DNA uncovers 1 of the world's rarest birds

DNA uncovers 1 of the world's rarest birds
2010-11-24
(Press-News.org) A team of Australian researchers involving DNA experts from the University of Adelaide has identified a new, critically endangered species of ground parrot in Western Australia.

The team, led by Australian Wildlife Conservancy's Dr Stephen Murphy, used DNA from museum specimens up to 160 years old to reveal that populations of ground parrots in eastern and western Australia are highly distinct from each other and that the western populations should be recognized as a new species, Pezoporus flaviventris.

"The discovery has major conservation implications," said Dr Murphy. "The Western Ground parrot has declined rapidly in the last 20 years, there are now only about 110 birds surviving in the wild and most of these are confined to a single national park. It is now one of the world's rarest birds."

WA Department of Environment and Conservation's Dr Allan Burbidge said: "A single wildfire through the national park or an influx of introduced predators, such as cats, could rapidly push the species to extinction. There is now an urgent need to prevent further population declines and to establish insurance populations into parts of the former range."

"Our findings demonstrate that museum collections, some going back more than 150 years, continue to be relevant and can provide critical information for understanding and conserving the world's biodiversity into the future," said team member Dr Jeremy Austin, Deputy Director of the Australian Centre for Ancient DNA at the University of Adelaide.

Director of CSIRO's Australian National Wildlife Collection, Dr Leo Joseph, said: "Even after 200 years of study, we are still recognizing new species of birds in Australia. This finding highlights the need for further research on Australia's unique, and sometimes cryptic, biodiversity."



INFORMATION:

The team's findings have been published this month in the international conservation research journal Conservation Genetics.

Tobacco: Out of sight, out of mind?

2010-11-24
Putting tobacco out of sight in shops can change the attitude of young people to smoking, while not hitting retailers in the pocket, researchers at The University of Nottingham have discovered. Academics from the University's UK Centre for Tobacco Control Studies looked at the effect of the removal of tobacco displays in the Republic of Ireland, ahead of similar legislation which is due to come into force in the UK. The findings are published today in the journal Tobacco Control. In one study the research team found that the number of teenagers who recalled tobacco ...

Dietitians play essential role in effective management of Type 1 and Type 2 diabetes in adults

2010-11-24
St. Louis, MO, 23 November, 2010 – Proper nutrition therapy is essential for the successful management of type 1 and type 2 diabetes and registered dietitians (RDs) can play a key role as part of the health care team. An article in the December issue of the Journal of the American Dietetic Association reviews the evidence and nutrition practice recommendations presented in the American Dietetic Association Nutrition Practice Guidelines for Type 1 and Type 2 Diabetes in Adults. This complete and systematic review presents 29 key nutrition practice guidelines in order to ...

Daily dose of HIV drug reduces risk of HIV infection

2010-11-24
A daily dose of an oral antiretroviral drug, currently approved to treat HIV infection, reduced the risk of acquiring HIV infection by 43.8 percent among men who have sex with men. The findings, a major advance in HIV prevention research, come from a large international clinical trial published online Nov. 23 by the New England Journal of Medicine. The study, titled "Chemoprophylaxis for HIV Prevention in Men," found even higher rates of effectiveness, up to 72.8 percent, among those participants who adhered most closely to the daily drug regimen. "We now have strong ...

Extending the life of oil reserves

2010-11-24
A research team led by the University of Bristol has used STFC's ISIS Neutron Source to come up with a new way to treat carbon dioxide (CO2), so that it can be used in efficient and environmentally friendly methods for extracting oil. These new CO2 soluble additives can also be used to reduce the environmental damage caused by every day industrial processes such as food processing and the manufacture of electronics. The results of this work are published in the journal Langmuir. The researchers have developed a soap-like additive for CO2 that turns it into a viable solvent ...

Use of HIV medications reduces risk of HIV infection in uninfected people

2010-11-24
(San Francisco, CA) – In a finding with the potential to fundamentally change strategies to slow the global HIV epidemic, a new study called iPrEx shows that individuals at high risk for HIV infection who took a single daily tablet containing two widely used HIV medications, emtricitabine and tenofovir (FTC/TDF), experienced an average of 43.8% fewer HIV infections than those who received a placebo pill (95% CI 15.4 to 62.6%; P=0.005). The study, reported in the New England Journal of Medicine, is the first evidence that this new HIV prevention method, called pre-exposure ...

Discovery halts breast cancer stem cells

2010-11-24
BOSTON (Nov. 23, 2010) —Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development. Disrupting the pathway, researchers were able to halt the expansion of breast CSCs, a finding that suggests a new drug therapy target. The study, done in mice, is published in the Proceedings of the National Academy of Sciences (PNAS) Early Edition this week. "A critical aspect of our work was to discover that estrogen could ...

CONRAD applauds results of global iPrEx study

2010-11-24
ARLINGTON, VA-- NOVEMBER 23, 2010 - - CONRAD is pleased to join in congratulating the Global iPrEx study team for their successful trial of oral tenofovir (TDF) with emtricitabine (FTC) for HIV prevention. Results of the National Institutes of Health (NIH) sponsored study were announced today in the New England Journal of Medicine. Daily use of the widely used antiretroviral combination pill was found to be an average of 44% effective in reducing risk of HIV infection in men who have sex with men (MSM), a historically high risk population. Among participants who took ...

For your teeth, Thanksgiving dinner is a real food fight

2010-11-24
If you're lucky, it will all be kisses and hugs around the Thanksgiving dinner table, with friends and family near and dear gathered about, and puppies gathered around your feet waiting for table scraps. But peace won't reign within the confines of the oral cavity, where Streptococcus mutans and other harmful bacteria will await their own holiday feast. Your meal will enable S. mutans to launch one of its biggest assaults of the year on your tooth enamel. New work by dental researchers at the University of Rochester Medical Center brings both good and bad news. While ...

Developing countries often outsource deforestation, study finds

Developing countries often outsource deforestation, study finds
2010-11-24
In many developing countries, forest restoration at home has led to deforestation abroad, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). The authors say their findings could have significant implications for ongoing efforts to protect the world's remaining forests, which are disappearing at an annual rate of more than 32 million acres – an area roughly the size of England. "Reducing deforestation is an international priority, given its impacts on carbon emissions and biodiversity," said study co-author Eric Lambin of Stanford ...

Koalas as picky leaf-eaters, ancient insects in warm climates and California's forest fires

2010-11-24
Ask the Eucalyptus connoisseurs Koalas may be the pickiest marsupials around: They evolved to feed almost exclusively on the leaves of Eucalyptus trees, and they are highly selective when it comes to which species and even which individual trees they visit. When the furry leaf-eater settles on a particular tree, it relies on a number of factors, including taste, to make its selection. In a study published in the November issue of Ecology, a journal of the Ecological Society of America (ESA), researchers used koala feeding preferences to design a new method that could help ...
