POPSNaturmobil: Cart runs on "horse power" "My friends and relatives thought of me as a somewhat eccentric half-mad inventor attempting the impossible," said Mirhejazi who has brought his invention to Dubai. Nevertheless, one friend was prepared to rustle up enough cash to put the project under starter’s orders. "It took me 26 months to build the vehicle in my workshop in Tehran. I got it patented by a special department in Iran after professors at universities there attested that it was a scientific invention."

POPSAnimal senses humans don't have You might think you're smart, but none of your senses rival the keenest abilities in the animal world. Animals see in the dark, sniff prey miles away, and detect electrical output from muscle twitches in hidden meals. Read on, so you don't become one of those meals.<<

POPSRaindrops on roses The team tried to replicate the effect.They put some polyvinyl alcohol onto rose petals and allowed it to set, then peeled off a thin plastic cast of the petal surface.This film had the same properties as the rose petal:the film could hold droplets of between 3-5 microlitres even when held upside down. It seems that the physical shape of the surface is much more important than any chemical properties of the material in creating 'stickiness',says Ronald Fearing, a biomimetic engineer at the University of California at Berkeley. For a rose, this stickiness might come in handy as reflective water drops that glisten in the Sun might attract pollinating insects. In the lab, such materials might be useful for 'lab on a chip' devices that need to hold and shunt around tiny quantities of liquid without leaking or being contaminated by nearby materials. "These findings present many interesting applications in microfluid handling," says Fearing.

POPSDigital Sound Separator The new tool promises to give musicians and producers powerful new ways to manipulate recordings both old and new.It might let studio engineers peer inside a chord-heavy rhythm-guitar part and nudge individual notes into tune. Or it could let them salvage unheard takes by classic musicians like Duke Ellington or Jimi Hendrix, left unreleased due to out-of-tune instruments or misplayed notes. It will certainly give musicians new ability to sculpt sound, such as prerecorded samples or loops, as if they were modeling clay.

POPSThe Origin of the Crossword Puzzle Crossword Casualties Some folks were driven over the edge by the craze. In 1924, a Chicago woman sued her husband for divorce, claiming "he was so engrossed in solving crosswords that he didn’t have time to work." The judge ordered the man to "limit himself to 3 puzzles a day and devote the rest of his time to domestic duties." In 1925, a New York Telephone Co. employee shot his wife when she wouldn’t help with a crossword puzzle. And in 1926, a Budapest man committed suicide, leaving an explanation in the form of a crossword puzzle. (No one could solve it.) Eventually, the craze died down. It took The New York Times to revive it. Today, The New York Times crossword puzzle is considered the puzzle of choice for hardcore addicts, but that hasn’t always been true. Believe it or not, the Times resisted crosswords for more than two decades.Here’s the story of how the newspaper changed its mind...<<
