Columbia scientists have identified a brain region that helps tell an animal when to attack an intruder and when to accept it into its home. This brain area, called CA2, is part of the hippocampus, a larger brain structure known to be critical for our memory of people, places, things and events. CA2 was already…

And at no point do we ever stop to wander. That what can so easily change. Cannot truly exist after all… In…

Measuring the cosmos… Ghosts and numbers…
A groundbreaking experiment in physics has for the first time provided a precise measurement of a force between electrons and protons called the weak nuclear force. The value 0.0719 (give or take 0.0045) won't mean much to most of us, but the way they did it makes way for some exciting possibilities for pushing physics…

Counting till the end… Numbers… Infinite… Water and fire…
Gisin, of the University of Geneva, debates the physical reality of real numbers. His main problem lies with real numbers that consist of a never-ending string of digits with no discernable pattern and that can’t be calculated by a computer. Such numbers (like π for example) contain an infinite amount of information: You could imagine…
