A new study challenges the idea that a baby's sex is pure chance. Harvard researchers studied pregnancies among US nurses. They found families with more kids had higher chances of all boys or all girls. Maternal age also links to baby's gender. Genes may influence baby's gender, but experts urge caution. Family choices and biological factors play a role.

An asteroid named 2025 ME92 is set to fly past Earth on July 31. It will maintain a safe distance of 3.19 million kilometers. NASA and ISRO are monitoring this near-Earth object. Although not hazardous, its trajectory is under observation. ISRO plans to collaborate internationally on planetary defense. This event highlights the importance of tracking asteroids and protecting our planet.

NASA's X-59 supersonic jet, dubbed the "son of Concorde," has completed low-speed taxi tests, advancing toward its first flight. Engineered with "quiet supersonic technology," it aims to minimize sonic booms, potentially revolutionizing air travel by significantly reducing flight times between major cities. This progress could pave the way for commercial supersonic flight over land.
