Scientists discover new bat species in West Africa

2013-09-03
(Press-News.org) An international team of scientists, including biologists from, the University of York, has discovered five new species of bats in West Africa.

The team, which also included researchers from the Czech University of Life Sciences and the Academy of Sciences, Charles University in the Czech Republic, discovered a wealth of unexpected diversity among Vesper bats in Senegal.

During seven expeditions to the Niokolo-Koba National Park in south-eastern Senegal, and subsequent genetic analysis, the scientists discovered that five species of bats looked similar to other populations in Africa, but differed significantly genetically from them.

Taxonomists are now working on describing formally these new species – Vesper bats (Vespertilionidae) are already the largest family of bats with more than 400 known species. The research is published in Frontiers in Zoology.

The researchers studied 213 vespertilionid bats from Senegal and identified ten species, five of which were significantly genetically different from their nominate species -- Pipistrellus hesperidus, Nycticeinops schlieffenii, Scotoecus hirundo, Neoromicia nana and Neoromicia somalica.

One of the research team, Nancy Irwin, of the Department of Biology at York, says: "The fact that these Senegalese bats are unrelated and are different to their cousins in other parts of Africa, suggests that West Africa may have been isolated in the past and formed a refugium, where populations gradually diverged and even acquired new chromosomal configurations. "This exciting finding confirms that West Africa may represent an underestimated bio-geographic hotspot with many more species to discover."

New evidence to aid search for charge 'stripes' in superconductors

2013-09-03
UPTON, NY - Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a series of clues that particular arrangements of electrical charges known as "stripes" may play a role in superconductivity-the ability of some materials to carry electric current with no energy loss. But uncovering the detailed relationship between these stripe patterns and the appearance or disappearance of superconductivity is extremely difficult, particularly because the stripes that may accompany superconductivity are very likely moving, or fluctuating. As ...

Researchers propose a new system for quantum simulation

2013-09-03
Researchers from the universities in Mainz, Frankfurt, Hamburg and Ulm have proposed a new platform for quantum simulation. In a theoretical paper recently published in Physical Review Letters, they show that a combined system of ultracold trapped ions and fermionic atoms could be used to emulate solid state physics. This system may outperform possibilities of existing platforms as a number of phenomena found in solid state systems are naturally included, such as the fermionic statistics of the electrons and the electron-sound wave interactions. Quantum simulation was ...

Ground breaking research identifies promising drugs for treating Parkinson's

2013-09-03
New drugs which may have the potential to stop faulty brain cells dying and slow down the progression of Parkinson's, have been identified by scientists in a pioneering study which is the first of its kind. Experts from the world leading Sheffield Institute for Translational Neuroscience (SITraN) conducted a large scale drugs trial in the lab using skin cells from people with this progressive neurological condition which affects one in every 500 people in the UK. The researchers tested over 2,000 compounds to find out which ones could make faulty mitochondria work ...

Nursing students lack effective role models for infection prevention: Study

2013-09-03
Washington, DC, September 3, 2013 – 100 percent of student nurses surveyed observed lapses in infection prevention and control practices during their clinical placements, according to a British study published in the September issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC). Infection prevention and control (IPC) education is a fundamental component of the nursing curriculum, but little is understood about nursing students' experience of IPC in the clinical setting ...

Can you predict complications with back surgery? Preoperative factors increase risk

2013-09-03
Philadelphia, Pa. (September 1, 2013) - For older adults undergoing surgery for spinal stenosis, some simple indicators of poor preoperative health predict a high risk of major medical complications, reports a study in the September 1 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. In combination, these risk factors may help in identifying patients at increased risk of heart attack and other serious events after spinal stenosis surgery, according to the report by Dr Richard A. Deyo and colleagues of Oregon ...

Cleveland Clinic research finds no benefit over placebo in ASSURE trial

2013-09-03
Monday, Sept. 3, 2013, Cleveland: Patients with coronary artery disease and low levels of "good cholesterol – or high-density lipoprotein (HDL) – who were treated with a drug designed to increase HDL levels and reduce coronary plaque build-up, experienced no better results than those treated with placebo, according to research conducted by the Cleveland Clinic Coordinating Center for Clinical Research (C5Research). The drug, RVX-208, induces the production of apolipoprotein A1 (apoA1), a major protein in HDL. Prior research has shown that higher levels of HDL are associated ...

An easier way to control genes

2013-09-03
CAMBRIDGE, MA -- MIT researchers have shown that they can turn genes on or off inside yeast and human cells by controlling when DNA is copied into messenger RNA — an advance that could allow scientists to better understand the function of those genes. The technique could also make it easier to engineer cells that can monitor their environment, produce a drug or detect disease, says Timothy Lu, an assistant professor of electrical engineering and computer science and biological engineering and the senior author of a paper describing the new approach in the journal ACS ...

Young people at higher risk for stroke

2013-09-03
MAYWOOD, Il. -- Fifteen percent of the most common type of strokes occur in adolescents and young adults, and more young people are showing risk factors for such strokes, according to a report in the journal Neurology. Neurologist Jose Biller of Loyola University Medical Center is a co-author of the report, a consensus statement developed by the American Academy of Neurology. Between 532,000 and 852,000 persons ages 18 to 44 in the United States have had a stroke. U.S. hospital discharges for stroke among persons ages 15 to 44 increased 23-to-53 percent between 1995-1996 ...

Medicaid pays for nearly half of all births in the United States

2013-09-03
WASHINGTON, DC -- Medicaid paid for nearly half of the 3.8 million births in the United States in 2010 -- an amount that has been rising over time, according to a report out today. The study, published in the September 2013 issue of the peer-reviewed journal Women's Health Issues, offers the most comprehensive information to date on Medicaid financing of births in each of the 50 states and nationally. The new data will help researchers gauge the impact of health reform on maternal and child health, the authors say. Under the Affordable Care Act (ACA), some states are ...

Body weight influences both the physical and mental quality of life

2013-09-03
Scientists from the Institute of Health Economics and Health Care Management (IGM) and from the Institute of Epidemiology II (EPI II) discovered that weight gain leads to deterioration in physical health. Female study participants, however, experienced improved mental quality of life as their weight increased, a result that was observed even in women who were already overweight when the study began. For this study, Professor Dr Rolf Holle, Michael Laxy and their team evaluated data from the population-based longitudinal KORA study on the association between body weight ...
