A paper published today (26.11.02) in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the nematicide, aldicarb, on soil organisms was also studied.

The transgenic plants had an adverse effect on the fungal component of the soil microbial community, while the nematicide adversely

New test will be cheap, less invasive, and could take only minutes

Scientists from Imperial College London and the University of Cambridge have developed a rapid new blood test which may help predict the likelihood of a heart attack.

The research published in Nature Medicine shows how a new science, developed in the Imperial College laboratories, called Metabonomics, can be used to test for coronary artery disease, using minimally invasive procedures.

The test, wh

Patients with acute respiratory distress syndrome (ARDS) rely on mechanical ventilation to breathe, however routine suctioning to remove debris that may be blocking their airways can cause lung tissue to collapse. New research published in Critical Care explains how a new technique involving the re-inflation of lungs after suctioning can lead to a marked improvement in the condition of patients with acute respiratory distress syndrome.

Acute respiratory distress syndrome is a devastating inf

Using a tiny wireless sensor developed at Oak Ridge National Laboratory, doctors will know in minutes instead of hours if an organ is getting adequate blood flow after transplant or reconstructive surgery.

Conventional methods for assessing circulation involve invasive procedures or extensive laboratory testing. In some cases, by the time doctors realize there isn’t adequate blood flow to an organ or tissue, irreversible damage already has occurred.

“Our goal is to offer a te

In the current crisis of global biodiversity loss, the discovery of new species is a welcome addition. But the recent finding that the mountain brushtail possum, an arboreal marsupial mammal of Australian wet forests, is actually made up of two species also poses new conservation challenges.

The new species is proposed in an article in the latest Australian Journal of Zoology (Volume 50, Issue 4), authored by Earthwatch-supported biologist Dr. David Lindenmayer (Australian National Universit

The basque company SK10, which works in the integration of aeronautical structures, has given a significant step forward in its innovation range within compound materials of carbon fibre.

Recently, SK10 has signed with the company EADS-CASA a contract for the development, industrialisation and subsequent mass production of the leading edges of the horizontal stabiliser for the new aircraft Falcon F7X, of the French company DASSAULT.

The development of horizontal stabiliser
