International School of Advanced Studies (SISSA) A simulation to observe how hydrogen behaves at very high pressures Some experiments are really difficult to perform in practice. To gain a detailed understanding of the behavior of molecular hydrogen (H2), for example, we would have to produce such high pressures as those occurring within the core of gaseous planets like Jupiter and Saturn or inside stars. If such conditions cannot be created, an alternative method is to simulate them on...

In Moral Behavior, 'Virtual' Reality Is Something Else Altogether
2014-01-16 10:06:27

International School of Advanced Studies (SISSA) The brakes of your car fail suddenly and on your path are five people who will certainly be hit and killed. You can steer, but if you do another pedestrian will find himself on your course. Just one. What do you do: do you take action and kill one person or do you do nothing and cause five people to die? This is an example of a "moral dilemma", the type of problem cognitive psychologists use for studying the cerebral foundations of moral...

Scientists Explore Mechanisms Of Viruses' Shells
2013-12-11 09:41:20

International School of Advanced Studies (SISSA) Viruses are like small vessels containing an active component, the genetic material, that can infect a host cell. The vessel, called capsid or vector, is basically a shell that changes its shape when it penetrates a cell to infect it, and may even break into pieces. The research team, that includes Guido Polles and Cristian Micheletti of SISSA, carried out computer simulations and used theoretical models to understand how such 'vessel'...

Reading Into The Brain To Understand How Neurons Represent The World
2013-04-23 15:33:22

International School of Advanced Studies (SISSA) We know the world through the sensory representations within our brain. Such "reconstruction" is performed through the electrical activation of neural cells, the code that contains the information that is constantly processed by the brain. If we wish to understand what are the rules followed by the representation of the world inside the brain we have to comprehend how electrical activation is linked to the sensory experience. For this...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
