The Bengal tiger population of Suklaphanta Wildlife Reserve in Nepal has declined at least 30 percent, according to camera trap results monitored by World Wildlife Fund (WWF). While once a refuge that boasted among the highest densities of the endangered species in the Eastern Himalayas, the recent survey (April 2008) showed a population of between 6-14 tigers, down from 20-50 tigers in 2005.

Suklaphanta Wildlife Reserve in Nepal is 117 sq miles, less than twice the size of the District of Columbia, and is home to tigers, rhinos and the world's largest flock of Bengal florican (Houbaropsis bengalensis) and swamp deer (Cervus duvauceli). It connects with two tiger reserves in India, Pilbhit and Dudhwa.

New research findings say that if we get smart about diet, even our intelligence can improve.

In an MIT study published in The FASEB Journal, gerbils were given various combinations of three compounds needed for healthy brain membranes: choline, found in eggs; uridine monophosphate (UMP) found in beets; and docosahexaenoic acid (DHA), found in fish oils. Other gerbils were given none of these to serve as a baseline.

They were checked for cognitive changes four weeks later and the scientists found that the gerbils given choline with UMP and/or DHA showed cognitive improvements in tasks thought to be relevant to gerbils, such as navigating mazes. After these tests were concluded, the researchers dissected the mouse brains for a biological cause for the improvement. They found biochemical evidence that there was more than the usual amount of brain synapse activity, which was consistent with behaviors indicating higher intelligence.

LONDON, July 2 /PRNewswire/ --

The In-Depth Report Examining Internet Pharmacies and Life-saving Medicines Purchased Online was Presented Today by the EAASM at the 3rd Annual Pharmaceutical Anti Counterfeiting Conference in London.

The European Alliance for Access to Safe Medicines (EAASM) has today unveiled its comprehensive research report - The Counterfeiting Superhighway. The report reveals that a frightening 62% of medicines purchased online are fake or substandard. These include medicines indicated to treat serious conditions such as cardiovascular and respiratory disease, neurological disorders and mental health conditions.

We all know what happens when cars collide on the freeway or an anvil lands on Wile E. Coyote's head - physics at the macro level is predictable. But what about a single hydrogen atom and a lone molecule of deuterium, the smallest atom and one of the smallest molecules?

When an atom collides with a molecule, traditional wisdom said the atom had to strike one end of the molecule hard to deliver energy to it. People thought a glancing blow from an atom would be useless in terms of energy transfer, but that turns out not to be the case, according to the researchers.

Every atom or molecule, even if it has no charge, has electrostatic forces around it-sort of like the magnetic field of the Earth. Those chemical forces exert a pull on any other atom or molecule within range, trying to form a chemical bond.

More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study reported in the latest issue of European Journal of Cardiovascular Prevention and Rehabilitation.(1) The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis.

The study, performed by Dr Nikolaos Alexopoulos and colleagues at the 1st Cardiology Department, Athens Medical School in Greece, was a randomised trial involving the diameter measurement (dilatation) of the brachial artery of healthy volunteers on three separate occasions - after taking green tea, caffeine, and hot water (for a placebo effect). The measurements were taken at 30, 90 and 120 minutes after consumption. Dilatation of the brachial artery as a result of increased blood flow (following a brief period of ischaemia of the upper limb) is related to endothelial function and is known to be an independent predictor of cardiovascular risk.(2)

Do men who have more sex get less erectile disfunction(ED) or are studies skewed because men with erectile disfunction report having less sex? It's hard to say but the message is clear; have more sex.

Having intercourse more often may also help prevent the development of erectile dysfunction. A study in The American Journal of Medicine reports that researchers have found that men who had intercourse more often were less likely to develop ED.

Analyzing a five-year study of 989 men aged 55 to 75 years from Pirkanmaa, Finland, the investigators observed that men reporting intercourse less than once per week at baseline had twice the incidence of erectile dysfunction compared with those reporting intercourse once per week. Further, the risk of erectile dysfunction was inversely related to the frequency of intercourse.
