How scientists proved horses really can smell fear

Rise up, sunshine. Happy Friday, Friday. I'm Coy Wire. Welcome to CNN 10. I am packing my bags to cover the college football playoff national championship. between the Miami Hurricanes and the Indiana Hoosiers. So if you are down in the 305 and you see your guy, come say hi. Now, let's get our minds right and finish this week strong. Four astronauts are safely back on Earth after...

Health concerns forced a rare early departure from the International Space Station, or ISS. The Crew-11 astronauts successfully splashed down in the Pacific Ocean early Thursday, about 10 hours after... undocking from the ISS aboard a SpaceX Crew Dragon capsule. It kept a week long effort to get them home after NASA announced they were canceling an upcoming spacewalk.

due to an unnamed crew member's medical issue. On behalf of SpaceX and NASA, welcome home, Crew 11. SpaceX Dragon, it's so good to be home. With deep gratitude to the teams who got us there and back. The crew was all smiles as they exited the capsule, giving a thumbs up as they took their first steps after more than five months in space. They were taken to a nearby hospital for routine medical checks, which is common protocol due to the...

strenuous toll that re-entry into the Earth's atmosphere takes on the body. Officials did not reveal what the medical concerns are for the unnamed astronaut, though they did say it was not due to an injury. They also said it's easier to examine them a fully equipped medical facility back here on Earth. Obviously, we took this action because it was a serious medical condition, right?

In that respect, it was a serious situation. The astronaut in question is fine right now, good spirits, and going through the proper medical checkouts. The early departure has left the ISS with a skeleton crew of just three astronauts manning operations until crew 12 astronauts arrive next month to take over.

Alright, some may have thought this was an old wives tale, but now there is scientific proof that horses can sense fear and that they can actually smell it. And one of the most intriguing aspects of this discovery is how researchers figured this out. If you're like me, you might be wondering, what does fear even smell like? Well, scientists at the French Institute for Horse and Riding put cotton pads in the armpits of study participants. Then they showed the participants either scary...

or joyful videos to collect what they call odor compounds. Then researchers put those pads on the muzzles of 43 horses to see how they reacted. The horses who smelled fear were more likely to startle easily. less likely to approach people, less likely to be inquisitive and investigate unfamiliar objects. Here's the advice from the scientists involved.

Though you can't control the smells you give off when afraid, when you're on or near a horse, you should, quote, focus on relaxing so you can ride calmly and without fear. Pop quiz, hotshot. What is the valid target area in foil fencing? The entire body, the torso only, the head and arms, or from waist down. If you said torso on guard, the minimum score needed to win a standard individual at fencing about is 15 touches. Unless time runs out.

I'll try not to foil this next story with too many puns and get right to the point. In Qatar, a former Team USA fencing phenom is epaying it forward and writing her latest chapter. Ittihaj Mohamed made history at the 2016 Rio Games, becoming not only the first American woman to compete in a hijab, but also the first Muslim American woman to win an Olympic medal.

Now the trailblazing athlete is helping a new generation of female fencers hone their skills. Our Matias Grez picked up a sword for an up-close encounter. Welcome to the Rec Center in Education City where today I'll be speaking to US Olympic fencer Ibtihaj Mohamed who became a household name overnight at Rio 2016 when she became the first US athlete to wear a hijab at an Olympic games. Now in Qatar she is aiming to inspire and empower young girls to get into sport but in particular into fencing.

I heard maybe one of you is going to fence against me. So whoever it is, just take it easy, OK? Matthias, you ready? Crash course, guys, come on. I'm about to play a game of Fencing Simon Says. but this version with a sword in my hand. This is your blade. Okay, everybody have a blade. Are you ready? Simon says? As ready as I'll ever be. Okay. Simon says... Advance. Retreat. We gotta wait for Simon. I'm not ready. Simon says retreat. Simon says retreat. Simon says advance. Lunge.

While it might be too late for me to make the Olympics, these girls seem to have the talent and work ethic to go all the way. And learning from an Olympic medalist like Ibtihaj will certainly help. And how have you found working with Ibtihaj? She's been very nice, she's a very nice and sweet person. Her tips are very helpful and I can feel they're relatable because she's been where I've been and much more so I'm hoping to.

reach where she visits. One of the girls I spoke to actually said that her motivation to get into fencing was because she saw you at Rio 2016. I mean when you hear stories like that from girls that you're teaching, how does that make you feel? You know, it gives me chills because sometimes I forget that I actually went to the Olympics and won a medal. You dedicate all of your time, all of your energy into a dream, and you don't always know if that dream will come to fruition.

to have that moment come true for me and go to the Olympics and win a medal, but then icing on the cake, you know, to inspire the next generation. Recover. Retreat. Anything I've done in sport, these girls are able to achieve a lot more because I do believe that things become easier when you've seen it done and you know that it's possible for you.

Well, when he found few resources focused on their state's history, he began creating his own. Writing the lyrics and choosing the style, letting AI handle the music arrangement.

I try to make my prompts really precise. I'll add in files as well of documents so I know it's pulling from accurate information. I always proofread everything. Mai says the music keeps students engaged and helps reinforce key concepts, often replaying in their heads during class. and tests. This has inspired students to create their own songs and poems.
