Researchers from China, Leicester and Oxford have discovered a remarkable fossil which sheds new light on an important group of primitive sea creatures.
The 525-million-year-old fossil belongs to a group of tentacle-bearing creatures which lived inside hard tubes. Previously only the tubes have been seen in detail but this new specimen clearly shows the soft parts of the body including tentacles for feeding.
Research presented today at the European Congress on Osteoporosis & Osteoarthritis by investigators from the UK and Sweden estimates that the economic burden of fragility fractures in five major European countries totals 31 billion Euro, with Germany bearing the highest costs. A majority of the economic burden is shown to be related to the costs incurred during the 1st year after the fracture, while pharmacological prevention and treatment management constitutes only a marginal share of the total economic cost.
A study presented today at the European Congress on Osteoporosis and Osteoarthritis currently taking place in Valencia, Spain has found that the initial quality of life loss following an osteoporotic fracture is substantial, especially with regard to hip and vertebral fractures. The study found differences in quality of life loss between countries after correcting for other explanatory variables.
BUFFALO, N.Y. -- After age 21, problem gambling is considerably more common among U.S. adults than alcohol dependence, even though alcohol dependence has received much more attention, according to researchers at the University at Buffalo's Research Institute on Addictions.
Simulated acupuncture - sometimes referred to as placebo - is just as beneficial as real acupuncture for treating nausea in cancer patients undergoing radiotherapy, according to a study from Karolinska Institutet and Linköping University in Sweden. Patients, who received only standard care including medications for nausea, felt significant more nausea than patients in both the acupuncture groups.
The use of different resources by males and females exacerbates the estimation of population sizes. However, the monitoring of population sizes, particularly for rare and threatened species, is pivotal to quick and effective conservation action. Scientists from the Max Planck Institute for Ornithology in Radolfzell investigated the ecological niches of male and female parti-colored bats (Vespertilio murinus) and found out that the sexes use entirely different foraging grounds.
Diabetes type 2 is caused by insufficient levels of insulin to keep blood glucose under control. Excessive levels of another hormone, glucagon, can also contribute to diabetes type 2 by causing the liver to flood the body with stored glucose. Diabetes type 2 does not arise overnight, but slowly progresses for many years as a condition known as prediabetes. In prediabetes, blood sugar rises to excessive levels after a meal, but is normal or nearly normal after an overnight fast. Researchers are seeking ways to prevent prediabetes from progressing to diabetes.
New evidence has emerged from studies in mice that short telomeres or "caps" at the ends of chromosomes may predispose people to age-related diabetes, according to Johns Hopkins scientists.

Researchers from the Department of Optics of the University of Granada, belonging to the Laboratorio de Ciencias de la Visión y Aplicaciones, have developed a programme for testing alterations in night vision, and the tool required to implement it, which has been named "halometer".
CLEMSON, S.C. — Biomechanics researchers Timothy Higham of Clemson University and Andrew Clark of the College of Charleston conclude that moving quickly in a forward, firm-footed stance across a slippery surface is less likely to lead to a fall than if you move slowly. Approaching a slippery surface slowly hinders the necessary task of shifting the center of mass forward once foot contact is made.
If it bleeds, it leads, or so the old journalistic adage goes. Not necessarily, say researchers from McGill University and the Lady Davis Institute for Medical Research of the Jewish General Hospital. In a first-of-its kind study that analyzes how cancer is portrayed in Canadian newspapers today versus 20 years ago, positivity and hope seem to be winning out.
If you seek America's most diverse, densely packed human population, head for New York's Manhattan, but if it's lichens you fancy instead of people, then Southwestern Florida is your best bet.
Philadelphia, PA, 24 March 2011 - Studies in twin pairs suggest that 40% of the risk for panic disorder is heritable, yet the manner in which genes contribute to the risk for panic disorder is far from clear. To date, variations in a growing number of genes have been implicated in the risk for panic disorder, but the magnitude of the impact of each individual gene is relatively small.
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have developed a new method which enables researchers to label any protein of their choice with any of a wide variety of previously available compounds, in living cells, by introducing a single reactive artificial amino acid. Published today in Angewandte Chemie, the new technique enables researchers to label even rare proteins very precisely for optical imaging and in the future likely also for Magnetic Resonance Imaging (MRI).
Have you been wearing your retainer? It's a question countless parents ask of their children post-braces. Now Case Western Reserve University School of Dental Medicine researchers are getting serious about the question.
"We found little written about the kinds of retainers prescribed and how compliant patients are in using them," said Case Western Reserve's Manish Valiathan, an assistant professor of orthodontics and a member of the American Board of Orthodontics. He notes that there is a dearth of information despite the devices being common in orthodontics practice.
