Is college worth it? On average, college graduates outearned high school graduates by almost $87,000 over an initial 15-year period even after accounting for the cost of college.

Another conservation success story!
A giant fish called the arapaima is the focus of a conservation success story in the Brazilian Amazon.

ALT A giant fish called the arapaima is the focus of a conservation success story in the Brazilian Amazon. Scientists have worked with local villages to protect the commercially valuable fish from poachers while allowing villagers to profit from a sustainable arapaima harvest. The project has spurred development and led to the protection of some 150,000 km2 of tropical forest. Photo: Michael Dantas/AFP via Getty Images

The collapse of trust in science is going to go down in history as one of the most sad, bizarre, and destructive social contagions of modern times.
We fed billions, cured diseases and powered nations - yet people ran toward conspiracies instead.

Wow! It’s already hard to keep up with the literature and separate the good from the bad. This is going to make it impossible!
More than 7 million research papers were published in 2025.
That number is about to explode.
Think about all of the research agents and AI writing tools that were developed last year: @OpenAI’s Prism, @elicitorg, @FutureHouseSF, @k_dense_ai, etc. What happens as adoption of those tools inevitably increases? What happens to volume when the average researcher becomes fluent in @claudeai Code?
Scientific infrastructure and peer review was designed for a different world than the one we are entering.
Peer review is in crisis.

💼🌿 Many measures that help insects — less mowing, less intensification, less pressure on landscapes — require doing less, not more.
If you want a candid look at the tension between biodiversity and economics, this episode with Roel van Klink (@UniHalle) delivers.

🌼 Biodiversity loss can feel overwhelming — but there are concrete steps individuals can take.
In #InsideBiodiversity, Dr Roel van Klink (@UniHalle & #iDiv) shares practical actions that can help insects:
🌱 Plant native species
🪨 Avoid stone gardens
✂️ Reduce mowing
🥩 Rethink and reduce animal‑based food consumption
💛 Support biodiversity‑friendly public land management
🐜 Small actions matter, especially when many people take them.

We've all had a paper or two that feels like this. Maybe the scientific community should start a process for reviewing journals and handling editors (0 to 5 stars) to make transparent who is doing their job and who is not.

So true! I like this paper by Aczel et al. in PNAS discussing the future of peer-review. Ideas include getting rid of it altogether.

Here's a story in the French newspaper, Le Monde, about the controversies surrounding van Klink's work on insects.

Pesticides changed. CO₂ dilutes plant nutrients. Climate shifts species ranges. But researchers still do not know how these drivers combine to shape insect trends.
A clear, grounded explanation from Roel van Klink (@UniHalle & #iDiv) on #InsideBiodiversity.

🪲 Researchers have been monitoring insects for decades — but throughout that entire period, ecosystems were already heavily shaped by human activity.
That means researchers still don’t know what “natural” insect abundance looked like before major human impacts.
In this new episode of #InsideBiodiversity, entomologist Roel van Klink (@UniHalle and #iDiv) explains why this matters, why insects are so astonishingly diverse, and what long‑term data can tell us.
If you want a clear, nuanced introduction to insect trends, this conversation is a great place to start.

5/6 BioTime does not account for the single largest contributor to biodiversity decline -- habitat loss. Not one study in that dataset shows how 43% of Earth's land surface that used to be forested, but has been converted to agriculture, has influenced biodiversity.

6/6 When the dataset you are using to assess diversity change does not consider the dominant driver of diversity loss, and relies on studies where biodiversity can only go up (e.g., recovery, succession), then it not representative of how humans are altering biodiverity on Earth.
