Hotter and drier conditions limit forest recovery from wildfires
Warmer and drier climate conditions in western U.S. forests are making it less likely that trees can regenerate after wildfires, according to new research published in the Proceedings of the National Academy of Sciences......»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time
The weathered UC Davis Marine Laboratory looms in thick fog on the edge of the ocean near Bodega Bay. Inside, an experiment is playing out that gives a badly-needed boost to Northern California's kelp forests—underwater cathedrals of green and gold.....»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»

Study examines effects of Atlantic circulation on the Amazon rainforest
The Amazon region is a global hotspot of biodiversity and plays a key role in the climate system because of its ability to store large amounts of carbon and its influence on the global water cycle. The rain forest is threatened, however, by climate c.....»»
Revealing the superconducting limit of twisted bilayer graphene
Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces numerous intriguing effects, notably superconductivity......»»
Nations gather for crunch climate talks in shadow of US vote
World leaders kick off UN climate talks next week, days after a knife edge US election that could send shockwaves through global efforts to limit dangerous warming......»»
215 million hectares of forest—an area bigger than Mexico—could grow back by itself, if we can just leave it alone
About 215 million hectares of land—an area bigger than Mexico—could be reforested naturally and without costly manual planting, our new research shows......»»
Green shoots spring from ashes in Brazil"s fire-resistant savanna
The huge wildfires that ripped through Brazil recently did not spare its vast tropical savanna, but green shoots are already emerging from the ashes there, proof of the vast grasslands' rare gift for fire resistance......»»
