Input: Consider Input: The ancient world was full of strange animals that have gone extinct, such as a group of marine species with claw-like structures emerging from their heads. A new study suggests that these creatures were related to spiders and scorpions. Researchers discovered the fossilized remains of a species in southwest China that provides new insights into the evolution of animals in the modern era, scientists said. They report their findings in the journal Nature. Scientists believe that the creature -- 1 inch long, and with two pairs of eyes -- lived 520 million years ago and that it crawled or swam in the ocean. They were able to reconstruct the creature's nervous system to gain insights about its evolutionary relationships to animals familiar to us. "For the first time, we are able to use fossilised neural anatomy to sort out how fossil animals are related to animals today," study co-author Xiaoya Ma of the Department of Earth Sciences at the Natural History Museum in London wrote in an e-mail. This creature belongs to the Alalcomenaeus genus, and its place in the animal kingdom lies in "a group of weird extinct animals" called the "megacheiran" or "great appendage" arthropods, Ma said. The species of the Alalcomenaeus group had elongated, segmented bodies with about 12 pairs of appendages they used for swimming or crawling. They also had a pair of long, scissor-like head claws, most likely for grabbing or sensing. Scientists say the reconstruction of the new creature's nervous system is the most complete for an arthropod living at that time, in the Cambrian geological period. Discovery makes a splash: The rarest whale . The brain and central nervous system of the creature are organized in a way that is similar to those of the chelicerata, the group that includes horseshoe crabs and scorpions. This suggests a close evolutionary relationship between the ancient Alalcomenaeus and the living chelicerata. A distinct group of arthropods called the mandibulates includes lobsters, insects, centipedes and millipedes. Last year at the same site in China -- called the Chengjiang formation near Kunming -- Ma and colleagues discovered a 520 million-year-old crustacean-type nervous system in an animal called Fuxianhuia. Taken together, these discoveries suggest that by 520 million years ago, the two major groups of arthropods had diverged. Their common ancestor must have been older, researchers said. "This means the ancestors of spiders and their kin lived side by side with the ancestors of crustaceans," co-author Nick Strausfeld, neuroscience professor at the University of Arizona, said in a statement. Strausfeld's team used sophisticated imaging techniques to look at the inch-long Alalcomenaeus fossil. One kind of scan revealed that iron had built up in the nervous system as the creature fossilized. They also used a technique called computed tomography that reconstructs 3-D features. By combining these images and discarding any data that weren't in both, they were able to create a sort of negative X-ray photograph, "and out popped this beautiful nervous system in startling detail,"  Strausfeld said. It confirmed what scientists had believed from the creature's outward appearance: The extinct genus Alalcomenaeus was related to chelicerates (spiders, scorpions and others). They also saw that the brain in the fossil was like the brains found in modern scorpions and spiders. If researchers find a fossil with features shared by this creature and the crustacean-like fossil Ma and colleagues found last year, that could be a common ancestor of both. There's plenty more weirdness from ancient history to uncover. 18-foot oarfish discovered .

Input: Consider Input: (CNN) -- South Korea's Red Cross has offered $8.4 million in flood aid to North Korea, the Yonhap news agency said Tuesday. The aid includes medical kits, food and emergency supplies, South Korea Unification Ministry spokesman Chun Hae-sung told reporters. The Red Cross is Seoul's main channel for humanitarian aid to North Korea. The communist nation has not replied to the offer, Chun was quoted as saying. The International Federation of Red Cross and Red Crescent Societies blamed a flash flood for displacing more than 23,000 people in a North Korean province bordering China. "The whole city of Sinuiju with its 350,000 residents is without piped drinking water at the moment because the main pumping station was inundated," said Henk Schipper, Red Cross water and sanitation delegate in North Korea. In August, nearly 260,000 people in northeastern China and North Korea fled their homes as heavy rains caused the Yalu River to overflow its banks, state news outlets in those countries reported Sunday. Tensions between North Korea and its southern neighbor have escalated since a May report from Seoul blamed North Korea for the sinking of a South Korean warship in March. The report, whose findings have been endorsed by the United States, alleged that a North Korean sub sank the ship, the Cheonan, with a torpedo, killing 46 sailors. North Korea denies it was responsible for the sinking.

Input: Consider Input: (CNN) -- U.S soccer star Robbie Rogers has "come out" as gay on the day he retired from the game Friday. The former Columbus Crew winger represented America on 18 occasions, including at the 2008 Beijing Olympics. But Rogers, who was released from his deal by second-tier club Leeds United last summer before taking up a spot with third-tier Stevenage, revealed on his blog that he is homosexual and keen to seek a life away from football. "Secrets can cause so much internal damage," Rogers wrote on his blog. "People love to preach about honesty, how honesty is so plain and simple. Try explaining to your loved ones after 25 years you are gay. "Try convincing yourself that your creator has the most wonderful purpose for you even though you were taught differently. "I always thought I could hide this secret. Football was my escape, my purpose, my identity. Football hid my secret, gave me more joy than I could have ever imagined. Soccer's last taboo: Why gay players stay in the closet . "I will always be thankful for my career. I will remember Beijing, The MLS Cup, and most of all my teammates. I will never forget the friends I have made a long the way and the friends that supported me once they knew my secret. "Now is my time to step away. It's time to discover myself away from football. It's 1 A.M. in London as I write this and I could not be happier with my decision. "Life is so full of amazing things. I realized I could only truly enjoy my life once I was honest. "Honesty is a b**** but makes life so simple and clear. My secret is gone, I am a free man, I can move on and live my life as my creator intended." Rogers' announcement has seen former teammates flock to show their support, with U.S. international defender Oguchi Onyewu, tweeting: "Extremely proud of the courage from @robbierogers. Truth is not always easy to display, but truly strong people always find a way #RESPECT" U.S. midfielder Stuart Holden added on Twitter: "Much love and respect to my boy @robbierogers ! Proud to be your friend bro." Rogers' retirement means there are still no openly gay players participating in professional football in Europe with the exception of Swedish-based Anton Hysen. 'Brave' cricketer Davies reveals he is gay . It was hoped that Hysen's coming out, which attracted headlines the world over in March 2011, would pave the way for other gay footballers to take similar steps. But not since the tragic loss of Justin Fashanu has a top-flight league witnessed an openly gay professional football player. Fashanu, who committed suicide in 1998, became the first £1 million black player in the history of English football when he signed for Nottingham Forest in 1981. While at Forest, constant rumors and speculation surrounded his private life with concocted allegations of affairs with Conservative MPs. Thomas relief after admitting he is gay . With the rumors continuing throughout his career, he finally came out in 1990 and continued to play for a whole host of lower league clubs. "You have to understand," he said in an interview before his death, "that footballers are very narrow minded people. It's the nature of the business. When you put yourself in the firing line, you are open to attack. I know I'm there to be shot down in flames." Following his passing, one particular group of fans would recite the chant: "He's gay, he's dead, he's hanging in a shed, Fashanu, Fashanu." Expert: Use gay slurs controversy to tackle homophobia in sports . While there has been huge progress since those dark days, the presence of homophobia in football has not been extinguished. Only this week, police launched an investigation into allegations that a Blackburn Rovers footballer made homophobic gestures towards Brighton fans during an English second division match. View: Hi-res gallery of openly gay athletes . Brighton, which is situated on the south coast, has a large gay population and its fans are often targeted with homophobic chants. "I think there's a big culture shift needed within football from the grassroots to the top of the game," Louise Englefield of FootballvHomophobia told CNN . "The top of the game is a symptom of a much wider issue about lack of awareness and ignorance around the ability of gay men to participate and excel at football . "When you've got a lack of gay players at the top level, then it's easy for that environment to be quite negative. "I imagine there are players who are reticent to come out." Opinion: Why the fuss about gay marriage? While other sports have embraced their gay stars, such as John Amaechi in basketball, Martina Navratilova in tennis and Gareth Thomas in rugby, football has yet to move with the times. Off the field, the UK Parliament backed a bill to legalize gay marriage earlier this month as society continues to move forward. And while football has yet to move with the times, progress is being made. Premier League and Football League clubs in the UK have created several initiatives to combat homophobia, working alongside charities such as HvF. "Within football, people don't understand the seriousness of homophobia," added Englefield. "The things fans shout at players, they believe it's not hurting them and they don't care if they're gay or not. "Homophobia is used to put players down and it's a way of deriding players. That's cultural all the way through football and happens in other sports. "When a player gives a pass away or falls over, fans use homophobia abuse to put them down and it's that which we want to stop. "One of our key things is changing chanting in the stadium. Stop and think before you chant." Liverpool youngster Suso fined for calling teammate 'gay' A particular success story in England has been the creation of the GFSN Gay National League, where "gay friendly" teams compete on a regular basis. Rogers' story has been met with admiration from fellow gay football players, but his retirement from the game means that the community is still waiting for a player to come out and continue playing. "The great pity with Robbie is that he felt it was an 'either or choice,' " Scott Lawley, who plays for Nottingham Ball Bois in the GFSN Gay National League told CNN. "Reading his blog, it felt as if he thought he had no choice but to quit football if he wanted come out. "He could have easily retired without coming out but he's been very brave and hopefully set us in the right direction. "He hasn't forced us to the point where a gay man runs out in front of 30,000 people to play football . "And the fact that no professional player has come out in recent years means there are still issues to deal with. "But we will come to that day when we do have openly gay players in the top divisions and we're moving in the right direction."
