Researchers develop advanced model to improve safety of next-generation reactors

When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at Fukushima-Daiichi automatically shut down, as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown,...

Pandemic paleo: A wayward skull, at-home fossil analyses, a first for Antarctic amphibians

Researchers have discovered the first fossil evidence of an ancient amphibian, Micropholis stowi, from Antarctica. Micropholis lived in the Early Triassic, shortly after Earth's largest mass extinction. It was previously known only from fossils in South Africa, and its presence in Antarctica has implications for how amphibians adapted to high-latitude regions in this dynamic period of Earth's...

Water treatment: Removing hormones with sunlight

Micropollutants such as steroid hormones contaminate drinking water worldwide. Until now, easily scalable water treatment technologies that remove them efficiently and sustainably have been lacking. Scientists have developed a new chemical process for removing hormones. It takes advantage of the mechanisms of photocatalysis and transforms the pollutants into potentially safe oxidation products.

Gene that causes canine hereditary deafness in puppies

Researchers have been the first to determine the cause for the nonsyndromic early-onset hereditary canine hearing loss in Rottweilers. The gene defect was identified in a gene relevant to the sense of hearing. The study can also promote the understanding of mechanisms of hearing loss in human.

In utero exposure to tiny air pollution particles is linked to asthma in preschoolers

Women who were highly exposed to ultra-fine particles in air pollution during their pregnancy were more likely to have children who developed asthma, according to a new study. This is the first time asthma has been linked with prenatal exposure to this type of air pollution, which is named for its tiny size and which is not regulated or routinely monitored in the United States.
