Research Update: Atomic Motions Help Determine Temperatures Inside Earth
In December 2011, Caltech mineral-physics expert Jennifer Jackson reported that she and a team of researchers had used diamond-anvil cells to compress tiny samples of iron-the main element of the earth's core. By squeezing the samples to reproduce the extreme pressures felt at the core, the team was able to get a closer estimate of the melting point of iron. At the time, the measurements that the researchers made were unprecedented in detail.

Graphene plasmonics beats the drug cheats
Graphene plasmonics beats the drug cheats
Writing , the scientists, working with colleagues from Aix-Marseille University , have created a device which potentially can see one molecule though a simple optical system and can analyse its components within minutes. This uses plasmonics – the study of vibrations of electrons in different materials.

New qubit control bodes well for future of quantum computing
New qubit control bodes well for future of quantum computing
Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing. Quantum computers would be exponentially faster than the most powerful computers of today.

A Clock Einstein Would Have Loved
A very special clock that can measure time on the basis of the mass of a single atomic or even subatomic particle holds promise not only for ultraprecise measurements of mass and time, but also for such exotic applications as testing Einstein's general theory of relativity, or the effects of gravity on antimatter.

Another Tool in the Nano Toolbox: Berkeley Lab Scientists Use Electron Beam to Manipulate Nanoparticles
Nanotechnology, the manipulation of matter at the atomic and molecular scale, holds great promise for everything from incredibly fast computers to chemical sensors that can sniff out cancer cells. But how does one go about building a device made of parts that are one-billionth of a meter in size? Over the years, scientists have developed tools for this microscopic handiwork.

Penn Physicists Help Create 'Recipe Book' for Building New Materials
Penn Physicists Help Create ’Recipe Book’ for Building New Materials
By showing that tiny particles injected into a liquid crystal medium behave as predicted by existing mathematical theorems, physicists have opened the door for the creation of a host of new materials with properties that do not exist in nature.
