Got a Cell Phone? Use It to HelpTrack Crickets in NYC


Scientists in New York City are asking all folks with a cell phone and a sharp ear to take part in an interesting, and some might say disgusting, survey. According to Wired, it's called the 'NYC Cricket Crawl,' and the goal is to get an idea of just how many crickets and katydids still live in the city. At least it's not a sewer rat survey, right?

The 'Cricket Crawl' is quick, simple, and best of all, doesn't cost a dime. Here's how it works: step outside your place in NYC on September 11th sometime between sunset and midnight, stay really quiet, and listen hard for the chirp of a cricket or katydid. Then let the scientists know what you heard one of two ways: ID the cricket yourself (after learning the different types of calls), and phone or text the results; or record the sounds with a phone or camera, and e-mail the files to the scientists.

With the help of these insect enthusiasts, scientists hope to discover that the Common True Katydid, which once thrived in NYC, still makes its home in the city. Whatever the results, the 'Cricket Crawl' could provide a model for future surveys. Grassroots work that takes advantage of cheap technology eases the financial burden, and these days, that counts for a whole lot. [From: Wired]

Pentagon Making Cyborg Crickets


Using animals as sentinels is nothing new, such as when miners used canaries to detect carbon monoxide and methane in coal mines. As the New Scientist reports, the Pentagon plans to use cyborg crickets for very much the same purpose, only for detecting chemical and biological agents on the battlefield. By equipping the crickets with small electronics to control their muscle movements, and hence the sounds created by their wing movements, a living communications network (OrthopterNets) can be created to relay specific warning signals when the cricket is in proximity of certain chemicals. Similarly, the equipment can be modified to detect human scents, possibly helping to locate survivors in earthquake rubble or other disasters.

Because they communicate using wing-beats, crickets, cicadas, and katydids are all possible subjects. The idea first came about when Ben Epstein of high-tech company OpCoast was visiting China and noticed how the cicada were changing their calls to each other. OpCoast was later awarded a six-month contract to develop a mobile communications network for insects by the Pentagon. If you find all of this hard to believe, check out the video above from New Scientist showcasing human-controlled moths and beetles. [From: New Scientist]

Scientists Create Mutant Bugs that Produce Crude Oil

Like the beginning of every great science fiction movie, experts claim that they've discovered a cure for our fuel-dependency woes that only requires an army of genetically modified bacteria... that eats wheat straw and excretes crude oil.

You read that right: Scientists have created bugs that are able to snack on woodchips or sugar cane and produce waste in the form of easily malleable oil. Not only are the buggers capable of creating a by-product that can quickly be refined into fuel for vehicles, but scientists say the process is carbon-negative -- it outputs less carbon than is required to produce it. Director of the project -- dubbed LS9 -- Greg Pal says that barrel prices could run as low as $50, and that the company plans to have a commercial facility producing the crude in 2011.

And as for the potential threat of world-destroying attack from the mutant bugs? Says Pal, "We're putting these bacteria in a very isolated container: Their entire universe is in that tank. When we're done with them, they're destroyed." Sure buddy -- but we're going to re-watch 'Them!' just in case. [Source: Times Online]
