The amount of nitrogen that is excreted by livestock is directly proportional to the amount it is fed . This is according to Chris Reynolds a researcher in nutritional physiology of ruminants  at  the University of Reading , UK.

Dealing with sludge is one of the biggest issues of waste water treatment.

With climate change, flora and fauna shift their seasonal inner clock.  For example, fruit tree blossom earlier than previous years.

Nobody knows the underlying biological mechanisms of the European eels migration . Thanks to an EU-funded research project called eeliad , now about toreach completion, biologists have revealed some of its secrets, including a better understanding of its biology and migration route.

Non-ferrous metals are increasingly in demand because of the electronics industry. "They are used in LED’s, computers, smartphones; this is a much bigger business now," says Kate Hornsby , Waste in Social Environment manager at the Technical University Aachen , Germany.

Not all countries are equal in the face of floods. To provide support for the variety of scenarios encountered, the RAMWASS research project developed a tool for gauging and managing the dangers of floods in specific river zones.

New air pollutant emission targets have just been introduced in the EU. Chance of meeting these new targets has recently been tremendously improved by considerable progress on how emissions from different sources are measured and estimated.

The process was developed by the Water Research Institute (WRI) of the Italian National Research Council and tested and scaled-up as part the EU-funded Innowatech project We know that biological processes offer the cheapest way to treat industrial wastewater.

The discovery of planets in a habitable zone rises the hope that astronomers could soon answer the question of whether we are alone in the universe.

Membranes for water purification are used in many applications and different types of membranes are being developed at the moment. No membrane can filter and purify water entirely, but improvements using novel kinds of membranes are made.

The filter could be used to recycle sewage on a space station, but the main focus is the use of ultra pure water in the fabrication of semiconductors.

Lovingly tended to as far as Kristianstad in Sweden, palms have never had it so good in Northern European gardens. The UK, which has not had a seriously cold winter for about 10 years, is a case in point.
