Protracted drought threatens California levees

Levee failures are most often associated with the onslaught of water from large storms, such as Hurricane Katrina, whose landfall in 2005 caused more than 50 floodwalls and levees around New Orleans to fail.

But the lack of water can also weaken these critical earthen structures, according to recent research presented last December at the fall meeting of the American Geophysical Union in San Francisco.

Down to Earth With: Glaciologist Ted Scambos

As a young boy, Ted Scambos was fascinated by space and technology, and spent many hours watching aircraft take off and land at the Air Force bases where his father, a pilot, was stationed. For his birthday or Christmas, he says he would often ask for a new telescope or a book about the planets. By sixth grade, Scambos had decided to become an astronomer. But by high school, his attention shifted from outer space to chemistry, and he set up an elaborate chemistry set in his parents’ basement. As Scambos’ interests evolved, he gradually realized that although astronomy and chemistry were both very hands-on disciplines at first, the deeper he delved, the more esoteric they became. Instead, he found himself drawn to geology, especially after discovering how much he enjoyed fieldwork.

Getting there and getting around Jordan

Jordan has two international airports: Amman and Aqaba. Amman’s Queen Alia International Airport is the main gateway, offering service to most major Middle Eastern and European cities and regular nonstop flights to New York, Chicago and Montreal. The airport is located 35 kilometers south of Amman; reach the city via express bus service or taxi. Taxis also serve Madaba, which is much smaller and closer to the airport. Madaba hotels will arrange airport pickup and King’s Highway transportation for you. The most convenient and flexible exploration option is with your own vehicle. Several rental agencies operate in Madaba, with more selection at the airport. Our vehicle was delivered to our Madaba hotel, allowing us to avoid city driving in Amman. Signs are generally in both Arabic and English.

Parasites of the Paleozoic

Parasitism — an ecological relationship in which one species benefits at the expense of its host — is common among living organisms, but as most parasites are soft-bodied, it’s rare to find them preserved in the fossil record. Two recent discoveries, however, have lengthened the short list of ancient parasites
