More Dec 27 2019 | By Allison Elliott 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.

Climate change and the challenge of long-term thinking | Adam Sobel | TEDxBroadway Runtime 10:45 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.

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.” Revolutionary Ultra-thin “Meta-lens” Technology Runtime 2:27 Broadband imaging in the near-infrared using a single meta-lens, showing the ability of the lens in correcting chromatic aberrations, and manufacturing of meta-lenses using planar fabrication techniques similar to those used in the integrated circuits industry. The Nanostructure Problem: Simon Billinge at Brookhaven National Labs Runtime 3:17 In order to see inside nanomaterials and learn how nanoparticles evolve, Simon Billinge, applies the world’s newest and brightest synchrotron light source—the National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy’s Brookhaven National LaboratoryA physicist with a joint position at Columbia University's School of Engineering and Applied Science and Brookhaven, Billinge gives us a tour of his workflow at NSLS-II. Yuan Yang Flexible Battery, Smart Watch, and Meter Runtime 2:07 Video demonstrating flexibility of Yang's lithium-ion battery powering a smart watch, in flat, flexed, and twisted configurations. Nuclear Fusion Energy: The Race to Create a Star on Earth Runtime 11:06 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.Check out CNET's channel for more: http://bit.ly/2gpeXdrSubscribe to MOTHERBOARD: http://bit.ly/Subscribe-To-MOTHERBOARDFollow MOTHERBOARDFacebook: http://www.facebook.com/motherboardtvTwitter: http://twitter.com/motherboardTumblr: http://motherboardtv.tumblr.com/Instagram: http://instagram.com/motherboardtvMore videos from the VICE network: https://www.fb.com/vicevideo Adam Sobel: Preparing for the Next Big Storm Runtime 5:36 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.(Photos: NOAA, NASA, U.S. Navy, U.S. Coast Guard, NYC MTA, John Allen, Creative Commons) Spinning Out, In Control (Panel, Full Video) | #StartupColumbia 2018 Runtime 50:04 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. Transmission Microscopy Lab: probing the structure of materials at nanoscales Runtime 2:23 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. Can clouds buy us more time to solve climate change? | Kate Marvel Runtime 13:08 Climate change is real, case closed. But there's still a lot we don't understand about it, and the more we know the better chance we have to slow it down. One still-unknown factor: How might clouds play a part? There's a small hope that they could buy us some time to fix things ... or they could make global warming worse. Climate scientist Kate Marvel takes us through the science of clouds and what it might take for Earth to break its own fever.Check out more TED talks: http://www.ted.comThe TED Talks channel features the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less).

Recorded Thu Feb 16, 2017How 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. 150th Anniversary Symposium: Columbia's Engineering Renaissance. Fluids. 12 Runtime 5:15 C. K.
