Taming Magnetic Vortices: A Unified Theory for Skyrmion-materials

Taming Magnetic Vortices: A Unified Theory for Skyrmion-materials

March 4, 2015 11:49 am | by University of Cologne | News | Comments

In the future, magnetic vortex structures — so-called skyrmions — have the potential to store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, physicists have succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and have developed a unified theoretical description of their behavior.

Logic-defying Mathematical Model could lead to Better Skin Grafts, New Smart Materials

February 26, 2015 2:00 pm | by Cassi Camilleri, University of Malta | News | Comments

Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume tha,t when a force is applied along an axis, materials will always stretch and become thinner. Wrong. Thanks to their peculiar internal geometry, auxetic materials grow wider. After confounding scientists for decades, researchers are now developing mathematical models to explain the unusual behavior of these logic-defying materials

Flying Software Lab to Test Radically New Experimental Control Systems

February 26, 2015 8:35 am | by Suzanne Tracy, Editor-in-Chief, Scientific Computing and HPC Source | News | Comments

ESA is developing a mini-satellite to test out radically new control systems and techniques and to demonstrate drastically improved mission control capabilities that will arise when satellites can fly more powerful on-board computers. Known as Ops-Sat, it is made up of three CubeSat units with deployable solar panels. Although only 30 cm high, it contains an experimental computer 10 times more powerful than any current spacecraft.

PNNL Shifts Computational Chemistry into Overdrive

February 25, 2015 8:29 am | by Karol Kowalski, Ph.D., and Edoardo Apra, Ph.D. | Articles | Comments

We computational chemists are an impatient lot. Despite the fact that we routinely deal with highly complicated chemical processes running on our laboratory’s equally complex HPC clusters, we want answers in minutes or hours, not days, months or even years. In many instances, that’s just not feasible; in fact, there are times when the magnitude of the problem simply exceeds the capabilities of the HPC resources available to us.

Named after a legendary sea monster, Kraken Mare is believed to be the largest body of liquid on the surface of Saturn's moon Titan. It extends nearly 150,000 square miles across the moon's north-polar region and is made of liquified hydrocarbons. According to a conference presentation given at the 2015 NASA Institute for Advanced Concepts Symposium, NASA hopes to send a submarine to explore the frigid methane sea by 2040.

Mars is the Next Step for Humanity – We Must Take It

Elon Musk has built a US$12 billion company in an endeavour to pave the way to Mars for humanity. He insists that Mars is a “long-term insurance policy” for “the light of consciousness” in the face of climate change, extinction events, and our recklessness with technology. On the other hand, astronaut Chris Hadfield is sceptical: “Humanity is not going extinct,” he told me.

Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.

Time to Examine Purposely Cooling the Planet?

It's time to study and maybe even test the idea of cooling the Earth by injecting sulfur pollution high in the air to reflect the sun's heat, a first-of-its-kind federal science report said on February 10, 2015. The idea was once considered fringe — to purposely re-engineer the planet's climate as a last ditch effort to battle global warming with an artificial cloud. No longer.

Speed Record: Octopus Robot’s Ultra-fast Acceleration is Unprecedented

Scientists have developed an octopus-like robot  that can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles. Cephalopods are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away. Inspired by this, scientists built a deformable robot with a 3-D printed skeleton, no moving parts and no energy storage device.

The gone-but-not-forgotten spacecraft Beagle-2 went AWOL on Christmas Day, 2003, when it was supposed to land on Mars and start transmitting data back to Earth. Instead, the British-built craft went dark. After several months, it was declared lost — presumed to have been destroyed during its approach or while trying to land on the red planet.

If you’re sitting in a coffee shop, tapping away on your laptop, feeling safe from hackers because you didn’t connect to the shop’s Wi-Fi, think again. The bad guys may be able to see what you’re doing just by analyzing the low-power electronic signals your laptop emits, even when it’s not connected to the Internet. Side-channel signals could provide hackers with another way to see what the devices are doing.
