Cal Academy and The 11th Hour Project are bringing some excellent speakers to town."Yeah, it's a lot of fun to have a drink and look at the octopus." – Anonymous Friend talking about Cal Academy's Nightlife

Maybe this is a reflection on my choice in friends, but the above quote is a common comment about the Academy's wildly successful adults only Nightlife program (just check Yelp). Yet if you go a touch deeper than the rockin' DJ, numerous bars, and diverse exhibits, there is a wealth of interactive programs to exercise your brain. This month may bring the most celebrated speakers yet, all thanks to the folks at the 11^th Hour Project, a non-profit dedicated to creating a sustainable world.

Opening the month are Dan Kammen & Sally Benson discussing the emerging green energy economy, focusing on the novel technological solutions to the global energy issues. In case you were worried about their credentials, Dan is the lead author for the UN IPCC panel (they netted a Nobel Prize in 2007) and Sally is one of the pre-eminent U.S. experts on carbon sequestration.

On 9/10, Annie Leonard takes the stage to discuss her popular polemic, The Story of Stuff. Annie's tale is 20 minute tale of our unsustainable production and consumption pattern. The viral video is now well past 7 million views, all from a filmmaker who was curious what happens to all our "stuff".

Maya Lin, the Chinese-American artist who designed the Vietnam Veterans Memorial, unveils her new sculpture titled "What is Missing?" in the East Garden on 9/17. She'll discuss the new piece, which is dedicated to raising awareness of biodiversity and habitat loss, as well as her artistic process.

Finally, 9/24 is the night for the disappearing glaciers. Orvile Schell, the director of the Center on US-China Relations, has been documenting the decline through photography. Beyond his stunning photos, Orville will discuss his work to create a cooperative strategy between the US and China (the top 2 greenhouse gas emitters) to reduce their carbon emissions. Filmmaker and mountaineer David Breashears will also discuss the glacier disappearance through his 1^st hand accounts of traveling to receding sites on the highest peaks of the world. He knows a thing or two about high peaks; David was the first American to summit Mt. Everest twice.

Often at the California Academy of Sciences, you will see docents out on the floor of the museum with an example from our live animal collection.The Academy offers chances to get up and personal with a variety of reptiles, including Skinks and Ball Pythons. Docents follow up these close encounters by offering antimicrobial soap to guests to clean their hands– not because the animals are slimy or grimy, but as a precaution against transmitting Salmonella bacteria from animals to people.

You've probably heard of this bacteria before, as an unpleasant bug that sometimes finds its way into high-protein foods such as meat, fish, and eggs. It is also naturally found on and in many reptiles, and does not usually make the animals sick, but if passed to humans– particularly young children, the elderly and infirm — it can cause a serious infection called Salmonellosis.

But selecting the right anti-microbial was not as easy a choice as we thought it would be.

Food and Drug Administration published reports question the use of antibacterial soap and hand sanitizers, saying that it found no medical studies that showed a link between a specific consumer antibacterial product and a decline in infection rates. Plus, regular soap kills 90% of bacteria and leaves little impact on the environment.

Additionally, anti-bacterial products like Purell use synthetic polymers known as Triclocarban and triclosan to kill off bacteria. Triclosan is known to promote the growth of resistant bacteria, including E. coli, and both pose environmental toxicity risks; after washing your hands or washing the dishes they can get into the waste water system. Because they do not break down or get filtered out during waste water treatment, up to 75 percent of the original amount gets into the Bay. Once in the environment, these products have been known to disrupt the health of marine life and other wildlife.

So Academy scientists went in search of an alternative product that does not contain the above 2 agents, and has recommended Vionex Antimicrobial Soap for our public programs. Commonly used in the medical, dental, and law enforcement industries, Vionex uses a different antimicrobial agent called PCMX, or parachlorometaxylenol, which is considered significantly less toxic to humans and other mammals that Triclocarban and Triclosan.

What you can do at home

Even if you are not handling reptiles daily like we are, you can take action to reduce exposure to toxic anti-microbials. Whenever possible avoid products that are labeled “anti-bacterial.” Products that are likely to be anti-bacterial are most hand-sanitizers, hand wipes, cleaning products, and dishwasher detergent. If you must use hand-sanitizers, consider natural ones such as Hand-Sanz (found at Whole Food or Bristol Farms).

I admit it, I watch way too much television. Some good television (KQED QUEST for example), but mainly bad television: American Idol, Amazing Race, pretty much anything on the VH1 channel. My brain was turning to mush.

After some cajoling from the wife, I trekked down to the library to check out the science section. I was amazed at the bevy of great pop science books. Most are accessible, quick reads on pretty much every science topic under the sun. However, I'm a social creature, I wanted to discuss science books with peers.

A few quick searches and voila! Science book clubs exist right here in the Bay Area (one of them hosted by myself so I'd have more control on book selection). Lively discussion and science books, it's a good combination.

This Week In Science Online Book Club – Hosted by TWIS.org

An Ocean of Air: Why the Wind Blows and Other Mysteries of the Atmosphere

Details: Most of the time we hardly notice that we're moving through air. But when a storm system whips it into a whirling mass that grows into a tornado or a hurricane, then the air around us makes headlines. Science consultant Walker (Snowball Earth) presents a lively history of scientists' and adventurers' exploration of this important and complex contributor to life on Earth, from Galileo's early attempts to show that it has weight to the explorations by 20th-century scientists Oliver Heaviside and Edward Appleton of the ionosphere, which acts as a giant mirror bouncing radio waves from one side of the globe to another. Walker provides readers with easy-to-follow discussions of the science behind the discovery that carbon dioxide levels are rising exponentially.

Yuri Alexyevich Gagarin, "Columbus of the Cosmos" Last Thursday evening, over 3500 people came to the California Academy of Sciences to help celebrate Yuri. This gathering was not the only celebration of its kind. Two-hundred and eight parties in forty-six countries on eight continents celebrated Yuri's Night between April 6 and 12th of this year.  So who is Yuri and why does he deserve such accolades?

Yuri Alexyevich Gagarin was a Soviet cosmonaut.  He was the first human in space and is often referred to as "the Columbus of the Cosmos".   His spacecraft Vostok-1 orbited the Earth on April 12, 1961 for the duration of 108 minutes.   Yuri's Night, usually celebrated on April 12^th celebrates this historic first flight.

Yuri's Night also celebrates another April 12^th anniversary notable in the annals of space travel.  Twenty years after Yuri Gagarin's historic flight, the first NASA space shuttle flight, STS-1 was launched into space.  STS is short for Space Transportation System.  NASA names each flight STS with the chronological number after it.  STS-1 was launched on April 12, 1981; the shuttle orbited the earth 37 times during a 54.5 hour mission.

Since 1961, our interest in space and the exploration of its depths has magnified.  Recently NASA launched the Kepler mission.  On March 7^th, 2009, the Kepler Mission successfully launched from Cape Canaveral, Florida.  Kepler, which is a specialized telescope, was designed to find the first Earth-size planets orbiting stars within a "habitable zone". A habitable zone is an orbit around a star that would enable a planet to formulate and upkeep an atmosphere and the ability for water to form in pools on the planet's surface.  Liquid water is believed to be essential for the formation of life.  Thus from the nascent flight of orbiting our own Earth, space travels has evolved to look amongst other start.  This progress is certainly something worthy of celebration!

An exhibit on the Kepler Mission along with other NASA initiatives like SOFIA, LCROSS and NLSI fascinated guests last Thursday night.  For one guest, meeting Buzz Aldrin in person was the highlight of his night.   My favorite aspect of the evening was a 3-D rendered tour of the moon and neighboring space.  I am anxious to see what will be the new annal of space exploration when April 12^th and Yuri's Night comes around again in 2010.

The exhibits you see on the museum floor of the California Academy of Sciences are just the tip of the iceberg of the Academy's work. In fact, 90% of what we do is the education and research that happens behind-the-scenes. It is this ongoing research that in turn generates the exhibits and programming that guests enjoy.

The Naturalist Center, located on the 3rd floor, is a direct link for visitors to the education, research, and resources of the vast research collection that lies behind-the-scenes of the museum. Guests can ask questions at the Naturalist Center and they will get a reply from an Academy researcher or educator versed in that subject.

Below are some interesting questions guests have posed recently and the responses from experts on staff.

Q: How many copies of Darwin's "On the Origin of Species" were published initially?
A: The first edition and printing had a print run of 1250 copies. All the copies sold on the first day of sale according to "The Life and Letters of Charles Darwin".

Q: You have a specimen in your collections that is noted for being the most poisonous bird in the world. Do you have more information on it?
A: It is the Hooded Pitohui (Pitohui dichrous). An Academy researcher, Jack Dumbacher, experienced the toxicity of these birds first-hand when he was doing research in Papua New Guinea and decided to study them more. He found that they sequester poisons from something they feed on, much like poison dart frogs.

Q: Do owls really see in total darkness like your matching game says?
A: Renowned for their solemn, spooky mien, owls have large eyes that face forward, and arrangement that's rare even among predatory birds. This gives them binocular vision and the resultant depth perception necessary to judge distances with almost pinpoint accuracy. These fast-focusing eyes are also equipped with a mirror-like membrane that lets them sample extremely dim light twice, and a dense concentration of light-sensitive cells in the retina. While owls may not be able to see everything in total darkness, they can see what other nocturnal predators might miss.

Q: What is Arsenic and Strychnine made out of?
A: Arsenopyrite is an iron arsenic sulfide (FeAsS). Strychnine is an alkaloid extract obtained from the dried ripe seeds of Strychnos nux vomica, a small tree of the East Indies.

Q: Someone told me that the red-winged blackbirds only have that red flash in mating season – is that correct?
A: According to Western Birds, QL 683 .W4 P4 1990, these epaulets are 'most conspicuous' in the spring time, suggesting that they are there all year round but brighter in the mating season.

Q: Do you know that saying about claw and tail sizes of scorpions that tells you which ones are more poisonous than the other?
A: The simple, although not universal, rule is that scorpions with thin pedipalps (claws) and thick tails tend to be more venomous than those with stout pedipalps and thinner tails. Working through this in a logical way, we can think that a scorpion with a large claw may be able to subdue its prey with the claw. If it has thin claws, it may need to rely more on the venom from the stinger to make up for its lack of strong claws. For more information about scorpions, click here. There is also a very well written amateur information page here.

This week the Cal Academy of Sciences celebrated the millionth
visitor to its new building in Golden Gate Park

On March 3rd, 2009 at 1:00 p.m., executive director Gregory Farrington greeted the one-millionth visitor to the new California Academy of Sciences. It seems incredible that in just over five months, one million visitors have explored our new building in Golden Gate Park. Yet science museums and cultural institutions are incredibly important in these tough economic times: Museums engage and educate people about their place, culture, accomplishments and environment. With the cutbacks in education, museums are even more necessary.

Earlier this year, the California Academy of Sciences commissioned a national survey of basic science literacy, administered by Harris Interactive. The results proved poor. Here's a sample:

• Only 53% of adults know how long it takes for the Earth to revolve around the Sun.
• Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time.
• Only 47% of adults can roughly approximate the percent of the Earth's surface that is covered with water.
• Only 1% of adults knew the correct percentage of fresh water on the planet

Despite their poor performance, survey participants felt that science literacy and conservation were very important. Four out of five people surveyed marked science education as “absolutely essential” and directly related to the U.S. health care system, the U.S. reputation globally and the U.S. economy.

Scientists know that making new discoveries increases our understanding of our world and our place within it. Yet deepening science literacy in the general public is equally important. Scientific literacy not only engages potential future scientists, but it helps strengthen the U.S. economy. Analysts agree that science must be part of the plan for stimulating the American economy: A knowledge-based economy, including a focus on science, drives innovation, which in turn sparks new industries and subsequent jobs.

The Academy felt this survey was so important that they put the questions up on the website for anyone to try. What's your science literacy? Find out by answering the questions on www.calacademy.org.

Coco-de-mer, the world's largest seeds
Last Thursday, February 12th, was the inaugural evening of NightLife at the California Academy of Sciences, a weekly science evening for adults. It was also Charles Darwin's 200th birthday. To honor the father of evolution, Academy researchers unveiled Darwin's Carnival, a collection of curious specimens brought out from our collections, including Botany, Ornithology & Mammalogy, Entomology, Herpetology, Invertebrate Zoology, Geology, and the Library Archives.

There was a great variety of unusual specimens elucidating adaptation and evolution. One caught my eye, however, because I used to pass by it every day at our Howard Street location on the way up to my desk. I had presumed it was a cacao seed, but in truth it was a Coco-de-Mer, better known as the world's largest seed.

Coco-de-Mer, also known as "the double coconut", is the seed of the Lodoicea maldvica plant, a large fan palm that reaches 25 m (82 ft) in height. The palm is only found on two islands -– Praslin & Curieuse in the Seychelles. The palm is best known for the seed of its fruit, which is the largest in the world, weighing in at 15 to 30 kg (33 to 66 lbs).

The palm species was named maldvica after the Maldive Islands, the place the seeds were first found (before the 18th century the Seychelles islands were still uninhabited). Seeds that had germinated (and were therefore hollowed out) would find their way into the water, and prevailing sea currents carried a great many of them to the Maldives. The seeds were used by indigenous people on the islands for medicinal treatments and in trade.

Many stories abounded about the source of the seeds before the truth was discovered in the Seychelles islands in 1768. Many believed the seeds came from a mythical tree that grew at the bottom of the sea. European nobles would often have the Coco-de-Mer seeds cleaned and encrusted with jewels– befitting their mythical origins — in order to display them as collectibles in private galleries. Today, the Coco-de-Mer is still considered a treasure and the seeds and plants from which they grow are protected as a rare species.

On the public floor of the California Academy of Sciences is a direct tie into research and resources of many a variety and color. The Naturalist Center is located on the third floor adjacent to the exit from the planetarium. It is an often overlooked treasure. The Center offers a wide range of resources and services to individuals interested in learning more about the natural world. Academy visitors can walk in during open hours, explore the library, conduct research, and connect with staff members as well as other visitors.

Academy visitors can also ask questions about Academy exhibits or natural history. One day, when I was working in the Naturalist Center, a woman asked if squirrels eat bark and if so are they particularly fond of citrus bark? With a bit of research, we found out that some California-native squirrels indeed do eat bark and are fond of citrus trees. Below are some of the questions asked recently in the naturalist center, their corresponding answers as well as links to relevant fact sheets.

Q: Why is the green iguana orange? What do you feed it? (Visitor)

A: According to an Academy aquarium biologists, when males reach sexual maturity their coloring will turn orange. It's more hormonal than dietary, however diet can slightly influence color. The Academy has a male that is roughly three years old. He was rescued from a flea market as a baby in very poor condition. He is fed primarily greens (dandelion, collard, arugula) and small amounts of green beans, sweet potato, yellow squash, mango, berries, banana, papaya, cactus, and flowers along with a vitamin/calcium supplement.

Q: What is a hyrax?

A: A hyrax is related to the manatee and dugong and is the closest living relative of the elephant. More information is given on hyraxes in this fact sheet: www.awf.org/content/wildlife/detail/hyrax

Q: What is the wattage of the lights that are above the rainforest dome?

A: The electrician in the Academy noted that they are 1000 and 2000 watt bulbs.

Q: How much does the roof weigh?

A: It weighs between 2.7 and 2.8 million pounds not including the steel and concrete. More specific information is given on the Living Roof Fact Sheet: http://www.calacademy.org/newsroom/releases/2007/living_roof_fact_sheet.php

Q: How many African Penguins are in an average colony?

A: The number varies greatly and there is no true average. There are colonies with as few as 240 breeding pairs and one that was as high as 55,000 at one time. African penguin numbers have declined worldwide at an alarming rate in recent years. Decline in numbers is due to threats that range from oil spills to feral cats. Food availability and prime breeding territory are major factors in colony size as well. Today, there are an estimated 50,000 total breeding pairs worldwide. More information is given on African penguins in this fact sheet: http://combine.cs.bris.ac.uk/opencms/opencms/Richards_Homepage/My_Research/AfricanPenguin.html

Ball Python (Python regius)The majority of staff were "all hands on deck" this past Saturday and Sunday at the California Academy of Sciences. Yet, we were vastly outnumbered. Fifteen thousand people perused the new building while thousands more enjoyed the festivities in the park.

Two of us, with animal handling experience, were rotating handling of a a four foot Ball Python and a six and half foot Red tailed Boa Constrictor to give guests a chance to get up close and personal with nature.

However, not everyone loves snakes. I had stickers in my pocket for those kids who were too shy or scared to come and see the snake I had in my hands. But the majority of kids would approach unabashed and when I was on the floor with the Ball Python, I was often surrounded by "shorter" guests. As I was going through the Piazza, I was approached by a woman, her daughter, and with trepidation her husband. They were visiting from England and the woman and her daughter were enjoying petting the snake and were asking questions about it. The woman asked her husband to join in and I looked up to see the fear palatable on his face.

My mom, who was bitten as a child has a large fear of snakes, so I could read the fear easily on the man's face. I asked him about it and he said one of the reasons he loved England was its lack of snakes. Talking to him, I explained my mom's fear and why the snake I was holding was a great snake for him to pet if he would like to. At full growth, the Ball Python only reaches four feet. The Ball Python gets its name for hiding it head into the ball of its body when threatened, so a chance of being bitten by a Ball Python that is used to being handled is slight. This particular snake, was incredibly docile and had been handled for over ten years. He approached visibly shaking to pet the snake's body. Tears were rolling down his face, it was apparent that he was facing a life long fear. His daughter and wife were beaming at the exchange. It felt wonderful allowing someone to face a fear in such a safe and positive way.

Stories of moments have been shared amongst staff since opening weekend. All of these stories relate small moments exchanged between staff and guests. Some are funny, some touching. This is just my own story. The majority of Academy staff volunteered to work a ten- to fifteen-hour day each day in order to be part of the opening weekend. Staff coped with long days, tired feet, and answers repeated over a hundred times with a smile. They continue to replay opening with stories like this with each other. It is great to be open and I am looking forward to many more stories and shared moments.

Lately my whole focus has been on September 27, 2008. The last four years of my life as well as the lives of other staff at the California Academy of Sciences has been in preparation for opening day. It is now 38 days and counting until the Academy opens its doors once again and all those years of work can finally have a culmination. The building is a flurry of constant activity and I've decided to dedicate the next few blogs to highlight some of the activity behind the closed glass doors and the spot that has gotten the attention of staff the past few weeks has been the swamp tank.

The swamp tank was an iconic feature of the old academy complete with a seahorse railing. It has been recreated with some additional touches. There is now a viewing window from the aquarium level so guests have the opportunity to either look down at the swamp's inhabitants or get eye level with them in the aquarium. For months, we have seen this tank filled and drained to test water quality. Last week the tank was filled and readied for animals.

Two large coolers were brought in filled with water and specimens. A host of aquarium staff took turns catching catfish and crayfish out of the coolers and transplanting them into the swamp by way of ladder. The swamp tank has no entrance so the only way to get animals transplanted in the tank is either ladder or crane. The crane has been tested numerous times with weight bags for larger animals. Last week the crane transported live cargo for the first time. The alligator snapping turtles were given a physical on the floor, complete with cutting of toenails and then were hoisted into the tank by crane. As exciting as it was seeing the turtles and fish acclimate to their new home, staff came out in bunches before noon today to see the final additions.

Two alligators came in the back entrance of the Academy around 11am this morning. They were individually carted in wooden crates. The female was taken out of her box first with many aquarium staff on hand for safety. The Academy vet and animal health staff gave the alligator a quick physical and herded her back into the wooden box for final transport. Her box was then fitted onto the crane by half of the attending staff while the other half of staff readied the male alligator for his physical. The male came out fighting and it took quite a bit of staff to restrain him. Staff let out a collective yelp when seeing him, as he is an albino alligator and the white of his skin was striking.

After both physicals, the alligators were housed back in their crates & they were hoisted one by one into the swamp. An alligator handler was waiting in the tank to steer the crates and coax the alligator out of it once it was set down. He unhooked two of the ropes securing the crane and lifted up the back of the crate so each alligator could slide easily in to the water. The female went into the water with no hiccups but the male took more coaxing. Even with lifting the back of the crate, he wasn't budging initially. But with a steep incline for the crate, he eventually slipped into the water. Collective cheers and clapping occurred when both alligators were in the tank. The audience of staff had been safely watching the whole episode from the catwalks above the tank. All in all, the whole transport from truck to tank took two hours.
