Woolly mammoth research center to open.
A joint initiative between a Russian university and a South Korean research center will see the center open in Russia’s Sakha Republic this month.
The area, in the North of Russia, is home to 80 percent of Russia’s mammoth remains, thanks largely to the cold conditions which have been able to preserve some remarkably well preserved finds, including mammoth blood still inside one carcass.

"To send material to our [Korean] colleagues is not so simple," Semyon Grigoryev,  head of the mammoth laboratory at Yakutsk’s Northeastern Federal University, said in comments carried by Interfax.

"We have to obtain a license for this and the process can take nearly six months. Here at the center, scientists can conduct preliminary research on the spot rather than wait for a permit to export their material. This will make work significantly easier for everybody."

Video: NASA test firing of their new 3D printed rocket.

NASA was able to reduce the number of components in this rocket’s injector from 163, down to just two, by using a printing technology called “selective laser melting”.

Worlds fastest camera shoots 4.4 trillion frames per second.
A Japanese team has created a recording device able to acquire 4.4 trillion images per second, at a 450 x 450 pixel resolution. The technique could be used to further research into heat conduction and chemical reactions, according to its creators.
If the resolution can be improved, it could also prove useful for manufacturing, where it could keep track of laser cuttings in real time.

The technique, known as a Sequentially Timed All-optical Mapping Photography, or STAMP for short, shuns the conventional methods employed by other superspeed cameras to achieve results up to 1,000 times faster than has been previously available. The current leading brand of high-speed real-time recording is a method unfortunately known as the pump-probe process, where light is “pumped” at the subject and then “probed” for absorption. STAMP differs from this by skipping the need to constantly probe, or measure, the scene to construct an image, instead it uses single-shot bursts to acquire images and maps the spatial profile of the subject to the temporal profile at a 450x450-pixel resolution.

Photos: Mammoth skeleton unearthed.

A Texas family business has discovered a ‘90% complete’ mammoth skeleton in their gravel pit, after striking a 6ft long tusk with an excavator.

The find has been donated to the nearby Perot Museum, which is working to remove the skeleton, which is estimated to be a 9ft (2.7m) tall female which died between 20,000 to 60,000 years ago.

8 Bit Future’s back (from the future?)
A few issues with 8bitfuture.com over the last couple of weeks have been resolved. My hosting provider completely disappeared, taking 6,000 websites with it by the look of things on their Facebook page, so the domain is now handled through GoDaddy which should be a bit more reliable, if not more expensive, but a good lesson that when it comes to the internet, you get what you pay for.
The image above is from a 2010 proposal to send ‘tumbleweed probes’ to Mars, where they could be moved around by wind instead of driving on six wheels like the currently active NASA rovers there. Video of the rovers here.
Another interesting space story this week is about the state of Curiosity’s wheels, which are currently developing large holes that could put the extended mission in jeopardy. The short version is that NASA didn’t realise just what kind of rocks they’d be dealing with, but the rover could continue indefinitely if they take it to more soft sandy areas. Below is a photo of a replica wheel, tested to breaking point here on Earth. Interesting to see it with a human - I never realised how big the rover was until seeing one of it’s wheels! Check out the full story here at Gizmodo.

Video: NASA’s ‘flying saucer’ tested in the upper atmosphere.

NASA is testing a “flying saucer” designed to land on Mars and deliver large payloads to the Red Planet, and the agency has released a spectacular video of a high-altitude test conducted over Hawaii this past June. In it, the Low Density Supersonic Decelerator (LDSD) is brought up 180,000 feet high into earth’s atmosphere, a place where conditions are similar to those on Mars. After confirming that the vehicle could fly in these conditions, NASA then tried to slow the craft down with two new technologies — a funky, donut-shaped “Supersonic Inflatable Aerodynamic Decelerator” and a massive supersonic parachute.

"Visual microphone" can decode words from the vibrations in an object.

A MIT student has shown how the tiny vibrations caused by sound waves can be picked up by a high speed video camera, and decoded with software to figure out what sounds were being made.

The technique allows the researchers find out the subject of a conversation, for example, by watching the vibrations in a glass of water or a bag of chips.
