Wheat   Eyewire Farming origins gain 10,000 years  - BBC  Left:  Wild types of emmer wheat like those found at Ohalo were forerunners of today's varieties.  Humans made their first tentative steps towards farming 23,000 years ago, much earlier than previously thought. Stone Age people in Israel collected the seeds of wild grasses some 10,000 years earlier than previously recognised, experts say. These grasses included wild emmer wheat and barley, which were forerunners of the varieties grown today. Archaeologists have also found huts, camp fires, a human grave and stone tools at the site. Most of the evidence points to the Near East as the cradle of farming. Indeed, the principal plant foods eaten by the people at Ohalo appear to have been grasses, including the wild cereals emmer wheat and barley. Grass remains also included a huge amount of small-grained wild grasses at Ohalo such as brome, foxtail and alkali grass. However, these small-grained wild grasses were to disappear from the human diet by about 13,000 ago. Anthropologists think farming may have started when hunter-gatherer groups in South-West Asia were put under pressure by expanding human populations and a reduction in hunting territories. This forced them to rely less heavily on hunting large hoofed animals.
Pathways To Chemical Evolution In Space - SpaceDaily  Left:  Diagram of the 10-atom molecule propanal and the 8-atom molecule propenal.  The 8-atom molecule propenal and the 10-atom molecule propanal were detected in a large cloud of gas and dust some 26,000 light-years away in an area known as Sagittarius B2.  "Though very rarefied by Earth standards, these interstellar clouds are the sites of complex chemical reactions that occur over hundreds-of-thousands or millions of years," said Jan M. Hollis of the NASA Goddard Space Flight Center in Greenbelt, Md. "Over time, more and more complex molecules can be formed in these clouds."

New Version Of Global Climate Model Released - SpaceDaily  The National Center for Atmospheric Research (NCAR) in Boulder, Colo., is unveiling a powerful new version of a supercomputer-based system to model Earth's climate and to project global temperature rise in coming decades. The system, known as the Community Climate System Model, version 3 (CCSM3), indicates in a preliminary finding that global temperatures may rise more than the previous version had projected if societies continue to emit large quantities of carbon dioxide into the atmosphere. CCSM3 shows global temperatures could rise by 2.6 degrees Celsius (4.7 degrees Fahrenheit) in a hypothetical scenario in which atmospheric levels of carbon dioxide are suddenly doubled.
