How many of your health supplements are actually snake oil?

‘Recent studies have shown that many vitamins and supplements do little for our health and are a waste of money. This chart will make it abundantly clear how true that is.

In this brilliant chart by David McCandless from 2010, you can see a gorgeous visualization of how many supplements are actually helpful — based on scientific studies — and how many are basically nothing more than snake oil.’ (io9).

Comprehensive search reveals no Internet evidence of time travelers

Abstract: ‘Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive search for specific terms in tweets on Twitter. The second search examined prescient inquiries submitted to a search engine, highlighted by a comprehensive search for specific search terms submitted to a popular astronomy web site. The third search involved a request for a direct Internet communication, either by email or tweet, pre-dating to the time of the inquiry. Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered. Although these negative results do not disprove time travel, given the great reach of the Internet, this search is perhaps the most comprehensive to date.’ (arxiv.org).

NY Times: Clemency for Edward Snowden

Edward Snowden

“When someone reveals that government officials have routinely and deliberately broken the law, that person should not face life in prison at the hands of the same government. That’s why Rick Ledgett, who leads the N.S.A.’s task force on the Snowden leaks, recently told CBS News that he would consider amnesty if Mr. Snowden would stop any additional leaks. And it’s why President Obama should tell his aides to begin finding a way to end Mr. Snowden’s vilification and give him an incentive to return home.” (NYTimes editorial).

Andromeda next to the Moon

‘This is how the Great Spiral Galaxy of Andromeda would look in the sky if it were bright enough. Sadly, its light is too faint. But imagine seeing that every night. Would you get tired of it? I know I wouldn’t.’ (Gizmodo)
