If you go into the backyard after dusk this time of year, you may get treated to the greenish yellow flashes of the firefly. But what do the flashes mean?

"We are looking at the silent love songs of male fireflies," explained Sara Lewis, Professor of Evolutionary and Behavioral Ecology at Tufts University

What Wild Bees Can Teach Us

Since honeybees are the original “hive mind,” what can we learn from these social insects?

Thomas Seeley is the Horace White Professor in Biology at Cornell University. He is based in the Department of Neurobiology and Behavior, where he teaches courses on animal behavior and does research on the behavior and social life of honey bees. He is the author of Honeybee Ecology (1985), The Wisdom of the Hive (1995), and Honeybee Democracy (2010).

Deep-sea hydrothermal vents were discovered forty years ago, surprising scientists who thought the deep sea floor was devoid of life. Today, we know that there are many different ecosystems on the seafloor, all based on microbes who make energy from chemicals, rather than light.

We speak with Stefan Sievert and Lauren Mullineaux of Woods Hole Oceanographic Institution about what we're still learning about hydrothermal vents.

Death may be inevitable. But what about aging? If we could figure out what biological switches get flipped to start the process of decline, could we reverse it? Even prevent it?
