An aerogel material developed at MIT can generate heat of more than 200 degrees Celsius from sunlight, without the need for mirrors or vacuum tubes.
The inability of long-rooted trees to reach their subsurface water supply in the Sierra Nevada mountain range led to widespread forest die-offs following the drought of 2012-2015. A new study from UC Irvine and UC Merced scientists provides a better understanding of the climatic and biological mechanisms in play.
University of Otago scientists are part of an international research collaboration which has made an important discovery in the quest to lower global agricultural methane emissions.
Bark beetles are currently responsible for killing an unprecedented number of trees in forests across Europe and North America. Why the beetle populations first explode to decline naturally after a few years is largely unknown. Researchers are therefore urging to step up research into the dynamics of bark beetle populations. They believe that more needs to be done also in view of climate change.
Lifestyle changes can reduce our greenhouse gas emissions and help protect nature. While some actions offer great potential, some aren't as effective as we think and may even require more land and water, such as shifting to renewable energy.
A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have risen out of the sea much earlier than previously thought but were destroyed, leaving little trace.
The best way to protect corals threatened by climate change is to conserve a wide range of their habitats, according to a study in Nature Climate Change. The finding likely applies to conservation efforts for many other species in the ocean and on land, including trees and birds.
To meet internationally agreed-upon climate targets, the world's industrial nations will need to retire fossil fuel-burning energy infrastructure ahead of schedule, according to a new study in Nature from the University of California, Irvine and other institutions.
The Powering Past Coal Alliance, or PPCA, is a coalition of 30 countries and 22 cities and states, that aims to phase out unabated coal power. But analysis led by Chalmers University of Technology, Sweden, shows that members mainly pledge to close older plants near the end of their lifetimes, resulting in limited emissions reductions.
On a working wind farm, Stanford researchers have shown that angling turbines slightly away from the wind can boost energy produced overall and even out the otherwise variable supply.
