The largest analysis of user behavior on social networks, GlobalWebIndex, has just released its latest report. The study, based on interviews with more than 152,000 people in 31 different markets, suggests that Facebook users are the most active of all social platforms, with 64% of users contributing their activity.
There are many ways to manipulate the results of a vote, and some of them can be detected with statistical tools, as a team of scientists has shown in a work published in the journal PNAS. Researchers have developed a mathematical model that detects two types of fraud. The first case, which they have called 'gradual fraud', occurs when ballots of one candidate are added and those of others are withdrawn.
A team of scientists from Harvard University (USA) has managed to control the behavior of a small transparent earthworm by manipulating the neurons of its tiny brain. The results, which are published in the journal Nature, represent an advance in the understanding of how the brain works.
It has a very strange name, but most of us have played or built one on occasion. The thaumatrope is an optical toy that is used to produce a sensation of movement in images. It consists of a disk with an image on each of its faces. Two strings or rubber bands are placed at the ends of the disc that twist a lot, so that, when stretched, the disc begins to rotate at full speed. The rapid turn creates in the viewer the optical illusion that both images are together.
Biologists at the University of St. Andrews (Scotland) have been inspired by the concept of Twitter, the microblogging service used to publish short text messages known as tweets, to observe what happens when birds come into contact while in Liberty.
On September 19, the robot Curiosity, which landed a little over a month ago on the surface of the red planet, encountered a pyramidal stone on its way. NASA technicians thought it was a good time for the rover to make a stop and put all its analytical instruments to the test.
By combining the best images of galaxies taken in recent years by the Hubble telescope, NASA astronomers have created the deepest image of the universe obtained to date. Specifically, it combines 2,000 different photos taken during two million seconds, and contains 5,500 galaxies
A new study by Canadian scientists has identified a direct relationship between a dog's personality, how long it lives, and how much food it eats. The more obedient races live longer than the disobedient ones. And the most aggressive ones have a higher energy expenditure.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
