11:00 AM | 3-D Proteins...
Image Source: Technology ReviewTopics: 3-D Objects, Algorithm, Biology, Computer Science, Molecular BiologyTECHNOLOGY REVIEW: One of the great challenges in molecular biology is to determine the three-dimensional structure of large biomolecules such as proteins. But this is a famously difficult and time-consuming task.The standard technique is x-ray crystallography, which involves analyzing the x-ray diffraction pattern from a crystal of the molecule under investigation. That works well for […]

7:40 AM | Thou Shalt Worship No False Lagrangians
I’m usually quite restrained with this blog – I try to keep it mostly to facts about cool physics/maths interspersed with more personal bits and pieces about life as a PhD student. This post, though, might provoke strong opinions, and I’ve rewritten it quite a few times already. In fact, this current draft was originally […]

4:00 AM | Le forze che muovono le stelle
Si tratta di una scoperta che sta cambiando la nostra visione sul modo con cui la fusione (merging) di due galassie può determinare un insolito moto stellare nelle galassie ellittiche risultanti: i dati suggeriscono che la regione centrale ruota nella direzione opposta a quella delle altre stelle della galassia. I risultati di questo studio sono pubblicati … Continue reading Le forze che muovono le stelle →

4:03 PM | Simpler nanoscale bioreplication of beetle decoys
Ash trees in 22 eastern states of U.S.A. are being decimated by emerald ash borers (EABs), an Asian beetle that arrived in Michigan more than two decades ago. The pest has even spread westwards into Kansas and Colorado. Nothing seemed to be effective against EABs, until decoys designed to mimic female EABs were found in 2012 by a group of researchers to be successful in enticing male EABs for mating. Last year, the same researchers found the decoys could be used to electrocute and kill the […]
