    Producer's Notes – Why I do Science: Healy Hamilton

    July 7th, 2009 by Joan Johnson

    Aquaman was Healy Hamilton's favorite superhero growing up.

    When I first heard about Healy Hamilton at a meeting QUEST was having with the California Academy of Sciences, I just knew I was going to like her. I mean, what kind of scientist studies not only the effects of climate change on biodiversity, but also has independent projects with river dolphins, seahorses and octopuses? Talk about Bio…Diversity! (ouch)

    So what do you do with a scientist with such diverse interests? Well, we featured her in no less than three QUEST TV stories in our third season. (Incidentally, this record is only matched by another Cal Academy Scientist, Bob Full. I guess they attract a lot of very interesting people over there at the Academy).

    This latest story "Why I Do Science" is geared towards kids (and Aquaman fanatics). Also see Healy in ""Seahorse Sleuth" and "Climate Watch: California at the Tipping Point."

    Producer's Notes: Seahorse Sleuths

    May 19th, 2009 by Joan Johnson

    babySeahorses are sold as expensive ingredients used in
    traditional Chinese medicine.

    When I was a kid I rode horses and was an avid ocean swimmer, and I absolutely fell in love with all sea creatures. But there was a special place in my heart for the one that seemingly combined my land and sea passions, the seahorse. Come to think of it, I don't think I actually thought these undersea chimeras existed in real life…in my mind they lived in storybook land along with unicorns and Mr. Tumnus. I mean, I never saw a real one…so how could I know? But these days kids are getting familiar with the real deal thanks to the hard work of a handful of public aquariums, like the Monterey Bay Aquarium, The Steinhart Aquarium, The National Aquarium in Baltimore, The Shedd Aquarium, and The Birch Aquarium among others.

    Not surprisingly, I jumped at the chance to produce the Quest "Seahorse Sleuth" story, but I will admit that the process of making this piece was demoralizing, to say the least. I spent days in San Francisco’s Chinatown trying to get shop owners who sell Traditional Chinese Medicine (TCM) to talk to me about their trade, and specifically about seahorses. I must have visited 20 or so stores, multiple times, and I saw many hundreds of dried seahorses and thousands of shark fins, not to mention enormous piles of antlers, skins, penises, and whole dried animals. Though I tried many different approaches, no one would talk to me…I was clearly an outsider and not to be trusted. (Had I managed to garner the trust of one of the shop owners, I would have certainly included them in the piece). This experience made me even more impressed and appreciative of the hard work that the folks at Project Seahorse are doing, and exhausted at the thought of how far they still have to go to convince fisherman and governments around the world not to decimate their seahorse populations.

    But whereas Project Seahorse must be measured and careful in their approach to these conversations about TCM in order to make headway, I feel that in this blog I can be more forthcoming about my feelings about the use of these animals, and all animals, in TCM.

    Of course TCM has a rich history dating back at least 2,000 years, and at least a quarter of the world's population uses this form of medicine. I myself find acupuncture and herbal remedies to be very helpful and do not wish to debunk the efficacy of at least those two parts of the tradition. But I personally draw the line at the use of animals, because I'm a huge animal lover, and I am absolutely appalled at the use of endangered or threatened species for any use. This planet may have seemed endlessly bountiful 2000 years ago, but today we can no longer afford to take the survival of non-human species for granted. To add salt to the wound, it is my understanding that China does not, as of yet, perform the kind of rigorous testing of these products that we must perform for drugs in the U.S. to determine their effectiveness. (This is why we get products from China with arsenic in them, for example). One of the main uses of dried seahorses (and many other dried animals) in TCM is for male virility, though I do not believe there have been any studies that actually prove it has any effect on virility. I don’t know about you, but I think it’s dumbfounding that a country with an official one-child policy, which has led to female infanticide levels that have caused a significant gender imbalance in China, thinks they need to ingest threatened and endangered species to improve the potency of their male population. Let's put the pieces together here folks.

    Ok, I'm going to get off my soapbox now, since I'm getting into territory that I am certainly not an expert in. But I did want to present this topic for open discussion – since that's what blogs are for. But before you get too riled up, let me suggest a few websites for further research.

    First of all, learn what you can do to help save seahorses by signing on to the Monterey Bay Aquarium's Seahorse Conservation Page. You can also brush up on the specific uses of Endangered Animals in Traditional Chinese Medicine with this informative paper on Encyclopedia's “Advocacy for Animals” site.

    TRAFFIC (The Wildlife Trade Monitoring Network) has a new Chinese-language textbook aimed at raising awareness on how to best protect threatened species used in TCM. Lastly, check out The World Wildlife Fund’s FAQ page on Traditional Chinese Medicine.

    And that’s just to get you started…the web has plenty of information on this topic…read it and tell your friends!

    Producer's Notes for Cool Critters: Opossums

    March 31st, 2009 by Joan Johnson

    "Opossums are marsupials, just like kangaroos."I think opossums get a bum rap. People think just because they look kind of funny, walk kind of funny, have beady eyes and sharp teeth, and can emit the most foul-smelling scent you've ever had the misfortune of coming across, that they are kind of "icky."

    But they are just trying to make a living like everybody else. They need those teeth to crush bone – which means that they are good for clearing out those unwanted rodents in your neighborhood. (No, they are not rodents themselves; opossums are marsupials… that’s right, just like kangaroos!). Their eyes… well, they just look that way and they're not particularly useful, however these critters have an excellent sense of smell and hearing to make up for it. As for that smell that they emit, they only do that when they're fighting for their lives. Believe me, if you could spew a foul stench when some unsavory character is harassing you, you'd do it! And let me take this moment to clear up a very common misconception: no, opossums cannot hang by their tails, though they can use them to balance themselves and gather bedding materials for their nests.

    The truth is, if you ever get the chance to know one like we did, you'll see they are really sweet creatures. Most of the times that they find themselves in direct conflict with humans, it’s the human's fault. Their habitats are shrinking due to our development plans, which forces them to live closer and closer to us. If you leave your pet food outside… well, who doesn't take a free snack when it's offered up? And the poor creatures only live for two to four years, so please folks, give the opossums a break!

    Producer's Notes: Zeppelins Resurrected (Bonus)

    March 17th, 2009 by Joan Johnson

    The Airship Ventures airship "Eureka" takes off from Moffet field.

    Let's face it… being assigned to fly around the San Francisco skies in a brand new, sleek-looking zeppelin for "work purposes" just further confirmed my excellent career choice. (Plus, I just got lucky). It's so amazing to see our world from that vantage point: intertwining freeways that look like pulsating blood vessels; miniature toy cars on miniature toy bridges; the two-mile long Stanford Linear Accelerator fitting into just one frame on my camera.

    It's easy to see how these new, nearly silent zeppelins could be used in a myriad of ways – from spying on whales to aerial photography to weather and climate monitoring. But there's also nothing wrong with just celebrating the romance of airships, and having a darned good time doing it. It's certainly an experience I'll never forget, and I'd recommend a flight in the Eureka to anyone!

    Producer's Notes for Bio-inspiration: Nature as Muse

    October 21st, 2008 by Joan Johnson

    I was a biologist once, before I got into television, so I find these times particularly trying when I see schoolteachers and otherwise intelligent people calling evolution into question. That's part of the reason that I jumped at the chance to co-produce a story about bio-inspiration (the other reason being that I LOVE geckos…which will make more sense if you watch our QUEST Bio-inspiration segment).

    Bio-inspired design borrows its creative inspiration from models and systems in nature, that is, plant and animal parts that have been slowly tweaked for over 3.8 billion years. But that doesn't mean that nature's designs are perfect. In fact, that's what makes the process of engineering things based on natural models so difficult. You have to figure out how to pull the aces from the evolutionary discard pile. As professor Bob Full at U.C. Berkeley explained in our first phone conversation, that's also why scientists now use the term "bio-inspiration" rather than the more commonly known term "biomimicry." Biologists and engineers are not looking to simply mimic nature, because there are all kinds of dead ends and redundancies in natural systems that would be pointless to recreate in an optimized, man-made piece of technology. One of the examples he gave me is a kind of grasshopper that if you were to copy it, you would copy neurons that go to nothing, they don't connect to any muscles, and that's because during evolution the adults lost their ability to fly. The neurons going to the muscles are still there, but the muscles aren't there anymore. No need to copy that, right?

    So what a biomimeticist does is look to nature to find plants & animals with remarkable performance abilities, and studies their adaptations for inspiration to design something new. For example, if you want to make a tiny robot that can fly, then look at the best fliers. If you want to design a blade that moves quickly through fluids, or an Olympic swimsuit that minimizes drag, then look to the most efficient swimmers. Now that's what I call "intelligent design!"

    Producer's Notes for Cool Critters: Fruit Bats

    October 14th, 2008 by Joan Johnson

    In honor of Halloween this month, Quest offers up a short story on bats. But these are not your screeching, swarming, bloodsucking Hollywood movie bats. No… just like you can choose to make a cute, happy jack-o-lantern or a scary jack-o-lantern, you can also choose to do a story about cute fruit-eating bats instead of their less attractive cousins.

    So we visited zookeeper Andrea Dougall at the Oakland Zoo to learn about their Malayan and Island Flying Fox. Both are a type of fruit bat, and I couldn’t readily see the difference between them. There are many fascinating things that Andrea taught us about these bats that we couldn't fit into our two minute segment (and honestly, this producer wouldn't mind making a half hour special on these critters!). For instance, they have a lot of blood vessels in their wing tissue, so they make excellent thermo-regulators. If the bat is cold, he wraps himself up in his wings so that the heat from his blood vessels can keep him warm. Likewise, when it's hot out the bats flap their wings to cool off.

    When Andrea told us that bats are the only mammals that can have sustained flight by flapping their wings, someone said "but what about the flying squirrel?" Nope– they glide.

    These bats don't actually swallow the fruit that they eat, instead they chew it into small pieces, push it up against the roof of their mouth to ring out the juice, which they then swallow, and spit out the leftovers. This is something that Andrea reminded me of when I told her I'd like to take one of these cute critters home as a pet… the amount of rotten fruit pulp that you have to pick up is really unappealing. Plus, of course, it would be illegal.

    Perhaps the most intriguing thing to me is the simple fact that these animals spend all of their time hanging upside down. I asked Andrea about that too– how is it possible that they wouldn't experience some sort of leg fatigue and let go of their grip? She told me what's in the scientific literature on other kinds of bats (and we're assuming it applies to fruit bats as well). The deal is that the tendon of the muscle that flexes the claw passes through a tough sheath that consists of 19-50 rings, oriented at an angle so that the inside surface is ridged. So there's some ratchet-action going on in the sheath that holds the claw in a grasping position even after the muscle has relaxed, and it's the tension on that tendon from the body weight that holds the ratchet in place. When the bat wants to move, the tension is released and therefore the claw releases its hold. So basically, the clenched position is the "at rest" position, and the releasing of the foot is the part that takes energy.

    If you haven't yet, I highly suggest you make a trip over to the Oakland Zoo to see these highly captivating animals for yourself.

    Producer's Notes: Physics of sailing

    September 30th, 2008 by Joan Johnson

    Editor's Note: Guest blogging for Producer Joan Johnson is QUEST team member and sailing fanatic Sandy Schonning.

    The real physics of sailing are so deep and so complex, people
    are still debating it.

    It was another average Tuesday. I was sitting at my desk, looking at my calendar. Another day of budget meetings, returning emails, reviewing contracts, yawn. The usual buzz of production was going on around me, a crew going out to do a story about… sailing. Ah sailing, my favorite topic. My husband and I had recently moved both ourselves and our Tayana 37 up the coast from Long Beach. Okay, a well-qualified captain had actually moved the boat to San Francisco for us… but since Polaris had gotten here, we had become a bit obsessed about Bay sailing. Sailing in So Cal had not prepared us for the currents, tides and winds of the Bay, so we tried to get out there as much as possible.

    Okay, back to Tuesday morning. The buzz moved over to my desk… the shoot was supposed to show a group of beginners on a sailing lesson, but the family that was booked for this purpose had suddenly cancelled that morning. Could I fill in? I considered my clothes… skirt, heels, not really sailing clothes. And moving all those meetings… but a day on the Bay… the beautiful, sunny, windy Bay. Plus, sailing with an instructor, there is always something to learn about sailing, how could I pass this up? Okay when are we leaving? No wait, what am I going to wear… isn't there a West Marine near the sailing school. Can we stop to get me pants and a pair of shoes? Yes, that's how much I really wanted to go out that day, I bought new clothes to do it.

    It was a great day on the Bay. Stan, our instructor from the sailing school, was great at explaining the physics behind why a boat sails. At the direction of the producers, I asked every sailing question I could think of. Who has the right-of-way, what is this line for, what do we do when the wind blows harder? Okay, I knew many of the answers, but I babbled on anyway. Was I having fun? In much of the segment, I have the goofiest grin on my face. I wish I had a job that took me sailing every day…

    Anyway, it was over too quickly – and then it was back to my meetings. But I'll tell you the biggest surprise of the whole experience: I though the physics behind sailing were pretty simple – a little Bernoulli Principle, a little lift generation. But what I learned made my head spin. It turns out that most of the simple explanations of sailing physics are ‘helpful models' that make sailing understandable to sailors. The real physics of sailing are so deep and so complex, people are still debating it. If you'd like to see what I mean, check out Arvel Gentry's website. Gentry was an aerodynamicist for 40 years, is an avid sailor, and an America's Cup boat designer. His technical papers will give you an idea of what's really going on:

    Producer's Notes: Cool Critters: Owls

    May 12th, 2008 by Joan Johnson

    The day was hot, the owl was angry… we shot this really fast. It's not Olivia the owl's fault, it was just one of those days. As we all know, owls are nocturnal creatures, and we happened to be filming Olivia during the hottest, brightest part of the day. If your eyes were that big and we made you perform for us on camera at high noon, you'd be squinting and hissing at us too!

    But the greatest disappointment, in the end, was that I did not have enough time in this segment to tell our audience about all of the amazing adaptations that this creature has. Their claws are enormous and powerful, they have excellent hearing, and fantastic vision in low light. But perhaps one of the coolest things about the Great Horned Owl is that they can fly almost silently due to "fringes" on their feathers that help to break up the sound of air passing over their wings.

    The other thing people might not know is that the famous "hoo-hoo-hoo" sound that we make when we are imitating owls comes from the Great Horned Owl. People tend to think all owls sound like this because the male GH owl's call is often used in Hollywood movies, no matter what kind of owl is being depicted on screen.

    Olivia and her ilk are well adapted, formidable hunters, and truly gorgeous to look at… go and see for yourself at the Oakland Zoo.

    Producer's Notes – SETI: The New Search for ET

    April 1st, 2008 by Joan Johnson

    The Allen Telescope Array.When I first began to work on Quest's SETI: The Search for ET segment, I have to admit that my initial reaction was "are we still looking for ET?" Of course, humans have been gazing up to the heavens for millennia, asking ourselves that interminable question "are we alone?" And of course, there's been a long line of increasingly sophisticated radio telescopes searching the skies for cosmic signs of intelligence. But hey, don't we at some point have to call it a day? Though I think most of us don't actually believe we're alone, the universe is really, really big. What chance do we have of finding ET?

    Well, it turns out our chances are much better than I thought. Grote Reber began conducting sky surveys in the radio frequencies with his newly invented radio telescope in 1937, and detected the first signals from outer space in 1938. In the seven decades since then, we've seen a multitude of radio telescope designs pop up all over the world, but we still haven't gotten signals from any little green men. What I didn't understand, until I spoke to Jill Tarter and Seth Shostak at the SETI Institute, is that in all that time, we've hardly looked at any space at all.

    Since SETI's first experiment in 1960 by Dr. Frank Drake, and until very recently, they've only looked at a thousand stars out of about 400 billion stars in our galaxy, and there are 100 billion other galaxies to look at! There are two reasons for this: 1) The radio telescopes they've been using can only look at narrow swaths of the sky, and 2) they've had to RENT time on other people's telescopes, which constrains their search and budget. Now, the new Allen Telescope Array is being built just for them, and with it they'll be able to capture millions of frequencies from multiple star systems simultaneously. It will be the biggest and fastest tool in the world for seeking signs of ET!

    To learn why scientists use radio frequencies in the hunt for intelligent life, and to learn more about the history & future of the search, watch our story SETI: The Search for ET. You can also watch our extended interview with Astronomer Jill Tarter. And hey folks, the SETI Institute is a non-profit organization, so if you'd like to help them out with the search, consider adopting a scientist like Jill Tarter or Seth Shostak. Go to Adopt-a-Scientist, or join Jill's team and become a TeamSETI member at Join TeamSETI.
    Also, check out U.C. Berkeley’s SETI@home page and turn your home computer into a tool that downloads and analyzes radio telescope data.
