EPA Transparency Proposal, Tick Milking. Nov 15, 2019, Part 1

This week, a House Committee held a hearing to review an Environmental Protection Agency proposal called ‘Strengthening Transparency in Regulatory Science.’ The proposal would require researchers to disclose underlying data —which could include private medical and health information—for any scientific studies that the agency would use in determining environmental regulations. Science reporter Lisa Friedman from the New York Times discusses how this proposal could be used to weaken regulations and discount certain scientific studies. Plus, epidemiologist Joshua Wallach talks about how the proposal could affect researchers who conduct long-term epidemiological studies.

We reached out to the EPA for comment and they provided a statement that says:

“Science transparency does not weaken science, quite the contrary. By requiring transparency, scientists will be required to publish hypothesis and experimental data for other scientists to review and discuss, requiring the science to withstand skepticism and peer review.”

Ticks are masters of breaking down the defenses of their host organism to get a blood meal. They use anesthetics to numb the skin, anticoagulants to keep the blood flowing, and keep the host’s immune system from recognizing them as invaders and kicking them out. And the key to understanding this is in the tick’s saliva. Biochemist and microbiologist Seemay Chou discusses how she milks the saliva from ticks to study what compounds play key parts in these chemical tricks. She also talks about how ticks are able to control the microbes in their saliva.
