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.
On Monday, the 13,000 inhabitants of the town of Zephyrhills, Florida,
only talk about one thing…
In this tiny town, someone bought a
ticket to the U.S. Powerball lottery and won Saturday over U.S. $ 590 million,
the highest accumulated in the history of the lottery in the country.
Still do not know the person who
bought the winning number on a Zephyrhills supermarket.
According to the rules of the draw,
the winner has 60 days to claim the prize of the lottery, which is played in 42
states and the District of Columbia and the territory of the U.S. Virgin
Islands.
Full payment, after taxes, to which
the winner will win mystery is U.S. $ 377 million.
Zephyrhills is a farming village 48
kilometers northeast of the city of Tampa, and is known in the state of Florida
for bottled water is produced with the same name.
The odds of winning the prize are
one in 175 million, and the prize is 12 times larger than the annual budget of
the town of Zephyrhills.
Bishop said the lottery employees
"We are very excited to have a winner in Florida and, like everyone else,
are waiting to appear."
Of course, no shortage of horror

record time.
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
