AUSTIN, Texas — A trove of exceptionally preserved Jurassic marine fossils discovered in Canada, rare for recording soft-bodied species that normally don’t fossilize, is expanding scientists’ view of the rich marine life of the period. (more…)
By mimicking the bulging, bowl-shaped eyes possessed by dragonflies, praying mantises, houseflies and other insects, a team of researchers that includes a University of Colorado Boulder engineer has built an experimental digital camera that can take exceptionally wide-angle photos without distorting the image.
To create the innovative camera, which also allows for a practically infinite depth of field, the scientists used stretchable electronics and a pliable sheet of microlenses made from a material similar to that used for contact lenses. The researchers described the camera in an article published on May 1, 2013 in the journal Nature. (more…)
COLUMBUS, Ohio — Forget “slow and steady wins the race.” A new study shows that, at least sometimes, the best way to conserve energy and reach your destination on time is to alternate between walking and running—whether your goal is the bus stop or a marathon finish line.
In the January 30, 2013 issue of the Journal of the Royal Society Interface, researchers examined how people budget their time as they travel on foot to reach a destination at a particular appointed time. The study found that when people have neither too much time nor too little time to reach their destination, they naturally switch back and forth between walking and running, which turns out to be the best strategy for saving energy.
