'First of our kind' found in Morocco

The idea that modern people evolved in a single "cradle of humanity" in East Africa some 200,000 years ago is no longer tenable, new research suggests. 
Fossils of five early humans have been found in North Africa that show Homo Sapiens emerged at least 100,000 years earlier than previously recognised. 
It suggests that our species evolved all across the continent, the scientists involved say. 
Prof Hublin's excavation has further revealed that these ancient people had employed stone tools and had learned how to make and control fire. So, not only did they look like Homo Sapiens, they acted like them as well.
So,this prooves that the history that we know can change from a day to other with discoveries like this,and remember us that not all that we know can be 100% truth.

Antarctic ice crack takes major turn

The fissure, which threatens to spawn one of the biggest bergs ever seen, has dramatically changed direction.
The rift has propagated a further 16km, with a significant apparent right turn towards the end, moving the tip 13km from the ice edge.The fissure currently extends for about 200km in length, tracing the outline of a putative berg that covers some 5,000 square km , an area about a quarter of the size of Wales.
Were the shelf to collapse (and even if it did, it would still take many years to complete), it would continue a trend across the Antarctic Peninsula.
Summarizing, the antartida is breaking, it is melting and it seems that we continue to ignore it, we will see what happens, but it goes from bad to worse.

Overpass the 100 years?

Overcoming the threshold of 100 years with acceptable health or being young again may be possible thanks to science.
The objective of the researchers is to create a drug that allows humans to completely regenerate all their cells, because they point out that "what is important is not age or time, but that life time is as healthy as possible."
At the moment, they have experimented with mice obtaining very good results.
The pathologies are delayed and the mice live much longer because they are more time younger, so if the mice treated were humans, they would have an iron health that would allow them to live to 120 years.
So, maybe, in a future, the human will live 110 or 120 years.

Tattoos: The good, the bad and the bumpy

The body art might appear cool, but it can pose risks. Some people react badly to the inks-substances that aren’t meant to go on or in the body. Other people may have trouble getting certain medical tests after a tattoo. And not everyone is as thoughtful when they are selecting their design. Many people get inked on a whim, and later want that permanent art removed. It can be done, but it’s a long and painful process.
Still, research now indicates tattoos aren’t bad for everyone. In people who heal well, getting a tattoo may prime their germ-fighting immune systems for action,and in a good way. The rub: Until someone gets a tattoo, there’s no way to know if they will be someone who benefits or instead be harmed.

They discover a new planet,the best candidate to find extraterrestrial life

 In the last days, there have been discovered a lot of planets that could have life in it.The list of potentially life-enhancing planets increases steadily. And the title of best candidate to be a habitable world is going from one to another planet as scientists manage to refine, a little more, their search for a twin of the Earth.
And, they have discovered yes,another planet that has the title of best candidate.
This planet, rocky and 40 light-years away, it is located in the habitable zone of its star.The new world is something bigger than ours and much more massive,this world could have a good atmosphere so theres a great hope to find life here.
News like this, show us that extraterrestrial life is very possible,maybe intelligent life.

Why tomatoes of the present have no taste?

They may have a bright red color and an almost perfect shape, but most of the time, tomatoes have no taste at all.
At which point the tomatoes ceased to have taste and why?
After the post-war period, countries put great emphasis on increasing production to meet the needs of the population,They introduced resistance genes to diseases present in traditional varieties,backcrossing the varieties they liked and discarding things that did not interest them.
The implementation of these improvements resulted in more pest-resistant tomatoes, colorful, homogeneous in size and resistant to transport and storage, buuuuut, they lost their taste.This was involuntary,they didn't know where the taste of the tomatoes were.
Fortunately, they've discovered new genes that could recover the taste of tomatoes,so,there's hope for the future.

Carrefour stops selling panga in Spain

Earlier this week, the Belgian division of Carrefour reported through a statement that it stopped putting on sale panga because of environment reasons.

The French source explained that while the quality of the poultry offered for sale was "flawless", there were doubts about the control mechanisms of the farms where it is grown (the vast majority in Vietnam) to prevent waste from polluting its waters.

Spain, deficient in trade of fish, is the EU country that more panga imported in 2015
