Birds fly with speed and grace. They build intricate nests. Birds are survivors. They live on every continent of the world. Humans learned to fly by copying birds. Today, many new discoveries come from the study of birds. Scientists, architects, doctors, and engineers learn from them.
Few species are as smart and playful as dolphins. These speedsters of the sea live in social groups. They have taught us many useful lessons about life in the ocean. With natural sonar, they can swim and hunt while blindfolded. Scientists study dolphins to learn more about intelligence in animals and in humans.
Plants can do amazing things. They grow in the most unlikely places. They soak up sunlight for energy, and use rain, wind, and animals to spread their seeds. Some plants lure insects for food. Others can self-clean. Humans have copied many clever plant tricks. Today, scientists are placing technology inside plants. The results are awesome.
Spiders may be creepy, but they know amazing tricks. Some species have learned to fly. Others like to hangout underwater. Spider silk is strong and flexible. Spiders use it for more than just webs. Scientists keep trying to mimic spider silk. Once they succeed, people will find many awesome uses.
Whales are the world's largest animals. They roam the ocean in search of food, calling to each other with song. Humans nearly hunted whales to extinction. Now we learn from them, making better wind turbines and water filters. Whales may also help with medicine and climate change. They are awesome.
Sharks are perfect predators. These toothy fish have super senses for finding prey. We fear sharks but we also learn from them. The study of shark skin has led to many new inventions. Some species can even glow in the dark. New undersea drones swim like sharks. More discoveries await in the awesome world of sharks.
No other conflict in history matches the sheer magnitude of World War II. Aggressive dictators employed their military forces throughout the globe, forcing peaceful nations to fight back with troops and tanks. Deadly submarines scoured the world's oceans for enemy ships. In the sky, bombers and fighter planes tangled for supremacy. Meanwhile, scientists raced to develop new weapons and technology. The conflict raged for six years, affecting nearly...
The air campaign that opened the Gulf War in January 1991 was one of the most stunning in history. For five weeks, American and other Coalition aircraft pounded enemy targets with 88,000 tons of bombs. Sorties-more than 100,000 of them-were launched from bases in Saudi Arabia, from aircraft carriers in the Persian Gulf and Red Sea, and even from bases in the United States. The skies over Iraq and Kuwait were filled with a dizzying array of new and...
