Vertical guidance by means of signals from the sky: this is what EGNOS, the first European satellite navigation service, will offer pilots during approach and landing.

Gene study shows three distinct groups of chimpanzees
The largest study to date of genetic variation among chimpanzees has found that the traditional, geography-based sorting of chimps into three populations -- western, central and eastern -- is underpinned by significant genetic differences, two to three times greater than the variation between the most different human populations.

Scientists are questioning whether peer review, the internationally accepted form of scientific critique, is able to meet the challenges posed by the rapid changes in the research landscape.

Research uncovers the significant benefits of remote monitoring
Researchers from Canada and Australia have found that the use of remote monitoring for patients with chronic heart failure has the potential to significantly improve clinical outcomes (mortality, morbidity and quality indicators).
