Fighting Zika: Medicinal plant discovered in North East of Brazil

RIO DE JANEIRO (Brazil)- Brazilian researchers discovered a plant in the North East of the country that could be used to fight against the mosquito (Aedes aegypti) which transmits the viruses of Zika, dengue and chikungunya.

The discovery was made by biology students of the State University of Piaui. The study, which started in 2013, was intended to show the effectiveness of “pinon rojo” to eliminate mosquito larvae.

During the study, various levels of larvae of Aedes aegypti were put on the plant. However, when the mosquitoes at larva stage were put in contact with the substance, they died two or three days later because of a toxin secreted by the plant, said the researches on Monday.

According to the researches, the study showed that the pinon rojo succeeded in killing the larvae with a level identical to that of the chemical insecticide.

The mosquito (Aedes aegypti) which causes the Zika epidemic spreads across Southern America, and is now widespread in Brazil.

COP 21: 195 countries adopt Paris climate agreement

LE BOURGET- The representatives of 195 countries adopted in Paris a global agreement to fight against global warming, the source of climatic changes and increasing threats to humans and nature.

After thirteen days of painstaking negotiations and talks, the countries gathered in le Bourget succeeded to reach a compromise agreement that brings together the positions of the various protagonists.

“I look at the room, I see that the reaction is positive, I did not hear any objection, (then) the Paris climate agreement is adopted,” said the president of COP21, Laurent Fabius, sparking a standing ovation of several minutes, hugs, shouts of joy, throughout the room.

Considered as a milestone for limiting global warming, the Paris agreement, dubbed “historic”, after the failure in 2009 at Copenhagen, was approved the member countries of the UN Framework Convention On climate, in plenary session, which was attended by Minister of State-ALGERIA, Minister of Foreign Affairs and international Cooperation , Ramtane Lamamra.

The “just”, “sustainable” and “binding” agreement has not been put to vote since the consensus already exists in the United Nations Framework Convention on Climate Change.

It must be ratified by the parliaments of the Contracting Parties.

The agreement insists “strongly” on “urgent need to bridge the significant gap “between the overall effect of the mitigation commitments of Parties in terms of the annual global emissions of greenhouse gases until 2020 and counter the increase of the Planet’s average temperature below 2°C.
