A recent dating and surprising   The results indicate that they date back 28,500 years, 8000 years after the alleged disappearance of Neanderthal Man. At this time we find, throughout Eurasia, that crop-specific Upper Paleolithic Homo Sapiens explains Ludovic Slimak.   This discovery raises many questions about the users of the Mousterian culture near the […]

In an article published in Molecular Biology and Evolution, Damian Labuda, Department of Pediatrics, University of Montreal (Quebec), indicates that it has identified on chromosome X a section of DNA different from the others who made comparison , seems to be a Neanderthal heritage. This sequence is found among peoples of all continents, including Australia, […]

Japan, One Year After: The Legacy Of A Historic Earthquake

Another promising strategy is the development of the self-powered micro-missiles with enzymes as catalysts. These consist of rolled titanium-gold layer and the enzyme catalase, which is common in animal cells and hydrogen peroxide decomposes into oxygen and water very effectively. Thus the driving force is increased significantly so that will be ten times higher speeds […]

Blackbird Dying:Tropical Usutu Virus Kills Birds

By Tracy Kelly /

This new method combines actually two types of technology used to produce electricity: a microbial fuel cell and a reverse electrodialysis system. Two methods inefficient because with a yield too low or too high manufacturing cost. But by associating it can overcome the limitations of individual technologies, said Bruce E. Logan, professor of environmental engineering. […]

Danger To Prey Around Protected Areas

By Tracy Kelly /

These refuges attract game but also, at their periphery, human predators, which can make these reservations riskier for animals than it seems.   Protected areas where animals can live free of human-induced risks are they effective? Not necessarily meet a French-Swiss team which includes researchers from the Laboratory of Alpine Ecology. To assess their role […]

A Whirlwind Of 20 Km High

By Tracy Kelly /

In three minutes, estimated duration of the earthquake, the crust broke about 500 km long and 150 km wide. The many GPS stations have constituted a map of ground motions: the east coast of the island slipped four meters while the West has moved only a few tens of centimeters The earthquake was followed by […]

Prostate Cancer: Which Test Is Controversial

By Tracy Kelly /

These results also suggest that interbreeding between early modern humans and Neanderthals took place long ago, after Homo sapiens left Africa but before it disperses in Europe and Asia. Damian Labuda traces the intimate contact or family ties of these two populations very far in history, probably at a crossroads in the Middle East. Thin […]

Billions Of Rocky Planets In The Milky Way

By Tracy Kelly /

A sequence found in all regions except sub-Saharan Africa The comparison between human DNA and that of Neanderthal man, recently deciphered (1) , showed that there had been a cross between these two species and that Homo Sapiens have fond memories in their genome since it would consist of 1 to 4% of Neanderthal DNA […]
