 Egg-beater centrifuge may save lives

$2 Egg-beater centrifuge may save lives

Harvard’s George M. Whitesides is arguably the world’s most significant chemist. How arguably? Whitesides has the highest Hirsch index of any living chemist in the world. The Hirsch or h-index is a kind of weighted score based on a numerical analysis of a scientist’s published work which factors in both the number of papers and the number of citations those papers receive by other authors.

Back in October of 2008, Whitesides published a paper in the Royal Society of Chemistry’s journal Lab on a Chip that describes a technique for separating blood plasma for use in various immunoassays using a piece of plastic tubing taped to an eggbeater. The method can replace a $400 bench centrifuge for many purposes.

How-To:  Cure colorblindness in an adult primate

How-To: Cure colorblindness in an adult primate

OK, OK, this is probably something you shouldn’t try on yourself, a loved one, or even a close friend. Still, it’s pretty flippin’ amazing: a full-grown animal, permanently (apparently) cured of a genetic defect by a few injections. Can X-people be that far behind?

(That’s a rhetorical question, BTW; those of you who know the real answer to that question is “yes,” just chill and give me my moment.)

Here is the original abstract at Nature.

Open-source 3D DNA origami

Open-source 3D DNA origami

So. Incredibly. Cool. What is DNA Origami? DNA origami is a powerful method for constructing DNA objects. It involves taking a long, single-stranded DNA backbone (usually about 7000 bases in length) and forcing it to adopt an arbitrary shape using hundreds of short, single-stranded DNA oligonucleotides (each usually 20 to 50 bases long). This method […]

Persimmon wine: patience pays

Persimmon wine: patience pays

bbum’s posted the results of his latest project. It looks very tasty: The sweet essence of persimmon is both present in the nose and in the flavor. And the characteristic astringency of persimmon carries through, too, giving the wine a slight “pucker” at the end… And this was an exercise in patience. Despite an iffy […]
