When healthcare feels overwhelming, look for one concrete thing you can do.
Right now, the Department of Education has opened a public comment period on a proposed rule that would remove nursing from the “professional degree” classification.
That sounds technical. It isn’t.
If this change goes through, nurses and advanced practice providers could lose access to certain federal loan programs that make advanced training financially possible. That affects who can afford to become a nurse practitioner. It affects who stays in the workforce. It affects access to care.
As a reconstructive microsurgeon, I cannot care for the volume of women I serve without the nurses and nurse practitioners on my team. They are not assistants. They are licensed, credentialed professionals practicing at the highest level of their training. They are the backbone of American healthcare.
If you care about access to safe, high quality care, this matters.
The public comment period is open and closes on March 2nd.
Here is how to leave a comment. It takes five minutes:
1. Go to regulations.gov
2. Type into search “reimagining and improving student education”
3. Click “Submit a Formal Comment”
4. Write a short statement. It can be simple. For example:
“I support recognizing nursing as a professional degree. Limiting access to federal loan programs will worsen workforce shortages and reduce access to care.”
5. Enter your information and click submit
You do not need to be a doctor or a nurse to comment. You just need to care.
Small actions matter. Words matter. Please take a few minutes to support recognizing nursing for what it is: a profession.

Fixed it:
--> last year, the U.S. sold more educational services to the rest of the world than it sold in natural gas and coal **combined**
--> every $1 of research funded by NIH generates $2.56 in economic activity
--> more than 1.1M foreign students come to the U.S. each year to study and they contributed over $43 billion to the U.S. economy in foreign currency balances
--> students who came to the U.S. to study founded 55% of America’s 582 start-up companies worth at least $1 billion
--> cutting health research in Texas will cause a loss of 3,698 jobs and cost the economy $856M
--> The University of Alabama is the largest employer in the state
--> shortage of trained occ/env docs set to cost CA $1B

Nothing will kill more children than the ongoing decimation of CDC, NIH, and USAID work to lift vaccine uptake in the US and world.
Child survival rose 75% in the last 50 years. Vaccines account for 40% of that. Measles vax alone was 60% of the benefit. thelancet.com/journals/lance…

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis or other (non-LCH) histiocytic sarcomas cases.
I'm trying to understand non-surgical chemo and targeted therapy options, new pathology markers to better diagnose subtypes/treatments, and any data on progression in pediatric patients. Please feel free to share – I’m trying to cast a wide net due to the rarity of this condition and how little is known.
People can contact me directly at my first name (as written in my profile) at octant.bio.
this website shows you how many jobs NIH funding creates for your state along with the overall economic activity generated

Disruptions to the NIH impact more than just science; they will hit all Americans in our wallets. I spoke yesterday with @beckyfogel from @KUTNews
about the important role NIH-funded research plays in the economy. 🧵 1/n

Looks like NIH grant review panels have been suspended temporarily. Because it takes time to coordinate and schedule a multi-layered grant panel review from experts across the country, what seems like a short delay in review of funding applications could be the difference between survival and shuttering for many valuable research efforts.
I started my academic research lab a year before the erratic first Trump presidency and vividly remember the uncertainty of those times. The folks starting their labs now during second term are facing similar challenges. The situation is even more precarious for more established labs that don’t have stable university startup funds remaining and require external funding to continue to pay students, postdocs, & research staff to stay open.
This situation highlights that diversification of funding sources for science is good, including for the basic science that sparks so much innovation. This could mean broadening research efforts in other sectors (private for-profit or non-profit R&D).
The NIH may be the largest public funder of biomedical research in the world but over-dependence on a single sector so sensitive to political winds is bad. We need nuance and creativity in how to generate value that ensures science-driven progress. Many of us in the private sector are thinking about how to grow the pie and sustain research efforts. Our scientific ecosystem needs to be much more resilient.
If you’re an academic researcher worried about your fate, there is a pretty big world out there and a lot of ways to contribute your scientific expertise to advance solutions for humanity. You can invent them too. And if you’re a private entity, you can start to decrease dependence on publicly funded academic research for upstream discovery by expanding impactful basic science activities strategically and sharing more of the outputs openly.
Hope this message of agency resonates with those searching for solutions and a place for their energy.

“If you can’t fly, run; if you can’t run, walk; if you can’t walk, crawl; but by all means keep moving.” – Martin Luther King Jr.
Inspired by his words, we push the boundaries of exploration, moving forward for the benefit of humanity.

Teabags release billions of microplastics into our tea beverages.
A recent study found that commercially available teabags made from nylon, polypropylene, and cellulose release billions of micro- and nano-plastics into a single cup of tea.
• Polypropylene teabags released 1.20 billion particles/mL
• Cellulose teabags released ~135 million particles/mL
• Nylon teabags released 8 million particles/mL
In lab experiments, researchers exposed human intestinal cells to microplastic particles and found that different types of plastic interacted with different cell types. Polypropylene particles were absorbed by mucus-producing cells, while cellulose particles were absorbed by two types of mucus-producing cells. Nylon particles, however, were taken up by cells that help maintain the gut's protective barrier but don’t produce mucus.
These findings suggest that different types of plastics interact uniquely with gut cells, potentially affecting gut health in distinct ways. While the long-term effects of micro- and nanoplastic exposure remain unclear, it’s evident that these particles are entering our bodies through multiple sources.
You might consider switching to loose-leaf tea to reduce exposure if you're a tea drinker.

Post 1: 🎉 Excited to share our publication in JCI! Our study dives into the development of pathogenic autoreactive CD4 T cells, with a focus on impaired TCR signaling in autoimmune arthritis. We uncovered how endogenous retroviruses (i.e., MMTV Sags) disrupt peripheral tolerance and promote the activation of autoreactive T cells in the SKG mouse model of rheumatoid arthritis.
This work wouldn’t have been possible without the incredible contributions of @em_immuno , @yimmieg , Art Weiss, and the Ashouri Lab members. I am deeply grateful for their expertise, collaboration, and dedication to uncovering the mechanisms driving autoimmune disease.
📄 Read the full article here: pubmed.ncbi.nlm.nih.gov/3958…
🧬 Highlights:
We identified a highly arthritogenic subset of naive CD4+ T cells expressing Sag-reactive TCR-Vβ chains.
Peripheral antigen encounters revealed impaired tolerogenic responses in SKG cells compared to WT cells.
Antiretroviral treatments targeting MMTV disrupted the progression of arthritis, providing potential therapeutic insights.
Check it out and let us know your thoughts!
