It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes that would occur if one could travel back in time. For example, would it be possible to travel back in time to kill one’s grandfather? In the Grandfather paradox, a time traveler faces the problem that if he kills his grandfather back in time, then he himself is never born, and consequently is unable to travel through time to........

“One of the fundamental questions of evolutionary biology is how vertebrates with all the same genes display such vastly different characteristics. The Burmese python is a great way to study that because it is so extreme,” Castoe, who began working on the python project as a postdoctoral fellow at the University of Colorado School of Medicine in the laboratory of associate professor and paper corresponding author David D. Pollock.
Castoe said: “We’d like to know how th........ Read more »

Implantable slimming aid
ETH-Zurich biotechnologists have constructed a genetic regulatory circuit from human components that monitors blood-fat levels. In response to excessive levels, it produces a messenger substance that signalises satiety to the body. Tests on obese mice reveal that this helps them to lose weight.___ ETH Zurich

To be a Spartan: Spartan psychology and living
parts I & II
Nowadays, most military experts consider the Spartan hoplites as the first real elite soldiers in World History. This conclusion is not surprising. Almost the only criterion for characterizing a Spartan man as good or no good, depended on his behavior in battle. What should never happen to him, was to lack in battle [...]
