Watch digital tv and films without disruptions thanks to mathematical model
Dutch researcher Alina Weffers-Albu has developed a method to calculate how a device can provide maximum functionality with a minimum quantity of processor and memory capacity. TVs, DVD players and mobile phones can malfunction when the inbuilt chips and software cease to cope with the increasingly large flow of data.
What happens when you pop a quantum balloon?
When a tiny, quantum-scale, hypothetical balloon is popped in a vacuum, do the particles inside spread out all over the place as predicted by classical mechanics?
The new shape of music
The connection between music and mathematics has fascinated scholars for centuries. More than 200 years ago Pythagoras reportedly discovered that pleasing musical intervals could be described using simple ratios.
Scientists find a surprise when they look for what binds in superconductivity
For more than 20 years since the discovery of high-temperature superconductivity, scientists have been debating the underlying physical mechanism for this exotic phenomenon, which has the potential to revolutionize the electrical power distribution network.
Researchers make a point of explaining 'the wallpaper problem'
Frustrated by tape that won't peel off the roll in a straight line? Angry at wallpaper that refuses to tear neatly off the wall?

'Superdense' coding gets denser
The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of "wiggling" and "twisting" of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity for dense coding with linear optics.
Physicists show electrons can travel more than 100 times faster in graphene
University of Maryland physicists have shown that in graphene the intrinsic limit to the mobility, a measure of how well a material conducts electricity, is higher than any other known material at room temperature. Graphene, a single-atom-thick sheet of graphite, is a new material which combines aspects of semiconductors and metals.
Mit tests unique approach to fusion power
An MIT and Columbia University team has successfully tested a novel reactor that could chart a new path toward nuclear fusion, which could become a safe, reliable and nearly limitless source of energy.
U.S. experiment retakes the lead in race to find dark matter
Scientists of the Cryogenic Dark Matter Search experiment announced that they have regained the lead in the worldwide race to find the particles that make up dark matter. The CDMS experiment, conducted a half-mile underground in a mine in Soudan, Minn., again sets the world's best constraints on the properties of dark matter candidates.
After 30 years of study, rare particle confirms prediction
High-energy physicists devoted to recreating the conditions at the beginning of the universe have for the first time observed a new way to produce those basic particles of atoms, protons and neutrons.
