When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

I found Jimmy Carter's Environmental Program (fittingly?) in the dumpster in the alley behind my house. "The sight of earthrise was awesome. It was also sobering. From that moment we could no longer avoid understanding that all life must share this one small planet and its limited resources."

Pamphlet of the President's Environmental Program 1979Quote from Jimmy Carter: "Ten years ago, at the dawn of the environmental decade, we landed on the moon. For the first time people could stand on the surface of another world and look at the whole earth. The sight of earthrise was awesome. It was also sobering. From that moment we could no longer avoid understanding that all life must share this one small planet and its limited resources."

After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology.

1/ Why do patients with late-stage cancer lose motivation & sink into apathy? 🔥 Our new Science paper shows chronic inflammation activates a cytokine-sensing brain circuit that lowers motivation. Huge team effort: Aelita Zhu, Sarah Starosta, Pignatelli & Janowitz labs! 🧵 🔗 doi.org/10.1126/scie...

A neuroimmune circuit mediates cancer cachexia-associated apathy

Cachexia, a severe wasting syndrome associated with inflammatory conditions, often leads to multiorgan failure and death. Patients with cachexia experience extreme fatigue, apathy, and clinical depres...

12/ This project took a *huge* team, spanning neuroscience, immunology, and cancer. Grateful to co–first authors Aelita Zhu, Sarah Starosta, co–senior authors Marco Pignatelli & Tobias Janowitz & ours labs & all our amazing collaborators including @kravitzlab.com & Pavel Osten.

About fifty years ago, NASA strapped a message in a bottle to a rocket and flung it into the deep dark It wasn’t supposed to go this far, but it did. Long past its mission, it’s still out there so far away now that a simple hello takes a day to reach it, and another day to hear if it says hello back

Special shout out this AM to NIH 🧪 grant mgmt specialists, POs, and SROs during this chaotic time - THANK YOU for caring for our grants and uploading scores/summary statements despite the unprecedented challenges you may be facing. You are science warriors and we APPRECIATE & SUPPORT YOU 🫶

I am recruiting for postdoctoral and technician positions at UCSD. If anyone with relevant skills/interests has lost funding due to the anti-DEI jihad or the NIH purge, I’m open to discussion of ways we can try to help out.

Most of these F31 applicants who had their apps pulled from review will be first time newbies to the NIH system. They are not hardened to the brutality like most of us. So heartbreaking to contemplate their disappointment and confusion and pain over the lost opportunity.

It's time to educate our neighbors about the importance of science funding. Local news papers still exist and are read by folks. Here is the op-ed I wrote for this week's "News of Orange", a local paper in Orange Co NC. Full text is on the alt-text 🧪

Science funding is key to the future of America and the health of our community

I am a Biology professor at UNC and this semester I am teaching a course called Cancer Biology to a group of juniors and seniors.  I began teaching this course 20 years ago and it’s been incredible to see and teach about the improvements in cancer treatment.  Between 1991 and 2019, the cancer death rate decreased 32%.  New treatments for breast cancer, colon cancer, and most recently melanoma have saved millions of lives—many of us know a cancer survivor.  Similar advances occurred in treating heart disease, with drugs like statins changing outcomes.  Even more exciting changes are starting to roll out:  these include the first gene therapy treatments for sickle cell disease and Type 1 diabetes.  It’s been exciting to be a small part of this—our lab helped define how signaling between cells goes wrong in colon cancer.
None of these new treatments arise in a vacuum.  All rest on decades of basic and translational research, and follow-up clinical trials, most of which is funded by our tax dollars via the National Institutes of Health (NIH).  North Carolina and especially the Triangle play an essential role in this, making science and technology key drivers of our state and regional economy.  In 2023 NIH awarded $2.28 billion (yes, with a b) in grants to NC institutions, and this helped us create more than 25,000 jobs.  Nationwide more than 400,000 jobs are supported by NIH grants, and this generates $92 billion in economic activity.  
The National Science Foundation, which funds scientific research more broadly, has a similar impact, fueling, for example advances in solar energy or helping us understand the impact of climate change on the NC coast.  NSF provided $220 million in grants to NC Institutions in 2023.  In total, UNC received $800 million in federal research funding in 2023, Duke $860 million and NC State $416 million.  This not only creates jobs directly but is also the reason …

Reminder: You can always submit a grant late and include a cover letter saying why. NIH receipt and referral may take it. Or not. If you end up missing deadline because of these Commons access issues, there is this potential save move.

guys I tried ChatGPT for drafting some summary sections in a grant application and it was just... really lame. Like vague and bland and not something that was ever going to engage a grant reviewer at 10.30pm on a Thursday night while they had a glass of red wine in their hand
