Usually, it takes a nose to smell, but now - for the first time - scientists have developed a convincing model able to measure odours from pig farms by means of precise measurements of the content of odorants in the atmosphere.

How much and how bad does pig production facilities smell? Now we are able to answer this question by means of a technique developed by scientists from Department of Engineering, Aarhus University, in cooperation with SEGES. They have developed a model that is able to predict pig house odours. The model is based on measurements of odorants by means of the analytical technique PTR-MS.

Alpine forests will be at great risk should weather phenomena such as droughts and torrential rain become more frequent. As a study by the Technical University of Munich (TUM) shows, the mountain forests of the Bavarian Alps have seen a significant reduction in topsoil organic matter over the past three decades. The study authors' recommendation is therefore to preserve, or better still, increase soil humus regardless of climate change by implementing humus-promoting forest management to safeguard the mountain forest's protective function and to mitigate floods.

A Kobe University research group including Associate Professor Maki Hideshi (Center for Environmental Management), PhD candidate Sakata Genki (Graduate School of Engineering, Department of Chemical Science and Engineering, currently employed at Central Glass Co., Ltd.) and Professor Mizuhata Minoru (Graduate School of Engineering) have developed a new analysis method that uses magnetic fields to quickly and accurately measure the concentration of aluminum used to purify tap water. These findings can potentially be used in developing efficient and environmentally-conscious coagulants for water treatment. The findings were presented on May 29, 2016 at the 76th Japan Society for Analytical Chemistry Symposium.

Philadelphia, PA, June 20, 2016 - Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study in Biological Psychiatry.

Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.

Author of the study Dr. Hanan El Marroun, of Erasmus University Medical Center in The Netherlands, said: "this study is important because cannabis use during pregnancy is relatively common and we know very little about the potential consequences of cannabis exposure during pregnancy and brain development later in life."

As Republican and Democratic parties prepare for national conventions this summer, campaign speeches are filled with promises about everything from health care to the economy and national security.

But a national poll suggests presumptive presidential candidates Hillary Clinton and Donald Trump may want to consider their positions on a less-talked about topic: children's health.

Greenland's glaciers are melting, but they do that every year. However, a recent computer simulation sounds the alarm about a 50 percent increase in the freshwater flux since 1990, which is too narrow a timeframe for scientific purposes, it is the target date for the original Kyoto treaty on global warming, but will be a clarion for policy makers.
