In just 110 days, China has achieved a remarkable feat of engineering — completing the world’s widest underwater roadway, the Jinan Huanggang Road Tunnel beneath the mighty Yellow River. Measuring 55.8 feet wide and stretching over 2 miles, the tunnel was excavated with "Shanhe", the largest tunnel boring machine ever used in the region, capable of cutting through the riverbed at a rate of 59 feet per day.

What makes this project even more impressive is its structural precision: it required over 500 reinforced pipe rings to stabilize the underwater passage. Once operational in late 2025, this six-lane tunnel will serve as a vital link between the northern and southern districts of Jinan, reducing congestion, boosting logistics, and symbolizing China's commitment to next-generation infrastructure.

This isn't just a tunnel — it’s a milestone in rapid urban connectivity built at an unprecedented pace.

Honda R&D Co., Ltd., the research division of Honda, successfully launched and vertically landed a prototype reusable rocket at its testing site in Taiki, Hokkaido, Japan.

The test vehicle stood 6.3 meters tall, weighed about 1.3 metric tons, and reached a height of 271 meters (890 feet). Most impressively, it achieved a precision landing within 37 centimeters of the designated pad after hovering for over 56 seconds.

This test was part of Honda’s long-term vision to develop low-cost, small-scale reusable launch systems that can support satellite deployment and suborbital missions.

By 2029, Honda aims to develop a rocket capable of reaching suborbital space (~100 km altitude), marking a serious entry into the private aerospace sector.

While Honda has not announced any immediate commercial plans, the test marks a significant milestone. It positions the company alongside global players like SpaceX, Blue Origin, and ISRO, showcasing the potential of traditional automakers to expand into space technology.

The successful test also underscores Honda’s ability to integrate its automotive expertise—particularly in control systems and fuel efficiency—into space applications.

Saudi Arabia is planning to build a skyscraper so tall, it would dwarf even the Empire State Building — standing at four times its height. This futuristic tower, part of the NEOM megaproject in the desert, could soar past 2 kilometers, potentially becoming the tallest man-made structure in history. Designed to anchor the “New Murabba” district, it represents the country’s boldest vision of vertical living, commerce, and tourism all stacked into one vertical metropolis.

In comparison, the Empire State Building — once the tallest in the world — measures 1,454 feet (443 meters) to its tip. The new Saudi tower, if realized, would reach over 8,000 feet, making it not just a feat of architecture but a literal city in the sky. With flying taxis and integrated smart tech rumored in the plans, this tower could redefine what a skyline truly means.

The blue whale’s heart is the largest known in the animal kingdom — so massive that a human could crawl through its arteries. At over 1,000 pounds and nearly the size of a Volkswagen Beetle, this powerful organ beats with a force strong enough to circulate 60 gallons of blood in a single pump, fueling a body that can grow over 100 feet long and weigh up to 200 tons.

Despite its size, the blue whale’s heart has an incredible adaptation: during deep dives, its heartbeat slows to just 2 beats per minute to conserve oxygen. This biological marvel reflects the astonishing scale and efficiency of the blue whale’s circulatory system — a reminder of the ocean’s unmatched giants and the extremes life can reach in the deep.
