We have drawn heart symbols for centuries as a sign of our affection and love but where did the heart shape come from since it looks nothing like our hearts? Read more about the differences between the anatomical heart and the heart symbol here.

NASA has successfully tested a positioning system on the Moon that will allow for the safer navigation of rovers and humans on the lunar surface. The test, conducted in February, was part of Intuitive Machine's Odysseus mission. Called Lunar Node 1 (LN-1), the beacon was turned on for 30 total minutes and showcased how it can be used to find where one is on the surface.LN-1 verifies the position of individuals with other sources in the network such as spacecraft in orbits, ground stations, or even other individuals. The system conducted two 15-minute transmissions and the signal was successfully locked to NASA’s Deep Space Network. The team was able to receive telemetry and navigation measurements from it.        IFLScience is not responsible for content shared from external sites.“We’ve lit a temporary beacon on the lunar shore,” Evan Anzalone, LN-1 principal investigator at NASA’s Marshall Space Flight Center, said in a statement. “Now, we seek to deliver a sustainable local network – a series of lighthouses that point the way for spacecraft and ground crews to safely, confidently spread out and explore.”Odysseus had some trouble landing, as it reached the surface at a funny angle. This led to cutting down the originally planned time for testing LN-1 from 10 hours a day across the whole mission to just 30 minutes in total. Still, LN-1 actually provided critical backup for the mission onboard navigation system, showing that this tech is up to the task.The team envisions a network of lunar nodes that can monitor the “traffic” around and on the Moon. Together with systems like the Vikram retroreflector tested last year, and other initiatives from NASA and other agencies, the system will become part of a larger LunaNet. And this tech might, in the future, be key to the exploration of Mars. The Moon is about one light-second away; if the position comes exclusively from Earth, signals to and from take just a couple of seconds to reach astronauts that need navigation. On Mars, we’d be looking at 20 minutes of delays, on average.“That’s a very long time to wait for a spacecraft pilot making a precision orbital adjustment, or humans traversing uncharted Martian landscapes,” Anzalone said. “LN-1 can make lighthouse beacons of every explorer, vehicle, temporary or long-term camp, and site of interest we send to the Moon and to Mars.”Let's look forward to more tests of these systems, hopefully with some humans involved in the future Artemis missions.

Click to Skip Ahead Benefits Issues Oxtail Meat Alternatives to Bones One of the most common associations we have when we think of dogs is a dog with a bone. Years ago, it was common to just hand over any old bone to your dog, but today, we know this isn’t always a good idea. But what about oxtail bones? Oxtail bones may be safe for some dogs, but this depends on your dog’s size and eating habits. Cooked oxtail bones should also never be given to your dog as there is a substantial risk of the bone splintering and becoming a choking or obstruction hazard. We’ll give you more information about the benefits of oxtail bones for your dog as well as the potential dangers for you to be aware of. How Are Oxtail Bones Beneficial? Oxtail bones are the tails of cattle and can be purchased as a cross-section or whole. They are typically found with a thick and large bone in the middle surrounded by meat and fat. Some of the benefits of oxtail bones are: Keeps them occupied: Chewing away on an oxtail bone can also help occupy a dog. This can be a great way to keep them mentally occupied, particularly if they engage in behaviors from anxiety, such as excessive licking or pacing. Nutrients: Oxtail bones can provide some beneficial nutrients, and it doesn’t hurt that dogs love them! Theycontain fat and protein and provide your dog with sodium, potassium, calcium, magnesium, phosphorus, and other minerals. However, these benefits only translate when oxtail is used as a dietary supplement (for example, if it is ground and mixed in a dog’s diet). What Are the Issues With Giving Dogs Oxtail Bones? For the most part, giving a dog an oxtail bone can be beneficial in some ways, but there are some pretty significant issues as well. Small Breeds Small dogs shouldn’t be given oxtail bones, and in some cases, they shouldn’t be given any bones at all. Small or toy dogs, particularly those with small jaws and softer teeth, shouldn’t be given oxtail bones. They are better off with something like chicken necks. Additionally, brachycephalic breeds have small jaw structures, which can lead to dental issues like overlapping and overcrowded teeth. Image Credit: Grayson Schmidt, Shutterstock Cooked Bones It’s never okay to give your dog a cooked bone as the bone dries out and becomes more brittle through the cooking process. This means it’s quite easy for the bone to splinter, which can damage the dog’s teeth, gums, throat, and gastrointestinal tract. Poultry bones and fish bones are amongst the worst culprits. Additionally, many of the seasonings we use on meat can be toxic for dogs. You’ll want to avoid giving your dog any bones cooked in seasonings or any food off your plate. Raw Bones While raw bones are the best option, there is still a risk of bacteria causing Salmonella infection, which can be spread to us. This is a serious disease that isn’t terribly common in dogs, but there’s the potential when you’re not cooking the bone. If your dog exhibits any of the following signs after chewing on a raw bone, you should bring your dog to the vet immediately: Diarrhea Fever Vomiting Weight loss Dehydration Rapid heart rate Generally speaking though, the risk of such infections is very rare for healthy dogs that are offered human-grade oxtail bones. Image Credit: Zontica, Shutterstock Tooth and Gum Damage If you don’t choose the right bone size for your dog, there’s a risk of tooth breakage and damage to the dog’s gums. Not only is the wrong size of bone a problem, but damage can occur with even an appropriately sized bone. The gums might get punctured, or they could break some teeth while gnawing. Jaw Damage Some dogs can potentially damage their jaws by trying to fit their mouth around the bone. Round bones, like oxtail, can also potentially become stuck around your dog’s lower jaw behind the lower canine teeth. Image Credit: Yavdat, Shutterstock Choking Risk Choking is one of the most significant reasons why some veterinarians are against dogs chewing on bones. This point also depends again on the bone’s size and how your dog tends to eat. Remember to always monitor your dog anytime you give them anything to chew on. If your dog is a careful chewer of food and chew toys, they might be okay with a bone. But dogs that gulp their food down should probably avoid bones, as this is when choking can occur. When chewing on an oxtail bone, some dogs might swallow it whole, where it could get stuck in the throat. Or the splinters of the bone could make their way into the intestinal tract and stomach, where they could cause damage. Obstruction When a dog chews off a large piece of bone and swallows it, they won’t be able to digest it. This undigested piece of bone might result in the obstruction of the digestive tract, often referred to as a gastrointestinal obstruction. Such dogs need medical care from a veterinarian (which may involve surgery). Image Credit: Goldfish Studio, Shutterstock Can You Feed Your Dog Oxtail Meat? As long as the bone is removed before giving it to your dog and it hasn’t been cooked with any seasonings or oils, oxtail meat on its own is a tasty treat for most dogs. Don’t forget that things like onions and garlic are quite toxic for dogs. They’ll enjoy the cooked or raw meat without any special preparation. You can also consider making bone broth for your dog following dog-specific recipes. Image Credit: Food Impressions, Shutterstock Alternatives to Bones Judging from the opinions of many the FDA and the long list of risks associated with bones, giving your dog an oxtail bone, or any bone for that matter, might not be worth it. Many dogs do successfully chew on bones without any issues, but in some cases you might need alternatives. Veterinary Oral Health Council-approved rawhide is an alternative chew that you can try for your dog. Bear in mind that the same rules apply to any chewing treats as they do to bones. You want to ensure they are the right size for your dog, and you should monitor your dog at all times when they’re chewing on it. However, hides might not be appropriate for all dogs, and further input from your veterinarian is advised prior to considering them for your pet. You can also try some dental chews as a means to keep your dog’s teeth healthy and clean. And regardless of what your dog is chewing, always supervise while they are gnawing away. If you notice large pieces of bone or chew that have come loose, take any pieces away from your dog before they swallow them. Conclusion Whether or not you give your dog an oxtail bone, consider speaking to your vet before you try it. They might have an opinion on this and can provide you with feedback as to whether they are a safe treat for your dog. If you decide to try out an oxtail bone on your dog, ensure you purchase it from stores that have them prepared and cut very specifically for dogs. Remember to always keep an eye on your dog while they are chewing anything. The chew should be taken from them if it becomes too small, if you notice any blood on the bone and around their mouth, if your dog chews/eats very quickly, or if your dog seems to be in discomfort or pain while chewing.

UFC fighter Sean Strickland spoke out against the NFL and negative reactions to a speech by Kansas City Chiefs kicker Harrison Butker at a Catholic college.Butker delivered an anti-politically correct commencement address to hundreds of graduates at Benedictine College, calling out President Biden, diversity programs, and the role of men in society.Strickland, who has never been shy about giving his unfiltered opinion, chimed in once again calling the NFL "spineless cowards" after a league representative distanced the NFL from Butker's comments."Harrison Butker gave a speech in his personal capacity," senior vice president and chief diversity and inclusion officer Jonathan Beane said. "His views are not those of the NFL as an organization. The NFL is steadfast in our commitment to inclusion, which only makes our league stronger," the DEI chief added, according to USA Today.'You can be against gay marriage. It's ok. You're not a bigot.'Strickland wrote days later on X: "When did the NFL become such spineless cowards? MAN + WOMAN = MARRIAGE[.] Nothing else," he continued."Text, history and tradition ... It's that simple 'It doesn't matter, who cares who can get married' Saying that makes you a weak man. They want you to say that ... Have beliefs," the middleweight wrote. — (@) In another post 17 minutes later, Strickland clarified that he didn't have any hatred toward gay people."There is not one ounce of me who hates gay people. If you're gay be gay. Be happy. I wish you the best[.] But that doesn't mean I have to bend my knee on every social issue designed to destroy America and masculinity," he continued. "You can be against gay marriage. It's ok. You're not a bigot nfl."An OnlyFans model responded to Strickland in support, saying, "[The] institution of marriage was predicated on having kids and two dudes can’t do that.""This is a reasonable take, what we are against is teaching it to kindergarteners and life altering procedures/medication to under 18 year olds," the woman added.Strickland replied with, "100 percent." — (@) Strickland's most recent statements surrounded his displeasure with foreign flags consistently being flown in the United States."I'm so sick of seeing foreign flags in America.. I don't get it," Strickland wrote on X. "You left your corrupt country to come to the USA and yet you still rep what you fled? The worst is Hispanics born in America flying a Mexican flag.. Where is your loyalty.. Just go back.. Enjoy your foreign flag," he added.This included the Israeli and Ukrainian flags being celebrated by U.S. politicians, as well.As for Butker, he has received support from teammate and star quarterback Patrick Mahomes, who said that Butker is a "good person" and is someone who "cares about the people around him" and "cares about his family."Chiefs head coach Andy Reid also said that he didn't think Butker was "speaking ill to women." "He has his opinions, and we all respect that. I let you guys in this room, and you have a lot of opinions that I don't like, so," Reid added.Like Blaze News?

Republicans have announced a new bill that declares in vitro fertilization a right, and Sen. Ted Cruz (R-Texas) is leading the charge alongside Sen. Katie Britt (R-Ala.). “We came together, and said let’s draft a simple, straightforward, federal bill that creates a federal right that you as a parent have a right to have access to IVF,” Cruz said. “If you want to have a child and you need medical assistance to do so, that should be your right,” he concluded. "A right to IVF," Allie Beth Stuckey mimics in clear disagreement. Associate professor at the Southern Baptist Theological Seminary Andrew T. Walker is also extremely disappointed. “I was really discouraged with this legislation coming out from two senators,” Walker tells Stuckey. “This is obviously coming in the aftermath of the Alabama Supreme Court decision from earlier in the year, but I think tragically, they’re going further out in support of a practice that, tragically, most Americans are just woefully misinformed about when it comes to what IVF is.” “It’s an affront to human dignity, in the service of so-called support for human dignity,” he adds. Stuckey is in firm agreement. “Yes, we like to say that when technology takes us from what is natural to what is possible, Christians have the responsibility to ask, ‘But is this moral?’ And more important, ‘Is this biblical?’” Stuckey says. “Catholic teaching takes issue with removing or with separating reproduction from sex, which I think is good, and I think is fair. Because when you make that separation, all kinds of ethical issues flow from that,” she adds. Not only is the process unnatural, but it isn’t consistent with the beliefs of those who claim to be pro-life. “If life starts at conception, then how we treat embryos matters. IVF very often includes a eugenics process of selecting the best embryos and discarding the others,” Stuckey explains, adding, “If life begins at conception, then how can we say that we have a right to IVF when inherent in IVF is the mistreatment of these little human beings made in God’s image?” Want more from Allie Beth Stuckey?To enjoy more of Allie’s upbeat and in-depth coverage of culture, news, and theology from a Christian, conservative perspective, subscribe to BlazeTV — the largest multi-platform network of voices who love America, defend the Constitution, and live the American dream.

Virginia Gov. Glenn Youngkin (R) sent a letter on Wednesday to President Joe Biden demanding a formal briefing regarding an incident that took place on May 3 near Triangle, Virginia, involving two suspected illegal immigrants.Two Jordanian males posing as Amazon delivery drivers attempted to gain unauthorized access to Quantico Marine Corps Base, Blaze News previously reported. After driving a box truck up to the base's main gate and failing to produce access credentials, guards instructed the two men to wait in a holding area so a secondary inspection could be performed. '... reiterates the gravity of your failure to secure the southern border.'Captain Michael Curtis told Potomac Local News, which initially reported on the incident, that military police officers observed the driver "ignoring the direct instructions" and attempting "to move the vehicle past the holding area."The officers successfully initiated the vehicle denial barriers, blocking the box truck from proceeding farther on the military base. According to Curtis, the two suspects were turned over to Immigration and Customs Enforcement, but it was not immediately clear whether the men were both residing in the country illegally. Youngkin told Fox News Digital on Wednesday that the Biden administration has still not briefed him about the incident or admitted that the men were illegally in the U.S. — (@) In a letter to Biden, Youngkin wrote, "I am deeply concerned about what appears to be a series of recent attempts to gain unauthorized access to United States military installations, including two in the Commonwealth of Virginia. The federal government has not provided adequate information to Virginia on these matters, and the publicly available facts are disturbing.""The attempted breach at Quantico, and the federal government's silence on the immigration status of the individuals involved, reiterates the gravity of your failure to secure the southern border, and to provide state governments notice of illegal migrant relocations so I can protect the safety of all Virginians," the governor continued. "Today, I am formally requesting that you immediately provide my Public Safety and Homeland Security leadership team and me a full briefing on these events."According to Youngkin, one of the suspects is believed to have illegally crossed the southern border into California. The man was allegedly provided a Notice to Appear "but was ultimately released.""The second individual is believed to have entered the United States on a student visa which was terminated in January 2023 due to failure to maintain enrollment," Youngkin stated. "His continuing to reside in the United States without a visa would deem his residence illegal." — (@) The governor told Fox News Digital that, as of Wednesday, he had not heard back from the Biden administration."Let's just be clear, Joe Biden has brought the border crisis literally to the front gate of Quantico Marine Corps Base," Youngkin told the news outlet. "What we know — at least reported — are two Jordanian illegal immigrants were driving a box truck through a secure gate and, luckily, they were stopped."Like Blaze News?
