Clinical tests began today of a novel vaccine directed at the three most globally important HIV subtypes, or clades. Developed by scientists at the Dale and Betty Bumpers Vaccine Research Center (VRC), part of the National Institute of Allergy and Infectious Diseases (NIAID), the vaccine incorporates HIV genetic material from clades A, B and C, which cause about 90 percent of all HIV infections around the world.
“This is the first multigene, multiclade HIV vaccine to enter human trials,” no
For the first time in the world, researchers at the University of Newcastle upon Tyne, UK, along with collaborators at the University of Oxford, Harvard University, and Michigan State University have uncovered two genetically informative molecules from a single fossil bone. In addition to the recovery of mitochondrial DNA, the complete sequencing of a bone protein, osteocalcin, makes this a major scientific breakthrough. Extending this work to additional fossils could change perceptions of evolutiona
Study by researchers from Syracuse University, Syracuse, N.Y., and Union College, Schenectady, N.Y., to be published in the Nov. 14 issue of Nature
El Niño, the pattern that can wreak havoc on climate conditions around the world, is like a beacon, pulsating through time on a 2,000 year cycle, according to a new study by scientists from Syracuse University, Syracuse, N.Y.; Union College, Schenectady, N.Y., and from the NOAA Paleoclimatology Program, Boulder, Colo., that is being publis
The European DataGrid (EDG)* project has taken a major step towards making the concept of a world-wide computing Grid a reality. Its latest release of middleware – the software that makes a Grid of computers work together seamlessly – will support production quality Grid computing. Markus Schulz, one of the chief software developers at CERN**, explains, “This release will take the EDG project from the laboratory bench into the real world”.
One of the main aims of the European DataGrid proje
An ambitious, multi-disciplinary, 15-20 year program to fill in and flesh out the Tree of Life has just been launched by the National Science Foundation.
Field Museum scientists will help lead three of the seven grants recently awarded to researchers around the world to construct a new framework for understanding the evolutionary relationships between all species, extinct and living.
These three projects (listed below) will focus on birds, spiders, and archosaurs (birds, dinosaurs, pt
From 800 km in space, you would have to squint really hard to see one of these – a micron-sized phytoplankton and its armoured shell. But when a lot of them get together, say, a few trillion or so…
…what you see is the image below from the European Space Agency’s Medium Resolution Imaging Spectrometer (MERIS) instrument. The sensor, carried onboard the Envisat satellite, acquired imagery of a phytoplankton bloom that occurred this summer in the north Atlantic, off the coasts of Nova Scotia
