It Formed 700 Million Years After Our Universe Began, Claim Astronomers New York: Astronomers have discovered a galaxy which they claim is one of the youngest and brightest ever seen right after the cosmic "dark ages', just 700 million years after the beginning of our Universe. The Hubble Space Telescope has captured the image of the infant galaxy with a redshift significantly above 7, using a natural zoom lens, the Nasa said.

SAN FRANCISCO, FEBRUARY 11: US Government scientists have discovered a new way that HIV attacks human cells, an advance that could provide fresh avenues for the development of additional therapies to stop AIDS, they reported on Sunday. The discovery is the identification of a new human receptor for HIV. The receptor helps guide the virus to the gut after it gains entry to the body, where it begins its relentless attack on the immune system.

Abeneficial bacteria, widely found in yogurt, might help the scientists to stop or slow down HIV transmission rate, a recent study has revealed. The research, presented at the Conference on Retroviruses and Opportunistic Infections in Boston this week, was conducted by physicians and scientists of the University of Washington and the University of Rochester Medical Centre to learn more about how the HIV virus survives and spreads from person to person.

In North America, consideration of life cycle environmental, economic and social aspects of buildings is in vogue. This trend is clear in part from the booming memberships of the U.S. and Canadian Green Building Councils and Sustainable Buildings Canada and the growing number of buildings and communities using environmental rating systems.

This report provides an overview of information on the world fertilizer situation in 2007/08 and a forecast till 2011/12. The fertilizer situation is examined in relation to crop production and factors likely to affect the latter. High commodity prices experienced over recent years led to increased production and correspondingly greater fertilizer consumption as reflected in tight markets and higher fertilizer prices at the start of the outlook period. While demand for basic food crops, for high value crops such as fruit and vegetables, for animal products and for crops capable of being used to produce bio-fuels is likely to remain strong, it is expected that increased fertilizer consumption required to support higher levels of production will be adequately catered for by growing supply world wide during the outlook period.

California almonds are a huge food crop in the United States, and land devoted to almond trees is expected to increase another 50% by 2012. But that growth depends in large part on availability of the almonds pollinator, the honeybee. And honeybees are in trouble, according to a report on North American pollinators unveiled by the National Research Council (NRC) of the National Academies.

Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available observations. The characteristics examined include the mean spatial patterns, intraseasonal-to-interannual and ENSO-related variability, convective versus stratiform precipitation ratio, precipitation frequency and intensity for different precipitation categories, and diurnal cycle.
