Excited to share a new paper just published in Neuroepidemiology! We used 22 years of longitudinal data from the Health and Retirement Study to answer a surprisingly unsettled question: How fast does memory decline in older adults without dementia? 🧵👇

We're very excited that our next AMPHIBIAN speaker will be Dr. Alessandro De Nadai, speaking about machine learning in mental health research and interventions on 12/3 at 12:30. Register here: brown.zoom.us/meeting/regi... @rnjma.bsky.social @gemmawallace.bsky.social

Looks like a great methods primer paper from Emma Nichols and Eleanor Hayes-Larson. @timead.bsky.social @g2aging.bsky.social "Common methodological issues in observational epidemiological studies of older adults" bmjmedicine.bmj.com/content/4/1/...

My first R01 goes to study section today, time to bust this out again to see what happens!

Sorry if this seems precious, but as everyone at universities grapples w how to respond to multiple new, genuine crises, I think an underrated way we can help each other is to limit bullshit Have a chance to act in a way that limits someone's emails & meetings abt something fairly trivial? Take it!

I now have multiple sources that say at least one round of NATIONAL ADVISORY COUNCIL MEETINGS will now be announced in the Federal Register.

Next week, QSP will be hosting Dr. Mashu Yang to talk about MNAR data in EMA designs! Come distract yourself for an hour and learn about this important topic for EMA researchers -- register here: bit.ly/3XPShbx

This is a five-alarm fire 🔥 for US science 🧪. (We keep saying that, but it keeps being true 😭.) Trump and Musk are blocking *ALL* NIH grants ‼️ by "exploiting a loophole in the process"—stopping study sections & council meetings. Every biomedical researcher in the country should be screaming. 1/

It is my understanding that when coffee is associated with good health outcomes, then that is a highly reliable causal study, but when coffee is associated with bad health outcomes there exists important confounding issues with the study.

TODAY at 11A US ET, #MELODEM brings you @relajoie.bsky.social and Ganna Blazhenets presenting: "Harmonization of #amyloid-PET quantification for #ADRD research: putting #Centiloids to the test" More deets on MELODEM & how to hop on the distribution list: sites.bu.edu/melodem/

I'm frustrated with the messaging that indiscriminate firings at NIH and proposed decimation of research via changes to indirect rates are about increasing efficiency. Here are some thoughts on how to actually increase returns to NIH investments. shorturl.at/KnWU9 #EpiSky #ScienceSky

We need to shout from the rooftops how and why NIH funded health research is important, and what is accomplished with this work: www.bu.edu/sph/news/art... We're not just doing this because we secretly love reformatting our biosketches & spending weekends writing grants. #EpiSky

My bluesky is full of skyfall, but here's a bright spot: the advanced psychometric methods for cognitive aging workshop 2025 will be fantastic. Here's the info: psymca.org/2025-confere.... Apps due feb 28. #EpiSky #PsychSky

On behalf of the @istaart.bsky.social Design and Data Analytics PIA: Applications are now open for the ΨMCA 2025 Conference on data harmonization & synthetic data in cognitive aging research. 📅 Aug 10–15 2025, Tahoe City, CA. Apply by Feb 28: psymca.org #CognitiveAging #DataScience

Alzheimer’s disease is non-partisan. Cancer is non-partisan. Diabetes is non-partisan. This is a short-sighted policy that could cost thousands of jobs and set biomedical research progress back by years. Contact your local representatives and urge them to stand against this dangerous policy.

I wish there was a way to quantify the collective amount of work lost due to stress and despair over the last few weeks, independent of barriers to funding.

Get in dorks, we're going protesting! STAND UP FOR SCIENCE WITH US ON MARCH 7TH, 2025 WASHINGTON DC AND EVERY STATE CAPITOL Because science is for everyone! Find us at standupforscience2025.org #standupforscience2025 #scienceforall #sciencenotsilence

If you'd asked me a year ago, I might have said "arbitrary and capricious" sounded like fun. Live and learn. Today, "the rule of law" sounds a lot more appealing- and better for health research. www.statnews.com/2025/02/10/n...

Each of the 149 shows in Taylor Swift’s Eras Tour generated about $31 million in local economic activity. Imagine suddenly and permanently losing 690 shows. The 15% indirect cost cap announced by NIH will deprive our communities of $21 billion in economic impact. #keepNIHstrong #science #episky

Breaking news via me and @angusrohan.bsky.social: 22 states sue to block Trump administration cuts to NIH research payments www.statnews.com/2025/02/10/n... See our story for @statnews.com

Each Super Bowl generates roughly $500 million in local economic activity. Now, imagine suddenly losing the equivalent of 42 Super Bowls. The new NIH 15% indirect cost cap will strip our communities of $21 billion in economic impact. #keepNIHstrong #science #episky #medsky #gobills

Get in Dorks, we are going protesting. STAND UP FOR SCIENCE. MARCH 7th 12-4pm. DC AND YOUR STATE CAPITALS. More information to come.

Here are some facts about "facilities and administrative" (F&A) costs, what we in the business call "indirects" and what Musk is calling "overhead" as he tries to convince Americans with being ok with cutting billions on dollars from medical and public health research at universities & hospitals 1/

This is the most relevant article to NIH and research cuts I’ve seen. Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !” globalnews.ca/news/9793403...

On reflection, some analysis of the Trump NIH funding cuts tonight. 1. The indirect rates are unequal. But they’re not very unequal. Harvard 69%, Wayne State 55%, Texas A&M 54%, Vanderbilt 58%. Some of this variation is justified based on cost-of-living in different places. 🧪 1/

1. Today the NIH director issued a new directive slashing overhead rates to 15%. I want to provide some context on what that means and why it matters. grants.nih.gov/grants/guide...

Indirect Costs and Trump's Attack on Independent Voices. My latest post: buttondown.com/sbagen/archi...

“It’s important to see the big picture... [The cut in indirect costs] came directly from a Project 2025 proposal that was explicitly designed to “reduce federal taxpayer subsidization of leftist agendas.” This whole piece by @sbagen.bsky.social is excellent. 🧪

🚨RED ALERT for 🧪: The Trump NIH just gashed indirect costs. This is a direct attack on universities. “Pursuant to this Supplemental Guidance, there will be a standard rate of 15% across all NIH grants for indirect costs.” 😮 Just a devastating Friday night news dump. #scicomm #academicaky

This week, #MELODEM features Dr. Sebastian Walsh presenting: "The value of a population-level lens in #dementia research: examples from prevention and treatment" Th Feb 6 @ 11a US ET. Join our distribution list for zoom specs. sites.bu.edu/melodem/cont...

Feels weird celebrating in these times, but I submitted my first R01 today. Fingers crossed, I guess?

1/ If you were taught to test for proportional hazards, talk to your teacher. The proportional hazards assumption is implausible in most #randomized and #observational studies because the hazard ratios aren't expected to be constant during the follow-up. So "testing" is futile. But there is more 👇

Jan 31-last day to enroll in the TRASE training on principles of reproducible research in aging & social science. IMO these skills and thinking are sorely lacking in most current training programs. Understanding of the importance has advanced rapidly in the past 25 years but training lags. #EpiSky

It would be fantastic if major federal institutions would acknowledge that the executive branch cannot legally unilaterally cancel or redistribute congressionally appropriated funding on ideological grounds and thus they have no legal obligation to comply with such directives

Hot off the press! 📣📣In this tutorial we illustrate available multiple imputation approaches for handling longitudinal data including when they are clustered within higher level clusters. A reproducible example with R and Stata code provided! #OpenAccess onlinelibrary.wiley.com/doi/10.1002/...

We’re a day into the second Trump presidency & public health has already taken some big hits. To get the public back on board with public health, we have to help them understand why we do what we do. So, if you work in public health, what concept do you wish more people understood?

#MELODEM, your favorite place to hash out #methodologic challenges in #dementia research, kicks off 2025 w a session ft Dr. Miguel Arce & Dr. Emily Briceño-Abreu conversing abt "Cross-national harmonization of the Harmonized Cognitive Assessment Protocol (HCAP)." Th Jan 16, 11a US ET via zoom.
