Ancient Bones That Tell a Story of Compassion


http://www.nytimes.com/2012/12/18/science/ancient-bones-that-tell-a-story-of-compassion.html?pagewanted=all&_r=0




And some archaeologists are suggesting a closer, more systematic look at how prehistoric people — who may have left only their bones — treated illness, injury and incapacitation. Call it the archaeology of health care.
The case that led Lorna Tilley and Marc Oxenham of Australian National University in Canberra to this idea is that of a profoundly ill young man who lived 4,000 years ago in what is now northern Vietnam and was buried, as were others in his culture, at a site known as Man Bac.
Almost all the other skeletons at the site, south of Hanoi and about 15 miles from the coast, lie straight. Burial 9, as both the remains and the once living person are known, was laid to rest curled in the fetal position. When Ms. Tilley, a graduate student in archaeology, and Dr. Oxenham, a professor, excavated and examined the skeleton in 2007 it became clear why. His fused vertebrae, weak bones and other evidence suggested that he lies in death as he did in life, bent and crippled by disease.
They gathered that he became paralyzed from the waist down before adolescence, the result of a congenital disease known as Klippel-Feil syndrome. He had little, if any, use of his arms and could not have fed himself or kept himself clean. But he lived another 10 years or so.
They concluded that the people around him who had no metal and lived by fishing, hunting and raising barely domesticated pigs, took the time and care to tend to his every need.
“There’s an emotional experience in excavating any human being, a feeling of awe,” Ms. Tilley said, and a responsibility “to tell the story with as much accuracy and humanity as we can.”

rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates.

The alien planet, a so-called "super-Earth," is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet's mass and radius, and studying its host star's composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates.
At least a third of the planet's mass is likely pure diamond.
"This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth," lead researcher Nikku Madhusudhan of Yale University said in a statement. "The surface of this planet is likely covered in graphite and diamond rather than water and granite."

Odd! Birds Screech at Avian Funerals


Odd! Birds Screech at Avian Funerals


When confronting a dead jay splayed out on the ground, the birds dashed to a tree and began a series of loud, screeching calls to attract other jays, which joined and added their voices to the choir. Iglesias found that these shrieking sessions could last from a few seconds to as long as 30 minutes.

Denisovan genome


A number of these changes influence genes linked with brain function and nervous system development, leading to speculation that we may think differently from the Denisovans. Other changes are linked with the skin, eyes and teeth.

Hyraxes found to sing with varying syntax


Quote:

Hyraxes' songs have something rarely found in mammals: syntax that varies according to where the hyraxes live, geographical dialects in how they put their songs together.

Ancient life, potentially millions of years old and barely alive, found beneath ocean floor


Quote:
Call it survival of the slowest: Extraordinarily old, bizarrely low-key bacteria have been found in sediments 100 feet below the sea floor of the Pacific Ocean, far removed from sunlight, fresh nutrients and what humans would consider anything interesting to do. 
Some of these organisms, scientists say, could be at least 1,000 years old. Or maybe millions of years.

Ancient antibiotic-resistant bacteria found in isolated cave

http://www.cbc.ca/news/technology/story/2012/04/13/science-antibiotic-resistant-bacteria.html

Bacteria that have never before come in contact with humans, their diseases or their antibiotics, but are nevertheless resistant to a variety of antibiotics, have been discovered in a U.S. cave.
