Spanish researchers have developed a system that tracks human displacement caused by climate change using the tracks of mobile phones. With this model, which was tested during a severe drought in Colombia in 2014, it was determined that the portion of the population that migrated due to this event was 10% during the six months of the study.
When ants go exploring in search of food they end up choosing collective routes that fit statistical distributions of probability. This has been demonstrated by a team of mathematicians after analysing the trails of a species of Argentine ant. Studies like this could be applied to coordinate the movement of micro-robots in cleaning contaminated areas for example.
The learning mechanism of neurones has inspired researchers at the University of Valladolid (Spain) to create algorithms that can predict whether a bank will go bust. The model was correct for 96% of the banks that went bust in the USA in 2013 after analysing their financial indicators from the previous decade, marked by the economic crisis. The most vulnerable were those which had accumulated loans from the construction sector and grown rapidly without sufficient provisions.
When we must choose between cooperating with others or betraying them, we are more likely to cooperate if they have acted like this with us or if we ourselves have behaved altruistically. We do so because learning reinforces what has gone well for us and not because we imitate successful people. These are the conclusions highlighted in a study conducted by the Carlos III University of Madrid based on the prisoner’s dilemma, a popular model for studying conflict.
Researchers at the University of Cordoba (Spain) have developed a system that measures compatibility between donors and the most serious receivers in liver transplants. This is a mathematical method that includes the experience of almost 1,500 donations registered in transplant units in Spain and the United Kingdom.
