Science Fact or Fiction Survey Confuddles Australians

Posted: July 16th, 2013 | Author: | Filed under: Science, Science News | Tags: , , , , , | Comments Off on Science Fact or Fiction Survey Confuddles Australians

Science Fact or Fiction Survey Confuddles AustraliansMore than 40 percent of Australians don’t know how long it takes the Earth to travel around the sun, according to a new survey, which also dug-up that nearly 30 percent of Australians didn’t know if humans lived at the same time as dinosaurs.

The Australian Academy of Science surveyed more than 1,500 people, asking them very basic scientific questions.

The survey is a repeat of a 2010 questionnaire, asking the same basic questions, it seems we’ve slowed our thinking – as a nation – way back in 2010 more than 70 percent knew that the earth took a year to travel around the sun.

The surveys author says it’s a wake-up call, he’s also worried that our knowledge of basic science might devolve even further, blaming popular culture and an insufficient school curriculum. We’re not alone however, the US seems to suffer similar symptoms  :: Read the full article »»»»


Australian Researchers Push Magnesium Sulphate as Cerebral Palsy Prevention

Posted: March 24th, 2012 | Author: | Filed under: Medical Research, Science | Tags: , , , , , | Comments Off on Australian Researchers Push Magnesium Sulphate as Cerebral Palsy Prevention

Australian Researchers Push Magnesium Sulphate as Cerebral Palsy Prevention BabiesThe risk of premature babies developing cerebral palsy is cut by a third if the mother is given magnesium sulphate immediately before birth, new research shows. So far it’s only been proven to work in babies born before 30 weeks, however, advocates of the research are saying that this new approach could prevent up to 150 babies a year from developing the chronic life-long condition.

Doctors are hailing the development as the biggest breakthrough in preventing the debilitating condition in 50 years, despite the fact it is not yet being routinely used in hospitals. The benefits of magnesium sulphate had been observed for a while, but obstetrics Professor Caroline Crowther says it was a large study in Australia and New Zealand in 2003 that gave compelling evidence. Read the full article »»»»


Researchers Reveal How a Single Gene Mutation Leads to Uncontrolled Obesity

Posted: March 20th, 2012 | Author: | Filed under: Medical Research, Science, Science News | Tags: , , , | Comments Off on Researchers Reveal How a Single Gene Mutation Leads to Uncontrolled Obesity

The discovery offers clues about how to turn on brain sensitivity to leptin and insulin, hormones that turn off appetite.

Researchers Reveal How a Single Gene Mutation Leads to Uncontrolled ObesityResearchers at Georgetown University Medical Center have revealed how a mutation in a single gene is responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain. What results is obesity caused by a voracious appetite.
Their study, published March 18th on Nature Medicine‘s website, suggests there might be a way to stimulate expression of that gene to treat obesity caused by uncontrolled eating.

The research team specifically found that a mutation in the brain-derived neurotrophic factor (Bdnf) gene in mice does not allow brain neurons to effectively pass leptin and insulin chemical signals through the brain. In humans, these hormones, which are released in the body after a person eats, are designed to “tell” the body to stop eating. But if the signals fail to reach correct locations in the hypothalamus, the area in the brain that signals satiety, eating continues. Read the full article »»»»


New Study Says Climate Obsessives Swayed By Media

Posted: March 14th, 2012 | Author: | Filed under: Medical Research, Science, Science News | Tags: , , , , | Comments Off on New Study Says Climate Obsessives Swayed By Media

Cankler Science News - New Study Says Obsessives Swayed By MediaA new published study has highlighted how the media influences opinion on emotive issues. The study undertaken by the University of Sydney was carried out to investigate whether climate change had any impact on the nature of the obsessions or compulsions experienced by sufferers of Obsessive Compulsive Disorder – OCD – The study takes reference from a 1994 study which found that some children developed obsessive thoughts about Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome – HIV/Aids – once media reports on the virus became common place.

We suggest that mental health professionals need to be aware of, and assess for the presence of such concerns” the study recommended.

This latest study has found that many patients suffering with OCD are worrying about the effects of climate change and global warming. Dr Mairwen Jones and her co-authors looked at 50 patients attending an anxiety disorders clinic. They found one-third of the patients had anxiety about the effects of climate change. The most common concerns were wasting water, gas and electricity, often leading to an obsessive checking to make sure utilities and appliances were switched off. Read the full article »»»»


HEALTH: Simply Standing Up From Desks Helps Avoid Diabetes

Posted: February 29th, 2012 | Author: | Filed under: Medical Research, Science | Tags: , , | Comments Off on HEALTH: Simply Standing Up From Desks Helps Avoid Diabetes

Diabetes Blue CircleResearch has revealed that interrupting sitting time with short bouts of light exercise can lower glucose and insulin levels by as much as 30 per cent, helping people avoid diabetes. The research was published online today in Diabetes Care, a publication of the American Diabetes Association. Associate Professor David Dunstan, from the Baker IDI Heart and Diabetes Institute, was the study’s lead researcher.

“What this study is showing is that people who sit for long periods, like office workers and call centre staff and drivers, could improve their health by simply breaking up their sitting time with frequent activity breaks,” Dunstan said. ”Inside this study we used breaks every 20 minutes, just for two-minute activity bouts, and showed that it was, it substantially improved the body’s response to a glucose challenge.”

Sixty per cent of Australians are either overweight or obese with the risk of developing diabetes. Professor Dunstan says people who work sitting at their desks should stand up at least every every 30 minutes. Read the full article »»»»
