📣 Our latest Arena Paper is out, on the decline of labour journalism: 'The invisibles': Why we need to talk about work. While it is possible to trace good, regular, in-depth reporting about labour, these stories are now rare; labour desks are, in effect, extinct.  🧵 👇 [1/3]
A stack of papers with a coffee stain, with the title 'The invisibles': Why we need to talk about work. Overlaid is the Arena and Arena Papers logos, as well as a subtitle: Mapping the structural forces of labour journalism's decline - and what we can do about it.

💙 The Dataharvest 2026 Illustration Gallery is live! Thanks to our live illustrator Pieter Fannes who brings our conference to life every year by visualising our journalist community's work in beautiful, imaginative ways. Visit the gallery at the link in bio, and Pieter's work at pieterfannes.com
An illustration depicting a session at Dataharvest 2026, where two women present their investigation 'From Onlyfans to Onlyscams'. One woman sits at a desk and one stands behind it with a microphone, and a selection of their slides are projected behind them on the wall, depicting a wolf engaging a young woman in cam work, with subtitles such as "women only get 5%" and "sexting done by pimp (or bots)"An illustration depicting a session where two female journalists describe impersonating other people online to infiltrate a rapist network. The two women appear 'inside' snakes, holding notebooks and pens, taking notes as they chat to the snakes around them. Bubbles containing their advice for safety when undercover appear around them: 'define your persona', 'stick to your rules: no encouraging', and 'check your mental health'.

Thrilled to be included in this article about this year's Dataharvest! "Stefan Candea and Yossi Bartal presented one of the year’s most revealing investigations. When 300GB of data from the Israeli Ministry of Justice was leaked, few took notice. It took Bartal’s particular profile to act on it".

💡 Ignoring #AI “would be like ignoring the internet at the turn of this century—or electricity in the previous one.” At #Dataharvest 2026, we're choosing to educate instead of avoid the hard questions around the ethics, possibilities and practicalities of AI in #journalism. Link 👇🔗
