Discovery adapts natural membrane to make hydrogen fuel from water



Posted: 10 Jan 2019 01:46 PM PST


Scientists have combined two membrane-bound protein complexes to perform a complete conversion of water molecules to hydrogen and oxygen.


Far-ranging fin whales find year-round residence in Gulf of California



Posted: 10 Jan 2019 01:09 PM PST


Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round -- an unusual circumstance for a whale species known to migrate across ocean basins.


For these birds, climate change spells a rise in fatal conflicts

Researchers have found yet another way in which climate change has been detrimental to migrating birds. As European winters have become warmer, pied flycatchers traveling from Africa to reach breeding grounds in the Netherlands are arriving to find that resident great tits have already claimed nesting sites for the season. As a result, the number of flycatchers killed in great tit nests has risen dramatically.


Oceans are warming even faster than previously thought



Posted: 10 Jan 2019 11:18 AM PST


Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or 'hiatus' in global warming over the past 15 years were unfounded.


Termites mitigate effects of drought in Tropical Rainforest



Posted: 10 Jan 2019 11:17 AM PST


Termites are commonly regarded as one of the most destructive insect pests, yet its unknown side was recently revealed by a major new study. Researchers have discovered that termites actually help mitigate against the effects of drought in tropical rain forests.


A new way to measure solar panel degradation



Posted: 10 Jan 2019 11:17 AM PST


How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.


Social and environmental costs of hydropower are underestimated, study shows



Posted: 10 Jan 2019 11:17 AM PST


Study shows that deforestation, loss of biodiversity and economic damage done to communities living near dams have not been factored into the cost of these projects. Large dams also ignore the effects of climate change.


Fish farmers of the Caribbean



Posted: 10 Jan 2019 11:17 AM PST


There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will only further increase the need for animal protein, one of the most resource-intensive types of food to produce.


Racial inequality in the deployment of rooftop solar energy in the United States, study finds



Posted: 10 Jan 2019 11:17 AM PST


Fewer rooftop solar photovoltaics installations exist in African-American and Hispanic-dominant neighborhoods than in white-dominant neighborhoods, even when controlling for household income and home ownership, according to a new study.


Solving the ancient mysteries of Easter Island



Posted: 10 Jan 2019 11:17 AM PST


The ancient people of Rapa Nui (Easter Island, Chile) built their famous ahu monuments near coastal freshwater sources, according to a team of researchers.


New materials could help improve the performance of perovskite solar cells



Posted: 10 Jan 2019 11:16 AM PST


New research could lead to the design of new materials to help improve the performance of perovskite solar cells (PSCs).


New computer modeling approach could improve understanding of megathrust earthquakes



Posted: 10 Jan 2019 07:14 AM PST


Years before the devastating Tohoku earthquake struck the coast of Japan in 2011, the Earth's crust near the site of the quake was starting to stir. Researchers are using computer models to investigate if tiny tremors detected near this site could be connected to the disaster itself.


Murky water keeps fish on edge



Posted: 10 Jan 2019 06:10 AM PST


Fish become anxious and more cautious when water quality is degraded by sediment, an effect that could stunt their growth and damage their health.


Geoscientists reconstruct 'eye-opening' 900-year Northeastern U.S. climate record



Posted: 09 Jan 2019 08:48 AM PST


Deploying a new technique for the first time in the region, geoscientists have reconstructed the longest and highest-resolution climate record for the Northeastern United States, which reveals previously undetected past temperature cycles and extends the record 900 years into the past, well beyond the previous early date of 1850.
