On this day in 1951, JD Salinger's iconic novel, The Catcher in the Rye, was published. The book introduced the world to the unforgettable teenage protagonist, Holden Caulfield.
Here is all that took place on this day across the world.
The first atomic bomb exploded
One of most important events of the 20th Century took place on July 16, 1945. The first atomic bomb was successfully tested by the United States in Alamogordo, New Mexico. And with this, the world entered the nuclear age.
The bomb, nicknamed 'The Gadget,' used plutonium-239 and was detonated at 5:29 am. The explosion created a blinding flash, a fireball that reached temperatures hotter than the surface of the sun and a mushroom cloud that rose over seven miles (11 kilometres) into the sky. It produced an energy equivalent of about 21 kilotons of TNT.

Led by physicist J Robert Oppenheimer, the Manhattan Project brought together some of the greatest scientific minds of the time, including Enrico Fermi, Richard Feynman and Niels Bohr. The successful test confirmed that nuclear fission could be weaponised, changing the course of history.
After witnessing the explosion, Oppenheimer famously quoted the Bhagavad Gita, 'Now I am become Death, the destroyer of worlds.'
Just three weeks later, the US dropped atomic bombs on Hiroshima on August 6 and Nagasaki on August 9, leading to Japan's surrender and the end of World War II. The Trinity test not only marked the dawn of nuclear warfare but also triggered decades of arms races, Cold War tensions and ethical debates about the use of such destructive technology.

Catcher in the Rye published
JD Salinger's only full-length novel, The Catcher in the Rye, was published by Little, Brown and Company on this day in 1951. With the launch of the book, the world was introduced to the unforgettable teenage protagonist, Holden Caulfield.
Set in post-World War II America, the novel follows Holden over the course of three days in New York City after being expelled from prep school. Disillusioned by the 'phoniness' of the adult world and struggling with grief over the death of his younger brother, Holden narrates his journey in a raw, confessional tone that was both controversial and groundbreaking at the time.

While initial reviews were mixed, the book quickly gained popularity among young readers and became a bestseller. Its honest portrayal of teenage alienation, mental health, and rebellion struck a chord with postwar youth and sparked widespread debate.
Salinger, who became famously reclusive after the novel's publication, never allowed a film adaptation and published little afterward. Yet his lone novel became a literary icon and has sold over 65 million copies worldwide.

China was quick to test the nuclear bomb. India missed vital landmarks
Innocent, since the name didn't convey its unifocal military purpose. The world entered the nuclear age with a military purpose, and its impact on 6 and 9 August 1945 over Hiroshima and Nagasaki are historical landmarks that will not be erased anytime soon. Reams have been written about the Manhattan Project and its impact. The ghastly use of the bomb against Japan has also been dissected threadbare. What has been relegated to dusty shelves and nerdy researchers, however, is the official report on the programme. It's unambiguously called Atomic Energy for Military Purposes . The site couldn't have been chosen because of the irony in its name. In the days of Spanish expansion into the New World, this must have certainly been a deadly route to take, but that was centuries before America's wartime quest for the world's most potent weapon. And it was tested under the codename 'Trinity'. A multi-billion-dollar initiative that involved scores of enterprises, institutions, and scientists of various disciplines working under strict military supervision, it was innocently labelled 'Manhattan Project'. In an era of multiple strifes across continents, an anniversary quietly slipped under the radar of world watchers. Eighty years ago, an explosion ushered in a new age of combat, weapons, tactics, and technology. At 5:29 am local time on 16 July 1945, the United States tested the world's first atomic bomb in the desolate desert of New Mexico in an area called Jornada del Muerto—Spanish for 'Dead Man's Road'. Among the most extraordinary aspects of the report is that it was made public on 12 August 1945, even before the radioactive clouds had lifted from Hiroshima and Nagasaki. Princeton University physicist Henry DeWolf Smyth penned the report. Within the community that contributed to making the nuclear fission device a success, the Smyth Report was the working paper on how the Manhattan Project was to be discussed. It is patently clear that the US was working on a long-term nuclear perspective. Also read: What India can learn from Israel about atmanirbharta in defence India's nuclear age The American military approach is a far cry from how India viewed the arrival of the nuclear era. Although its nuclear journey is extraordinary among formerly colonised nations, India missed vital landmarks along the way. In July 1945, India already had a nuclear research programme at the Tata Institute of Fundamental Research (TIFR), established months before Washington's Trinity test. Within a year of Independence, the country also had an Atomic Energy Commission, and in less than a decade, it had commissioned Asia's first nuclear reactor, APSARA, at Trombay. India was light years ahead of any other Asian country. In the 1950s, China was largely dependent on its larger ideological ally, the Soviet Union. It entered the nuclear age with a sole purpose, based on Chairman Mao's dictum, 'Power flows from the barrel of a gun.' The simple formulation offered Beijing both short-term benefits and dividends in the long run, too. It is now obvious that the possession of weapons of mass destruction will not invite military intervention in an era of mass hypocrisy. Iran and Iraq, which didn't possess nuclear arsenals, were attacked, while North Korea, which did, wasn't. Hypocrisy and discrimination are obviously kosher in today's world order. India, however, approached the nuclear era from the perspective of 'peaceful utilisation' to harness unlimited energy and enter the club of rapidly developing countries. It officially launched a three-stage nuclear programme with an indigenous research and development project. But eight decades after TIFR initiated its research programme, India remains light years away from its early energy vision. And it has also missed the bus to power by failing to test a bomb on time. Even as it was obvious that the world was entering a discriminatory nuclear regime that no amount of third-worldism or non-alignment mantras could prevent, India persisted in keeping company with those who had nothing to lose. China, on the other hand, tested its first device in 1964, as soon as it could put the nuclear bolts together. It joined the nuclear club and subsequently became a permanent member of the United Nations Security Council. By the time India tested the bomb in 1974, the doors of the nuclear elite club had closed.

When war got weird: 10 military experiments that seem straight out of sci-fi
War has a funny way of turning wild ideas into serious government projects. In the chaos of World War II and the paranoia of the Cold War, military minds across the globe cooked up experiments that sound less like national defense and more like fever dreams. Think remote-viewing psychics, napalm-strapped bats, pain rays, and yes, even a surgically wired CIA spy cat, code-named 'Acoustikitty,' who was supposed to eavesdrop on Soviet agents but promptly wandered off. These weren't jokes, they were fully funded, sometimes top-secret missions with real budgets and even weirder intentions. Most of these plans fizzled out, tripped up by science, common sense, or the sheer unpredictability of, say, cats. But they offer a fascinating, and often hilarious, look into what happens when military strategy meets sci-fi imagination. So if you've ever wondered what it looks like when serious defense programs go completely off the rails, you're in the right place. Let's reimagine it. Acoustikitty : CIA tried to recruit cats, they refused to take orders In the mid-1960s, the CIA launched a curious and ambitious project known as "Acoustikitty," aiming to use wired and microphoned cats to covertly eavesdrop on open-air conversations between foreign agents and their Soviet contacts. The plan involved implanting a microphone in the cat's ear, a transmitter under its skin, and an antenna woven into its fur, allowing it to inconspicuously capture sensitive conversations in public places like parks. Despite the technology functioning as intended, the fundamental flaw lay in the cat's unpredictable behavior, true to feline nature, it couldn't be trained to follow specific commands or approach intended targets reliably. After several unsuccessful tests, the project was ultimately abandoned in 1967 without ever seeing operational use. Still, the story of Acoustikitty remains one of the most bizarre and enduring legends of Cold War espionage. Project Stargate : Psychic soldiers for intel Project Stargate was a Cold War-era US intelligence effort to explore the potential military use of psychic phenomena, especially remote viewing, the claimed ability to perceive distant or unseen targets without physical presence. Sparked by reports that the Soviet Union was heavily investing in psychic research, the CIA feared falling behind in this unconventional domain. Throughout the 1970s to 1990s, the program evolved under various codenames like SCANATE, GONDOLA WISH, and GRILL FLAME, eventually becoming known as Stargate. Supporters of Project Stargate cite cases where remote viewers allegedly identified a crashed Soviet aircraft in Africa and described hidden facilities later verified by traditional intelligence. However, critics argue these successes were overstated, noting that remote viewing often produced vague or inaccurate information and that results could not be reliably replicated under controlled conditions, casting doubt on the program's scientific validity. By 1995, it was declassified and terminated after a review found it failed to produce consistently reliable intelligence. The Gay Bomb: Chemical to 'turn' enemies In 1994, a US military lab at Wright-Patterson Air Force Base proposed developing a non-lethal chemical weapon designed to disrupt enemy morale by inducing homosexual behavior among troops using a potent aphrodisiac. The idea was part of a $7.5 million funding request aimed at researching chemicals that could impair enemy discipline and cohesion without causing physical harm. Although the "gay bomb" proposal was ultimately rejected, it resurfaced years later when the document was disclosed through a Freedom of Information request. The watchdog group Sunshine Project publicized the bizarre and controversial plan, which highlighted the extremes explored in psychological warfare during that era. Avrocar: Real-life flying saucer attempt The VZ-9AV Avrocar was a Cold War-era experimental aircraft designed to function as a high-speed, stealthy flying vehicle. Developed in the 1950s with a projected budget of $3.16 million (around $26 million today), it aimed to combine vertical takeoff and landing capabilities with advanced maneuverability. Despite its ambitious goals, the Avrocar failed to deliver in testing. It could only achieve brief hovers just above the ground and proved unstable in flight. Ultimately, the project was deemed unfeasible and was canceled before reaching operational use. Bat Bombs: Explosive bats for warfare In an unusual World War II proposal that sounds like science fiction, a quirky American inventor suggested using bats as miniature bombers. The plan involved capturing one million bats from Texas caves, attaching small napalm charges to them, and packing them into bomb casings designed to release them mid-air over Japanese cities. Once released, the bats would instinctively roost in the wooden structures common throughout Japan at the time. A timed ignition system would then detonate the incendiaries, causing widespread fires and destruction. Though never fully implemented, the concept highlights the extreme and imaginative lengths considered in wartime strategy. Project Iceworm: Missiles hidden under ice Project Iceworm was an ambitious Cold War plan to build a vast network of tunnels covering 52,000 square miles beneath Greenland's ice, about three times the size of Denmark. The design included trenches spaced four miles apart to house 600 mobile nuclear missiles, along with facilities to support 11,000 soldiers living underground, prepared for a rapid strike if necessary. A 1960 top-secret US Army report praised Greenland as an ideal location, just 3,000 miles from Moscow and strategically positioned for both offensive and second-strike capabilities. The mobility and concealment of the missiles beneath the ice were intended to prevent detection and ensure retaliation in the event of a Soviet nuclear attack. Edgewood experiments: Drugs tested on troops Between 1950 and 1975, approximately 6,720 US service members participated in chemical exposure experiments at the Edgewood Arsenal in Maryland. These tests involved 254 different chemicals and were primarily intended to study their effects on humans, evaluate protective gear, and assess how military personnel might respond to chemical warfare agents. Although no current tests can definitively confirm such past exposures, a thorough medical history and physical exam can help assess potential health risks. Participants may experience long-term psychological effects from the trauma of being used as test subjects, and concerned veterans are encouraged to consult healthcare providers for evaluation and support. Pain Ray : Heat weapon for crowd control The "Pain Ray," officially known as the Active Denial System (ADS), is a non-lethal weapon developed by the US military for crowd control and perimeter defense. It works by emitting a focused beam of millimeter-wave radiation that penetrates the outer layer of skin, producing an intense burning sensation without causing permanent damage. The beam heats the skin to around 130°F (54°C), triggering an instinctive pain response that causes individuals to quickly move away from the targeted area. Designed as a safer alternative to rubber bullets or tear gas, the Pain Ray has been tested in various scenarios but has seen limited deployment due to concerns about safety, public perception, and ethical implications. Critics argue that while it may not cause lasting harm, the psychological and potential long-term effects of such a weapon remain poorly understood. Despite this, the ADS represents a significant advancement in non-lethal crowd control technology. Camel Corps: Military camels in America The Camel Corps was a mid-19th-century US military experiment aimed at using camels as pack animals in the arid regions of the American Southwest. Initiated by Secretary of War Jefferson Davis in the 1850s, the program involved importing camels from the Middle East to test their effectiveness in desert conditions. Housed at Camp Verde, Texas, the camels proved to be strong, resilient, and well-suited for transporting supplies over long distances. Despite their success in field trials, the project was eventually abandoned due to the Civil War, lack of institutional support, and soldiers' preference for traditional animals like horses and mules. Peacekeeper Trains: Nukes launched from trains Peacekeeper Trains were a Cold War-era US military concept designed to make nuclear missile launches more survivable by placing them on mobile rail platforms. The idea was to load Peacekeeper intercontinental ballistic missiles (ICBMs) onto specially designed train cars that could travel across the national rail network, making their location unpredictable and reducing their vulnerability to a first-strike attack. By constantly moving or being deployed to remote tracks, these trains would ensure a credible second-strike capability. Although the system was tested and proven feasible, the program was never fully deployed due to high costs, logistical challenges, and arms reduction treaties. (The article uses AI generated images)

Coldwater creek and cancer risk explained by Harvard experts: Why this small stream in the US linked to cancer
Image: Istock Coldwater Creek, a stream winding through north St. Louis County, Missouri, is getting global attention. Turns out, this peaceful-looking waterway has a dark past. Due to radioactive waste dumped nearby during the World War II Manhattan Project (the one that made atomic bombs), the creek has been quietly soaking up toxic leftovers for decades. So what went wrong? Back in the 1940s, uranium waste from bomb-making was poorly stored around Lambert Airport. Over time, it made its way into Coldwater Creek—through runoff, careless dumping, and just plain neglect. That waste included stuff like thorium-230, a radioactive byproduct that sticks around forever. For most of the 20th century, the problem was ignored. Only in the 1990s did the US Army Corps of Engineers start cleaning things up, and it might not be fully done until 2038 (yes, seriously). What does Harvard say? A major Harvard study just dropped in JAMA Network Open (July 2025), and it's not good news. Researchers followed over 4,000 folks from the St. Louis Baby Tooth study—kids from the 1950s–70s who lived nearby and donated teeth to test for nuclear fallout. By linking those records to self-reported health issues, the study found that kids who grew up within 1 km of Coldwater Creek were 44% more likely to develop any kind of cancer later in life. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo But that's just the beginning. The odds shot up even more for radiosensitive cancers—think thyroid cancer, leukemia, breast cancer, and bone cancer. For thyroid cancer alone, the risk was 5 times higher in people who lived closest to the creek as kids. Participants who lived within 1 kilometer of Coldwater Creek during childhood showed a 44% higher odds (OR = 1.44; 95% CI, 0.96–2.14) of developing any form of cancer compared to those living more than 20 kilometers away, though this result bordered on statistical significance. The association was stronger for radiosensitive cancers—those linked scientifically to radiation exposure with an odds ratio of 1.85 (95% CI, 1.21–2.81) for those living closest to the creek versus the furthest. For thyroid cancer, the risk was particularly elevated (OR = 5.00; 95% CI, 1.23–20.32) Harvard epidemiologists, led by Prof. Marc Weisskopf, emphasized the broader implications of exposure to low-level radioactive waste from nuclear projects, warning that similar risks could emerge as nuclear power and weapons programs expand worldwide What cancers are we talking about? Thyroid cancer Leukemia Brain tumors Bone cancer Lung cancer Even federal agencies like the US Agency for Toxic Substances and Disease Registry are backing this up. They say anyone who lived or played near the creek from the 1960s to the 1990s could face higher cancer risks. The takeaway? The closer you lived to Coldwater Creek—and the longer you were there—the higher your chances of developing cancer. It's a textbook case of radiation exposure risks, and experts are warning this isn't just Missouri's problem.
