En la jungla de asfalto en el centro de una ciudad, las emisiones de dióxido de carbono (CO2) están dominados por los combustibles fósiles quemados por las densas concentraciones de coches y edificios. Investigadores de la Universidad de Boston (UB) han demostrado ahora, sin embargo, que en las áreas metropolitanas que rodean el núcleo de la ciudad, las raíces de las plantas y la descomposición de la materia orgánica en el suelo emite suficiente CO2, en un proceso denominado "respiración del suelo", como para hacer una (inesperada) gran contribución a las emisiones totales.

Scientists of the Tomsk State University have found preserved moose in Western Siberia that have unique features of DNA structure. This discovery of Tomsk scientists will help determine the origin and path of moose movement in the last few tens of thousands of years and gives reason to believe that Siberia is a unique genetic repository. The research has been presented at International Conference "Theriofauna of Russia and adjacent territories" (X Congress of Russian Theriological Society).

Unique moose were found in the southeastern part of Western Siberia. Hunters of the Tomsk Region assisted in this discovery. Along with the license for opening the animals, they got set for the capture of prototypes and a small profile.

Beavers are Britain's native aquatic engineers and their return to sites in Scotland and England is doing wonders for the local environment, write Nigel Willby & Alan Law: restoring wetlands, recreating natural river dynamics and ecology, filtering farm pollutants from water, and improving habitat for trout and other fish.

In Knapdale, damming by beavers transformed a small pond into a wetland of a type and complexity probably unseen in Britain for centuries. On the Bamff estate on Tayside, we found that grazing by beavers trebled the number of wetland plants in 9 years.

Beavers have recently made a tentative return to Britain.

Los japoneses se mantuvieron desinformados desde el inicio de la catástrofe de Fukushima sobre altos niveles de radiación y sus peligros para la salud, escribe Linda Gunter Pentz. Con el fin de anunciar como "segura" el área de Fukushima, el Gobierno aumentó los límites de exposición a veinte veces la norma internacional. En muy corto tiempo, muchos refugiados de Fukushima se verán obligados a volver a casa para soportar niveles dañinos de radiación.

Around the world, banana farmers are fighting a losing battle against Tropical Race 4, a soil fungus that kills Cavendish bananas, the only type grown for the international market. The disease was first spotted in the early 1990s in Malaysia, but has now started to wipe out crops in large parts of South-East Asia as well as in Africa and the Middle East.
