Will Large Protected Areas Save the Oceans or Politicize Them?
How can we save the oceans? They cover two-thirds of the planet, but none are safe from fishing fleets, minerals prospectors, or the insidious influences of global warming and ocean acidification.
Study Examines Commercial Hybrid-Electric Aircraft, Reduced Carbon Emissions
Although we’re still a long way from commercial airplanes powered by a combination of fossil fuel and batteries, a recent feasibility study at the University of Illinois explored fuel/battery configurations and the energy lifecycle to learn the tradeoffs needed to yield the greatest reductions in carbon dioxide emissions.
Genetic Tagging May Unlock Nature’s Secrets and Help Conserve the World’s Wildlife
Tracking animals using DNA signatures are ideally suited to answer the pressing questions required to conserve the world’s wildlife, providing benefits over invasive methods such as ear tags and collars, according to a new study by University of Alberta biologists.
