The worst treatment was kept for the monkeys. The macaques breed of monkeys are small, relatively light primates, which are often used for animal experiments at LPT. \u2018They are kept in cramped conditions in small cages. https://t.co/6D0yisjd9B

A Norwegian Scientist @Vehuardo recently claimed RaTG13 is an "authentic virus"
https://t.co/tAXMNTwdhA
This failed to take into account the work of our DRASTIC colleagues & other published analyses.
This thread is a polite attempt to educate.
2. https://t.co/tw606vgHwp
which says RaTG13 doesn't make sense on how it was sequenced, or how the data got so messed up in the lab as to include copy paste mistakes, bat dna, pangolin dna, rice dna, mice dna, & nobody should use it to form conclusions until it's properly vetted
2 (cont)
"sequence is incomplete & provided segment doesn't function. The identified markers suggest partial match basis & actual virus itself as described by the sequence can't functionally exist due to incoherent structures that appear to be the result of sample contamination"
3. RaTG13 integrity is further attacked here:
The Validity of critical pieces of evidence for the natural origin of SARS-CoV-2 is Dubious, and needed to be

2. A refreshing contrast to the so-called "expert reactions" found here, including from one of the authors of the review (Prof David Robertson)!
"expert reaction to a preprint reviewing the evidence on the origins of SARS-CoV-2"
https://t.co/6kG6rstweP
3. Peter Gutierrez points out in his response that 4 of the authors of “The Origins of SARS-CoV-2: A Critical Review”, also wrote “Proximal Origin of SARS-COV-2”.
His critique focuses on:
1. RaTG13
2. Enhanced adaptation to the human host
https://t.co/eW8b2iK5xe
4. As to be expected, Sydney University and its iconic virologist, Eddie Holmes, who is "not available for interview", are crowing over this biased review
https://t.co/xrjpN1NxpO
This review contains elementary errors as exposed here:
1. https://t.co/YJ50huifly
one of the authors (Stuart Neil) then claimed
"Didn’t N501Y come up in ACE2 TG mice too?

I've recently come across a disinformation around evidence relating to school closures and community transmission that's been platformed prominently. This arises from flawed understanding of the data that underlies this evidence, and the methodologies used in these studies. pic.twitter.com/VM7cVKghgj
— Deepti Gurdasani (@dgurdasani1) February 1, 2021
The paper does NOT evaluate the effect of school closures. Instead it conflates all ‘educational settings' into a single category, which includes universities.
2/
The paper primarily evaluates data from March and April 2020. The article is not particularly clear about this limitation, but the information can be found in the hefty supplementary material.
3/
The authors applied four different regression methods (some fancier than others) to the same data. The outcomes of the different regression models are correlated (enough to reach statistical significance), but they vary a lot. (heat map on the right below).
4/
The effect of individual interventions is extremely difficult to disentangle as the authors stress themselves. There is a very large number of interventions considered and the model was run on 49 countries and 26 US States (and not >200 countries).

In some cases, almost 100% of the light energy can be converted to the second harmonic frequency. These cases typically involve intense pulsed laser beams passing through large crystals, and careful alignment to obtain phase matching.
