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.

SAN DIEGO -- In roughly one-third of pancreatic cancer patients, tumors have grown around the pancreas to encompass critical blood vessels. Conventional wisdom has long held that surgery to remove the tumors is rarely an option, and life expectancies are usually measured in months. Mayo Clinic, teaming oncologists, gastrointestinal and vascular surgeons and others, is finding that many of these patients actually are candidates for surgery. Mayo has been fine-tuning a protocol to treat them, and in two studies, found survival now stretching into years.

The findings were presented at the Pancreas Club and Society for Surgery of the Alimentary Tract annual meetings in San Diego.
