Structured-Illumination Microscopy

Tags: Biology, Science, Technology

A stunning new technology out of UCSF and recently published in Science is producing some of the most amazing 3-D images of living cells. “We threw the conventional microscope out the window and began again,” says John Sedat, a professor of biochemistry and biophysics at the University of California, San Francisco.

Science Meets Art in Paper Horse Kit

Tags: Art, Design, Engineering, Robotics, Science

Art and science complement each other very nicely in this incredibly cool and simple paper kit to build an articulated horse by James Watt from Clockwork Robotics.  (Any relation to the Steam Engine linkage inventor James Watt?) It may not look all that interesting in the static photo above, but check out this video of the model in motion!

We Are What We Drink

Tags: chemistry, Science

Cerling and Ehleringer over at the University of Utah just published a paper in the online journal "Proceedings of the National Academy of Sciences" describing their new forensic technique, which uses Hydrogen and Oxygen isotope concentrations from local water tables in your hair to determine where you have spend your time.The two maps here show predicted average hydrogen (top) and oxygen (bottom) isotope levels in human hair across the continental United States -- isotopes that vary with geography because of different isotope levels in local drinking water. The ratios of heavy, rare hydrogen-2 to lighter, common hydrogen -1 are highest in red and orange areas in the top map, and lowest in the blue and darker green areas. The ratios of heavy, rare oxygen-18 to lighter, common oxygen-16 are highest in red and orange areas of the bottom map, and lowest in the blue and darker green areas.

But, Cerling adds, “You may not be able to distinguish between Chicago and Kansas City.”So in case you're considering a life of crime, you might want toConsider a new bald or buzz-cut look so the ...

Flagging Economy Needs Science Investments

Tags: Education, Science

A very topical Op-Ed piece from Sunday's San Francisco Chronicle by Intel Chairman Craig Barrett. I liked it so much I include it in its entirety here.Flagging Economy Needs Science Investments Craig Barrett Sunday, January 20, 2008"Two years ago, the National Academies published the seminal study on U.S. competitiveness entitled "Rising Above the Gathering Storm." The study identified major shortcomings in U.S. investments in basic scientific research as well as in math and science education for our youngsters. The suggestions contained in this study were immediately picked up by the Democratic House Leadership as their competitiveness strategy and later by President Bush in his State of the Union message under his American Competitiveness Initiative. Legislation in the form ...

Nikon Small World Image Contest Results: 2007

Tags: Photography, Science

Nikon just posted the results from their annual photo micro-graph competition, and the winning images are simply stunning. One of the things that struck me about this year's images was the significant leap in imaging technologies based on florescent DNA tagging combined with the use of confocal microscopy and volumetric tomography, even over last year's images.I really enjoyed browsing the Nikon site, going back in time, to see how science has advanced over even a couple of years. Clearer vision brings clearer insight, as they say; these images let us see things never seen before and witness processes first-hand that were mere hypothesis last year. More than insight, there is wondrous beauty and complexity in every image. Here are a few of my favorites from the 2007 gallery, but don't miss browsing the rest on the home site.Zebrafish embryo midbrain and diencephalon showing neural fibers in blue and developing neural interconnections in red, by Michael Hendricks of the Temasek Life Sciences Laboratory, National University of Singapore.Erpobdella octoculata (fresh water leech) muscle strands surrounding a central nerve cord at 25x magnification, by Vera Hunnekuhl, Department of Zoology, University of Osnabrück, Osnabrück, GermanyGiant unilamellar and multilamellar ...

Science and the Islamic World

Tags: Science

I just stumbled upon a fascinating article on Science in the Islamic World, by a Pakistani scholar named Pervez Amirala Hoodbhoy at PhysicsToday.org. The article is mostly an exploration of the rise and fall of scientific inquiry in the Islamic states and the attendant root causes. There are clearly lessons here even for Western states that face rising tides of fundamentalism and calls for conformity, religious or otherwise.The author doesn't skip a beat as he calls out the similar US trends surrounding religious conservatives and their push for Creationism, Intelligent Design, curbs on genetic research, and so on.But there are also some interesting tidbits on the technologies for daily living in the Islamic world, and how they have penetrated largely in support of the religions which otherwise strive to limit their spread."...while driving in Islamabad, it would occasion no surprise if you were to receive an urgent SMS (short message service) requesting immediate prayers for helping Pakistan's cricket team win a match. Popular new Islamic cell-phone models now provide the exact GPS-based direction for Muslims to face while praying, certified translations of the Qur'an, and step-by-step instructions for performing the pilgrimages of Haj ...

How Nerds Eat

Tags: Humor, Science

I just stumbled on a great post from Julieanne over at Cosmic Variance."My temporary officemate runs down to the vending machine and buys a bag of gummi bears. He dumps them on the desk, sorts them by color, and then proceeds to eat them in order of increasing bin size (i.e. the pile of 1 orange one, then the pile of 3 yellow ones, then the pile of 4 green ones, etc). If I buy a bag of M&M’s, I sort them by color, then figure out a division that lets me arrange them in a triangle, with one color per horizontal row, but allowing colors to be repeated (i.e. it’s ok for 9 red M&M’s to show up as a row of 7, and then further up, a row of 2). I then eat off each diagonal, producing a progressively smaller triangle, but one that maintains the horizontal color structure till the tasty end. My kids, who I suspect inherited a geek-streak a mile wide, also sort multicolored candy into patterns and make up an algorithm for eating it. The non-scientists who I have asked about this habit look at me like I’m nuts. (So do people who ...

Make a Jet Engine in an Hour

Tags: Education, Science

As most of you loyal readers are aware, one of my ongoing crusades is to transform k-12 science education from boring rote cookbook style exercises in contrived tedium into the interesting explorations they SHOULD be.So I constantly have science teachers asking me, "...but what sort of experiments should I have the kids do, and how much would the materials cost? Those Pasco kits are just so convenient."Yes, the pre-fab shrink-wrapped curriculum materials make it easy on the overloaded teacher, but there ensues no opportunity for student innovation or creativity. An example, you ask?Well here is an example for any class discussing fuel, or energy, or Newton's laws of action and reaction. And it involves fire, which tends to keenly engage the teenage mind.Have your middle or high school science students make jet engines and test them.Sounds dangerous? That's what protective glasses and gloves are for.Sounds expensive? Try almost free with a recycled jar.Sounds out of reach of most secondary students? Pah! Let them try and they will surprise you.Make Magazine has a great podcast and written directions on how to make a Pulse-jet engine out of a used jam jar. The ...
