Telescope team plans to track the whole sky
Physics World    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Funded with a five-year $4 million grant from the European Research Council, the 4 Pi Sky project will use a combination of ground- and space-based telescopes to study rare events such as colliding neutron stars and exploding supernovae. 4 Pi Sky combines three separate terrestrial telescopes systems. One is the Low Frequency Array, consisting of some 10,000 dipole antennas across Europe, that will be used to track objects at a frequency range of about 30–240 megahertz. The others are the MeerKAT array in South Africa and the Australian Square Kilometre Array Pathfinder in Western Australia, which will be used to track phenomena at higher frequencies of about 1 Gigahertz.

'Don't bump my atoms.' President Obama operates an electron microscope
The White House    Share    Share on FacebookTwitterShare on LinkedinE-mail article
During a visit to Intel's research and manufacturing facility in Oregon, President Barak Obama operated an electron microscope, and met with local science students. The president also remarked that "vanadium redox fuel cells" was probably the coolest thing he's ever said out loud. More

Provide feedback to National Science Foundation on Intellectual Merit and Broader Impacts review criteria
NSF    Share    Share on FacebookTwitterShare on LinkedinE-mail article
By the recently enacted America COMPETES Reauthorization Act, the National Science Foundation has been specifically required to apply a "Broader Impacts Review Criterion" to funding applications to achieve eight enumerated goals, including economic competitiveness, national security, public scientific literacy and greater participation of women and minorities in STEM fields. The agency was also required to clarify what activities would meet the criteria. To this end the National Science Board has fielded a Web-based comment form to get stakeholder thoughts on how to improve merit review at NSF. More

Electrons curve without help
American Physical Society    Share    Share on
FacebookTwitterShare on LinkedinE-mail article
In an upcoming issue of Physical Review Letters an experimental team shows that a "spin Hall" effect persists even when the electrons move smoothly through a lattice without scattering, as would occur in a future generation of very small devices. The results suggest that the effect will provide a powerful tool for controlling currents of both spin and charge in future "spintronics" devices. Researchers understand that the spin Hall effect is linked to the so-called spin-orbit interaction between an electron's spin and its physical motion. More



A new era of physics at the Large Hadron Collider

In January, at the annual meeting of the American Association for the Advancement of Science in Washington, D.C., theoretical physicist Lisa Randall of Harvard University spoke about her hopes for the Large Hadron Collider, the world's most powerful particle accelerator. She sat down with Science News physical sciences writer Devin Powell after her Feb. 19 talk to discuss what evidence the European collider, which is expected to operate at half power through 2012, might provide for her groundbreaking theories and for the Higgs mechanism, a process that would explain why particles have mass.

Atomic antennas transmit quantum information across a microchip
R & D Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An Austrian research group has experimentally demonstrated quantum antennae, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers. In their experiment, the physicists electromagnetically coupled two groups of ions over a distance of about 50 micrometers, each in its own double well potential. When the source group of ions oscillates it generates an oscillating electromagnetic field. If the receiving group of ions is tuned to this field, those ions pick up the signal of the source group, which results in coupling. This results in a coupling process and an energy exchange, which can be used to transmit quantum information. More

Signal amplification through bifurcation in nanoresonators
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The small size of micro- and nanomechanical resonators, combined with the slow decay of their vibrational modes, and their nonlinear dynamics enable numerous applications of these devices. In a paper published in Physical Review Letters, a group from Caltech and Tel Aviv University propose and implement a new bifurcation-based amplification scheme using coupled nanoresonators. The results bear not only on the fast expanding field of bifurcation-based robust small-signal amplification, but also on the physics of classical and quantum fluctuation phenomena in nonlinear vibrational systems, and on the dynamics and fluctuations near bifurcation points.

How to make a laser from a gin and tonic
Popular Mechanics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Making a liquid laser requires patience, but yields the world's coolest party trick: Hit it with enough focused energy, and a gin and tonic can be transformed from a predictable beverage into a super-chic space-age libation. Caution, do not drink the laser at the same time, and always wear eye protection when working in a laser environment. More

Imaging drug effects on tumors
Optics and Photonics News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Holographic tissue dynamics spectroscopy — a digital holographic imaging technique that can see motion in three dimensions as deep as 1 millimeter below the surface — allows researchers to look at motion inside living tissue. The system uses fluctuation spectroscopy and speckle images to examine how different sub-cellular components move, and how they respond to various drugs. More

Now is the time for science diplomacy in the Arab world
SciDev.net    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Science cannot resolve political conflict. But scientific cooperation can have a key role in maximizing post-conflict opportunities. Science diplomacy, an idea that has gained support in recent years, could play a major role in reassuring markets and restoring political stability in the months ahead. Done in a genuine spirit of partnership, this can lay the groundwork for advancing science and innovation helping all countries reach their full potential in building modern knowledge-based economies.
