University of Adelaide researchers have identified a likely molecular pathway that causes a group of untreatable neurodegenerative diseases, including Huntington's disease and Lou Gehrig's disease. The group of about 20 diseases, which show overlapping symptoms that typically include nerve cell death, share a similar genetic mutation mechanism ‒ but how this form of mutation causes these diseases has remained a mystery. "Despite the genes for some of these diseases having been...

Dragonflies May Help Improve Robotic Vision Systems

[ Watch the Video: Dragonflies Hunt Food Like Humans ] April Flowers for redOrbit.com - Your Universe Online What do a dragonfly and a robot have in common? Nothing yet, but researchers at the University of Adelaide have discovered a novel and complex visual circuit in a dragonfly’s brain that might someday help to improve vision systems for robots. The underlying processes of insect vision have been the research subject for Dr Steven Wiederman and Associate Professor David...

University of Adelaide marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2. The researchers have found a combined effect on kelp forests from nutrient pollution and higher CO2, which could have a devastating impact on Australia's marine ecosystems. "When we manipulated CO2 and nutrient levels in an experimental marine ecosystem we found the effect of both of them together...

Medical diagnostic and security scanners with higher sensitivity could result from University of Adelaide research into detecting T-rays (terahertz waves). Published in the journal Advanced Optical Materials, the researchers describe a novel structure which traps terahertz waves in tiny (micro-scale) holes to produce much higher contrast imaging than currently possible. Terahertz waves, which are electromagnetic waves with frequencies between those used for mobile phone communications...

University of Adelaide researchers have developed a new nanomaterial that could help reduce carbon dioxide emissions from coal-fired power stations. The new nanomaterial, described in the Journal of the American Chemical Society, efficiently separates the greenhouse gas carbon dioxide from nitrogen, the other significant component of the waste gas released by coal-fired power stations. This would allow the carbon dioxide to be separated before being stored, rather than released to the...

Research from the University of Adelaide shows that iodized salt used in bread is not enough to provide healthy levels of iodine for pregnant women and their unborn children. The study-— led by researchers from the University's Robinson Institute — has prompted calls for pregnant women to keep taking iodine supplements. Iodine deficiency is recognized by the World Health Organization (WHO) as the most common preventable cause of brain damage in the world. "Iodine is an...

Australian Lake Relatively Untouched By Climate Change

University of Adelaide Researchers at the University of Adelaide have found that a lake on an island off the coast of Queensland, Australia, has been relatively untouched by changes in climate for the past 7000 years, and has so far also resisted the impact of humans. Blue Lake, one of the largest lakes on North Stradbroke Island, southeast of Brisbane, has been the focus of research examining the lake's response to environmental change over time. Researchers studied the lake's water...

A simpler and faster way of producing designer bacteria used in biotechnology processes has been developed by University of Adelaide researchers. The researchers have developed a new one-step bacterial genetic engineering process called 'clonetegration', published in the journal ACS Synthetic Biology. Led by Dr Keith Shearwin, in the University's School of Molecular and Biomedical Sciences, the research facilitates faster development of designer bacteria used in therapeutic drug...

The widespread introduction of a chicken pox vaccine in Australia in 2006 has prevented thousands of children from being hospitalized with severe chicken pox and saved lives, according to new research. In a national study of chicken pox admissions at four participating Australian children's hospitals, researchers found the number of children hospitalized with chicken pox or shingles had dropped by 68% since 2006. The research was led by Associate Professor Helen Marshall from the...

New research from the University of Adelaide will rewrite the textbooks on how an ovary is formed, as well as providing new insights into women's health and fertility. The study, now published in the journal PLOS ONE, also names a new type of cell that plays a key role in the development of ovaries and ovarian follicles, which are responsible for the production of eggs in women. The discovery is expected to prompt further studies around the world to better understand how ovaries and...
