Montreal, May 25, 2016 -- Humans aren't much different from other animals. Just like Pavlov's dogs, we can become conditioned to associate environmental cues with rewards. Innocent enough when the sight of your sneakers makes you want to go for a run, but not necessarily so when the sight of the liquor store prompts you to want a drink.

Indeed, Pavlovian cues that predict alcohol can lead us toward addiction. And sometimes those cues can become desirable in and of themselves, as shown in a new study published in Frontiers in Behavioral Neuroscience by researchers from Concordia University in Montreal.

SAN FRANCISCO - May 25, 2016 - Researchers studying babies with a Zika virus-related birth defect say they have found previously unreported eye problems possibly linked to the virus that could result in severe visual impairment. In three Brazilian infants with microcephaly, the researchers observed retinal lesions, hemorrhaging and abnormal blood vessel development not noted before in relation to the virus. The findings are being published online today in Ophthalmology, journal of the American Academy of Ophthalmology.

Black carbon aerosols--particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way--are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting. Unfortunately, current simulation models, which combine global climate models with aerosol transport models, consistently underestimate the amount of these aerosols in the Arctic compared to actual measurements during the spring and winter seasons, making it difficult to accurately assess the impact of these substances on the climate.

There are better solutions to the "reproducibility crisis" in research, according to an editorial published today.

Should an academic institution refund its financial payment if the basic science or pre-clinical results prove to be irreproducible?

Such an "incentive-based approach" for improving data reproducibility was recently proposed by a senior executive at Merck, although the idea is said not to represent the company's position.

But in an editorial published by The BMJ today, Eric Topol, Director of Scripps Translational Science Institute in California, argues that there are better solutions to the "reproducibility crisis" in research.

A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts.

Prof. Stefan Doerr and Dr Cristina Santin from Swansea University's College of Science carried out detailed analysis of global and regional data on fire occurrence, severity and its impacts on society.

Their research, published in Philosophical Transactions of the Royal Society B, looked at charcoal records in sediments and isotope-ratio records in ice cores, to build up a picture of wildfire in the past.

Researchers from the University of Rochester suggest that children raised in poverty may have been mistakenly labeled as "maladapted" for what appears to be a lack of self-control. The new study finds that what looks like selfishness may actually be beneficial behavior that's based on a child's environmental context--that is to say, from being raised in a resource-poor environment.
