Angela Merkel, Last Act For Europe's Super Middle Manager

"The nation-state on its own has no future... "


Angela Merkel's apparently ominous declaration in late May was actually part of what might be the strongest vote of confidence in recent memory to ensure the future of the European Union. After years of touting austerity and protecting national fiscal sovereignty, the German Chancellor has suddenly teamed up with French President Emmanuel Macron to launch a 500-billion-euro European Union recovery fund that mutualizes members' debt for the first time. It's a fiscal U-turn justified by the risks of the "deepest recession since the Second World War."

No doubt that risk is very real, and Merkel is now urging swift adoption at the upcoming EU summit in mid-July — while also reminding the so-called Frugal Four (Austria, Sweden, Denmark and the Netherlands) — that populist extremists would pounce on a divided EU.

But the German leader changing her stance overnight simultaneously tells us plenty about the precariousness of the situation. Dutch author Joris Luyendijk described the claims about populism as half-truths, as "refusing mutualized debt will fuel populism in the south. But by adopting mutualized debt you are going to fuel populism in the north."

And it gets worse. Adding to the deepening of the perennial north-south rift, which has festered since the Greek debt crisis, there is also the cultural and political east-west divide. More recent entries like Poland and Hungary risk undermining the union since EU membership has failed to deliver on all the envisioned post-Communist economic potential.

And in the middle of all of this sits Germany, which coincidentally embarks today on its six-month rotating EU Council presidency. Europe's largest economy, contributing a quarter of the Union's GDP, is still wrestling with its 20th-century history and what it means to be a nation. There is an inherent paradox in Merkel dismissing the nation-state as much of the world looks to her country to rescue the European Union. If she pulls it off, it would be a fitting final act of a political career successfully managing a world of paradox.

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.
