Mon 5/06: very brief KQED DT9 OTA outage
(DT9.1, 9.2, 9.3) This morning we had a very brief outage of our over the air (OTA) coverage for KQED 9.1/9.2/9.3, which lasted apx 4 minutes. Most tuners will have found the channel again as soon as service was restored, but some may need to be rescanned for channel 9. This outage did not affect [...]

Decoding Neanderthals (Episode #4002H)
KQED 9: Wed, May 15, 2013 -- 9:00 PM
Over 60,000 years ago, the first modern humans --people physically identical to us today -- left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age. But when they arrived, they were not alone: the stocky, powerfully built Neanderthals had already been living there for hundred of thousands of years. So what happened when the first modern humans encountered the Neanderthals? Did we make love or war? That question has tantalized generations of scholars and seized the popular imagination. Then, in 2010, a team led by geneticist Svante Paabo announced stunning news. Not only had they reconstructed much of the Neanderthal genome -- an extraordinary technical feat that would have seemed impossible only a decade ago -- but their analysis showed that "we" modern humans had interbred with Neanderthals, leaving a small but consistent signature of Neanderthal genes behind in everyone outside Africa today.

Ancient Computer (Episode #4007H)
KQED Plus: Tue, May 14, 2013 -- 8:00 PM
An unpromising lump of metal found in a 2000-year-old shipwreck turns out to be an extraordinary treasure: the world's first computer. Nova follows the ingenious detective work that painstakingly discovered the truth about the ancient Greek device: it was an astonishingly sophisticated astronomical calculator and eclipse predictor, unrivaled until the era of modern science and believed to be from the workshop of Archimedes.

Venom: Nature's Killer (Episode #3808H)
KQED Life: Thu, May 9, 2013 -- 8:00 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. This episode 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.

Meteor Strike (Episode #4013)
KQED World: Thu, May 9, 2013 -- 5:00 AM
A blinding streak of light screaming across the Russian sky, followed by a shuddering blast strong enough to damage buildings and send more than 1000 people to the hospital. On the morning of February 15th, a 7000 ton asteroid crashed into the Earth's atmosphere, exploded and fell to earth across a wide swath near the Ural mountains. According to NASA, the Siberian Meteor, which exploded with the power of 30 Hiroshima bombs, was the largest object to burst in the atmosphere since a 1908 event near Siberia's Tunguska river. That time there were few eyewitnesses and no record of the event except for thousands of acres of flattened trees. This time however the event was captured by countless digital dashboard cameras, which have lately become a common fixture in Russian autos and trucks.
Within days, armed with this unprecedented crowd-sourced material, Nova crews hit the ground in Russia along with impact scientists as they hunt for debris from the explosion and clues to the meteor's origin and makeup. To understand how lucky we were this time, we explore even greater explosions in the past, from Tunguska to the asteroid that extinguished the dinosaurs 65 million years ago. This episode puts it all together and asks: Is our solar system a deadly celestial shooting gallery - with Earth in the cross-hairs? What are the chances that another, even more massive asteroid is heading straight for us? Are we just years, months or days away from a total global reboot of civilization, or worse?

Australia's First 4 Billion Years: Strange Creatures (Episode #4012H)
KQED 9: Wed, May 1, 2013 -- 9:00 PM
Of all the continents on Earth, none preserves a more spectacular story of its origins than Australia. Nova's mini-series takes viewers on a rollicking adventure from the birth of the Earth to the emergence of the world we know today. With help from high-energy host and scientist Richard Smith, we meet titanic dinosaurs and giant kangaroos, sea monsters and prehistoric crustaceans, disappearing mountains and deadly asteroids. This is the untold story of the Land Down Under, the one island continent that has got it all.

Smartest Machine On Earth (Episode #3806H)
KQED Plus: Wed, May 1, 2013 -- 2:00 AM
What's so special about human intelligence and will scientists ever build a computer that rivals the flexibility and power of a human brain? Nova takes viewers inside an IBM lab where a crack team has been working for nearly three years to perfect a machine that can answer any question. The scientists hope their machine will be able to beat expert contestants in one of the USA's most challenging TV quiz shows -- Jeopardy, which has entertained viewers for over four decades. This program presents the exclusive inside story of how the IBM team developed the world's smartest computer from scratch. Now they're racing to finish it for a special Jeopardy airdate in February 2011. They've built an exact replica of the studio at its research lab near New York and invited past champions to compete against the machine, a big black box code - named Watson after IBM's founder, Thomas J. Watson. But will Watson be able to beat out its human competition?
