Dear Prof. Holton, An innovative idea; however all of the 30 kb genome may not be useful for specific detection - SARS-CoV1 and SARS-CoV2 share 80% identity. A similar fluorescent detection approach for SARS Cov2 -- using the indiscriminate collateral activity of Cas12 nuclease -- has been report

One problem I see is the sputum, there’s a reason why swabs are made to get sufficient viral material. Since stool samples test PCR positive that might be an easier approach to get sufficient viral material. As a side note, these are not infectious anymore, or at least one has not been able to inf

In order to do global survelinace of this new virus I figure we're going to need billions of tests.  The biggest barriers I believe are logistical.  Shipping back and forth to a central labs isn't going to cut it, and neither are test kits that cost $800 each. I think I may have a plausible wa

That's a great news! But please be aware that those data are extremely anisotropic. The ones below the detector are partially absorbed by the experimental table. Your refinement must take this into account! Gianluca Santoni, serial crystallographer ESRF structural biology group 71 avenue des

We managed to remove the detector and consequently all the instrument noise using the same procedure. Remarkable effect - absolutely noiseless images. We call it the Adjusted Pixel Readout Index Linked effect. There must be an Ig prize in this. (shameless but serious plug - our Crystallization

That is awesome.  It means we can add data up to a kilometer out, and start modelling quarks? I urge the community to deposit all raw data to a virtual detector of 1km in size - I'm sure Google will happily stump up for the storage costs, the business case is unarguable. On 01/04/2020 05:

Dear colleagues, We, the developers of a program for paired refinement, have found a remarkable feature that should be shared with the community. The fact that data beyond the arbitrary cutoff may cause an improvement of electron density and make your models better is generally accepted. We foun

1. We need renowned scientists on Twitter because it is one of the best ways to spread words worth reading, mostly at these times when so many pseudo-scientists are influencers on social media (or worse, some even have a show on Netflix). 2. I'm voting for Mass Spec right now Cheers, @_biojmg On T
