The past week has seen significant developments in various fields, from neuroscience to gaming and international relations. In India, scientists have made a groundbreaking discovery in mapping the human brain, while in the world of gaming, Pokémon Go celebrated its 10th anniversary. Meanwhile, Gibraltar marked a new era with the removal of its 118-year-old border controls with Spain.

A team of scientists at the Sudha Gopalakrishnan Brain Centre at the Indian Institute of Technology, Madras (IIT-M), has created what they describe as the world's most detailed three-dimensional atlas of the human brainstem at cellular resolution. This digital map allows scientists to travel seamlessly from MRI scans to the cellular level, filling one of neuroscience's biggest gaps. The human brain contains approximately 86 billion neurons, and pathologists diagnosing disorders such as Alzheimer's disease typically inspect only a handful of tissue samples.

Pokémon Go, the mobile app that uses GPS and augmented reality to let players find and catch virtual monsters in real-world locations, has celebrated its 10th anniversary. With over a billion downloads across iOS and Android devices, the game has millions of players logging in each day. Michael Steranka, vice president of product at the game's publisher Scopely, says the Pokémon Go experience has always been about bringing people together.

Zhang Zhidong, a 39-year-old Chinese national, has been accused of being Mexico's "fentanyl king." According to the US Department of Justice, Zhang established a supply chain for the deadly drug fentanyl, shipping ingredients from Chinese factories to laboratories in Mexico. He was arrested in Mexico in 2024 but made a dramatic escape before being recaptured.

US Senator Mitch McConnell has released a statement regarding his health, saying he will not be returning to the Senate "quite yet" after suffering from a fall and "a mild case of pneumonia." The 84-year-old Kentucky Republican was hospitalized in mid-June, sparking speculation about his health.

Gibraltar, a British Overseas Territory, has removed its 118-year-old border controls with Spain. The border, which was previously a point of contention, has been a significant obstacle for commuters and travelers. Shilpi Chotrani, who commutes from Spain to Gibraltar every day, welcomes the change, saying, "The fact that there is a border between us is ridiculous. I don't think a fence should separate people from one place and another."

• Who: Indian scientists, Pokémon Go players, Zhang Zhidong, US Senator Mitch McConnell, Gibraltar residents
• What: Creation of a 3D brain atlas, Pokémon Go's 10th anniversary, Zhang Zhidong's arrest, Mitch McConnell's health update, removal of Gibraltar's border controls
• When: This week
• Where: India, worldwide (Pokémon Go), Mexico, US, Gibraltar, Spain

As scientists continue to map the human brain, the implications for neuroscience and medicine are vast. Meanwhile, the Pokémon Go phenomenon shows no signs of slowing down, and the removal of Gibraltar's border controls marks a new era in international relations. As for Zhang Zhidong, his trial is pending, and the world waits to see the outcome.
