ERM-AE200: A new CRM for the authentication of wine
Authenticity, adulteration and fraud are significant challenges for the wine sector. The addition of exogenous sugar to grape must in order to increase the alcohol content after fermentation may lead to illegal practices and fraud. Such adulterations are detectable by a combination of analytical techniques based on stable isotope ratio analysis (SIRA). Among them, nuclear magnetic resonance ...

Research provides insight into the impacts of droughts in dry Alpine forests
The impacts of drought on European trees are of high concern, especially under a changing climate. New research has indicated that, if summers become continually drier, sensitive species, such as larch and spruce, will suffer reduced growth in some Alpine areas. This could potentially compromise ecosystem services provided by forests in these areas. Drought can have major impacts on the growth ...

Texas: Can`t Tie Water Contamination to Drilling
The amount of explosive gas tainting a North Texas neighborhood's water supply has increased in recent years, but the state's oil and gas regulator says it can't link the methane to drilling activity nearby, according to a report it released Wednesday. The state Railroad Commission has found that the contamination has gotten worse in most of the private water wells it tested in September 2013 ...

Methane release could cause abrupt, far-reaching climate change
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature. The shift triggered events that resulted in global warming and an ending of the last 'snowball' ice age. The ...

New monitoring tools for petrol additive MTBE in groundwater
Methyl tertiary-butyl ether (MTBE) is a petrol additive which can contaminate groundwater supplies. MTBE often breaks down naturally in the environment, but regulators need to be certain that this is taking place. New research highlights a number of tools in development that may offer better data on spilled MTBE in the environment, and improve the ability to monitor its degradation. MTBE is added ...
