Evolution of the Amino Acid Alphabet – biology colloquium on April 29

A talk about Aliens in Fresno!

But no… not my kind of aliens, them other kind… y’know, extraterrestrial! But… how would you know?


Department of Biology and
Tri Beta Biology Honors Club present

Would alien life resemble us, and how could we possibly know? Astrobiology, evolution and the amino acids

A public lecture by

Dr. Stephen Freeland

Peters Auditorium, UBC 191

Free and open to the public with free parking in UBC lot

Abstract: A fundamental challenge for astrobiology is to establish the relative contributions of chance versus predictability in the origin and evolution of life on our own planet. Thus, for example, all Earth-life creates metabolism from an interacting network of protein molecules that catalyze various biochemical reactions. Furthermore, early during evolution it had arrived at a standard set of 20 amino acid building-blocks with which to build each of these proteins. We now have good reason to think that many of these amino acids are formed in significant quantities throughout the galaxy – but so are many others – so would alien life be like us, and how could we possibly know?

You should feel so safe against all threats, my American friends!

And nice that the world has such a Big Brother! So the US alone spends almost 43% of the entire planet’s military budget! There had better be some serious extraterrestrial threat then, for the US to save the world… or who the frack are they fighting and why?

Here’s another graph, showing the more-than-doubling of US defense spending over the last decade:

Surely the military industrial complex never had it so good before the twin-towers were brought down by entirely non-military means. I feel so safe now… don’t you, my American friends (and daughters)? And surely, this had nothing to do with the disappearing surplus and rising record deficits the US has seen over the same period. Couldn’t be. Also, never mind that your health-care, your retirement, your union, and your job may be on the chopping block (if they aren’t gone already) because the rich and the corporations in this country must get more tax cuts – at least you’re safe from all those military threats looming large against the US! Do share if you know what those threats are that necessitate such an enormous military budget – 6 times that of the next big-spending nation!

Sorry Desert Tortoise. No room for you in Google’s Earth Day paradise.

Today is Earth Day, a once grassroots movement seeking to remind people to pay attention to the earth which has now grown to become a global event apparently “celebrated” by over a billion people – much of it courtesy of your neighborhood multinational corporations who have co-opted the day to urge you to buy more products at special discounts to “celebrate Earth Day”. They must mean “celebrate our collective destruction of this earth for profit and a few fun consumer products and gadgets”. Why, instead of actually going out and planting a tree today, you can enjoy playing Lorax Garden” on your iPhone! Download for free today!! After all, why bother getting your hands dirty in an actual garden when you can get virtual karma playing it on your smartphone. Surely that’s what the Lorax wanted us to do, no?

As part of these corporate celebrations of the once-grassroots movement, Google sports this image of an impossibly idyllic edenic paradise as their doodle for the day:

Media_httpstaticibnli_iugeo

Lovely, isn’t it? Pandas and penguins and tigers living in harmony with the corporate logo tastefully hidden amid the verdant scenery!

Unfortunately, Google’s vision of paradise has no room for the Desert Tortoise, the Joshua Tree, or the ancient mesquites and all the other poor denizens of the Mojave Desert, just a few hundred miles outside Google’s corporate office windows. You see, just last week, Google upped their investment in the “green” solar energy company Brightsource, pouring in another $168 million to support that company’s massive solar projects in the Mojave Desert. Never mind that the project is already killing endangered tortoises, destroying their habitat along with that of all the other denizens of the Mojave’s unique biodiversity. And never mind that this kind of concentrated power generation with associated transmission costs and losses is an outdated model for this century. After all, combating global warming by switching to non-fossil-fuel energy sources is the be-all and end-all of environmental movements these days, we are told. By none other than the Atlantic’s Alexis Madrigal, who thinks conserving land is just “boring” compared to using exciting new “green” technologies to destroy habitats! This massive solar power generation technology is so exciting, it seems, that even Science Friday invited Madrigal to celebrate it on their Earth Day broadcast – where Ira Flatow forgot to ask any questions about the ecological impact of putting massive solar plants in the Mojave:

What’s doubly sad this Earth Day is that Madrigal is not alone. Too many environmentalist nonprofits and activists have bought into this model of green technology. One that merely substitutes one kind of power generation for another “greener” one without questioning the whole model! Why must we generate power at such massive scales, entailing land degradation, transmission losses, and a host of other problems, rather than developing smaller-scale technologies for distributed power generation from rooftops and parking lots? Whatever happened to “small is beautiful“? And why not put larger plants, if they’re needed, in brownfields and other land that we’ve already severely degraded through our other uses instead of bulldozing tortoise habitat? After all, there is plenty of such land within California’s urban/agriculture matrix which already covers more of the state than the remaining desert patches. If Germany, not known for its bright sun, can generate a significant amount of its power from rooftops in a distributed model, why must the US have to destroy remnant habitats still containing biodiversity? And why is Google, a company once at the cutting edge of innovation, with a motto “don’t be evil“, a supposed champion of the open-source internet as a force for democracy, i.e., distributed power, now investing in concentrated large-scale power projects mired in the old models of centralized production and distribution?!

Why aren’t more environmental groups raising these questions? Why is it left to a handful of “useful idiots” like Chris Clarke and Solar Done Right?

More importantly, why are we not asking the more fundamental question: WHY ON EARTH DO WE NEED TO KEEP USING SO MUCH DAMN ENERGY??!! Why can’t we cut down on the energy we currently waste, become more efficient, and work on reducing our massive ecological footprint by using less power-hungry products?

Oh, I forgot… how can we ask these questions, when the corporations are dangling all that shiny new magical technology in front of us all the time? Bright shiny smart phones where we can go play the Lorax game… what were you going on about the environment for, mate?

Sorry Lorax. Sorry Desert Tortoise. Sorry Mesquite. And Sorry Earth. We’ve sold you all out for a few shiny baubles. Happy Earth Day.

Earth+Plastic, the Great Electron, and George Carlin

Having subjected you to my rant for this Earth Day, allow me to share my all-time favorite rant, by that maestro of all ranting, George Carlin, reminding us holier-than-thou environmentalists of our proper place in the grand scheme of things:

Sorry Desert Tortoise. No room for you in Google’s Earth Day paradise.

On arguments from ignorance and the failure of science to persuade us otherwise

Tyson is brilliant and entertaining as usual, of course, but how successful is he at persuading people to accept the science and find comfort in our ignorance instead of inventing explanations? Perhaps not a whole lot, given how prone we are to what Tyson here calls “brain failure”. Chris Mooney, in an excellent piece in Mother Jones, explores how these brain failures mean that even the best science may not be enough to persuade people away from their long-held irrational beliefs – even when those beliefs fail spectacularly! What a flawed species we are, and how precious is this candle in the dark we’ve invented called science…
