Well-trained cadaver dogs can be remarkably adept at discerning the smell of human remains from those of animals. Mimicking these canines' abilities in an artificial nose would be a huge help in disasters when thousands of people go missing. So scientists are trying to figure out what precise odors distinguish a human corpse from an animal one, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Washington, DC - April 6, 2016 - Vibrio parahaemolyticus caused an outbreak of food poisoning in Maryland in 2010. The pathogen strain sequenced from patients proved to be the same strain as one of those found in raw oysters from local restaurants, strong evidence that the oysters were the source of the illness. That particular strain of V. parahaemolyticus was not local, but was traced to Asia. The research is published March 18 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

When large-scale economic struggles hit a region, a country, or even a continent, the explanations tend to be big in nature as well.

Macroeconomists -- who study large economic phenomena -- often look for sweeping explanations of what has gone wrong, such as declines in productivity, consumer demand, or investor confidence, or significant changes in monetary policy.

But what if large-scale economic slumps can be traced to declines in relatively narrow industrial sectors? A newly published study co-authored by an MIT economist provides evidence that economic problems may often have smaller points of origin and then spread as part of a network effect.

Scientists at the Montreal Neurological Institute and Hospital at McGill University have made an important discovery about the human auditory system and how to study it, findings that could lead to better testing and diagnosis of hearing-related disorders.

The researchers detected frequency-following responses (FFR) coming from a part of the brain not previously known to emit them. FFRs are neural signals generated in the brain when people hear sounds.

Montreal, April 6, 2016 Montreal -- About one in 68 children in the United States has an autism spectrum disorder (ASD). Their parents consistently report greater stress levels, caregiving burden and depression than parents of typically developing children.

Chronic caregiving stress has also been associated with poorer physical health -- more pain, more disruptions from physical-health problems and lower overall health-related quality of life.

One powerful way to reduce their stress: social support. That's according to a new study published in Family Relations by researchers from Concordia University in Montreal.

And that support is essential as children -- and their parents -- age. It could also have important consequences for health costs.

Most traditional vaccines have safety and efficacy issues, whereas particulate vaccine delivery systems--which utilize nano- or micro-particulate carriers to protect and deliver antigens--are efficient, stable, include molecules to bolster immune responses, and minimize adverse reactions due to the use of biocompatible biomaterials. A new review summarizes the current status of research efforts to develop particulate vaccine delivery systems against bioterrorism agents and emerging infectious pathogens.

The available evidence indicates that particulate vaccine delivery systems should be strongly considered for public health preparedness and countermeasures against these threats.
