A statistical analysis of the effects of very hot nights on the death rate in Barcelona’s environment reveals that, during these nocturnal periods, more deaths occur due to natural, respiratory and cardiovascular causes. Although this year would seem to break the trend, the number of ‘tropical’ nights has increased in the Catalan capital over the last few decades.
Football enthusiasts suspected it, but now statistics is confirming it. After analysing all the matches of the Spanish league “La Liga” from the 2014-2015 season, two experts in sports science have found that the greater the difference on the scoreboard, the less stoppage time is added to the end of the game. When the score is tighter, however, referees tend to add more stoppage time when the team in the higher division is losing.
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.
Researchers at Pompeu Fabra University (Spain) have created a high resolution atlas of the heart with 3D images taken from 138 people. The study demonstrates that an average image of an organ along with its variations can be obtained for the purposes of comparing individual cases and differentiating healthy forms from pathologies.
