Recreational drug use is related to impulsive behavior, Spanish resear
Psychologists in Spain have just concluded a study regarding the use of addictive substances by young university students and the manifestation of impulsive behavior in the same group of people, on a cognitive and psychomotor level. The findings suggest that regular consumers of cannabis and alcohol are more impulsive than non-users.

A new analysis shows that it a lot prettier (mathematically speaking) if you're moving at just the right speed, leading to an improvement in calculations describing colliding particle beams and lasers by factors of a million or so. Cells Take Risks With Their Identities
Contrary to textbook models, many genes that should be "off"in embryonic stem cells and specialized adult cells remain primed to produce master regulatory proteins, leaving those cells vulnerable to identity changes. The genes encoding the master regulators of cell fate begin making RNA templates for these proteins, though a control mechanism stops them from finishing the job.
