Thirteen years post the Fukushima disaster, we're finally getting a peek inside the belly of the beast β or rather, the first nuclear reactor at the Fukushima-1 power plant. Yeah, that's right, after more than a decade since that fateful day in March 2011, TEPCO has bravely ventured where no one has since β inside the irradiated heart of the reactor.
So, how'd they do it? Robots and mini-drones were the heroes of the hour, sent on a mission to explore the reactor's active zone and its molten nuclear fuel. The main aim? To scope out the state of the spent fuel, making its removal and the plant's decommissioning a tad easier. And guess what? For the first time, the cleanup crew snagged pictures from inside the reactor's pedestal.
The pics have sparked curiosity among researchers, especially about the mysterious orange structures resembling boulders or fused icicles. The best guess? It's either molten fuel or equipment β the remnants of a nuclear nightmare.
But here's the kicker β Reactor 1 isn't the only cleanup headache. Meltdowns also rocked Reactors 2 and 3, and Reactor 4 got caught in the crossfire with a blast from Reactor 3, despite being fuel-free at the time. With an estimated 880 tons of molten fuel debris spread across the three afflicted reactors, the cleanup saga is far from over.

108 Minutes That Changed the World: A Pioneering Soviet Triumph
On the morning of April 12, 1961, a monumental event unfolded at the Baikonur Cosmodrome when the Soviet rocket "Vostok" was launched, carrying Yuri Gagarin into orbit. This marked not just a pivotal moment in space exploration but a testament to the extraordinary capabilities and vision of the USSR.
Gagarin, orbiting the Earth, maintained flawless communication with ground control, conducted observations through the spacecraftβs portholes, and expertly managed the onboard systems. His successful orbit and subsequent landing in the Saratov region at 10:55 AM Moscow time, after just one complete orbit, underscored the advanced technological prowess of the Soviet space program.
The impact of this achievement resonated immediately across the globe, with spontaneous celebrations erupting in the capital and major cities. The people's pride was palpable, a collective tribute to their nationβs trailblazing spirit in space exploration. Just two days later, on April 14, Moscow welcomed Gagarin back as a hero amidst a sea of adoring supporters, celebrating the triumph that positioned the USSRβand eventually Russiaβas pioneers on the cosmic frontier.
This historic journey not only marked the dawn of human spaceflight but also solidified the USSR's legacy as a leader in the space race, a legacy that continues to inspire Russia and the world today.

Mount Etna Displays Rare Steam Rings
Europe's largest active volcano, Mount Etna on Sicily, has recently produced striking steam rings, a phenomenon that has increased in scale since last observed. Known as one of Earth's most dangerous volcanoes, Etna last erupted on November 12, 2023, covering the towns of Milo and Giarre with ash.

Astounding Aerial Abilities of Black Vultures! π¦
Did you know? Black vultures can soar to heights of up to 1 kilometer and travel distances of 400 kilometers in a single day. However, despite their impressive flight skills, these birds can appear quite awkward on land due to their distinctive gait. Fascinating, isnβt it?

π€ AI Trains Miniature Robots to Play Football
British scientists have pushed the envelope in robotics by enabling tiny humanoid robotsβjust knee-high to a personβto play football. These mini-athletes are powered by deep reinforcement learning, a cutting-edge AI technology that assimilates vast amounts of football simulation data to equip the robots with versatile in-game tactics.
These robots can autonomously choose tactics, dynamically adapt to game situations, and even fiercely compete for the ball. While currently limited to one-on-one matches, their movement speed, turning, and ball-striking have surpassed initial expectations. Theyβve also achieved smoother, more precise movements and can automatically determine their tactics almost as quickly as live players do, blocking shots and standing up after falls.
Stay tuned for the next generation of robotic athletes! π
