    The Crazy Carnival Ride Soviet Turntable Procedure That Gave Us the First Corrective Eye Surgery

    The eyes, they say, are the windows to the soul. More practically, they are our windows to the world, humans being one of many visually-dependent species on the planet. But they are also fragile windows, susceptible to all sorts of injuries, diseases, and disorders. Worldwide, over 2 billion people - nearly a third of the world’s population - suffer from some sort of visual impairment, ranging from mild glaucoma and cataracts to complete blindness. Of these, 88.4 million suffer from mild, easily correctable refractive errors such as nearsightedness, farsightedness, and astigmatism. For much of history, the only solution to such impairments was corrective lenses, but more recent years have seen the rise of advanced surgical corrective technology such as LASIK. Thanks to such safe, quick, and relatively painless and inexpensive procedures, thousands of people are able to enjoy perfect vision without the hassle of glasses or contact lenses. But no technology appears fully-formed overnight, and LASIK and its relatives owe their existence to a bizarre procedure developed in 1970s Soviet Russia which involved an assembly-line team of surgeons, diamond scalpels, and a rotating operating table that looked more like a carnival ride than a piece of medical equipment. This is the story of Radial Keratotomy, the world’s first successful corrective eye surgery.

    The Horrifying World of Mind-Control Creatures

    In the 2013 video game The Last of Us and its 2023 TV adaptation, humanity is overrun by a mutant parasitic fungus called Cordyceps, which disfigures its victims and takes over their minds, turning them into violent, unthinking walking mushrooms called clickers. But this horrifying premise is hardly unique; indeed, the motif of infection and assimilation by an alien parasite crops up time and time again in popular fiction, from the 1950s novels The Puppet Masters and The Body Snatchers by Robert Heinlein and Jack Finney and their numerous screen adaptations to the 1998 film The Faculty and classic episodes of The X-Files, Star Trek: the Next Generation, The Outer Limits, and Futurama. And no wonder: horror fiction often reflects universal anxieties, and parasites have been an unwelcome part of the human experience since the dawn of time. From the tapeworms and hookworms that infect our guts to the filarial worms that cause elephantiasis to the single-celled protozoa that cause malaria, sleeping sickness, river blindness and other horrible diseases, these biological infiltrators have been - and still are - responsible for a great deal of human suffering the world over. And while the mind-hijacking parasites of popular fiction may seem like gross exaggerations created for the sake of chills and thrills, this is not the case, for such creatures are horrifyingly real. For example, Cordyceps from The Last of Us is based on an actual parasitic fungus of the same name that infects ants and other small insects, hijacking their minds and bodies and turning them into mindless slaves with one single purpose: to spread their new master’s spores far and wide. Indeed, such devious puppet masters are remarkably common in the natural world, being found in nearly every habitat and family of life - including our very own bodies. This is the story of the real-life zombie makers, the most horrifying - and fascinating - creatures on earth.

    Hollywood vs Reality: What Actually Happened During Apollo 13?

    “Houston, we’ve had a problem. We’ve had a Main B Bus undervolt.” These words, spoken by astronaut Jim Lovell on April 13, 1970, signalled the start of one of NASA’s greatest crises. Apollo 13, the third American lunar landing mission, had suffered an onboard explosion, knocking out vital systems and placing the lives of the three astronauts aboard - Jim Lovell, Fred Haise, and Jack Swigert - in grave danger. Over the next four and a half days, thousands of engineers and technicians back on earth battled one crisis after another to keep the crippled spacecraft running and bring the astronauts safely back home. Their heroic efforts paid off when, on April 17, the Command Module Aquarius splashed down in the South Pacific Ocean and astronauts Lovell, Haise, and Swigert were brought aboard the aircraft carrier USS Iwo Jima - safe and sound. The saga of Apollo 13 has been described as a “successful failure” and “NASA’s finest hour”, and was famously dramatized in the acclaimed 1995 film starring Tom Hanks, Bill Paxton, and Kevin Bacon. But while the film is praised for its historic and technical accuracy, it by necessity takes certain liberties for the sake of drama - for example, shortening Lovell’s rather passive real-life declaration to the far more urgent “Houston, we have a problem.” But what else did the film get right and wrong, and what actually caused the Apollo 13 disaster? Let’s find out as we take a deep dive into one of the greatest dramas in the history of manned spaceflight.

    Out of the Frying Pan, Into the Fire: The Extraordinary Saga of the Unsinkable Nevada

    At 9:00 in the morning on July 1, 1946, Major Harold Wood, bombardier of the B-29 Superfortress Dave’s Dream, peered through his bombsight at a massive fleet of warships gathered below. As the crosshairs fell over his target, he released his weapon, and the pilot, Major Woodrow Swancutt, pulled the aircraft into a sharp turn. Seconds later a blinding flash filled the air as history’s fourth atomic bomb detonated over the turquoise waters of the Pacific. But this was not some alternate timeline where the nascent Cold War suddenly went hot, but rather an elaborate test dubbed Able, part of a larger series of nuclear experiments called Operation Crossroads carried out at Bikini Atoll in the Marshall Islands. And while the target fleet included several former Axis ships including the Japanese battleship Nagato and the German heavy cruiser Prinz Eugen, the vast majority were American, a motley array of obsolete battleships, cruisers, destroyers, submarines, landing craft, and various auxiliary vessels. And at the very centre of the assembly, painted bright orange to serve as an aiming point, was a truly remarkable vessel: the battleship USS Nevada. A revolutionary design when she entered service in 1916, Nevada was present at Pearl Harbour on the morning of December 7, 1941 when the surprise attack by the Imperial Japanese Navy marked the ascendancy of the aircraft carrier over the battleship. And now, at the end of her career, she bore witness to another technological revolution: the dawning of the atomic age. This is the remarkable story of the USS Nevada, a ship that served through one of the most eventful periods in the history of naval warfare.
