Researchers discover new, abundant enzyme that helps bacteria infect animals
September 22, 2017 05:50 PM - University of Waterloo

Researchers have discovered a new class of enzymes in hundreds of bacterial species, including some that cause disease in humans and animals. The discovery provides new insights into how bacteria invade their hosts. The research appears this week in Nature Communications.

Asteroid that killed dinosaurs may have sped up bird evolution

Human activities could trigger an altered pattern of evolution similar to what occurred 66 million years ago, when a giant asteroid wiped out the dinosaurs, leaving birds as their only descendants. 

UMN researchers find recipe for forest restoration
September 22, 2017 01:47 PM - University of Minnesota

To find out what works best for reestablishing tropical dry forests, the researchers planted seedlings of 32 native tree species in degraded soil or degraded soil amended with sand, rice hulls, rice hull ash or hydrogel.

Scientists and Farmers Work Together to Wipe Out African Lovegrass

A partnership between QUT, the NSW Government and farmers could lead to the eventual eradication of the highly invasive African lovegrass which is threatening pastures and native grasslands Australia-wide.

Green Algae Could Hold Clues for Engineering Faster-Growing Crops
September 21, 2017 01:39 PM - Princeton University

Two new studies of green algae — the scourge of swimming pool owners and freshwater ponds — have revealed new insights into how these organisms siphon carbon dioxide from the air for use in photosynthesis, a key factor in their ability to grow so quickly. Understanding this process may someday help researchers improve the growth rate of crops such as wheat and rice.

When residents take charge of their rainforests, fewer trees die

When the government gives citizens a personal stake in forested land, trees don’t disappear as quickly and environmental harm slows down.

Protected Waters Foster Resurgence of West Coast Rockfish

West Coast rockfish species in deep collapse only 20 years ago have multiplied rapidly in large marine protected areas off Southern California, likely seeding surrounding waters with enough offspring to offer promise of renewed fishing, a new study has found.

New Study Pushes Back Deadline to Act to Limit Warming to 1.5 Degrees
September 20, 2017 03:40 PM - Yale Environment 360

A new study suggests that nations have a bit more time than previously thought if they want to cut greenhouse gas emissions and limit global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit). The research, published in the journal Nature Geoscience, finds that the world’s economies can emit an additional 700 billion tons of carbon dioxide before exceeding 1.5 degrees — more than twice previous estimates.

Fly away home? Ice age may have clipped bird migration
September 20, 2017 03:29 PM - University of Nebraska-Lincoln

The onset of the last ice age may have forced some bird species to abandon their northerly migrations for thousands of years, says new research led by a University of Nebraska-Lincoln ornithologist.
