Mariana Trench Sound

The Mariana Trench, which lies between Japan to the north and Australia to the south, features depths in excess of 36,000 feet, and is currently the deepest known part of the Earth's oceans. Scientists at OSU's Hatfield Marine Science Center detected a strange booming sound heard in the the deepest part of the ocean, and called i the "Western Pacific Biotwang". The mysterious five-part call lasts between 2.5-3.5 seconds, and includes frequencies as low as 38 hertz. It was recorded using passive acoustic ocean gliders, or instruments that traverse the ocean autonomously, and can dive up to 1,000 meters.

Vantablack S-Vis

This is what a perfect circle looks like when coated with Vantablack S-VIS, a substance made of carbon nanotubes. It's currently the blackest substance known, absorbing up to 99.965% of radiation in the visible spectrum. When light strikes vantablack, instead of bouncing off, it becomes trapped and is continually deflected among the tubes, eventually becoming absorbed and dissipating into heat. The outgassing and particle fallout levels of Vantablack are low. The high levels in similar substances in the past had prevented their commercial usefulness. Vantablack also has greater resistance to mechanical vibration, and has greater thermal stability. Continue reading for more interesting pictures from around the web.

Floating Coffee Table

You could either spend $30,000 on a brand new car, or on the Teles Taxidi floating coffee table, designed by engineers at Siren Design Studios. A pair of rare-earth magnets balanced on top of each other hover 2-inches above its base, suspended by a series of 1,000+ lbs tested Kevlar cord and pulleys. As you can see in the video above, the table goes right back to its original configuration no matter which direction it is pushed.

Floating Gym Paris

River cruises are nothing new, but a floating gym powered by human energy is an entirely different story. Designed to flow down the Seine River, this 20-meter-long Paris Navigating Gym is powered by Technogym's revolutionary ARTIS exercise machines, which harvest power generated by humans. "The Paris Navigating Gym investigates the potential of harnessing human power. It's fascinating to see how the energy generated by a workout at the gym can actually help to propel a boat. It provides one with a tangible experience of what lies behind the often abstract notion of 'electric power'," said Carlo Ratti, founder of Carlo Ratti Associati.

Earth Second Moon


After spending nearly a 100-years in Earth's orbit, NASA has recognized a tiny asteroid - known as "asteroid 2016 HO3" - circling our planet as the new "mini moon." This object measures 120-feet to 300-feet in diameter, and slowly circles the sun as well as the Earth. "The asteroid's loops around Earth drift a little ahead or behind from year to year, but when they drift too far forward or backward, Earth's gravity is just strong enough to reverse the drift and hold onto the asteroid so that it never wanders farther away than about 100 times the distance of the moon. The same effect also prevents the asteroid from approaching much closer than about 38 times the distance of the moon. In effect, this small asteroid is caught in a little dance with Earth," said Paul Chodas, manager of NASA's Center for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory.

Black Hole Rips Star Apart

Scientists announced that a rapidly spinning super massive black hole has been discovered tearing apart a sun-like star nearly four billion light years away. The All-Sky Automated Survey for Supernovae (ASASSN) detected a flash of light 3.8-billion-years ago in a distant galaxy briefly shone with 20 times the brightness of our entire galaxy. Instead of declaring it a supernova, an international team of astronomers now believes it was a star wandering too close to a spinning black hole. "We observed the source for 10 months following the event and have concluded that the explanation is unlikely to lie with an extraordinarily bright supernova. Our results indicate that the event was probably caused by a rapidly spinning supermassive black hole as it destroyed a low-mass star," said lead author of the study, Giorgos Leloudas.

Finland Northern Lights

Finnish photographer Tiina Tormanen captured Lapland like most have never seen before, set against the shimmering colors of the Aurora borealis. "I think it's nice to show people this silent beauty. And to remind people how amazing this planet is, how much there is beauty in life itself. You know when you are born and raised somewhere, your surroundings are normal and you don't even think about them, you just take it all for granted. But after spending 15 years in the southern cities, I saw the North in a different light and was even more blown away about the beauty of what we have here. It has been long journey but once you follow your passion it will lead you somewhere beautiful in the end," said Tormanen. Continue reading for another video, more pictures and information.

Amber Dinosaur Tail

Researchers at a Hukawng Valley amber mine in Myanmar have discovered an amber nugget containing the first preserved dinosaur tail covered in feathers. It's believed to come from a small, sparrow-sized dinosaur - likely a carnivorous coelurosaurus, which is part of a group that includes the Tyrannosaurus Rex - that went extinct approximately 99 million years ago. This part of the tail is from the tail bone, measuring just 2 millimeters across. The team believes that the top of the feathers were dark brown in color, while the underside could have been colorless. Click here to view the first image in today's viral picture gallery.

Seawater Battery

Researchers from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a new battery made from regular seawater. The device is basically a sodium-air battery, thanks to seawater being an excellent catholyte - a cathode and electrolyte combined together. "A constant flow of seawater into and out of the battery provides the sodium ions and water responsible for producing a charge," said one of the researchers.

Forze Delft VII

TU Delft students have revealed Forze Delft VII, a hydrogen-powered race car they hope one day will hit the streets worldwide. Not a hybrid electric / petrol and hydrogen vehicle, the 'VII' is a complete hydrogen-fueled car, meaning that the hydrogen is tanked. Together with oxygen from the air, these are converted into water and electricity. It also boasts a KERS (kinectic energy recovery systems), which can be found in hypercars, like the LaFerrari.
