Guiding decisions about Spirit Lake and Toutle River at Mount St. Helens

A new report offers a framework to guide federal, tribal, state and local agencies, community groups, and other interested and affected parties in making decisions about the Spirit Lake and Toutle River system, near Mount St. Helens in southwest Washington state. The process should include broader participation by groups and parties whose safety, livelihoods, and quality of life are affected by decisions about the lake and river system, the report says.

Extreme fieldwork, climate modeling yields new insight into predicting Greenland’s melt

A new study brings together scientists from land hydrology, glaciology and climate modeling to unravel a meltwater mystery. Researchers discovered that some meltwater from the lakes and rivers atop the region's glaciers, is being stored and trapped on top of the glacier inside a low-density, porous 'rotten ice.' This phenomenon affects climate model predictions of Greenland's meltwater.

Many more bacteria have electrically conducting filaments

The microbiologists who have discovered electrically conducting microfilaments or 'nanowires' in the bacterium Geobacter, announce in a new article that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments.

Marine mammal beachings not likely due to space weather

After a collaboration between NASA scientists and marine biologists, new research rules out space weather as a primary cause of animal beachings.

Guanidinium stabilizes perovskite solar cells at 19 percent efficiency

Incorporating guanidinium into perovskite solar cells stabilizes their efficiency at 19 percent for 1,000 hours under full-sunlight testing conditions, report scientists.

Transformation to wind and solar achievable with low indirect GHG emissions

Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.

Toxoplasmosis: How a cat parasite exploits immune cells to reach the brain

Scientists have previously shown that a parasite from cats can infect people's brain and affect our behaviour. Now, researchers at Stockholm University have discovered how the parasite takes control of our cells.

First study to measure the carbon footprint of surgery suggests where emissions reductions are...

Choice of anaesthetic gas is a significant contributor to emissions, particularly in North American hospitals using desflurane, instead of cheaper, low-carbon alternatives. The first analysis of the carbon footprint of surgical suites at three hospitals in the UK, Canada and the USA highlights that the choice of anesthetic gases used in surgery can be a major contributor to greenhouse gas emissions from operating theaters.

Study finds ways to avoid hidden dangers of accumulated stresses on seagrass

A new study has found ways to detect hidden dangers of repeated stresses on seagrass using statistical modelling. The research found cumulative maintenance dredging which affected the light on the sea floor increased risks on seagrass survival. It found, globally, seagrass meadows can be at risk of collapse from accumulated effects of repeated dredging and natural stress.

New mapping technique can help fight extreme poverty

A new mapping technique shows how researchers are developing computational tools that combine cellphone records with data from satellites and geographic information systems to create timely and incredibly detailed poverty maps. Unlike surveys or censuses, which can take years and cost millions of dollars, these maps can be generated quickly and cost-efficiently.
