In this lecture, an anthropologist reveals how a seven-million-year-old skull found in Chad, Africa in the summer of 2002, caused many long-held scientific beliefs to be called into question. Fossils are the keys scientists use to unlock the mysteries of human origins. Skull fossils in particular hold a wealth of information. By examining facial features and skull traits of a creature, researchers ... Full description.

This audio lecture features scientists who examine the unusually high mortality rate of sugar maple and red spruce trees as a means of illuminating broader issues affecting forests of the Northeastern United States. The scientists discuss the decline of these species and whether it is a local phenomenon, or if it is indicative of larger regional-scale disturbances. Data is presented from study stands ...

This guided tour of the dinosaur known as Dilophosaurus is narrated by the discoverer of Dilophosaurus, Sam Welles, formerly a professor at the University of California Museum of Paleontology (UCMP). Links lead to Dr. Wells' description of the discovery, as well as the morphology and habits of the creature. He also compares and contrasts the real animal with the one shown in the movie Jurassic Park. ... Full description.

This video lecture explores the chemistry of the hordes of molecules in the interstellar medium revealed by radioastronomical observations of our galaxy. Extremely fast reactions result in the high abundance of complex organic compounds in the space between the stars. The chemistry of the interstellar medium illustrates that complex synthesis occurs under totally abiotic conditions. The specific reactions ... Full description.

This lecture explains research on the shark species who migrate north to Massachusetts as the ocean waters warm in May and June. Among the species are oceanic sharks such as the blue, mako or basking sharks; coastal species such as sandbar sharks, spiny and smooth dogfish; or tropical species such as tiger and hammerhead sharks; and the porbeagle shark, the only species found year-round in Massachusetts ...

In this lecture, an ecologist shares photos and video clips as he explains biological and geological changes he has observed at an undersea volcanic ridge 2,500 meters deep in the Pacific Ocean. The ongoing studies from 1991 of this unique natural deep-sea laboratory are dramatically altering views of the rates at which many biological and geological processes are occurring on the face of the planet. ...
