The discovery of DNA in a 400,000-year-old human thigh bone will open up a new frontier in the study of our ancestors.
That's the verdict cast by human evolution experts on an analysis in Nature journal of the oldest human genetic material ever sequenced.
The femur comes from the famed "Pit of Bones" site in Spain, which gave up the remains of at least 28 ancient people. But the results are perplexing, raising more questions than answers about our increasingly complex family tree.

US Shutting Down a Key News Source
This New Year’s Eve, the Office of the Director of National Intelligence will quietly deliver a devastating blow to the American public’s access to accurate, unbiased information that is unparalleled in quality and comprehensiveness by shutting off access to the World News Connection.
WNC is a valuable trove of U.S. government-sponsored media translations and analyses that has informed the work of American scholars, journalists, writers and historians for the past six decades. It is one of the few offices in the U.S. intelligence community that regularly shares information with the people, rather than simply extracting metadata about them.

Since 2009, more than 200 magnitude-3.0 or greater earthquakes have hit the state's midsection, according to the Geological Survey. Many have been centered near Oklahoma City, the most populous part of the state.
Where are the smartest 15-year-olds in the world?
The academic performance of 15-year-olds in the United States has stayed relatively the same in recent years, but with other nations improving, American students are slipping behind their international counterparts, according to a study released Tuesday.
The National Center for Education Statistics (NCES) released data on the 2012 academic performance of 15-year-olds around the world in three subjects: reading, mathematics, and science.
"We are not seeing any improvement in the U.S. … our ranking is slipping because other countries are improving," said Jack Buckley, NCES commissioner.
Researchers Discover the Hot New Technology: Throwing Javelins
iPhones, staplers, aluminum foil. Humans are surrounded and defined by their technologies. We might even say: Technology makes us human.
But that’s not quite true, because we know that other animals employ and deploy tools, too. Primates use twiggy Roto-Rooters to search for bugs. All sorts of creatures make homes for themselves; bowerbirds sculpt fantastical ones.
And now we know it’s not quite true either, historically. New archeological evidence indicates that our ancestors used a certain kind of tool—a “complex tool,” in the parlance of anthropologists—when they were still our ancestors.
That is: They threw spear-tipped javelins, to catch and kill animals.
Immune system may play crucial role in mental health
A growing body of research on conditions from bipolar disorder to schizophrenia to depression is starting to suggest a tighter link than was previously realized between ailments of the mind and body. Activation of the immune system seems to play a crucial role in both.
"We just didn't understand how much of a role the immune system plays in how we think and feel and act," says Andrew Miller, a professor of psychiatry at Emory University. "An overactive immune system or when there's something going on in the immune system, it can have consequences on the brain."
Large protests over Bedouin resettlement in Israel
Large protests over a plan to resettle nomadic Bedouin Arabs in Israel's southern Negev desert caused injuries Saturday and led to some arrests as well as condemnation from Prime Minister Benjamin Netanyahu.
Protests focused on a bill that would move thousands of Bedouins into government-recognized villages. Opponents charge the plan would confiscate Bedouin land and affect their nomadic way of life, but Israel says the moves are necessary to provide basic services that many Bedouins lack and would benefit their community while preserving their traditions.
Unforgotten fighter of Korean war: U.S. pensioner a POW at 85
As autumn descended on a Korean countryside devastated by three years of intense war, a group of anti-communist guerrillas presented U.S. serviceman Merrill Edward Newman with a gold ring. It was September, 1953.
For Newman, the ring became a proud symbol of the role he played as an adviser to a group of battle-hardened partisans who fought deep behind enemy lines in a war that pitted the China- and Soviet-backed North against the U.S.-backed South.
Alex Baer: Thankful for Being Able to Be Grateful for Gratitude
Yesterday was the official day of handing out our thanks to anyone who would listen. With luck, we not only thought about doing that, but actually did so. Out loud. And, with even more luck, we also had some takers, in between thunderclaps of footballer collisions from our Big Scream teevees, and the assorted sonic booms of industry and inventiveness erupting from kitchen and guests.
You might have even been so lucky as to have been heard above the acoustic carnage of the day, and, luckier still, to have received knowing, thoughtful, insightful, and sincere replies along the same lines.
I mean, I can wish that such becalmed seas ferried you along softly and sweetly yesterday, and in the golden photographer's light of dawn or dusk, all the while sipping a profoundly satisfying adult entertainment beverage, but the odds are pretty much against it, I'd imagine -- like hoping Aunt Smelda would please, please forget to bring over her famous Jell-O mold, with odd bits of things suspended in the gelatin (some identifiable and mostly edible, others of a baffling, mysterious origin) like a forgetful, absent-minded cook's version of bugs trapped in amber.
