Read about this Genomics Aotearoa funded project to understand and help the rarest penguin in the world theconversation.com/why-the-race...
New paper out today with @josephguhlin.bsky.social where we did penguin GWAS to better understand disease risk and found that these penguins represent three deep evolutionary lineages www.nature.com/articles/s41...
And our piece in The Conversation about the story theconversation.com/why-the-race...

New paper! 🐧 We sequenced 249 hoiho / yellow-eyed penguins across mainland Aotearoa New Zealand and the sub-Antarctic to understand their history and why a deadly chick disease is hitting the mainland population so hard. #Science #Conservation #Genomics #NZWildlife www.nature.com/articles/s41...

Photographer Richard Robinson & I spent the spring documenting the toughest time of year for Kaikōura's fur seals. In the last 2 years they've faced starvation and a new virus -- now, as bird flu looms, what will this breeding season hold? nzgeo.com/stories/silent-spring 🧪🦭 @nzgeo.bsky.social

🐧We researched one of the world’s rarest #penguins. The yellow‑eyed penguin (aka hoiho/takaraka) isn’t one homogeneous species after all! www.biorxiv.org/content/10.1... #hoiho #conservation #genomics #birds #nzwildlife #endangered #wildlife #nature
We did a penguin GWAS! Turns out that yellow-eyed penguins (or hoiho) are actually three very divergent groups, which we are calling subspecies www.biorxiv.org/content/10.1... @josephguhlin.bsky.social @peterkdearden.bsky.social @annasanture.bsky.social @cegrueber.bsky.social

This is quite late but our lab has a preprint out about a SARS-CoV-2 situation we had in mink in Lithuania back in 2021. It's a doozy with re-emergence of extinct lineages, a country-wide test of all mink farms in Lithuania & some interesting dynamics in mink. www.medrxiv.org/content/10.1... 1/5🧵
Anthropozoonotic spillovers reveal sustained long-term cryptic circulation of SARS-CoV-2 within and between Lithuanian mink farms https://www.medrxiv.org/content/10.1101/2025.07.15.25331253v1
We found RHDV2 in gulls! While the virus is likely to be dietary in origin, this suggests that birds may act as mechanical vectors for virus spread. Work by Steph Waller, @dwinter.bsky.social @eddieholmes.bsky.social @mongoosekiwi.bsky.social et al. journals.asm.org/doi/10.1128/...

Rhys and I found some weird influenza B viruses in fish a few years ago. For 2, the HA's bind a2,3 sialic acid ("bird type receptor"). The Siamese algae eater virus NA has a highly conserved structure and active site. No cross-reactive antibodies in human sera. 👉 biorxiv.org/content/10.1...

I spent about 30 hours over four weeks reading all 716 pages of the report of the Royal Commission into the Covid-19 response, then wrote two articles detailing its findings and recommendations. With the paywall now lifted on both of those pieces, here's what I found. 🧵

Essential reading from @katherinejwu.com @theatlantic.com. For months, we've passively watched H5N1 tear through animals. A year into the cattle outbreak & it remains out of control. H5N1 is everywhere. If H5N1 causes a pandemic, it will be because we let it. www.theatlantic.com/health/archi...

Lots of new viruses (and other known pathogens) here, especially in carnivores and rodents. Of most interest, a bi-segmented coronavirus sampled from diseased red (lesser) pandas (Ailurus fulgens) and that represents a new genus. Work led my Mang Shi and Shuo Su. www.biorxiv.org/content/10.1...

Thrilled to be co-leading these efforts with our colleagues at Scripps Research and UCSD.
In a new $5.7M partnership with @ucsandiego.bsky.social, Scripps Research joins the CDC's CHARM Network as the central data hub. This 5-year initiative will bolster national preparedness for respiratory viruses like influenza and SARS-CoV-2. More:

As usual, Helen is first out of the gate with a great explanatory piece on the CDC's updated technical report on the H5N1 case in Louisiana, with quotes from me and @scottehensley.bsky.social. 👇
The #H5N1 #birdflu virus from a severe case in Louisiana shows it was developing mutations that could help it attach to cells in human respiratory tracts, including a mutation seen in a recent severe case in British Columbia, Canada, the #CDC reported today. www.statnews.com/2024/12/26/c...

Influenza-like viruses in basal chordates. Love it.
Answer: yes, and we think so. We found multiple instances of influenza-like viruses in tunicate metatranscriptomes (shown in red) that fell towards the base of the clade. Here is the phylogeny for PB1, but the pattern held up for the other segments, too.
