VIDEO: THE JAW-DROPPING BEAD-CHAIN EXPERIMENT


New Picture 310
This is the bead-chain experiment. It's about to melt your brain.
By Robert T. Gonzalez,
io9, 27 June 2013.

Inside this beaker is a 50-meter-long string of 8,000 beads. Watch what happens when you toss one end of the string out of the beaker. Prepare yourself - this is pretty wild.

As you've no doubt noticed, the result is a levitating, single-file stream of beads that buckles, loops and coils in a self-propelled bid to escape its container. It's mesmerizing. In the video, the folks at Earth Unplugged meet up with BBC's Steve Mould to explore the secret to these self-siphoning beads (aka "Newton's Beads"), with the help of some super slow-motion footage.

Mould explains at around the 2-minute mark:

This is the bead-chain experiment. It's about to melt your brain.
Look at it as a sort of tug-of-war. You can see the outer chain is going to be travelling really quickly as it falls, which means the inner chain is going to be travelling really quickly, as well. And if you've got something traveling really quickly, it's got momentum... So you've got the inner chain traveling up, but it wants to change so it's traveling down, but it can't do that in an instant, because that would require infinite force.
Instead what it does is it changes direction slowly over the course of a loop, so that's why it almost has to be a loop, because it needs that time and it needs that space to change directions.
So why do you get different loops and waves and coils? Watch the video below to find out.

Live Science, 28 June 2013.

1. Cave art

New Picture 299

A team of scientists has uncovered a series of engravings and drawings strategically placed in open air and within caves by prehistoric groups of Native American settlers that depict their cosmological understanding of the world around them.


2. Imported tortoise

Two millennia ago, millions of giant tortoises roamed Madagascar, an island nation off the southeastern coast of Africa that is rich in species found nowhere else on Earth.

Those tortoises kept Madagascar's unique ecosystem in check by munching on low-lying foliage, trampling vegetation and dispersing large seeds from native trees like the baobab.


3. Mini Neptunes

New Picture 301

Astronomers using the planet-hunting Kepler spacecraft have found two planets circling different stars in the violent environment of an ancient open star cluster called NGC 6811 located about 3,300 light-years from Earth. Until now, four of the more than 850 planets known outside the solar system were spotted in clusters.


4. Amazing Sea Life

New Picture 302

What lurks in the deep water off the most remote inhabited island in the world? This past month, a team of researchers trekked to Tristan da Cunha, an island in the middle of the South Atlantic Ocean, to find out.


5. Hardy mountain ranges

New Picture 303

Landslides, or the lack thereof, may help mountain ranges remain far longer than previously thought, new research suggests.


6. Nuclear pasta!

New Picture 304

A rare state of matter dubbed "nuclear pasta" appears to exist only inside ultra-dense objects called neutron stars, astronomers say.


7. Bizarre ancient creature

New Picture 305

A new fossilized, cigar-shaped creature that lived about 520 million years ago has been unearthed in Morocco.

The new-found species, Helicocystis moroccoensis, has "characteristics that place it as the most primitive echinoderm that has fivefold symmetry," said study co-author Andrew Smith, a palaeontologist at the Natural History Museum in London, referring to the group of animals that includes starfish and sea urchins.


8. Crazy ants swarm in electronics

New Picture 306

Exterminator Mike Matthews got the call because the home's air-conditioning unit had short-circuited. Why an exterminator for a problem with an appliance? Because of the crazy ants.


9. Burrow buddies

New Picture 307

Scientists have discovered a burrow in South Africa where two unlikely creatures shared a home before being entombed by a flash flood 250 million years ago.

The strange bedfellows were a beat-up young amphibian seeking shelter and a sleeping cynodont, considered a distant ancestor of mammals, researchers say.


10. Research as Art awards

New Picture 308

Typically, you have to crack open the candy shell of a Kinder Surprise egg to find out what kind of toy surprise is tucked inside - that is, unless you have an X-ray micro-computed tomography scanner and a 3D printer.


11. Cryptobiotic soils

New Picture 309

Climate change may transform the community of microbes that forms the crucial top layer of soil, known as a biocrust, in deserts throughout the United States, new research suggests.

8 UNIQUE UFO-SHAPED BUILDINGS


New Picture 139
8 Unique UFO Shaped Buildings
By
The World's Biggests, 29 June 2013.

We have collected some earthly buildings that are shaped like UFO by inspiration.

1. The Flying Saucer House - Chattanooga, Tennessee, USA

New Picture 140

New Picture 141

New Picture 142

This home was built by the late Curtis W. King in 1970, around the time the original Star Trek series ended. It sits on a road leading to Chattanooga's Signal Mountain and features a retractable staircase, like any good UFO should. The three-bedroom, two-bath house was sold in 2008 for US$130,900, after Cleveland, Tennessee's Crye-Leike Auctions posted it for sale on eBay. [More (include videos)]

2. The Circus - Astana, Kazakhstan

New Picture 143

In the late 2005 Astana was the landing site of a UFO in the shape of a huge “flying saucer”. But soon it became clear that it was not a visit of an extraterrestrial civilization but the new capital circus - the Astana Circus. Thanks to its space-like architecture, the building stands out against the urban background. The building is adjoined by the hotel complex, the administration premises, the arena, pens and other circus related building.

New Picture 144

New Picture 145

The circus can seat 2,000 spectators. In the centre there is a classic 13-m arena, which is equipped with modern machinery for the different acts: flights, ice shows, arena, etc.

3. Sanzhi UFO houses - New Taipei City, Taiwan

New Picture 146

The Sanzhi UFO houses, also known as the Sanzhi pod houses or Sanzhi Pod City, were a set of abandoned pod-shaped buildings in Sanzhi District, New Taipei City, Taiwan.

New Picture 147

The UFO houses were constructed beginning in 1978. They were intended as a vacation resort in a part of the northern coast adjacent to Tamsui, and were marketed towards U.S. military officers coming from their East Asian postings. However, the project was abandoned in 1980 due to investment losses and several car accident deaths during construction, which is said to have been caused by the unfortuitous act of bisecting the Chinese dragon sculpture located near the resort gates for widening the road to the buildings. Other stories indicated that the site was the former burial ground for Dutch soldiers.

New Picture 148

The pod-like buildings became a minor tourist attraction due in part to their unusual architecture. The structures have since been subject of a film, used as a location by MTV for cinematography, photographed by people, and become a subject in online discussions, described as a ghost town or "ruins of the future."

New Picture 149

As of 2010, all UFO houses have been demolished and the site is in the process of being converted to a commercial seaside resort and water-park. [Videos]

4. Pensacola Beach’s Spaceship House - Florida, USA

The Universum Bremen opened in September 2000 near to the University of Bremen, Germany. Covering over 4,000 m² the exhibition contains exhibits related to one of the three topics: mankind, earth and the cosmos. The science centre building, with its 40,000 stainless steel scales, resembles a mixture between a whale and mussel. It was designed by the Bremen architect Thomas Klumpp. [Universum Bremen official website] [Video]

6. Chemosphere House - Los Angeles, California, USA

New Picture 156

The Chemosphere, designed by American architect John Lautner in 1960, is an innovative Modernist octagon house in Los Angeles, California.

New Picture 157

The building stands on the San Fernando Valley side of the Hollywood Hills, just off of Mulholland Drive. It is a one story octagon with around 2200 square feet (200m2) of living space. Most distinctively, the house is perched atop a 5-foot-wide concrete pole nearly thirty feet high.

New Picture 158

This innovative design was Lautner's solution to a site that, with a slope of 45 degrees, was thought to be practically unbuildable. Because of a concrete pedestal, almost 20 feet (6.1 m) in diameter, buried under the earth and supporting the post, the house has survived earthquakes and heavy rains. The house is reached by a funicular. Chemosphere is bisected by a central, exposed brick wall with a fireplace, abutted by subdued seating, in the middle. [Video]

7. The Buzludzha Monument - Bulgaria
