Henry Coe State Park won't be experiencing any part-time closures, but it will reduce trash and restroom service and has shuttered a new visitor center off the Pacheco Pass.

So you want to reserve that primo camping spot at your favorite California State Park? You might just have to take your chances. Most state parks are not accepting reservations through spring of 2010. It's part of a series of service cuts to slash millions from the State Parks' budget. Remember back in September when the Governor threatened to close 100 parks to balance the budget? Well, after a giant public outcry, he backed off but he still is requiring California State Parks to cut this year's budget by 14-million dollars. Superintendents from the state's 21 parks have come up with a plan to close that budget gap.

More than half of the state's parks will be scaling back days or hours. The list includes inland campgrounds and day use areas, many state beaches, museums and missions. In addition to reduced hours, trash and restroom service will be cut back at many state parks. I visited Henry Coe State Park in Morgan Hill. Because of it huge acreage (87,000 acres) and back country wilderness, Coe won't be experiencing any part-time closures, but it will reduce trash and restroom service and has shuttered a new visitor center off the Pacheco Pass. The park also lost all of its ranger aides. I also took a tour with the Superintendent at Angel Island State Park where they will be closing some restrooms, postponing school field trips and non-emergency repair needs. The situation is not expected to get better right away. The governor has already signed a budget that requires State Parks to cut 22-million dollars next year. California's parks have relied on the state's unpredictable general fund…and that has resulted in a billion dollar maintenance backlog. Park supporters are considering a ballot measure for next year that would impose about a 15-dollar a year vehicle license fee to pay for park operations. Want to hear more?

Am I Certifiable?

A technician checks the combustion efficiency and safety of a water heater—an important part of any home energy audit.

I hope I’m certifiable. I’ll find out in about a year when I’ve completed all the training and taken the written and field exams to become a Building Performance Institute (BPI) certified Building Analyst. The certification would allow me to perform energy audits on homes and maybe even get paid for it if I started an auditing business or joined an existing company. The certification would not prepare me to perform energy upgrade measures, such as air sealing and insulating an attic, only recommend the most cost effective ones. Many energy auditors work with a team of trusted contractors who can do the work the homeowner chooses.

My publisher Tom White and I decided that going through the kind of training that we have been pushing in our magazine will give me a more realistic view of the home performance industry, and the people who are just entering it now—the new weatherization workers, and newly minted technicians, contractors, and small business owners who will help build the new green economy. And it’s an excuse to get off my butt and out of the office more often. If I get certified, I’ll need to continue taking classes and have hands-on experience in the field to stay certified.

There are three kinds of certifications for a wannabe energy auditor to consider: certification as a Building Analyst through BPI; certification as a HERS (Home Energy Rating System) rater through the Residential Energy Services Network; or one of many “green builder” certifications that exist nationwide. I think the Building Analyst is the most basic. The training follows closely that of a HERS rater, but HERS raters need to become expert at rating software; it’s a bit more involved. I thought about being certified through Build It Green California as a Green Building Professional. But once I’m certified through BPI, I think it would be a small step to being certified by the other organizations.

Now I am asking what many people in the midst of career decisions are asking. Where do I go for the training and how much will it cost? BPI is in Malta, New York. (Might as well be Malta, the country.) Fortunately, BPI has hundreds of affiliates and approved trainers all over the country. There is also online training, and trainers who will travel to your hometown, as long as you have several people interested in the training. My plan so far is to complete an online training course through well-respected training organization, Saturn Online. That will prepare me for the Building Analyst written exam. I can even take the exam online. The course costs $595, plus about $70 for a book and field manual. Once you start the online course, you have about 8 weeks to complete it, so I can study and take the quizzes and final exam in my spare time—maybe over the holidays. The written exam fee is $225.

But you can’t get all the training you need online, nor would I want to. (Remember me wanting to get off my butt more often?) Saturn also offers three day intensive hands-on field seminars in locations in several locations around the country that culminate in the Building Analyst field exam. I have friends in Portland I haven’t seen in a while; maybe I’ll go there for my field training. The field seminar costs $950. If you want to take the exam at the end of the seminar, there is an additional $350 charge for proctoring. Total costs of going for BPI Building Analyst certification: $2,190. The value of certification: priceless.

Science Event Pick: Wonderfest '09

The Bay Area Festival of Science
The first weekend of November is science geek nirvana with the return of a Bay Area gem: Wonderfest, the Bay Area Festival of Science. The 2-day festival is Saturday, November 7th (on Stanford’s campus) and Sunday, November 8th (on Berkeley’s campus).

Every year, Wonderfest pairs researchers to answer provocative questions in the world of science. The point is to create an engaging dialogue between the scientists and the audience, empowering people to make up their own mind.

I’m always blown away by the scientific luminaries that take part in the dialogues. Just last year, there was a dialogue on our energy future featuring current Secretary of Energy (and Nobel Laureate) Steven Chu and co-lead author of the IPCC report on climate change Dan Kammen.

This year is no exception with an expanded line-up of exceptional dialogues:

Does Moore’s Law Apply to Energy Technology?
Does Media Violence Inspire Real Violence?
Is Evolution Still Darwinian?
Do Robots Make Better Astronauts?
Does Darwin Illuminate Emotion & Spirituality?
Can We Create Life?

Dialogues not your thing? This year brings the debut of the Amateur Science Forum, (exhibitions of local citizen science programs), the Bay Area Science Expo (shop for science inspired books, crafts, and music), and my personal favorite: the Mind Duel. The Mind Duel is a science quiz competition between a local high champion and a panel of local science professors. A Nobel Laureate humbled by a local high student…it’s possible and likely at Wonderfest.

Wonderfest 2009

When: Saturday 11/7 1-10 PM, Sunday 11/8 10 AM -5 PM
Where: Saturday – Hewlett Teaching Center, Stanford University
Sunday – Stanley Hall, UC Berkeley
Cost: FREE
Details: Through public discourse about provocative scientific questions, Wonderfest aspires to stimulate curiosity, promote careful reasoning, challenge unexamined beliefs, and encourage life-long learning. Wonderfest achieves these ends by presenting series of scientific events to the general public. At most of these events, pairs of articulate and accomplished researchers discuss and debate compelling questions at the edge of scientific understanding.

Living in Limbo: the Zombie-like Qualities of Prions

Prion diseases are neurodegenerative, attacking the brain. Could they be responsible for the recent wave of Zombie attacks across the globe? Original photo: digitalsextant. I’m a sucker for zombie movies; I’ve watched dozens of them. I am especially fond of the Resident Evil Trilogy, where the T-Viruses effectively restructure mortality and create a world of zombies. There is something incredibly satisfying with the zombie movie plot – a virus outbreak devastates a planet but a group of people are immune and fight to save humankind. Having the ultimate evil as a virus also makes it seem more plausible and compelling. Yet viruses and bacteria do not live in limbo. They are alive and under the right conditions can be killed. Which is bad news for Zombies.

But what if there existed a substance that acted like a virus or bacteria but wasn’t living? Medicine made a revolutionary leap during the time of Louis Pasteur in the mid 1800's. The inventor of food pasteurization and one of the founding fathers of microbiology – he was able to prove germ theory. Food spoiled and organisms got sick because of the growth of bacteria and viruses within them. Within sterile environments, viruses and bacteria could be killed off and food could be preserved or organisms could recover from illness or infection. Sterilization works on living micro-organisms. Prions, however, are not living organisms.

Prions are infectious proteins. For unknown reasons, these proteins refold abnormally and cause a domino effect in surrounding proteins which in turn mutate into stable structures. Prions will then cause tissue damage and cell death to surrounding areas. Prion diseases are neurodegenerative, attacking the brain and are characterized by "holes" in the tissue. The incubation time for Prion diseases is quite long. They usually surface later in life but after they surface, the diseases are rapid and fatal. Such examples of Prion diseases include Mad Cow Disease in cattle, Scrapie in sheep and Fatal Familial Insomnia in humans. FFI is a disease that literally takes away the ability to sleep and in a few months leads to death. The Book “The Family That Couldn’t Sleep” by journalist D.T. Max follows a family in Italy that passes this disease from one generation to the next over subsequent centuries.

Prions have been and still are a medical mystery. What causes them to mutate and aggressively eat away at the brain? How can they be stopped? Because they are not living they are highly resistant to sterilization methods. While viruses and bacteria can be eradicated on equipment through heat, radiation or chemical reagents, Prions are strongly immune. Maybe Zombies are not so far off after all – lurking in the shadow of medicine has been a mutation that is resistant, brain-eating and neither alive or dead. It has some serious similarities to the zombies I have watched over and over again on the big screen.

If you want to learn more about Prions and their history, check out Down to a Science’s next reading group which is focusing on the book The Family that Couldn’t Sleep or check out the book Deadly Feasts: The "Prion" Controversy and the Public's Health by Richard Rhodes. And one more thing – Happy Halloween!

An Incomplete for 23andMe's Carrier Testing

What can genetic testing tell you?

A while back I took a 23andMe genetic test that looks at over 600,000 different spots on my DNA. The last few blogs I have been going over my genetic test results with an eye on how useful they are. And how well the results are explained.

Last blog I wrote about how current genetic tests aren’t that great at predicting your risk for common, complicated diseases like diabetes or Alzheimer’s. This time I thought I’d focus on what today’s genetic tests can be very good at and whether or not 23andMe does a good job with these.

Current genetic tests are very good at predicting your risk for rare, simple genetic diseases like cystic fibrosis (CF) or Huntington’s disease (HD). And at predicting the chances that your kids will get these diseases too.

Genetic tests for these diseases work because most of them are caused by a single gene gone awry. Testing for a single gene is relatively easy.

For example, most cases of CF happen because of known differences in the CFTR gene. A genetic test can look for these differences and tell you if you and/or your spouse have any of them. If you both do, they can also give you a pretty good idea about the chances that your kids will get them too.

Of course, we don’t know all of the differences in the CFTR gene that can cause CF. And some differences only cause CF some of the time. And there are people with everyday, run-of-the-mill CFTR genes who get CF because of differences in different genes.

Still, as genetic tests go, these are pretty good. If a test comes up with a known CFTR difference that causes CF, then you have a pretty good idea of what your chances for developing CF are. If your spouse gets tested too, then your kids’ chances can be determined as well.

So how does 23andMe do? OK, I guess…

First off, they look at eight of these sorts of diseases under a category called Carrier Status. The diseases they look at are shown in this image:

CarrierStatus

For me, the first big result is that I am a carrier for a variant that can lead to hemochromatosis. This isn’t surprising since 1 in 8-12 people of Northern European descent in the U.S. are too, but it is definitely something to watch out for. It may be important for my wife to be checked too so we can make sure none of our kids got two copies. (Luckily hemochromatosis is easily treated by giving blood on a regular basis.)

Some of the other results are less illuminating. For example, I do not carry the CF difference they test for (delta F508). This is of course great news. Unfortunately, this variant only accounts for about half of the CF cases out there. Which means I could be a carrier for CF, just not a carrier of the most common variant that they happen to test for.

The same thing goes for most if not all of the other carrier status diseases (sickle cell anemia is an exception). Some like BRCA (breast cancer) are as poorly covered as CF while others like Bloom’s disease cover a larger percentage of cases.

23andMe is pretty upfront about the limitations of their testing once you dig a bit into the results. But still, if they’re going to look at 600,000 different parts of my DNA, you’d think they could add a few more to give me a stronger answer about whether or not I am a CF carrier.

Reporter's Notes: Catching the Drift – Part 2

Luis Medellin and Karl Tupper set up a drift catcher in Lindsay, CA.

My radio story on pesticide drift looks at how residents in the citrus town of Lindsay are monitoring pesticides in the air and in their bodies. They are using a device called a Drift Catcher, modeled after technology used by the California Air Resources Board and the Department of Pesticide Regulation.

The pesticide drift catcher has a vacuum pump that sucks air into a glass test tube, where pesticide residues are trapped in a resin. Community members change out the test tubes and send them to a lab, where scientists crack them open, extract the residues with an organic solvent, and then analyze those extracts through gas chromatography.

The Lindsay study measures Chlorpyrifos, a pesticide that can cause headaches, blurred vision, and muscle weakness when people breathe in the air from a recently-sprayed orchard or field. Studies also show prenatal exposure MAY have effects on children's cognitive and motor skills.

Environmental lawyers are using preliminary data from the Lindsay drift catchers in a petition asking the EPA to create pesticide buffer zones around schools, child care centers, and hospitals.

Web of Stars

Students in Cork, Ireland interacting live via Skype with Chabot
during real-time observing session.
What do Chabot's 36-inch telescope, Nellie, and a classroom full of 14-year-old girls in Cork, Ireland have in common? In a few words, the International Year of Astronomy and the Web of Stars!

Wednesday morning around 1:00 AM, Chabot staff astronomer Conrad Jung and I fired up the systems in the 36-inch observatory and made a Skype video call to the Blackrock Castle Observatory in Cork, Ireland. Staffers Frances McCarthy and Alan Giltinan answered—it was 9:00 AM for them, and Frances had already been up four hours to prepare for our premiere session of Web of Stars. A bus-load of girls from a local school were on their way through the downpours of rain Cork was experiencing at the time.

On our end, everything technological was working fine: Nellie, our 36-inch telescope, was stoked, motors humming and ready to drive us to faraway celestial locales; computers were singing (in their own particular way), and the webcam-Skype interlink was green. The webcam view nicely framed the telescope, making a great background for the session.

A little after 2:00 AM PDT, the girls from North Presentation Secondary School rolled into the classroom, and there was a great deal of excitement. Eight or nine of them immediately descended upon the microphone and webcam and started chirping "helloes" and "hi's" at us across the 5,000 mile gulf (what's an ocean and a continent to get in the way of the Internet?).

After the greeting buzz died down, and the girls' teacher and the facilitators at Blackrock Castle got them to their computer stations, the morning's work began….

"We regret," Conrad and I had to inform them, "that the weather at Chabot is damp, and we're completely fogged out." This was a disappointment, of course, but we had a Plan B lined up in the event of bad astronomy weather. From Conrad's archive of astrophotography, we pulled up some un-processed astronomical images from months past and dumped them to our FTP server, where Alan at Blackrock Castle immediately downloaded them to the girls' computers: Comet Lulin, the Andromeda Galaxy (M-31), the Hercules globular cluster (M-13), the Apollo 15 landing region on the Moon, the Great Nebula in Orion (M-42), and the Ring Nebula (M-57) were the fare for the session.

With the astro-image processing software Salsa-J, the Cork girls proceeded to process the images—taking each set of three color channel (red, green, blue) black and white images and combining them into composite full-color images. Throughout the 2-hour session, the girls broke away from their computers two and three at a time to come to the microphone and chat with Conrad and I—we were even treated to a song or two from the girls, one by the entire class: On the Banks of My Own Lovely Lee.

The Web of Stars program was conceived of by Blackrock Castle Observatory, and Chabot became the partner observatory through proximity to San Francisco, which is a sister city of Cork. In Ireland, classrooms competed over the summer to earn one of the six pilot observing sessions with Chabot, and the program will unfold from October through March with one session each month.

Though we had to resort to our bad weather Plan B ("B" for "bad" weather) for our kick-off session, the A plan ("A" as in "actual active astronomy") will be for us to acquire and image objects with Nellie from lists of targets sent to us by the students in Cork, and deliver them in real time to the classroom at the Castle, where they will conduct the image processing and measurement activities in lock step.

Please wish us and the students in Cork good weather!

Science Event Pick: BOSS of the Night Sky

The Sloan Telescope used to conduct BOSS
A long time ago in a galaxy far far away…Well, to be precise, 14 billion years ago and at the beginning of the universe was the Big Bang. Ever since that moment, our universe has been expanding, but over the last 7 billion years that expansion has been accelerating. Why? Scientists don’t really know, so they came up with an ominous term as a placeholder: Dark Energy (Another possible explanation is that that our theory of gravity is wrong, but we’ll skip that for now). Recent calculations project dark energy makes up nearly 70% of the mass-energy of the universe. 70% of the universe is a mystery? That’s the kind of puzzle that inspires scientists to craft unique experiments.

One of those is BOSS, the Baryon Oscillation Spectroscopic Survey, is a new project to create a 3-D map of over 2 million galaxies and quasars representing the best data ever obtained on the large-scale structure of the universe. Baryon oscillations began as pressure waves through the hot plasma of the early universe. Those waves left an imprint on the matter that makes up the universe, including the dark matter. The survey will essentially act as a ruler, in order to measure how the universe has been expanding.

Next Monday, you’ll be able to meet David Schlegel, the principal investigator of BOSS. He’ll be part of a panel of Lawrence Berkeley Laboratory scientists discussing their search for dark energy. As a primer, check out QUEST’s story on Dark Energy from last year. The piece features astrophysicist Saul Perlmutter, who will also be speaking at the event.

Wildlife + Creative Thinking = Hope: A Day at the Wildlife Conservation Expo

This year's Wildlife Conservation Network Expo in full swing at the Mission Bay Conference Center.

It’s a sunny, fall day in October and I am driving into San Francisco. I pass the colorful Love Parade floats revving up without a glance of longing. I pass the turn towards Golden Gate Park for Hardly Strictly Blue Grass Festival without an ounce of FOMO (fear of missing out). I giddily park outside of Mission Bay Conference Center and enter the Wildlife Conservation Network’s yearly Expo. Parades and music will have to wait; I am ready to gorge myself on colorful wildlife and rock star conservationists. Each year I am more amazed and enthralled by this extraordinary event.

The Wildlife Conservation Network (WCN) was founded in 2002 in Los Altos by Charlie Knowles and Akiko Yamazaki. Their unique approach to conservation is based on the venture-capitol model and offers organizations expert networks, fundraising support, global exposure and Silicon Valley expertise. 100% of donations to WCN go to programs. It is an efficient system with measurable results and an excellent example of conservation action.

The Wildlife Conservation Expo is a dream come true for wildlife people, and after many years of attending, it feels like an international family reunion of cousins related by their passion for animals and the natural world. Flying in from 30 countries, including the mountains of Uganda, the savannahs of Zimbabwe or the steppes of Uzbekistan, they come together to share their miraculous projects. I marvel that I simply need to navigate the s-curved bridge from Oakland to be amongst this kin of conservation heroes.

The day consists of short and sweet speaking sessions from these 24 wildlife powerhouses, each one more inspiring than the next. Between sessions, participants visit the many tables featuring local, national and international groups and projects. The Oakland Zoo table was surrounded by such favorite groups as Africa Matters, Animals Asia, WildAid, Reptile & Amphibian Ecology International, Project Tamarin, Mountain Gorilla One Health Program, Red Panda Network, Elephant Voices, or our Teen Wild Guide’s favorite, The Saiga Conservation Alliance. Add in mingling with hundreds of like-minded people, and it is a day that can’t be beat. Oh, did I mention Jane Goodall is the keynote speaker? As I write this, I watch her graciously speak with participants, sign books and scratch the head of one of the Working Dogs for Conservation. Lucky dog.

At Dr. Jane’s presentation, she begins with her uncanny chimp-like pant-hoot greeting and reminds us that passion is the most powerful asset one could have. That if we all explored and exercised our passions, what a different world it would be. As usual, I leave WCN with new ideas, new reasons to be hopeful and renewed gratitude for WCN.

The 2010 dates have yet to be decided. Watch the website for details.

The Large Hadron Collider Gets Ready to Spin Again

 

Christopher Smallwood by Christopher Smallwood  October 19th, 2009

The Large Hadron Collider, if located in the Bay Area, would encompass a sizable piece of San Francisco. Image Credit: NASA.In about one month the world’s biggest science experiment, the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, will once again fire up. So now may be a good time to stop and remember what a stunning and ambitious project this is. Indeed, it becomes hard not to get lost in such an endless list of superlatives once you start noticing. I have gleaned a few below. See CERN’s website for more, or Jennifer Skene’s blog for a great set of LHC links.

She’s Electric: To power a standard light bulb you need 60 Watts (or 15 watts for an equivalent CFL). To power a small house you need an average of about a thousand watts. To run the LHC at full power researchers will need 120 million watts. Alternatively, you could run the LHC, supply electricity to a population the size of Berkeley, or simultaneously bake 60,000 Thanksgiving turkeys. You could only fly three 747 airplanes, though.

Life in the Fast Lane: A fundamental axiom of physics states that no information can travel faster than the speed of light. The LHC’s proton beams are no exception, but their speeds do approach light speed to within a fraction of a millionth of 1 percent. Such velocities defy comprehension. Suffice it to say that if we ever managed to accelerate a person to this velocity, time would warp so much that we could expect her to live for half a million years.

The Long and Winding Road: The LHC’s 17-mile circumference could make it a nice racetrack for a half-marathon, but don’t try racing the beam. When operational, protons will shoot around the LHC more than 11,000 times per second. Even more mind-boggling is the length of wire used in the construction of the LHC’s thousands of superconducting magnets. CERN claims there is enough wire wrapped up in these magnets to trace out more than six trips to the Sun and back.

OK Computer: When operational, the LHC is expected to generate 15 petabytes of data and simulations per year, which amounts to the hard drive space of about 30,000 high-end personal computers. At CERN in 1989, Tim Berners-Lee and Robert Cailliau revolutionized the world with their development of key pieces in the framework of the World Wide Web. The networks being developed to manage the LHC’s expected data have inspired talk of a similar revolution to come.

A Whole New World?: All of these wonders of physics and engineering have been developed for the purpose of one thing: to create a particle smasher with the capability of knocking two protons together with an energy of 14 TeV (trillions of electron volts). This is about the same energy that it takes to pick a grain of salt up off the floor. Compressed into such an acute space, however, it just might lend us insight into the most fundamental properties of our universe.

Now, if they can only get those wires hooked up correctly…
