Trend comes despite critical public health need
Despite a critical need for new antibiotics to treat drug-resistant infections and other infectious diseases, very few new antibiotics are being developed, according to a study in the May 1 issue of Clinical Infectious Diseases, now available online.
To document trends, researchers evaluated Food and Drug Administration (FDA) databases of approved drugs and the research and development (R&D) programs of the worlds largest pharmaceutical and biotechnology companies, by looking at the companies websites and 2002 annual reports. They found that FDA approvals of new antibiotics declined 56 percent during the past 20 years (1998-2002 versus 1983-1987). Looking to the future, the researchers found only six new antibiotics in the R&D pipeline out of 506 drugs being developed. One of those drugs, telithromycin, was approved by FDA this month.

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...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
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...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
