Horrific news from Iraq where feminist activist and human rights defender Yanar Mohammed, co-founder and director of the Organization of Women's Freedom in Iraq (OWFI), has been assassinated by gunmen outside of her home just days after returning from Canada.

There haven't been new reports of #H5N1 infected dairy herds in the US for several months, but I keep an eye on the #USDA page where they're posted. Sometime in the past few weeks 4 more herds were added to Idaho's total. Infections were last April-May. publicdashboards.dl.usda.gov/t/MRP_PUB/vi...

Integrating measles wastewater and clinical whole-genome sequencing enables high-resolution tracking of virus evolution and transmission Measles outbreaks have surged globally in recent years, but current surveillance systems have limited capacity to monitor measles virus (MeV) transmission and evolution at population scale. Although M...

New preprint from our Gates-funded Modjadji initiative showing that whole-genome surveillance of measles virus from wastewater greatly expands our ability for monitoring and control.

Here, with our colleagues in South Africa - U.S., unfortunately, likely up next.

Mapping the specificity of H3N2 strain-specific and cross-reactive human neutralizing antibodies elicited by the 2025-2026 influenza vaccine An H3N2 variant, named subclade K, continues to circulate widely during the 2025-2026 influenza season. This virus possesses a hemagglutinin (HA) protein that has eleven substitutions relative to the ...

Our preprint examining the specificity of human antibodies that cross-react with subclade K H3N2 viruses was posted this morning on medRxiv. These studies have implications on what vaccine strains should be selected for next year’s influenza season. 1/

She wasn’t supposed to perform in Verdi’s β€˜Rigoletto’ at the COC. It’s a star-making turn for the ages Canadian soprano Sarah Dufresne, a late replacement in the role of Gilda, marks a astonishing COC debut in this somewhat uneven remount production.

Sarah Dufresne in Rigoletto at @canadianopera.bsky.social is a revelation. A "star-making turn" as @joshuachong.bsky.social writes. She sings Gilda in one more performance, Feb. 8. I was lucky to hear it!

5 more dairy cows tested positive for #H5N1 #birdflu antibodies on the Dutch farm where a previous cow tested positive. No surprise that if 1 was positive, others would be too. This dairy farm is the first outside the US to report H5N1 transmission. www-melkvee-nl.translate.goog/artikel/1450...

Great article by @ainsliecruickshank.bsky.social on the CWHC funding situation, which limits our ability to monitor for diseases like #AvianInfluenza in wildlife.

We so appreciate of the support our partner funding agencies provide. Folks in those agencies really care about wildlife health.

Underfunding threatens Canada’s wildlife disease response | The Narwhal As bird flu and chronic wasting disease spread, experts say Canada’s wildlife disease monitoring network needs more resources to respond

Damien Joly, the chief executive officer of the Canadian Wildlife Health Cooperative, is warning a lack of funding for wildlife disease monitoring is undermining Canada’s ability to detect and respond to emerging threats to biodiversity, agriculture and human health.
