As the Science Guy, television’s Bill Nye inspired a generation of children to love science as much as he does. But these days, he’s speaking to a new audience. "Nowadays I’m talking to adults," says Nye, "and I’m not mincing words. The climate is changing, it’s our fault, and we’ve gotta get to work on this!"    Join us for a conversation about climate science, climate denial and how to save the planet.

Unraveling the Genetics of Cannabis

May 8, 2017
Phylos Bioscience

Cannabis has been cultivated and used by humankind for centuries. Now the industry’s challenge is understanding and applying that history.

Cannabis arrived in North America from at least two different directions, but how that evolved into the plants that grow here today is not yet clear, says Phylos Biosciences’ Mowgli Holmes.

As his team has collected and analyzed samples from hundreds of cannabis plants and products, Holmes says one unexpected finding has emerged.

Marches for Science Linked to Earth Day

Apr 19, 2017

As science increasingly comes under fire from conservative political forces, public support for research and empirical evidence is being rallied in a global array of pro-science events this weekend—including two in Santa Rosa.

In thinking about the importance of science in daily life, Adrienne Alvord, the Western States Director for the Union of Concerned Scientists, points out that is it vital for both economic and personal health.

Project Drawdown's Climate Change Solutions

Apr 17, 2017

In agriculture, building, urban design transportation, energy production and use and more, there are steps already being taken to keep carbon out of the atmosphere. And according to a serious new book, scaling up those actions—all of them—could be a pathway to reversing global warming.

Many of the 100 climate change solutions examined by Project Drawdown have interlocking effects. Editor Paul Hawken says their analyses work scrupulously to keep their projected benefits separate.

Project Drawdown Aims to Reverse Global Warming

Apr 15, 2017

“Drawdown” is the term used to describe the time when greenhouse gases in the atmosphere have peaked and then begin to decline. A new book offers a pathway to get there by 2050.

The foremost consideration in the assessments made for the Drawdown Project, explains co-founder Paul Hawken, was how much carbon could be kept out of the atmosphere by wider adoption of each strategy.  In most cases, the 30-year impact could be measured in gigatons.

Changing How We Think About Aging

Apr 4, 2017

Don’t look now, but you’re already aging. So how are you going about it?  A science-based, musical show that is heading for Santa Rosa wants to change how we think about getting older.  Bruce Robinson has a preview.

Dr. Bill Thomas's  Changing Aging Tour will be at the Friedman Center in Santa Rosa on Thursday, April 6. It's a three-part event, and visitors can attend any or all of the segments. Thomas explains how they fit together.

Composting Toilets as an Aid to Sustainability

Mar 28, 2017

For decades, composting toilets have been an off-the-grid novelty. But in a time of limited fresh water and burgeoning interest in sustainable living, they are ripe for re-examination.

Sonoma County is hardly the only place that composting toilets have been put into use for remote rural residences. But Miriam Volat believes this area may be more receptive than most to the wider use of such fixtures.

Tracing Evolution's Limits

Jan 26, 2016

Evolution has been shaping life forms on planet earth for millions of years. Yet there are some entirely plausible—even probable—creatures that have never existing. Today we hear from a man who studies the question, “why not?” 

Gary Vermeij will be the featured speaker at the “Science Buzz Café” gathering in Sebastopol tonight. Find details about the event here.

The Geography of Genius

Jan 21, 2016

  Down through human history and around the globe, there have been occasional times and places where creativity and innovation flourished.  In The Geography of Genius, reporter Eric Weiner explores the conditions they share.

  Former NPR journalist Eric Weiner says he elected to apply a geographic approach to his survey of creative clusters, because he hoped it would offer insights that more conventional analyses have missed.

Exploring Sonoma County’s Varied Geology

Aug 9, 2015

From deep underground to right out in the open, Sonoma County’s geologic heritage is varied and fascinating. A special series of hikes next weekend offers close-up looks at some highlights, with explanations from a knowledgeable guide.

Another aspect of Sonoma County's recent geologic history--one that won't be featured in Melosh's transect hikes--is the mining that was active year in decades past. Evidence of that, especially for mercury, remains plentiful, but may be hazardous.

Inside Costa Rica’s Ban on In Vitro Fertilization

Jun 17, 2015
Azul Films

 

   Costa Rica’s vote to ban in vitro fertilization in 2000 was a political decision, but one with some painful personal impacts.  Both are traced in a bay area filmmaker’s new documentary, which comes to KRCB television Thursday night, just in time for Father's Day.

While Gabriella Quiros’ Beautiful Sin has been getting shown at festivals, and on some public television stations in this country, she is looking forward to taking it back to her homeland soon, where she expects it will generate a lot of attention.

Brain Health Registry

Dec 22, 2014

  A new online registry allows participants to monitor their own cognitive abilities, while also becoming part of a pool of people who might be part of future research projects studying human brain health.

Last week California Governor Jerry Brown signed a bill that requires the state develop an earthquake early warning system. Proponents of the system say it would save lives and avoid millions in damage during the next big quake. But as KRCB reports, no one yet knows how the system will be paid for.

Sleep and Memory

Aug 20, 2014

  Your brain relies on a good night’s sleep to properly code and store a day’s worth of memories. Lack of uninterrupted sleep can play havoc with that process—and is harmful in other ways as well. 

   Just as differing types of memories are linked to particular kinds of sleep, says Dr. Mehrdad Rezavi of the Marin Memory and Sleep Center, poor sleep will affect our overall well-being in the corresponding areas.

The Impactful History of Novato's Asteroid Fragments

Aug 19, 2014
CAMS

  The small meteor fragments that burned across the North Bay night sky 22 months ago apparently originated in the huge planetary collision in which our moon was formed, some four and a half billion years ago.

Because the falling meteorite happened to pass through the range where his cameras were focused and recording, SET's Dr. Peter Jenniskens was able to predict its path as it dispersed and came to Earth, and calculate it's far longer trajectory on the way into our atmosphere.

Bella, a 9-year-old dolphin at Six Flags Discovery Kingdom in Vallejo, gave birth last week to her first calf. The pair are surprising researchers and trainers as they communicate with each other. 

In her third trimester of pregnancy, Bella began emitting her "baby whistle" -- a unique call dolphins use to introduce themselves to each other. This behavior has never been observed before. Within minutes of being born, Bella's daughter also began to vocalize -- the earliest response recorded to date. 

Ozone layer on a long slow road to recovery

Dec 11, 2013
NASA Earth Observatory

Twenty five years ago the ozone hole above the arctic was the hot environmental topic. While we don't hear as much about it any more, researchers are still making new discoveries and say it's a topic that needs to remain in the public eye. KRCB's reports on the latest findings from a meeting of the American Geophysical Union now in San Francisco.

In a 1,000 year old village in Germany (Juehnde), methane is not a dirty word. The recovered methane from a manure-fueled bioreactor feeds the burners that heat water for every household in the village. The same hot water provides heating. These households benefit from living adjacent to a livestock economy whose manure was once just a smelly nuisance.

  As natural science and environmental education is increasing folded into lesson plans for students of all ages, the North Bay’s STRAW Project creates an annual learning opportunity for teachers.

You can find out more about the STRAW Project, and see a video about it's origins ( also featured on KRCB'S Natural Heroes) on their website.

Studying Roadkill

Aug 4, 2013

The vehicles on California’s ever-expanding network of roadways are getting faster and more numerous, which is bad news for the birds and animals nearby. So the number and location of roadkill deaths are now being recorded and analyzed.

  The online roadkill reporting site was launched with no assurance that there would be enough citizen participation to make it work, admits Fraser Shiller, co-director of the Road Ecology Center at UC Davis. But the gamble has paid off.

At times during the winter and early spring it looks like a vast inland sea between Sacramento and Davis. This is the Yolo Bypass, which shunts Sacramento River floodwater around the state capital during high flows. You drive over the bypass on a three-mile-long elevated stretch of Interstate 80 known as “the Causeway” (the Blecher-Freeman Memorial Causeway). The bypass is also the site of a lot of innovative fish and wildlife work.
