On this celebratory day of women and girls in science, let’s reflect that the US National Science Foundation has put the words β€œwomen” and β€œfemale” (but not β€œmen” and β€œmale”) on the list of forbidden words that will get your grant slated for the reject bin.

Send Google feedback! (Directions below, its easy!) If enough people voice their outrage, it can influence corporate policy.

I didn't mean to imply aren't reaching tipping points, rather that stating we are "out of time" suggests an inevitability to mitigating climate change impacts. Nancy Knowlton has highlighted how "doom and gloom" science can lead to self-fulfilling inaction. I prefer to focus on actions we can take.

Coral bleaching surveys in Bonaire from 2016-2023 show that last year had the most widespread bleaching and related coral colony mortality. While this is disheartening, focusing on increasing local reef resilience can help buy time to address global climate change. πŸͺΈπŸ’ͺ

Estimating global article processing charges paid to six publishers for open access between 2019 and 2023 This study presents estimates of the global expenditure on article processing charges (APCs) paid to six publishers for open access between 2019 and 2023. APCs are fees charged for publishing in some ...

🚨 Preprint! We combine our recent open dataset of #APC prices with the article counts per journal-year from #OpenAlex to estimate how much the academic community has paid in APCs over the last 5 years.
