A Q&A piece on the National Oceanic and Atmospheric Administration begins with this incredibly disconcerting sentence: "During each hurricane season, there always appear suggestions that one should simply use nuclear weapons to try and destroy the storms."
Really? Seriously, America?
Anyway, the entire piece ends up being pretty fascinating, as research meteorologist Chris Landsea explains why nuking a hurricane would be a bad idea ... besides, you know, the obvious reasons.
... an explosive, even a nuclear explosive, produces a shock wave, or pulse of high pressure, that propagates away from the site of the explosion somewhat faster than the speed of sound. Such an event doesn't raise the barometric pressure after the shock has passed because barometric pressure in the atmosphere reflects the weight of the air above the ground. For normal atmospheric pressure, there are about ten metric tons (1000 kilograms per ton) of air bearing down on each square meter of surface. In the strongest hurricanes there are nine. To change a Category 5 hurricane into a Category 2 hurricane you would have to add about a half ton of air for each square meter inside the eye, or a total of a bit more than half a billion (500,000,000) tons for a 20 km radius eye. It's difficult to envision a practical way of moving that much air around.
Attacking weak tropical waves or depressions before they have a chance to grow into hurricanes isn't promising either. About 80 of these disturbances form every year in the Atlantic basin, but only about 5 become hurricanes in a typical year. There is no way to tell in advance which ones will develop. If the energy released in a tropical disturbance were only 10% of that released in a hurricane, it's still a lot of power, so that the hurricane police would need to dim the whole world's lights many times a year.

When people hear voices others can’t, the prevailing scientific model describes this as psychosis due to brain abnormality, chemical imbalance, or other affliction. But scientists have now reliably induced auditory hallucinations in some people not diagnosed with psychosis.
Tiny micromotors about the width of a human hair traveled through a mouse’s stomach delivering antibiotics to treat a stomach ulcer. The motors are powered by bubbles. According to the researchers from the University of California San Diego, the microrobot-based treatment proved more effective than regular doses of the medicine. From New Scientist: The tiny […]
In 1971, astronomer Frank Drake, the father of the search for extraterrestrial intelligence, drew a map pinpointing Earth in our galaxy. That diagram, a “pulsar map,” was etched on a plaque designed by Frank and Carl Sagan and first carried into space in 1972 by the Pioneer 10 and 11 spacecraft. In 1977, the pulsar […]
