The big announcement 2012
OH: "We can just have physicists on in the background…"
Tuesday does Saturday right: Our big screen shows physicists filing in slowly to take seats for the big Higgs-Boson announcement #nerds #yes
OMG. Physicists are cute. #higgsboson
Default for male physicists seems to be blue shirts, for females red. Does this mean female physicists are moving faster away from now?
Physicists. Sooooo cute and funny. #higgsboson #nerdsRgreat
Quickly becoming incomprehensible to me, but STILL CUTE! #higgsboson
Loving the messy, non-definitiveness of science. Slow growth of understanding & growth of subsequent questions. Thank you, scientists!
Trying stuff no one's done before? Science does that. 2012
"Nobody thinks to raise baby ostriches in the middle of a museum."
At @calacademy again. Yay!
These chicks are about 2 weeks old. Since they're the same ones I saw a week ago and the scientist in the rear of the photo said they'll be too big for the enclosure in another 4 weeks and that they have the next batch of eggs incubating now, I recommend a visit between June 25th and July 5th for optimal cuteness, either of the gangly teen or teensy fluffy baby variety depending on your luck and the accuracy of my memory of what he said.
The scientist bending over is using a small thermometer to test the temperature under the heat lamps. Baby ostriches are sensitive to heat and humidity and they like it about 95 degrees under there. The scientists are adjusting the height of these new lamps for optimal conditions.

A lovely visit to the museum 2012
Having a great time at @calacademy. The new Earthquake exhibit is excellent--especially the shake room! Members only today; public tomorrow.
New planetarium show at @calacademy is super cool, esp. for fans of #SF. Fly-through of bay in 1906 is entrancing & intriguing. #earthquake

sexism is a negative economic force 2012
"There is a lot still of unthinkingness and I have to say this is in the UK. This programme will go to many countries, particularly in southeast Asia, where there aren't these kinds of issues; where it's perfectly normal for women to do engineering, physics, science, what have you. But, it's a cultural thing and the English-speaking countries in particular tend to be on the poor side."
"Why is that?"
"It's something to do with cultural history. It may be something to do with defensiveness by the males. But what has happened, I judge, in southeast Asia for example, is the government has seen they need all the scientific and engineering talent they've got, so they make sure that it's perfectly okay for women to do science and engineering. And it shows."

A non-health takeaway from this one: Corporations (or as more benignly referred to, "brands") will be analyzing and acting on our social activity in staggering detail in ways that are not automatically or even always possibly perceptible to us. Individual rights now and in the future will require people with an understanding of the technology and techniques of analysis who are working on our side.

"The time has come to stop thinking of sub-saharan Africa as one place. Their countries are so different and they merit to be talked about in the same way that we don't talk about Europe as one place. I can tell you that the economy in Greece and Sweden are very different."
It's bigger than that, though:
"There is no such thing as a Western world and Developing world."
"You can clearly see the relation with falling child mortality and decreasing family size."
"Almost 50% of the fall in child mortality can be attributed to female education."
It's this kind of tight focus on the actual data—on what really works—that makes me love and respect Hans Rosling. It also reinforces my commitment to only vote for presidential candidates who place a high priority on the family planning and female education efforts which will drive that reduction in child mortality while at the same time slowing population growth.

"The letter was filled with no less than six serious errors regarding the science, data, and facts of climate science. The errors, in turn, exposed that the signers had confused their fame and/or their expertise in unrelated fields with expertise in climate science. And in response, NASA’s chief scientist politely suggested that the letter’s authors and signers should publish any contrary hypotheses and data in peer-reviewed scientific journals instead of trying to censor the publication of scientific conclusions from NASA climate scientists."

Great writing 2010
"The most unmistakable chemical transformation is that of a matter's state – a solid liquefies, a liquid evaporates, a vapor condenses into rain. For most of the furnishings of our everyday life, we associate a particular substance with only one of those three states. Wood, steel, and stone – solid. Oxygen and helium – gas. Alcoholic beverages – liquid (you can keep a bottle of Bombay Sapphire in the freezer, and somehow it remains an ever pourable starter to a gin and tonic). Water again bucks convention and seems almost equally at home in all three forms, as ice, steam, and liquid. In fact, Earth is exceptional in its possession of tristate water. Mars has a lot of water, but it's frozen away underground. Jupiter and Saturn have traces of water, too, but as orbiting ice crystals or a gas among miasmic gases. Only on Earth are there ocean flows and Arctic floes and sputtering Yellowstone fumaroles; only the Goldilocks planet has water to suit every bear."

Cool TED talk on animal & robot feet. Geckos' feet do utterly amazing stuff and octopi are more clever than I realized.
Tasty, tasty science 2007
As you may have read here before, I like me some science when I'm commuting or doing dishes - the two main times I put on my iPod and listen to podcasts.
Scientific American continues to deliver the best stuff, both in their short 60-Second Science daily series and in the longer Science Talk episodes.
Now you science-phobes stick with me here. The more you know about how living creatures reproduce the more entrancing the world becomes.
My favorite episode of the ones I've been catching up with has a great piece with University of Wisconsin evolutionary biologist Sean Carroll on the role of gene duplication in evolution. Totally cool stuff.
First, some background: all living creatures have molecules of DNA in their cells. DNA carries genetic information which controls the traits of the living creature. To quote Wikipedia, a gene is a hereditary unit consisting of DNA that occupies a spot on a chromosome and determines a characteristic in an organism. Genes are passed from parent to child in sexual species through the combination of genetic material from each parent. This process is called meiosis (pronounced my-oh-sis).
You've probably seen a diagram of DNA which looks like a long zipper. What happens in meiosis (in simplistic terms) is that each of the parent zippers gets unzipped and zips back together with the other half of the other zipper, so you get the mother's and father's DNA getting hooked together. What happens in this process is genetic recombination and that is an opportunity for change since the parents' DNA will not be identical. In other words, meiosis and sexual reproduction produce genetic variation.
What that means is that the living creature could have traits or behaviors which are different from its parents and/or from the offspring of other creatures of the same kind.
And what that means is that it might have a better chance of surviving (or at least breeding) in its particular environment. If so, it becomes more likely than those other creatures to pass its genetic material on to its own offspring. Multiply this by hundreds or thousands of generations and you've got survival of the "fittest". By "fittest" I mean the most able to survive (or at least breed) in a particular environment. It's not "best" - there's no goal or ideal here; it's just what currently, under these conditions works.
As you can imagine, migration of a creature into a new area can introduce new genetic variation in the population - the gene pool, if you will - of that area.
The last but certainly not least factor in genetic variation is mutation. Again to quote Wikipedia, mutations can be caused by copying errors in the genetic material during cell division [including meiosis!], by exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses, or can occur deliberately under cellular control during processes such as hypermutation. The resulting changes can be small or large - even as large as complete duplication of a gene - and may or may not have any effect on the creature's traits or behaviors.
If a mutation makes a creature less successful at surviving and/or breeding, it's less likely to pass on its genetic material to future generations. If the mutation is beneficial - i.e. improves the chances of survival and/or breeding - the genetic change is more likely to be passed to another generation. Note that a mutation doesn't need to otherwise benefit the creature to be beneficial to the continuation of that genetic pattern; it's all about reproduction.
The overwhelming majority of mutations are neutral; they have neither effect and may even be repaired by the cell. In many cases, though, these genetic changes are simply passed on through the generations doing neither harm nor good to the genetic "fitness" of that creature.
Which brings us back to this cool podcast.
when gene duplication was first noticed and realized to be important, most researchers thought that what it did was give you one copy of the gene that could continue performing its original important function, and another copy that natural selection could then experiment with to find a new function. But in your paper you talk about the fact that it might be the case that both genes wander off to find new functions.
Rather than my summarizing it, go give it a listen or read the transcript. It's totally cool and really well explained. Genetics are so neat!
(And if you want to learn more about molecular biology, I recommend Dr. Zach's Evolution 101 podcast. Pause the playback of the current episode (grrr) and scroll down to episode 108 "Molecular Biology Primer". Good stuff, which, because of when I first listened to it, I now probably irrevocably associate with doing a jigsaw puzzle in the Egyptian House in Penzance, Cornwall.)
Mmm, science and skepticism. 2007
I've got some good podcasts episodes from my many subscriptions for you today.
I've really been enjoying Point of Inquiry. Check out these two interviews:
Garrett G. Fagan - loads of fun hearing this author of Archaeological Fantasies: How Pseudo-archaeology Misrepresents the Past and Misleads the Public rip apart a whole bunch of false science about the past. This one is worth it for the incredibly long litany of proposed locations of Atlantis alone.
Peter H. Gilmore - this was a very surprising one. Turns out the Satanists don't believe in Satan as a god. Also, they call themselves a religion without believing in the supernatural at all. And their high priest turns out to be quite charming in interviews. I'm not drawn toward their church, but this interview cleared up lots of assumptions I'd made.
From the Science & the City podcast, this session with Oliver Sacks reminiscing fondly about his favorite parts of the table of chemical elements is just plain sweet.
A more recent session from this one was Alan Walker on the Search for "the Missing Link". Yum! Physical anthropology!
I've unsubscribed to a couple podcasts that I mentioned before, Science Update Podcast weekly edition (too fluffy) and This Week In Science (too much like annoying morning talk radio shows like Sarah & No Name on Alice), and subscribed to a new one, The Skeptics Guide To The Universe.

"Where you decide to put your time and attention says a lot about who you are." 2007
That's what Merlin Mann said in a great recent lecture at Google which he's kindly made available as part of his Inbox Zero series of posts.
So I was thinking about that, as well as the good practical email management advice from his talk, and I realized that one thing I really care about is science. But I have not been investing a proportional amount of my time into science compared to my interest in it.
I thought "Where do I have room in my day to fit in some science without pushing out something else that also matters to me or which I choose to make important in order to pay my bills and have some sort of career?"
And hello again, cute pink 4gb iPod which was a present from my friends Edmond & Shannon a few years back when they shared my place while escrow on their place cleared. I'd been neglecting it and only remembering about it when I was on the bus next to some incredibly banal and annoying conversation - usually one side of a cellphone conversation at that.
I'm now subscribing to a whopping 10 new podcasts in addition to the lovely 60-Second Science which I had already been enjoying on my laptop. And boy do I listen to them! Somehow even though my brain is sick of email and articles by the end of the workday (or in anticipation of it), listening to even fairly complex discourse is thoroughly enjoyable.
I've signed up for
- NOVA scienceNOW
- Ockham's Razor (the August 5th piece on Abolishing Weapons of Terror was very good)
- Point of Inquiry
- Science @ NASA Feature Stories
- Science & the City (from which I particularly enjoyed last Friday's episode with Alan Walker on The Search for "The Missing Link", a really top-notch ramble through physical anthropology. Highly recommended!)
- Science Friday
- Science Talk: The Podcast of Scientific American (and now I will out myself as a new huge admirer of Steve Mirsky's writing/delivery, both when he's seriously sharing knowledge and when he's barely restraining his sarcasm on, for example, people who play the lottery & their understanding of probability </fangirl>)
- Science Times
- Science Update Podcast weekly edition
- This Week In Science
You can get all these, as well as Merlin Manns 43 Folders podcast and They Might Be Giants podcast (my other subscriptions) most easily through iTunes, but you can also download them from some website somewhere, no doubt. Google is your friend in need for that.
What do you love? Go fit a little more of it into your otherwise idle moments and get reconnected.
And if you love science too, and have recommendations for more good podcasts, please share them in the comments.

Check out this cool animated map of earthquake activity around the world that my Uncle Larry sent me a link to!
Wouldn't it be great to have a 10 foot long version of this on the wall at a school?
Hmm, actually... wouldn't it be cool to have a giant screen like that which could provide visual data of dynamically changing factors affecting whatever the current study topic at a school was? And of course, putting it on a big screen on a wall is actually the no-brainer step after you make the maps available online so they can be on everyone's home page during that class. Interesting.

Excellent commentary on NASA's manned space activities from Maciej Ceglowski: Rocket to Nowhere. This was recommended as a must-read article by Jason Kottke and he's quite right. I hope every member of Congress reads this.
Personally, I would like to see the United States reallocate the manned space "exploration" funding to an even split between direct funding for more primary school science & math teachers & classroom materials and an increase to the budget of our highly successful unmanned activities. Maybe in 10 or 20 years it'll be time to think about sending humans off-planet again, but the decision must be driven by scientific reasons not national propaganda goals.
