Sequence data from the new Ebola outbreak in DRC suggests it is indeed a new spillover.

And just incredible to see the virus sequenced and the data publicly shared less than 24 hours after confirmation of the outbreak.

Climate-sensitive disease data integration has been challenging due to variations in spatial & temporal resolution of inputs as well as multi-modality (satellite imagery, tabular, genomic..). We built a tool to makes it easier to perform data integration: wellcomeopenresearch.org/articles/10-...

So proud of Dr. Joseph Tsui, whom I had the great pleasure of co-advising with Oliver Pybus, for finishing his DPhil yesterday.

Many thanks also to his examiners, Mike Osborne (Oxford Computer Science) and Jess Metcalf (Princeton Ecology/Evolution).

Europe’s choice is clear.

To put science at the heart of its economy.

To become the home of scientific freedom and collaboration.

And to welcome talent from all over the world.

I’m glad to present the first elements of our Choose Europe Initiative.
