La risa no es sólo cosa de humanos - Ciencia - Diario de Mallorca
La capacidad de reír no es en absoluto exclusiva de los humanos, según demuestra un estudio comparativo entre niños y primates desarrollado por un grupo de científicos alemanes y americanos.
EFE Los expertos llegaron a la conclusión de que si se le hacen cosquillas a una cría de gorila o de chimpancé, el primate experimenta el mismo ataque de risa que cualquier niño, señala el informe hecho público hoy en Hannover.
Desde tiempos ancestrales, la risa ha supuesto un misterio para la comunidad científica, que ha querido analizar los vínculos entre los humanos y los antropomorfos, una familia de primates en la que se incluyen, entre otros, el chimpancé, el gorila, y el orangután.
"Lo que más nos ha llamado la atención es que las cosquillas produzcan exactamente la misma reacción y sonidos en gorilas y orangutanes", explicó la profesora Elke Zimmermann de la Escuela Superior de Medicina Veterinaria de Hannover (centro de Alemania)...

Bronze Age relics are 'treasures' (From Bradford Telegraph and Argus)
Ancient artefacts dating back 4,000 years dug up by a gardener at a farm near Haworth have been officially recognised as treasure and declared as "unique" at an inquest in Bradford.
Three urns containing an accessory, ceramic vessel, a stone battle axe and a pair of bronze copper alloy earrings were unearthed at Cross Farm, in Stanbury, during landscaping work.
Human bones were found in the largest urn and examinations of the skull suggested they were of a male of high social standing. A belt fastener and a bone pin were also unearthed.
Treasure inquests are held to establish where, when and whether they were found and if items can be classed as treasure.
Deputy assistant coroner Paul Marks recorded that the discoveries were treasure, dating back to the Early Bronze Age, at Bradford Coroner's Court yesterday.
He said it was only the fourth such inquest ever to be heard in Bradford.
Peter Holmes, of Valley View, Harden, a builder, was digging by hand as he carried out landscaping work at Cross Lane Farm on March 12, 2007, when he made the discovery.
He told the inquest: "I was using a shovel when I saw what I thought was a hammer head. So I picked it up and compared it with my hammer and when I realised what it was I stopped working and waited for Mr Mathers (the landowner) to come back."
The item turned out to be a stone battle axe which had been in the broken base of the largest of the three urns.
Phillip Mathers contacted Manor House Museum, in Ilkley, whose staff called Archaeological Services WYAS in Morley.
They excavated two near-complete urns out of the pit. They were x-rayed at the Royal Armouries Museum in Leeds then micro-excavated by conservators at the York Archaeological Trust.
Dr Jane Richardson, senior project manager at Archaeological Services WYAS, said: "It's a very unusual deposit, exceptional. We have never discovered anything like it.
"There are plenty of examples of urns with different objects and a stone battle axe but no single deposit in the country that we know of that has collared urns, bronze earrings and an accessory vessel. The assemblage in its entirety is unique."
She said the entire find dated back to sometime between 1960BC and 1780 BC.
Mr Marks would inform the National Museum of his verdict and the items will be valued by the Treasure Valuation Committee.
The finder and the landowner will receive a reward. If no museum has the desire or money to obtain the items then the finder and landowner will own the objects jointly.

9,000-year-old brew hitting the shelves this summer Scientific American Blog
This summer, how would you like to lean back in your lawn chair and toss back a brew made from what may be the world's oldest recipe for beer? Called Chateau Jiahu, this blend of rice, honey, and fruit was intoxicating Chinese villagers 9,000 years ago -- long before grape wine had its start in Mesopotamia.
University of Pennsylvania molecular archaeologist Patrick McGovern first described the beverage in 2005 in the Proceedings of the National Academy of Sciences based on chemical traces from pottery in the Neolithic village of Jiahu in Northern China. Soon after, McGovern called on Sam Calagione at the Dogfish Head Craft Brewery in Milton, Delaware to do the ancient recipe justice. Later this month, you can give it a try when a new batch hits shelves across the country. The Beer Babe blog was impressed, writing that it is "very smooth," and "not overly sweet."
But that's not the only strange brew Dogfish is shipping out this summer. Next week, the brewery will be bottling up the first large batch of Sah'tea for the general public – a modern update on a 9th century Finnish beverage. In the fall, The New Yorker documented the intricate research and preparation that went into making the beer, which was first offered on tap at the brewery in May. In short, brewmasters carmelize wort on white hot river rocks, ferment it with German Weizen yeast, then toss on Finnish berries and a blend of spices to jazz up this rye-based beverage. Reviewers at the BeerAdvocate universally praised Sah'tea, comparing it to a fruity hefeweizen. One user munched on calamari as he downed a pint and described the combo as "a near euphoric experience."...

Skulls vs. DNA: Zeroing In on American Origins Wired Science Wired.co
"We don't know how people got to the New World, when, or who they were," said anthropologist Judith Habicht-Mauche at the University of California, Santa Cruz. "Those questions are very much up for grabs right now and very controversial."
The controversy centers around two conflicting sets of data. Studies of skull shapes noted that people in South America 14,000 years ago looked different from the people that were there 8,000 years ago and from modern Native Americans. Some anthropologists think that means there were at least two migrations to South America. The first group, Paleoamericans, had long narrow skulls and small eye sockets and was closely related to Northeast Asians. The second, Amerindians, had short broad faces, larger eye sockets, and was related to Southeast Asians.
But the molecular data disagrees. Studying modern people's mitochondrial DNA, which is inherited from the mother, suggests all the Native Americans in South America split off from a single Northeast Asian group that migrated over about 15,000 years ago...
