Not enough data
John Timmer's coverage heavily leans towards scientific and technological topics, with a strong emphasis on data-driven insights. He delves into diverse subjects such as science journals, image fraud, fossil evidence, quantum computing, and FDA regulations.
As his focus is national (United States), pitches should align with US-specific developments or feature experts based in the country. Given his extensive use of data in articles and referencing press releases, he may be interested in receiving pitches that are backed by relevant statistics or research findings from reputable sources.
Pitches related to new scientific discoveries, advancements in technology within the US context, regulatory changes impacting science-focused industries like pharmaceuticals would likely resonate well with John Timmer.

Last week, just before the US started its break for the July Fourth holiday, the Nuclear Regulatory Commission (NRC) proposed a new rule that would change how it regulated exposure to radiation. The Trump administration has been pushing to restart construction of nuclear power plants in the US, and many…
One of the central features of plate tectonics is the formation of new crust at mid-ocean ridges.
One of the central features of plate tectonics is the formation of new crust at mid-ocean ridges. Part of the spreading process that drives continents apart, it was arguably the discovery of these ridges that drove widespread acceptance of plate tectonics as a theory. Thanks to decades of exploration, we now…
There are some obvious big picture issues that stand between us and useful quantum computing.
21 pts There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make enough high-quality hardware qubits to connect into the error-corrected logical qubits we need, and how we generate the states needed to perform universal computation on those logical…
If the large, rocky planet is losing helium, then we can infer what is left behind.
30 pts Most of the gas in the Universe is a mixture of hydrogen and helium. It's thought that the initial atmospheres of most planets also start out that way. However, over billions of years, as planets evolve, the composition of their atmospheres may shift. Hydrogen can react with other chemicals, and both it and…
Climate change is being driven largely by the greenhouse gases we've pumped into the atmosphere, which trap more of the Sun's energy there.

13 pts Climate change is being driven largely by the greenhouse gases we've pumped into the atmosphere, which trap more of the Sun's energy there. That added energy increases the odds of extreme events: longer, more intense heat waves and droughts, interspersed with excessive precipitation. But these sorts of events…
