"Filmmaker Neels Castillon was on a commercial shoot a few days ago, waiting to catch a helicopter flying into a sunset, when suddenly tens of thousands of starlings unexpectedly swarmed the sky in an enormous dance known as a murmuration. With his director of photography, Mathias Touzeris, the two filmed for several minutes capturing some pretty magnificent footage. You might recall a similar murmuration video from last year shot extremely up close and personal using a camera phone that went viral. How do thousands of birds simultaneously make such dramatic changes in their flight patterns? After tons of research, scientists still aren’t sure."
When falling onto another liquid layer, water droplets typically bounce then coalesce. If the surface is vibrating, however, the droplets will continue bouncing.
"Hundreds of large spirals have been discovered on Mars, and scientists think the coiled features are evidence of a type of lava flow never before seen on the red planet.
If so, the spirals would suggest that volcanoes—not ice floes, as other experts believe—shaped an unusual area near the red planet's equator.
Athabasca Valles is a region of flow channels and valleys covered with terrain plates, structures that show clear evidence of something fracturing and drifting across the planet's surface million years of years ago."
"Plants may be able to respond to sounds and even make clicking noises to communicate with each other, according to new research.
If initial results can be confirmed and replicated, the latest findings could change our understanding of how plants sense their environment and communicate with each other. It would also overturn years of scepticism that plants can 'talk' in this way and give lie to the idea that animals are the only organisms capable of such feats."
"Did this mirage help sink the Titanic? The optical phenomenon called Fata Morgana can make strange shapes or a false wall of water appear above a watery horizon. When conditions are right, light reflecting off of cold water will be bent by an unusual layer of warm air above to arrive at the observer from several different angles.
One hundred years ago... such a Fata Morgana mirage might have obscured real icebergs from the clear view of crew onboard the Titanic. Additional evidence for this distortion hypothesis arises from the nearby vessel SS Californian which reported sightings consistent with Fata Morgana mirages. The above Fata Morgana mirage was taken off the US Pacific coast in 2008."
What to see :
Below you see a rotating array of blue crosses and 3 yellow dots. Now fixate on the centre (watch the flashing green spot). Note that the yellow spots disappear once in a while: singly, in pairs or all three simultaneously. In reality, the 3 yellow spots are continuously present, honest!
What to do :
You can use the slower/faster buttons to change speed. Disappearance persists down to surprisingly low speeds. [If there are no buttons on the right, please update your Flash player.]
You can use the larger/smaller buttons to change size. Disappearance persists up to surprisingly large sizes.
You can use the “back-col” button to change the background colour. The yellow dots disappear into whatever colour the background has.
The ‘defaults’ button at the top restores the standard settings.
