I say this on my tours, we 'know' very little. In fact, we know nothing. I don't know is honest!! It's humble, and its real.
In Egypt there's too much to know, so 'we don't know' is the truest statement there is. https://t.co/IajqsQGdJ8
Another reminder to relax and trust the journey. Become comfortable saying "I don't know."

https://t.co/8ICvHxE9QL is easy & fun to follow for our smallest of people #EYFS. Early childhood is the perfect stage to introduce the core concepts of what it means to be a global citizen. For our reception & KS1 children please take a look at this fabulous free resource
https://t.co/tZx8UIS58Q Storytelling is a powerful communications tool and helps children remember lessons and virtues that they will use in everyday life. The idea is to simplify the lessons of the (SDGs) so young children can relate to – and better understand – the SDGs.
For older children here’s a board game that aims to help teach children around the world about the Sustainable Development Goals in a simple and child-friendly way
This is a lovely free book for children to enjoy flicking through themselves https://t.co/ScMbQCfpjl Elyx, the United Nations’ digital ambassador, uses various expressions and actions to help demonstrate the meaning of each Sustainable Development Goal.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.
https://t.co/FBfXhUrH5d
Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
