Go on tour to some of the spookiest and unexpected haunted places in cities like Washington, D.C. and London. Each program is based on historical ghost stories, meticulously researched, with interviews of historians and prominent folklorists.

Take a first look at how paleontologists categorize dinosaurs. Focusing on the major Saurischia group, identify the dinosaurs of the subgroup Theropoda, including carnivorous predators such as Tyrannosaurus rex and feathered dinosaurs. Continue with subgroups Prosauropoda, a diverse group of herbivores, and Sauropoda, containing the giant, long-necked herbivores such as the iconic Apatosaurus.

In this sexy, dark comedy, a Silver Lake mom puts her idyllic life in jeopardy when she tries to rescue a stripper by taking her in as a live-in nanny.

A veteran Detective Chief Inspector and his young Sergeant investigate murders around the regional community of Midsomer County.

Paleontologists now debate the traditional assumption that dinosaurs were cold-blooded. Learn the basics of thermoregulation in vertebrates. Then, consider the range of evidence, relating to body type and size, heart function, locomotion, brain capacity, and body temperature, that points to the possibility that dinosaurs were metabolically closer to birds and mammals than to modern reptiles.

The fossil record reveals fascinating details about dinosaurs' lifestyles, diets, and feeding strategies. See what dinosaur teeth and jaw structures tell us about how they ate and how they digested food, as in herbivores' scissor-like dental formations and beaks. Note also what fossilized dinosaur droppings show about their diets, and how dinosaurs themselves could be prey for other animals.

HOARDERS profiles adults who suffer from extreme hoarding, a mental disorder marked by an obsessive need to collect things, even if the items are worthless, hazardous, or unsanitary.

Investigate natural selection—how organisms evolve as they adapt to their environment. Also, study convergent evolution, where different species independently evolve similar features. Learn how scientists discern which organisms evolved from which, and which groups are most closely related. From this, grasp why birds, in fact, are dinosaurs, and why ancient swimming and flying reptiles are not.

Trace the history of extinction events across geological time, episodes of major climate change that wiped out vast numbers of animal and plant species. Then, investigate the extinction of the dinosaurs and other organisms in the late Cretaceous Period, and the environmental disturbances that caused it. Visualize the extent of the devastation and how surviving life forms were able to begin anew.
