From the Indigenous doctor balancing traditional and western medicine to a father risking death to provide for his family in Gaza, these are some of the people whose determination and bravery stood out

In 2012, Adana Omágua Kambeba travelled 4,000km (2,500 miles) from her home in Manaus, in the Brazilian Amazon, to take up a coveted place to study medicine at the Federal University of Minas Gerais in south-east Brazil. She became the first among her people, the Kambeba, or Omágua, to graduate in the field, still largely dominated by white elites. According to the 2022 census, Indigenous people represented 0.1% of those who graduated in medicine in Brazil.

It was our first joint family Christmas, and I watched fearfully as my mum walked into the kitchen she had once called hers. The next 48 hours were full of surprises

There are still moments I pinch myself: when, over the remnants of turkey and red wine, my divorced parents regale us all with an in-joke from their previous life. When, on the pre-lunch walk, my dad and stepdad stroll in lockstep and talk about finance and even feelings, occasionally. When we’ve all exchanged gifts, and the most thoughtful gifts are not between husband and wife or parent and child, but ones the divorced and remarried couples have given each other.

We’ve been doing this for 25 years now, this joint family Christmas, complete with step-parents, parents and siblings. But every so often, I remember how weird it all once felt. The first time, when I was 11 years old, I watched fearfully as, on Christmas Eve, my mum walked into the kitchen she once called hers. Despite her initial efforts to pretend otherwise, it was clear she still knew where everything lived – and that the next 48 hours would be easier if she admitted it.

Did you watch KPop Demon Hunters? Have you listened to Rosalía? And do you know who ‘fedora guy’ is? If you answered yes to all these, this is the quiz for you

The understated lead in this year’s creepy festive drama is ideal for the whispered dread it drips with. Be warned, though: it verges on horror – young kids may well be terrified

It is a truth universally acknowledged that a family gathered around a roaring yuletide screen must be in want of a ghost story. Since 1968, therefore (or a couple of years earlier, depending on whether you count the precursor Whistle and I’ll Come to You, directed by Jonathan Miller – and who am I to tell you nay?), the BBC has sporadically provided one in the form of the Ghost Story for Christmas series. These days, it is an annual event, delivered as a half-hour adaptation by Mark Gatiss of a spooky short story from the Victorian or Edwardian archives, which gives us some shivery distraction and provides some lovely actors with gainful employment of a not too onerous kind in the lead-up to Christmas.

To begin, the recent reboot of the series comprised mostly adaptations of Gatiss’s greatest love, MR James, but there has also, as befits the co-creator of Sherlock, been one by Arthur Conan Doyle (Lot No 249). Then, last year, it was derived from a tale by E Nesbit-yes-that-E-Nesbit from the days before she was pulling in royalties from The Railway Children, and the Psammead wasn’t even a glint in Edith’s eye.

From Copenhagen’s cycle lanes and Vienna’s shared parks to Barcelona and London’s unfulfilled potential, better living is close at hand

The angry rumble of a speeding SUV. The metallic smog of backlogged traffic. The aching heat of sun-dried neighbourhoods baking in an oven of concrete and asphalt.

For most people, the mundane threats that plague our environments are likely to annoy more than they spark dread. But for scientists who know just how dangerous our surroundings can be, the burden of knowledge weighs heavy each day. Across Europe, environmental risks cause 18% of deaths from cardiovascular disease and 10% of deaths from cancer. Traffic crashes in the EU kill five times more people than murders.

In this week’s newsletter: Pushing Buttons readers on their favourite games of the year, from Death Stranding 2 and Arc Raiders to Ghost of Yōtei and more

Happy holidays, Pushing Buttons readers! Once again, we are approaching the cherished time of year between Christmas and New Year when we might actually have the time to play some video games. I hope Santa brought you something new to play, instead of taking one look at all the unplayed games in your Steam library and putting you straight on the naughty list.

Over the past few weeks you have been sending in your favourite games of the year. I maintain that you readers have excellent taste: there’s crossover with our own Guardian games of the year list, but also plenty here that I haven’t played myself. Thank you to everyone who sent in a recommendation, and I hope you find yet another game to add to your pile of shame among the following suggestions. I’ll be back next week with a year-in-review issue – in the meantime, go enjoy yourselves!

Fourteen countries, including Britain, Canada and Germany, have condemned the Israeli security cabinet’s approval of 19 new settlements in the occupied West Bank, saying they violate international law and risk fuelling instability.

Israel approved a proposal last Sunday for the new Jewish settlements, which brings the recent total to 69, according to the far-right finance minister, Bezalel Smotrich.

A car with a “Happy Chanukah” sign has been firebombed in a Melbourne suburb in the early hours of Christmas morning.

The suspected antisemitic incident comes less than two weeks after the terror attack that targeted Jews celebrating the holiday of Hanukah at Sydney’s Bondi beach and claimed 15 lives.
