People naturally turn left

While analysing crowd movements during the COVID pandemic, researchers at the University of Navarra noticed something odd: people always, without fail, ended up moving in a counter-clockwise spiral. They’ve since spent five years investigating this behaviour pattern to find a root cause.

After running tests with toddlers, in Japan, with left-handed and left-footed people, people on their own, in groups, indoors, outdoors (etc, etc) they always got the same result. Almost everyone, everywhere, has a slight tendency to turn left. A similar bias has even been observed in fish and ants, but the real kicker is this: we still don’t know why this happens.

Across Spain, protesters have rallied around the eviction of Maricarmen, a vulnerable 87 year-old, to protest the country’s deep housing crisis. In this article, we look at how Spain’s housing model made affordable, secure housing so hard to come by. There are lessons here for the rest of Europe, as while Spain’s ongoing protests grab headlines, its crisis is anything but unique.

Looking elsewhere, we take a deep dive into the debate surrounding the EU’s decision to sanction Russian journalist Xenia Fedorova over her role in spreading Russian propaganda, and explore the reasons why Europe is so keen to boost its presence in the Arctic.

Xenia Fedorova, or how Russian propaganda turns free thinking on itself

Antoine Marie, Sciences Po; École normale supérieure (ENS) – PSL; Maxime Audinet, Institut national des langues et civilisations orientales (Inalco)

The Fedorova case is emblematic of a rhetorical method used by Russian propaganda: appealing to the targeted public’s critical thinking to convince them to disregard sources seen as “official” and “dominant.”

  • Without water, forests lose their ability to absorb CO₂

    Nicolas Martin, Inrae; Hervé Cochard, Inrae; Isabelle Maréchaux, Inrae; Julien Lamour, Centre national de la recherche scientifique (CNRS)

    To survive dry spells, trees stop the water-rich process of photosynthesis. When nature’s natural carbon capture machine grinds to a halt entire forests end up producing more CO₂ than they absorb.
