🍭 Glycans are biology’s sugar code—super complex, super important. Thanks to AlphaFold3, we can now model their interactions with proteins! 🧪 Our new workflow unlocks fresh ways to explore immunity, infection & disease.

It’s not just about this or that nameserver or browser, or how long it’s down, or if it’s intermittent (though those things are important, especially to clinicians and their patients); it’s this: “What if NCBI is not a permanent repository?” 🧪 🧬
It sounds like things are functional atm but what if NCBI is not a permanent repository?
Are existing NCBI projects preserved in European Nucleotide Archive if NCBI goes down? 🧬 🖥️

The NIH website, including NCBI, GenBank, and BLAST are down. I thought it might be a brief outage so waited 12 hours and checked again before posting this. They’re still down.
It is hard to express just how fundamental these tools are to biology and medicine: research, applied, public and private.

Neat 🧪
Should have tagged this 🧪 Follow along to see some of our labs new insights into how cells change shape and move
While our bodies seem static, our cells are constantly changing shape or on the move during tissue homeostasis or wound repair & even more dramatically during embryonic development, during events like gastrulation. Defining how cellular machines mediate these events is a key task for our field 1/n
