Quantum mechanics and Foosball? Credit: RickyDavid.

When I began this story, it seemed pretty simple. I'd heard that scientists at Lawrence Berkeley National Lab were working to mimic photosynthesis and create a man-made version of the process that could supply us with renewable energy.

The premise is to create a "closed-loop" energy system. Artificial leaves would use water, sunlight and carbon dioxide as inputs to create fuels like butane. Those fuels would be used for transportation or fuel cells. And by burning those fuels, we would produce carbon dioxide. The cycle goes on from there.

I never thought that quantum mechanics would enter the picture. That's what I discovered at the UC Berkeley lab of Graham Fleming. He says we have a lot to thank photosynthesis for. It produces the oxygen we breathe and is the basis for the entire food chain on the planet.

Fleming's lab is dedicated to understanding how photosynthesis works so well. And one of the things they've found is that plants are somehow tapping into quantum mechanics to improve their efficiency. It's pretty complicated – but with the help of the folks in Fleming's lab, they helped me understand it through, of all things, Foosball. Here's an audio version of it to help you out.

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.

Pacific Madrone

Marin will look Baja. Berkeley like Bakersfield.

That's the projection of climatologists for the end of this century, if global warming continues on its current path.

But in trying to determine what California's plant life will look like based on those projections, studies and computer models only go so far. Despite the dire warning raised by this recent plant-loss study, biologists say the reality probably will be a lot worse.

In trying to get your mind around the idea that two-thirds of California's endemic plant species will lose 80 percent of their range by the end of the century, there are two ways to look at it.

The first is that, well, plants will just be different. It's not as if we're going to have barren soil where plants are now. As climate changes and warms, plants will most likely shift to the north. If we're talking an 8.3 degree Celsius shift in the summers, that means a rise of about 15 degrees Fahrenheit during the summer. Desert plants would move into Bakersfield and the Central Valley, for example. And in the Bay Area, the climate would be more similar to Southern California.

So, one way to think about it is: Plants will migrate or shift to cooler climates, so our endemic plants wouldn't necessarily disappear – they would just shift north.

But there were many factors that were NOT included in the plant-loss projection. And, as study author David Ackerly says, they are sobering.

If plants migrate, where will they go, and how will they get there? They need a certain type of soil, a certain amount of water. Many times, they interact with and need the plants or animals around them to survive; for instance, the gooseberry might need an animal that likes its berries so that its seed can be spread. And they don't just get up and walk north. It's a long, laborious process that can easily be derailed.

During the last Ice Age, plants migrated a thousand miles, Ackerly says, over about a thousand years. So why can't plants here move a hundred miles in a hundred years? Let us count the ways.

So IF the soils are compatible, IF the entire ecosystem of plants and animals can successfully travel north, IF such sites as vernal pools can somehow be created in the north, IF those ecosystems can somehow leapfrog over cities, farms, reservoirs, roads, ranches and other developments and find a compatible area that doesn't already have a robust ecosystem, IF the slow-growing plants can somehow travel a mile a year for the next hundred years, then yes, you'll successfully have a new habitat in a different place farther north.

Biologists suspect that most endemic plant species in California will die, if climate change continues at the same pace. For instance, redwood trees could still be growing in California by the end of the century, because the adults are hardy – but scientists say it will be a forest of the "living dead," meaning that, if no seedlings can make it, those adults will be the last redwoods on earth.

And the plants that come in to replace California plants, they say, will be invasive species – more commonly known as weeds – the fast-growing Mediterranean-climate plants with light, airborne seeds that will take over a barren area.

That's different plant life, true. But it's unlikely, they say, that our madrone or bay ecosystems will actually be re-created a hundred miles away, unless we move them up there ourselves.

Do-it-yourself tabletop biosphere..Last season, QUEST TV went on a field trip to the Maker Faire to see some of the wacky do-it-yourself things coming out of people’s garage work shops. This season, we took Quest Radio Editor Andrea Kissack out to the Make Magazine Test Lab to tinker and experiment with some of our favorite DIY science projects.

We started with a Table-Top Biosphere, or as MAKE called it, a "Tabletop Shrimp Support Module" or TSSM. The whole idea is to create an entirely self-sustaining aquatic ecosystem within a completely sealed jam jar. If you do it right, your freshwater shrimp "aquanaut" will be able to survive for months without your ever needing to feed it or even open the jar. The ecological balance you create supplies all the air, filtering and food for all the creatures within the jar to survive in perfect harmony. If only the real world was this easy.

Here are the instructions to make your own table-top biosphere.

It's almost spring: time for sultry nights, birds, bees, renewal and the sweet promise of new love.

For us humans, that might mean flirty skirts, a new perfume, a dapper new hat or hip hair cut, all in the hopes of attracting a new, or very old and loyal, perfect mate. Plants also feel the call of spring and respond. They too show off their brightest colors, excrete their most seductive scents and attempt to lure a mate. Of course, plants can't move (very quickly), so they hire a pollinating partner, and pay them to assist with reproduction.

Pollination is the act of moving pollen from the male anther to the female stigma. Plants work hard to attract these pollinators, and nectar is their delicious reward. Plants and their flowers take their job of attracting so seriously, that they have evolved to become irresistible to their pollinator. Pollinators, in turn, have adapted to a particular plant. Some of these Co-evolved partners have become so exclusive, that one could not survive without the other. Thus, attracting that pollinator is vital. Perhaps, with these tricks of attraction, we can all have a successful spring!

Like some humans, snapdragons have stooped to trapping. As an unsuspecting bee, just interested in a good dinner, sits on a lower petal, their weight causes the stamen to tip downward and dump dusty pollen on the bee's fuzzy body to carry onward.

The honeysuckle takes advantage of those who prefer the nightlife. Nocturnal moths are turned on by the pale white flowers that glow in the moon light and the alluring nighttime scent.

The African Raflessia flower knows that their partner has an unusual fetish and radiates a once-a-year stench of rotting flesh. Its petals peel away, revealing a brownish, fleshy color and the smitten flies come at once.

Queen Anne's lace takes pity on pollinators with short proboscises (ahem…) and offers pollen at the base of their tiny flowers, where bees, ants, wasps and beetles can easily dine.

The columbine flower offers very potent nectar in a bright, red, long flower: perfect for the active hummingbird with their long tongue and penchant for the color red.

In Madagascar, The 40ft Travelers Tree attracts the black and white ruffed lemur to climb the trunk, pull apart the flower bracts and stick their snout and tongues deep inside the flower. Nobody could do it better.

The agave plant works hard to attract the long-nosed bat with its night-blooming, tall flowers and strong nectar. (So if you were planning on a date that included tequila, you and the agave may thank a bat).

Now, why should we care about all of this wild romance? One reason is that one out of every three bites we take comes from a pollinated plant. Another is that without pollinating partners, we would miss out on such aphrodisiacs as strawberries, blueberries, garlic and chocolate.

So this spring, on your next dinner date, thank a pollinator for the delicious meal and know that the plants and I wish you the best of luck and love.
