Johannesburg's air quality has never really been measured systematically. Like many other cities across the globe, scientists have battled to develop cost-effective monitoring systems that provide accurate real-time data on air pollution. This is all about to change, thanks to some home-grown tech and the power of AI.

Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals or plants existed, stromatolites breathed the first molecules of oxygen into Earth's atmosphere. Now, in a study published in Current Biology, researchers say they may also hold insights into how complex life began.

For the first time, scientists have used a modern cell therapy called CAR-T to treat a patient with three different life-threatening autoimmune diseases that had resisted years of treatment. The patient, who once required daily blood infusions, has been in remission without needing additional treatment for a year since the CAR-T therapy. The case report, published in Med, suggests that CAR-T therapies can help treat complex and severe autoimmune diseases.

Earth’s nights are steadily getting brighter overall, but the changes vary dramatically by region. Rapid urban growth is lighting up countries like China and India, while parts of Europe are dimming due to energy-saving efforts and new lighting technologies. The most detailed satellite analysis yet shows these shifts happening faster and more unevenly than expected. Even global trends can mask sharp local contrasts, from war-related blackouts to deliberate reductions in light pollution.

Bestselling author, filmmaker, and actor Andrew McCarthy has a new book out, Who Needs Friends: An Unscientific Examination of Male Friendship Across America. The book is inspired by a blunt question from McCarthy's son: "You don't really have any friends, do you, Dad?". This realization prompts McCarthy to embark on a 10,000-mile solo road trip [...]
