    Readers dispute starfishes' water-swirling abilities

    Doomsday preppers

    Dinosaurs and other creatures were largely wiped out 66 million years ago from an asteroid impact, volcanic eruptions or maybe a mix of the two, Thomas Sumner reported in “Devastation detectives” (SN: 2/4/17, p. 16), in the Science News special report “Dino Doomsday.”

    Online reader Mike van Horn wondered if the timing of the v­olcanic eruptions, which happened for h­...

    Coconut crab pinches like a lion, eats like a dumpster diver

    A big coconut crab snaps its outsized left claw as hard as a lion can bite, new measurements suggest. So what does a land crab the size of a small house cat do with all that pinch power?

    For starters, it protests having its claw-force measured, says Shin-ichiro Oka of the Okinawa Churashima Foundation in Motobu, Japan. “The coconut crab is very shy,” he says. It doesn’t attack people...

    Dinosaurs may have used color as camouflage

    The stories of dinosaurs’ lives may be written in fossilized pigments, but scientists are still wrangling over how to read them.

    In September, paleontologists deduced a dinosaur’s habitat from remnants of melanosomes, pigment structures in the skin. Psittacosaurus, a speckled dinosaur about the size of a golden retriever, had a camouflaging pattern that may have helped it hide in forests...

    A new ‘Einstein’ equation suggests wormholes hold key to quantum gravity

    There’s a new equation floating around the world of physics these days that would make Einstein proud.

    It’s pretty easy to remember: ER=EPR.

    You might suspect that to make this equation work, P must be equal to 1. But the symbols in this equation stand not for numbers, but for names. E, you probably guessed, stands for Einstein. R and P are initials — for collaborators on two of...

    Sometimes busting myths can backfire

    It was the mic drop heard ’round the Internet.

    On January 25, rapper B.o.B (Bobby Ray Simmons) sent out a series of statements on Twitter stating why he thinks the Earth is flat.

    Entanglement is spooky, but not action at a distance

    First of two (entangled) parts. Read part two. 

    A couple of weeks before last Halloween, physicists in the Netherlands treated the physics world with experimental proof of what Einstein called “spooky action at a distance.”

    It’s not the first time experiments have demonstrated the spooky phenomenon, known as quantum entanglement. But this particular experiment closed some loopholes...

    Quantum spookiness survives its toughest tests

    Second of two (entangled) parts. Read part one. 

    Until his death in 1955, Albert Einstein hoped that someday science would do away with what he called spooky action at a distance.

    His concern was quantum entanglement. Two entangled particles, even after traveling very far from one another, share a mysterious quantum connection. Measuring one tells you instantly what the outcome...

    Water bears’ genetic borrowing questioned

    Water bears may not be champion gene borrowers after all, a new analysis suggests.

    Researchers in Scotland and colleagues say foreign genes may account for less than 1 percent of the genome of the famously hardy critters, technically known as tardigrades (Hypsibius dujardini). That result, reported in a paper posted online December 1 at BioRxiv.org, directly contradicts a previous study ...

    Adorable birds tap dance their way into the heart of a mate

    View the video

    Blue-capped cordon-bleu songbirds (Uraeginthus cyanocephalus) know how to bust a move like Fred Astaire. The birds belt out some dulcet tones, stick some nesting material in their beak, bob up and down — and rhythmically tap their feet.

    Researchers summarize the first evidence of such “tap dancing” in this socially monogamous species November 19 in Scientific Reports...

    Using general relativity to magnify the cosmos

    One of the most powerful known magnifying lenses isn’t found on Earth. The lens is built from stars, gas and dark matter and lies about 4 billion light-years away. As astronomers peer through it, they are finding the seeds of galaxies that were scattered around the universe more than 13 billion years ago.

    The lens is known as Abell 2744, a cosmic pileup where four groups of galaxies are...
