Bursty behaviour found to have similar features across complex systems
Several complex systems live in periods of short bursts of high activity followed by long uneventful intermissions. This phenomenon called burstiness can be modelled and predicted with mathematical algorithms. Research of ...
Advancing quantum computing
European researchers have made important advances in understanding the major stumbling block to realisation of quantum computers, a phenomenon known as decoherence.
Let the sun shine and the plants will follow
Leonardo da Vinci, the Italian Renaissance scientist and artist extraordinaire, in the 15th century was the first to record his observation that some plants appeared to follow the Sun, and he was not the last. ...
NY tech fest heralds Silicon Valley of the East
The Big Apple may not have California's weather, but tech fans at New York Internet Week say that in every other way the city is on course to become Silicon Valley 2.0.
Sumatra faces yet another risk -- major volcanic eruptions
The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005.
Researchers demonstrate new way to control nonvolatile magnetic memory devices
(Phys.org) -- Cornell researchers have demonstrated a new strategy for making energy- efficient, reliable nonvolatile magnetic memory devices -- which retain information without electric power.
Magnetic fields can send particles to infinity
Researchers from the Complutense University of Madrid (UCM, Spain) have mathematically shown that particles charged in a magnetic field can escape into infinity without ever stopping. One of the conditions ...
New nano-measurements add spark to centuries-old theory of friction
The phenomenon of friction, when studied on a nanoscale, is more complex than previously thought. When friction occurs, an object does not simply slide its surface over that of another, it also makes a slight up-and-down ...
Physicists demonstrate quantum plasmons in atomic-scale nanoparticles
Addressing a half-century-old question, engineers at Stanford have conclusively determined how collective electron oscillations, called plasmons, behave in individual metal particles as small as just a few nanometers in diameter. ...
Laser lightning rod: Guiding bursts of electricity with a flash of light
Lightning is a fascinating but dangerous atmospheric phenomenon. New research reveals that brief bursts of intense laser light can redirect these high-power electrical discharges.
A study analyzes the causes of the trafficking of women in China
Research in which Universidad Carlos III of Madrid is participating analyzes the trafficking of women in China, a crime that is related to that country's great imbalance in the proportion of men to women, ...
Physicists surprised by disappearing and reappearing superconductivity in iron selenium chalcogenides
(PhysOrg.com) -- Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain ...
Saving data in vortex structures: New physical phenomenon could drastically reduce computer energy consumption
A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms ...
Angry Birds fly to Facebook
"Angry Birds", the most-downloaded mobile app of 2011, was catapulted to the world of Facebook on Tuesday in a bid by its Finnish maker Rovio to get one billion people playing the addictive game.
