SALT LAKE CITY, March 23, 2010 – Utah's red rocks – world-famous attractions at numerous national parks, monuments and state parks – have yielded a rare skeleton of a new species of plant-eating dinosaur that lived 185 million years ago and may have been buried alive by a collapsing sand dune. The discovery confirms the widespread success of sauropodomorph dinosaurs during the Early Jurassic Period.

Women whose diets are rich in foods containing Omega-3 oils might be less likely to develop endometriosis, while those whose diets are heavily laden with trans fats might be more likely to develop the debilitating condition, new research published today (Wednesday 24 March) suggests.
Hair dye and smoking both increase the risk of progressive liver disease, suggests research involving around 5000 people published in the journal Gut.
Primary biliary cirrhosis (PBC), which is an early form of liver cirrhosis, is a long term progressive autoimmune disease, in which environmental factors are thought to play a part.
It causes the liver's plumbing system of bile ducts to become inflamed, scarred, and blocked, leading to extensive tissue damage and irreversible, and ultimately fatal, liver cirrhosis.
Curcumin, one of the principal components of the Indian spice turmeric, seems to delay the liver damage that eventually causes cirrhosis, suggests preliminary experimental research in the journal Gut.
Curcumin, which gives turmeric its bright yellow pigment, has long been used in Indian Ayurvedic medicine to treat a wide range of gastrointestinal disorders.
Previous research has indicated that it has anti-inflammatory and antioxidant properties which may be helpful in combating disease.
A study from Denmark published on bmj.com today finds no effect of the Danish screening programme on breast cancer deaths.
Similar results have been seen in other countries, including the UK, leading the authors to question whether screening has delivered the promised effect on breast cancer mortality.
New guidance to improve the reporting of trial findings is published simultaneously today (24 March 2010) by the BMJ and eight other leading journals around the world.
Full and transparent reporting of trials is crucial to ensure that decisions about health care are based on the best available evidence.
Following months of gruelling tests and trials, scientists now reveal the World's strongest insect to be a species of dung beetle called Onthophagus taurus.
In an experiment to find out why animals vary so much in strength and endurance, Dr Rob Knell from Queen Mary, University of London and Professor Leigh Simmons from the University of Western Australia found the strongest beetle could pull an astonishing 1,141 times its own body weight - the equivalent of a 70kg person lifting 80 tonnes (the same as six full double-decker buses).
Taking arginine supplements can improve the cycling ability of over-50s. Researchers writing in BioMed Central's Journal of the International Society of Sports Nutrition tested a combination of the amino acid and an antioxidant in sixteen cyclists, finding that it enhanced their anaerobic threshold – the amount of work done before lactic acid begins to accumulate in the blood.
In the coming decades, climate change is set to produce worldwide changes in the living conditions for plants, whereby major regional differences may be expected to occur. Thus today´s cool, moist regions could in future provide habitats for additional species, and in arid and hot regions the climatic prerequisites for a high degree of plant diversity will deteriorate. This is the conclusion reached in a new study by scientists at the Universities of Bonn, Göttingen and Yale, and published in the Proceedings of the Royal Society London.
SAN FRANCISCO, March 23, 2010 — The plant that gave the world tequila contains a substance that seems ideal for use in a new genre of processed foods -- so-called "functional foods" -- with health benefits over and above serving as a source of nutrients, scientists reported here today at the 239th National Meeting of the American Chemical Society (ACS). Foods spiked with "fructans" from the agave plant may help protect against osteoporosis by boosting the body's absorption of calcium and could have other health benefits, they said.

New research finds that there is an inverse association between the level of supine (lying face up) systolic blood pressure measured on admission to an intensive care unit for acute chest pain and risk of death at one year, with those patients having high systolic blood pressure having a better prognosis after a year, according to a study in the March 24/31 issue of JAMA.
Long-term complications after procedures to close coronary artery fistulas are particularly prevalent among those whose abnormal connections to the heart result in drainage into the coronary sinus, according to a study published in Circulation: Cardiovascular Interventions, a journal of the American Heart Association.
ROCHESTER, Minn. -- An international study of nearly 100 clinical trials that were stopped early due to positive treatment effects has found that many of those effects were exaggerated. The authors of the study -- published in the current issue of the Journal of the American Medical Association -- recommend that researchers resist pressures to end clinical trials early and continue trials for longer periods before even considering premature termination.
HIV-infected patients are at a markedly increased risk for community acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) infections according to a new study by researchers at John H. Stroger, Jr. Hospital of Cook County and Rush University Medical Center.
The study, published in the April 1 issue of the journal Clinical Infectious Diseases, found the incidence of CA-MRSA in the Chicago area was six-fold higher among HIV-infected patients than it was among HIV-negative patients.
