U.S. government agencies aren't answering questions about H5N1 bird flu

Nearly a month after announcing that milking cows in a Texas herd had tested positive for H5N1 avian flu, U.S. government agencies have been reluctant to share more information. They haven't said what they know about whether pasteurization kills the virus, and only on Thursday did authorities tell STAT it seems the now 29 affected herds are not part of a single linked outbreak.
This is causing challenges to other countries trying to understand their risk, writes Helen Branswell. "A country with capacity like the United States should be able to generate this information within days," said Marion Koopmans, head of the department of viroscience at Erasmus Medical Center in the Dutch city of Rotterdam. "I would expect very fast, very transparent updates and it's somewhat amazing not to see that happening."
The U.S. Department of Agriculture, which is leading the outbreak's investigation, pushed back against the criticism, saying it is sharing information as it becomes available. But experts believe the delays and what is perceived as a lack of transparency may undermine trust in government agencies, evoking déjà vu from Covid-19 times. Read more.

Dana-Farber retracts paper co-authored by CEO amid ongoing research review
The ongoing investigation into data integrity at Dana-Farber Cancer Institute is continuing to find compromised papers. The latest is a 2006 Science paper on the role of two proteins in endoplasmic reticulum stress co-authored by institute president and CEO Laurie Glimcher. According to the retraction notice, the authors had become aware of discrepancies in the images that made them lose confidence in the accuracy of the findings. The lead author, Claudio Hetz, opposed the retraction.
The new retractions are welcomed by the scientific watchdog community, which is praising Dana-Farber for effectively investigating its past body of research linked to the compromised images, writes STAT's Angus Chen. "It is good to see this institution taking a harder stance against sloppy science and intentional data falsification that many institutes have done in the past," said scientific whistleblower Elizabeth Bik.

The WHO has a new definition of airborne disease transmission
It took two years of contentious debate, but the World Health Organization has published a new report with a set of more accurate definitions of airborne disease transmission. Until now, the official definition limited the label of "airborne" to a few pathogens, such as tuberculosis and measles, known to float in the air and travel long distances. Now, it includes all situations when transmission happens through inhaled particles. "It feels like finally the end of the most stubborn and senseless resistance to accepting this science," said Jose-Luis Jimenez, an aerosol chemist at the University of Colorado Boulder.
What remains unclear is how the new definition of airborne transmission will shape efforts to protect and limit future outbreaks, writes STAT's Megan Molteni. Though the report says that protective measures such as masks and isolation rooms are important to prevent airborne spread, it did not recommend them in all settings, and the cost and politics associated with such measures may prove challenging.
