Improvements in echocardiographic sequence and mammogram analysis techniques lead to earlier detection of disease and defects.

Imaging various parts of the body is an established and important method for the diagnosis of diseases such as breast cancer, and is also used extensively for the detection of abnormalities in organs such as the heart. Accurate interpretation, and ultimately correct diagnosis, is dependent on the quality of the images. High quality images, however, can often b

A group of scientists from The Scripps Research Institute (TSRI) and several other institutions has solved the structure of an antibody that effectively neutralizes human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS).

The antibody binds to sugars on the surface of HIV and effectively neutralizes the virus because of its unique structure, which is described in the latest issue of the journal Science.

“What we found was an unusual conf

Scientists have developed a hydrogen-making catalyst that uses cheaper materials and yields fewer contaminants than do current processes, while extracting the element from common renewable plant sources. Further, the new catalyst lies at the heart of a chemical process the authors say is a significant advance in producing alternate fuels from domestic sources.

In the June 27 issue of the journal Science, James Dumesic, John Shabaker and George Huber, of the University of Wisconsin at Madis

Through many decades, stories about earthquakes raising or lowering water levels in wells, lakes and streams have become the stuff of folklore.

Just last November, the magnitude 7.9 Denali earthquake in Alaska was credited with sloshing water in Seattle’s Lake Union and Lake Pontchartrain in New Orleans, and was blamed the next day when muddy tap water turned up in Pennsylvania, where some water tables dropped as much as 6 inches.

But the relationship between seismic activity and

An updated edition of Sources and Prices of Selected Medicines and Diagnostics for People living with HIV/AIDS will be released today. The report provides market information on 74 reviewed products for the treatment and management of HIV/AIDS from 61 manufacturers.

The report gives purchasers of AIDS medicines and diagnostics a range of choices related to suppliers and affordability. The medicines included were selected on the basis of WHO standard treatment guidelines. The list is n

EU satellite research project tackles urban air quality from space

A three-year project led by the Commission with ten partners from Greece, Germany, Hungary and Italy has developed an innovative system for monitoring and managing urban air quality and the related health risks. Results of the “ICAROS NET” technique were presented today in Budapest. ICAROS uses satellite-borne sensors to monitor the concentration of harmful particles in the air, caused by heavy industry, traffic and ho
