Measuring protein level provides accurate assessment for patients with shortness of breath
A new blood test that measures a particular marker of cardiac distress can markedly improve the ability to diagnose or exclude congestive heart failure in patients with shortness of breath who come to hospital emergency departments. The report from researchers at Massachusetts General Hospital (MGH) finds that measuring levels of a protein called NT-proBNP was significantly better at identifying heart failure than was standard clinical evaluation. The report will appear in the April 15 issue of the American Journal of Cardiology and has been released online prior to print publication.
"We found that testing with the NT-proBNP assay was an extremely accurate way to identify or exclude heart failure in patients with shortness of breath," says James Januzzi Jr., MD, of the MGH Cardiology Division, the paper’s lead author. "Importantly, we also found that the very best results came from combining the results of this very sensitive and specific blood test with the logic and wisdom of a good emergency physician, which gave the optimal balance between biologic data and clinical judgement."

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
