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.

Watch the video! 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…

In this how-to video, Paper Airplane Guy and world record-breaking paper airplane designer John Collins demonstrates how to make the “Suzanne”.

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?

SciFri: The gigantic dinosaur puppets of Walking With Dinosaurs http://thekidshouldseethis.com/post/scifri-the-gigantic-dinosaur-puppets-of-walking-with-dinosaurs http://thekidshouldseethis.com/post/scifri-the-gigantic-dinosaur-puppets-of-walking-with-dinosaurs#comments Mon, 17 Nov 2014 10:33:04 +0000 http://thekidshouldseethis.com/?p=12866 Go behind-the-scenes of Walking with Dinosaurs: The Arena Spectacular, based on the BBC television series, with Science Friday as they explore the wide variety of high-tech ways that these 20 gigantic dinosaur puppets move around on stage. In the story, time-traveling British biologist Thomas Henry Huxley adventures across 230 million years, beginning in the Triassic period, to see these creatures, and though that premise is fanciful, the dinosaurs are based on animals and evolving dino research to (hopefully) be more realistic.

For inspiration, The Creature Technology Company team pored through scientific and popular science literature to understand, generally, what various dinosaurs might have looked like. They also observed the way large, living animals, such as elephants and giraffes, move.

Constructing the puppets required working “from the inside out…” Autopsy one of the behemoths, and you’ll find architecture somewhat similar to a real animal’s. For starters, the larger puppets have a skeleton made of steel, complete with points of articulation that allow their bodies to move in a way that seems natural.

Cover that with stretchy, styrene bead-filled muscle bags, a lycra skin, and hand-painted details to make them look like biological creatures. When the curtain goes up, a team of drivers, suit performers, and “voodoo puppeteers” help the dinosaurs come alive with a lot of technology. Watch and read more about it at ScienceFriday.com.

Non-Newtonian fluid bouncing in super slow motion (1600fps) http://thekidshouldseethis.com/post/non-newtonian-fluid-bouncing-in-super-slow-motion-1600fps http://thekidshouldseethis.com/post/non-newtonian-fluid-bouncing-in-super-slow-motion-1600fps#comments Thu, 13 Nov 2014 16:58:07 +0000 http://thekidshouldseethis.com/?p=12796 We’ve seen oobleck bouncing on a speaker before, but we’ve never see it in 1600fps super slow motion like this. Watch as The Slow Mo Guys color oobleck red, puddle it into an old speaker, and slow it way, way down.

Oobleck is a Seussian nickname for corn starch and water mixed together to make a Non-Newtonian fluid, a substance like ketchup, custard, toothpaste, paint, blood or shampoo that has qualities of both a liquid and a solid, switching between those states in response to how much pressure is applied to them.

The vibration strength will also make it behave differently. Watch this 2008 video for what it looks like in real time with a smaller, more consistent vibration:

DIY: 1 cup water, 1 to 2 cups cornstarch, and a bit of food coloring (optional). Read more at Scientific American or Wired.
