Gardeners making their rounds through Barcelona’s Parc del Centre del Poblenou these days are as likely to carry tablets as trowels. The city recently moved 178 of its irrigation points to an Internet-controlled system. While it is handy to manage watering at the keyboard instead of turning a knob on a pipe, much of the advantage is in the data that the new system sends back to a central software system the city has built.

Men died in gun battles over the installation of windmills in the state of Oaxaca, Mexico, three years ago. Opponents argued that energy companies misled them and that community leaders rented out collective lands without consulting everyone they should have. Today, protests continue, but the growth of wind farms and other renewables seems assured: Mexico boasts almost 2 gigawatts of installed wind power capacity and plans to install perhaps another 12 GW by 2022. All that clean energy is a big change for this country, which is the world’s ninth-biggest oil producer and perhaps the 11th-biggest emitter of carbon dioxide. Continue reading
On a recent visit to Crystal Ice Cave in Idaho, climate and cave researchers had to wade through frigid, knee-deep water to reach the ice formations that give the cave its name. Cavers are good-humored about the hardships of underground exploration, but this water was chilling for more than one reason: it was carrying away some of the very clues they had come to study.
Ice is an invaluable source of information about the earth’s past. Pollen trapped in ice from polar ice caps and mountaintop glaciers documents plant life up to 1.5 million years ago, and gas bubbles and water isotopes reveal glimpses of ancient temperatures.
Polar ice samples cannot necessarily reveal what the climate was like in, say, New Mexico or other temperate regions, however. So a decade ago a small group of researchers began meeting to discuss the potential of cave ice, some of which is more than 3,000 years old. Since then, studies have confirmed that cave ice can illuminate some questions about how lower altitudes and latitudes responded to climate swings. But by this summer, when the scientists found themselves wading through the meltwater in Crystal Ice Cave during their biennial workshop, the main question had changed from what the ice could tell them to how to retrieve enough before it disappeared.
Thus far researchers have not won much funding for long-term studies of ice caves. Part of the reason is that obtaining a sample is a massive, expensive effort, requiring intense drilling, helicopters and refrigerated vans. And geochemist Zoltán Kern of the Hungarian Academy of Sciences in Budapest notes that he understands funders’ qualms because scientists have not yet figured out how to convert complicated cave ice data into tidy climate records. But this much is clear, says George Veni, director of the National Cave and Karst Research Institute in Carlsbad, N.M.: before the ice melts, “the main thing is to try and collect as much of it as possible.”
A program designed to boost investments in the scientific infrastructure of Europe’s lagging regions by pairing them with elite institutes elsewhere on the continent has proved unexpectedly popular. The European Commission has received 169 scientific business plans for the scheme, dubbed Teaming, and may be able to advance only 16% of the proposals to the next round of the competition. The commission will start reviewing the proposals in Brussels next week.
“We were delighted,” says commission spokesman Michael Jennings. “The response exceeded our expectations.” It also triggered an automatic 20% boost to the evaluation budget, according to an internal commission document obtained by ScienceInsider. Continue reading
