Oklahoma Ambulances Debut Sirens That You Can Feel 128

Posted by samzenpus on Thursday November 13, 2008 @02:35PM from the do-you-hear-something dept.

djupedal writes "Booming like a 1980s video game, the Howler can even make liquids ripple — Oklahoma's largest ambulance company will become the first ambulance service in the nation to outfit its entire fleet with new Howler sirens, designed to emit low-frequency tones that penetrate objects within 200 feet — such as cars — to alert drivers." This is all well and fine, but I wonder what they plan to do when their sirens call up one of the big worms from deep below?

Schneier Calls Quantum Cryptography Impressive But Pointless 233

KindMind writes "Bruce Schneier writes in Wired that quantum cryptography, while an awesome technology, is actually pointless (that is, of no commercial value). His point is that the science of cryptography is not the weak point, but the other links in the chain (like people, etc.) are where it breaks down."

Fungus Fire Spores With 180,000 G Acceleration 69

Posted by timothy on Tuesday October 07, 2008 @09:22AM from the easy-at-that-size dept.

Hugh Pickens writes "Although a variety of spore discharge processes have evolved among the fungi, those with the longest ranges are powered by hydrostatic pressure and include 'squirt guns' that are most common in the Ascomycota and Zygomycota. In these fungi, fluid-filled stalks that support single spores or spore-filled sporangia, or cells called asci that contain multiple spores, are pressurized by osmosis. Because spores are discharged at such high speeds, most of the information on launch processes from previous studies has been inferred from mathematical models and is subject to a number of errors, but now Nicholas Money, an expert on fungi at Miami University, has recorded the discharges with high-speed cameras at 250,000 frames-a-second and discovered that fungi fire their spores with accelerations up to 180,000 g, calling it 'the fastest flight in nature.' Money and his students, in a justified fit of ecstasy, have created a video of the first fungus opera."
