Red Wine can distort the results of Testosterone Level in Body

Researchers from the Kingston University, London in January 2013 declared that Red Wine helps in boosting the performance enhancing hormone testosterone in the body of the athletes and players. The researchers also claimed that the beverage would not only help them in winning the trophies, but an athlete under influence of red wine can also cross all the anti-doping tests. A team at the University’s School of Life Sciences led by Professor Declan Naughton in their findings confirmed that there are chances in which, the amount of testosterone excreted by the body is distorted under the influence of Red Wine and can easily skip the drug tests from the Urine Samples. Quercetin is the compound found in red wine that have abilities of blocking the action of enzyme called UGT2B17 partially. UGT2B17 is an enzyme that finds out testosterone in the human body and then signals kidney to excrete it. Testosterone is a natural steroid hormone available in the body of men and women with abilities of increasing the muscle mass, speed up the recovery process and boost stamina to a different level. The research was conducted in test tubes till date and the human trial is yet to be done. The clinical study of its effects on human beings would help in determining the effects of red wine on human being.

2 Billion Year Old Martian Rock Is a Meteorite with 10 Times More Water than Normal

Scientists claimed that the 2- billion year old dark black rock, called Northwest Africa (NWA) 7034 or Black Beauty , which landed into Sahara desert in 2011 is actually new kind of Martian meteorite which contains 10 times excess water than the normal. Black Beauty weighs around 320 g. After studying it intensively for over a year, the team of US scientists finally determined that the meteorite was formed 2.1 billion years ago and that too during the starting of most recent geologic period called Amazonian, on Mars. Programme scientist for the Mars Exploration Programme at NASA headquarters, Washington explained that the age of Black Beauty was important because it is majorly older than the other Martian meteorites. NASA also explained that the meteorite is a perfect match for the outcrops as well as surface rocks which it had studied remotely through their Mars rovers as well as Mars-orbiting satellites. The composition of Black Beauty is much different than previously studied meteorites from Mars. It is composed of cemented remains of basalt, which is a rock that is formed from hastily cooled lava. These remains are mainly pyroxene and feldspar, which most probably are from the volcanic activities. This is an unusual meteorite chemistry which matches the Martian crust that was measured by Mars Odyssey Orbiter as well as Mars Exploration Rovers of Nasa. Around 110 Martian rocks have already been recovered on Earth, primarily in Sahara or Antarctica. The oldest one is from 4.5 billion years ago when Mars was much warmer and wetter. A lot of Martian meteorites are from 1.3 billion years ago and remaining ones are from 600 million years ago. The latest meteorite is Black Beauty which was donated to University of New Mexico by a US citizen who had purchased it from the Moroccan meteorite dealer in 2011.
