Two scientists put the carbon dioxide record at Mauna Loa to music, and made a music video of climate change.
An electron microscope has been used to capture the first three-dimensional image of a tiny filament, or strand, of an essential muscle that the palm-sized water bug Lethocerus indicus uses to fly. This image shows, for the first time, the individual molecules in the filament in a relaxed state, which is necessary to re-extend muscles.
CDC today announced updates to its interim guidance for pre-pregnancy counseling and prevention of sexual transmission of Zika based on ongoing assessment of available data, primarily extending the timeframe for men with possible Zika exposure but no Zika symptoms to wait before attempting pregnancy with their partner and extending the time for use of condoms by these men to protect against sexual transmission of Zika virus infection.
Lake brownification, eutrophication decrease the content of essential fatty acids in fish used in...
Eutrophication and brownification change phytoplankton community structure and decrease the production of essential omega-3 fatty acids in lakes. Perch growing in oligotrophic clear-water lakes contain 1.5-1.9 times more essential omega-3 fatty acids than those grown in eutrophic and brown-water lakes.
An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance. The first five adverse outcome pathways have now been published by experts. The AOPs are novel knowledge management tools in toxicology and are useful for supporting risk assessment to human health. They are also valuable for helping to avoid animal testing through the use of alternative methods.
Genetically engineered crops are no different from conventional crops in terms of their risks to human health and the environment, according to a new report.
In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers who scoured medical literature on the topic and found what they say is worrisome animal research.
