Brazil elected the new president in a violent climate: Lula won the elections with a 0.9% margin

More than 156 million Brazilians - those eligible to vote - were called to elect the new president Sunday, October 30. These elections, which saw two candidates - Lula and Bolsonaro - radically opposite in almost every aspect of their politics, were characterized by an extreme climate of violence. Recent events include shootings in public places, the murder of a politician, and even explosives thrown at the crowd of a political rally. Due to the tense climate, the two candidates have been seen constantly escorted by security or police, even wearing bulletproof vests. Pre-election polls suggested Lula was slightly favorite to come back for a third term, capping a remarkable political renaissance after his jailing on graft convictions that were overturned. But Bolsonaro is known as a hard-to-beat politician, very well capable of upturning polls predictions with promises through electoral campaigns - in his last days of the campaign he promised, for instance, a raise of the minimum wage to $260. Besides electoral promises, Bolsonaro was involved in more than one questionable episode. On Sunday, one of Bolsonaro's allies opened fire on Federal Police officers coming to arrest him. A week earlier Bolsonaro had to defend himself from personal attacks after he told an anecdote about meeting Venezuelan migrant girls in suggestive terms. During the last debate on Friday night, both candidates returned repeatedly to Lula's two terms as president from 2003 to 2010, when high commodity prices helped to boost the economy and combat poverty. Lula vowed to revive those boom times, while Bolsonaro suggested current social programs are more effective. In such a controversial climate the Brazilians were called to vote and made their choice: for the next four years, Lula is the elected president of Brasil, as he won by obtaining 50.9% of the total valid votes. Since the current president Bolsonaro made clear that he would not easily accept a defeat, many observers are worried that a peaceful transition of power may not take place. Indeed, during vote counting, Bolsonaro has cast unsubstantiated doubts on the trustworthiness of Brazil's electronic voting system this cycle. At the same Lula da Silva, allies accused the police of blocking buses and cars carrying Lula voters from getting to voting sites. However, the Superior Electoral Court, which runs Brazil's elections, said no one had been prevented from voting and declined to extend the voting time. In these hours leaders from around the world are sending Lula congratulations and best wishes for the difficult mandate he just obtained.

The habit of nose-picking is common in primates and the cause may be evolutionary

Nose-picking is a common behavior in humans, often avoided in public since generally considered rude, “low class”, or even repugnant. Probably for the same reason, it is a behavior that remains poorly understood and studied even in animals. But not for the zoologist Anne-Claire Fabre of the University of Bern, who recently published a paper in the Journal of Zoology reporting noise picking in the lemur species aye-aye. In the same article, she also reviews the presence of this habit in various primate species, showing that it is present in at least 12 species. In the aye-aye lemur - whose characteristic is an extremely long, skinny, and mobile middle finger - accurate imaging shows that the insertion depth during the gesture reaches the pharynx. Since so many primates - many humans included - would utilize their fingers to collect and ingest nasal mucus, the scientists suspect that the behavior may have evolved for selective reasons such as, for instance, a sanitary or even a medical advantage. More studies will be needed to demonstrate any of such advantages. However, nose-picking is possible only in those species - like primates - that have fine manipulative skills, and therefore are sufficiently evolved. Some primates even use utensils to collect mucus from the nose. Once more, nature offers an unparalleled source of information, crucial to understand even those behaviors that pass unseen in our quotidian life. Biodiversity is the only mirror we have for transcending the social paradigms, observing the animal features that we all share, and understanding their importance.
