This is an excellent article on the non-linearities in weaning ourselves off fossil fuels! As the number of extraction/refining/consumption points decrease, the system grows more susceptible to individual failures, which will cause problems unless proactively predicted and protected against.

As an enthusiast of both DNA origami and phage, this work is so exciting to see! Check out this article about "Bacteriophage-Mimetic DNA Origami Needle" from the laboratory of Kurt Gothelf. I love the concept, idea, and execution! πŸ§¬πŸ¦ πŸ’‰

I am very excited to share our pre-print that was just released on the bioRxiv entitled "Biomolecular Condensates Dictate the Folding Landscape of Proteins" doi.org/10.64898/202...

Very grateful for @jerelleaj.bsky.social and the members of the Joseph Group for their support on this project! (1/4)

Happy new year! A step change in RNA structure prediction, powered by top Kaggle-ers in a collaboration lead by Stanford University and NVIDIA

Happy to have played a small part in the new RNAPro model, significantly outperforming AlphaFold 3 as well as VFold (CASP winners)

And since you want numbers:
- 50% or more decrease in new data center construction
- An increase from $20/month, but not from Google to crowd out the less-diversified OpenAI and Anthropic
- 30% decrease in Nvidia, Oracle (and Tesla, because why not) share prices followed by exciting financial news.

For the LLM industry:
- significant slowdown or halt in new data center construction.
- squeezing existing paid tiers of LLM use, even as inference costs fall
- contagion via the financial markets where falling share prices of the usual suspects and defaults on loans result in VC/bank crises.

Ph.D.s Can’t Find Work as Boston’s Biotech Engine Sputters A life-sciences job in Boston used to be a sure path to a high-paying career, but empty labs and unemployed grads now herald tougher times in the city.

This article is a good look at what happens when an industry (biotech in this case) runs out of steam:

Is the AotY list mostly the big melodeath releases from this year? Yeah, call me basic. Was it a good year for melodeath? Also yes.

Can’t get the texture of the guitar on the Amorphis album out of my head.

A lot of angst whether to put Unreqvited or Orbit Culture in that last slot, but decided for some diversity.

Yeah, it’s suspicious that they didn’t cite design methods or state how they ensured closure. I would for sure flag that if I were a reviewer for this paper.

I didn’t look too closely at this paper, but presumably the design must have enough curvature to overcome the Hairygami effect? The Hairygami paper showed that if you don’t compensate for the entropic effects of the overhangs, you don’t get preferential closure. 🧬
