Northern winter and summer look very different[1] (and those don't even capture sea ice).

I've puzzled over how to represent such variation. Especially with deeper time paleogeography, where those 100 kyr of ice ages and sea level changes can be the variation which needs to be aggregated.

One approach is sampling biased by similarity. So you snag points in time, from similar times of year and climate states. If the interactive allows twiddling those, it might not be too misleading.

One approach is open-shutter motion blur. The sometimes-there sometimes-not semi-transparent ice sheets.

One approach is, maybe call it flickered multiples. If one was showing a year, the visual could rapidly cycle through the months.

Any others?

Clouds raise similar issues. It's interesting how time-blurred cloud cover changes with seasons and decades and climate.

Thats an interesting point. I think that if the climate difference is important I would allow the user to toggle between summer and winter. Or choose based on the context if you are showing specific events like wars that were impacted by winter weather. From my research (not professional or scientific) ice sheets didn’t move much between seasons so I wouldn’t include them. When you have very large intervals of 100k years when you go further back there could be several ice ages in between so I don’t think it makes much sense there. In what context do you think that this would be important to consider?

Awesome. I'd suggest implementing lakes that were created by ice sheets blocking rivers in the northern hemisphere (in Canada & Siberia).

Great point, I thought about it but decided it was too hard to do. But I will take another look and see if I can find some good data sources for it.

Very cool, the interactivity of this makes this a much better learning tool than a set of static images (for me, at least).

One minor suggestion: on mobile put the date scrubber on the bottom, otherwise my thumb gets in the way of the UI while sliding back and forth through time :)

Also, I’m not sure if a log scale for time makes sense in this case. It confused me for a second, at least.

Great job, thanks for sharing!

Thanks for the feedback! I used log scale because it will be easier to show historical events on the timeline once I implement that. Since much more happened closer to present day

Does this model have operons like https://en.wikipedia.org/wiki/Lac_operon [1] ? I guess they are skipped to reduce the complexity of the model.

[1] This operon was the first that was discovered, the idea is that the cell produce the enzymes to eat lactose only if there is lactose and there is no glucose.

agnosis · 2 years ago
At the moment it does not. As per the paper[1]:

> We do not simulate any operonal structures for protein-coding genes and transcribe each gene individually. Once transcriptomics data becomes available for Syn3A to determine operonal structures, we can incorporate transcription of operons into this model.

Have you ever wondered how life’s most basic units, cells, operate? As a programmer and cell biology enthusiast, I embarked on a journey to simulate the simplest cell using TypeScript.

ChatGPT has seen huge growth to over 100 million users in just a few months, becoming the fastest growing technology ever. It has sparked many questions and discussions, including what the impact on our jobs will be. In this article I will try to explain this and give some examples to show what it can do.

AI systems are becoming more advanced at an ever increasing pace. At some point these programs are going to be so good that we might start to wonder if they are alive. But how will we know? And what does it even mean to be alive, or conscious?
