Ecology, The Environment and Conservation

There are always oil spots near the petrol stations. Rainwater washes them away, polluting the environment. Researchers from Perm have developed a refining unit for cleaning rainwater sewage from petrol stations. It was successfully tested in Moscow and Perm.

The unit base is a new filter – “Kombi” – made of fibrous carbon sorbent, which is produced by coagulation of chemical cellulose fibres in a special way. The filtering process consists of three stages – settling, refinement through the

Conservation-oriented parks and reserves are fairly common on land, but comparatively few marine regions receive protection from human activities. This situation has, for the most part, elicited little concern, owing to the widely held belief that the large geographic ranges of most marine species would ensure their survival. But new research on restricted-range marine life—that is, species limited to small areas—challenges that idea, identifying 10 regions where further damage to coral reefs could l

Nuclear tests up gene mutation risk.

People in the remote former Soviet republic of Kazakhstan who were exposed to fallout from nuclear-weapon tests have more genetic mutations in their eggs and sperm than normal, researchers have found 1 . Their children could inherit health defects caused by such mutations.

The Soviet Union detonated 470 nuclear weapons at the Semipalatinsk nuclear-testing site between 1949 and 1989, many above ground. The blasts showered r

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
