Quantum 'Trampoline' to Test Gravity
from NewScientist
It's the world's smallest trampoline. Bouncing atoms with lasers could make ultra-precise measurements of gravity. To test theories such as general relativity, the strength of gravity is measured precisely using ensembles of super cold atoms falling in a vacuum chamber. Full Article
Researchers Find Innate Correlations Among Different Power Law Phenomena
from PhysOrg
Studying the patterns that emerge in natural and social phenomena is a popular area of research, although usually individual phenomena are studied separately from each other. In a recent study, researchers have found innate correlations among some of these phenomena, showing that the amount of money that individuals in a society donate to a charity can be used to determine the distribution of personal wealth in that society.

Nanodevices Bend Under the Force of Light
from Scientific American
A team of researchers has fabricated a micron-scale device that deforms significantly under the force of light, a technology that could form the basis for tiny light-actuated switches or filters in future optical devices.

Quantum Processor Executes 160 Different Operations
from Physics World
Physicists in the U.S. have used two trapped atomic ions to create the first multiple-qubit programmable quantum computer. The device can be controlled to perform at least 160 different quantum computing operations. Its inventors claim that the device is an important step towards the development of a practical "universal quantum computer" that can be set to run any program allowed by quantum mechanics.

Titanic Thirty Meter Telescope Will See Deep Space More Clearly
from Wired
Four hundred years after Galileo's telescope revolutionized humanity's view of the universe, a gigantic telescope is in the works that could take us to a new, deeper level of understanding. Full Article
Using Photosynthesis to Power Hydrogen Production
from Ars Technica
Researchers have found that if they insert platinum nanoclusters into the photosynthetic machinery of bacteria, one acre could produce an amount of hydrogen equivalent to 79 gallons of gasoline per day. Full Article
A Physics Paradox: Holes That Block Light
from ScienceNow
The way light moves, with its fixed speed and its ability to act like either a wave or a particle, often leads to some of the most curious paradoxes of physics. A new one has just been found: Make holes in a film of gold so thin that it's already semitransparent, and less light gets through. Full Article
