Cretaceous collagen: Can molecular paleontology glean soft tissue from dinosaurs?

In 2005, a team of molecular paleontologists reported the discovery of soft tissue from a 68-million-year-old Tyrannosaurus rex femur. In the decade since that controversial find, evidence has mounted that dinosaur soft tissue — which could help paleontologists answer long-standing questions about dinosaur physiology — can be recovered.

Can preserved proteins reveal paint-by-numbers plumage?

Some of the most compelling dinosaur fossils are those found with clearly defined feathers. Feathers may seem fragile and unlikely to be preserved, but in fact they’re composed of durable keratin, one of the toughest natural proteins. Additionally, some fossil feathers unearthed are speckled with tiny black dots, which, according to different studies, could be remnants of either bacteria or melanosomes. Melanosomes are organelles that produce and store melanin, the main source of pigment in feathers. If melanosomes are indeed preserved in some ancient fossils, they could reveal information about dinosaur coloration and plumage — and represent further evidence of preserved proteins in dinosaurs.

Travels in Geology: Cones and craters in Flagstaff, Arizona

Few places in the country exhibit as many types of volcanic features — including jagged lava flows, crumbly cinder cones and the remnants of a towering stratovolcano — in as small an area as northern Arizona’s San Francisco Volcanic Field.

Cassini's legacy after two decades

Scientists on Earth have received the last submission from the Cassini spacecraft. It descended into Saturn’s atmosphere at 122,500 kilometers per hour, which caused it to melt, thereby ensuring that Saturn’s moons Titan and Enceladus would remain protected from possible contamination by any errant Earth microbes. Cassini scientists had considered other options for the spacecraft’s end, including leaving it to float endlessly in space or parking it in orbit around Saturn. But ultimately, they chose to have it descend into Saturn’s atmosphere after deciding the data that could be returned from the descent were more valuable than any further data it might obtain by remaining in space. Scientists will make discoveries from these data for decades to come.

Getting there and getting around Bolivia's Antiplano

Bolivia’s main gateway, El Alto International Airport (LPB), is located 13 kilometers southwest of the country’s capital, La Paz. It hosts regular, year-round flights to and from major destinations in South America, including Lima and Cuzco, Peru, Santiago, Chile, and Buenos Aires, Argentina, as well as connecting flights to Miami on American Airlines and Los Angeles, Washington, D.C. (Dulles) and Orlando, Fla., on Avianca. Several regional airlines, including Boliviana de Aviación (BoA) and Amaszonas, offer multiple flights daily from La Paz to Uyuni. The hour-long flight typically costs about $150 one way. We found the South American carriers to be extremely efficient; it’s important to arrive at the airport two hours in advance because the flights often depart early!

Getting there and getting around Austria's Salzkammergut

Salzburg boasts Austria’s second-busiest airport, with nonstop flights to cities throughout Europe and connecting flights to a number of North American gateways. Munich, Germany, just 145 kilometers and 1.5 hours away on the A8 autobahn, has direct flights from North America. Picking up a rental car is easy at either airport. Austria’s official language is German, but many Austrians are fluent in English. Road signs are in German but are easily followed by English speakers.

Burying the sky: Turning carbon dioxide into rock

At an Icelandic geothermal power plant, researchers are capturing carbon dioxide and burying it in basalt to keep the greenhouse gas out of the sky. But can this method be scaled up, and work elsewhere, to help meet global climate goals?

Getting there and getting around the Dead Sea rift

Most flights into Israel from the U.S. and Europe go through Ben Gurion International Airport (TLV), located 19 kilometers south of Tel Aviv. The most flexible and convenient option for getting to and from the airport and for exploring the region is to rent a vehicle; the airport and downtown Tel Aviv offer many rental options. Cars drive on the right, and road signs are marked in Hebrew and English. From the airport, the Dead Sea is about a three-hour drive (170 kilometers).
