2009 AAAS Kavli Science Journalism Awards

 
The American Association for the Advancement of Science has just announced the Kavli Science Journalism Awards for 2009. It's a very interesting group of winners. Among them is Carl Zimmer, who won in the category "Large Newspaper—Circulation of 100,000 or more."

Awards are nice, but the problem with science journalism awards is that they are decided by a panel of science journalists. What this means is that the awards are for good journalism and not necessarily for good science. As most Sandwalk readers know, I'm not happy with the way science is presented to the general public and my main complaint about science writers is that they don't do a very good job of getting the science right. (Many scientists aren't much better, but that's a different issue.)

If we are going to award good science journalism, don't you think that one of the main criteria should be whether the reporting is scientifically accurate? If you accept that premise, then the next question is who should make that call.

Take Carl Zimmer's articles for example. One of them was Now: The Rest of the Genome published in The New York Times in November 2008. This is an article about genes and genomes and the main point is that our concept of a gene is in trouble in light of recent discoveries in genomics.

Carl's article is better than most but it still misrepresents the modern status of a gene and the importance of phenomena like alternative splicing and epigenetics [Genes and Straw Men]. There's no doubt in my mind that Carl is the best of the science writers who could have written about this subject but I'm still troubled by the fact that the prize committee was probably incapable of evaluating the accuracy of the science in his article.

The award is sponsored by AAAS. What would be wrong with having a few scientists as judges?

From the press release ...

"The AAAS awards have long recognized the importance of high-quality science journalism across the board," said Cristine Russell, president of the nonprofit Council for the Advancement of Science Writing. "The Kavli Foundation’s decision to endow the awards is particularly important at a time when accurate, insightful writing about science is threatened by rapid changes in the media marketplace. The future of this program is now assured as a new generation of journalists tackles important science developments and their impact on society.

I don't know Cristine Russel but she's promoting these awards as examples of "accurate, insightful writing about science." I'd love to know who determines whether the reporting is accurate. How does she know they were scientifically accurate?

Monday's Molecule #143

 
Sometimes it's almost impossible to find an image of a specific molecule that honors a Nobel Laureate. This is another one of those times.

This spectacular photograph shows a particular kind of creature and its egg. You need to identify the phylum to which this species belongs and then use that as a clue to come up with an appropriate Nobel Laureate. Your answer should include the particular species that is associated with the Nobel Prize as well as the Nobel Laureate. Be careful, I want the modern name of the species—not the old name that was used when the Nobel Prize was announced.

Here's a clue. The Nobel Prize was awarded in the last century, not the current one. Here's another clue, outside of the Nobel Peace prize and the mini-Nobel Prize in Economics, this award is probably the biggest mistake that the prize committee has ever made.

The first person to identify the molecule and name the Nobel Laureate(s) wins a free lunch. Previous winners are ineligible for six weeks from the time they first won the prize.

There are six ineligible candidates for this week's reward: Joshua Johnson of Victoria University in Australia, Markus-Frederik Bohn of the Lehrstuhl für Biotechnik in Erlangen, Germany, Jason Oakley a biochemistry student at the University of Toronto, Dima Klenchin of the University of Wisconsin, Madison, Alex Ling of the University of Toronto, and Bill Chaney of the University of Nebraska.

Joshua, Dima, and Bill have all agreed to donate their free lunch to an undergraduate. Consequently, I have three extra free lunches for deserving undergraduates. I'm going to award an additional prize to the first undergraduate student who can accept it. Please indicate in your email message whether you are an undergraduate and whether you can make it for lunch. If you can't make it for lunch then please consider donating it to someone who can in the next round.

THEME:

Ginkgo biloba

 
Ginko biloba is the only living species in the division (phylum?) Ginkgophyta. It is a species of deciduous tree that's only distantly related to to the other trees that we see around us. Some taxonomists classify it as a gymnosperm but that's not a universally recognized classification. It's certainly not an angiosperm (flowering plant).

Ginkgo is often called a "living fossil" because it resembles plants that date from 270 million years ago. The term is misleading because, like other "living fossils" Ginko biloba has evolved considerably since the time of its similar-looking ancestors.

The trees are either male or female. I recently visited a beautiful example of a female tree growing in the yard of Frank Lloyd Wright's house in Oak Park in the suburb's of Chicago. The tree was full of "berries" (technically not fruit), which were about to drop. I'm told that the berries are edible but not very pleasant. They smell like human feces. (The pun is obvious ... don't bother. )

I wish I'd been there a bit later 'cause ever since I learned about Ginkgo I've wanted to taste the berries.

All of the trees in North America have been deliberately planted by gardeners. The one in the yard of the Frank Lloyd Wright house was already there when Wright bought the property in 1889. It's estimated to be about 160 years old. They don't grow very well in most parts of Canada.

I was under the impression that the tree is native to some parts of China but recent genotyping of the trees suggests that even those trees may have been deliberately planted there by ancient monks.

Charles and Camilla Are in Town

 
Charles and Camilla are visiting Toronto but you wouldn't know it if you didn't read the papers. Unless, of course, you just happen to be caught up in one of the mini traffic jams that are associated with such visits.

I witnessed one last night as several motorcycles and police cars with red and blue lights flashing, and sirens wailing, raced up University Avenue and around Queen's Park. They were escorting a convoy of half a dozen limos. I figure they were exceeding the speed limit by quite a bit.

Today, Charles is accompanying Camilla to Dundurn castle in Hamilton. The great house was built by Sir Allan Napier MacNab who happens to be Camilla's great-great-great grandfather. MacNab was Prime Minister of the Province of Ontario and was a member of the ruling elite that William Lyon Mackenzie opposed in the 1837 "rebellion."

This is Camilla's first visit to Canada. Charles has been here too often.

The couple will be opening the Royal Agricultural Winter's Fair before flying back to England.

For those of you interested in genealogy, here's how Camilla is related to MacNab.

Nobel Laureate: Lee Hartwell

 

The Nobel Prize in Physiology or Medicine 2001

"for their discoveries of key regulators of the cell cycle"

Leland H. Hartwell (1939 - ) won the Nobel Prize for his contributions to understanding the cell cycle. His discovery of the regulatory molecule CDC28 led to the idea of "checkpoints"—steps in the cell cycle where specific action is needed to progress to the next stage.

Hartwell shared the 2001 Nobel Prize with Paul Nurse and Tim Hunt.

Some of you may think that elucidation of the cell cycle in yeast isn't such a big deal. You would be wrong. No only did this work stimulate a huge field of study in yeast, but the genes and the pathways uncovered in yeast are similar to those in other eukaryotic cells. This is a case where fundamental basic science has lead to a deep understanding of how life works at the molecular level.

THEME:
Nobel LaureatesI already posted the press release under Nobel Laureate: Sir Paul Nurse. It's a very good description of the work that was done by all three Nobel Laureates.

Here's an excerpt from the Presentation Speech.

This year's Nobel Laureates have discovered the key regulators of the cell cycle, cyclin dependent kinase (CDK) and cyclin. Together these two components form an enzyme, in which CDK is comparable to a "molecular engine" that drives the cell through the cell cycle by altering the structure and function of other proteins in the cell. Cyclin is the main switch that turns the "CDK engine" on and off. This cell cycle engine operates in the same way in such widely disparate organisms as yeast cells, plants, animals and humans.

How were the key regulators CDK and cyclin discovered?

Lee Hartwell realized the great potential of genetic methods for cell cycle studies. He chose baker's yeast as a model organism. In the microscope he could identify genetically altered cells - mutated cells - that stopped in the cell cycle when they were cultured at an elevated temperature. Using this method Hartwell discovered, in the early 1970s, dozens of genes specific to the cell division cycle, which he named CDC genes. One of these genes, CDC28, controls the initiation of each cell cycle, the "start" function. Hartwell also formulated the concept of "checkpoints," which ensure that cell cycle events occur in the correct order. Checkpoints are comparable to the program in a washing machine that checks if one step has been properly completed before the next can start. Checkpoint defects are considered to be one of the reasons behind the transformation of normal cells into cancer cells.

Monday's Molecule #142: Winner

 
The diagram should remind you of the cell cycle and the 2001 Nobel Prize in Physiology and Medicine. Since I already covered Tim Hunt and Paul Nurse, this must be about Lee Hartwell. That means the molecule must be "start" or CDC28.

The winner is Bill Chaney of the University of Nebraska. He has agreed to donate his free lunch to an undergraduate. Unfortunately, there weren't any undergraduate who got the right answer this week so I still have three free lunches to give away.

---

Sometimes it's almost impossible to find an image of a specific molecule that honors a Nobel Laureate. This is one of those times.

The diagram provides all the clues necessary to identify an important process and then to identify a particular molecule associated with this week's Nobel Laureate.

You must name the molecule and the Nobel Laureate. Be careful 'cause it's easy to make a mistake and name someone who has already been the subject of a Monday's Molecule.

The first person to identify the molecule and name the Nobel Laureate(s) wins a free lunch. Previous winners are ineligible for six weeks from the time they first won the prize.

There are only six ineligible candidates for this week's reward: Frank Schmidt of the University of Missouri, Joshua Johnson of Victoria University in Australia, Markus-Frederik Bohn of the Lehrstuhl für Biotechnik in Erlangen, Germany, Jason Oakley a biochemistry student at the University of Toronto, Dima Klenchin of the University of Wisconsin, Madison and Alex Ling of the University of Toronto.

Joshua and Dima have agreed to donate their free lunch to an undergraduate. Consequently, I have two extra free lunches for deserving undergraduates so I'm going to award an additional prize to the first undergraduate student who can accept it.

Nobel Laureates: Archer Martin and Richard Synge

 

The Nobel Prize in Chemistry 1952.

"for their invention of partition chromatography"




Archer John Porter Martin (1910 - 2002) and Richard Laurence Millington Synge (1914 - 1994) won the Nobel Prize in Chemistry for their work on separating substances by partition chromatography.

The technique they developed was called paper chromatography but today there are many other, more effective, versions of partition chromatography. The example shown below is from Monday's Molecule #134 and it's taken from an article on paper chromatography.

In this example, a soluble extract of pigments from plant leaves is spotted at the bottom of a piece of paper and the end with the sample is placed in a suitable solvent such as a mixture of acetone and ether. The solvent rises up the paper by capillary action taking the dissolved pigments with it. The trick is to choose a solvent mixture where the pigments (or other compounds) are differentially soluble so they migrate at different rates and separate on the paper.

The theory behind partition chromatography is complex. It used to be part of graduate courses in biochemistry.

I still remember taking Chemistry 542 back in 1969 and learning about Craig's ideas of counter-current distribution. We even covered the Martin & Synge 1941 paper in the Biochemical Journal (Biochem J. 35:1358). I still have my notes.

And I still get anxious whenever I hear the words "theoretical plates."

Martin & Synge, and others, developed techniques for separating amino acids and this was the basis of the sequencing technology employed by Fred Sanger for determining the amino acid sequence of insulin.

Back in 1952 it must have seemed unusual to be awarding a Nobel prize for chromatography. That's why the first part of the Presentation Speech explains why the discovery is important.

THEME:
Nobel Laureates

Your Majesties, Your Royal Highnesses, Ladies and Gentlemen.

This year's Nobel Prize in Chemistry is awarded for the discovery of a method for the separation of substances from complicated mixtures.

How can it happen, one may ask, that something apparently so commonplace as a separation method should be rewarded by a Nobel Prize? The answer is that from the very beginnings of chemistry until our own time, methods for separating substances have occupied a key position in this science. Even today, in Holland, chemistry is called "Scheikunde", or "the art of separation", and even today some of chemistry's most important advances are linked to the invention of new methods for separating various substances.

Chemistry today is to a large extent concentrated upon the study of natural products, which are obtained from animals, plants, or even bacteria and other microorganisms. A starting material of this type contains a great number of widely varied substances, some simple, others more complicated. The first thing the chemist must do is to isolate the substances he is interested in from the material and prepare them in a pure state. The next step is, if possible, to identify these substances and find out what they consist of and how they are built up from simple constituents.

The first problem, the isolation, can indeed be difficult, as it is often a matter of preparing in a pure state substances which constitute only an extremely small fraction of the starting material and which have the disagreeable tendency of, so to speak, disappearing between one's fingers when one tries to get hold of them. It is here that Martin and Synge's method has enjoyed great success, especially in what is perhaps its most important form, and is called filter-paper chromatography.

A Confused Philosopher (Part II)

I've written a lot about Michael Ruse over the past few years. Mostly I'm upset by his lack of understanding of modern evolutionary theory [A Confused Philosopher, Down with Darwinism!, Darwinism at the ROM].

I'm also annoyed at the accommodationist position that Ruse takes from time to time and his support for the Courtier's Reply. He's one of those people who think that there are very sophisticated arguments for the existence of God—arguments that most atheists can't refute.

Ruse's latest foray into this philosophical mine field was just published in The Guardian: Dawkins et al bring us into disrepute.

It's a pile of crap but Jerry Coyne [Ruse gibbers on. . . .] and PZ Myers [Schisms, rifts, and apologia for insanity] have already proven that beyond a shadow of a doubt.

Ruse moved from the University of Guelph to a university in Florida so he could avoid mandatory retirement. Perhaps he should consider voluntary retirement?

Charles Darwin's Brave New World: A Dangerous Idea

 
I watched the first part last night on The Nature of Things with David Suzuki. It was pretty good, although the emphasis on how Darwin was afraid to discuss his ideas got a bit tedious.

I'm also skeptical about the film's claim that evolution caused Darwin to abandon religion. It's worth remembering that his father (Robert) and his grandfather (Erasmus) were well-known skeptics about religion and Darwin's brother, Erasmus, was not religious. Darwin hung out with a lot of people who were questioning religion even though they knew nothing about evolution.

Falling Back

 
Last night was the night we turned our clocks back one hour in Canada and the USA. It's easy to remember whether we lose an hour or gain an hour because even school children learn the phrase "Spring forward, Fall back." ("Fall" is the local jargon for "Autumn.")

For most people, this concept of adjusting your clocks twice a year is terribly confusing. Do you understand it?

Here's a short quiz to test your knowledge of time.

What do Australians do at this time of the year?

1. turn their clocks back one hour
2. turn their clocks forward one hour
3. don't adjust their clocks
4. who cares what happens in Vienna?

What is the astronomical reason for turning our clocks back one hour?

1. there is no astronomical reason for adjusting our clocks
2. the rotation of the Earth slows down when it nears apogee
3. there aren't exactly 24 hours in a day
4. clocks run slower when the Earth is farther from the sun

What happened last night in Saskatchewan?

1. people turned their clocks back one hour
2. people turned their clocks forward one hour
3. nobody adjusted their clocks
4. who cares what happens in Saskatchewan? (and where is it?)

If you normally catch the 7:33 commuter train, what will you do tomorrow?

1. take the 6:33 train
2. take the 8:33 train
3. get on the 7:33 train as usual
4. call in sick

What happens to the international date line at this time of year?

1. it moves 15° east
2. it moves 15° west
3. it stays right where it is but "midnight" becomes 1 AM during the winter months
4. nothing happens to the international date line

Did you ....

1. get one hour less sleep last night?
2. get one hour more sleep last night?
3. slept exactly the same amount as the night before
4. stayed up all night celebrating?

Mr. Big has an appointment to meet his accountant tomorrow at 12 noon. His secretary sent him an email message on Friday telling him that the appointment would have to be delayed by two hours. Mr. Big forgot to adjust his watch, so on Monday morning it was out of sync with the rest of the world. Assuming he got the email message, what time will he show up for the appointment according the adjusted clock in the accountant's office?

1. 11 AM
2. 12 noon
3. 1 PM
4. 2 PM
5. 3 PM

Which, if any, of the following count as valid and rational objections to daylight saving time, assuming it is properly implemented?

1. farmers will have to feed their animals in the dark
2. children will have to go to school before the sun rises
3. it wastes electricity
4. you lose an hour's sleep in the summer
5. it reduces crime
6. it disrupts international flight schedules
7. it's unnatural to adjust time
8. it causes health problems by messing with your circadian rhythm
