The Things Roos Do

February 8th, 2010

Little did you know that kangaroos have the power to save the world.

A recent press release in my email in-box tipped me off to the hidden super-powers of our bouncing animal friends from the land of Aus.

According to the press release, a study published in 2009 found that bacteria living in the guts of roos produce cancer-fighting anzymes. When tested in mice, injections of bacterial spores had 35-40% success in fighting cancerous tumors.

“In the labs, we train the bacteria, so they develop their innate ability to colonise tumours, digesting them, and stimulating the body’s natural immune system,” said Assoc. Prof. Ming Wei from the Griffith Institute of Health and Medical Research.

This study got me to thinking about what else I have heard about kangaroos through the science grapevine, and I remembered another amazing kangaroo ability that was uncovered back in 2007… kangaroos can fight global warming.

Well, it’s actually once again thanks to the bacteria that live in their guts that kangaroos have the fate of the world on their shoulders.

Most ruminants, animals with stomachs capable of fermentation, produce LOTS of methane. Methane is known to be a powerful greenhouse gas and a major factor in global climate change. Most of the methane released into the atmosphere related to human activities comes from our livestock. So, scientists are trying to figure out how to reduce the methane produced during the ruminant digestive process.

Back to kangaroos… kangaroos are foregut fermenters like cows, but it turns out that they don’t produce methane. The bacteria in their guts utilize a slightly different chemical process from that of other fermenting bacteria, and produce acetate as a bi-product instead.

Now that they have this interesting piece of information, scientists are on working on transferring kangaroo bacteria into cows. The problem they have to solve is how to get the bacteria to live in a stomach that is both anatomically and environmentally different from that of the kangaroo.

I wonder if it might be easier to get people to eat kangaroo.

TWISmas Tales

December 22nd, 2009

This year, we had a contest on This Week in Science. We gave prizes to the best holiday science poems, songs, or tales that minions created and sent to us. The winning entries are below:

A Visit From Kirk Cameron by Jason Quade
‘Twas the night before Twis-mas, when all through the lab,
Not a creature was stirring, not even a rat;
Post it notes hung by the monitor with care,
With hopes that my efforts would soon come to bear.

I drove home my car, while clearing my head,
My children were nestled all snug into bed,
Robo-wife in charging dock, I had a night cap,
And settled into bed for a long winter’s nap-

When out in the garden there arose such a clamour,
The Mrs. warm-booted and asked, ‘What’s the matter?’
Ran to the window and I could have sworn,
There was a tiny sleigh pulled by unicorns.

Cell phone in my hand as I dialed Nine - One - One
I knew in a moment it must be Kirk Cameron.
Creationist tunes seemed to play from a band,
But they came from Ray Comfort, a banana in hand.

More rapid than the progress of science they came,
They whistled, and shouted, and call’d unicorns by name:
“Now! Young-Earth, now! Old-Earth, now! Ussher, and Malign,
“On! Blinders, on! Pseudo, on! On Intelligent-Design;

A shovel my wife produced, I asked, “Why?”
She said that weak arguments would soon pile high.
“Scientific proof they claim to come by,
When they meet with an obstacle, they point to the sky”;

So up to the house-top Kirk Cameron he flew,
Propelled by hot air from the conclusions he drew.
As I put down my phone, and was turning around,
Down the chimney Mike Seaver came in with a bound:

A bundle of books was flung on his back,
And he look’d like a peddler just selling some crap:
His eyes - how they twinkled! His dimples how merry,
His cheeks were like roses, his nose like a cherry;

A wink of his eye soon gave me to know
This mid-night visitor would not readily go.
He tip-toed across, like a man who is mad,
And proffered a book which he laid in my hand.

His Hollywood mouth gave me the Heeby-Jeebies,
The book that he gave was ‘On the Origin of Species’
“Don’t worry he said”, with a sideways look,
“There’s nothing to fear in my little book.

We’ve prefaced the thing with lies near to treason
Sometimes you have to circumvent reason.
We took out the worst parts that put holes in our theory.
A chapter ….. or four. They were rather dreary.”

My hackles were up, but Violence wasn’t the solution
The poor Man-Boy needed an education in evolution.
And I said:
“Tis true Darwin’s book is of public domain,
To mar it with fairy tales, for that I say SHAME.

Individuals are variable, Variations are inheritable
Some offspring within a species are naturally perishable.
Survival and reproduction is for the apt and the strong,
And the history of the earth is very very long.”

When I finished he pulled his fingers promptly from his ears,
First I thought he didn’t listen, and then I saw the tears.
And it was at that moment that he had a choice,
He could embrace the science, do good with his voice.

Would his brain stay three-sizes-too-small that Twis-mas Eve
Or would he get excited, understand and believe?
He spoke not a word, but went straight to his work,
And ran out the window; it shattered, What a jerk!,
And laying his middle finger aside of his nose
He flipped me the bird, Ray Comfort was a-doze.

He sprung to his sleigh, children still in their beds,
His pony unicorns lost the cones from their heads.
But I heard him exclaim, ere they drove out of sight-
“Just because it’s not true doesn’t mean it’s not right!”
Dashing through Kigoma by Angela Heinz (sung to the tune of Jingle Bells)
Dashing through Kigoma
Chasing after chimps
Trying to find a fecal sample
So I can gather it.

Collecting all my data
Each minute that tick tocks
Man it can be grueling
But science really rocks!

Oh grad student, grad student
Making science waves
Working on some new research
For this TWISmas day.

Grad student, grad student
Future science nerd
Making sure the messages
Of evolutionary biology are heard.  YAY!
Darwin of TWISmas Past by Justina Pupkaite
I didn‘t want a lot for TWISmas,
There was just one thing I dreamed about,
I didn‘t care about the fossils
Or anything that science found –
I just wanted the red-bellied Claus
To slide my chimney at night
And turn me into a flying unicorn!
So I could join his deers in flight.

To my defense it can be said
That it was many years ago,
And nothing much was yet in my head.
But I had the desire to grow
Into a shiny flying unicorn!
And so I went to school to learn how
Only in the new light to be born
Into a scientist-to-be somehow.

And then the glorious star of education
Started shining like energy-save bulb.
I started following it with no vacation
For my hungry brain. I joined the club –
I followed Newton, Mendell and Einstein;
But still my dream lived on –
While all the knowledge was fine,
I wanted to be a unicorn!
But everyone would say
(Less and less patiently to a varying degree)
That there was no way!
But I needed the argument explained to me!
I was told that it was how people were created,
And nothing would ever change.
I thought that there were things to be debated,
But the bell rang TWISmas break.

And so I went home on the night before TWISmas,
Snuggled up in bed, and was fast asleep,
When I heard a whooshing sound, and sitting up
I saw the Grandfather Darwin from the deep
Of Christmas past. He explained
How species come to be and evolution works.
And I listened, my breath bated,
Waiting to find out if I could be a unicorn!
But Grandfather Darwin went on to tell
How every individual is born with slight variations,
And they survive more or less well.
Those that reproduce pass on their adaptations,
Which takes years and years and years.
And that is how species change and form.
The evidence is all around out there!
To survive you have to be strong
And to adapt to the conditions.
That is how useful traits remain:
Some have the predisposition
To become another‘s prey…

And so a new picture appeared
In my mind: species fell in their places
On the huge Earth family tree.

Grandpa Darwin vanished without traces.
I cuddled up and fell asleep,
Happy that it was all in my head.

What I Said…

December 11th, 2009

Just found this great post about a talk I gave in Modesto a couple of months ago. I have the audio from the presentation somewhere around here, so I’ll try to post it for y’all to check out at some point.

I love talking about science, and this venue in Modesto was great. The organizers were absolutely gracious, and I had the opportunity to meet several of the local science educators. There was a nice turnout with what seemed like a lot of enthusiasm for the topic.

Good times with science in Modesto, I tell you.

What’s Your Favorite Droid App?

November 19th, 2009

I just got the Motorola Droid, and am absolutely loving it. I may just be falling prey to the siren song of Google, but it’s a sweet ride into oblivion so far.

Do you have a Droid? What do you think? What are your favorite apps? Curious minds want to know…

Talking to You on Dr. Kiki’s Science Hour

November 5th, 2009

So, I’m trying something new on the Science Hour. The show was started with the intention of interacting with the audience (that’s the joy of live!).

Our first attempts were unsuccessful, but we are not dissuaged from our quest. We are going to try again using Vidly!

Vidly used to be Twit.Vid, and is a great way to share videos using Twitter.

TODAY!!! At 3pm Pacific, on DKSH I will have three questions, and I want to hear answers from you. I want to include your Vidly responses to the questions in the show.
Here are the questions:
1) What are your thoughts on the H1N1 vaccine? Are you concerned or not? Why? (Topic: Vaccine)

2) Do you think science has a PR problem? Or, is it just certain hot button issues? What do you think should be done about it? (Topic: Science PR)

3) What was your favorite childhood science project? Any science adventures you’d like to share? (Topic: Experiments)

4) Do you have any questions for me? (Topic: Questions)

Record your responses to one, two, or all of the questions using Vidly, using Twitter to broadcast it / them.

Make sure you use the hastag #DKSH and the question topic in the tweet, so that I can find it!

Get involved. I want to hear from you!

Dealing with Trolls

October 28th, 2009

This is how I deal with trolls commenting on my website (at least, today… strategy might change given time)…

Everyone, say hi to Paul! (This is his IP: 141.150.79.232) Paul left this wonderful comment for me recently. It left me feeling confused as to why someone / anyone would take the time to spew so much vitriol. It really makes no sense.

So let me get this straight… you’re 35 (although you look older), unmarried, childless, and very much involved with your “career”. If you continue on this trajectory, you will die a childless and miserable woman, and worst of all, you will have denied Western civilization (and this world) your progeny. It is because of women like you that whites will be an extinct group within a few hundred years. Your time is very near the end. Good luck with your meaningless career.

Hmmm… Glad to know that I am personally responsible for allowing white people to go extinct rather than it being a process of selection. Aside from that, I am quite happy, have wonderful friends and family, and look forward to my future, childless or not.

There is no room for personal misery when there is so much wonder in the world.

Communication Basics

October 28th, 2009

Today I co-led a media training session for scientists. The day went quite well, and I found it rewarding to be able to share my knowledge and experience with other scientists. I remember what it was like to learn about the media’s perspective on communicating science. It was so foreign to my science-trained brain, but understandable since it could be boiled down to one main point.

In communicating your work (whatever it might be) with anyone, you need to tell a story. To tell a story you need to be able to first draw in your audience, get them interested in what you have to say. Once you have them, you follow a story arc, feeding them supporting ideas and information to satisfy their interest. To tie it all up, you need a good ending that will leave the audience with a lasting impression.

In order to get someone’s attention, you should start by answering the question: “Why is this interesting or important?” Strangely enough, when you are immersed in the nuanced details of your work that is one of the questions that becomes the most difficult to answer. Think of the big picture and how the average person might be interested. What are the common human threads that can tie your work to something tangible?

The information that follows your story’s introduction needs to support that connection. Answering the question of “how” is fundamental here, but the story can’t get too bogged down in details at this point or you lose the interest of the audience. Think of the children’s story of the Three Little Pigs. When the big, bad wolf came to blow the house down all that you know about how he tried to do it was that “he huffed and he puffed.” You don’t need to know how many breaths he took or how large his lung volume was or whether or not he had asthmatic symptoms (although that might have changed the story a bit). The information given is enough to keep you engaged (”oh, man! He’s huffing and puffing!”) and wondering what will come next (”oh, man! IS he going to blow it down this time?”).

The story’s end is the place where you have your last chance to make an impression, if you haven’t already. I’ll continue with the Little Pigs example here, which ends with the wolf climbing on the third pig’s roof to get at the pig by way of the chimney. Instead falling down the chimney only to land in a pot of boiling water put there by the pig. The pig turns the tables on the wolf and end up eating him instead of the other way ’round. This ending leaves quite an impression, and ties up all the loose ends of the story (pig not eaten lives happily ever after, wolf is dead and can cause no further trouble).

In science, your ending can be a message you want people to hear or an action you want people to know about or do themselves. In either case, it helps to use strong words that elicit emotional responses that will make your message that much stronger.

There is lots more to communication than just the story, for sure. But, thinking about your work as a story to be told is a great place to start.

Science Word Association

September 30th, 2009


Wordle: Science Word Association

Once again, I have gone in search of reactions to the word ’science’. This time, instead of Twitter, I gleaned my results from the University of Florida word association database, which has been collecting people’s word responses since the 1970’s.

The relative strength of each word in this cloud I made at Wordle is based upon the number of people responding with that word out of a total of 126 respondents. These are the top 12 responses.
