Many of the arguments shorturl.at/kDNX5 are correct but @guardian should be careful not to exaggerate statements of scientists & misinform the public. #Thread
In particular it is questionable whether scientific data that are not publicly available and thus not verifiable should be communicated in newspaper and used to make moral and ethical judgements.
#Stem cells and #EmbryoModels offer tremendous potential for understanding how we come to be and can have a very significant impact on public health. As noted in this article, they can bring profound economic, social, and environmental benefits.
The scientific community is aware of this and of the development raised here. In consequence it is acting, at the right pace and in the right forums see e.g shorturl.at/xIT57.
It is a hard slog to make scientific advances while drafting a roadmap for incremental, justified usage of stem cells that could maximize benefits to society.
Scientists go thru a very thorough peer review process to publish their findings. The potential discoveries reported in these publications are then verified by other scientists, and are sometimes found to be incorrect.
This lengthy process is essential to ensure that the discoveries can be adequately communicated to the public.
The reports @guardian published from #ISSCR are an example of hasty reporting that flirts with sensationalist journalism. They also ooze ignorance of the field they are reporting on, and can have dire consequences for research and curtailing potential societal benefits.
Scientists should also be careful about how they communicate with the press. They must report on their research in a timely fashion and in a clear and unambiguous manner to make oversight understandable and transparent and to hold researchers accountable to maintain public trust.
See basic ethics principles isscr.org/guidelines/blo…
We cannot stop rogue individuals with particular agendas that can derail ongoing processes but their statements should be checked before publication.
As a Developmental biologist, I welcome the interest of @guardian in our field but would appreciate it if they, and particularly their reporters, could inform themselves better about the complex issues that they discuss before going to press so as not to provide misinformation
The good news is that these articles have put #DevBio in the eye of Society and that this will give the public a broader view of #Biology.
However, as the @guardian knows, fake news are not a good way to shape society and I hope that they learn some lessons from this episode. The community will be very happy to work with them.

Something strange is happening in certain realms of biology. Let me tell you a story
A scientist (let’s call them scientist nr 1) and a journalist make the announcement, in the form of an exclusive, of an important discovery that triggers a wave of headlines around the world.
There' s no evidence to judge the statement & when, by force, it's made available, the statement proves to be false. The headlines triggers other scientists to post related findings. One of them, scientist nr2, shows exactly what scientist nr1 claimed to have achieved but hasn’t.

It is difficult to understand why @Nature publishes papers like this nature.com/articles/s4158… whose title promises much but which in the end is, simply, a data set with little insight & a number of misleading statements.
Perhaps the most valuable figures, which are not discussed in sufficient detail, are 2d and 4b where there we can see some spatial expression. Rather than genes that are the same, it would have been good to see differences.
Overall the technical work is good, probably useful, but the study is a superficial and misleading annotation of the data set to cell types: CDX1 and OTX2 as markers for Definitive Endoderm? HOX as a marker for the node?.

#BSDBGenSoc2020 final part
The results show that gastruloids are organized and that this organization corresponds to that of the embryo; see go.nature.com/3d0lB6b for details.
One surprising observation here is the differentiation trajectories of NMPs and, in particular the gene expression sequence of somitogenesis: Bra ->Tbx6 -> Uncx4.1.

#BSDBGenSoc2020 These days we all have other things in our minds, it is difficult to concentrate and many of my thoughts R w/ family anf friends in #Spain) but discussing our work, is an important part of our being and it is going to be important in the weeks and months to come.
While many, all, of us rather do al this in person, we are going to have to adjust in the weeks to come. #BSDBGenSoc2020 is a good way to explore how we are going to do it so, THANKS @_BSDB_ and @the_Node for organizing and running this.
My Tweetorial follows the phenomenal one from @TimFulton_1 @SteventonLab (with whom @AMA_Lab work closely) this morning and is very related.

And now onto the tweetorial in the form of a loooong thread.
