Whilebiotech companies are trying to extol the many benefits of using GM crops tomany farmers, there seems to be a growing concern of its long term effects andfor what it may possibly do to the environment at large. For example,scientists have recently conducted an insect resistance review of insects to Bttoxins that are inserted into GM crops like Bt cotton and Bt corn.While GM companies have promised lesser pesti...

Many of you may know that Discover is not only a web site thathosts a diverse collection of entertaining blogs, but also publishes a monthly“magazine” printed on paper. Wild, right? Just ask this baby, who can tell youthat a magazine is kind of broken when compared to an iPad.Continue reading →...
This Is What It Looks Like When Black Holes Collide
October 18th, 2011 — Physics Tagged Black, Collide, Holes, Like, looks, This
A new visualization method shows the twists in space-time, called vortices,thrown off after two block holes merge. Theoretical physicist and black holeguru Kip Thorne says he gets about one greatidea every 10 years. He recently unveiled what he considers the latest of theseonce-in-a-decade doozies: a new way tovisualize how black holes stretch and bend the fabric of space-time…Continue reading →...
Guest Post: Lisa Randall on Writing Knocking on Heaven’s Door | Cosmic Variance
October 17th, 2011 — Physics Tagged Cosmic, Door, Guest, Heaven’s, Knocking, LISA, Post, Randall, Variance, Writing
Lisa Randallis a friend and collaborator, as well as a science superstar.She is one of the most highly cited physicists of all time, for a variety ofcontributions to field theory and particle physics, especially her work withRaman Sundrum on warped extradimensions. Her first book, Warped Passages, was a major success,which naturally raises the question of what one does next. (Besides writing papers, I mean.)Continu...
Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth
October 16th, 2011 — Physics Tagged 100x, Bandwidth, could, Give, more, Radio, Twisting, waves, Wireless
As more people stream video to their mobile devices, wireless bandwidth isbecoming an increasingly precious commodity. Data traffic increased 8,000percent in the past four years on AT&T’s network alone. In trying to avoidwhat the Federal Communications Commission calls a “looming spectrum crisis,”telecommunications companies are lobbying the government to assign them morespectrum space in the 300- to 3,00...
CERN Lectures on Cosmology and Particle Physics | Cosmic Variance
October 15th, 2011 — Physics Tagged CERN, Cosmic, Cosmology, Lectures, particle, Physics, Variance
Here’s a blast from the somewhat-recent past: a set of five lectures I gaveat CERN in 2005. It looks like the quality of the recording is pretty good.The first lecture was an overview at a colloquium level; i.e. meant forphysicists, but not necessarily with any knowledge of cosmology. The next fourare blackboard talks with a greater focus; they try to bring people up to speedon the basic tools you need to think a...

As the 2012 presidential race ramps up, campaigns are courting voters notonly at the traditional county fairs and town hall meetings, but online—andgenerating, in the process, an enormous amount of data about who potentialvoters are and what they want. At CNN.com, Micah Sifry—anexpert on the intersection of technology and politics—delvesin the Obama team’s extensive efforts to mine and manage the data&...
