Scientists have long relied on chemical traces locked inside ancient rocks to piece together the story of early life. Fossils from the deepest reaches of Earth’s history are rare, often fragmentary and difficult to interpret. Isotopes, by contrast, can survive for billions of years. Among the most informative are those linked to nitrogen, an element…

Innovation often begins with solving problems that others consider impossible. For Dr Robert Sola Okojie, a Nigerian-born engineer and inventor, that pursuit has led to a career spanning more than two decades at Nasa and groundbreaking contributions to space technology. After 21 years at Nasa and securing 21 US patents, he was inducted into the…

From hundreds of kilometres above Earth, a national celebration looked very different. While crowds gathered across the United States for the country’s 250th anniversary, astronauts aboard the International Space Station watched the evening lights spread across the planet below.
