An exceptionally well-preserved skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates—including humans—than do modern sharks, as was previously thought.
The new study is based on shark fossil collected in Arkansas, where an ocean basin once was home to a diverse marine ecosystem. The fossilized skull of the new species Ozarcus mapesae was imaged with high-resolution x-rays at the European Synchrotron, letting the scientists “digitally dissect out the cartilage skeleton.”
Asobi by Yasutoki Kariya
“Asobi” was created by art student Yasutoki Kariya for his senior thesis exhibition. Meaning “play,” the installation is comprised of 11 computer-programmed incandescent light bulbs hung from strings. They playfully re-enact Newton’s Cradle, visualizing the transfer of kinetic energy in the form of light. (via Spoon & Tamago)
Cable on Climate Science
Via the Union of Concerned Scientists:
CNN, Fox News, and MSNBC are the most widely watched cable news networks in the U.S. Their coverage of climate change is an influential source of information for the public and policy makers alike.
To gauge how accurately these networks inform their audiences about climate change, UCS analyzed the networks’ climate science coverage in 2013 and found that each network treated climate science very differently.
Fox News was the least accurate; 72 percent of its 2013 climate science-related segments contained misleading statements. CNN was in the middle, with about a third of segments featuring misleading statements. MSNBC was the most accurate, with only eight percent of segments containing misleading statements.

I just need to point out the horrendous disregard of the area principle in this graphic
Tonight’s a great night to look up. Starting at 2AM EDT and peaking from 3am to 4:30, there will be a lunar eclipse visible from all of North America. To make things better, Mars is currently very close to Earth, making it the brightest object in the night sky.
If you’re lucky enough to be viewing tonight’s events from Central Florida, Space-X will be launching a Dragon 9 capsule to the ISS at 4:58PM EDT - adding a little extra something to the sky.
See you in the stars.(viaTumbleOn)
Unfortunately it will be overcast (and eventually rainy) here, but I’m reblogging for people with clearer skies.
If the moon were only 1 pixel on your screen, how big would the rest of the solar system be?
Just click this link, I beg you, and prepare to have your mind blown.
Absolutely amazing. Fantastic work by designer Josh Worth.
