09/12/16. Francia inaugurará el sábado una nueva réplica de la célebre cueva de Lascaux, hogar de extraordinarias pinturas prehistóricas de 18.000 años, descubiertas hace más de 75 años por cuatro adolescentes.

"¡Es una maravilla! Tuve la impresión de estar dentro de la verdadera cueva", afirmó entusiasta Simon Coencas, último superviviente de los cuatro muchachos que descubrieron esta famosa caverna en el suroeste de Francia el 12 de septiembre de 1940, en plena ocupación nazi. 

Coencas, de 89 años, estará el sábado junto al presidente de Francia, François Hollande, en la ceremonia de inauguración oficial de "Lascaux 4", que abrirá al público el 15 de diciembre...

... En la nueva réplica, que reproduce integralmente las pinturas de la cueva de Lascaux a escala real, los visitantes podrán ver copias exactas de todos dibujos realizados hace 18.000 años y que desde 1979 hacen parte de la lista de Patrimonio mundial de la Unesco. 

El objetivo de este nuevo proyecto científico, artístico y turístico, realizado en un espacio de 8.500 m2, es hacer sentir a los visitantes las "mismas emociones" que tuvieron los cuatro adolescentes que descubrieron por casualidad el excepcional santuario prehistórico.[...] noticias.terra.com.ar

Actualización: France opens new Lascaux prehistoric art cave replica

 
AFP. A new replica of the stunning Lascaux cave paintings was unveiled Saturday in the Dordogne region of southwest France, more than seven decades after the prehistoric art was first discovered.

"This is more than a copy, it's a work of art!" said French President Francois Hollande as he visited the centre in Montignac, the village at the foot of the hills where the original cave complex is located.

The new project dubbed "Lascaux 4", which opens to the public on Thursday, aims to recreate the sensations experienced by the four teenage boys who found the cave on September 12, 1940.

The last of the boys still alive is Simon Coencas, now 89, who was a special guest at Saturday's event.

With World War II raging and the Nazis already in Paris, a friend of Coencas had enlisted him and the other boys to explore a hole in the ground in the hills above their village that his dog had found a few days earlier...

Le cerveau fossile d’un homme de Néandertal, exposé pour la première fois au public

Il est très rare et son prix est inchiffrable. Le cerveau fossile d’un homme de Néandertal, caché pendant des dizaines d’années dans les dépositaires du Musée national à Prague, est une découverte unique en son genre au monde. Cet objet précieux est présenté pour la toute première fois au public dans le cadre d’une exposition au Musée morave de Brno.

A première vue, le contenu de la boîte crânienne fossile d’un homme de Néandertal est un objet discret qui ressemble à une pierre. Cependant, il est placé dans une vitrine incassable et il est rigoureusement surveillé. Ce cerveau, qui date de quelque 105 000 ans, a été découvert en 1926 dans les environs du village de Gánovce en Slovaquie. Cette trouvaille a ensuite permis aux chercheurs de prouver la présence de l’homme de Néandertal en Europe centrale.

Jusqu’à présent, le fossile était resté dans les trésors du Musée national à Prague. Ce n’est que 90 ans après sa découverte qu’il est finalement exposé au public, dans le cadre d’une exposition organisée à l’occasion du 200e anniversaire de la fondation du Musée morave de Brno...

North America’s oldest mummy returned to US tribe after genome sequencing

DNA proves Native American roots of 10,600-year-old skeleton.

The sequencing of a 10,600-year-old genome has settled a lengthy legal dispute over who should own the oldest mummy in North America — and given scientists a rare insight into early inhabitants of the Americas.

The controversy centred on the ‘Spirit Cave Mummy’, a human skeleton unearthed in 1940 in northwest Nevada. The Fallon Paiute-Shoshone Tribe has long argued that it should be given the remains for reburial, whereas the US government opposed repatriation. Now, genetic analysis has proved that the skeleton is more closely related to contemporary Native Americans than to other global populations. The mummy was handed over to the tribe on 22 November.

The genome of the Spirit Cave Mummy is significant because it could help to reveal how ancient humans settled the Americas, says Jennifer Raff, an anthropological geneticist at the University of Kansas in Lawrence. “It’s been a quest for a lot of geneticists to understand what the earliest peoples here looked like,” she says.

Development of new techniques makes it possible to date Australian Aboriginal rock art

A new technique, developed at ANSTO’s Centre for Accelerator Science, has made it possible to produce some of the first reliable radiocarbon dates for Australian rock art in a study just published online in The Journal of Archaeological Science Reports.

The approach involved extracting calcium oxalate from a mineral crust growing on the surface of rock art from sites in western Arnhem Land, according to paper co-author research scientist Dr Vladimir Levchenko, an authority on radiocarbon dating using accelerator mass spectrometry.

Levchenko, who supervised the radiocarbon dating, collaborated with lead author of the paper, Ms Tristen Jones, a PhD candidate at the Australian National University (ANU) and co-authors from ANU.

Generally speaking, radiocarbon dating cannot readily be used to date Australian indigenous rock art directly, because it is characterised by the use of ochre, an inorganic mineral pigment that contains no carbon.

The paper authors explain that carbon found in the mineral crusts on the rock surface was most probably was formed by microorganisms.

“These microorganisms are photosynthetic bacteria, like cyanobacteria or algae, which can utilise carbon from the air normally, and are active through wet periods,” said Levchenko.

One of the peer review authors who reviewed the paper prior to publication predicted it could become a benchmark for studies of this type as it addressed a complete lack of chromometric data for rock art in Australia and elsewhere.

Another reviewer called it the most significant rock art and dating paper to have been produced in Australia for over 25 years. [...] ANSTO / Link 2 

Tibetan dogs can survive at high altitudes, thanks to ancient breeding with wolves

Tibetan mastiffs thrive where most dogs and people can’t: in the thin, frigid mountain air above 4000 meters. A new study suggests they acquired this talent by interbreeding with gray wolves that already ranged to such heights more than 20,000 years ago. Intriguingly, Tibetan people received their high-altitude fitness via the same mechanism—by interbreeding with now extinct humans known as Denisovans. The study adds to growing evidence that such ancient mating events have sometimes played a vital role in the adaptation of modern species to their environments, the scientists say.

“It’s a very cool discovery … which turns out to be a mirror of what’s going on with the humans [there],” says Elaine Ostrander, a geneticist at the National Institutes of Health in Bethesda, Maryland, who was not involved with the study.

An early type of dog from China’s lowland regions likely traveled to the Tibetan Plateau with people about 24,000 years ago, says study author Zhen Wang, a geneticist at the Shanghai Institutes for Biological Sciences in China. And like those humans, the lowland dogs “adapted in a relatively short time” to the high life, ultimately becoming today’s shaggy, large-boned mastiffs. During that transition, they acquired various traits that helped them endure the harsh, icy winters and limited supply of oxygen. [...] Science | AAAS / Link 2
