Natural gas ( methane ) has a greater global warming impact than carbon dioxide but conventional cellulose acetate membranes in processing plants lose natural gas in their waste products.

Thermally rearranged (TR) plastic works four times better than conventional membranes at separating out carbon dioxide, say University of Texas at Austin researchers. Dr. Ho Bum Park, a postdoctoral student in the laboratory of Professor Benny Freeman, also found that TR plastic membranes act quicker.

The genome analysis of this tiny green alga has uncovered hundreds of genes that are uniquely associated with carbon dioxide capture and generation of biomass.

Among the 15,000-plus genes revealed in the study are those that encode the structure and function of the specialized organelle that houses the photosynthetic apparatus, the chloroplast, which is responsible for converting light to chemical energy. The genome also provides a glimpse back through time to the last common ancestor of plants and animals.

Red wine is known to have multiple health benefits. Researchers at the University of Missouri-Columbia have found that red wine may also protect humans from common food-borne diseases, even E. coli.

Researchers Azlin Mustapha, associate professor of food science in the College of Agriculture and doctoral student Atreyee Das are conducting on-going studies examining the inhibitory effects of red wines and grape juice against pathogens and probiotic bacteria, which naturally reside in the intestinal tract and can be beneficial in combating, among other things, high cholesterol and tumors.

New research funded by the Economic and Social Research Council (ESRC) examines the motivations and practices of consumers and producers involved in ‘alternative food’ networks like organic vegetable boxes, community gardens and farm animal adoption and says consumers tended to increase their consumption of fruit and vegetables, and improve their cooking skills and knowledge about food.

The research also found some evidence of a ‘graduation effect’, whereby involvement in an alternative food scheme encouraged consumers to change their consumption behaviours in relation to other goods, such as household products and clothes.

Although the majority of consumers use alternative food sources alongside supermarkets, they often felt that the quality of supermarket food was inferior.

Ilia Ivanov and Dave Geohegan of Oak Ridge National Laboratory's Nanomaterials Synthesis and Properties Group have been collaborating with John Simpson of the Superhydrophobic Materials Group and Cheol Park and Joycelyn Harrison of the National Institute of Aerospace in NASA's Langley Research Center to produce a Flexible, Integrated, Lightweight, Multifunctional skin, called FILMskin, for next-generation prosthetic hands and arms.

A report to be published in an upcoming issue of the World Health Organisation (WHO) Bulletin will call for urgent attention to the politically sensitive issue of border control, and the need for coherent and robust national plans in the face of a catastrophic flu pandemic .

The report comes after the recent confirmation of person-to-person transmission of a strain of avian influenza A (HN51) in Northern Sumatra: although the outbreak was contained by voluntary quarantine and rapid administration of antiviral medication, scientists admitted that the world had ‘dodged a bullet’ and ‘may not be so lucky next time.

“Governments need to work with their neighbours, sharing best practices and strategic thinking openly.
