The common origin of superconductivity in iron-based compounds
Materials Today
Beyond their superconductivity, iron pnictides (parent compound CaFe2As2) and the iron chalcogenides (parent Fe1+yTe) have important features in common, such as their band structures and magnetic excitations. A team of researchers from the U.S., China and the U.K. have found that even though the nearest neighbor exchange couplings between chalcogenide and pnictide atoms are different, the next nearest neighbor exchange couplings are similar. This implies that the key magnetic exchange thought to be responsible for high temperature superconductivity may occur here rather than in adjacent atoms as predicted by first principles density functional calculations.More

Africa tweeting for science
SciDev.Net
Africa's mobile Internet boom could revolutionize the way scientists, policymakers and the public interact, says Linda Nordling. Most Africans access the Internet through their mobile phones. The ITU reports that usage of the mobile Internet overtook fixed connections in Africa in the last quarter of 2009. This development will open up new lines of communication between scientists, policymakers and the public.More

ICTP releases book on design of mobile applications for science
ICTP Science Dissemination Unit
The Science Dissemination Unit of the Abdus Salam International Centre for Theoretical Physics has released the primer open book on "m-Science: Sensing, Computing and Dissemination." The book was written by experts in an effort to engage the scientific community, engineers and scholars worldwide in the design, development and deployment of the newest mobile applications. The goal is to create awareness on the huge possibilities of mobile science as well as to motivate a new generation of learners, scholars and scientists to participate in the challenges of the rapidly developing new field of m-Science.More

Open access gets more readers, but not more citations
SciDev.Net
A paper published March 30 in The FASEB Journal analyzed more than 3,000 articles from 36 journals. It found that although open access papers are downloaded more, they are not cited by other scientists any more than paid-for articles.More

Physicists discover new way to visualize warped space and time
EurekAlert
When black holes slam into each other, the surrounding space and time surge and undulate like a heaving sea during a storm. This warping of space and time is so complicated that physicists haven't been able to understand the details of what goes on — until now. Physicists at Caltech, Cornell University, and the National Institute for Theoretical Physics in South Africa have developed conceptual tools they've dubbed tendex lines and vortex lines. More

2 dying stars to be reborn as 1
ScienceDaily
White dwarfs are dead stars that pack a sun's-worth of matter into an Earth-sized ball. Astronomers have just discovered an amazing pair of white dwarfs whirling around each other once every 39 minutes. This is the shortest-period pair of white dwarfs now known. Moreover, in a few million years they will collide and merge to create a single star.More

Do plants have magnetic fields?
UC Berkeley
Using some of the most sensitive magnetic detectors available, physicists at the University of California, Berkeley, tried to measure magnetic fields around a titan arum, the world's largest flower. Though the interference from local BART trains and traffic bedeviled the experiment, and their ultimate failure to detect a magnetic field, they did establish that the plant generated no magnetic field greater than one-millionth the strength of the Earth's magnetic field.More

Quantum interference of large organic molecules
Nanowerk News
A quantum interference experiment on a molecular system of more than 400 atoms has set a new record for the verification of the quantum properties of nanoparticles. In addition, an important aspect of the famous thought experiment known as "Schroedinger's cat" was probed. The experiment shows that even complex systems, with more than 1,000 internal degrees of freedom, can be prepared in quantum states that are sufficiently well isolated from their environment to avoid decoherence and to show almost perfect coherence.

Australian photonics center aims at vast improvements in Internet
IT Wire
Australia has officially kicked of a six year $23.8 million research program into photonic chip technology at the Australian Research Council's Centre of Excellence for Ultrahigh bandwidth Devices for Optical Systems. CUDOS has the potential to revolutionize optical communications. CUDOS is a collaboration between seven Australian universities with photonic research programs.More

Florida A&M University researchers, NSBP members, award patent for Cerenkov Detector
The Famuan
Professor Eliott Treadwell and his former graduate student, Dr. Ely Leon, have been awarded a U.S. patent for their Threshold Cerenkov Detector with Radial Segmentation. The detector provides a method of providing nuclear particle identification for e, mu, pi and p of up to about 4 to about 5 GeV/c.More
