When The World Arrives At Your Border

Farmer and activist Cedric Herrou

This is the face of civil disobedience, circa 2017. Cédric Herrou, a 37-year-old farmer from southeastern France, appeared in court yesterday in Nice for having illegally helped undocumented African migrants cross the Italian-French border. "I do it because it has to be done," Le Monde quotes him as saying.


An olive and egg farmer and pro-migrant activist, Herrou was arrested in October for setting up the squatting of a disused holiday village belonging to France's state-owned railway company SNCF for a group of more than 50 migrants from Eritrea. He had already been arrested two months before that for attempting to smuggle Eritreans by car from Italy, but that case was eventually dropped. To the presiding judge's surprise yesterday, the arrests didn't stop him. "Even if you condemn me, the problem will go on," he said in court. Herrou also explained that several migrants, including three minors, were currently staying at his farm and that about 30 other minors were staying with local residents.


The prosecutor Jean-Michel Prêtre denounced what he perceived as a "PR strategy" and suggested Herrou "had wanted the trial" to push forward his political agenda, Le Figaronotes. "It's not up to the justice system to change the law," Prêtre said. "It's not up to the justice system to give diplomatic lessons to this or that country." Under French law, Herrou faces up to five years in prison and 30,000 euros ($31,500) in fines, but the prosecutor called for an eight-month suspended sentence, with driving restrictions.


The decision isn't expected until Feb. 10, but the bearded farmer already gave an idea of how he would take whatever sanction comes his way: Before entering the courtroom yesterday, he told some 300 supporters gathered outside, "What I'm doing is not a sacrifice, it is an honor." Is this Herrou's real lesson? When the world's problems show up at your doorstep, you can send a message back out to the world — even if your own country doesn't have the answers.

Forest Networks? Revisiting The Science Of Trees And Funghi "Reaching Out"

A compelling story about how forest fungal networks communicate has garnered much public interest. Is any of it true?

Over the past few years, a fascinating narrative about forests and fungi has captured the public imagination. It holds that the roots of neighboring trees can be connected by fungal filaments, forming massive underground networks that can span entire forests — a so-called wood-wide web. Through this web, the story goes, trees share carbon, water, and other nutrients, and even send chemical warnings of dangers such as insect attacks. The narrative — recounted in books, podcasts, TV series, documentaries, and news articles — has prompted some experts to rethink not only forest management but the relationships between self-interest and altruism in human society.

But is any of it true?

The three of us have studied forest fungi for our whole careers, and even we were surprised by some of the more extraordinary claims surfacing in the media about the wood-wide web. Thinking we had missed something, we thoroughly reviewed 26 field studies, including several of our own, that looked at the role fungal networks play in resource transfer in forests. What we found shows how easily confirmation bias, unchecked claims, and credulous news reporting can, over time, distort research findings beyond recognition. It should serve as a cautionary tale for scientists and journalists alike.

First, let’s be clear: Fungi do grow inside and on tree roots, forming a symbiosis called a mycorrhiza, or fungus-root. Mycorrhizae are essential for the normal growth of trees. Among other things, the fungi can take up from the soil, and transfer to the tree, nutrients that roots could not otherwise access. In return, fungi receive from the roots sugars they need to grow.

As fungal filaments spread out through forest soil, they will often, at least temporarily, physically connect the roots of two neighboring trees. The resulting system of interconnected tree roots is called a common mycorrhizal network, or CMN.
