Utility-scale Solar Installations Can Avoid Using Farmland, Study Says
Across the U.S., the energy and agricultural industries are battling it out over whether to place solar panels or crops on large stretches of flat, sunny land. Now, a new study finds that developing solar energy arrays on alternative sites like buildings, lakes, and contaminated land would allow California to meet its 2025 electricity demands without sacrificing…

Drinking coffee may lower risk of early death from colorectal cancer
People with colorectal cancer (CRC) who drank at least four cups of coffee per day after their diagnosis had a significantly lower risk of early death—from either their cancer or any cause—than those who didn’t drink coffee, according to a new study from Harvard T.H. Chan School of Public Health.

Cleaner air, longer lives
The air we breathe contains particulate matter from a range of natural and human-related sources. Particulate matter is responsible for thousands of premature deaths in the United States each year, but legislation from the U.S. Environmental Protection Agency (EPA) is credited with significantly decreasing this number, as well as the amount of particulate matter in…

In Mussels Across the Globe, Evidence of the Spread of Plastic Pollution
Scientists have discovered tiny bits of plastic in mussels in oceans across the globe, from supposedly pristine Arctic waters near Norway to the coasts of China, Chile, Canada, Britain, and Belgium, Reuters reported. The findings from several recent surveys are the latest evidence that plastic pollution isn’t just ending up in marine environments, but also in…

Climate change: Self-enhancing effect cannot be explained by soil animals
When the soil warms up, it releases more carbon dioxide (CO2) – an effect that further fuels climate change. Until now, it had been assumed that the reason for this was mainly due to the presence of small soil animals and microorganisms that would eat and breathe more in warmer temperatures. However, a new study…

Origins of photosynthesis in plants dated to 1.25 billion years ago
The world’s oldest algae fossils are a billion years old, according to a new analysis by earth scientists at McGill University. Based on this finding, the researchers also estimate that the basis for photosynthesis in today’s plants was set in place 1.25 billion years ago.

Mixing State of Black Carbon from Biomass Burning Differs Evidently in Different Combustion Phase
As a short-lived climate forcer, black carbon aerosols in the atmosphere play a vital role in climate change by absorbing solar radiation and altering the formation, lifespan and albedo of clouds. It also provides "seed" for haze formation in urban/regional scale. In northern China, open biomass burning (OBB), such as straw burning after harvesting, is…

Can computers help us synthesize new materials?
Last month, three MIT materials scientists and their colleagues published a paper describing a new artificial-intelligence system that can pore through scientific papers and extract “recipes” for producing particular types of materials.

Study opens window on meltwater from icebergs
Surface water conditions in Greenland’s fjords and in the northern Atlantic Ocean are dictated by what’s going on deep below the surface next to the massive Greenland Ice Sheet, UO-led research has found.Breakaway icebergs, according to research findings appearing online Dec. 4 ahead of publication in the journal Nature Geoscience, are the biggest source of…
