Recently in France, TV viewers were treated to a remarkable exchange between France’s former education minister, Luc Ferry, and Daniel Cohn-Bendit, aka “Dany Le Rouge”, one of the leading lights of May 68 and a former MEP for the Greens.

Daniel Cohn-Bendit: “The Baltic countries are in NATO.”

Luc Ferry: “Not at the moment, it depends which ones.”

Daniel Cohn-Bendit: “The three Baltic countries are in NATO.”

Luc Ferry (now irritated): “Not all the Baltic countries…”

The conversation soon descended into a Monty Python-like sketch that would have had any high school history teacher tearing out their hair, the two politicians spatting over whether the Baltics included 3, 4 or 6 countries – confusing the Baltics and the Balkans.

It was a good illustration of how ill-informed and, sometimes disdainful, the West can be toward what it regards as “Eastern Europe” – itself a contested concept. But increasingly, the countries from that region are calling on their bigger neighbours to take them more seriously, starting in the domain of foreign policy with Russia.

Ukrainian scholar Viktoriia Lapa argues that political leaders in Lithuania, Estonia, Latvia, Poland and the Czech Republic have long had a more refined understanding of Russia than France or Germany. According to Lapa, it’s time we listened to them and stopped “westsplaining”.

As spring beacons, there and elsewhere in the Northern Hemisphere will be in thaw – the Russians call this season “rasputitsa”, literally, “the time without roads”. The question of why ice can be both slippery and sticky, however, is as solid as ever for physicists. Much further down South, atmospheric scientist Sergi González Herrero warns Antarctica is melting rapidly, with temperatures during heatwaves soaring 30C or 40C higher than the average.

The hype around AI continues, with many claiming that it is now capable of empathy. “Not so fast,” says Catrin Misselhorn, a philosopher of science.

The EU should stop ‘westsplaining’ and listen to its smaller eastern members – they saw the Ukraine war coming

Lithuania doesn’t often set the agenda, yet it has been warning that Russia would invade Ukraine since 2008.

The sticking point: why physicists are still struggling to understand ice’s capacity to adhere and become slippery

Philippe Brunet, Université Paris Cité; Pierre-Brice Bintein, Université Paris Cité

How can the same material, ice, have diametrically different physical properties - sticking and sliding?

Climate change is speeding up in Antarctica

The sub-zero area of Antarctica has shrunk by over 100km since the 1950s.

‘Empathetic’ AI has more to do with psychopathy than emotional intelligence - but that doesn’t mean we can treat machines cruelly

Catrin Misselhorn, Georg-August-Universität Göttingen

Artificial Intelligence’s capacity to mimic and identify emotions is worlds away from the human one to feel.

The middle-aged brain changes a lot – and it’s key to understanding dementia

Middle age could be a period when we can detect early risk factors of future cognitive decline.

The problem with shaming people for Auschwitz selfies

We analysed hundreds of selfies and found some people were shamed more than others.

Why do children laugh? It’s not always because they’re happy

Carlo Valerio Bellieni, Università di Siena

Laughter is one of the healthiest things a child can do, but it means very different things at different stages of brain development.
