From Pregnancy Brain Changes to AI Exam: A Science News Roundup

This news roundup covers various recent developments in science: a study on brain reorganization during pregnancy, a global AI challenge to evaluate expert-level AI, Europe's Ariane 6 launch after a software glitch, and a major NASA contract awarded to Intuitive Machines for navigation services.

A recent study conducted extensive brain scans to map how a woman's brain changes throughout pregnancy, from conception to two years postpartum. These changes, some fleeting and others enduring, were documented over 26 scans, illuminating new insights into neurological adaptations during motherhood.

In technology news, experts have launched a global initiative called 'Humanity's Last Exam' to challenge AI systems with the toughest questions. Organized by the Center for AI Safety and startup Scale AI, the project aims to assess the advancements in AI capabilities over time.

Meanwhile, Arianespace has announced plans for the second mission of Europe's Ariane 6 launcher later this year. This follows the identification of a fixable software fault that affected the inaugural launch, which still completed a series of successful trials.

In the space exploration sector, Intuitive Machines has secured a $4.82 billion contract from NASA to provide navigation and communication services for missions in the near space region. Following the announcement, the company's shares saw a significant rise, reflecting investor confidence in their capabilities.
