Current food production systems could mean far-reaching habitat loss
The global food system could drive rapid and widespread biodiversity loss if not changed, new research has found.
Findings published in Nature Sustainability shows that the global food system will need to be transformed to prevent habitat loss across the world. It shows that what we eat and how it is produced will need to change rapidly and dramatically to prevent widespread and severe biodiversity losses.
The international research team was led by the University of Leeds and the University of Oxford.
Dr David Williams, from Leeds School of Earth and Environment, and the Sustainability Research Institute, is a lead author of the paper.

What is the most common form of human infrastructure in the world? It may well be the fence. Recent estimates suggest that the total length of all fencing around the globe is 10 times greater than the total length of roads. If our planet’s fences were stretched end to end, they would likely bridge the distance from Earth to the Sun multiple times.
On every continent, from cities to rural areas and from ancient to modern times, humans have built fences. But we know almost nothing about their ecological effects. Border fences are often in the news, but other fences are so ubiquitous that they disappear into the landscape, becoming scenery rather than subject.

Berlin researchers develop UVC LEDs to fight coronaviruses
In the joint CORSA project, SARS-CoV-2 and other respiratory viruses on surfaces and skin are to be deactivated by using UVC light. The project team is developing special UVC LEDs for this purpose and is investigating parameters such as wavelengths, irradiation doses and virus habitats. The German Federal Ministry of Education and Research is supporting the three-year project from 2021 with a total of three million euros.
Like bacteria and fungi, viruses can be inactivated by UVC light. However, for the current coronavirus, no reliable data on the optimal wavelengths and irradiation doses have been available to date. This is to change with the CORSA project (Deactivation of SARS-CoV-2 by UVC light and tolerability for humans), which has commenced.
