“Black Panther” finds no rival in its third week in the US
The phenomenon of “Black Panther”, the Marvel film with a cast almost entirely made up of black actors, continued to shine in its third week in theaters in the United States, where it easily won the premieres of “Red Sparrow” and “Death Wish”.
According to the data from the specialized portal Box Office Mojo, “Black Panther” this weekend added 65.7 million dollars, which led to reach 501 million in the United States alone and to be the tenth highest grossing film in history in the North American market.
Around the world, the film has raised 897.7 million so far.
In the film by Ryan Coogler, praised for his diversity in front of and behind the camera, T’Challa (Chadwick Boseman), after the death of his father, the king of the fictional Wakanda, returns to his home, an African nation isolated from the world but with tremendous technological potential.
Until the second place climbed the thriller of espionage “Red Sparrow”, that in its disembarkation in the American cinemas it entered 17 million.
Jennifer Lawrence plays a young woman recruited against her will by a program of Russian espionage, which instructs her to become a lethal secret agent.
With the bronze medal the action film “Death Wish” was formed, which in its first weekend on the big screen scored 13 million.
Bruce Willis gets into the skin of a man who, after his wife is murdered, he takes justice by his hand and travels the city to find the perpetrators of the crime.
In fourth place was the action comedy “Game Night”, which added 10.7 million.
The film, starring Jason Bateman and Rachel McAdams, tells how a group of friends who meet often to have fun with board games is involved in a criminal investigation.
Finally, the animated feature “Peter Rabbit” got 10 million.
This adaptation of the classic story by Beatrix Potter, about a rebellious rabbit trying to enter a farmer’s garden, has the voices of James Corden, Domhnall Gleeson, and Sia in its original version.

Anti-fascist groups demonstrate in Macerata after attack on immigrants
Anti-fascist groups demonstrated on Saturday in the Italian city of Macerata, where an ultra-right-wing fired six African immigrants in an initiative supported by the new progressive party Free and Equals.
The fact that Macerata turned immigration and racism into the center of the election campaign debate.
The demonstration was not authorized by the Interior Ministry until last night when organizers assured it would be totally peaceful.
However, the town council of this small town of 41 thousand inhabitants ordered to close all the stores and to suspend the classes in the institutes (Saturday is a day in Italy), before possible incidents between the antifascists and the ultra-right ones.
On Thursday, 100 sympathizers of the neo-fascist Forza Nuova formation demonstrated through the streets of Macerata, although the demonstration was banned, to support the “revenge” of one of its candidates, Luca Traini, against the immigrants.
Traini fired on immigrants for “revenge” after the murder of 18-year-old Pamela Mastropietro, allegedly murdered by a Nigerian drug dealer.
On this occasion, the group carried out clashes with the police when trying to have access to the center of the city and there were at least six people injured and a dozen were detained.
At today’s demonstration, which was expected to attend about 5,000 people, joined anti-fascist groups, unions and humanitarian organizations such as Emergency.
Faced with the heavy atmosphere in Macerata, the Democratic Party (PD) of Matteo Renzi chose not to participate.
The mayor of Macerata, Romano Carancini, explained that he will not be present because “the city was not prepared for this” and that “it was not necessary to manifest a few days of this tragedy”, but assured that “it will be with the heart along with all democratic forces that will march, “in an interview with the newspaper Fatto Quotidiano.

The greater the number of bee species, the better pollination
Bees have a key role in both the ecosystem and the human being’s diet. Along with bats and some birds, these insects, of which there are more than 20,000 species, carry out the pollination of flowering plants, which include fruits and vegetables. Thus, they affect about 35% of world agricultural production, according to the United Nations Organization for Food and Agriculture (FAO, for its acronym in English).
However, until now, research has underestimated the number of bee species necessary for correct pollination in fruit and vegetable crops. To ensure a sufficient transfer of pollen, bee colonies of honey (Apis Mellifera) are used.
A study, published in the journal Science, now reveals that the pollination activity performed by this species is not sufficient for this task, but needs the joint action of wild bees to maximize production.
The work, led by Rachael Winfree, of the University of Rutgers (USA) with the participation of the Biological Station of Doñana (EBD-CSIC), has accounted for the species of bees necessary to pollinate the crops of watermelon, blueberries, and redcurrants in 48 agricultural estates of the mid-Atlantic region of the United States.
To understand the impact of bee diversity on large-scale pollen transfer, the researchers measured the amount of these microscopic grains that each species provides in a single visit. The results highlight that of the 100 species that found more than 50 were indispensable to ensure the correct pollination of the farms.
“If we want to maintain the pollination of the fruits and vegetables we eat, we need to conserve many more species of bees than we thought,” explains Sinc Ignasi Bartomeus, CSIC researcher at the Doñana Biological Station.
“This happens because, in a given farm, you can ensure the correct pollination of the crop with few species. However, in another farm, that role will be different types of bee. Thus, in an entire landscape, the number of species needed increases substantially, “concludes the researcher.
So far, numerous studies have investigated the influence of biodiversity on ecosystem functions such as biomass production, nutrient cycling or pollination. However, it is debated whether the findings of field and laboratory experiments can really be applied to natural systems.
According to the researchers, these types of experiments are not enough to understand how biodiversity affects ecosystem functions since they do not cover essential factors and circumstances that are vital in nature.
In the first place, there is a great difference in the studied surface: while the experiments analyze areas of about 3 m2, the natural spaces extend over thousands of km2. This means ignoring factors such as the distribution of species and other spatial patterns that influence the ecosystem.
On the other hand, when conducting experiments, conditions related to the structure of the community are controlled, as well as the variety of species. However, in the wild communities not only biodiversity varies, but also the composition, dominance, and abundance of each population.
“The experiments have the advantage that you can control all the variables that do not interest you and focus on just one, in this case, the richness of the species. But there are factors that can not be detected in experiments, “explains Bartomeus, for whom it is essential to study on a real scale the effects of diversity on food production.
The study shows that at smaller spatial scales, achieving 50% pollination requires 5.5 species of bees. However, reaching the same threshold in the 48 farms requires 55. This shows that places with low levels of pollination will require more or even all the bee species, including the strangest ones, to reach a sufficient level.
“This is very good news because it implies that the conservation of biodiversity and agricultural production must go hand in hand and that sustainable cycles can be generated where we all win,” concludes the expert.
