HIV-phyloTSI: subtype-independent estimation of time since HIV-1 infection for cross-sectional measures of population incidence using deep sequence data - BMC Bioinformatics
Background Estimating the time since HIV infection (TSI) at population level is essential for tracking changes in the global HIV epidemic. Most methods for determining TSI give a binary classification...

If less than 76.6% of your exploratory ideas fail, you’re not exploring enough…
0.234... is the asymptotic optimal acceptance proportion for Random Walk Metropolis Hastings Markov Chain Monte Carlo.
I conjecture this also suggests to us we can be working at about the right level of ambition if most things we try don't work out.

How about a bit of good news? 8 patients were dismissed from the hospital in Uganda after recovering from Ebola. Many still in the quarantine period so outbreak still officially ongoing, but it's impressive that out of the 9 identified infections, there has only been one death (the index patient).
Uganda discharges all eight Ebola patients, health minister says
Uganda has discharged eight people after they recovered from Ebola although at least 265 contacts remain under quarantine, its health minister said.

Trying something new:
A 🧵 on a topic I find many students struggle with: "why do their 📊 look more professional than my 📊?"
It's *lots* of tiny decisions that aren't the defaults in many libraries, so let's break down 1 simple graph by @jburnmurdoch.bsky.social

Humanity’s history is a battle against infectious diseases. And for most of our history we were losing very decisively.
