Sloth truly deserves its name, biologists say
Imagine a creature so slothful that it snacks off its own fur and budges only once a week for a bowel movement.
How birds got their wings: Fossil data show scaling of limbs altered as birds originated from dinosaurs
Birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans sometime around 150 million years ago. Recent findings from around the world show that many maniraptorans were very ...
New study finds charred forests increase snowmelt rate
(Phys.org) —When a major wildfire destroys a large forested area in the seasonal snow zone, snow tends to accumulate at a greater level in the burned area than in adjacent forests. But a new study found ...
Gravity waves and sunglint, lake superior
From the vantage point of the International Space Station, astronauts frequently observe atmospheric and surface phenomena in ways that are impossible to view from the ground. Two such phenomena—gravity ...
Brazilian team finds new porcupine species
A new species of tree-dwelling porcupine has been discovered in Brazil's Northeastern Atlantic Forest, one of the world's most threatened habitats, researchers said.
Drought does long-term damage to rainforest
Recent droughts in the Amazon rainforest have effects that persist long after the rains have returned, a new study has shown.
Scientific paper challenges assumptions about bark beetles' link to wildfires
Don't blame bark beetles for catastrophic wildfires such as the blaze that blackened more than 23,000 acres of Kittitas County in Washington state last summer, some scientists say.
Study finds severe climate jeopardizing Amazon forest
(Phys.org)—An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with ...

Researchers examining birds' control, behavioral processes as model for small, highly maneuverable aircraft
The Office of Naval Research (ONR) is looking at birds' perceptual and maneuvering abilities as inspiration for small unmanned aerial vehicle (UAV) autonomy.
Research finds autumn advantage for invasive plants in Eastern United States
Much like the fabled tortoise and the hare, the competition between native and invasive plants growing in deciduous forests in the Eastern United States is all about how the plants cross the finish line in autumn.
Scientists forecast forest carbon loss
For more than 30 years, scientists at the Harvard Forest have scaled towers into the forest canopy and measured the trunks of trees to track how much carbon is stored or lost from the woods each year. This treasure trove ...
NASA map sees Earth's trees in a new light
A NASA-led science team has created an accurate, high-resolution map of the height of Earth's forests. The map will help scientists better understand the role forests play in climate change and how their heights ...
