The WaterWheel — Wello Water

In September 2011, the Wello team arrived in India with the goal of answering one big question: “How might we improve the experience of collecting, storing, and using water?” Over the course of the past 15 months, we’ve interviewed over 1500 community members, practitioners and experts, spent countless hours designing and prototyping in the field, and carried hundreds of liters of water. We developed a wide range of concepts and designs in collaboration with the WaterWheel’s intended users, identified the features that were most important to them, and developed a prototype. We’re thrilled to introduce you to the WaterWheel 2.0! It’s…CONVENIENT. It’s…HYGIENIC The WaterWheel’s cap-in-cap design prevents recontamination at the point of use. It’s…HIGH QUALITY. It’s..AESTHETICALLY PLEASING. AND it’s…AFFORDABLE.

First step to reduce plant need for nitrogen fertilizer uncovered Related images(click to enlarge) University of Missouri Nitrogen fertilizer costs U.S. farmers approximately $8 billion each year, and excess fertilizer can find its way into rivers and streams, damaging the delicate water systems. "The problem is that corn, tomatoes and other crops have a different response and don't support an intimate interaction with the rhizobia, thus making farmers apply larger amounts of nitrogen than might otherwise be necessary," Stacey said. When legumes like soybeans sense a signal from the bacteria, they create nodules where the bacteria gather and produce atmospheric nitrogen that the plants can then use to stimulate their growth. "There's this back and forth battle between a plant and a pathogen," said Yan Liang, a co-author of the study and post-doctoral fellow at MU. In the study, Stacey and Liang treated corn, soybeans, tomatoes and other plants to see how they responded when exposed to the chemical signal from the rhizobia bacteria.

Ebola Treatment May Be On the Horizon - At the Edge A medical worker from the U.S. Centers for Disease Control and Prevention works at a laboratory in Entebbe, Uganda where researchers are working on the Ebola outbreak on Thursday Aug. 2, 2012. U.S. Army medical researchers may have found an emergency treatment for the deadly Ebola virus, which is welcome news to biodefense researchers studying ways in which such hemorrhagic fever viruses jump from non-primate species to human beings and how to treat them. Using antibodies derived from specially engineered tobacco plants, Army medical researchers were able to develop a treatment that provided complete protection for monkeys shortly after they were exposed to Ebola.
