Voting is reopened in Nigeria after problems with electronic voting machines

The polling stations opened again in Nigeria on Sunday (29) to continue to vote to choose the country's next president, after the problems recorded on Saturday (28) with the new electronic system of accreditation which forced the postponement.
Besides the problem in the new system, violence has also upset the vote.

Nigeria has presidential elections amid threats of Boko Haram
Extremist Boko Haram, which had promised to disrupt the vote and, in fact, caused its postponement for six weeks, kept their promise: the group is suspected of having carried out bloody attacks, including two polling stations of the country's northeast.
At least 15 people died in the attacks, including an opposition politician.
The postponement "affects about 300 polling stations out of a total of 150,000," said a spokesman for the Independent National Electoral Commission (INEC), Kayode Idowu.
Some of these polling stations opened their doors at 8 am (local, 4pm GMT) to accredit citizens who could not make it this Saturday (28).

With the electronic system of accreditation specifically created for these elections, Nigerians, before voting, must validate their voting cards through an electronic reader that also proves your fingerprint.
Although since early morning on Saturday many Nigerians have been queuing to vote in some centers card readers did not work and delays at the polls were very significant.
In order to prevent new errors in the system today, the Electoral Commission has authorized, if readers continue malfunctioning, the cards of voters are proven manually.
In addition to the technological problems, the election on Saturday came amid a wave of terrorist attacks in several constituencies, which left at least 15 people were killed in the queue.
These presidential elections, which should have happened on February 14, were postponed to try to ensure the security of citizens.

may have found key to have life

The Curiosity vehicle NASA discovered nitrogen on the surface of Mars, mean something that contributes to evidence that the Red Planet could have supported life in the past - said the US space agency said on Tuesday.

When drilling Martian rocks, the rover Curiosity found evidence of nitrates, nitrogen-containing compounds that can be used by living organisms.

The Curiosity team has found evidence that other ingredients necessary for life, such as liquid water and organic matter, already existed in the place known as Gale Crater.

"Find a biochemically accessible form of nitrogen is one more argument for the thesis that the ancient Martian environment in Gale crater would be habitable," said Jennifer Stern's Goddard Space Flight Center of NASA in Greenbelt, Maryland.

Nitrogen is essential to all known forms of life because it is a building block of DNA and RNA.

However, "there is no evidence to suggest that nitrogen molecules found by the team were created for life," warned NASA.

"The surface of Mars is inhospitable for known forms of life," said the agency.

The research team suggested that, instead, nitrates are old and probably came from meteorite impacts, rays and other non-biological processes.

On Earth and Mars, nitrogen is found in the form of nitrogen dioxide gas - two atoms stuck together so tightly that not react easily with other molecules.

The nitrogen atoms must be separated or "fixed" so that they can participate in chemical reactions necessary for life.

"On Earth, some organisms are able to fix atmospheric nitrogen and this process is essential for metabolic activity," said NASA.

"However, smaller amounts of nitrogen are also fixed by energy events like lightning."

The Curiosity vehicle is currently at the foot of Mount Sharp, a mountain 5,500 meters, formed by sedimentary layers.

In December, the robot detected regular methane emissions near the Martian surface, but the origin of the phenomenon is unknown.

Scientists do not expect the rover Curiosity find aliens or life on Mars, but hope to use it to analyze soil and rocks for signs of the key elements for life that the Red Planet may have harbored in the past.

The vehicle of $ 2.5 billion also aims to study the Martian environment to prepare for a possible human mission there in the coming years.

The US president, Barack Obama, promises to send humans to the Red Planet by 2030.

The French health system studies project takes protesa mammary the country

A study by the Cancer Institute of France, released on Tuesday (17), reveals that breast implants can cause a rare type of tumor in the lymphatic system.
Due to the conclusions of experts, the French government is currently studying the prohibition of breast implants in the country.
Researchers from the National Cancer Institute (NCI) of France revealed the existence of a new disease, "anaplastic large cell lymphoma associated with a breast implant (ALCL-AIM)" and proposes that this cancer be included in the classification diseases of the World Health Organization (WHO).
"There is a clearly established link between the emergence of this disease and the use of a breast implant," says the report by the French Institute. "This cancer was not diagnosed in any woman without prostheses in the breasts."
French oncologists estimate that the risk of lymphoma in women with breast implants is 200 times higher than in the general female population.
They point out, however, that the frequency of the medical complication is very low. Since 2011, only 18 women developed this cancer in France (one of them is dead), according to the INC.
Surveillance
The study was conducted at the request of the French authorities of health after the rapid increase of cases of this cancer in a relatively short period.
Although the number of affected people still be very limited, which worries the authorities is the speed of progression: the total number of new cases increased from two in 2012 to 11 last year.
The Health Minister Marisol Touraine said on Tuesday that women with breast implants "do not have to remove them" and should not be "overly concerned".
"Our vigilance is total," the minister said, adding that any breast implant brand is being targeted specifically in relation to the discovery of this new tumor.
Touraine also stated that the information to women wishing to place breast implants will be strengthened.


SHORT THE WELL-BEING

The National Agency of Drug Safety (MSNA) of France has announced that women who wish to put implants in the breasts should be "necessarily alerted about this new venture, even though he is down," he said in an interview with Le Parisien newspaper, François Hébert, deputy director general of the agency.
According to him, information documents and alerts on the issue have been sent to physicians in the country. "If you need to ban the implants, we will," said the director of MSNA.
The French agency will meet with experts later this month to decide on the matter. A possible ban of the prosthesis will depend on the conclusions of the researchers.
"The signs are compelling. The cases increase. We are exchanging information with the FDA (Food and Drugs Administration) American," says Professor Benoit Vallet, Director General of Health, which determines the French public policies in the area.
"Health professionals should be more vigilant against this risk. Women who wear dentures should be examined by a doctor every year."
Scandal
The discovery of new risks involving breast implants is only five years after the scandal of the French brand PIP prostheses, which shocked the country. They were produced with a silicone gel not authorized for medical purposes and fuel containing no additive tested for clinical use.
The PIP was the world's third largest manufacturer of breast implants and exported to many countries, including Brazil. According to the MSNA, about 400,000 women in France have prosthetic breasts, 80% of them for aesthetic reasons.

Cientistas japoneses advertiram para a mudança no padrão de movimento das placas tectônicas do Japão, completamente diferente do que tinham antes do terremoto de 2011, e aconselharam que a população fique alerta perante possíveis sismos similares. Pesquisadores da Autoridade de Informação Geoespacial (GSI), dependente do Ministério de Transporte e Infraestrutura, detalharam que as placas tectônicas do país asiático e de seus arredores estão em contínuo movimento, informou nesta terça-feira a emissora pública "NHK". Hisashi Suito, chefe da divisão de pesquisa da deformação da crosta terrestre da GSI, declarou à emissora japonesa que embora se suponha que as probabilidades de um novo terremoto deveriam diminuir, não acredita que seja assim. Os especialistas consideram que duas placas situadas no litoral nordeste do país, na área onde aconteceu o terremoto de março de 2011, deslizaram mais de 20 metros. Após examinar a atividade sob o mar, observaram que uma das placas se movimentou 95 centímetros para o leste, perto da península de Oshika, na província de Miyagi, que se afundou 120 centímetros no terremoto e subiu 39 desde então. Os cientistas dizem que uma das razões deste movimento, que está afetando uma ampla área desde o sul de Hokkaido (norte) até o centro do país, é liberar estresse geológico. O pesquisador alertou então para a necessidade de estar alerta perante um terremoto similar ao de 2011, que gerou o posterior tsunami que castigou a costa de Tohoku e deixou cerca de 18.000 mortos e desaparecidos.

Marte já teve um oceano maior que o ártico, dizem cientistas da NASA

N vermelho": na verdade, o corpo celeste já abrigou um oceano tão extenso quanto o Ártico.

Em um artigo publicado na revista Science, os pesquisadores explicaram que há cerca de 4,5 bilhões de anos, metade do hemisfério norte do planeta era coberto por água, em profundidades de até 1,6 km. Acredita-se que o oceano se estendia por 19% do planeta.

"Nosso estudo proporciona uma estimativa bastante sólida de quanta água havia no planeta", explica Geronimo Villanueva, autor principal do artigo.

De acordo com os cientistas, a água foi se perdendo conforme a atmosfera marciana decaía, perdendo o calor e a pressão necessária para manter a água, que foi se condensando, em sua forma líquida. Hoje, só restam 13% do volume de água que havia nos oceanos de Marte, sob a forma de calotas de gelo.

“Sabemos hoje que havia enormes corpos de água em Marte: lagos, deltas e mares. Me parece que temos excelentes evidências de que Marte um dia foi habitável, apesar de não temos certeza se já houve habitantes no planeta", disse John, cientista da Universidade Leicester que faz parte da missão Curiosity, da Nasa, ao Guardian.
