Tibetans Underwent Fastest Evolution Seen in Humans

“Life at high altitudes forced ancient Tibetans to undergo the fastest evolution ever seen in humans, according to a new study. The most rapid genetic change showed up in the EPAS1 gene, which helps regulate the body's response to a low-oxygen environment. One version, called an allele, of the EPAS1 gene changed in frequency from showing up in 9 percent of the Han Chinese to 87 percent of Tibetans. Such genetic changes suggest Tibetan ancestors split off from the Han Chinese population about 2,750 years ago, researchers say. But only those most evolutionarily suited for life at high altitudes survived when they moved to the Tibetan Plateau. “It took only a few hundred generations to change the allele frequency, which can only happen if a lot of people have died,” said Rasmus Nielsen, an evolutionary biologist at the University of California at Berkeley. “In that sense, it must have had a strong effect on fitness.” The Tibetan example of human evolution beats the previous record holders in northern Europe, who evolved lactose tolerance to digest the milk sugar lactose over the course of about 7,500 years.” More at link! http://www.livescience.com/health/Tibetans-underwent-fastest-evolution-seen-in-h… added by: DeliaTheArtist

Big Pharma-Backed Marijuana Spray As Medicine

British health regulators have approved the sale and marketing of Sativex, an oral spray consisting of natural cannabis extracts (primarily the plant cannabinoids THC and cannabidiol aka CBD) as a treatment for symptoms of multiple sclerosis. (MS) The spray, which has been legally available to patients in Canada since 2005, went on sale in Britain on Monday. The drug will be marketed in the United Kingdom by the Bayer Corporation which estimates that Sativex will cost the country’s state-run National Health Service roughly

Study on Mobile Phone linked to Brain Cancer

In our modern times wherein it is a necessity to always be in touch with the world, one of the ever-present tools that we have is our reliable mobile phones or cell phones. No matter where you are in the world it is likely that you have access to this piece of device. However, there are some concerns from ordinary citizens even up to the scientific community if this wonderful equipment could cause negative effects to one’s health, specifically cancer. Recently, the World Health Organization released a substantial amount of funding for wide-scale studies concerning the long-term effect of regular use of mobile phone. Even before the initial phase of the study, the proponents were already faced by several boundaries, particularly with the time needed for a cancer cell to develop, since it normally takes years or even decade to form. The scientific community is still skeptic but the minute evidence that there is an increased risk of acquiring cancer with the frequent use of mobile phone compel them to go deep. It is very well-known for a fact that mobile phone emits radio waves but there is still no proof that this could affect the body of a healthy individual. Until the scientific community comes up with a conclusive result, it is always important to keep in mind that prevention is better than cure. There are tons of hands free devices that would reduce your exposure to these radio waves. – AP Study on Mobile Phone linked to Brain Cancer is a post from: Daily World Buzz Continue reading

Were Russian security services behind the leak of ‘Climategate’ emails?

Suspicions were growing last night that Russian security services were behind the leaking of the notorious British ‘Climategate’ emails which threaten to undermine tomorrow’s Copenhagen global warming summit. An investigation by The Mail on Sunday has discovered that the explosive hacked emails from the University of East Anglia were leaked via a small web server in the formerly closed city of Tomsk in Siberia.
