Scale of human impact laid bare in new island study
30 April 2021
When humans arrive on an island they have an immediate and dramatic impact on the ecosystem, according to a new international study which included scientists from The Australian National University (ANU).
The study looked at 27 remote islands across the globe and found they had something in common. When humans arrive on these islands the ecosystem immediately starts to change. But even more importantly, it keeps changing - it s still changing now in most cases, ANU co-author Dr Simon Connor said. The change is also permanent. There s no going back because our impact as humans is so profound. This is worrying because the islands have really special biodiversity, including species that aren t found anywhere else in the world.

: Synairgen plc (LSE: SNG), the respiratory company developing inhaled interferon beta (IFN-beta) for the treatment of severe viral lung infections, today announces results from the Home Cohort of its SG016 Phase II trial of SNG001 in SARS-CoV-2 infected patients and data from the combined analysis of the Hospital and Home Cohorts.
SNG001 is a formulation containing IFN-beta for nebulisation, allowing it to be delivered directly into patients’ lungs. A number of studies have reported that the SARS-CoV-2 virus suppresses natural production of IFN-beta and prevents induction of anti-viral responses by infected cells. Furthermore, some people have deficiencies in antiviral IFN signalling that make them more vulnerable to spread of the virus from the nose into the lungs where it can cause severe breathing difficulties. These findings provide a rationale to deliver IFN-beta directly to the surface epithelial cells of the lungs, the primary site of virus infection in the lungs, to pr
