Ocean features and changes in the past are explored to anticipate future climate

(University of the Basque Country ) The Quaternary International journal has published a study by the UPV/EHU’s Department of Stratigraphy and Palaeontology describing, in detail, the climate changes taking place in the Bay of Biscay over the last 37,000 years. Specifically, it details these changes mainly through the study of foraminifera and ostracod species predominating in various climatic intervals. This palaeoceanographic study is part of a broader one covering the last 150,000 years.

Complex developmental patterns are under the control of surprisingly simple signals

(Princeton University) Princeton University researchers explored how patterns of protein activity direct fly embryonic development by using ‘optogenetic’ techniques to rapidly and precisely turn Ras/Erk signaling on and off. A paper published July 23 in Current Biology by Heath Johnson, Nareg Djabrayan, Stanislav Shvartsman and Jared Toettcher describes these findings.

Lahontan Cutthroat Trout thrive at Paiute’s Summit Lake in far northern Nevada

Summit Lake in remote northwest Nevada is home to the only self-sustaining, robust, lake population of Lahontan Cutthroat Trout, North America’s largest freshwater native trout species. Research to understand the reasons why this population continues to thrive, where others have not, will be used to protect the fish and its habitat – as well as to apply the knowledge to help restore other Nevada lakes that once had bountiful numbers of the iconic fish that historically reached 60 pounds.

When should you neuter your dog to avoid health risks?

A new, 10-year study by researchers at the University of California, Davis, examined 35 dog breeds and found vulnerability from neutering, and the age at which they are neutered, varies greatly depending on the breed.
