The morning after a sweltering summer night, you’ve tossed and turned, sweated in your sheets, many may experience a rude awakening.
You know the feeling, you wake up feeling groggy, tired, irritable, almost like you have a hangover.
In Australia temperatures like last week’s heatwave – which saw suburbs stay at around 30 degrees Celsius overnight – and with hot days expected throughout the southern summer, sleep disruption is going to be a regular pain in the neck.
While the body’s core temperature generally hovers steadily around 37C, there is a potential for it to rise and develop into a fever if the surface temperature cannot be cooled and a room remains hot :: Read the full article »»»»

Ice baths are not as effective as an active warm down in soothing athletes’ muscles, Queensland researchers have found.
The researchers have thrown cold water on the use of ice baths to soothe the overworked muscles of athletes.
According to conventional thinking, ice baths reduce inflammation and damage. however a joint study by the University of Queensland and Queensland University of Technology has found an active warm down is more effective in building muscle mass and strength.
The University of Queensland’s School of Human Movement’s Dr Llion Roberts tracked the progress of 21 men who did strength training two days a week for three months.
Half of them did an active warm down and the rest had a 10 minute ice bath at 10 degrees :: Read the full article »»»»

Medical and engineering specialists say they are on the cusp of a breakthrough after successfully transplanting a bionic heart into a sheep.
The bionic heart was designed by Brisbane engineer Dr Daniel Timms in 2001 while he was studying at the Queensland University of Technology.
It contains a spinning disc with small blades on each side that pump blood around the body and lungs, without a traditional pulse.
The bionic heart can last at least 10 years and could help bridge the gap between patients requiring heart transplants and the number of donor hearts available.
The team, made up of Queensland and international researchers, said the device was a significant advance on other designs that were large, prone to wear, or could only pump on the left or right side.
It is expected to be ready for human trials within three years :: Read the full article »»»»

Researchers from the University of Adelaide say they’ve unraveled a key mechanism that may explain how obesity can be passed from mother to child, the discovery may also provide clarity into why obese women find it so difficult to fall pregnant.
According to their study, obese mothers ‘transmit’ metabolic problems to their offspring through changes to the mitochondria in their eggs, long before conception has taken place.
The researchers were able to reverse this damage in eggs of obese mice using drugs that reduce cellular stress.
They say their findings, published today in Development, may point towards future therapies to help obese women overcome fertility issues and prevent multigenerational health problems related to obesity :: Read the full article »»»»

Autism experts are calling for changes in diagnostic testing, saying the current approach is failing to identify the true number of females with the disorder.
They say a massive imbalance in the number of autism diagnoses between the sexes could be attributed to more subtle symptoms in females that are either dismissed by clinicians, or undetected by current testing, which focuses on signs associated with male behaviour.
The challenge in diagnosing girls with autism is a focus of Dr Ernsperger, who is speaking at a conference in Melbourne.
She believes the diagnostic questionnaires doctors use for autism focus mainly on the male characteristics of the disorder and are yet to be adapted for girls :: Read the full article »»»»
