Group Captain Shubhanshu Shukla made a historic return to Earth in July 2025 after completing an 18-day mission aboard the International Space Station. As pilot of Axiom Mission 4, he launched on June 25 aboard a SpaceX Crew Dragon and docked with the ISS a day later. This mission marked the first time an Indian astronaut visited the ISS, making Shukla only the second Indian in space after Rakesh Sharma.

During his time in orbit, Shukla participated in over 60 scientific experiments. These ranged from stem cell research and muscle physiology to advanced technology demonstrations. The mission involved collaboration with scientists and researchers from more than 30 countries, placing India at the forefront of international space research efforts.

Shukla’s return to Earth came with a safe splashdown in the Pacific Ocean. He was reunited with his wife and son shortly after landing, describing the emotional moment as “feeling like home.” The experience deeply moved people across the country, and his mission was widely celebrated by the public and government alike.

This mission is seen as a major milestone for India’s space journey. Shukla is expected to play a key role in India’s upcoming Gaganyaan program. His successful stint aboard the ISS has sparked new enthusiasm for space exploration and inspired a new generation of dreamers.

You might think men grow beards just for style or to show masculinity — but the real reason might actually shock you.

Recent studies suggest that facial hair, especially beards, may have evolved as a kind of natural cushion — a shock absorber for the face. According to evolutionary biologists, beards may have helped protect ancient men during physical conflict, particularly punches to the jaw. The idea is simple: facial hair adds padding, reducing the force of impact and lowering the risk of serious injury like fractures.

One experiment tested this by using fake human jaws with and without hair coverings. The results showed that bearded models absorbed more force and suffered less damage. In the rougher times of early human history, where hand-to-hand fights over territory, mates, or status were common, a bit of extra face armor could mean the difference between dominance and defeat.

So, while modern men might grow beards for fashion or identity, it turns out those whiskers may have served a more primal, practical purpose: protecting the face in a fight. Yes, your beard might just be your face’s original airbag.

Nvidia has recently reached a huge milestone by becoming the first company in the world to hit a market value of 4 trillion dollars. This means the total value of all its shares added together is more than 4 trillion. It’s a big moment not just for Nvidia, but for the entire tech world.

The company makes powerful computer chips that are used in artificial intelligence (AI), gaming, and big data centers. These chips help computers think faster and work smarter. As AI becomes more important in daily life and business, more people and companies are investing in Nvidia.

In the last few years, Nvidia's stock price has gone up very fast. It took just over two years to grow from 1 trillion to 4 trillion. This shows how much people believe in the company’s future. Investors expect Nvidia to earn a lot of money in the coming years because of the demand for AI technology.

This rise in Nvidia's value also helped the U.S. stock market reach new record levels. Many experts believe Nvidia will continue to grow as it stays a leader in the AI and tech industry. It’s a clear sign that the world sees AI as the future—and Nvidia is leading the way.
