Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70 percent, in a new study conclusion that bodes well for airline economics and Earth’s environment.

The findings are the result of a cooperative international research program led by NASA and involving agencies from Germany and Canada, and are detailed in a study published in the journal Nature.

At University of Toronto Mississauga, a plastic tower sprouts produce including curly starbor kale, buttercrunch and collard greens.

Rising almost six feet off the ground and illuminated by high output fluorescent bulbs, the indoor farm wall grows plants hydroponically – with nutrient solution, instead of soil.

The National Science Foundation (NSF) has made a $5.6 million, five-year grant to establish a Long-Term Ecological Research (LTER) site along the northern Alaskan coast that will focus on the interactions between land and ocean that shape coastal ecosystems in the Arctic over different time scales.

Researchers at the Beaufort Sea Lagoons LTER site will study food webs, which support large-scale coastal fisheries and more than 150 species of migratory birds and waterfowl. Long-term changes along the northern Alaska coast have already affected the types of fish and other creatures that live in the lagoons, and are expected to continue to do so. The LTER research team will collaborate with members of local communities, including the Iñupiat, and with the U.S. Fish and Wildlife Service, which manages the Arctic National Wildlife Refuge.

Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.
