Greening seems to have increased during the 1980s and 1990s in the northern hemisphere from the arctic regions down to the 35th parallel of latitude (roughly southern Europe). This has been shown by measurements from space satellites. Some observers, however, have doubted the reliability of these measurements. In the latest issue of Science, a... view more... (2002-06-04)
Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic. view more (2005-09-23)

From Darwin to Adelaide, the length of Australia, 3010 kilometres, without fuel!
On 19 October 30 cars will be jostling for position at the start of the 7th World Solar Challenge in Darwin, Australia. After winning in 2001 with Nuna I, the Nuon Solar Team, from the Netherlands, will be bidding to retain their title. The strong team of twelve from Delft University of Technology and Erasmus University Rotterdam are determined... view more... (2003-10-17)
Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study
A recent decrease in Rocky Mountain snowpack has slowed the release of heat-trapping carbon dioxide gases from forest soils into the atmosphere during the dead of winter. view more (2006-02-09)
Europeans took the long way round - new support for southern exit out of Africa
All non-Africans descend from a group of humans that left Africa by a coastal route across the mouth of the Red Sea to South Asia - rather than by a direct route to Europe - less than 80,000 years ago. view more (2005-05-12)
Kestrel Has Been Announced Moscow Bird Of 2002
The Day of Birds events are taking place in Moscow, this is organised every spring by the Union for the Birds of Russia Protection. This year, besides hanging starling-houses, the ornithologists will for the first time place the nestling boxes for the kestrel in the Vorobyov Hills. The ornithologists hope that the artificial habitations will... view more... (2002-05-17)
Scientists step closer to new treatments for River Blindness
Veterinary scientists in Liverpool have found that some African cattle have natural immunity to a parasite, similar to that which causes River Blindness in humans. view more (2006-04-14)
Small rodents encourage the formation of scrubland in Spain
After two years of research over five degraded landscapes in the National Park of Sierra Nevada (Granada), scientists have established for the first time that field mice base their diet on holm oak and pine seeds, causing a deterioration of the habitats and an extension of scrubland in the forests. view more (2009-08-28)

The autumn timetable is set - for a tree
How does a tree know it's autumn? Thanks to its genes, which are turned on and off in a pre-determined order. But in what order? Scientists at Ume'å Plant Science Center and the Royal Institute of Technology (KTH) in Stockholm have now brought to light the autumn "genetic timetable" of a tree. Philosophers like Winnie the Pooh... view more... (2004-03-31)

Hippo ancestry disputed
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy. view more (2009-03-19)
Pitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from... view more...

A laser uncovers the logic of the stomata function
What you do is sometimes determined by what your neighbours do. Scientists believe that this extends to stomatal behaviour. Stomata are pores placed at the plant surface that allow gas exchange with the atmosphere. view more (2006-12-21)
Green Isle Survives In The Urban Environment
Fortunately, green spots still remain on the map of Moscow tending to be located in the suburbs of the city, in the valleys of the rivers, away from the densely populated communities. Among them there are several little spots which are surrounded by the city being isolated like isles in the ocean. One of them is the forest park of the Timiryazev... view more... (2002-05-07)
Climate change could impact vital functions of microbes
