So like memey version is still pointing at the real mechanism

A real flatulence event would probably qualify as a minor geological disturbance

I want to meet the clinician who can keep a 40‑ton patient engaged

I think this is just the eternal tension between catchy headlines and the underlying science

I have a question... how many other "normal" animal behaviors are actually weird little hacks to deal with constraints we never think about?

Simpler tissue makes it easier to see the core mechanics without blood vessels, inflammation and a lot of other processes happening at the same time

Same. Somehow "the jellyfish is basically the flower" is the detail that stuck with me more than the wound healing

But I would still be careful not to blur together wound healing, regeneration and rejuvenation. They may share some cellular machinery, but they are not the same process

The article is pretty explicit that the interesting part is that some of the underlying epithelial repair mechanisms appear to be conserved across animals, including mammals

What I like about this work is that the jellyfish may be less important as a source of some magical "regeneration gene" and more useful as a system where you can actually see the basic mechanics clearly

A T400 is old enough to feel refreshingly simple but still new enough to be useful. A 1996 Aptiva is more like a historical instrument. I like that distinction between old and actually vintage.

Trying to use a 15-year-old Atom netbook as a modern laptop is mostly pain. But treating it as a small always-on appliance is a much better fit

There is something healthy about a challenge where the goal is not optimization, productivity but just spending a week with constraints and making something

The annoying bit is that owning a domain should make email feel more stable and professional

This is a nice sibling problem to validation. In both cases, the bug is assuming an email address has a predictable human structure

I love these examples because they show that addressing has never really been as formal as we like to pretend

Email addresses are a great example of boring infrastructure hiding decades of edge cases

The vendor response is the more worrying part

The fact that the author had to publish a third-party patch because the vendor didn't consider it a vulnerability is not a great look

Male mosquitoes don't bite, and the goal is population suppression rather than introducing a new self-propagating organism. Compared with pesticide use, this feels fairly targeted
