I am begging all news reporters who cover the "tylenol and vaccines cause autism" press conference PLEASE lead your reporting and headlines with facts and caveat that these assertions were not backed by any scientific evidence but rather the whims and feelings on unqualified non-scientists

Oh hey it's Friday let's be excited about SCIENCE still happening!

Super pleased to be part of this new synthesis on Rift Valley Fever epidemiology, by a global team led by Melinda Rostal, describing an emerging understanding of the disease's varied regimes across Africa. doi.org/10.1016/j.la...
Rift Valley fever epidemiology: shifting the paradigm and rethinking research priorities Rift Valley fever (RVF), a zoonotic mosquito-borne viral disease with erratic occurrence and complex epidemiology, results in substantial costs to veterinary and public health and national economies. Since 1985, RVF virus (RVFV) epidemiology has focused on epidemics triggered by flood-induced emergence of transovarially infected mosquitoes, following an interepidemic period during which RVFV persists primarily in floodwater Aedes spp mosquito eggs, with potential for low-level interepidemic circulation. In this Personal View, we challenge this classic framework of RVFV epidemiology, presenting instead a spectrum of RVFV dynamics ranging from epidemic to hyperendemic. We present the case for RVFV being maintained in a variable reservoir system of livestock, wildlife, and mosquitoes, with or without transovarial transmission. We highlight that sufficient evidence supports a shift in the paradigm of RVF epidemiology to embrace a more nuanced understanding of the spectrum of RVFV dynamics and call for more research into understanding the drivers of RVFV dynamics in hyperendemic areas.

GREAT piece by @petridishes.bsky.social on why Dr Ladapo ended school vaccine requirements in his state

"The state of Florida, understandably, said: 'Enough. This needs to stop. We have decided that there are too many children, and we can let some of them go.'"

The state’s elimination of vaccine mandates is a courageous first step toward decluttering itself of any excess kids.

Today we gathered to honor Officer David Rose. He was a man of quiet integrity. He loved food, motorcycles, and most of all, his family.

He answered the call. Our call. And gave his life to protect the community he served

We will be forever grateful. Rest in peace.

Silence = Death Is Real Now More Than Ever, but Words Aren’t Enough—Action Is Needed! Joseph Cherabie Clinical Infectious Diseases, ciaf243, https://doi.org/10.1093/cid/ciaf243 Published: 03 July 2025 TO THE EDITOR—Thanks to Meyerowitz and Schwartz [1] for their viewpoint article, which highlights all the jarring changes that President Trump and his administration have pushed through since they started dismantling elements of the US Department of Health and Human Services. I agree with the authors that we must “urgently find our voices and gather our strength to defend” the principles we believe in as a field. But there is one major point that the authors neglected to mention: We will get nowhere if our advocacy fails to rise above publishing strongly worded statements in scientific journals. By responding only in this way, we have become an echo chamber of our own creation. To change the hearts and minds of the populace, we need to replace beautiful speeches with meaningful action. That means learning from the group that inspired this article's title―ACT UP, the AIDS Coalition To Unleash Power―and showing the true impact of these budget cuts to our field: People will die. So here is what you can do: 1. Determine your risk tolerance and act accordingly. It's important to consider what “fighting back” means for you as an individual. If you have privilege in your position, use it to stand up for those who lack stable funding, such as early career folks and post docs. Speak to local news outlets, local governments, state governments, governors, affinity groups, and congress. Organize advocacy calling hours. Join a local protest. Support local organizations. And if you truly don't have the time or bandwidth to spare, donate money to legal organizations that are fighting for our patients and jobs in court. There are so many ways to help, but do something beyond simply saying that you stand for something. 2. Community disruption as advocacy. We must disrupt busine… When the Government Attacks Free Expression, the Pen is a Mighty Sword Free Eric A Meyerowitz , Ilan S Schwartz Clinical Infectious Diseases, ciaf244, https://doi.org/10.1093/cid/ciaf244 Published: 03 July 2025 TO THE EDITOR—We wholeheartedly agree with Cherabie [1] that in these perilous times, words are not enough: infectious diseases professionals must be prepared to organize and act to defend science, patients, and public health. We hoped that our call to resistance [2] would spur urgent discourse in the face of the Trump administration's draconian attacks on principles, institutions, and people that we hold dear, and we are grateful to Cherabie for proposing actions, which we endorse completely. We continue to emphasize the importance of standing up and speaking out against harmful actions of powerful people and institutions, particularly as the Trump administration wages war on free expression. The attacks surround us [3]. Noncitizen residents and visa holders are being stripped of their legal protections and dignity, detained in deplorable conditions, and/or deported for peacefully protesting government policies [4]. Social media accounts of foreign students and visa applicants are being scoured by the Department of Homeland Security for dissenting views to justify rejections [5], and academics have been reportedly denied entry for unflattering comments about the Trump administration uncovered on their personal electronic devices [6]. Universities are being threatened and billions of dollars in federal grant funding withheld in efforts to control what is taught and by whom [7]. Even the First Amendment rights of medical journals are under direct threat, with several publications, including the New England Journal of Medicine and Chest, receiving letters from a federal prosecutor inquiring about bias in editorial processes in a thinly veiled attempt at intimidation against free discourse [8]. In this context, we believe speech is an essential action in…

Few go into pediatrics because it’s hard & pays < other specialties

International trainees fill spots but w immigration changes that’s going to get much harder.

BUB (Big Ugly Bill) eliminates CHGME which pays for >50% of pediatric trainees.

Not sure who is going to take care of our kids.

one of the world's top cancer scientists, who works for Harvard, is at risk of deportation to Russia where she might be killed for criticizing Putin, because she allegedly failed to disclose carrying frog embryos at the border. it's upending American medical research: prospect.org/health/2025-...
Until now. For instance, the cancer scientist Kseniia Petrova, a Russian immigrant who worked at Harvard’s renowned Kirschner Lab, has been in a Louisiana ICE prison for two months now, and is facing deportation to Russia because she allegedly lied to a border control officer about carrying frog embryos for research purposes. Not only is this likely false—she told NBC News that she did tell the officers the truth—but the usual penalty for such a piddling violation is a $500 fine, knocked down to $50 for a first offense. Instead, ICE revoked her J-1 visa and threw her in prison pending a hearing to deport her back to Russia, where she might easily end up in prison or dead for criticizing the Putin regime. Petrova is not just any cancer scientist—she is perhaps the world’s top expert on analyzing the images produced by a new cutting-edge, ultra-specialized microscope that is being developed to diagnose cancer cases. Leon Peshkin, Petrova’s manager, told NBC that the task “requires a unique set of skills because you have to both be able to work as an embryologist and do applied math, modeling, data analysis and bioinformatics—all in one package.” Nobody else in the lab could do what she does, he added.
