Molecular simulations are a powerful tool and they have provided predictions in a wide variety of physical and chemical systems that have later been verified by experiments. They can even be used to study how experimental probes disturb physical systems and in some cases they can be used to design molecules with desired physical properties.
The correctness of simulation protocol is crucial for obtaining physically correct and predictive results. If not chosen carefully, one can obtain quite spectacular but physically incorrect results. In the reference below [1], we demonstrate that there are critical several issues that need special attention especially in carbon nanotube systems. In particular, the treatment of charges is of extreme importance. In addition, thermostatting in Molecular Dynamics simulations may create additional problems. In addition to carbon nanotubes, our results also apply to biological systems such as aquaporin and other passive channels.
This movies shows water molecules entering a carbon nanotube. Hydrogen bonds are shown in yellow (notice how they form and break). See also the movie of a carbon nanotube connecting water reservoirs: nanotube model for aquaporin
Simulations were done with Gromacs.

The free Stellarium planetarium software (stellarium.org) now supports plugins and includes one called "Satellites" that adds display of artificial satellites to the standard sky objects. This view shows the ISS in a pass that I saw from my front porch earlier tonight.

A movie showing a snapshot from a Molecular Dynamics simulation of ethanol (the usual drinking alcohol; methanol, on the other hand is poisonous) interacting with (POPC) lipids. This movie showing how ethanol (blue and red) has hydrogen bonded with (POPC) lipids.
Details: the simulation is in explicit (SPC) water (removed from visualization for clarity). 90 ethanol molecules. Lipids (128 in total): POPC. Gromacs simulation engine.

College of DuPage health Sciences students participated in a multi-discipline simulation involving students currently in the College's EMT, Nursing, CT, Surgical Tech, Nuclear Medicine and Respiratory Care programs. The scenario, played out by a combination of actors and mannequins involved a domestic situation in which a husband shot his wife and two children leaped from a two-story window to avoid a fire.

Hair Simulation : Letter A
Playing with hair simulations, these a little more abstract than the others.
Dans le cadre de la Semaine nationale de la prévention de la noyade, les sauveteurs de la piscine la Joie ont pris part à une simulation d’un cas de colonne afin de faire de la prévention auprès de la population face aux dangers en piscine. Sous la supervision de la chef-sauveteur Laurie Gardner, l’équipe de sauveteur est intervenue afin d’effectuer un sauvetage simulé d’un baigneur ayant malencontreusement plongé dans la partie peu profonde de la piscine. Après avoir sifflé l’évacuation immédiate de la piscine, les sauveteurs ont travaillé de pair pour effectuer la sortie de l’eau de la victime blessée à la colonne vertébrale.
En cette Semaine nationale de prévention de la noyade, les ambulanciers d’Urgence Bois-Francs et les pompiers du Service de la sécurité publique de Victoriaville ont eux aussi participé à la simulation, et ont pris en charge la victime blessée à la colonne après la sortie de l’eau effectuée par les sauveteurs. Une communication efficace et le calme de tous ont contribué à faire de cet exercice de sauvetage un réel succès.
À la suite de cette simulation, des ateliers d’éducation au public ont été organisés avec la collaboration de Victoriaville en santé, et ce, tout au long de l’après-midi. Les personnes intéressées à connaitre quelques techniques de sauvetage et de réanimation cardiorespiratoire (RCR) ont pu se rendre sur place lors de cette journée de prévention.
La prochaine activité d’éducation au public portant sur les ateliers de sauvetage et de RCR est prévue le jeudi 31 juillet à 14 h à la piscine des Forges située sur la rue de l’Académie.
