Progress in science depends on new techniques, new discoveries and new ideas, probably in that order - {Sydney Brenner}. I write about biotech @MIT @techreview

Moderna believes it could update its covid-19 vaccine with new mRNA instructions (say against a variant) without running a new efficacy trial. Same as annual flu vaccine.
@antonioregalado Just asked this question to Moderna's executive team at #JPM21 (presentation just ended). The expectation is yes i.e. no RCTs for mRNA-LNP vaccines for variants. However, ultimately it is the decision of regulators. Comparison to annual flu vaccine was also made by the team.

Holy crud. People may be immune to CRISPR. "The presence of pre-existing adaptive immune responses in humans to . Cas9 . may hinder the safe and efficacious use . to treat disease, and may even result in significant toxicity to patients"
Wow: thanks to commensal infection with staph bacteria, most people have pre-existing antibodies against commonly-studied Cas9 proteins. This may cause a significant hurdle to using CRISPR in the clinic.

This vainglorious tweet from He Jiankui, creator of the CRISPR babies, is getting a lot of attention. The research was deemed unpublishable because of ethics shortfalls and apparent deception used in the course of the experiment. 🧵.
I am willing to publish my two 2018 papers on the world first gene edited babies, however it must be published in either Nature or Science. It is one of the greatest medical breakthroughs in history, it deserves the honor to be published in Nature or Science.

NIH cancels @EcoHealthNYC program that passed U.S. (NIH) funds to the Wuhan Institute of Virology for genetic engineering of bat coronaviruses. Reason: WIV/EcoHealth not willing/able to produce lab records. NIH in the dark.
“NIH official said EcoHealth Alliance had not been able to hand over lab notebooks and other records from its Wuhan partner that relate to controversial experiments involving modified bat viruses, despite multiple requests.”.

JUUL gets warning letter from FDA for unproven claims that vaping is safe. Company reps played with fire by going around saying what the FDA thinks (99% safer than cigs) and what it will do (approve Juul). Made comments in a school, to kids.
FDA says Juul has "ignored the law" with claims its vape devices are safe -- sends the company a warning letter, requests more documents on advertising efforts

@aparanjape @elonmusk @Rainmaker1973 The difference of any two human genomes---yours versus the reference -- might be on the order of ~50 million base pairs. stored as 10Mbytes? So one form of compression is just the differences.

Altos Labs came out of stealth today with $3 billion in funding. Mission: unravel deep biology of cellular rejuvenation programming. Funders: They don't disclose ((only ARCH)). Full list of the scientists that joined is here.
SCOOP: An insanely well-funded company called Altos Labs is going after "rejuvenation" technology. Yamanaka factors. Epigenetic clocks. CRISPR. Offering academics $1 million salaries and more. Investor rumor mill: Milner, Bezos, ARCH. Musk?.

Everyone will eventually write about Alina Chan, the postdoc who tweeted life into the #lableak theory. Our profile is out today.

holy cow Harvard Medical School dean George Daley is making the case, big time, and eloquently, FOR editing embryos, at #geneeditsummit . he is says technically we are *ready* for RESPONSIBLE clinic use.

Claim: a stem-cell first. This company's IVF technology matures eggs in a culture of iPSC (induced stem cell)-derived ovarian cells. A baby was born in their trial, marking "first ever human birth using using iPSC technology" company claims. couple comment in 🧵.
(1/) We are thrilled to announce a medical milestone–the world’s first live birth using our product, Fertilo, that matures eggs outside the body.

@elonmusk definitely a ton of people claiming to be co-founders. if @neuralink were to include a "Team" page on the site that would clarify for the public at large.

In China, the government has deleted uncomfortable aspects of the history of the early days of SARS-CoV-2. In the US, some scientists are deleting their own contemporaneous records and observations.
Jan 2020. Responding to the demands of covid-19, key scientists begin employing Twitter as a way to speak directly to the public and the press, a transformative event in #scicomm and a fascinating and valuable public record. June 2021:

Quite a story. In a report on adversarial networks, Meta (aka Facebook) unpacks the case of "Edward Wilson," a Swiss biologist who turns out to be a fake "persona" created by China to put a wrench in covid origins hunt. Complete with GAN generated profile image.
I'm expecting the #scicomm reporters chasing #OriginsOfCovd #disinformation to follow up on this story . like never. (Hard ignore!). "China-based Covid disinformation operation pushed fake Swiss scientist, Facebook says"

Hey @andrewyang great answer on geo-engineering! I am a journalist specializing in gene-editing (CRISPR). Do you think American society should purse germline gene-editing of humans? . Thanks!.

Stepping up. A big moment for biomedical science, self organizing to respond. My best and thank you to all the scientists who find their way to the front line.
Wow — dean of University of Washington medical school is asking qualified graduate students to pause their research and instead help run COVID-19 lab tests. Voluntary until compensation structure can be determined

@zarawesome Your tweet proves to be an excellent prompt for OpenAi text-davinci-002, which delivers a serviceable parable in response.

Back in 2018, I profiled a Brooklyn family, the Landsmans, trying to crowdfund a gene therapy for their sick kids. Honestly, I didn't think it would ever happen. I dreaded writing a followup article about how they failed. But last Thursday it did happen. Their son got treated.
In a bid to treat ultra-rare genetic diseases, some parents are embarking on multimillion-dollar quests to finance experimental gene therapies—and designating their own children as the first recipients.

There are several CRISPR documentaries in production. The first to hit the screen is "Human Nature" by Adam Bolt and produced by @DanRather . It's going to premier this Sunday, Mar. 10th @SXSW . The trailer is just out. Watch: .(1/4)

“LaMDA is sentient.”. Crazy story about Google engineer and occultist who gets suspended after sending a mass email claiming that an experimental AI chatbot called LaMDA is conscious. 1/.
This non-buzzy article by @nitashatiku includes points about the real risks of non-GAI from @mmitchell_ai as well as a succinct summary of the root of the issue by @emilymbender: “We haven’t learned how to stop imagining a mind behind [the machines].”.
