Scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) have produced the first ever action movies starring individual water molecules on a metal surface. The ending was a surprise even to the producers.
Working with a unique scanning tunneling microscope (STM), a team led by Miquel Salmeron, a physicist with Berkeley Labs Materials Sciences Division, cooled the surface of a single crystal of palladium, a good catalyst for reactions involving hydrogen and water, to a tem
If people were computers, Srinidhi Varadarajan of Virginia Tech’s Department of Computer Science could enable them to go back to their youth to correct mistakes they made, adapt a jet engine to run a car, or change a part from one SUV engine to another as both vehicles sped down a highway side by side.
Of course, people aren’t computers and don’t need to do those things, but computers need to do equivalent processes. Varadarajan has come up with a computer technology he calls “Weaves” that
“We need to get (chronic kidney disease) on the radar screen, especially when theres a medical history of high blood pressure or diabetes, so both patients and physicians are more aware of the consequences and opportunities to intervene.” – Neil R. Powe, M.D., M.P.H.
Kidney disease patients are at a much increased risk of death when they have delays getting to a specialist, a Johns Hopkins-led study shows. Delays occur more often among black males, the uninsured and those who have mul
Budding computer experts from around the world will this week begin their own tests of the latest software developed by the European DataGrid Project. Students attending the 2002 CERN School of Computing in Vico Equense, Italy, will be submitting jobs that can run anywhere on the Project’s current Grid, which is based at 10 computer centres throughout Europe. This is the first in a series of important tests using software from the DataGrid Project that will take place throughout the autumn, and which
British astronomers, together with Australian and American colleagues, have used the 3.9m Anglo-Australian Telescope [AAT] in New South Wales, Australia to discover a new planet outside our Solar System – the 100th to be detected. The discovery, which is part of a search for solar systems that resemble our own, will be announced today (Tuesday) at a conference on “The origin of life” in Graz, Austria. This takes the total number of planets found outside our solar system to 100, and scientists are now
A pediatrician at Brenner Childrens Hospital has developed an efficient way to help educate health care professionals on herbal and dietary supplements via the Internet, according to a study published in the September issue of Academic Medicine.
Kathi Kemper, M.D., a pediatrician at Brenner Childrens Hospital, worked with physicians from the Longwood Herbal Task Force to develop a series of e-mails containing information and questions about various herbal and dietary supplements.
