The Science Career Ladder doesn’t always take Explainers on a path to Science. In Todd’s story, working at the New York Hall of Science whipped him into shape and boosted his confidence to a level where he will succeed in any career.
"I feel I’ve not only seen the future, but am immersed in the details of these tragic cases…" says Ken Burns about False Conviction, the new iBook we’ve just produced with Jim Dwyer and The Innocence Project. Here’s the trailer.
To celebrate the last day of our “22 Days Of Invention” series, we wanted to give something back to the Tumblrverse. So, we had our friends at Tattly print temporary tattoos of Thomas Edison’s lightbulb patent.
Hit us up with some fan mail if you want one. UPDATE: Thanks for the response! Alas, there are no more tattoos. The fine print says you must be 18 or over and a resident of the U.S. for us to send you one. Additionally, Tumblr didn’t endorse, administer or sponsor these tats, and only the GE social media team will receive participant information.
Elliott Kaufman, photographer, in the NYSCI Library, February 17, 2014. Our library visitors learned to look at the world in a new way; recognizing letters and numbers every where they go!
Elliott engaged our audience with numbers and letters from his books, NUMBERS EVERYWHERE and ALPHABET EVERYWHERE. Who is seven? he asked. He handed them photos of the number 7 that he has found in architecture and other places. Who’s name starts with a B (or C or D)?
This was a different sort of visit than our usual straight forward author visit. He did not read a story or talk about writing children’s books. He engaged the audience in visual fun. They eagerly responded. Thank you Elliot! And thanks to Abbeville Press for making this happen and supporting our promotions.
daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. each piece (click pic for name) is from the great barrier reef. given the complexity of the techniques used, which involve time-lapse and stereoscopic and focus stacked photography, the images take up to ten hours to produce in the lab.
Wow. I thought these were computer-generated protein models or something at first, but these are brilliantly fluorescing corals!!
What might be seeing these stunning fluorescent displays? Coral aren’t known to have any photo-sensitivity (at least past the larval stage), so the obvious candidates are fish, whose eyes would be sensitive to the emitted fluorescent wavelengths.
Do fish like that exist? Earlier this year, researchers at the American Museum of Natural History were photographing their own corals’ fluorescence when they accidentally noticed one of their eels was fluorescing too. No one had noticed because the fluorescence is usually masked in the presence of broad visible light as seen by us land-lubbers.
It turns out that fluorescence in fish is surprisingly common. Water filters out long and medium wavelength light (reds and yellows) as it gets deeper, which is why it’s blue. To compensate for this limited spectral availability, fish have turned to fluorescence as a way to expand the wavelengths of communication and camouflage in their normally azure-monochrome world.
