Prehistoric skull a key 'piece of the puzzle' in story of humanity

Researchers work inside Manot Cave in Israel's Western GalileeBy Will Dunham WASHINGTON (Reuters) - A partial skull retrieved from a cave in northern Israel is shedding light on a pivotal juncture in early human history when our species was trekking out of Africa to populate other parts of the world and encountered our close cousins the Neanderthals. The researchers said characteristics of the skull, dating from a time period when members of our species were thought to have been marching out of Africa, suggest the individual was closely related to the first Homo sapiens populations that later colonized Europe. They also said the skull provides the first evidence that Homo sapiens inhabited that region at the same time as Neanderthals, our closest extinct human relative. Tel Aviv University anthropologist Israel Hershkovitz, who led the study published in the journal Nature, called the skull "an important piece of the puzzle of the big story of human evolution." Previous genetic evidence suggests our species and Neanderthals interbred during roughly the time period represented by the skull, with all people of Eurasian ancestry still retaining a small amount of Neanderthal DNA as a result.

'Expensive' placebo beats 'cheap' one in Parkinson's disease: study

By Sharon Begley NEW YORK (Reuters) - When patients with Parkinson's disease received an injection described as an effective drug costing $1,500 per dose, their motor function improved significantly more than when they got one supposedly costing $100, scientists reported on Wednesday. The research, said an editorial in the journal Neurology, which published it, "takes the study of placebo effect to a new dimension." More and more studies have documented the power of placebos, in which patients experience an improvement in symptoms despite receiving sugar pills, sham surgery, or other intervention with no intrinsic therapeutic value. Earlier studies have shown that patients' expectations can lead to improvements in Parkinson's, a progressive motor disease in which the brain's production of dopamine plummets. As it happens, dopamine release is increased by belief, novelty, and the expectation of reward - mental states that underlie placebo effects, said neurologist Alberto Espay of the University of Cincinnati, who led the new study.

How these energy geeks are reimagining an old school utility

Electric cars sit charging in a parking garage at the University of California, IrvineBy Nichola Groom Orange County, Ca (Reuters) - Welcome to the utility industry's future - or at least that's what Southern California Edison is hoping.     Here in a non-descript, 53,500-square-foot building, the $12 billion utility's research team is testing everything from charging electronic vehicles via cell phone to devices that smooth out the power created by rooftop solar panels.     Those are some of the roughly 60 projects in the works at Edison's Advanced Technology division. The engineers from California's largest utility are hatching plans to insure its survival - and maybe even the survival of the nation's other big utilities, which are watching the project closely.     The lab was formed by Southern California Edison in 2009 after California passed a landmark law to lower its greenhouse gas emissions to 1990 levels - and source one third of its electricity from renewable sources by 2020.     The result has been more electric vehicles here in the Golden State.

Remarkable fossils push back snake origins by 65 million years

An artist rendering from oldest-known snake fossilsBy Will Dunham WASHINGTON (Reuters) - Snakes have been slithering on Earth far longer than anyone ever realized. Scientists on Tuesday described the four oldest-known snake fossils, the most ancient of which was a roughly 10-inch-long (25 cm) reptile called Eophis underwoodi unearthed in a quarry near Oxford, England, that lived about 167 million years ago. The remarkable fossils from Britain, Portugal and the United States rewrite the history of snake evolution, pushing back snake origins by tens of millions of years. Until now, the oldest snake fossil dated from about 102 million years ago, said University of Alberta paleontologist Michael Caldwell, who led the study published in the journal Nature Communications.

Crashing Electrons Could Explain Earth's Magnetic Field Mystery

Crashing Electrons Could Explain Earth's Magnetic Field MysteryA messy paradox that has plagued geoscientists who study Earth's core and the magnetic field it produces may now be solved. It was raised in a 2012 paper in which geophysicists in the United Kingdom published a widely accepted supercomputer model that found Earth's iron core was incredibly efficient at conducting heat. In that study, the researchers examined how heat may move through the Earth's core, at the level of atoms and electrons. The implication: Earth's magnetic field shouldn't exist.

Building a better weather forecast? SMAP may help

If you were trying to forecast tomorrow's weather, you would probably look up at the sky rather than down at the ground. But if you live in the U.S. Midwest or someplace with a similar climate, one key to a better weather forecast may lie beneath your feet. Better soil moisture observations are just what the Soil Moisture Active Passive (SMAP) mission will provide. Scheduled for launch on Jan. 29, SMAP will collect the most accurate and highest-resolution soil moisture measurements ever made from a satellite SMAP will cover the entire globe in two to three days.
