Archaeologists in Mexico found 4,926 well-preserved rock paintings in caves in the town of Burgos, in the state of Tamaulipas.

There are also abstract strokes.

The paintings were found in eleven different places. In one of the caves the walls were covered with 1,550 scenes.

The drawings suggest that at least three groups of hunters lived in the Sierra de San Carlos, in northeastern Mexico.

By the time the experts have not been able to determine the age of the paintings, but expect a chemical analysis to define an approximate date.

The drawings are considered as an important finding because it documented the presence of a pre-Hispanic civilization in a region where "previously said that there was nothing," Ramirez said.

Another archaeologist who participated in the investigations of the INAH, Martha Garcia Sanchez, said little is known about the cultures that inhabited Tamaulipas.

These groups escaped from Spanish rule for 200 years because they went to the Sierra de San Carlos, where they had water, plants and animals for food, "she explained.

The discovery was presented at the Second Meeting of Historical Archaeology at the National History Museum of Mexico.

The 2014 World Cup in Brazil was conceived as a great party to showcase the economic strength of this country, but someone determined to tell another story to Brazilians: the current exastro football and national deputy Romario.

With his constant criticism of the costs of the event, reports of dark dealings in Brazilian football and doubts about the fate of the national team, Romario has become the spoiler of the 2014 World Cup.

Far from dull the luster of this exgoleador and former World Champion with Brazil in 1994, his attitude about the organization of the World Cup and domestic football Romario gave a screening policy that few imagined.

Romario was elected deputy for the Brazilian Socialist Party (PSB) in 2010, only two years after announcing the end of a long career as a player in which surpassed the 1,000 goals.

When asked why he chose politics, often said that he did after his daughter was born with Down syndrome and discovered that people with disabilities need a representative in Brazil.

According Romario, who chairs the committee of Tourism and Sports in the Lower House, the problem is not that the World Cup was made in Brazil but has been accepted many of the conditions that raised the Cup.

"Brazil will spread her legs to FIFA," he said.

They are looking for someone with deep voice scare polar bears.

Are you one of those people who speaks so loudly that every now and then someone makes a hand gesture to ask you to lower your voice?

If so, the authorities of the Svalbard archipelago have a job for you.

The governor of the Norwegian archipelago in the Arctic took a notice in which a person seeks to remain vigilant and report-out loud-if about a polar bear, while a team of scientists conducted their research .

And is that unlike other regions of the world where the polar bear population is declining due to climate change, in Svalbarg bear numbers are growing.

It is estimated that there are about 3,000 polar bears in the area and only 2,400 inhabitants.

If you move within human settlements, is unlikely to run into one of these creatures. But outside these limits the possibilities are greater. And, as explained by one of the Norwegian Polar Institute brochures, these imposing animals weighing between 400 and 600 kilos, and reaches speeds up to 30 miles per hour, can become dangerous.

Usually polar bears do not see us as food. However, they are naturally curious and review all that is within reach for food.

Scientists discovered by surprise in laboratory tests that vitamin C can destroy a type of tuberculosis (TB) drug resistance.

The authors of the study, published in the journal Nature Communication, consider this finding may offer new ways to attack the infection increasingly difficult to treat.

An estimated 650,000 people worldwide have drug-resistant tuberculosis.

The next step is to determine if a treatment that works with the same action that vitamin C can serve as a drug of TB in humans.

In laboratory studies, vitamin C, or ascorbic acid, seemed to act as a "reducing agent", which served as a trigger for the production of highly reactive molecules known as free radicals. These killed TB bacteria, including those which cannot be treated with conventional antibiotics such as isoniazid.

The lead researcher, William Jacobs, professor of microbiology and immunology at Albert Einstein College of Medicine of Yeshiva University in New York, said he could only prove this in trial and added: "We do not know if it will work in animals and humans ".

It is possible that vitamin C reaches used with drugs against the disease. Alternatively, scientists could create new drugs that work to generate a great burst of free radicals.

Vitamin C has many important functions in the body, including to protect and maintain healthy cells
