The history of Gaza dates back more than 5000 years. In antiquity, it was a key port on the Mediterranean coast. Assyrians, Ancient Greeks, Romans, Byzantines and the Ottomans have all left their mark on this small territory. This rich history is seen by Palestinians as central to their identity. Amid the death and destruction of the war, the BBC’s Middle East Correspondent Yolande Knell meets the Palestinians who’ve desperately tried to save what remains of Gaza’s past.

Over the past year, BBC Eye has documented life in Ukraine’s second largest city, Kharkiv, helping to capture the deeply personal stories of those living under the continuing shadow of war. Just 30 kilometres from the Russian border, this Russian-speaking city has sustained some of the heaviest attacks of the war.

Reporter Albina Kovalyova follows the stories of people who have nevertheless chosen to continue to live in Kharkiv. One, a writer from the Czech Republic who unexpectedly found love during a visit to this frontline city last year – and who uprooted her life in Prague to move to Ukraine to be with him. He’s an artist from Kharkiv, Konstantin Zorkin, who describes his belief in the transformative power of art and love.

These personal stories of love and life are intercut with the violence Russia continues to unleash on this city of over a million people. And they are set against a shifting geopolitical backdrop, of ultimatums and recriminations and talks, as all the while the attacks on Kharkiv and Ukraine continue.

Rising sea levels and a worldwide shortage of buildable land make the prospect of floating buildings and infrastructure more beneficial than ever. MAST is an architectural firm based in the southern harbour of Copenhagen in Denmark. Surrounded by shipbuilders and workshops, the MAST studio, run by two young passionate architects, devises and builds houses, community centres, saunas and whole neighbourhoods on water.

While many of their projects can be seen on the waters of Copenhagen, the team is inspired by the long tradition of waterborne dwellings across the world and are currently working on constructions in Thailand, the Maldives, the USA , India and Portugal.

Architecture critic and author Jonathan Glancey is invited to Copenhagen to see the studio in action and to travel out by boat to look at some of the completed projects.

Deep inside the Colombian Amazon hi-tech submarines are being built. When it comes to making the cocaine trade more profitable, there’s nothing narco-traffickers aren’t willing to try. Some of the solutions they’re reportedly employing sound like something out of the American TV series Breaking Bad: GPS-trackers, remotely operated submarines and recruiting highly specialised scientists. Reporter José Carlos Cueto of BBC Mundo has been investigating the new trends and technologies used by cartels in Colombia and abroad.

Labubu dolls, the elf-like plush toys from the Chinese toy maker Pop Mart, seem to have taken the world by storm. Singer Rihanna had one clipped to her bag, influencer Kim Kardashian shared her collection of 10 dolls on Instagram, and former England football captain Sir David Beckham also shared a photo of a Labubu, given to him by his daughter. So, what’s behind this craze? Fan Wang reports from Singapore.

From the US to the Middle East, sand and dust storms have recently swept across many parts of the world, colouring the skies and leaving people with breathing problems. These storms traditionally originate in vast deserts. However, scientists believe that climate change means more people could be affected - with desertification and melting glaciers, exposing more dust. Maria Zaccaro, a BBC journalist reporting for the Global Journalism Science and Climate team, finds out more.

Mumbai in India is one of the most densely populated cities in the world - and it’s also the perfect habitat for leopards. BBC Marathi recently posted a video on their YouTube channel, showing these majestic wild cats strolling down residential streets and even entering people’s homes.
