prevalence of the disease, were two areas in which the mutation spread widely. A consortium ...

Scientists are reporting the first evidence that consumption of a healthful antioxidant substance in apples extends the average lifespan of test animals, and does so by 10 percent. The new results, obtained with fruit flies — stand-ins for humans in hundreds of research projects each year — bolster similar findings on apple antioxidants in other animal tests. The study appears in ACS's Journal of Agricultural and Food Chemistry. Zhen-Yu Chen and colleagues note that damaging substances generated in the body, termed free radicals, cause undesirable changes believed to ...

WEST LAFAYETTE, Ind. - A Purdue University scientist and researchers in Japan have produced a new class of improved plant growth regulators that are expected to be less toxic to humans. Angus Murphy, a professor of horticulture, said the growth inhibitors block the transport of auxin, a plant hormone that, when transported throughout the plant, controls growth processes. Current growth regulators that inhibit auxin transport are inefficient because they also have hormonelike activity or affect other important plant processes. Current growth inhibitors also are often toxic. Growth ...

Scientists are reporting discovery of a protein in the blood of lung cancer patients that could be used in a test for the disease — difficult to diagnose in its earliest and most treatable stages — and to develop drugs that stop lung cancer from spreading. Their study appears in ACS's Journal of Proteome Research. In the report, Je-Yoel Cho and colleagues note that lung cancer is the leading cause of cancer deaths worldwide. Lung cancer is so deadly because of its tendency to spread — or metastasize — to distant sites in the body, such as the liver or the brain. Early ...

Technological progress may be fast-paced in many fields, but one mundane area has been almost left in the doldrums for the last 150 years: The basic technology for permanently coloring hair. That's the conclusion of an analysis of almost 500 articles and patents on the chemistry of permanent hair dyeing, which foresees much more innovation in the years ahead, including longer lasting, more-natural-looking dyes and gene therapy to reverse the gray. The article appears in ACS's journal Chemical Reviews. Robert Christie and Olivier Morel note that hair dye already is a multibillion ...

In a study that the authors describe as lending credence to the idiom, "by the skin of your teeth," scientists are reporting that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. It raises questions about how this renowned cavity-fighter really works and could lead to better ways of protecting teeth from decay, the scientists suggest. Their study appears in ACS's journal Langmuir. Frank Müller and colleagues point out that tooth decay is a major public health problem worldwide. In the United States alone, consumers spend ...

Real-life scientists, whose work has overtones of Indiana Jones as they search for plants in remote areas of the world that could become the source of life-saving new medicines, are currently trying to figure out how a new international agreement on biodiversity will affect their work. That's the topic of an article in Chemical & Engineering News (C&EN), ACS's weekly newsmagazine. C&EN Associate Editor Carmen Drahl explains that environment ministers from 200 countries hammered out the agreement late last year. Called the Nagoya protocol, it extends a 1993 United Nations ...

For the first time, scientists discovered that a specific type of human cell, generated from stem cells and transplanted into spinal cord injured rats, provide tremendous benefit, not only repairing damage to the nervous system but helping the animals regain locomotor function as well. The study, published today in the journal PLoS ONE, focuses on human astrocytes – the major support cells in the central nervous system – and indicates that transplantation of these cells represents a potential new avenue for the treatment of spinal cord injuries and other central nervous ...

RIVERSIDE, Calif. – Rice, which is sensitive to drought due to its high water requirement, is particularly vulnerable to how global climate change is altering the frequency and magnitude of floods and droughts. If rice plants' combined tolerance to flooding and drought could be improved, however, rice productivity could be protected and even substantially increased. Now plant scientists at the University of California, Riverside have made a discovery that can greatly benefit rice growers and consumers everywhere. The researchers have demonstrated in the lab and greenhouse ...

CHAMPAIGN, Ill. – New research by a University of Illinois expert in employment relations and labor economics shows that, for more than a decade, Wisconsin teacher salaries have fallen behind changes in the cost of living as well as wage growth in the private sector. Craig A. Olson, a professor of labor and employment relations, says the salaries of Wisconsin teachers have lost ground to those of their private sector counterparts over the last 16 years. The paper compares the earnings of an average college graduate employed in the private sector in the U.S. versus the ...
