The first paper of my graduate school career has been published!! Drake Phelps and I, along with our co-authors Giuliano Ferrero, Jamie Dewitt, and Jeff Yoder review how #PFAS impact innate #immune function across species. Please give it a read! doi.org/10.1080/1547691X.202…

People can spread this version of hantavirus to each other. What makes Andes virus special? sciencenews.org/article/ande…

The recent U.S. FDA characterization of baby formula as “safe” is entirely misleading. In the FDA dataset, about two-thirds of the infant formulas tested had detectable PFAS. The highest levels were found in soy-based formula samples, especially powder soy-based formulas. These detections were mainly driven by PFBA, with some soy powder samples containing around 30-34 ppt. @bennettpeer @Nathan_Donley theguardian.com/us-news/2026…

FYI - People are confusing "hantavirus has a long incubation period" with "covid was contagious before symptoms showed up." Incubating ≠ contagious. Andes virus is not an upper-airway, high-shedding respiratory virus. It evolved for a very different survival strategy.

I think we can all agree the government telling scientists what to publish is catastrophically bad. When I say they're annihilating American science, this is what I mean.

Hi, medical toxicologist/ER doctor here 👋 here’s what you need to know about medetomidine in the illicit opioid supply

The hill I will die on - we have to rethink graduate training. “Scientists are trained for a world where data speaks for itself. Where misinformation moves slowly. Where scientific expertise naturally rises above noise. That world is gone.” sciencepolitics.org/2026/03/…

In the late 1950s, a drug called thalidomide was widely prescribed in Europe and Australia as a highly effective treatment for morning sickness in pregnant women. The manufacturer assured doctors that the drug was completely safe. However, thalidomide is a chiral molecule, meaning it exists in two mirror-image forms. While one form successfully cured nausea, the other was highly teratogenic. The drug crossed the placental barrier and interfered with the development of fetal blood vessels, leading to a global catastrophe. Over 10,000 babies around the world were born with severe limb deformities, often missing their arms and legs entirely. The United States largely avoided this tragedy thanks to an FDA inspector named Frances Kelsey, who famously stonewalled the drug's approval by demanding more safety data, despite facing massive pressure from the manufacturer. This averted disaster directly resulted in the passage of the 1962 Kefauver-Harris Amendment, which fundamentally defined the modern regulatory framework for the FDA. Prior to this amendment, the regulatory bar was essentially just proving that a drug wouldn't acutely kill people (kind of like the current bar for most recreational peptides). The 1962 amendment introduced a much higher standard: pharmaceutical companies were now legally required to conduct controlled clinical trials to prove that their drugs were not only safe, but also actively effective for their intended use. The gap between the old standard and this new requirement was massive. In fact, roughly two-thirds of the drugs that had previously passed the 1938 safety requirements ended up failing the new 1962 efficacy bar. This historical context is often cited by public health experts today when defending the FDA's grueling, multi-phase clinical trial requirements against critics who argue for faster drug approvals or unregulated access to experimental compounds.

Excited to share our new paper! 🐝🎉Chronic exposure to the insecticide sulfoxaflor alters gene expression in bumblebee ovaries, suppresses reproduction, and changes behavior—ultimately impairing colony function. Take a look: sciencedirect.com/science/ar…

Columbia and NYU researchers tracked 11,000 people for 20 years. Urine tests before. Urine tests after. When they switched to clean water, their risk of dying from cancer and heart disease dropped 50%. Here's what was in their water the entire time: 🧵

A good reminder that regulations are written in blood.

RT @Feisty_Waters: No AI, I don’t want you to summarize everything. I want to read things and think about them with my own brain.

100% correct.

Doctors and parents should be aware that the medical textbook description of a "bright red measles rash" is based on white skin. On brown or black skin, the measles rash can be much harder to see. It may appear as darker, dusky or purple patches rather than bright red spots.

A common misconception I am seeing in the replies is that antibiotic resistance isn’t about your body becoming resistant. It’s the bacteria that become resistant. Even if you personally use antibiotics responsibly, or have never used antibiotics ever , if those resistant bacteria infect you, the standard antibiotics won't work on you too. That is why it is a community problem and needs urgent awareness programs for both patients and healthcare professionals

“No one expected this.” Jane Hoppin and fellow scientists were surprised to find TFA in years-old samples, raising new questions about PFAS and environmental health. Learn more. ➡️: ncst.at/hYy950Y7JK4
