Researchers show how an algorithm for filtering spam can learn to pick out, from hours of video footage, the full behavioral repertoire of tiny, pond-dwelling Hydra. By comparing Hydra’s behaviors to the firing of its neurons, the researchers hope to eventually understand how its nervous system, and that of more complex animals, works.

In a new study, Columbia researchers find that street trees with protective guards soaked up runoff water six times faster than trees without guards.
In a new study in Science, researchers predict a rising number of asylum seekers to the European Union as global temperatures increase.
Tufa Dinku, a researcher at Columbia University's International Research Institute for Climate and Society, is working to fill Africa's climate-data gaps by combining satellite measurements with sparse on-the-ground weather-station data. Improved weather and climate forecasts can help farmers and epidemiologists increase crop yields and limit the spread of malaria and other infectious diseases.
New technology adapted to cheap DNA sequencers can rapidly identify people and cells from their DNA.

New technology adapted to cheap DNA sequencers can rapidly identify people and cells from their DNA. Here, researcher Sophie Zaaijer demonstrates from a NYC rooftop how easy DNA-authentication can be.

Researchers have developed a method to quickly and accurately identify people and cell lines from their DNA. The technology, described in the latest issue of eLife, has a wide range of applications, but its most immediate use could be to flag mislabeled or contaminated cell lines in cancer experiments.
