In the Canadian Arctic, a mystery has troubled scientists and local communities for decades: Why do marine animals in the western Arctic have higher mercury levels than those in the east?

It’s 5am as we head out onto the outermost pier,  where our trusty vessel awaits. Fog clings to the surface of the water as harbour seals play in the marina’s kelp beds below.

Researchers found that when water temperatures heat up for corals, fish ‘tempers’ cool down, providing the first clear evidence of coral bleaching serving as a trigger for rapid change in reef fish behaviour. 

Hurricane Willa is a major hurricane threatening western Mexico. Forecasters were able to see the rate of rainfall occurring within the powerful storm when the Global Precipitation Measurement mission or GPM’s core satellite passed overhead and provided that data.

Asian elephants demonstrate numeric ability which is closer to that observed in humans rather than in other animals. This is according to lead author Naoko Irie of SOKENDAI (The Graduate University for Advanced Studies) in Japan. In a study published in the Springer-branded Journal of Ethology, Irie and her colleagues found that an Asian elephants' sense of numbers is not affected by distance, magnitude or ratios of presented numerosities, and therefore provides initial experimental evidence that non-human animals have cognitive characteristics similar to human counting. 

Hurricanes Florence and Michael in the U.S. and Super Typhoon Mangkhut in the Philippines have shown the widespread and harmful impact of weather extremes on both ecosystems and built communities, with flash floods causing more deaths, as well as property and agriculture losses than from any other severe weather-related hazards. These losses have been increasing over the past 50 years and have exceeded $30 billion per year in the past decade. Globally, almost one billion people now live in floodplains, raising their exposure to river flooding from extreme weather events and underscoring the urgency in understanding and predicting these events. 

It’s called ArcCI (or Arctic CyberInfrastructure) and promises to combine the thousands of images that have been taken along the years of the Arctic Ocean into one global database that will help scientists and the world see the physical changes occurring in the region including ice loss. The hope is that this web-based repository will allow researchers to spend more time analyzing information rather than just collecting and processing data.

Treatment with the cyclin dependent kinase (CDK) 4/6 inhibitor palbociclib achieves a clinically meaningful improvement in overall survival in patients with hormone receptor positive (HR+) human epidermal growth factor receptor-2 negative (HER2-) advanced breast cancer that has relapsed or progressed on hormonal therapy, according to the final analysis of overall survival results from the PALOMA-3 study reported at ESMO 2018 (1).

A new type of blow fly spotted in Indiana points to shifting species populations due to climate change. Researchers at IUPUI have observed the first evidence of Lucilia cuprina in Indiana, an insect previously known to populate southern states from Virginia to California.

Adding highly refined fiber to processed foods could have negative effects on human health, such as promoting liver cancer, according to a new study by researchers at Georgia State University and the University of Toledo.
