A collaborative study led by scientists from the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) has revealed the mechanical forces that drive epithelial wound healing in the absence of cell supporting environment. This research was published in Nature Communications in January 2015.
Skin not only provides an essential protective barrier against foreign materials and pathogens, but it also helps the body retain various fluids and electrolytes. When this barrier is damaged, the consequences can be devastating. Ulcers, bleeding and bacterial infections may result and the chances of these occurring increases the longer wounds remain open.

A barrier to increased human papillomavirus (HPV) vaccination has been the concern that it may promote unsafe sexual activity, but a new study of adolescent girls finds that HPV vaccination was not associated with increases in sexually transmitted infections (STIs).

Both weight gain and weight loss in older (postmenopausal) women are associated with increased incidence of fracture, but at different anatomical sites, finds a study published in The BMJ this week.
The findings also challenge the traditional view that weight gain protects against fractures.
The influence of body weight on the risk of fracture is complex. Low body weight is a well recognised risk factor for fracture, but obesity also increases the risk of fracture at some sites. How fracture patterns differ after intentional and unintentional weight loss in postmenopausal women is also unknown.

A new research project looked at how to create various non-spherical particles. 
Non-spherical particles have a great deal of potential uses in industry because associated with their different shapes are properties such as large surface areas, high packing densities and unique responses to external electric and magnetic fields. Such properties can lend themselves to applications ranging from food processing, consumer goods such as cosmetics, absorbents, and drug delivery systems.

We've had 50 years of very-expensive, government-mandated penalties against cigarette companies that have funded programs to reduce cigarette smoking - anything that does so should be welcomed. Yet that hasn't been the case for e-cigarettes. While patches have been adored with only modest success in lowering smoking rates - willpower remains the determining factor in smoking cessation - e-cigarettes are being assaulted in a culture war almost as powerful as smoking itself.At a meeting in San Jose of an organization named AAAS, experts from Germany, New Zealand, South Africa, the UK and USA debated whether electronic cigarettes are just another addiction or a public health opportunity?.

Children obtain better and more age-appropriate sleep in the presence of household rules and regular sleep-wake routines, according to sleep researchers.
The researchers found that well-established rules for getting good sleep, such as limited caffeine and a regular bedtime, led to sufficient sleep quantity and adequate sleep quality. In contrast, when parents and children had electronic devices on in the bedroom after bedtime, sleep deficiency was more likely.
Reducing the encroachment of technology and media into sleep time and supporting well-known sleep hygiene principles should be a focus of public health intervention goals for sleep health, the researchers said.

People 60 or older, especially minorities and women, have a lower risk of stroke if the top number (systolic) in their blood pressure is below 140 millimeters of mercury (mm Hg), according to a study presented at the American Stroke Association's International Stroke Conference 2015.
A report published in JAMA in 2014, advised doctors to aim for blood pressure readings of less than 150/90 mm Hg when treating patients 60 or older who do not have diabetes or chronic kidney disease. That raised the standard for systolic blood pressure, by 10 points from previous guidance, stirring controversy among healthcare providers, agencies and professional groups.

Some of the coldest air of the 2014-2015 winter season is settling over the eastern two-thirds of the U.S., an Arctic air mass that brought wind chills from below zero to the single numbers from the Midwest to the Mid-Atlantic. It is certainly cold on the surface, but infrared NASA satellite imagery revealed even colder temperatures in cloud tops associated with the air mass.

Evolution starts species off on different paths and even if they arrived in one spot from common descent in the past, they can't reproduce. So in modern times an elephant is not hybridizing with a manatee, or a human with a lemur. Tree frogs...well, yes, but who can explain tree frogs? That did happen, two species were able to interbreed after
34 million years, and sunfish who hybridized after nearly 40 million years.

There may be a new explanation for why fad diets tend to cluster in pockets - and it may help companies spend their marketing money a little smarter also.

A 10-year retrospective study of 383 children is the first to examine the prevalence of positive drug screens in pediatric patients undergoing  multiple sleep latency test (MSLT)
for narcolepsy. The results in Journal of Clinical Sleep Medicine showed that 43 percent of children with urine drug screens positive for marijuana actually had test results consistent with narcolepsy or abnormal REM sleep patterns. No child younger than 13 years of age had a positive urine drug screen. The data showed that males were more likely to have a positive urine drug screen and MSLT findings consistent with narcolepsy.  

Suppose we we tell you everything quantum mechanics can tell you about a quantum particle; what do you really know? Unfortunately, you still cannot predict with certainty the outcome of a simple experiment to measure its state. All quantum mechanics can offer are statistical probabilities for possible results.This indeterminacy is not a defect, it's a defining feature of its undefined nature. The particle's state is not merely unknown, but truly undefined before it is measured. The act of measurement itself forces the particle to collapse to a definite state.
