Snow leopard diet determined by DNA analysis of fecal samples
2012-03-01
(Press-News.org) Knowledge about animal diet can inform conservation strategy, but this information can be difficult to gather. A new DNA-based method, which analyzes genetic material from feces, could be a useful tool, and researchers have shown its utility to characterize the diet of snow leopards in Mongolia.
The full results are reported Feb. 29 in the open access journal PLoS ONE.
Analysis of DNA from 81 fecal samples showed that the leopards ate mostly Siberian ibex, followed by domestic goats and wild sheep. Most of the animals eaten were wild (79 %), with a relatively low proportion of domestic livestock (19.7 %). The authors, led by Pierre Taberlet of Centre National de la Recherche Scientifique in France, write that the results help further the understanding of snow leopard feeding, which can help address related conservation and management issues.

Millions of years after its extinction, Triceratops is inciting controversy about how to classify the ancient animals. New analysis, published Feb. 29 in the open access journal PLoS ONE, suggests that the specimens in question should be classified into two separate groups, Triceratops and Torosaurus, and are not individuals of different ages from the same genus, as others have proposed.
The researchers, led by Nicholas Longrich of Yale University, performed detailed morphological and computational analysis of 35 specimens and found evidence that Triceratops and Torosaurus ...

"We used a trick called earthshine observation to look at the Earth as if it were an exoplanet," says Michael Sterzik (ESO), lead author of the paper [1]. "The Sun shines on the Earth and this light is reflected back to the surface of the Moon. The lunar surface acts as a giant mirror and reflects the Earth's light back to us — and this is what we have observed with the VLT."
The astronomers analyse the faint earthshine light to look for indicators, such as certain combinations of gases in the Earth's atmosphere [2], that are the telltale signs of organic life. This method ...

A repression of gene activity in the brain appears to be an early event affecting people with Alzheimer's disease, researchers funded by the National Institutes of Health have found. In mouse models of Alzheimer's disease, this epigenetic blockade and its effects on memory were treatable.
"These findings provide a glimpse of the brain shutting down the ability to form new memories gene by gene in Alzheimer's disease, and offer hope that we may be able to counteract this process," said Roderick Corriveau, Ph.D., a program director at NIH's National Institute of Neurological ...

Some women considering breast augmentation worry that, after having this procedure, styles will change and they will, of a sudden, be out of fashion. It is important to remember that fashions do change. Every year there are new clothing options, often in flattering shapes and colors. What is more likely is that smaller, undefined breasts actually inhibit you form wearing the latest fashions and may completely eliminate many clothing options.
Style and fashion are not the same thing. Breast augmentation isn't about fashion, it's about style; your style to be specific. ...

In a mouse model of Alzheimer's disease, memory problems stem from an overactive enzyme that shuts off genes related to neuron communication, a new study says.
When researchers genetically blocked the enzyme, called HDAC2, they 'reawakened' some of the neurons and restored the animals' cognitive function. The results, published February 29, 2012, in the journal Nature, suggest that drugs that inhibit this particular enzyme would make good treatments for some of the most devastating effects of the incurable neurodegenerative disease.

Victims of truck accidents often find themselves mired in a frustrating and complex legal process when trying to seek compensation.
Part of this has to do with the number of parties that may be held accountable in a truck accident. The driver, the trucking company, the personnel who loaded the trailer, and even truck part manufacturers can be held responsible for damages in a truck accident depending on the circumstances.
When you hire a truck accident attorney, one of the first things he or she will look for is potential violations of federal trucking laws. The Federal ...

Urgent action is needed to reduce the high concentrations of dangerous air pollutants in Europe, according to experts writing in the European Respiratory Journal today (1 March 2012).
The European Respiratory Society's Environment and Health Committee are urging policymakers in Europe to introduce changes that will ensure the air that we breathe is safe and clean.
The call to action comes ahead of the upcoming review of air quality legislation in the European Union (EU) before the 2013 Year of Air. In the editorial, the ERS committee argues that any new legislation ...

BOSTON, MA—Very recently, researchers discovered an important population of immune cells called memory T cells living in parts of the body that are in contact with the environment (e.g., skin, lung, GI tract). How these "resident" memory T cells are generated was unknown, and their importance with regard to how our immune system remembers infection and how it prevents against re-infection is being studied intensively.
Now, a study by a Brigham and Women's Hospital (BWH) research team led by Xiaodong Jiang, PhD, research scientist and Thomas S. Kupper, MD, Chair of ...

(Cambridge, Mass.) -- More than 60 years ago, scientists discovered the underlying cause of sickle cell disease: People with the disorder produce crescent-shaped red blood cells that clog capillaries instead of flowing smoothly, like ordinary, disc-shaped red blood cells do. This can cause severe pain, major organ damage and a significantly shortened lifespan.
Researchers later found that the disease results from a single mutation in the hemoglobin protein, and realized that the sickle shape — seen more often in people from tropical climates — is actually an evolutionary ...
