4:12 PM | The carbon revolution
Guest post by Rowena Fletcher-Wood If necessity is the mother of invention, discovery is more than fuelled by fashion. After the 1985 groundbreaking discovery of the buckminsterfullerene, the ground for stable carbon allotropes with interesting shapes and properties was just that – broken. In 1990, Richard Smalley postulated the existence of carbon nanotubes as long, extended [...]

12:31 PM | Microfluidic diamond sensor
Greater magnetic sensitivity is also useful in many scientific areas, such as the identification of biomolecules such as DNA or viruses. This research must often take place in a warm, wet environment, where clean conditions or low temperatures are not possible. Scientists address this concern by developing a diamond sensor that operates in a fluid environment.

February 18 is National Battery Day. In honor of this day we’re offering an excerpt from a magazine piece about an ancestor of the modern battery, the Leyden jar.At its simplest the Leyden jar is a glass bottle that is partly filled with water with a wire running into it (later jars had metal foil wrapped around the inside and outside of the glass and no water). Musschenbroek [the inventor] recorded what happened when he first touched the wire after charging the jar: “Suddenly I […]

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.…
