Solar Showdown: How Well Do You Know Our Sun?

Many of us take the sun for granted, giving it little thought until it scorches our skin or gets in our eyes. But our star is a fascinating and complex object, a gigantic fusion reactor that gives us life. How much do you know about the sun?

One plant yields 3 clues to biofuel crops

The analysis of gene activity by researchers at Iowa State University and determination of protein structures by scientists at the Salk Institute for Biological Sciences independently identified three related proteins that appear to be involved in fatty-acid metabolism. The researchers used thale cress (Arabidopsis thaliana) as the model plant.

The research groups then joined forces to test this hypothesis, demonstrating a role of these proteins in regulating the amounts and types of fatty acids accumulated in plants.

The researchers also showed that the action of the proteins is very sensitive to temperature and that this feature may play an important role in how plants mitigate temperature stress using fatty acids.

The discovery is published online in the journal Nature.

“This work has major implications for modulating the fatty-acid profiles in plants, which is terribly important, not only to sustainable food production and nutrition but now also to biorenewable chemicals and fuels,” says corresponding author Joseph Noel, a professor and director of the Jack H. Skirball Center for Chemical Biology and Proteomics at the Salk Institute and an investigator with the Howard Hughes Medical Institute.

“…If you look at it, you see a dot. That’s here. That’s home. That’s us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam.

The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It’s been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we’ve ever known.”

8 Myths About Scientists

I stumbled across this in Thick Books and Thin Films by Adam Ruben. Pretty good.

Myth #1: Scientists frequently make “breakthroughs.”

Truth: Scientific discovery is agonizingly slow. The only time I’ve ever run naked through the streets yelling “Eureka!” is when I forgot to refill my prescription.

Myth #2: Scientists work in isolation.

Truth: Scientists are even prouder of setting up collaborations than they are of actual results. Most scientific talks end with a slide listing all collaborators like little badges of honor—and the less similar the collaborator’s field, the prouder the scientist. “Well, you know, I might have discovered a cure for tuberculosis,” a scientist will say, “but what I’m really excited about is this new collaboration with an Icelandic poet!”

Myth #3: Scientists possess useful skills.

Truth: Scientists possess useful laboratory skills. But you should never allow a physicist to wire your house.

Myth #4: Scientists follow the scientific method as it was taught in high school: Observation, Question, Research, Hypothesis, Experiment, Conclusion.

Truth: In reality, the way scientists work is more like: Fiddle Around, Find Something Weird, Retest It, It Doesn’t Happen a Second Time, Get Distracted Trying to Make It Happen Again, Go to Chipotle, Recall the Original Purpose of Your Research, Start Over, Apply for Funding for a Better Instrument, Publish Some Interim Fluff, Learn That Someone Has Scooped You, Take Your Lab in a New Direction, Apply for Funding for the New Direction, Collaborate With an Icelandic Poet, Eat Chipotle With an Icelandic Poet, Co-Write Scientifically Accurate Ode to Walrus, Get Interested in Something Unrelated, Apply for Funding for Something Unrelated, Notice That 20 Years Have Passed.

Myth #5: Experiments always yield data that teach or reveal something.

Truth: Let’s say you’re doing an experiment with five mice. These particular mice will turn either yellow or blue. So you walk into the lab expecting to see five yellow mice, which will point to one explanation, or five blue mice, which will point to the other. Instead you would see one yellow mouse, one green mouse, one striped mouse, one plaid mouse (dead), and one mouse that has somehow sewn himself a little blue jacket, though he doesn’t wear it all the time.

Myth #6: A personal tragedy can turn a scientist evil.

Truth: Very few scientists are legitimately evil, though the number rises if you ask graduate students to characterize their advisers. Besides, it’s hard to be truly evil when you don’t have any practical skills.

Myth #7: A scientist can be proficient in all branches of science.

Truth: Exactly what discipline did the professor from Gilligan’s Island specialize in? Chemistry? Mechanical engineering? Coconut-based transistor radio construction? Any time a problem needed solving or a device needed building, the professor knew exactly how to do it. That guy could make anything. Except a boat.

People who don’t understand science assume that scientists can master any subfield. That’s why we’re often asked for our opinions about scientific news items, and we can only reply, “Uh … sorry … I know I’m a molecular phylogeneticist, and this story was about molecular phylogenetics, but, well, I’m a different kind of molecular phylogeneticist.”

Myth #8: Scientists are not sexy beasts.

Truth: Scientists are indeed sexy beasts. Not only do our lab coats make us look dapper and charming, those same coats look even better strewn unceremoniously over a standing lamp while we make passionate love to you.
