New species of ancient chirping giant pill-millipedes from Madagascar already threatened

Posted: 06 Jun 2014 07:20 AM PDT

An integrative inventory of chirping giant pill-millipede species in Madagascar revealed seven new species, many of them microendemics. These microendemics that can only be found in small forest fragments, less than a few hundred meters long and wide, are possibly threatened by rainforest destruction.

Fecal source tracking in Norwegian water catchments: New methods

Posted: 06 Jun 2014 06:15 AM PDT

A set of methods for the detection of fecal pollution in Norwegian watercourses has been tested and implemented. The methods, which combine microbial and molecular biological techniques, can give answers as to whether the contamination is a result of human or animal excreta. In addition, the methods provide grounds for assessing whether the water pollution poses a health risk or not.

Drastic cut in electricity bill for supermarket in Norway

Posted: 06 Jun 2014 06:15 AM PDT

A newly built mini-supermarket was opened last autumn in Norway by a government minister to the sound of a brass band. Throughout the winter, it used 30 per cent less electricity than four comparable stores in the capital of mid-Norway, where of course the outdoor temperature was the same for all of them.

Infection in malaria-transmitting mosquito discovered

Posted: 06 Jun 2014 06:11 AM PDT

The first evidence of an intercellular bacterial infection in natural populations of two species of Anopheles mosquitoes, the major vectors of malaria in Africa, has been found by scientists. The infection, called Wolbachia, has been shown in labs to reduce the incidence of pathogen infections in mosquitoes and has the potential to be used in controlling malaria-transmitting mosquito populations.

For forests, an earlier spring than ever: climate change leads to increased growing season and allows forests to store more CO2

Over the last two decades, spurred by higher temperatures caused by climate change, scientists say, forests throughout the Eastern US have experienced earlier springs and later autumns than ever before.

Climate change: Termites, fungi play more important role in decomposition than temperature

Posted: 05 Jun 2014 03:36 PM PDT

Climate change models could have a thing or two to learn from termites and fungi, according to a new study. For a long time scientists have believed that temperature is the dominant factor in determining the rate of wood decomposition worldwide. Decomposition matters because the speed at which woody material are broken down strongly influences the retention of carbon in forest ecosystems and can help to offset the loss of carbon to the atmosphere from other sources. That makes the decomposition rate a key factor in detecting potential changes to the climate.

New evidence links air pollution to autism, schizophrenia

Posted: 05 Jun 2014 12:57 PM PDT

A new study describes how exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia. The mice performed poorly in tests of short-term memory, learning ability, and impulsivity. Study authors say the findings are very suggestive that air pollution may play a role in autism, as well as in other neurodevelopmental disorders.
