Elephants in Thailand have a big unemployment problem. Long a revered creature in traditional Asian cultures and a critical beast of burden for Asian economies, the captive elephant is becoming obsolete. Its plight has only worsened since 1989, when Thailand banned all logging operations, a major employer of these animals. Luckily, the thousands of captive elephants in Thailand have never been selectively bred and remain genetically wild. Watch how local and international scientists are reintroducing Asian elephants to the forest and reestablishing herd structures in hopes of reverting them to their most noble occupation—living wild.
Although stem cells hold promise as direct therapy for human diseases, many researchers are even more enthusiastic about the opportunity to use stem cells to study disease fundamentals. Learn how clinicians and researchers are involving diabetes patients in the search for a cure by developing new stem cell lines from their DNA.

In 1980 an act of Congress set aside nearly 20 million acres of Alaska's North Slope tundra to create the Arctic National Wildlife Refuge (ANWR). Less than 100 miles from the refuge is Prudhoe Bay, North America's largest oil field. Spread across what was once part of the largest intact wilderness area in the United States, Prudhoe Bay and its neighboring oil fields account for approximately 25 percent of U.S. domestic oil production.
On July 4, 1999, a rare and terrifying storm swept through the Boundary Waters Canoe Area Wilderness in northern Minnesota. What began like a standard-issue thunderstorm soon turned strange and fierce, generating green clouds and strong winds reminiscent of a tornado. In fact, the storm was a cousin of the tornado: a derecho (pronounced "de-RAY-cho"), a type of storm so infrequent and fast-moving that only in recent years have meteorologists begun to understand how to recognize and forecast it
Once upon a time, back in the twentieth century, the weather was straightforward: it rained or snowed, skies were sunny or cloudy. However, in the twenty-first century—the era of globalization and digitalization—a whole new kind weather is critical to consider: space weather.
Space weather is direct product of our local star, the Sun. The Sun continuously sheds its skin, blowing a fierce wind of charged particles in all directions, including Earth's. From time to time, storms on the Sun's surface—solar flares, coronal mass ejections—toss off added masses of energy and ions. When that turbulence slams into Earth, it produces space weather. The consequences can be spectacular, from colorful auroras to satellite, power and communications failures.
Space weather isn't new: the Sun has buffeted Earth with solar particles since the planet first formed. What has changed is society. This feature reveals how our increasing use of satellite technology has made us vulnerable to solar storms, and how solar scientists—"space weathermen"—are learning how to predict and forecast the Sun's activity.

The Universe's oldest light is cosmologists' newest window to the past.
For centuries, a massive atmospheric system has regularly altered weather patterns, fishery production and animal migrations across the North Atlantic Ocean. At last, Earth scientists and climate modelers are beginning to understand how--and when - the North Atlantic Oscillation happens.
