(Press-News.org) An Australian study to determine the likelihood of school-aged children waking up to their home smoke alarm found that 78% of children slept through a smoke alarm sounding for 30 seconds. The outcomes of the study are published today in the journal Fire and Materials.
Home smoke detectors have been relied on since the 1960s, and have been known to save lives in domestic fires. The study's results show children are most at risk of not waking up to the sound of their home's smoke detector. Though related studies have been conducted in the past, the sample size used in this study has been the largest to date.
In order to gather data for the study, parents of 123 children (79 families) were asked to trigger their smoke alarm for 30 seconds after their child, or children, had been asleep for one to three hours. 60 boys and 63 girls were included in the study and the average age was 8.82 years. The group was split into two age groups so that the younger group would be prepubescent. This is because plasma melatonin levels drop with puberty onset and the melatonin hormone is known to be sleep-inducing. About 70% of the participants were aged from 5 - 10 years (87) and 30% from 11 - 15 years (36).
Volunteer parents reported whether or not their children woke using a research website, and the results showed that 78% of the children slept through the alarm. Of the small number of children who did wake up, only half recognized the sound as a smoke alarm, and half of those children knew they should evacuate. The data collected also showed that younger children (five to ten years old) were significantly more at risk, with 87% sleeping through the alarm, compared to 56% of 11-15 year olds.
"Parents should not rely on their children waking to the smoke alarm in the event of a fire and should not assume that they will immediately evacuate if they do wake up to a fire," says Dr. Dorothy Bruck, lead author of the study at Victoria University in Melbourne, Australia. "In summary, home safety plans should not assume children will wake up to an alarm. This data suggests fire safety training needs more emphasis on the need for children to evacuate the home in the event of an alarm sounding."

What Every California Driver Needs to Know about UM Insurance
2011-03-13
What is UM Insurance?
Uninsured motorist insurance, or UM or UMI, provides protection when you are in an accident with an uninsured driver. UM also provides benefits in cases when you are involved in a hit and run accident so long as the uninsured vehicle made physical contact with your car.
In addition to UM coverage, there also is UIM, or underinsured motorist, coverage. UIM provides benefits when you are in an accident with a driver who does not have enough insurance to cover all of your losses - which you are at risk of having happen any time you are in an accident ...
Nanoscale whiskers from sea creatures could grow human muscle tissue

Nanoscale whiskers from sea creatures could grow human muscle tissue
Minute whiskers of nanoscale dimensions taken from sea creatures could hold the key to creating working human muscle tissue, University of Manchester researchers have discovered.
Scientists have found that cellulose from tunicates, commonly known as sea squirts, can influence the behaviour of skeletal muscle cells in the laboratory.
These nanostructures are several thousand times smaller than muscle cells and are the smallest physical feature found to cause cell alignment.
Alignment is important ...
Finding shows potential way to protect neurons in Parkinson's, Alzheimer's, ALS
2011-03-13
SAN ANTONIO (March 11, 2011) — Cell biologists pondering the death of neurons — brain cells — said today that by eliminating one ingredient from the cellular machinery, they prolonged the life of neurons stressed by a pesticide chemical. The finding identifies a potential therapeutic target to slow changes that lead to neurodegenerative disorders such as Parkinson's and Alzheimer's diseases.
The researchers, from The University of Texas Health Science Center San Antonio, found that neurons lacking a substance called caspase-2 were better able to withstand pesticide-induced ...
Bruno Mars Pleads Guilty to Felony Cocaine Charge, Las Vegas Judge Hands Down Probation
2011-03-13
Bruno Mars became a forefront figure in the music industry the minute his popular songs like "Grenade" and "Just the Way You Are" hit the airwaves. But his honest and wholesome image soon became tainted when media outlets exposed his recent cocaine bust last September 2010 in a public restroom at the popular Las Vegas Hard Rock Hotel. Since then, not much has been disclosed about Mars' legal woes--until now.
The Associated Press reports that the singer recently accepted a plea deal. Mars, whose real name is Peter Hernandez, pled guilty last month to a felony cocaine ...

BOSTON/NEW YORK – March 11, 2011 –A study by Professor Stephan Meier, Assistant Professor, Management at Columbia Business School, and co-author Andreas Fuster, Ph.D. candidate, Harvard University Department of Economics, which was published in Management Science, an INFORMSR publication, found that while monetary incentives in the workplace, such as subsidies or bonuses, are regarded to be effective ways to encourage staff contributions, incentives can interfere in public and workplace environments dependent on informal norm enforcement. In the context of this study, informal ...
More molecules for tuberculosis
2011-03-13
Scientists are collaborating on a new international research project to identify antibiotics that can kill tuberculosis and fight resistant strains.
"We want to accelerate the discovery of new compounds that can be turned into effective drugs," said Professor Tony Maxwell from the John Innes Centre, a key player in "More Medicines for Tuberculosis", a new European research project.
Two billion people are currently infected with TB and three million die every year. TB causes more deaths than any other infectious disease. Rates are increasing, especially in sub-Saharan ...
Medical Value of Storing Cord Blood Is Disputed
2011-03-13
Each year, the Centers for Disease Control (CDC) numbers show that there are more than 4 million babies born. While most of the babies born each year are healthy infants, it is estimated that approximately 185,000 are born each year with health problems from genetic disorders such as spina bifida or Down syndrome; and another five to seven newborns per 1,000 experience birth injuries or birth trauma that can cause permanent damage, such as Erb's palsy or cerebral palsy.
Parents experience a significant amount of stress and anxiety in the course of pregnancy, childbirth ...
U of A researcher questions whether genius might be a result of hormonal influences
2011-03-13
A longstanding debate as to whether genius is a byproduct of good genes or good environment has an upstart challenger that may take the discussion in an entirely new direction. University of Alberta researcher Marty Mrazik says being bright may be due to an excess level of a natural hormone.
Mrazik, a professor in the Faculty of Education's educational psychology department, and a colleague from Rider University in the U.S., have published a paper in Roeper Review linking giftedness (having an IQ score of 130 or higher) to prenatal exposure of higher levels of testosterone. ...
Stem cells take cues from fluid in the brain
2011-03-13
Proteins in fluids bathing the brain are essential for building the brain, discover scientists in a report published March 10 in the journal Neuron. The finding promises to advance research related to neurological disease, cancer and stem cells.
Before now, the fluid surrounding the brain was generally considered to be a sort of salt-solution that simply maintained the brain's ionic balance. Recent reports of fluctuating proteins in the fluid suggested otherwise, however. And thus, a multi-institutional research teams at the Children's Hospital in Boston, led by Maria ...
Keys to long life
2011-03-13
RIVERSIDE, Calif. - Cheer up. Stop worrying. Don't work so hard.
Good advice for a long life? As it turns out, no. In a groundbreaking study of personality as a predictor of longevity, University of California, Riverside researchers found just the opposite.
"It's surprising just how often common assumptions – by both scientists and the media – are wrong," said Howard S. Friedman, distinguished professor of psychology who led the 20-year study.
Friedman and Leslie R. Martin , a 1996 UCR alumna (Ph.D.) and staff researchers, have published those findings in "The Longevity ...
