China has just shattered speed records with a full-scale maglev prototype reaching 621 mph (1,000 km/h) — all inside a vacuum tube built for near-zero resistance.

Using high-temperature superconductors, the train levitates without touching the track, moving silently and cleanly with no fossil fuels. The result? A Beijing–Shanghai trip in just 1.5 hours, beating planes on speed and emissions. More importantly, China just proved long-distance vacuum tube travel is viable—a huge leap toward commercial reality.

This isn’t just the world’s fastest train. It’s a blueprint for the future of travel.

Hành trang của con chỉ có niềm tin của mẹ và cuốn số hộ nghèo

Nguyễn Nhật Tường, 22 tuổi, tân kỹ sư ngành Công nghệ chế tạo máy, khiến nhiều người rơi nước mắt khi chia sẻ về bố mẹ trong lễ tốt nghiệp ngày 14/6. Bạn chia sẻ: "Hành trang của con chỉ có niềm tin của mẹ và cuốn số hộ nghèo. Con cũng không phải là đứa trẻ giỏi vào thời điểm ấy. Và hôm nay, trên tay con là tấm bằng xuất sắc.

Con chỉ mong sau này mẹ sẽ luôn an tâm với những quyết định của con và có nhiều niềm tin vào con.

Gửi ba, dù ở một nơi nào đó rất xa, con mong ba chứng kiến được khoảnh khắc này của con. Khoảnh khắc con lớn lên và có thể tự lo cho bản thân, mong ba sẽ yên tâm và tự hào về con".

Không phải ai cũng bắt đầu với điều kiện tốt, nhưng ai cũng có quyền mơ một giấc mơ lớn.

Hành trình của Tường là minh chứng rằng: có những tấm bằng không chỉ được viết bằng mực, mà được chắt ra từ nước mắt, sự hy sinh và lòng tin bền bỉ của cả một gia đình.

A new study suggests Earth’s water may not have come from comets or asteroid impacts after all—it may have been here from the very beginning.

Researchers from the University of Oxford and the UK’s synchrotron science facility analyzed rare meteorites called enstatite chondrites (ECs), which closely resemble the materials that built Earth 4.55 billion years ago. Using a powerful X-ray technique (XANES spectroscopy), they found surprisingly high levels of hydrogen embedded deep within these ancient space rocks.

Crucially, this hydrogen was located within pristine regions of the meteorites, not in areas that could be contaminated after falling to Earth. The findings suggest that hydrogen from ECs could have naturally bonded with oxygen in early Earth’s rocks, forming water without any need for cosmic “delivery.”

This challenges the long-held theory that water arrived later through impacts by icy comets or hydrated asteroids. Instead, water may have been a built-in feature of the planet-forming process itself. By showing that Earth’s ingredients already included enough hydrogen for ocean formation, the study reframes our understanding of how life-supporting environments emerge on rocky planets.

It’s a discovery that simplifies one of science’s biggest questions: where did Earth’s water come from? Maybe... it was always here.
