Awesome Water + Sound Trick! Believe it or not, this is NOT photoshopped, what you cant hear is the speaker emmitting a sound at a frequency that interacts with the falling water, causing it to follow the shape of the oncoming sound wave.
Check out this cool video showing even more tricks you can do with it; http://bit.ly/12YZExr
Researchers at a US lab have passed a crucial milestone on the way to their ultimate goal of achieving self-sustaining nuclear fusion.
Harnessing fusion - the process that powers the Sun - could provide an unlimited and cheap source of energy.
But to be viable, fusion power plants would have to produce more energy than they consume, which has proven elusive.
Now, a breakthrough by scientists at the National Ignition Facility (NIF) could boost hopes of scaling up fusion.
NIF, based at Livermore in California, uses 192 beams from the world’s most powerful laser to heat and compress a small pellet of hydrogen fuel to the point where nuclear fusion reactions take place.
The BBC understands that during an experiment in late September, the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel - the first time this had been achieved at any fusion facility in the world.
This is a step short of the lab’s stated goal of “ignition”, where nuclear fusion generates as much energy as the lasers supply. This is because known “inefficiencies” in different parts of the system mean not all the energy supplied through the laser is delivered to the fuel.
But the latest achievement has been described as the single most meaningful step for fusion in recent years, and demonstrates NIF is well on its way towards the coveted target of ignition and self-sustaining fusion.

The California Nebula is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs.
Dinosaur Feathers Found in Ancient Amber
Instead of digging through rocks and rubble to find fossils, a group of Canadian paleontologists decided to dig through museums’ amber collections instead. Their unique approach paid off when they discovered feathers and never-before-seen structures, which they think are something called dinofuzz. As described in Science Now,
Some of the structures embedded in the amber don’t resemble anything seen on any creature living today.
The researchers combed through thousands of minuscule amber nuggets from nearly 80 million years ago. Among them they found 11 M&M-sized globules with traces of ancient feathers and fuzz. A number resembled modern feathers—some fit for flying and others designed to dive. And unlike fossils, the amber preserved colors too: white, gray, red and brown.
But a few hollow hair-like structures stumped researchers. The unidentifiable filaments weren’t plant fibers, fungus or fur, so the researchers surmise that they are protofeathers (thought to be the evolutionary precursors to feathers). Discovery News explains:
The collection is among the first to reveal all major evolutionary stages of feather development in non-avian dinosaurs and birds.
A Clearer History
The results, published in Science this week, give researchers a clearer picture of which ancient animals were feathered and the various purposes those structures served. As described in National Geographic:
The unusual find suggests a wide array of plumed creatures populated the time period—sporting everything from seemingly modern feathers to their filament-like forebears—and that even by this early date, feathers had become specialized, for example, for diving underwater.

Bobtail Squid by Todd Bretl
A series of portraits documenting the magnificent underwater creatures known as bobtail squids.
HOW THEY FIT IN WITH EVERYONE ELSE
The cephalopods are a class within the Phylum Mollusca.
In the class Cephalopoda, there are two subclasses:
Nautiloidea [the nautilus]
and Coleoidea [the squids, octopuses, and cuttlefish].
In the subclass Coleoidea, there are two superorders,
[the ten-footed (eight short arms, two long tentacles)]
and the Octopodiformes.
The bobtail squid are an order - Sepiolida - of Decapodiformes, an order separate from the [true] squids, which are the order Teuthida.

Today’s launch seen in false color Infrared — The Orbital Sciences Corporation Antares rocket, with the Cygnus cargo spacecraft aboard, is seen in this false color infrared image, as it launches from Pad-0A of the Mid-Atlantic Regional Spaceport (MARS), Wednesday, Sept. 18, 2013, NASA Wallops Flight Facility, Virginia. Cygnus is on its way to rendezvous with the space station. The spacecraft will deliver about 1,300 pounds (589 kilograms) of cargo, including food and clothing, to the Expedition 37 crew.

Concept: Disposable Food Bowl by Michal Marko
Designer Michal Marko created a disposable food bowl concept (with minimum environmental impact) while teaching society about new biodegradable materials. On the label it states: “Enjoy your food. Then put the seeds from under the label with gravel into the bowl and let it grow. After a week, plant bowl with a herb into the ground. The bowl will degrade and you can grown your own herb.” Can you imagine this bowl used in all fast-food restaurants? It would change our worldview. For this reason, I believe the concept is exceptional.
Atlantic Sabretooth (Coccorella atlantica) X-ray
Sabretooths live in the deep sea, an environment where feeding opportunities are scarce. To facilitate the essential opportunistic feeding habits needed for survival, deep sea fish have large mouths and distensible stomachs. This allows them to swallow prey than may even be larger than themselves.
The sabretooth in this image has swallowed a large fish, which can be seen folded up in its stomach. The fish’s recurved teeth prevent a captured fish from backing out and helps guide the prey down its pharynx.
