Archaeology: How long did it take to build Serpent Mound?

Whenever I give presentations about the amazing earthworks built by Ohio’s ancient American Indian cultures, a frequently asked question is, “How long did it take to build them?”In a new article on architectural energetics, Jamie Davis, Jarrod Burks and Elliot Abrams show how to answer this question using Ohio’s Serpent Mound as an example.As a first step, they created a 3D model of the Serpent using drone imagery and gauged the mound’s volume, arriving at […]

New technology maps threatened coral reefs

Coral reefs make up just 1% of the ocean floor yet they are home to 25% of the world’s marine fish, a growing source of protein for people. But reefs are imperiled by a range of threats including warming waters, acidifying seas, destructive fishing methods, and agricultural and other runoff.Moreover, scientists have only a rough idea of the extent of reefs worldwide; a reef thought to be 1,000 acres might be 1,500 or just 500. Of the reefs that have been accurately mapped, […]

Self-checkout registers, usually the speediest of options, also weren’t working at times.Target temporarily […]

Ohio State researchers' biodegradable plastic alternative being honed for marketplace

Ohio State researchers have developed a sustainable alternative to plastic, but it might be some time before it can be used in everyday products.Yael Vodovotz, an OSU professor and researcher, and her team have been working on the plastic for more than 13 years and said her team is now testing ways to make it more recyclable and biodegradable.“Unfortunately, only about 8% of the total recyclable material is actually recycled,” Vodovotz said. “It’s a […]

Delaware Bay crab hunting puts migratory shorebirds at risk

REEDS BEACH, N.J. — On a recent spring day at this remote beach, hundreds of shorebirds flapped frantically beneath a net trapping them on the sand. Dozens of volunteers rushed to disentangle the birds and place them gently in covered crates.On a nearby sand dune, teams of scientists and volunteers attached metal leg bands, plastic tags and tiny radio transmitters to birds of three species. They were weighed and measured, and then released.The operation is part of an […]

Geology: Ohio's 200-pound, aquatic beaver lost to time

Ice Age Ohio would have been a great place to go on safari. You might have seen two kinds of elephants, mammoths and mastodons, the latter quite common and the former rather rare. You might have seen musk oxen that looked like goats but were the size of bison, which you also would have seen, including a species with horns that spanned 6 feet.Peccaries, pig-like animals closely related to the modern javelina of the American Southwest, would have been common. The stag-moose, looking […]
