Researchers at Duke University Medical Center have devised an advanced technique that uses mass spectrometry to identify specific proteins that are over-expressed in cancer cells, blood, urine, or any substance that contains proteins.
Using this new technique, they have already identified two proteins – MIF and CyP-A — whose levels are elevated in lung cancer cells but not in normal cells, said Edward Patz, M.D., professor of radiology and pharmacology and cancer biology at Duke.
VTTs new device promotes clean combustion technology with high plant efficiency
VTT, Technical Research Centre of Finland, offers new opportunities to improve power plant efficiency with its globally unique research equipment. Most power plant types, independent of their fuel, use steam to produce energy. The first of its kind, VTTs equipment now enables steam to be brought to its supercritical state under research conditions. In this state, the steam may reach a temperatu
Building on their 2001 discovery of a cellular doorway used by anthrax toxin to enter cells, University of Wisconsin Medical School researchers have found a second anthrax toxin doorway, or receptor. The finding could offer new clues to preventing the toxin’s entrance into cells.
The researchers also have found that when they isolated a specific segment of the receptor in the laboratory, they could use it as a decoy to lure anthrax toxin away from the real cell receptors, preventing much o
Has an increasing trend in the Suns brightness contributed to global warming over the last few decades? One study published recently says it has but Judith Lean of the US Naval Research Laboratory will tell a joint session of the UK/Ireland National Astronomy Meeting and Solar Physics Meeting in Dublin that a different study has come to the opposite conclusion when she tackles the controversial topic of the relationship between our climate and the Sun on Tuesday 8 April.

May lead to sharper picture of human genome as well
Dana-Farber Cancer Institute scientists have used a powerful gene-mapping technique to produce the clearest picture yet of all the genes of an animal – the microscopic worm Caenorhabditis elegans (better known as C. elegans). Scientists believe the same technique may be used to bring the current, somewhat blurry picture of the human genome into sharper focus.
The study, which will be posted on the Nature Genetics website (
Scientists from the University of Minnesota demonstrated yields of corn and soybeans were only minimally reduced when organic production practices were utilized as compared with conventional production practices. After factoring in production costs, net returns between the two production strategies were equivalent.
More than 80% of corn and soybeans produced in the United States is grown in the Midwest, the vast majority with conventional production practices in a corn-soybean rotation requ
