Thank the Moon for Earth’s Lengthening Day

University of Wisconsin-Madison

A new study that reconstructs the deep history of our planet’s relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around its axis.

New Theory Finds “Traffic Jams” in Jet Stream Cause Abnormal Weather Patterns

University of Chicago

A study in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.

Research Suggests Sweet Potatoes Didn't Originate in the Americas

Indiana University

Sweet potatoes may seem as American as Thanksgiving, but scientists have long debated whether their plant family originated in the Old or New World. New research by an Indiana University paleobotanist suggests it originated in Asia, and much earlier than previously known.

Cloaking Devices -- It’s Not Just ‘Star Trek’ Anymore

Acoustical Society of America (ASA)

Scientists are now working to take cloaking devices from the dramatic realm of science fiction and make them real. Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the wave energy, concealing the object from the sound waves. During the 175th ASA Meeting, Hanford will describe the physics behind an underwater acoustic shield designed in her lab.
