The wings of Lepidoptera contain a matrix of living cells whose functioning requires appropriate temperatures. However, given their small thermal capacity, wings can overheat rapidly in the sun. Here we analyze butterfly wings across a wide range of simulated environmental conditions, and find that regions containing living cells are maintained at cooler temperatures in a manner that is largely unaffected by visible color patterns. Diverse scale nanostructures and non-uniform cuticle thicknesses create a heterogeneous distribution of radiative cooling that selectively reduces the temperature of living structures such as wing veins and androconial organs.

Columbia Engineering professor Chris Wiggins and Columbia School of Social Work professor Courtney Cogburn explore the promise and pitfalls of using data to understand the world — and to change it.

Two professors, two fields, two schools. A data scientist and applied mathematician teaching with an expert on the history of science and technology. One class, one book, one vision. We went behind the scenes with Columbia's two professors for a brief exchange on their book "How Data Happened" which emerged from their class "Data: Past, Present, and Future."

Researchers have developed a new kind of "camera" that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The new method doesn't work like a conventional camera--it uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.

Adam Sobel doesn't want to prove that climate change is real. If you don't believe yet, he's confident you will eventually. Instead, what he wants to do is help our decision making about long-term events with future consequences to be better. He talks about climate change and how it has already and will continue to affect New York City, and how everyone should be thinking differently. Adam Sobel is a professor at Columbia University’s Lamont-Doherty Earth Observatory and Fu Foundation School of Engineering and Applied Sciences. He is an atmospheric scientist who specializes in the dynamics of climate and weather, particularly in the tropics, on time scales of days to decades. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Read the full interview in Columbia Engineering magazine. After almost a decade of long-distance collaborations, Keren Bergman, Michal Lipson, and Alex Gaeta are working together in one place, here at Columbia Engineering. Lipson and Gaeta joined the School this summer as the Eugene Higgins Professor in Electrical Engineering (EE) and the David M. Rickey Professor of Applied Physics and of Materials Science, respectively. And now, together with Bergman, who is the Charles Batchelor Professor and EE chair, the trio is set to break new ground in nanophotonics, or, as Lipson, a preeminent leader in nanophotonic fabrication, puts it, “optics on a very, very small scale.”

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy. We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

Superstorm Sandy was a wake-up call for a lot of people in New York City, including Adam Sobel, who’s spent more than two decades studying the physics of weather and climate. He spent a lot of time talking to the media about what was happening, and why. He says the intense public interest made clear to him the need to find ways to apply the esoteric physics of atmosphere and oceans so we can be better prepared for the next extreme event. Sobel is a research scientist and professor in the Department of Applied Physics and Applied Mathematics, the Department of Earth and Environmental Sciences and the Lamont-Doherty Earth Observatory. He directs the Columbia Initiative on Extreme Weather and Climate. In this latest in our video series, Sobel talks about the hard work of predicting extreme and rare weather events, and how he came to study in this field.

Sponsored by Columbia's Women Inventors Network and by Women in Science @ Columbia, this discussion takes a deep dive into the tale of three scientists' journey from innovation to spinout and what life is like at the intersection of university research and the commercial sector.

Materials science pioneer Katayun Barmak takes you behind the scenes at Columbia Nano Initiative’s new Electron Microscopy lab where researchers probe the nature of materials at the nanoscale.

Chris Wiggins is an associate professor of applied mathematics at Columbia University and co-founder of hackNY. He is a member of the faculty in the School of Engineering and Applied Science, and is a founding member of both the Institute for Data Sciences and Engineering, and the Department of Systems Biology. His research is at the intersection of data science and the natural sciences, particularly biology. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Recorded Thu Feb 16, 2017 How does climate change influence extreme weather events? Are they increasing in frequency or intensity? When a particular event happens, can we say with any justification that climate change played a role, or that it didn’t? How does the answer differ depending on which kind of event we are talking about – heat waves, floods, droughts, hurricanes, or tornadoes? I will explain what we know and don’t know, based on the latest scientific research on these topics.
