It sounds like you want a dictation mic. Philips’s SpeechMike and OM System’s (formerly Olympus) RecMic are big in the healthcare space. My SpeechMike is wireless with a USB dongle and has something akin to a trackpoint for mouse movement, and buttons that can be programmed to send keystrokes.

Dictation mics are not cheap, unfortunately, but you may be able to get used ones for much less.

The periodic table poster under "High binding problems" is billed as evidence of model limitations, but I wonder if it just suggests that 4o is a fan of "Look Around You".

I'm a little disappointed that their linked preprint doesn't appear to include any molecular biology; i.e. they don't actually try to synthesize any of their predicted sequences and test function. It wouldn't be an outrageous synthesis task to make some of the CRISPR-Cas sequences they generated.

Also interesting that AlphaMisense is omitted from Figure 2B; it substantially outperforms the ESM-based ESM1b in our hands. But I guess the idea is that this is a general-purpose DNA language model whereas AlphaMissense is domain-specific for variant effect prediction?

A tangent: does anyone have recommendations for a library for easy Swift-Rust interop? This is a cool tool, but I’d much rather make a GUI natively with e.g. SwiftUI and then call out to Rust for business logic. The previous times I’ve looked into this, both languages had to communicate through a C intermediate, and handling more complex types became a chore…

All sorts of offtopic prompts are unsurprisingly generating nonsensical answers, but even prompting with "lecture notes on clathrin-mediated endocytosis" yielded:

"In the case of clathrin-mediated endocytosis, it is a process used by eukaryotic cells to take up extracellular material and molecules into the cell. It is a mechanism used by cells to take up specific molecules, and it is a mechanism used by cells to regulate the composition of the cell surface. It is a mechanism used by cells to regulate the composition of the cell surface, and it is a mechanism used by cells to take up specific molecules. It is a mechanism used by cells to take up specific molecules. It is a mechanism used by cells to take up specific molecules, and it is a mechanism used by cells to take up specific molecules."

Global models of gene expression for an entire cell are fairly distant at this point, but there is quite a bit of work into modeling transcriptional activity from sequence. If you're interested in reading more, a relevant technology to search for would be the "Massively Parallel Reporter Assay", or MPRA, which couples pools of 10⁴–10⁵+ synthetic DNA sequences with RNA sequencing to measure transcriptional output. Data from MPRA experiments is being used to train models, although these models are not anywhere near a point where you could model the gene expression of all regulatory elements in a cell; they are usually focused on a specific factor or regulatory sequence.

I'm confused. Where does this say the vaccine is mRNA? The Valneva VLA15 website explicitly states "VLA15 is a multivalent recombinant protein vaccine" [1], and the linked press release calls it a "investigational multivalent protein subunit vaccine". Does nobody actually read these things?

See [2], "Subunit Vaccines".

Indeed. Maybe someone with more expertise can chime in — it's not clear to me if getting a vaccine with the chimp adenovirus backbone would preclude the possibility of getting another vaccine based on that backbone in the future (because of immunity to the backbone).

Based on this NYT article [1], some logistics companies planning to store and transport the vaccine are using freezers from Stirling Ultracold. It may just be a curiosity, but their freezers (as the name would suggest) use bona fide Stirling engines rather than the typical two-stage compressors used in most ULT freezers.

As someone in life science research who uses plenty of -80 freezers, I've always been curious about Stirling Ultracold. Maybe they're on to something after all.

It’s always surprising to me to see an article like this that’s vaguely about a person, without seemingly any attempts to reach that person for comment. I’ve filed issued on a few of Michael’s repositories since he left Apple, and he was extremely responsive. I’d be surprised if he ignored Phoronix if they had actually reached out to him.

While "Heroes of CRISPR" is a fairly detailed history of the whole affair, it's always worth noting that it was written by Eric Lander, the director of an institute with a strong vested financial interest in having the story interpreted in a particular way.

Just to clarify — the vaccine uses as its backbone a type of adenovirus that typically infects chimpanzees, modified by the addition of pieces from SARS-CoV-2, but the experiments testing efficacy are performed in mice (specifically, a type of mice engineered to express humanized ACE2).

This vaccine has not been tested in chimpanzees (and actually such experiments would probably be a challenge, since they may have existing immunity to the backbone adenovirus).

(edit: parent comment initially mentioned experiments in chimpanzees rather than mice)

The above is a good example of how results can be "wrong" in theory papers, but I work in an experimental field of research and at least in my world, having a paper present results that turn out to be wrong isn't really all that surprising. Experimental papers aren't proof of phenomena as much as they're an attempt to persuade you of the authors' worldview, which may or may not turn out to be correct in hindsight. This isn't grounds for retraction — there are plenty of well-intentioned and reasonably-interpreted experiments that end up not holding up as the field moves forward.

Again, not saying that papers can't have problems with methodology, assumptions, or — particularly in the case of theory — soundness, but sometimes, "good" papers can be wrong. These papers sit in the body of literature, and are important context for modern findings. I do wonder if there could be some way to indicate to readers without domain-specific expertise that such a paper has been superseded, so to speak.

This calls to mind the ever-relevant “Science: The Endless Frontier” [1] by Vannevar Bush, who more or less oversaw the entire American federal research enterprise during and post-WWII. He famously said that the best thing you can do for scientific progress is give scientists money and then get out of the way (i.e. not even putting out requests for grant submissions in specific domains, like the NIH often does now).

The conspiracy theorist in me can't help but wonder if "leaking" forged documents of this nature could be an effective way for China or another foreign government to sabotage the leaders of the American research enterprise.

Of course, my inner cynic is leaning pretty heavily towards Occam's razor for this one.

Some folks have raised plenty of practical/medicolegal reasons, but it's also worth noting that patients are often not comfortable being told that they have an "anomaly" that their doc is going to sit back and do nothing about. There's a lot to be said for the psychiatric implications of being aware of benign MRI findings.

Even if you (or anyone, for that matter) might be comfortable with that, I think you'd find that a lot of patients wouldn't be.

Some of the comments here don't touch on the practical limitations of this, but here's one — I'm at a 1400+ bed top-10 US academic medical center, and even our outpatient MRI machines book patients until near-midnight because the scans take so long. I'm not sure if we even have the imaging capacity at this point to be scanning healthy people.

Tangentially, it's interesting to see how Samsung's reveal video (at the top of the article) [1] is so uncannily similar to what Microsoft came up with a few years ago for the Surface Studio [2], right down to the music selection. Something about technology killing creativity, perhaps? /s

For lack of a rebuttal to the FDA dissolution comment, which I'm sure others are more qualified to respond to, I wanted to address the efficacy/safety remark:

A growing number of people have voiced objections to the burdens of the FDA's efficacy testing requirements, but it's worth at least thinking about why they're in place. The main issue is that "safety" in the context of pharmaceuticals doesn't mean "perfectly safe" or even "non-lethal" — it really means, "safe enough, given the benefits". Side effects of a chemotherapy drug that can completely eliminate a tumor, for instance, could be acceptably substantial, because it cures an otherwise terminal illness. Side effects of a drug mildly lowering cholesterol levels, by contrast, must be strictly limited, because many Americans may take such a drug for much of their adult lives, sometimes in combination if the effects of a single drug are too weak.

It's hard to know if the benefits outweigh the risks if you don't know what the benefits are. Obviously, this efficacy testing carries a huge time and monetary burden, but without it, contextualizing acceptable risk would be difficult, if not impossible.

The fact is, unfortunately, that Nanopore sequencing (and also, from what I’ve read, PacBio) has a dramatically higher error rate than Illumina sequencing-by-synthesis. In the near future, anyway, I would expect to see inaccurate PacBio/Nanopore long reads being used as scaffolds for accurate Illumina short reads (in fact, this is already happening). Illumina won’t be going anywhere any time soon.

Right, but none of the incidents on that list involved a nuclear missile silo. I read the author's sentence as "It would have been impossible (for Morris or other silo crew members) to start World War Three by accident."

It's important to note that aging is not so much a mechanism to protect against cancer as it is a method to avoid cancer (that is, by dying before cancer develops).

It may not have been expressed the most clearly, but the intention was not quite as you describe. Shelter, clothing, and modern medicine all confer enhanced fitness — I was attempting to suggest that increased lifespan does not.
