Madrid Begins Electric Bike Sharing

For something that took years to arrive, Madrid’s public bicycles sure get off to a fast start. Pedal once and the 36-volt, 10-ampere, electric motors will give you a sudden boost. Going up one of Madrid’s many hills, it is a welcome aid. Downhill, the burst jars. But riders can disable the boost by not pedaling, and moderate it with electric controls on the handlebars. With a little practice, the bikes begin to feel like underpowered motor scooters. “Our major goal is to move journeys that are now done by car to the bicycles,” says Elisa Barahona, Madrid’s director of sustainability and environment.

Hospital To Use Microfluid Prototype For Diagnosing Tumors

10.22.13.research.Lucas.16-10-2013-14-28-Chemist Emmanuel Delamarche held a thin slice of human thyroid tissue on a glass slide between his fingers. The tissue poses a mystery: does it contain a tumor or not? Delamarche, who works at IBM Research in Zurich, Switzerland, turned the slide around in his hand as he explained that the normal method of diagnosing a tumor involves splashing a chemical reagent, some of which are expensive, onto the uneven surface of the tissue and watching for it to react with disease markers. A pathologist “looks at them under a microscope, and he’s using his expertise, his judgment, and looks at what chemical he used, what type of color he can see and what part and he has to come up with a diagnosis,” Delamarche says, “he has a very, very hard job, OK?”

IBM is already good at precise application of materials to flat surfaces such as computer chips. Human tissue, sliced thin enough, turns out to receptive to the company’s bag of tricks too. Delamarche, turning to one of three machines on lab benches, explained that a few years ago his team began trying to deliver reagents with more precision. University Hospital Zurich will be testing the results over the next few months.

Inside the World’s Largest Carbon-Capture Test Facility

In a laboratory on Norway’s fjord-laced coast, Jane Feste bubbles some carbon dioxide gas through a liquid for a crowd of visitors. “I will take an amine—that’s a base—and that will absorb…the CO2. So [that’s] what’s happening out in the plant, just shown for the eye here,” the laboratory technician explains. She’s referring to Technology Centre Mongstad (TCM), the US $1 billion, 350-megawatt power plant and test facility that the Norwegian government and several energy firms built. The assembled journalists cannot seem to decide if they should applaud the spectacle or if they’re witnessing a modern case of the emperor’s new clothes. Continue reading

Spain replants after centuries of deforestation

First broadcast and published by Deutsche Welle: [html] [mp3]

Around this time of year in the Sierra de Guadarrama, a snow-capped mountain range outside Madrid, the snow is starting to melt. Below the tree line, the melting water soaks the earth in dense stands of pine trees. Further down, holly, oak and ash trees line the banks of mountain streams, and goats graze between granite rock formations.
