Fog Catchers "If we can help generate alternative sustainable economic activities, we will be increasing the community’s chances for a viable livelihood in the face of climate change." Juan José RodríguezThe Nature Conservancy’s Coasts and Deserts coordinator by Marcela Torres Vea también en español Have you ever seen a desert turn into a lush green valley bursting with life? This is exactly what happens in the coastal deserts of Peru every year, when oasis-like pockets of vegetation, called lomas, bloom between July and November thanks to the moisture they capture from fog.
The 10 Best TED Talks of 2011 Watching videos online is usually considered fun, but generally a waste of time. Not so with TED videos, which are uniformly interesting, educational, inspiring, and enjoyable. If you haven't spent much time (or any) checking out TED videos, you should – and to help with that, I've compiled what seem to be the very best 10 TED videos of 2011. It was a grueling task, combing through the cream of the crop on the TED site, but somebody had to do it. Some of the talks may have been filmed prior to 2011 but all of the talks here were posted in 2011.
Six Things Education Can Learn From Neuroscience Neuroscience studies a very complex system: the brain. Much has been learned through formal research of the brain, especially due to the advent of brain imaging technologies which afford increased breadth of research using human subjects. That said, what we know remains very limited, given the complexities of both the organ and the practical application of research findings. However, we can point to six findings that give us new and profound insight into our grey matter. Clarity on Spirit Science (A MUST SEE!) There have been a lot of questions recently about Spirit Science and it’s evolution. What are we up to, where are we going. Some people had made up some ideas as well about Spirit Science becoming Cult-Like and a new Religion, which Jordan and I thought was ridiculous.
DNA Animations Animation Adenine (A), cytosine (C), guanine (G), and thymine (T) are the components of nucleic acid that make up DNA. In 1950, Erwin Chargaff published a paper stating that in the DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine.

100 Incredible Lectures from the World's Top Scientists Posted on Thursday June 18, 2009 by Staff Writers By Sarah Russel Unless you’re enrolled at one of the best online colleges or are an elite member of the science and engineering inner circle, you’re probably left out of most of the exciting research explored by the world’s greatest scientists. But thanks to the Internet and the generosity of many universities and online colleges, you’ve now got access to the cutting edge theories and projects that are changing the world in this list below. If you’re looking for even more amazing lectures, check out our updated list for 2012 with more talks from great minds. Smart materials get SMARTer Cambridge, Mass. – July 11, 2012 – Living organisms have developed sophisticated ways to maintain stability in a changing environment, withstanding fluctuations in temperature, pH, pressure, and the presence or absence of crucial molecules. The integration of similar features in artificial materials, however, has remained a challenge—until now. In the July 12 issue of Nature, a Harvard-led team of engineers presented a strategy for building self-thermoregulating nanomaterials that can, in principle, be tailored to maintain a set pH, pressure, or just about any other desired parameter by meeting the environmental changes with a compensatory chemical feedback response. Called SMARTS (Self-regulated Mechano-chemical Adaptively Reconfigurable Tunable System), this newly developed materials platform offers a customizable way to autonomously turn chemical reactions on and off and reproduce the type of dynamic self-powered feedback loops found in biological systems.
How Digital Detectives Deciphered Stuxnet, the Most Menacing Malware in History It was January 2010, and investigators with the International Atomic Energy Agency had just completed an inspection at the uranium enrichment plant outside Natanz in central Iran, when they realized that something was off within the cascade rooms where thousands of centrifuges were enriching uranium. Natanz technicians in white lab coats, gloves and blue booties were scurrying in and out of the “clean” cascade rooms, hauling out unwieldy centrifuges one by one, each sheathed in shiny silver cylindrical casings. Any time workers at the plant decommissioned damaged or otherwise unusable centrifuges, they were required to line them up for IAEA inspection to verify that no radioactive material was being smuggled out in the devices before they were removed.
