As outlined in a series of articles in the online open access publication, Malaria Journal, the World Antimalarial Resistance Network (WARN) aims to provide a globally co-ordinated effort to tackle the disease, which is estimated to kill between 1 and 2.7 million people every year.
One of the major aims of WARN is to facilitate worldwide monitoring and characterisation of drug resistance, particularly that to the latest generation of antimalarial drugs, artemisinin-based combination therapies (ACTs).
WARN will consist of four linked, global, open-access, web-based databases containing four kinds of data:·Clinical drug efficacy
WARN’s founders hope that the databases will help speed up the publication process for scientists. This, in turn, means that policymakers and malaria control managers will have access to timely information on the temporal and geographic trends of drug resistance, allowing them to take action as soon as resistant malaria parasites are detected.
Drug resistance is a major threat to the control and eradication of malaria and can lead to treatment failure, increased spread of the disease, and higher morbidity and mortality. Many ‘old’ antimalarials, including chloroquine and mefloquine, are now of limited use because of drug resistance.
Today, over 50 countries recommend ACTs as first-line therapy for falciparum malaria, the most severe form of the disease. While these newer treatments are currently effective, researchers know that resistance to ACTs will emerge in the future.
The network is being launched after a meeting of leading malaria researchers and policymakers sponsored by the Bill and Melinda Gates Foundation held at the Wellcome Trust/Sanger Centre, Cambridge, UK in late 2006.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
