The Future Science Group (FSG) journal Melanoma Management, today announces the publication of a new perspective article, in which over 50 leaders in the dermatology field critically assess current screening practice for melanoma.

A new NOAA study shows that methane emissions from the United States did not grow significantly from 2000 to 2013 and are not likely to have been an important driver of the increase in atmospheric methane levels observed worldwide after 2007, as other studies have suggested.

At the same time the pH of the surface waters in these oceans decreased, making them more acidic. Both of these findings imply changes in ocean circulation and primary productivity as a result of natural climate changes of the time. The findings were recently published in Nature Communications.

Oceans changed function

Today the cold Arctic and Nordic Seas are especially efficient areas for uptake of CO2 from the atmosphere. The oceans have been capable of mitigating some of the increase in greenhouse gas release resulting from human activities such as combustion of fossil fuels, by absorbing about 40% of the emitted CO2

“Our research shows that areas in Norwegian Sea had changed their function on  several occasions through the past 135 000 years: Instead of absorbing CO2 from the air, they released more of the greenhouse gas into it.” says first author of the study Mohamed Ezat from Centre of Arctic Gas Hydrate, Environment and Climate (CAGE), Department of Geosciences at UiT The Arctic University of Norway.

Rice University scientists have created an efficient, simple-to-manufacture oxygen-evolution catalyst that pairs well with semiconductors for solar water splitting, the conversion of solar energy to chemical energy in the form of hydrogen and oxygen. 

If you’re bewildered by the term "One Health," you’re not alone. While the use of One Health approaches to solve complex health issues isn’t new, disagreement over a definition has, at times, complicated the concept’s development.
