Celebrating decades of groundbreaking exploration in East Africa, renowned paleoanthropologists Donald Johanson and Richard Leakey shared the stage at the American Museum of Natural History on May 5 to discuss the overwhelming evidence for evolution in the hominid fossil record and why understanding our evolutionary history is so important. The discussion, before a sold-out crowd in the Museum’s LeFrak Theater, was moderated by Dr. Sanjay Gupta, chief medical correspondent for CNN. The event was also live-streamed on amnh.org to a digital audience of several hundred viewers around the country.

Entomologist Gene Kritsky, author of The Quest for the Perfect Hive: A History of Innovation in Bee Culture, will join beekeepers Richard Blohm and Carl Flatow for a discussion about urban beekeeping at this month’s Adventures in the Global Kitchen on Wednesday, May 11. He recently answered some questions about apiculture.

What is the earliest historic record of beekeeping, and where did it originate?The earliest historic record of beekeeping is from the Fifth Dynasty of Ancient Egypt.  This relief, which is in the Neues Museum in Berlin, shows the taking of honey from horizontal hives, extracting the honey from the wax, and sealing in jars.

The oldest known beehives date from 900 BCE and were found in the ancient city of Rehov in Israel.

What significant innovation vastly improved beekeeping?

The most important innovation in beekeeping was the incorporation of the “bee space” in hive design. The “bee space” is the space that is too far apart for bees to glue shut, but too narrow for them to bridge with comb. This design permitted the development of a hive with moveable frames, which led to significant increases in honey production per hive.

In the world of cutting-edge robot design, scientists are looking to biology and nature for inspiration. In this podcast, join Professor Dennis Hong, director of the Robotics and Mechanisms Laboratory at Virginia Tech, as he describes some of his more fantastic robots. 

The talk was recorded at the Museum on April 6, 2011.

This spring, Director of the Carnegie Observatories Wendy Freedman spoke at the American Museum of Natural History’s Hayden Planetarium about astronomer Edwin Hubble’s discovery of the galaxies and the expansion of the universe, how astronomers measure vast distances, and how the Hubble Space Telescope is used to measure the size and age of the universe. Mike Shara, curator in the Department of Astrophysics, sat down with Freedman for an interview in the Hayden Planetarium to discuss the expansion of the universe, dark matter, and building the 25-meter telescope.
