Ireland and Lithuania have much in common. Both are small, Catholic, Europhile, enjoy a tricky relationship with a larger neighbour and have cuisines heavy on potatoes. Both also left it late when it came to homosexual rights. Homosexual acts were decriminalised only in 1993 in both countries. But since then, things have diverged. Merely living without fear would be an improvement: 84% of LGBT people in Lithuania are not comfortable revealing their identity.

Where an iron curtain once split Europe, a rainbow curtain now divides the continent. In western Europe, homosexual people enjoy a quality of life better than anywhere on the planet. They are free to marry and adopt children, and are protected from discrimination in all walks of life. Things in eastern Europe are not so good. In seven EU countries, including Poland, Hungary and Romania, less than half the population agree that homosexual people should have the same rights as straight ones. civil partnerships are not offered in six EU countries, all in central and eastern Europe. Poland has introduced "LGBTz-free zones", a legally meaningless gimmick with the practical effect of declaring open season on gay people. Meanwhile, Hungary is working on a law that will ban gay couples from adopting. For gay people behind the Rainbow curtain—which covers about a quarter of the EU's population—life can be grim.

Since family law is mainly up to member states, there is little the EU can do if a member state wants to stop a lesbian marrying or a homosexual couple adopting. Where Brussels can muscle in is when the right to free movement collides with bigoted domestic law. What happens if a gay couple and their child move to a country where such relationships are not recognised? The European Commission wants to smooth out these bumps, ensuring that the link between children and their gay parents is not severed if they move to a country where gay adoption is banned. While few are affected directly, such a move has potent symbolic power. Definitions of online hate speech will be widened to include homophobic abuse, too. Towns that introduced LGBT-free zones in Poland had EU funds cut. But the main thing the EU can offer is a pulpit, hammering those leaders who refuse to treat citizens equally.

Such banging of the drum for gay rights by Brussels does come with a risk. It is a fight both sides want to have. Normally, populists rely on caricatures when taking aim at Brussels. In this case there is less need. Populist politicians will claim that the EU is doing all it can to force countries to treat gay people better. EU officials will happily plead guilty. A common complaint is that eastern Europe is expected to go through decades of social change in the space of a few years. Change can happen quickly, though. Ireland enjoyed a social revolution in less than a generation, and Malta passed a slew of legislation that helped it become the most gay-friendly country in the EU in just a few years. There are few complaints about the pace of transformation in central and eastern Europe when it comes to living standards.

With the EU cowering(退缩） beneath a second wave of covid-19 cases and in the middle of its biggest-ever recession（经济衰退）, a fight over gay rights could easily fall down the pecking order. It should not. The EU has made much of promoting "European values". Usually, these tend to mean a respect for the rule of law, which is hardly inherently European. When it comes to gay rights, however, Europe has genuinely been a pioneer. Until a gay person in Vilnius or Budapest has the same rights as one in Dublin or Madrid, European values are no such thing at all.

Dogs have been man's best friends for 30,000 years—and now scientists think they know why.

Dogs are usually not relaxed in a lab environment, but with a little petting and lots of treats, they can be trained to sit still even in an MRI (磁共振成像) scanner. That's how researchers at Hungary's ELTE University were able to get images of their brains at work.

Researcher Attila Andics said it helped them better understand the dogs' relationship with humans. "We have known for a long time that dogs and humans share similar social environment, but now our results show that dogs and humans also have similar brain mechanisms (方法；机制) to process social information," said Andics.

After training 11 dogs to stay motionless while their brains were scanned, the researchers checked their neurological (神经系统的) responses to about 200 emotionally

significant sounds, from whining and crying to playful barking and laughing. They then compared the responses from human subjects. They found great similarities. Andics said it opened new possibilities for the research.

"It establishes a foundation of a new branch of comparative neuroscience, because until now it was not possible to measure the brain activities of a non-primate and a primate (灵长类) brain in a single experiment," said Andies.

Evan Maclean, Professor in Duke University, said that the Hungarian results were an important step forward.

"We've known for a long time that dogs have a lot of behavioral similarities compared to humans. But we don't know anything or very little at least about whether some of these behaviors are represented similarly inside the brain of the dog, so this research is providing a first glimpse into whether these behavioral similarities are underlined by similar neural processes," said MacLean.

The Hungarian scientists tell ordinary dog owners to treat their dog companions as intelligent friends, not mere animals, because they evidently understand human feelings.

Tonight, our family was going out to play under the full moon.

My husband Todd and I first started going on full moon walks for ourselves, as we needed these little doses of moonlight to stay happy, though sometimes we had to hike through the forest to find a perfect spot. But after we became parents, we did this for our children. We wanted to show Sierra and Bryce that it was not necessary to travel far from home to have an adventure and learn something new, and that there was much magic in the natural world, available to all.

Once we arrived at our location, Sierra and I stood holding hands, waiting to cheer the full moon in its rising—a thin sliver of the appealing moon emerged above the ridge of the mountain afar. Soon, more of the moon came out until it turned into a brilliant orange sphere. Todd explained to Sierra and Bryce that the moon generates no light, but simply acts like a mirror, reflecting the sunlight back to us. "Does the moon's face change?" Bryce asked. I told him that the moon rotates (旋转) around the earth, but does not spin by itself, so the same side of the moon is always facing the earth. Sierra remarked that the moon looked larger and closer when it was rising. I explained that it is a visual illusion (错觉) because it is so close to the horizon that the moon magically tricks our eyes into comparing it with nearby objects, thus creating the impression of the increased size.

Much of the knowledge that I shared with the kids was learned from my parents. During my childhood, they would take me on educational adventures out in the woods, and as I later found, so did their parents. So every time I go for a full moon walk with my beloved family, I thank those wise educators who came before me.

To educate, sometimes all it takes is going outdoors and gazing up at the heavens.
