Smart process cleans up contaminated water.

A smart material identifies and destroys toxic pollutants in water. When exposed to the offending molecules, tiny light-emitting zinc oxide particles glow dimly, burn them up, and glow brightly to show they’ve finished 1 .

The advantage of such an approach, say Prashant Kamat and co-workers at the University of Notre Dame in Indiana, is that the energy-consuming burn-up stage switches on only when pollutants are pre

Scientists from Newcastle University are using llama droppings to help combat environmental problems caused by polluted water seeping from abandoned silver and tin mines in the Bolivian Andes.

The project is being spearheaded by Paul Younger, Professor of Hydrogeochemical Engineering at Newcastle University. It has been adapted from a community-based natural regeneration technique which uses waste materials to treat polluted mine waters. Professor Younger pioneered the technique, along with

Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the world’s first ecological experiment.

Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was responsible for greater production of plant matter. This subject, the relationship between biodiversity and the functioning of ecosystems, is curre

South American streams call current nitrogen-cycle theory into question.

Pollution may have altered northern hemisphere forests dramatically. The surprise finding that clean forests use nitrogen differently to polluted ones emphasizes the effect that humans have on the planet’s nitrogen cycle 1 . It may even prompt a rethink of the way that this cycle works.

Humans have added vast amounts of nitrogen to the earth’s ecosystems. The element fertilizes plants. T

The atmosphere and oceans exist in a delicate state of balance according to research co-ordinated by the University of East Anglia (UEA) and published this month by the Natural Environment Research Council (NERC).

The recently completed five year research programme of Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) concludes that atmospheric pollution travels much further than previously thought and that this has important consequences for global chemistry and climate.

A novel research project is looking at ways to recycle plastic bottles for use in the fashion industry in a bid to halt the landfill crisis.

Although recycled PET (Polyethylene terepthalate) has been used in a limited way in the fashion industry, Northumbria University PhD student Yukie Nakano is working to identify the barriers affecting the wider introduction of recycled textile products. Yukie, who is also a research assistant in the Centre for Design Research, is also experimenting with
