    You’ve probably been tricked by fake news and don’t know it

    If you spent Thanksgiving trying in vain to convince relatives that the Pope didn’t really endorse Donald Trump or that Hillary Clinton didn’t sell weapons to ISIS, fake news has already weaseled its way into your brain.

    Those “stories” and other falsified news outperformed much of the real news on Facebook before the 2016 U.S. presidential election. And on Twitter, an analysis by...

    Attempt to shame journalists with chocolate study is shameful

    “I Fooled Millions Into Thinking Chocolate Helps Weight Loss. Here's How.”

    That’s the headline on a May 27 article by science journalist John Bohannon that revealed the backstory of a sting operation he conducted earlier this year. Bohannon and a German television reporter teamed up to “demonstrate just how easy it is to turn bad science into the big headlines behind diet fads.” So they...

    Sam Ting tries to expose dark matter's mysteries

    In the near vacuum of outer space, each rare morsel of matter tells a story. A speedy proton may have been propelled by the shock wave of an exploding star. A stray electron may have teetered on the precipice of a black hole, only to be flung away in a powerful jet of searing gas.

    Since 2011, the International Space Station has housed an experiment that aims to decipher those origin...

    Here’s the poop on getting your gut microbiome analyzed

    Guest post by Tina Hesman Saey

    I donated my used toilet paper to science. The act wasn’t a prank or a weird protest; it was an effort to discover what microbes are living in my intestines.

    Those microbes in and on your body include bacteria, which outnumber your own cells 10 to 1. Together with with fungi, archea, viruses and other single-celled organisms, they are known...

    Mama frog’s care includes a gift of poison

    Strawberry poison frogs (Oophaga pumilio) don't create their own poison. The Central American frogs sequester the alkaloid chemicals from the mites, ants and other arthropods they eat and store it in glands on their skin. Predators that ignore the bright red “don't eat me” warning pigmentation get a nasty surprise — a bad taste in their mouth, sickness or even death.

    Tadpoles of a...

    Animal mummies were a message direct to the gods

    Ancient Egyptians killed a lot of animals and turned them into mummies, but the purpose for such sacrifices isn’t always clear. At the highest levels of Egyptian society, people were buried with their mummified pets, presumably because they were beloved animals. Many tombs also included mummified animal meat, such as whole ducks and the forelegs of bulls, probably meant to feed the human...

    Space Eats

    Even an Iron Chef couldn’t master what a food-centric cadre of NASA scientists do every day: Devise tasty, healthy meals for astronauts to take into low-Earth orbit and beyond — perhaps even to Mars.

    Feeding people in space is harder than it sounds. Meals have to contain enough nutrients to keep the human body functioning in near-zero gravity. Slicing, dicing and stir-...

    BP spill: Gulf is primed to heal, but . . .

    Every day, Mother Nature burps another 1,000 barrels of crude into the Gulf of Mexico, along with additional quantities of natural gas. They enter from more than 1,000 widely dispersed natural seeps, deposits that University of Georgia oceanographer Samantha Joye has been studying for 15 years. Normally, these hydrocarbons don’t stick around long because local bacteria have evolved to eat...

    Rapid evolution may be reshaping forest birds’ wings

    PHILADELPHIA — When trees fall in the forest, unheard or not, they may change the shape of bird wings. 

    As logging whittled away at Canada’s vast boreal forest during the past century, bird species that frequent mature woodlands developed somewhat pointier wing tips, says André Desrochers of the Center for Forest Research at Laval University in Québec City.

    During the...

    Moms: One Solution to Tainted Milk

    This morning I read that East Asian chocolates are the latest fallout from the ongoing melamine-tainted-milk crisis. Certain chocolate candies have been testing positive for melamine — even those produced under such name brands as Cadbury and M&Ms. As distressing as that is to inveterate chocolate consumers (like me), the real crisis of course is the health of an estimated 52,000 Chinese...
