Preliminary research on Fusarium, a group of fungi that includes devastating pathogens of plants and animals, shows how these microbes travel through the air. Researchers now believe that with improvements on this preliminary research, there will be a better understanding about crop security, disease spread, and climate change. Engineers and biologists are steering their efforts towards a new aerobiological modeling technique, one they think may assist farmers in the future by providing an...

Unfortunately, more than two million miles of the nation's infrastructure of water and wastewater pipelines are underground and nearing the end of their useful life. For state and local water utilities, making accurate predictions of exactly when the pipes might fail are extremely difficult since they are invisible to the human eye in their buried environmental conditions. In an effort to address this potentially serious problem, a national database on technologies to assess the conditions...

When a research team asked cocaine addicts to choose, hypothetically, between money now or cocaine of greater value later, "preference was almost exclusively for the money now," said Warren K., Bickel, professor in the Virginia Tech Carilion Research Institute, director of the Advanced Recovery Research Center, and professor of psychology in the College of Science at Virginia Tech. This result is significantly different from previous studies where a subject chooses between some money now or...

People lose the ability to detect the taste of iron in drinking water with advancing age, raising concern that older people may be at risk for an unhealthy over-exposure to iron, Virginia Tech engineers are reporting in results they term "unique." The study appears in the American Chemical Society's journal Environmental Science & Technology on Aug. 10. Andrea Dietrich, professor of civil and environmental engineering at Virginia Tech, and her colleagues, Susan Mirlohi, of Christiansburg,...

Stretching could improve efficiency of material used in batteries, fuel cells and water purification Researchers at Virginia Tech in Blacksburg, Va. recently found a way to improve electricity generating fuel cells, potentially making them more efficient, powerful and less expensive. Specifically, they discovered a way to speed up the flow and filtering of water or ions, which are necessary for fuel cells to operate. Simply put, the researchers stretched Nafion, a polymer electrolyte...

Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion ©, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its nanostructure, making it important for many energy-related industrial applications, including in fuel cells, organic batteries, and reverse-osmosis water purification. But since Nafion was invented 50 years ago, scientists have only been able to speculate about how to...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
