U.S. braces for ‘Swarmageddon’ as billions of cicadas expected to emerge after 17 years underground
America’s East Coast is bracing for a cacophonous summer as hordes of flying insects emerge for a once-in-a-generation phenomenon popularly known as “Swarmageddon”.
After 17 years underground growing from larva to bug, billions of cicadas are about to revel in the final four climactic weeks of their unusual life cycle.
At some point over the next few weeks, when the temperature at eight feet below ground reaches a steady 64F, the nymphs, as juvenile cicadas are called, will scramble out of the ground.
They will then embark on their noisy, short-lived adult life in pursuit of a mate. Males flex their tymbals, drum-like organs in their abdomens, making a distinctive clicking sound. Female cicadas answer by snapping their wings. (Scott Olson/Getty Images File)
things like this are why the west coast is the best coast….

Jet engines need cutting-edge materials that are strong, light and can withstand extreme heat. GE is developing a material that can handle high temperatures like ceramics can and is also as tough as metal. Here, a projectile fired at a sample of advanced ceramic composite tests the material’s ability to endure the strike.

Back in 2007, I had a patient who was uninsured with a strong family history of breast cancer. At the time, the only place you could get tested for BRCA1 and BRCA2 was this company called Myriad. They had a monopoly on the test. I thought the patient really needed to know her risk (which could be as high as 87% likelihood of getting breast or ovarian cancer). I called up Myriad and asked how much their test would cost a cash-paying patient. They said $4000. I asked if they had some sort of financial assistance programs. They said nope. Of course this made me angry.
And now it’s 2013. Back in January I joined 23andMe, spit in a cup and sent it off to them, and found that I have none of the three most popular BRCA mutations. And this only cost me $99 cash. So…in 5 years or so, the cost of understanding your risk went from $4000 for testing two genes to $99 for sequencing much of your DNA. And that’s a beautiful thing.
I applaud Angelina Jolie for being open and honest about her decision to have a double mastectomy to prevent breast cancer. Celebrities can shed a vital light on important and difficult issues to popularize. And she’s done a remarkable job, unlike Jenny McCarthy. By being science and data-driven, you can save lives. By being emotional and scientifically ignorant, you can take lives.

$99 is worth it to know.
