Mathematicians from the University of Exeter have solved the mystery of traffic jams by developing a model to show how major delays occur on our roads, with no apparent cause. Many traffic jams leave drivers baffled as they finally reach the end of a tail-back to find no visible cause for their delay. Now, a […]

Known in America chiefly as the bane of hikers, the single-celled intestinal parasite Giardia lamblia is a major cause of diarrheal illness worldwide with estimates of 100 million infections a year. The parasite colonizes the upper small intestine by fastening to the microvillus brush border of intestinal cells.But exactly how Giardia attaches itself was unknown […]

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have developed a new tool for quantitatively measuring elusive atmospheric chemicals that play a key role in the formation of photochemical smog. Better measurements will improve scientists’ understanding of the mechanisms of smog formation and their ability to select and predict the effectiveness of various […]

Using concentrated solar energy to reverse combustion, a research team from Sandia National Laboratories is building a prototype device intended to chemically “reenergize” carbon dioxide into carbon monoxide using concentrated solar power. The carbon monoxide could then be used to make hydrogen or serve as a building block to synthesize a liquid combustible fuel, such […]

MIT scientists have found a way to induce cells to form parallel tube-like structures that could one day serve as tiny engineered blood vessels.The researchers found that they can control the cells’ development by growing them on a surface with nano-scale patterning.
Engineered blood vessels could one day be transplanted into tissues such as the kidneys, […]
