7:23 PM | 'Medicina sin engaños' de J.M. Mulet [Reseña]
¿Sabes como llaman a la medicina alternativa cuando se prueba que funciona? El británico Tim Minchin se hacía esta pregunta en su archiconocido Storm, una divertida canción/poema de este excéntrico genio del humor que compartí por aquí hace ya la friolera de casi tres años. Tendrás que ver el monólogo para saber la respuesta a la pregunta. O leer el último libro de Mulet. Te recomiendo las dos cosas, pero […]

5:47 PM | This is Why There are So Many Defibrillators in Casinos
By: Jordan Gaines Lewis, 4th year PhD candidate in the Neuroscience Graduate Program My brief experience in a casino was pretty typical, I’d say. Flashing lights. The faint smell of booze. Not much chatter among patrons. The sounds of dice rolling, machines buzzing, and coins clanking. The same butts inhabiting the same stools for hours on end.…

4:40 PM | What's going on at Pixar?
A respected reader noted this article at Wired which measured the vaccine rates of parents who leave their children at Silicon Valley region company-run day care centers.I tend to think this is a proxy for some other socioeconomic indicator, but I dunno. Thoughts?

9:17 AM | Non-destructive subsurface imaging of carbon nanotubes in polymer composites
Researchers report a non-destructive and high throughput 3D imaging of carbon nanotubes (CNTs) embedded in polymer matrix via Scanning Electron Microscopy (SEM). While have been several open questions remaining for SEM subsurface imaging of CNTs, this new findings clarify these issues and help establish SEM subsurface imaging as a useful and facile method to provide quantitative 3D information on CNT dispersions in polymer composites.

9:06 AM | How to make silver nanowires almost indestructible
Researchers found that silver nanowires can be made almost indestructible and highly bendable by covering the minuscule wire with silicon dioxide. The new material can be used for making next generation optical cables, which until now have been easily fractured if bent. The new material 'memorizes' its original position and regenerates when needed.

7:26 AM | Discovery of a factor that determines the photocatalytic activity of titanium dioxide
Researchers have discovered through the in situ observation of the behavior of photoexcited carriers on the surface of a titanium dioxide crystal used as a photocatalyst that the carrier (electron and positive hole) lifetime on the crystal surface is an important factor to determine the catalytic activity.

9:01 PM | Vanille et vanilline
Les Manchettes scientifiques d’Ariel Fenster Tout d'abord je dois vous expliquer l'absence de manchette la semaine dernière. J'ai été invité à donner une conférence sur la «chimie du chocolat» à l'Université de Floride à Jacksonville. Avoir l'occasion d'aller en Floride au mois de février… je ne me suis pas […]

7:39 PM | A note/request on the "I Quit Graduate School in Chemistry" from Prof. Tehshik Yoon
An e-mail from someone I respect, Professor Tehshik Yoon, on this project: CJ and I exchanged a couple tweets of the other day, in which I expressed a bit of ambivalence about his #IQuitGradSchool project. Tweets, of course, are a terrible way to capture complicated feelings, so CJ reached out and offered me the opportunity to explain what I meant in a guest entry on his blog. So first of all, let me say that I essentially like the project.  What I like most about it is the same […]

Whether you’re a coffee connoisseur or completely unfussy about the manner in which you get your caffeine fix, there’s no denying that the smell of freshly-brewed coffee in the morning is an invigorating one. The chemistry behind this aroma, though, is far from simple; a complex collection of chemical compounds are responsible, and this graphic takes […]

5:26 PM | Trian vs. DuPont - Round 3
Nelson Peltz and his Trian Partners Group is still dogging DuPont. Having lost the last round (when DuPont explicitly told him that no, he cannot be on the board of directors and that DuPont was going instead add 2 more of directors of their own choosing), Peltz is still hoping a proxy fight will get him the directorship he so craves. And just like what Daniel Loeb did when he was attacking Dow, Peltz now has his own website, dupontcanbegreat.com [*]. His nominees for 3 other director chairs […]
