Olympics over 120 years
The olympic games have been a showcase of the highest levels of sporting ability and athleticismfor over 120 years. but they have also seen their share of controversy, most notably in the form of doping scandals and even tragedies like the 1972 games in munich. at the same time, they have also been home to many bizarre and unexpected events. today, we take a look at 10 of them number 10. the early olympics had all kinds of events that do not exist today, like tug-of-war at the 1908 games in london. three of the teams were from great britain and all three were made up exclusively of members ofthe police. one from liverpool, one from the met, and one from the city of london. in addition, there were two national teams from the usa and sweden.the americans faced Liverpool in the quarterfinals and lost almost immediately. They complained to officials that their opponents were using illegal shoes as big as ferries on the North River with steel heels and steel cleated steel caps on the heels and steel cleats in the front of the soles, while inches of spikes protruded from the soles. This, of course, sounded like a violation of the rules, as prepared boots or shoes with protruding nails were prohibited, but liverpool police insisted that the boots were standard equipment that they wore to work the Americans' protest was dismissed, and the Liverpool team took the silver medal in the marathon with number nine, the driver. Unfortunately, cheating has always been a problem at the Olympics, but while modern cheaters usually try to find new drugs to fool the tests, athletes in the past were a bit more creative in their chicanery long-distance runner Fred Laws, who competed in the 1904 Olympic marathon in St. Louis. Halfway through the race, Laws developed cramps, so his manager picked him up in his car and drove him the next 11 miles. At the very least, credit must be given to Laws for his absolute audacity when she learned of his cheating, Laws admitted to the crime and claimed it was all a joke and that he had no intention of accepting the award. Whether that was true or not, we'll never know, but Laws did experience a redemption story the following year when he competed in the Boston Marathon. He won, this time with the number eight she represented puerto rico at the 1984 summer Olympics in los angeles, but to be fair, manolin had an unfair advantage a twin sister now we all know what you are thinking, and you are exactly right Madeline and Margaret made the old swap, hoping that no one would be able to tell the difference. and so it happened Madeline pulled her hamstring during the long jump competition and less than a week later she was scheduled to participate in the 4x400 relay to qualify for the finals normally this would have meant that the team would have to forfeit, but what if Margaret participated in her place? After all, she was also a track athlete and Madeleine gave her all her credentials and for a few days Margaret lived and trained in the Olympic village while successfully pretending to be her sister. Then when the big day came, the Puerto Rican team qualified for the finalshe was able to tell Madeleine Margaret apart by a beauty mark on one cheek

Resilient Cockroaches
In the Egyptian Book of the Dead, there’s a banishment spell that declares, “Be far from me, O vile cockroach.” More than 3,000 years later, we’re still trying to oust these insects. But from poison traps to hastily brandished slippers, cockroaches seem to weather just about everything we throw at them. So what makes cockroaches so hard to kill? There are nearly 5,000 cockroach species. 99% of them live in a range of habitats where they play important ecological roles by recycling dead or decaying organic matter and nourishing other animals. But a couple dozen species adapted to live in close association with humans. German and American cockroaches are among the most common. And they owe their resilience to a combination of physical and chemical adaptations. When it comes to old-fashioned removal methods, they're troublingly tenacious. An American cockroach’s sensory hairs or structures pick up subtle air currents and rapidly send signals to its central nervous system. The roach can then turn and sprint away within a few milliseconds. And it’s among the fastest invertebrates ever recorded, reaching speeds of up to 50 body lengths per second. This would be the human equivalent of running more than 300 kilometers per hour. And finding a hiding place is no problem. With its flattened, flexible body, an American cockroach can squeeze into spaces less than a quarter of its height. Even if we do land a hit, it can withstand compressive forces of up to 900 times its own weight by distributing the impact along its body. And the cockroach’s toughness doesn’t end there. Cockroaches can eat a variety of organic matter, including hair, dead skin, adhesives, and paper. This is made possible by an expansive set of digestive enzymes. Cockroaches are able to thrive even in nutrient-poor environments. Roaches often eat decaying foods that are low in nitrogen— an essential component of DNA and proteins. But they survive by storing nitrogen-containing wastes in their bodies and having a resident group of bacteria recycle the nitrogen into useful molecules for them. Meanwhile, German cockroaches will eat their own poop, vomit, and dead or dying colony members without hesitation. An American cockroach will frolic in sewers, consuming excrement and toting microbes like Staphylococcus aureus and E.coli. But they’ll rarely suffer any consequences. This is because they’re equipped with genes that provide immunity against numerous pathogens. These genes are often duplicated many times over. So when infected, the cockroach’s immune system efficiently unleashes many antimicrobial molecules. Cockroaches also have a slew of defenses against pesticides. When a non-resistant roach walks on a surface that’s been sprayed with a pyrethroid insecticide, for example, the results will likely be fatal. Once absorbed, the chemical binds to sodium channel proteins, which help propagate nerve impulses. The pyrethroid keeps the sodium channels open, so the nerves fire repeatedly. And soon, the cockroach dies. But if a resistant roach is exposed to pyrethroids, it’ll be just fine. Genetic mutations have given them sodium channels that the pyrethroids can’t bind to. The cockroach also produces more detoxification enzymes, which render the pesticide harmless, and the cockroach simply excretes it as a waste. Because German cockroaches reproduce especially quickly, populations may evolve resistance to a new pesticide within months. So far, they're already resistant to 43 different chemicals. But contrary to popular belief, cockroaches would probably not survive a nuclear apocalypse. Compared with other insects, cockroaches are only mildly tolerant to radiation. They would die near the sites of nuclear explosions and would still be severely compromised miles away. Moreover, disasters that threaten humanity also jeopardize the habitats and buffets we provide roaches. Perhaps the only way to beat them is through our mutual destruction. Or maybe cockroaches would find even more surprising ways to thrive long after we’re gone.
