Ultra-dense galaxies found in early universe

Ultra-dense galaxies found in early universe

New Haven, Conn. — A team of astronomers looking at the universe’s distant past found nine young, unusually compact galaxies, each weighing in at 200 billion times the mass of the Sun. The findings appeared in the April 10 issue of The Astrophysical Journal Letters.

These young galaxies are the equivalent of a human baby that is 20 inches long, yet weighs 180 pounds.

Boost for 'green plastics' from plants

Boost for 'green plastics' from plants

Australian researchers are a step closer to turning plants into ‘biofactories’ capable of producing oils which can be used to replace petrochemicals used to manufacture a range of products.

Scientists working within the joint CSIRO/Grains Research and Development Corporation Crop Biofactories Initiative (CBI) have achieved a major advance by accumulating 30 per cent of an unusual fatty acid (UFA) in the model plant, Arabidopsis.

CSIRO unveils a new class of fatty acids

CSIRO Entomology business manager, Cameron Begley, said researchers believed the discovery opened up an entirely new class of chemistry.

“Some of these alpha-hydroxy polyacetylenic fatty acids act as indicators for a range of different conditions, such as mechanical stress or heat, and display self-assembling properties. Others display anti-microbial properties,” he said.

Ancient Sunflower Fuels Debate About Agriculture in the Americas Researchers at the University of Cincinnati and Florida State University have confirmed evidence of domesticated sunflower in Mexico — 4,000 years before what had been previously believed.

New species discovered in Brazil

Arlington, Virginia (April 29, 2008) – Researchers discovered a legless lizard and a tiny woodpecker along with 12 other suspected new species in Brazil’s Cerrado, one of the world’s 34 biodiversity conservation hotspots.

The Cerrado’s wooded grassland once covered an area half the size of Europe, but is now being converted to cropland and ranchland at twice the rate of the neighboring Amazon rainforest, resulting in the loss of native vegetation and unique species.

Women's biological clock revealed: Hormone may predict age at menopause

Age at menopause may now be predicted more realistically according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM). The study revealed that anti-Müllerian hormone (AMH) levels are related to the onset of menopause and are able to specify a woman’s reproductive age more accurately than chronological age alone.

Nanoengineered barrier invented to protect plastic electronics from water degradation

A breakthrough barrier technology from Singapore A*STAR’s Institute of Materials Research and Engineering (IMRE) protects sensitive devices like organic light emitting diodes (OLEDs) and solar cells from moisture 1000 times more effectively than any other technology available in the market, opening up new opportunities for the up-and-coming plastic electronics sector.

Aspirin-like compounds increase insulin secretion in otherwise healthy obese people

Aspirin-like compounds (salicylates) can claim another health benefit: increasing the amount of insulin produced by otherwise healthy obese people. Obesity is associated with insulin resistance, the first step toward type 2 diabetes.

Aspirin and other salicylates are known to reduce blood glucose in diabetic patients. New research accepted for publication in the Journal of Clinical Endocrinology & Metabolism reveals a similar beneficial effect among obese individuals by increasing the amount of insulin secreted into the bloodstream.
