Oldest known star discovered

From ABC Science News Online, 10 February 2014: Astronomers have discovered the oldest known star, born in the fiery wake of a first generation supernova after the Big Bang. The star, with the catchy name SMSS J031300.362670839.3, came to the attention of an international team of astronomers because of its unique chemical fingerprint showing it Continue reading Oldest known star discovered

Microbial duo boost biofuel production

From ABC News in Science, 2o August 2013: Researchers have paired up a fungus and a bacteria to produce high-quality biofuel from agricultural waste materials such as corn stalks and leaves. Using the fungus Trichoderma reesei and the common bacteria Escherichia coli, US researchers were able to produce 1.88 grams of the biofuel isobutanol, per Continue reading Microbial duo boost biofuel production

Trained brains become more efficient

From ABC News in Science, 5 August 2013: A study on monkeys has called into question the fundamental assumption that an active neuron is a hungry one; an assumption that underlies brain imaging techniques such as fMRI. Researchers compared levels of neuron activity and the amount of glucose uptake in the primary motor cortex of Continue reading Trained brains become more efficient

Degrees of learning in the genes

From ABC News in Science, 31 May 2013: It’s not quite the ‘smart gene’ but researchers have identified a small number of genetic markers associated with educational attainment. A genome-wide association study using genetic data from more than 100,000 individuals found three genetic markers that were significantly linked to an individual’s numbers of years of Continue reading Degrees of learning in the genes

Early life of the West Australian dhufish

From Fish magazine, March 2013: For a fish as prevalent and important as the West Australian Dhufish, its offspring have remained under the research radar for a remarkably long time. Endemic to Western Australia, the Dhufish (Glaucosoma hebraicum) is a favourite of recreational and commercial fishers. But, until recently, little was known about its eggs Continue reading Early life of the West Australian dhufish

Genetic technology in the management of wild fisheries

From Fish magazine, March 2013: A new FRDC report examines the role that current and developing genetic technologies can play in addressing some of the key issues involved in the exploitation of wild fisheries. Genetic technology provides a powerful new tool to understand how wild fish populations live, grow and change, and help ensure the Continue reading Genetic technology in the management of wild fisheries

Late 20th century hottest in over 1000 years

From ABC News in Science, 22 April 2013: Average temperatures around the world in the last thirty years of the 20th century were higher than any other time in nearly 1400 years. That’s the conclusion of the first climate reconstruction to examine global climate change from a regional perspective by an international network of climatologists Continue reading Late 20th century hottest in over 1000 years
