Science Night 3/19

Wednesday is Science Night on KLRU!

Nature Frogs: The Thin Green Line at 7 pm
It is the greatest mass extinction since the dinosaurs. Population by population, species by species, amphibians are vanishing off the face of the Earth. Despite international alarm and scientists scrambling for answers, the steady hemorrhaging of amphibians continues like a leaky faucet that cannot be fixed or a wound that will not heal. Large-scale die-offs of frogs around the world have prompted scientists to take desperate measures to try to save those they can.

NOVA Venom: Nature’s Killer at 8 pm
Venom scientists are in a race against time. Inside the bodies of many creatures, evolution has produced extreme toxic cocktails, all designed for one reason: to kill. It took millions of years to perfect these ultimate brews of proteins and peptides and we have only just begun to discover their potential. Now, the race is on to collect and study them before the animals that produce them disappear. But how does venom do its deadly work? NOVA reveals how venom causes the body to shut down, arteries to bleed uncontrollably and limbs to go black and die. But nature’s most destructive and extreme poisons could contain the building blocks for a new generation of advanced drugs that could treat heart attack, stroke, diabetes, obesity and cancer. VENOM follows scientists on their expeditions to track down and capture the planet’s most deadly creatures, risking life and limb just to tease out milligrams of venom and get it back to the lab. Find out how nature’s deadliest cocktails could be medicine’s brightest new hope.

Skeletons Of The Sahara at 9 pm
This film tells the story of scientist Paul Sereno’s amazing discovery of a prehistoric human burial ground in the middle of one of the world’s most forbidding desert. Like many great scientific discoveries, this one happens by accident. Sereno, one of the world’s leading experts in finding fossils of dinosaurs and ancient crocodiles, is on an expedition to Niger, in Saharan Africa. Six weeks into a three-month journey, Sereno’s team makes an unexpected discovery. They find bones all right, but these bones don’t belong to prehistoric beasts — they are human bones, the last remnants of a people who lived from 10,000 to 5,000 years ago when this now forbidding landscape was a thriving culture on the edge of a vast lake. Sereno’s team counts the remains of dozens within a few minutes. “Skeletons of the Sahara” tells the story of this find and what it reveals to us about two civilizations that once thrived in what is now the world’s largest desert.
