Watching a metal transform into a superconductor, it may not be obvious that
this transition provides access to some of the same physics that governed the
cooling of the universe following the Big Bang. Yet at the root of both of these...

Ultracold atoms are still too hot. This may seem a ridiculous claim—after
all, the low-temperature exploits of the purveyors of quantum gases are
notorious. Laser cooling can flash-freeze atoms to temperatures in the micro-
and nanokelvin...

MIT physicists have discovered that several high-temperature superconductors
display patchwork quilt-like variations at the atomic scale, a surprising
finding that could help scientists understand a new class of unconventional
materials....

Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed
to electronic circuits and strength to materials like carbon composites, used in
airplanes and racecars. A major problem, however, is that the metals used to
grow...

Folding paper into shapes such as a crane or a butterfly is challenging
enough for most people. Now imagine trying to fold something that's about a
hundred times thinner than a human hair and then putting it to use as an
electronic device....

New research findings at MIT could lead to microchips that operate at much
higher speeds than is possible with today's standard silicon chips, leading to
cell phones and other communications systems that can transmit data much faster. ...

Equipment using wireless technology is becoming increasingly commonplace but
despite this up to 90 per cent of the radio spectrum can be idle in any one
location.
The failure to unlock the potential of this unused radio spectrum is...

An expert group for high performance calculations was officially established on
20 May 2009 at the Max Planck Institute of Plasma Physics (IPP) in Garching near
Munich. The team, named "High-Level-Support-Team" and supported financially
by...

When studying cold atoms, scientists often use magnetic or optical traps to keep
the atoms in place. However, in some cases experimentalists want to study free
atoms, avoiding the effects of a trap. "One way to study free atoms,"...

Scientists from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn,
Germany, Cornell University, USA, and the University of Cologne, Germany, have
detected two of the most complex molecules yet discovered in interstellar space:...

In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely
constructed,...

A remarkable new invention from Tel Aviv University — a network of tiny
sensors as small as dewdrops called "Smart Dew" — will foil even the most
determined intruder. Scattered outdoors on rocks, fence posts and...

New research suggests that the layer of insulation coating neural wiring in
the brain plays a critical role in determining intelligence. In addition, the
quality of this insulation appears to be largely genetically determined,
providing...

Abstract:
The ultimate electronic energy-storage device would store plenty of energy
but also charge up rapidly and provide powerful bursts when needed. Sadly,
today's devices can only do one or the other: capacitors provide...

Abstract:
An engineered metamaterial proved it can function as a state-of-the-art device
in the complex terahertz range of the electromagnetic spectrum, setting a
standard of performance for modulating tiny waves of radiation,...

A new light-bending material has brought scientists one step closer to creating
a cloaking device that could hide objects from sight.
Beyond possible military applications, it also might have a very practical use
by making mobile...
