View the videos At age 13, Wayne Maddison spied the metallic-green jaws of a spider marooned on a raft of vegetation floating on Lake Ontario. He rescued the young creature, and ultimately made a pet of her and one of her young. Along the way, he fell in love with their family — jumping spiders. That intense affection has never waned. Forty years later, Maddison, now scientific codirector of the Beaty Biodiversity Museum in Vancouver, is among the foremost authorities on these stealthy pouncers of the arachnid world. Last year, Maddison tallied some 175 distinct jumping spider species as h... (p. 32)Published: October 20, 2012; Vol.182 #8

Most people would never equate downing a well-dressed salad or a fried chicken thigh with toking a joint of marijuana. But to Joseph Hibbeln of the National Institutes of Health, the comparison isn’t a big stretch. New animal experiments by Hibbeln and his colleagues have recently shown that the body uses a major constituent in most vegetable oils to make its own versions of the psychoactive ingredient in marijuana. Called endocannabinoids, these natural compounds play a role in heightening appetite. So overproducing them unnecessarily boosts hunger, similarly to how pot triggers the munchi...

It took one of the biggest machines in the world to find one of the smallest particles. Buried beneath the grassy countryside near Geneva, Switzerland, is a giant tunnel in the shape of a circle 8.6 kilometers (about 5 miles) across. There, scientists recently discovered a particle they had been hunting for a very long time: something called the Higgs boson. It helps explain how everything in the universe has developed mass.Visit the new Science News for Kids website and read the full story: Higgs — at last!Published: 2012-09-07 12:42:12

Her name is P-52. It doesn’t sound all that special. But she broke records earlier this year as the largest wild Burmese python ever found in the United States. At 17.7 feet long (5.36 meters), she weighed a whopping 164 pounds (74.4 kilograms). When researchers at the Florida Museum of Natural History opened her up earlier this month, they found 87 eggs — also a record. Although Burmese pythons are native to Southeast Asia, thousands are now born in the wilds of Florida each year.

A little more than 43 years ago, an American astronaut climbed down the ladder of his lunar landing module — the Eagle — and became the first human to touch the moon’s surface. As he steadied himself, he said: “That’s one small step for a man, one giant leap for mankind.” Around the globe, an estimated 530 million people watched on their televisions as Neil Armstrong uttered those now-famous words. On August 25, this American hero died at age 82. Armstrong and fellow moonwalker Edwin “Buzz” Aldrin briefly became the first ambassadors to another world on July 20, 1969.

David Hone of the University of Bristol in England has made a career of studying pterosaurs — flying reptiles from 100 million years ago or more. Several years back, while working in southern Germany, he visited the local Solnhofen Museum along with a lot of other pterosaur experts. As they peered into a glass museum case that held a sandy-colored, fossil-bearing rock, he recalls the scientists saying something like: “How lovely, another Rhamphorhynchus.” The fossil was nice, but tiny — and just one of some 120 or so specimens of this pterosaur from about 150 million years ago.

On August 5, after a journey lasting more than 8 months, a carlike rover carefully settled down onto the surface of Mars. The vehicle is basically a science lab. Its mission: to search for evidence that the Red Planet might once have hosted life — even if the organisms were only one-celled microbes. The first stage of this mission — the landing — is “an amazing achievement,” observes Charles Bolden. He runs the National Aeronautics and Space Administration, or NASA, which built and delivered the vehicle to Mars. Several years ago, NASA scientists began considering the best place fo...Published: 2012-08-23 11:12:42Found in: Science News For Kids
