Where For Art Thou Meteorite? – Meteorites that landed here on earth are more like the space rocks in the asteroid belt between Mars and Jupiter than like low metal content LL chondrite asteroids found closer to the earth.
Something Like a Comet – Researchers using the Sloan Digital Sky Survey reported finding a comet-like object in a 22,500 year orbit around the sun. It doesn’t have a comet tail because it never gets close enough to the sun.
How to Get There - Theoretical physicists have come up with a new idea for space travel. They suggest manipulating dark energy through another dimension of space, shrinking space in front of a ship and expanding it behind. The trouble is that it requires a quantity of energy equal to converting something like the planet Jupiter into pure energy.
Entangled particles really are “spooky” - Nothing travels faster than light, but two entangled particles separated by 18 kilometers and located in two different Swiss towns were able to communicate with instantaneous precision, thereby validating quantum mechanics and spooky action at a distance.

Nanotubes Are Strong - Experiments at Northwestern University proved that carbon nanotubes really are as strong as calculations predicted, and that radiation makes them even stronger. I’m still waiting for that space elevator.
A Limit to Tall - Physics imposes a limit on the height of trees. The maximum height to which Douglas Firs should be able to transport water is between 131 to 145 meters. That’s also the limit of their height.
Nature is the Best Teacher - Scientists mimicked photosynthesis in the lab, and were able to split water into hydrogen and oxygen using the power of light.
Asphalt into Energy – Hot asphalt roads and parking lots may produce energy one day. Scientists are experimenting with the idea of adding a heat exchanger that would convert the heat absorbed by asphalt into energy.
Planet Friendly Paper Coating - A replacement for the waterproof wax coating that’s used on paper products like drink boxes has been created from the lignin of sugarcane, which unlike wax leaves the paper it coats completely recyclable.
The Effect of Climate change – A recent study found that 9 out of 10 tree species measured in the Santa Rosa mountains of California have increased the elevation of their habitat by 213 feet. The change in growing range was linked to changes in local climate.
Antarctica is not Alone – Ice cores revealed that West Antarctica is highly affected by atmospheric and oceanic changes in the tropics of the Pacific Ocean.
Dead Zones of the World - The number of oxygen poor dead zones in the world’s oceans has doubled to 400 in just the past two years. These dead zones are linked to algae blooms fed by fertilizer run-off, sewage, and the burning of fossil fuels.
Filed under The Science Word, Uncategorized | Comment (1)Science Word Needs A Logo
After receiving the comment below, I changed my mind about having an official contest. I think contests are great and all, but I don’t want to be a part of the problem.
I need help creating a logo for The Science Word, the new video series that I’ve been playing with the past couple of weeks. I think it would do well as a vid-cast, and need some help making it come to life.
So, since I am terrible at graphic design, I am holding a contest asking for help to create The Science word logo. I know that there are people out there with amazing abilities. Send me something that can be the face of The Science Word to the world. If you have any ideas, or would like to help just because you’re nice like that I’d love to hear from you. I can’t pay cash money, and if I could it wouldn’t be much, but I can pimp the hell out of you and your work.
The contest starts today, and the deadline is next Friday, August 23rd.
If I pick your design, you will get all credit for creating the design, and I will pimp you like crazy on this website and all places related to The Science Word.
Send your logo designs (300 dpi and 300 x 300 min. size) to
Please, email me at kirsten at this week in science dot com.
Filed under The Science Word | Comment (1)This Week’s Science Word Videos Are Out!
I’ve published another set of Science Word videos… the science headlines in brief. Here’s the first of the set of four:
Hubble Space Telescope - What’s up in space, travels 5 miles per second, and has offered us an unparalleled view of our universe? The Hubble Space telescope, which just passed 100,000 times around the planet.
Size Doesn’t Matter - In nanotech, it’s apparently not the size of the particle that determines cell penetration, but the shape. Rods do much better than spheres.
Invisibility? - Harry Potter might have worn invisibility chain mail instead of a cloak if J.K Rowling had been paying attention to science. Researchers have created a new metal material that bends light backwards through electromagnetic interactions with the light istelf.
Large Hadron Collider - The Large Hadron Collider will officially begin operations on September 10th, but won’t get to full strength until sometime next spring.
Bicycle Saddles and the Police - The results are in… bike seats without noses keep bike cops frisky. Cops testing the special saddles had less genital numbing and better penile sensation.
Is Infertility Treatment Worth It? - Intrauterine insemination was only 6% more effective in producing a live birth than no treatment at all in a group of 580 women experiencing unexplained infertility. However, women who had insemination felt more reassured during the process.
Females Are The Same - Sexual harassment doesn’t just bother human females. It also bugs female guppies who tend to prefer the risk of being eaten to hanging out around pushy males.
Complete Neanderthal Mitochondrial Genome - The most complete and accurate Neanderthal mitochondrial genome to date was produced from a 38,000 year old fossil. Whether or not humans and Neanderthals ever got jiggy wid it is still in question.
A Pill For Alcoholics - Researchers in Oregon are testing a drug called CRF 154,526, which blocks all of the good, but none of the bad effects of alcohol– none of the euphoria, and the hangover’s still waiting. They say CRF is meant for treating hedonistic dysregulation.
Gene Link to Smoking Addiction -
People who say they got hooked on the first puff of a cigarette are likely to have a gene variant called CHRNA5.

Filed under The Science Word, Uncategorized | Comment (1)Evolving Landscapes
Two articles today got me thinking today (because you know I wouldn’t have been thinking otherwise).
The first, from SF Gate, described the recent decision allowing the University of California to reject high school credits for courses using textbooks that don’t meet the accepted admissions standards. Rejection of course credits can ultimately block the admission of students to the University.
It’s too bad that some students can be kept from attending a school because of decisions that their teachers and school boards make. However, admissions standards are used for a reason, namely to be sure that students are prepared for the next level of their education. And, if a student has been taught inadequately it will at best be difficult for them to do well within the university environment. Allowing such students entry to a university would be a disservice not only to those students, but to the university environment as a whole.
Unfortunately, the case in question is being turned into a religious freedom issue rather than the simple matter of standards that it really is. The textbooks being rejected leave out evolution in favor of Creationism or focus on “supernatural” causes/events. The plaintiffs in the case argue that these texts aren’t incorrect, they just present an alternative view of science and/or history.
Ok, so if that’s the case, I should be able to start a school that teaches only from texts promoting the history and science of the Flying Spaghetti Monster and Unicorns. Or, maybe I teach my home-schooled kids from texts that contain the history of the human race as being cultivated by aliens. Either way, I should expect that my students will gain entry to the UC system as long as they have good grades (and test scores, and of course, the appropriate extra-curricular activities).
It seems like the plaintiffs have the following view on getting into a STATE FUNDED university: it doesn’t matter what you learn, as long as you learn something.
I’ll stop with that soapbox now before I become even more snarky.
The second article that caught my eye was an editorial in the New York Times promoting the teaching of evolution in schools. The author lays out several great reasons why teaching and learning about evolution is important. In the process, she uses several examples of evolution in action to make her points. Unfortunately, I have to be the nit-picky scientists and point out that many of those examples are not necessarily evolution, but rather adaptations. Still, the ideas in the essay are solid. Many thanks to both the author and the New York Times for defending the teaching of evolution in schools by publishing the piece.
Finally, this all brought me to consider an interview with the US President on NBC I saw the other night. During the interview, Bob Costas did a pretty good job of asking hard-hitting questions, and Mr. Bush talked fairly openly about his visit to China. Three answers stood out to me, and I thought them especially telling of the President’s mind-set as he ends his tenure:
“…I think you should look at the relationship as one of constructive engagement, where you can find common areas like North Korea and Iran. But also be in a position where they can respect you enough to listen to your views on religious freedom and political liberty.”
Why just religious freedom? Why not personal freedom?
“…if you are a religious person you understand that once religion takes hold in a society it can’t be stopped.”
Uhhh… what? Excuse me, did he just say what I think he did? Sounds a little like zealotry to me.
“I went to church here. And I’m sure the cynics say ‘Well, you know, it was just a state sponsored church.’ On the other hand, and that’s true, it gave me a chance to say to the Chinese people, religion won’t hurt you, you ought to welcome religious people. And it gave me a chance to say to the Chinese government, ‘Why don’t you register the underground churches and give them a chance to flourish?’ And he listened politely. I can’t read his mind, but I do know that every time I met with him, I pressed the point.”
Right. So, he disrespected the beliefs of the Chinese President and the ruling party in order to promote his own religious views while acting as the President and official representative of the United States, which officially doesn’t promote religion what with the separation of church and state and all that silly stuff. And, he did it over and over again.
Thank you, Mr. President, for your efforts.

I know that this has already been Boing-Boinged, but I just have to help propagate such awesomeness as the following rap about the LHC by a science writer otherwise known as AlpineKat. Yo’, check it…
Filed under Uncategorized | Comment (0)Climatia in Nature
It’s true. Climatia, the word coined by TWiS’ own Justin Jackson, has been used by one of the most prestigious science journals in the world. Sure, it’s in the art accompanying an article, and it’s not really being used properly in the art, but it’s in there. Climatia has hit the big time.
We interviewed one of the authors, Gavin Schmidt, a year ago in the spring. So, it is possible that he was inoculated with the word at that time. I just have to wonder whether the artist, Mark Roberts, listens to TWiS. I’m guessing that he might.
