How are you, sunshine? Congratulations on "Your Word Wednesday." Some of you helped us write today's issue with a word you sent. So listen carefully, you may have sent the winning word. And happy October Eve to you. I am Koy Waer. This is CNN 10, your news for Wednesday , September 30th. 10 minutes, big world. Let's get smarter and rise higher. Let's start with a blood test that could eventually change the way doctors approach cancer detection. An FDA advisory panel has endorsed the Galleri blood test, designed to detect signals from more than 50 types of cancer in a single blood draw. But this test has its limitations. Our chief medical correspondent, Dr. Sanjay Gupta, wanted to understand what this test can and cannot do . His research became personal because he experienced it for himself. You automatically see this bright spot right here. She shines like a light bulb. This tumor sat there and caused no problems. And the funny thing is, when I first met my thoracic surgeon , he came in, shook my hand, and said, "You might be the luckiest loser ." Unlucky, because I got a positive result , but lucky, because he never sees such small tumors. Katrina Furlik and I have been friends for years. She credits her luck to a blood test that aims to detect cancer in its early stages. They're called liquid biopsies—a test for the early detection of many types of cancer that can identify over 50 diseases by looking for fragments of DNA in your blood. I didn't have to go through any cancer crisis. I was able to intercept this crisis. Many doctors promote early screening, and the numbers back this up. From 1975 to 2020, nearly 5 million cancer deaths were averted through routine prevention and standard screenings. The problem is that there is no recommended screening test for most diagnosed cancers. As a result, many of these cases are detected later and are more difficult to treat. You are my friend and fellow neurosurgeon. We are the same age. Do you think I should take this test? Do you like the idea of ​​detecting cancer at an early stage? I like the idea of ​​early cancer detection, but at the same time, I'm not sure if I really need to have such a test. And here's why . These tests have what is called a high positive predictive value. If the result is positive , then I most likely have some form of cancer . But at the same time, if the result is negative , I don't have complete confidence that I don't have cancer. After over 5 years of work and nearly 10,000 lymph node biopsies, fewer than twelve cases of cancer were found. So, it doesn't detect as many cancers as we would like. It does not detect cancer 100% . Dr. Versali Shukla runs a cancer screening program for lifeguards in Arizona. They are often younger than the 50- and-over group for which these tests are designed , but studies also show that firefighters have higher rates of cancer due to their work We went to work in one week and took tests from 500 firefighters. We tested all their blood and not a single result was positive. And no one wants to come for the examination because everyone felt this false sense of security. I think you're painting a picture where a person takes the Grail test, gets a negative result, and thinks, " Hey, I'm fine." " I don't need a colonoscopy or additional screening." It took us a lot of effort over the next 18 months to 2 years to get all these people to come in for a colonoscopy or a full-body MRI. As a result, we diagnosed another 14-15 cases of cancer. It's hard to understand this psychologically when I'm going through this test myself. A negative result doesn't mean I'm safe. This also doesn't mean I should skip cancer screenings. Even test manufacturers talk about it. And, importantly, we do n't yet have studies that prove whether these tests save lives. This requires many more people and much more time. But there is also the story of Katrina. In my case, the advantage was that I needed minimal treatment . I discovered this at the earliest stage. The last few weeks waiting for the results have been quite nerve-wracking. So, that's the thing. There are over 600 FDA-approved cancer treatments. We can't take advantage of them if we don't know we're sick and we don't find these tumors early enough. In my case, the result was negative. No signs of cancer were found. Now about the high-profile hack that surprised the FBI. The Federal Bureau of Investigation says it is investigating an alleged intrusion into its networks after the notorious cybercrime group Shiny Hunters stole the personal information of thousands of FBI employees. The incident forced the FBI to shut down the job listings page on its main website while it investigates the extent of the hack. The Shiny Hunters group says it was, quote, offended by the recent public warning issued by the bureau. It analyzed the group's alleged tactics of extorting money from large companies in technology, healthcare, finance, and other industries by stealing millions of their customer records. Shiny Hunters claim that the hack had no financial purpose and are demanding that the FBI change or remove this warning. Quick test, friend. What is the fewest number of moves required to checkmate in a standard game of chess? Two, four, six or eight? If you said "two", then it's checkmate. The fastest possible ending is called "silly checkmate". Only Black can do this on his second move if White makes two blunders, or what some of us players would call rookie mistakes. And now, an incredible achievement from the world of chess that is worth pondering. Last year, we introduced you to British chess prodigy Bodhana Sivanandan, who became the youngest player ever to defeat a grandmaster. Well, she just made history again. Last weekend, aged just 11, Bodhana fulfilled the requirements to become the youngest female grandmaster in history, cementing the achievement by representing England at the 46th Chess Olympiad. Bodhana first took up chess at just 5 years old, after a family friend gave them a chess set during the COVID-19 pandemic. Somehow, her meteoric rise coincided with her studies at school. She says chess actually combines some of the subjects she loves most. They are connected to many school subjects: math— helps with counting, music —helps with pattern recognition (I play the violin and a little bit of the piano), and art— creativity, so there is a connection. At 11 years old, she's still writing a story and doing her homework— that's what I call being a few moves ahead. Next, they say that imitation is the sincerest form of flattery, but sometimes you can get sued for it. Crocs is suing discount retailer 5 Below. Crocs and its subsidiary Jibbitz accused the retailer of selling shoes and decorative accessories that copied Crocs' protected designs. Crocs says it warned 5 Below back in March, but claims the products continued to be sold. Crocs is seeking a jury trial, unspecified damages and an injunction against the sale of these products. The parties involved have not yet responded to media requests for comment on this incident. Last quarter, Crocs sales topped $1 billion for the first time . Their sales increased by 12%. Today's story is a 10 out of 10 for all those whose dance moves look a little " awkward". It turns out that cockatoos know how to fly. You've probably seen videos of these birds dancing, jumping, and shaking their tail feathers. Researchers from Charles Sturt University in Australia say these incredible cockatoo movements indicate high intelligence. Our Shannon Hodge will tell you more. They definitely don't have two left legs. Social media is full of videos of cockatoos having a blast . New research shows that these intelligent birds have dozens of dance moves, including several newly discovered ones. Researchers studied 45 videos from social media where cockatoos are lit to music. The results, published in the open-access journal PLoS One, suggest that cockatoos have at least 30 different movements. 17 of them have not been previously scientifically described. This includes head shaking, side steps, and body rotations. Some even invent their own unique ways of dancing, often combining several movements. Dancing to music has only been recorded in humans and captive parrots. However, some wild birds are known to exhibit repetitive movements during courtship. Cockatoos, which belong to the parrot family, are known for dancing to music in captivity. But researchers say their motivation remains unclear. So the next time you're on the dance floor thinking "I have no idea what I'm doing," take inspiration from the birds. Nod your head, ruffle your feathers, and don't hesitate, because confidence can turn awkwardness into coolness. Congratulations to the winners of our "Your Word Wednesday" column: Ms. Tull, Ms. Wolf, and Mr. Subbarayadu from Strongsville High School in Ohio for the word "kerfuffle"—a noun meaning a disorder or commotion, usually caused by an argument or conflict. I take my hat off to you, friends. Thanks for sending this, making us a little smarter today. And today we extend our congratulations to Mr. B from Owaihi High School in Meridian, Ohio. Congratulations on receiving the title of "Teacher of the Month." Mr. B says that this is the merit of his students, so his reward is also their reward. And the class even sent us a joke. What do overly curious peppers do? They are meddling in their own business (jalapeño business). Climb higher. These are our 10 minutes . Learn, work, shine. See you tomorrow, sunshine. I am Koy Waer. We are CNN 10.
