What does it take to make something which has never existed on Earth before? The search for element 120 on the periodic table has begun at the Lawrence Berkeley National Laboratory in California. Cosmologist Andrew Pontzen, who is used to studying the processes of creation, visits the 88-inch Cyclotron facility at Berkeley, where the next new element may be created very soon. To uncover what motivates scientists to pursue something that is possibly only produced in the violent explosions of stars he speaks with the scientists trying it now, the scientists who last made an element at Berkeley 50 years ago, and a historian of the fraught history of element discovery. The answer is not as straight forward as he suspected.

In September 2025 a wave of anti-government protests swept through Indonesia. Bali, however, remained free from demonstrations.

As a result, many Balinese people have become conditioned to avoid confrontation and suppress negative opinions, especially concerning the tourism sector. Tri Wahyuni of BBC Indonesian has looked into Bali's relationship with tourism and its own history.

In 1867, the US government bought Alaska from Russia for $7.2 million dollars. At the time, critics questioned the value of purchasing such an inhospitable and remote territory. Yet today, due to its abundance of natural resources, America’s largest state has proved to be a significant investment. BBC foreign correspondent Anna Holligan travels to Alaska to report on the increasing China-Russia-US tension in the region. Supported by Russia, through fishing, shipping and military exercises, China has a growing presence in the Bering Sea, which separates mainland Russia from the US by 55 miles at its narrowest point. As Anna visits the largest Coast Guard base in the world on Alaska’s Kodiak Island, she asks why is China seeking to expand their influence in one of the most dangerous and volatile seas in the world?
