A great many animals mimic the form, color, and movements of ants. Some gain protection from general predators that don’t eat ants, some are specialized ant predators who trick prey ants into coming closer, and others copy ants for reasons that aren’t well understood. This gallery showcases the diversity of mimics.

On June 5, 2012, several thousand castaways rode a massive boxcar-sized dock to landfall on Oregon’s Agate Beach, just north of Newport. A plaque on the side, written in Japanese, revealed an unprecedented journey: The dock had been unmoored from the Japanese coastal city of Misawa during the catastrophic tsunami on March 11, 2011.
The dock and its inhabitants — as many as a hundred species, including mollusks, anemones, sponges, oysters, crabs, barnacles, worms, sea stars, mussels and sea urchins — spent more than a year at sea, drifting 8,000 kilometers across the Pacific Ocean. Within hours of the dock’s discovery, marine biologists from Oregon State University’s Hatfield Marine Science Center were on the scene, identifying species and raising red flags.
“Very quickly we realized we were dealing with a cast of very bad characters,” says John Chapman, an Oregon State University marine biologist who was among the first on the scene. And it was not a small cast: More than two tons of living organisms would eventually be removed from the 20-meter by 6-meter by 2-meter dock. “This was essentially an intact subtidal community of Asian species, aliens fully capable of reproducing, colonizing and invading the Oregon coast,” Chapman says.
“The image shows a single thread of double-stranded DNA suspended on a bed of nanoscopic silicon pillars.”
Cummingtonite is a metamorphic amphibole with the chemical composition (Mg,Fe)7Si8O22(OH)2, magnesium iron silicate hydroxide….Cummingtonite was first discovered in 1824 near the town of Cummington, Massachusetts, and it is from this town that the mineral takes its name.
Glow in the dark cats could help find cure for AIDS
A new genetic-engineering technique that makes cats glow in the dark could help scientists understand HIV and AIDS as well as feline immunodeficiency virus. So far, the researchers have created three genetically engineered kittens that can glow green and pass this gene onto their offspring.
