Indigenous communities are rejecting non-indigenous energy projects in favor of community-led sustainable energy infrastructure.
Certain types of bacteria and viruses are readily ejected into the atmosphere when waves break; others less so, researchers reported May 22. A team of chemists, oceanographers, microbiologists, geneticists, and pediatric medicine specialists are attempting to understand how far potentially infectious bacteria and viruses can travel and if those that pose the greatest risks to public health are among those most likely to escape the ocean.
Researchers at The University of Texas at Arlington have found a correlation between a strong immune response in diseased corals and a lower expression of genes associated with growth and reproduction.
Today, only the eldest inhabitants of the Danube Delta recall that, in the past, you could skate on the river practically every winter; since the second half of the 20th century, Europe's second-largest river has only rarely frozen over.
Depending on the lighting, the surface of appropriately crafted nanoparticles can change its topography. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have shown that the molecular mechanism they have designed makes it possible, by the use of light, to effectively uncover or hide catalyst molecules. The technique they present leads to qualitatively new possibilities to control the course of chemical reactions.
Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings.
Previous studies have found an association between two commonly used agrochemicals (paraquat and maneb) and Parkinson's disease. Now U of G professor Scott Ryan has determined that low-level exposure to the pesticides disrupts cells in a way that mimics the effects of mutations known to cause Parkinson's disease. Adding the effects of the chemicals to a predisposition for Parkinson's disease drastically increases the risk of disease onset.
Experimentalists conducted a simulation of future conditions in the Red Sea caused by global warming and acidification, while simultaneously increasing levels of nutrients such as nitrate and phosphate. They found that when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. Algal dominance over corals in the reef means losing all of the beauty and biodiversity of the coral reefs.
Rice grown at higher carbon dioxide (CO2) concentrations, like those possible later this century, has lower nutritional value, according to a study that evaluated rice grown in Japan and China under simulated carbon dioxide increases.
Higher levels of carbon dioxide will result in major reductions in the nutritional quality of rice -- a food staple for half the world's population, a new study finds. It was based on research in China and Japan on 18 common strains of rice. The study reports declines in protein, iron and zinc in rice grown in controlled atmospheric CO2 concentrations that scientists think will exist by the end of the 21st century.
