Early Squirrel Gets the Real Estate, University of Guelph Study Finds

Those young squirrels now scampering around your neighbourhood were born in this year’s earliest litters and are more likely to survive than squirrels born later and still curled up in their nests, according to a new University of Guelph study.That’s because when it comes to survival in the squirrel world, the first out of the nest is best, said David Fisher, a post-doctoral researcher and lead author of the study conducted on squirrels in Yukon.

Isotopes with ocean circulation information

The Thorium-230 isotope in the marine sediment is used for paleo researchers to calibrate and normalize particle fluxes of past times. The isotope is present both in the water column and in the ocean sediments, the latter being the item for marine paleo geologists to examine.

NASA Sees Tropical Cyclone Ernie Intensify

The storm formerly known as tropical cyclone 15S, now called Tropical Cyclone Ernie continued to strengthen as NASA's Aqua satellite captured a visible image that showed the storm developed an eye.

Record New Renewable Power Capacity Added at Lower Cost

As the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 per cent lower than the previous year, according to new research published today by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance.Global Trends in Renewable Energy Investment 2017 finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8 per cent from the 127.5 gigawatts added the year before. The added generating capacity roughly equals that of the world's 16 largest existing power producing facilities combined.

Methane Levels Have Increased in Marcellus Shale Region Despite a Dip in Well Installation

Despite a slow down in the number of new natural gas wells in the Marcellus Shale region of Northeast Pennsylvania, new research led by Drexel University finds that atmospheric methane levels in the area are still increasing. Measurements of methane and other air pollutants taken three years apart in the rural areas of Pennsylvania that have been the target of natural gas development over the last decade, revealed a substantial increase from 2012 to 2015.
