Do they go to the moon, or are they off to fight battles with goat-riding armies? (Spoiler alert: Those theories are for the birds.) Joe Hanson of It’s Okay to Be Smart investigates bird migration, the seasonal journeys of our feathered friends to warmer climates.

Kokichi Sugihara’s Impossible Rooftop & Folding Ladder Illusions http://thekidshouldseethis.com/post/kokichi-sugiharas-impossible-rooftop-illusion http://thekidshouldseethis.com/post/kokichi-sugiharas-impossible-rooftop-illusion#comments Wed, 26 Nov 2014 09:39:48 +0000 http://thekidshouldseethis.com/?p=13329 File under impossible objects, this is the Impossible Rooftop Illusion or “Anti-Gravity Two Sided Roof” by Meiji University’s Professor Kokichi Sugihara in 2013. Using computer software, Sugihara creates award-winning, perception-bending 3D models that seem to defy geometry. While the structures look impossible from one angle, viewing them from another angle reveals the illusion. Of the computer-designed impossible motions, he writes:

“Computational illusion” is aimed at studying human visual illusions mathematically. If we could reveal how and under what conditions human visual illusions occur, we would be able to numerically express the strength of visual illusions and control the quantity.

Here’s one more, via Nautil.us: Folding Ladder.

Ocean Moon, Ocean World: The water beneath Europa’s icy surface http://thekidshouldseethis.com/post/ocean-moon-ocean-world-the-water-beneath-europas-icy-surface http://thekidshouldseethis.com/post/ocean-moon-ocean-world-the-water-beneath-europas-icy-surface#comments Tue, 25 Nov 2014 20:56:10 +0000 http://thekidshouldseethis.com/?p=13315 Thanks to Earth-bound telescopes and flyby data collected “about the surface, about the interior structure, and about the magnetic field around Europa” by multiple spacecrafts, scientists strongly believe that there’s a liquid ocean of water beneath the Galilean moon‘s icy surface. It’s an amazing possibility, but why is it an important one?

In this video from NASA JPL, Europa: Ocean World, astrobiologist Kevin Hand explains the connections between Earth and Europa, and why we want to know more about what’s below this moon’s crust:

“Where you find the liquid water, you generally find life.”

If that was the end of the story it would already be an incredible feat of nature, but perhaps what’s more incredible is the diversity of growths themselves: lumps, warts, balls, knobs, tubes, cones, disks, and other unexpected shapes. Furry, fuzzy, rough, scaly, brittle, wrinkly, pink, brown, yellow… the descriptions go on and on. There’s even a name for the study of plant galls: cecidology.

Planet Earth in 4K: Time lapse images taken by an orbiting satellite http://thekidshouldseethis.com/post/planet-earth-in-4k-time-lapse-images-taken-by-an-orbiting-satellite http://thekidshouldseethis.com/post/planet-earth-in-4k-time-lapse-images-taken-by-an-orbiting-satellite#comments Thu, 20 Nov 2014 20:40:43 +0000 http://thekidshouldseethis.com/?p=13094 This video truly illustrates why our Earth is called The Blue Marble. Taken every 30 minutes over Indian ocean from May 15th to May 19th, 2011, these images by the geostationary Elektro-L weather satellite have been compiled into an incredibly high resolution time lapse: Planet Earth in 4K resolution.

The animation was edited together by James Tyrwhitt-Drake, who also created a stunning 4K time lapse animation of the sun. From his video notes:

To answer frequently asked questions; why are city lights, the Sun, and other stars not visible? City lights are not visible because they are thousands of times less bright than the reflection of sunlight off the Earth. If the camera was sensitive enough to detect city lights, the Earth would be overexposed. The Sun is not visible due to mechanisms used to protect the camera CCD from direct exposure to sunlight. A circular mask on the CCD ensures that only the Earth is visible. This mask can be seen as pixelation on Earth’s horizon. The mask also excludes stars from view, although they would not be bright enough to be visible to this camera.

Related reading: The Overview Effect, “a cognitive shift in awareness reported by some astronauts and cosmonauts during spaceflight, often while viewing the Earth from orbit or from the lunar surface.”

It refers to the experience of seeing firsthand the reality of the Earth in space, which is immediately understood to be a tiny, fragile ball of life, “hanging in the void”, shielded and nourished by a paper-thin atmosphere. From space, astronauts claim, national boundaries vanish, the conflicts that divide people become less important, and the need to create a planetary society with the united will to protect this “pale blue dot” becomes both obvious and imperative.

Wild Inside the National Zoo: Raising Red Panda Cubs Tink & Henry http://thekidshouldseethis.com/post/wild-inside-the-national-zoo-raising-red-panda-cubs-tink-henry http://thekidshouldseethis.com/post/wild-inside-the-national-zoo-raising-red-panda-cubs-tink-henry#comments Thu, 20 Nov 2014 18:39:31 +0000 http://thekidshouldseethis.com/?p=13088 This is the story of Tink and Henry, two of ten red panda babies that were born at the Smithsonian’s National Zoo in 2014. Both cubs had early health problems, prompting zoo keepers to take immediate action: around the clock medical support and hand-rearing. Henry especially struggled, and was on oxygen for a month after he had stopped breathing. Thankfully, with constant care, both cubs are now healthy and thriving.

Native to the cool, temperate forests high in the eastern Himalayas and south-western China, red pandas are tree dwelling mammals that eat a lot of bamboo in addition to fruit, acorns, roots, and eggs. Despite their bamboo-filled diet, name, and adorable eye patches, they are not related to Giant Pandas. From Scientific American:

…it wasn’t until the last ten or fifteen years that scientists settled upon just where red pandas fit on the evolutionary tree of life. It was clear that red pandas were members of the taxonomic “infraorder” Arctoidea, placing them in a group with bears, pinnipeds (seals, sea lions, and walrus), raccoons, and mustelids (weasels, skunks, otters, and badgers). Research published in 2000 in the journal Molecular Phylogenetics and Evolution determined that they were not most closely related to bears or to raccoons as had been previously suggested. Instead, red pandas form their own phylogenetic family, alongside skunks, raccoons, and mustelids. From a genetic perspective, they’re more like the skunks and raccoons you might find in your own backyard than the giant pandas with whom they share habitats.

In 2012, former Cal Berkeley quarterback Joe Ayoob officially broke the Guinness World Record by flying a John Collins designed paper airplane 69.14 meters (226 feet, 10 inches) — that’s 5.95 meters or 19 feet, 6 inches farther than the previous record. Now try to break Ayoob’s record…

More Evidence Birds Can Count: Where’d that other mealworm go? http://thekidshouldseethis.com/post/science-take-how-birds-count http://thekidshouldseethis.com/post/science-take-how-birds-count#comments Wed, 19 Nov 2014 18:07:03 +0000 http://thekidshouldseethis.com/?p=12986 Researchers are eagerly tricking wild New Zealand robins, but it’s FOR SCIENCE! Watch as this box with a sliding trick drawer helps Alexis Garland and Jason Low at Victoria University of Wellington observe the behavior of a robin after it’s offered two mealworms. The experiment was set up like this:

After clearly showing a robin that she was dropping two mealworms in a circular well in the box, Dr. Garland would slide in the drawer. It covered the two worms with an identical-looking circular well containing only one worm.

When the researcher moved away and the robin flew down and lifted off a cover, it would find only one worm. The robins pecked intensely at the box, behavior they didn’t show if they found the two worms they were expecting.

So here’s the big question:

If birds and mammals can count, does this mean some kind of mathematical ability goes back to a common ancestor before the dinosaurs? Or did two separate paths lead to the same abilities?
