From the list of things I DO recommend

Spend a high fraction of time on strategy and planning compared to execution. It’s better to take the time to evolve ideas until they are good and execution takes minutes to days not weeks-month. Good ideas meaningfully address your most important problems.

From list of things I really don’t recommend:

Working like every week there is a paper submission deadline but for 6-18 months.

I would abolish the deadlines in general in favour of evolving timeline projections. At specific dates, it only makes sense to report snapshots “this is how things look”.

Defining models and modelling tasks in ways that avoid

“the model knows something that cells don’t”

should be the guiding principle for making models.

Strongly recommend taking a look!
Are you using any of our factor models, such as MOFA? 🛵
You might’ve found it challenging to tailor them to your specific use cases - not anymore!

How many hours per week do you talk to ChatGPT?

I generally do 2-5h in total and several times per day - across coding, science, career, life, health. It’s becoming quite integral. Hard to believe I would say this given what I thought before.

I am wondering what people think about building an AI system to coordinate research. It would be an agent similar to ChatGPT 5. You can talk to it about your research with persistent memory across chats. All chats are used for training without opt-out option.

Hot take. Excessive benchmarking demands on computational method papers slow down progress. Benchmarks in the paper need to show that your solution works well enough for your goals - not that it is the best solution ever proposed or how exactly it differs from all other existing solutions.

How many papers are truly irreproducible and how many show a possible causal path which often isn’t the limiting factor and is conditional on important context (eg mutations, genetics, environment of the experiment)?

Thinking about omnigenic model, “mechanistic bias” in medicine, personalised PRS.

By training GPN-Star on vertebrate, mammal, and primate alignments, we reveal task-dependent advantages of modeling deeper versus more recent evolution. These findings offer new biological insights and practical guidance for developing future gLMs and evolutionary models.

This is truly an incredible breakthrough IMO. Really exemplifies what you get when deep domain expertise (popgen/evolution/disease genetics in this case) fuses with cleverly crafted ML. What u get r sleek, well thought out architectures that absolutely destroy the behemoths. Wow!! 1/

If you feel like you need noise canceling headphones 🎧 - you probably actually need to buy them right now. Don’t delay this decision and loose time trying to operate without them.

Noise cancelling headphones are like your work email+slack - you may be able to work without them but it’s pretty hard.

Has anyone ever seen a house/flat in the UK/Cambridge that had an HRV or ERV system?

If you can’t have windows open at night due to security concerns how are you supposed to ventilate?

I tried closing windows and even with the fan on max CO2 levels never got below 850ppm (bad for sleep quality).

With unprecedented 38× coverage, our atlas resolves single neuron clusters and shows that separate waves of neurogenesis use different modes of molecular identity encoding: discrete in early born and continuous in late born. 3/8
