One thing I didn’t appreciate until London Calling this year is that @nanoporetech.com is now releasing more technical documentation and datasets as blog posts.

New blog post!
In it, I benchmark the new version of Dorado from @nanoporetech.com, which comes with new DNA basecalling models. Short version: big accuracy gains for hac, small improvements for sup.
Check it out for the full results:

Peter Marks’s resignation letter. Everyone should read this.
Peter Marks, MD, PhD
Director, Center for Biologics Evaluation and Research U.S. Food and Drug Administration
10903 New Hampshire Avenue
Silver Spring, MD 20903
March 28, 2025
Sara Brenner, MD, MPH
Acting Commissioner of Food and Drugs
U.S. Food and Drug Administration

Dear Dr. Brenner:
It is with a heavy heart that I have decided to resign from FDA and retire from federal service as Director of the Center for Biologics Evaluation and Research effective April 5, 2025. I leave behind a staff of professionals who are undoubtedly the most devoted to protecting and promoting the public health of any group of people that I have encountered during my four decades working in the public and private sectors. I have always done my best to advocate for their well-being and I would ask that you do the same during this very difficult time during which their critical importance to the safety and security of our nation may be underappreciated.
Over the past years I have been involved in enhancing the safety of our nation's blood supply, in advancing the field of cell and gene therapy, and in responding to public health emergencies. In the last of these, during the COVID-19 pandemic I had the privilege of watching the vision that I conceived for Operation Warp Speed in March 2020 in collaboration with Dr. Robert Kadlec become a reality under the leadership of HHS Secretary Azar and President Trump due to the unwavering commitment of public servants at FDA and elsewhere across the government. At FDA, the tireless efforts of staff across the agency resulted in remarkably expediting the development of vaccines against the virus, meeting the standards for quality, safety, and effectiveness expected by the American public. The vaccines undoubtedly markedly reduced morbidity and mortality from COVID-19 in the United States and elsewhere. Many of these same individuals applied learnings from the pandemic during a flawless response helping… ongoing multistate measles outbreak that is particularly severe in Texas reminds us of what happens when confidence in well-established science underlying public health and well-being is undermined.
Measles, which killed more than 100,000 unvaccinated children last year in Africa and Asia owing to pneumonitis and encephalitis caused by the virus, had been eliminated from our shores. The two-dose measles, mumps, rubella vaccine regimen (MMR) using over the past decades has a remarkably favorable benefit-risk profile. The MMR vaccine is 97% or more effective in preventing measles following the two-dose series, and its safety has been remarkably well studied. Though rarely followed by a single fever-related seizure, or very rarely by allergic reactions or blood clotting disorders, the vaccine very simply does not cause autism, nor is it associated with encephalitis or death. It does, however, protect against a potential devasting consequence of prior measles infection, subacute sclerosing panencephalitis (SSPE), which is an untreatable, relentlessly progressive neurologic disorder leading to death in about 1 in 10,000 individuals infected with measles. Undermining confidence in well-established vaccines that have met the high standards for quality, safety, and effectiveness that have been in place for decades at FDA is irresponsible, detrimental to public health, and a clear danger to our nation's health, safety. and security.
In the years following the pandemic, at the Center for Biologics Evaluation and Research we have applied the same unwavering commitment to public health priorities to the development of cell and gene therapies to address both hereditary and acquired rare diseases. During my tenure as Center Director we have approved 22 gene therapies, including the first gene therapy ever to be approved in the United States. However, we know that we must do better to expedite the development of treatments for those individual suffering from any one of the thousan…

Less than two months to @nanoporetech.com London calling. Anyone secretly testing new pores? Kit chemistry? Devices?

Quick amplicon prep on an @nanoporetech.com sequencer. Loads of service providers out there doing amplicons - @plasmidsaurus.bsky.social do them very very cheaply plasmidsaurus.com

Much more accurate than a gel.

Landmark paper claxon!

'Evaluating the economic and health impact of proactive genomic epidemiology in a hospital setting'

www.medrxiv.org/content/10.1...

Significant savings associated with proactive genomic epidemiology.
Figure 6:
Overall annual potential savings and costs by use of the proactive genomic epidemiology approach
The health economic assessment uncovered yearly net cost savings of approximately € 1·25 million if initiated IPC measures completely halt transmission of clinical isolates after the second patient. The reduction in costs is due to a lower rate of costs for non-MDRO (red) and MDRO (blue) infections, respectively as well as colonization with MDRO (green). The costs for non-MDRO infections (red) are made up of the additional days a patient has to spend in hospital due to the infection (7·8 days), multiplied by the costs per patient for an additional day in hospital (€325). The costs for the colonization with MDRO (green) is composed of the average number of days a patient spends in the hospital (4·6 days), multiplied by the extra-costs incurred per patient per day for the isolation of the patient (€325). The cost for MDRO infections (blue) results from the average number of days a patient with an MDRO infection has to spend in hospital (7·8 days) multiplied by the additional costs incurred per day by a patient with an MDRO infection (€650).

My 1st “computer” - I remember that genesis motherboard being very in the way when we tried to upgrade the RAM!

One of my favorite oddball formats the Sega Genesis found itself in was the Amstrad Mega PC. A 386sx PC that also had an entire genesis motherboard on a ISA card. I'm fascinated by this sort of console/pc hybrid concept.
A picture of the Amstrad Mega PC running Sonic the Hedgehog.  A picture of a Mega PC (sega genesis) controller for the Amstrad Mega PC.  It's the most PC beige you've ever seen.
