Sounding Out Earth's Hum

Scientists are working to isolate and identify the various sources and mechanisms, beyond earthquakes, that vibrate the solid earth. The search has led them offshore to investigate how wind and waves and the seafloor interact to produce a symphony of sound that humans can’t hear.

Redefining Dinosaurs: Paleontologists are Shaking the Dinosaur Family Tree to its Roots

A radical reconfiguration of the classification of dinosaurs challenges an orthodoxy built on roughly a century and a half of research. But many paleontologists are not ready to accept such a big shift in our understanding of dinosaur evolutionary history.

Revealing the ghosts of glaciers past

On the ground, it’s hard to fathom the effects that glaciers once had on the now nearly ice-free Rocky Mountains, but from the air, the landscape is clearly haunted by the ghosts of glaciers past. In 2015, pilot and photographer Garrett Fisher set out in his antique 1949 Piper Cub aircraft to photograph all the remaining glaciers in the American Rockies.

Getting There and Getting Around Washington, D.C.

Washington, D.C., is served by three major airports: Ronald Reagan National Airport (DCA), Dulles International Airport (IAD) and Baltimore-Washington International Thurgood Marshall Airport (BWI). Reagan National is closest to downtown and is conveniently served by the Metro subway system. For those with window seats, flights in and out of DCA offer views of the Piedmont-Coastal Plain boundary along the Potomac River, in addition to exciting views of the National Mall. Dulles is a roughly 45-kilometer drive west of downtown D.C. in the exurbs of Northern Virginia. Window-seaters approaching IAD can spy quarries excavating rocks from the Culpeper Basin, as well as the Blue Ridge Mountains to the west. Flights to BWI, about 50 kilometers north of downtown D.C., offer views of the Chesapeake Bay and its tributaries draining the Coastal Plain. The airport is served by a commuter train that runs to Union Station, Washington’s downtown rail hub adjacent to the U.S. Capitol. Automobile traffic in and around the city is often heavy, and a cab or rideshare from IAD or BWI into the city can take upwards of an hour. Rail service aboard Amtrak into Union Station, which is on Metro’s Red Line, may be a convenient option for some visitors to D.C.

Getting There & Getting Getting Around Monti Sibillini National Park

For those traveling internationally by air to Italy to visit Monti Sibillini National Park, flying into Rome’s Leonardo da Vinci–Fiumicino Airport (FCO) is likely the best option. Florence is another option, but Rome is closer and hosts more flights. There are several routes into the park from different directions; all the entrance points on the western side of the park are a two-and-a-half- to three-hour drive east of Rome. Bus tour services run out of Rome, but the best way to reach the park is via rental car. Rental cars are plentiful, and the good news is that, unlike driving in some parts of Italy such as around Naples or in Sicily (which is not for the faint of heart), driving in the Apennines is much more like driving in the U.S. In this part of Italy, drivers are more courteous and generally adhere to road signage and lane guidelines. All countries have driving norms that are not immediately clear to foreign drivers, however. In Italy, to avoid scorn from your fellow drivers, it’s important to remember to never pass another car on the right. Italians consider it a severe breach of driving etiquette.

Going subterranean: Repurposed mines become innovative labs

Around the world, old mines are finding new life as underground research facilities, offering scientists unique ways to answer some of science’s biggest questions — from investigations of natural resources, seismic activity and carbon sequestration, to less obvious topics like biofuel development and how life began on Earth — and, maybe, on other planets as well.

Dutch Masters: The Netherlands exports flood-control expertise

Since the 13th century, the low-lying Netherlands has been developing innovative water management techniques and technologies, including recent projects like the Delta Works, the Zandmotor and Room for the River. Now, facing global sea-level rise, flood-prone coastal cities in the U.S., like New Orleans and New York, and elsewhere around the world, are calling on the Dutch to teach them how to hold back the sea.
