Ten-year-old Jani, whose last name isn’t being shared at the request of his parents, uncovered a way to delete any given comment on Instagram, the photo-sharing company that Facebook bought for $1 billion in 2012 — and which Jani, so to speak, pwned. This video explains how those plastic bits in face washes, scrubs, and toothpastes can hurt ecosystems By now, most of us know that if we want our consciences to be as squeaky clean as our faces, we have to ditch our most beloved scrubbing products. While microbeads — the tiny plastic bits most commonly found in face washes, scrubs, and toothpastes — might do great things for your pores, they could also quietly wreak havoc on the environment by steadily streaming into the Great Lakes and oceans. Couldn’t care less about fish? Get this: Through the magic of the food chain, these little plastic beads actually carry the potential to come back around and screw with human health.
11 of humanity's worst ever inventions Nuclear weapons, reality television and Donald Trump are things that we can probably all agree should never have set foot on planet Earth. But what about some of the more tragic human inventions? The good people over at Reddit decided to compile a list of some of humanity's less-than-stellar inventing moments. Here are some of the best/worst... More evidence of Roundup's link to kidney, liver damage ShareThis Scientists report worrisome changes to liver and kidney genes in rats, adding to evidence that a popular herbicide may be toxic August 28, 2015 By Brian Bienkowski Environmental Health News Long-term exposure to tiny amounts of Roundup—thousands of times lower than what is permitted in U.S. drinking water—may lead to serious problems in the liver and kidneys, according to a new study. The study looked at the function of genes in these organs and bolsters a controversial 2012 study that found rats exposed to small amounts of the herbicide Roundup in their drinking water had liver and kidney damage.
Value at risk VaR redirects here. For the statistical technique VAR, see Vector autoregression. For the statistic denoted Var or var, see Variance. The 5% Value at Risk of a hypothetical profit-and-loss probability density function For example, if a portfolio of stocks has a one-day 5% VaR of $1 million, there is a 0.05 probability that the portfolio will fall in value by more than $1 million over a one day period if there is no trading. Informally, a loss of $1 million or more on this portfolio is expected on 1 day out of 20 days (because of 5% probability).

Scott Kelly, who returned from the International Space Station in March, has also commented on the possible health issues he faces in the future as a result of the trip. He said: “During my time in orbit, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained my heart.”
The optical illusion that shows you can't believe what you see Paul Anthony Jones of Haggard Hawks has put together a video that explains a weird linguistic phenomenon known as the McGurk Effect. First Paul asks that the viewer watches him read out "four" words, after which his glamorous assistant Anthony writes down what he thinks Paul said. Anthony comes up with four different words, but Paul reveals that actually No.1 and No.4 were the same. How the Clouds Got Their Names By Maria Popova “Clouds are thoughts without words,” the poet Mark Strand wrote in his breathtaking celebration of the skies. And yet clouds are in dynamic dialogue with our thoughts beyond the realm of the poetic — psychologists have demonstrated that cloudy days help us think more clearly. Since our words give shape to our thoughts, it wasn’t until a young amateur meteorologist named and classified the clouds in 1803 that we began to read the skies and glean meaning from their feathery motions. In this animated primer from TED-Ed, Richard Hamblyn, author of The Invention of Clouds: How an Amateur Meteorologist Forged the Language of the Skies (public library) — the same scintillating book that traced how Goethe shaped the destiny of clouds — tells the story of how the clouds got their names, forever changing our understanding of that most inescapable earthly companion, the weather.
This awesome periodic table tells you how to actually use all those elements Thanks to high school, we’ve all got a pretty good idea about what’s on the periodic table. But whether you’re looking at something common like calcium, iron, and carbon, or something more obscure like krypton and antimony, how well do you know their functions? Could you name just one practical application for vanadium or ruthenium? Lucky for us, Keith Enevoldsen from elements.wlonk.com has come up with this awesome periodic table that gives you at least one example for every single element (except for those weird superheavy elements that don’t actually exist in nature). There’s thulium for laser eye surgery, cerium for lighter flints, and krypton for flashlights.
Kitchen gadgets review: Food Sniffer – ‘It smells fishy to me’ What? The Food Sniffer (£105, myfoodsniffer.com): organic chemical sensors housed in a plastic baton. Detects molecular decomposition in meat and fish. How a Quick Glimpse of Nature Can Make You More Productive A nice walk through a city park can do wonders for a work-weary brain, reducing mental fatigue and improving attention. But if you're trapped on the high floors of an office tower all day, you can't exactly break for a long stroll and a picnic. Well, fear not. If you have a view of a nearby green space, like say a green roof, and even just a minute to spare, you can reap some of the same refreshing benefits of urban nature. That's the upshot of a new paper from an Australia-based research team set for publication in the Journal of Environmental Psychology. Their work has found that even taking just 40 seconds to focus on a view of nature can boost "multiple networks of attention"—sharpening your mind to handle the next task dealt by the work day.

UK supermarkets dupe shoppers out of hundreds of millions, says Which? The competition regulator is to scrutinise allegations that UK supermarkets have duped shoppers out of hundreds of millions of pounds through misleading pricing tactics. Which? has lodged the first ever super-complaint against the grocery sector after compiling a dossier of “dodgy multi-buys, shrinking products and baffling sales offers” and sending it to the Competition and Markets Authority. The consumer group claims supermarkets are pushing illusory savings and fooling shoppers into choosing products they might not have bought if they knew the full facts.
“Chaque jour, les Américains sont bombardés de centaines de messages qui suggèrent qu’une vie bonne s’obtient en achetant des biens matériels…” Dans une vidéo, l’organisation The Center for a New American Dream explique que l’accumulation de possessions ne conduit pas bonheur. Au contraire. Les recherches scientifiques démontreraient que plus les personnes valorisent les valeurs matérielles, moins elles sont heureuses et satisfaites de leur vie. Elles seraient même davantage sujettes à la dépression et à l’anxiété… by miamiwa Mar 24
