Blog - Physicists Build Single Atom Memory For Quantum Information
A single of atom of rubidium sits at the heart of an exotic new quantum memory device
One of the building blocks for the next generation of quantum computing and communications systems is a way of storing and regenerating photonic qubits. These are generally encoded in the polarisation of photons.

06:00In this video, a mouse with a fiberoptic cable implanted into his brain explores a four-arm maze. The animal has been genetically engineered to express light-sensitive proteins in a specific part of the amygdala, a brain region linked to fear. Mice are naturally afraid of open spaces, and at the beginning of the video, the mouse spends most of his time in one corner of the maze, occasionally dashing out to explore his environment. Turning on the light (as indicated by blue text) activates a specific neural circuit, which appears to make the mouse much braver, continually exploring all the parts of the maze. The video is shown at ten times normal speed.

A small number of randomly selected legislators should make parliaments more effective, say a group of IgNobel price-winning scientists
The democratic system of governance is one of the triumphs of civilisation. It ensures that our societies are run in the best interests of the majority. At least, that's the theory.

Scientists implanted urethras engineered from the patient's own cells, restoring normal function.
Five young men given urethra grafts engineered from their own cells are doing well six years later, according to a study published this week in the Lancet. The boys' own urethras had been severely damaged by illness or accidents.

Magnetic-field energy storage could have unique advantages, but scaling up will be a challenge.
Superconducting magnetic energy storage (SMES) has long been pursued as a large-scale technology because it offers instantaneous energy discharge and a theoretically infinite number of recharge cycles. Until recently, however, the material costs for SMES devices have been prohibitively high for all but very small applications. Now a project funded by the

Physicists have demonstrated a key enabling technology for quantum computing
In 2001, a team of physicists from IBM and Stanford University in Silicon Valley revealed that they had built a remarkable computer capable of exploiting the strange rules of quantum mechanics to process information.

Physicists have designed a memristor processor that uses a massively parallel approach to solve mazes.
Memristors are the fourth fundamental building block of electronic circuits, after resistors, capacitors and inductors. They were famously predicted in the early 1970s but only discovered 30 years later at HP Labs in Palo Alto, California.

ARPA-E will get a funding increase at a time when many programs face cuts.
Two years after it was created, and despite having received little initial funding, the Advanced Research Projects Agency for Energy (ARPA-E) is receiving support within Congress as a way to address concerns about energy security, the economy, and national security. While Congress contemplates major cuts in many programs, Republicans and Democrats in the House have voted to increase funding for the agency above current levels.

Theoretical predictions about the way ripples move over icicles have finally been observed in experiments
A strange feature of icicles is that their surfaces can sometimes become rippled, as in the picture above. The wavelength of these ripples is always about a 1cm.

A new printing process could increase battery capacity by over 10 percent.
Xerox's Palo Alto Research Center (PARC) has developed a new printing technology that promises to pack more energy into batteries for electric vehicles. By printing a striped pattern of energy storage materials and highly conductive materials, researchers at PARC are making electrodes that are much thicker than those in conventional batteries. These could increase battery storage capacity by 10 to 30 percent while costing little more to manufacture, says

Working out exactly where projected droplets came from using their spatter pattern has never been possible...until now.
Here's an interesting problem. Imagine a crime scene in which blood has spattered across a floor. Is it possible to use the spatter pattern to determine the position of the source in three dimensions?
