Felix Baumgartner went faster than we thought

We followed the exploits of Felix Baumgartner and the Red Bull Stratos team with interest back in October of 2012. Baumgartner climbed into a specially designed capsule attached to a massive balloon and hitched a ride to 24 miles above the Earth’s surface. Once at that height, Baumgartner jumped.

Baumgartner wore a special pressure suit that allowed him to survive the extreme cold and speed he would achieve during his freefall back to earth. The goal of Baumgartner and his team was to become the first person to break the speed of sound without using an aircraft. Baumgartner and his team believe that they have set several world records, but the team’s findings haven’t been verified yet by the Federation Aeronautique International.

That is the international association that certifies record claims for aviation and aerospace achievements. Baumgartner and his team have come forward and announced that he actually achieved a speed faster than was originally reported. The original speed Baumgartner achieved was reported as 833.9 mph.

That speed worked out mach 1.24. The Red Bull team announced this week that Baumgartner actually achieved a maximum vertical speed of 843.6 mph, or Mach 1.25. Another change comes in the altitude from which Baumgartner leapt. The original altitude estimate was 128,100 feet. The new, more accurate report, is 127,852.4 feet.

You’ll Soon Be Able To Roll Up Your Home Stereo Like a Newspaper

Looking to expand its expertise outside imaging products, Fujifilm researchers have developed what’s called an electroacoustic film—which is basically a fancy way of saying an ultra-flat speaker that’s flexible enough to roll up and stash in your jacket pocket. More »

World’s largest prime number has over 17 million digits

Scientists and mathematicians are always working on ways to prove or disprove certain theories. Research seemingly never ends and often results in new discoveries. Researcher Curtis Cooper from the University of Central Missouri has recently discovered the world’s largest prime number. The prime number the researcher worked out has 17,425,170 digits.

Cooper made the discovery using the Great Internet Mersenne Prime Search or GIMPS program that networks PCs all around the world to search for a special type of prime number. Cooper’s discovery is 2 raised to the 57,885,161 power minus 1.

The significance of this discovery is in the fact that it is the first prime discovered in four years. The researcher admits that there is little mathematical value to finding a single new prime. However, discovering a new prime is very rare and described by mathematicians as “sort of like finding a diamond.” To get an idea of how massive the prime is, the text file is 22 MB of nothing but numbers.

If you skipped too many math classes during high school, a prime number is only divisible by itself and the number one. Another interesting factoid is that there are an infinite number of primes. So far the GIMPS project has discovered all 14 of the largest known Mersenne primes. Those numbers take their name from a French monk named Marin Mersenne who is known for studying the numbers 350 years ago.

Edited with (hopefully) a more accurate description from another source.

The Halley VI Modular Lab Keeps Moving to Avoid Death-by-Ice

The Antarctic ice shelf is among the most hostile, uninhabitable environments on the face of the Earth. However, with virtually zero atmospheric pollution and low levels of electromagnetic interference, it is also one of the best places on the planet for climate, atmospheric, and geological research. But how do you keep a team of scientists from becoming meat popsicles in a place where temperatures rarely top 0 degrees? With a ski-wearing modular laboratory, of course. More »

Creepy Smartphone Add-On Shocks Your Muscles For Realistic Force Feedback

When delivered through a vibrating motor in a controller or smartphone, force feedback isn’t particularly realistic. So researchers at Germany’s Hasso Plattner Institute have developed a new system for smartphones that uses electrical muscle stimulation to physically move the player’s hands and forearms in response to the action happening on screen.

Skeletal remains discovered under English parking lot belonged to King Richard III

If you’re not up on the history of England, you may or may not be familiar with King Richard III. He was one of the most heated of the ancient English kings who has been portrayed as evil monarch in various movies and plays throughout the centuries. What has been known about King Richard III was that he died on August 22, 1485 at the Battle of Bosworth Field.

What exactly happened to the unpopular king after his death remained a mystery for more than 500 years. Some reports from the time of the king say that his enemies threw his body into the river where it washed away never to be seen again. However, a group researchers and archaeologists have now confirmed “beyond a reasonable doubt” that the skeletal remains discovered under a modern parking lot are those of the former king.

Writer Philippa Langley discovered clues that led her to believe the King’s remains will be found under a parking lot in the corner of the buried ruins of the Greyfriars Priory. This idea came from the writings of the medieval historian John routes the road a few years after the teen died that he had been buried at the Priory.

The researchers believe that the Friars through King Richard III remains into an unmarked grave in buried him naked and without any of the adornments that typically went with a king’s burial. The researchers believe that the Friars buried the King quickly out of fear that those who had killed the King on the bow crowned might come looking for his remains. The body was reportedly buried in a grave so small that the cloven skull set at an angle against the edge of the grave. Mitochondrial DNA is what was used to prove beyond a reasonable doubt that these are in fact the remains of British royalty. The DNA was taken from two modern-day descendents of King Richard III for comparison.

Futuristic Antarctic research station can walk on ice

The Antarctic is a crazy place. The ice on the cold continent slowly moves toward the ocean at a rate of a quarter-mile every year, so establishing fixed structures isn’t necessarily feasible. However, a new kind of research station that’s set to open on February 5 has legs, and it can walk over the ice to avoid falling into the ocean.

antarctic-moving-station

Dubbed the Halley VI, the research station consists of eight stations that are connected together, all of which have these special legs so that the different pods can move in unison. The station consists of laboratories and sleeping quarters, with the larger red station acting as a communal living area that sports some pretty cool things, such as a climbing wall and a herb garden.

The legs consists of retractable hydraulic pumps that allow the structures to beat the rising snow level, and if the station needs to move, a bulldozer can tow the entire thing to a new location with ease. Honestly, they look like something straight out of Star Wars, and could be considered a smaller, more agile version of the AT-AT, but we digress.

Halley VI will be the most sophisticated research station to lay land on Antarctica, and while the laboratories on board are important, designers were specifically focused on making the station as cozy as possible. Architects made sure to select colors that were “refreshing and stimulating,” as well as putting daylight bulbs in lamps to simulate sunlight in order to prevent stress and depression during those long Antarctic winters.

Scientists create particles that are “nearly” alive

A group of scientists have created a new synthesized particle in the laboratory that is able to act in a lifelike way. The researchers are quick to say that particles aren’t truly alive, but they are able to behave in lifelike ways when exposed to light and fed by chemicals. When exposed to light and fed by chemicals the crystals are able to move, clump together, break apart, and reform.

crystal

Biophysicist Jérémie Palacci of New York University says that the line between active and alive is very blurry. Palacci and another New York University physicist Paul Chaikin are leading a group of researchers to develop the particles described as “living crystals” under the right conditions. The research being conducted by the team is in self-organizing collective behaviors.

The researchers say that studying these collective behaviors is easier in a controlled particle form than trying to study living creature such as schooling fish or flocking birds. Each of the tiny crystals is made from a cube of hematite, which is a compound made of iron and oxygen, covered in a spherical polymer coat. One corner of the hematite is left exposed.

When the particle is exposed to certain wavelengths of blue light, the hematite is able to conduct electricity. When those particles are placed in a hydrogen peroxide bath and the correct wavelength of blue light is shined on them, chemical reactions catalyze around the single exposed tip. Then as the hydrogen peroxide breaks down, the scientists say concentration gradients form. Random forces then pull the crystals apart, but the crystals eventually merge again. This process doesn’t stop until the blue light is turned off.

$1.35 billion grant for graphene development targets “strongest material ever”

Scientists have been talking up the potential of super-material graphene for years now, though dedicated efforts to actually exploit the material are only now really beginning to take off. Nokia has announced that the Graphene Flagship Consortium, of which it’s perhaps the best known member, has secured a $1.35 billion grant to help develop practical applications of graphene.

graphene,0-K-370676-3

Graphene is a 2-D structure that’s only one atom thick, yet it’s the strongest material ever produced being 300 times tougher than steel. The material is also one of the lightest conductors of electricity in existence making it highly appealing for use in electronic devices.

Nokia is a member of the Graphene Flagship Consortium that includes 73 other companies and academic institutions. The $1.35 billion grant the Consortium received is to be used for researching and development of graphene for practical applications, and was stumped up by the European Union for the Future and Emerging Technologies.

Nokia research leader Jani Kivioja says that not only does the graphene research consortium open up the research possibilities for the material, it also creates new jobs in Europe. The researcher suggests that, while its unlikely graphene will become a normal building material for various products, it is expected to be used to improve existing materials and products.
