ICYMI: Popl beams contacts to phones
"Of the big problems many of us has is nobody wants to hand out business cards anymore but everybody wants our contact information. What to do I, think we all have a bunch of different solutions but nick. And Jason Alvarez Cohen have happy device called paypal which can pass on your information and the guys are here and they're going to tell you all about it. He Nick and Jason Jeff send thank you for having us on. Sure. Tell us about poppel. So. Papa. Is Your new digital business card. It's a small thing you put on the back of your phone. And then all you have to do is just tap it to someone else's phone like this. It sends a push notification to that phone and win that notification is clicked at sends you right to send them right to my profile, which has my website, my instagram, my phone number, all of my contact information right on their screen. Okay. So what you just showed me was a little round ball basically and in you you I, guess he velcro or something or or a magnet or as probably a magnet right to. And it sticks to the back and then it then up your APP in that swirl, your contact information is in Europe. They have a pop up, it opens up in that but if they don't have the APP, it opens up in the browser and the key to the product is that the other person does not need poppel or an APP for you to share your mation. Believe that the Pablo's are very inexpensive how much they sell for Fourteen ninety nine for basic potholes and nineteen ninety nine for premium populous. What is a premium poppel? A premium poppel has nicer textures this one. For example, we poppel prism. It's kind of. Holographic. The basic ones are black white pink, blue jays color. Yeah and the premium ones are. Little, fancy same functionality, just different looking field Lyndon Okay and obviously once you once you download your APP, you then spend time in putting your basic. referrals. Correct, it's very easy setup you get your pop in the mail you you you put in what you want. Then you activate it with your phone and then you're all set. So you can put on your phone upon your laptop on your car, your Papa anywhere. It'll share where you want to share. So if you put it on your laptop and I had somebody in the office. Where I met somebody at starbucks right in a post Kobe world and I wanted his or her information. They would just put their phone in front of the Little Poppel that was on my laptop Yep. It's that easy. What motivated you guys to come up with this idea? Greg Russia. Well, we're both recent college grads and we learn about the psychology at how cool is and how native it is in modern phone. So we saw this use case as two guys who never used. A really cool phone, the phone method of Sheriff Mason which we did often. So we saw the cell division just credit. All right. Well, congratulations people can get it and is it Papa Dot Com. Pablo.

What Does The Science Say
"Welcome to kids, myths and mysteries. Stores were strange and unexplained people, places and events. I'm your host Kit crumb today fringe science. Sciences defined as intellectual practical activity, encompassing the systematic study of the structure and behavior of the physical natural world through observation and experiment. Fringe Science is considered an inquiry into an established field of study and departs from mainstream theories in that field and is considered to be questionable by mainstream science. Now. Don't confuse fringe science with pseudoscience, which is defined as a belief in some person place or event that is mistakenly regarded as being based on scientific method but many categories once considered the product of pseudoscience have slipped into the category of fringe science and many fringe science categories are now consider pure science. A short list of categories considered to be a fringe science, include cryogenics reanimation, and suspended animation. Now, let's take a quick look at each of these. cryogenics is generally the practice according to Al Core cryonic center in Arizona of freezing people who need a cure for a disease or perhaps are in need of an Oregon and will be thought at some later time when there is a cure or an organ available. Now Look at the second fringe science on my list reanimation. That is usually thought to mean restoring life. Finally the third on my list suspended animation that would be closer to the cryogenics. Separately these three would be considered by science to be way out on the French but alcorn does freeze patients and that would seem to be suspended animation, and if indeed the patients brought back to life, you would have to call latte reanimation. Still Science would scoff at the concept yet in Japan Cell Nuclei and DNA were taken from a woolly mammoth that live twenty eight thousand years ago and implanted by scientists into the cells and Ogm of living. Five showed essential biological reactions needed for cell division. This could lead to the reanimation. Mammoth. From the frozen north where the woolly mammoth was the unsuspecting subject of natural cryogenics to lab in Japan where the mammoths DNA was brought from a state of suspended animation. To a reanimated state and planted into the oval ma-ma mouse I'd have to say that's cryogenic suspended animation and reanimation that have slipped from fringe science too pure science. Now, let's plunged down the list of fringe science to the much-maligned topic pre cognition. Simply precondition is considered the fore knowledge of an event. Let's take on a huge event debt even titanic in size, and that's pun intended. It's common knowledge that the titanic was the largest cruise ship of its time. It was considered unsinkable and perhaps because of that Monica unsinkable, it didn't have enough lifeboats for all the passengers when in mid April nineteen twelve on its maiden voyage, it hit an iceberg it sank taking with it over one, thousand, five, hundred passengers but fourteen years prior to the sinking author Morgan Robertson wrote a book titled Futility described the largest cruise ship in the world he named Titan in his book he described his ship as unsinkable and not carrying enough lifeboats for the passengers. When it in his book struck an iceberg in mid April over a thousand died strangely there are well over one dozen similarities between Robertson's Titan and the titanic. And remember he wrote about the Titan in eighteen ninety eight. Pre Cognition. Well, what else could it be? Moving along the list of fringe science, you'd find past life regression hypnotism Bo scoffed at by science at both used by licensed and highly educated counselors around the world although the list of practices an event that fall under the shadow of fringe science as long one I couldn't resist looking at artificial intelligence. You probably heard of IBM's corporations creation Watson. But Watson is program to teach itself in whatever endeavor it is directed. Intelligence natural kind you and I possess is not the same intelligence. Watson has watson can look at a room elementary students and evaluate. Standing Body language which students are following the teachers teachings which are confused and which are distracted. But the natural intelligence that you and I possess would not only separate the students in those three categories mentioned. We could probably figure out why those that followed the teacher could why those that didn't couldn't and what distracted the remainder.
Could Genetics Grow a Square Tomato?
"Today's episode is brought to you by smart water twenty years ago. Smart water, reimagined, what water could be from thoughtful bottle designed to supporting smart people who are changing our world through fresh thinking. Like, you smart water has added electrolytes for taste and great tasting water helps you stay hydrated, feeling refreshed and ready to take on your day. Refresh yourself with smart water. Welcome to brain stuff from how stuff works. Hey, brain stuff. I'm Lauren vocal bomb. And if you wander the protas, I'll at your local grocery store, you'll find a dazzling variety of tomatoes from Charrier grape shaped to massive beef steaks and gnarly heirlooms same with squash potatoes, cucumbers and leafy greens. This bounty of diverse colors shapes and sizes isn't the result of natural selection. But rather human selection over millennia farmers and plant breeders have spotted useful mutations and fruits and vegetables, tastier fruit. Better yields novel shapes and preserved those traits through conventional breeding techniques the process is slow. But if you cross different strains enough times eventually you may create something new enough and marketable enough to be called its own variety. That's low and steady. Conventional breeding process is about to get a big boost from advances in genetic mapping with a tomato or cucumber genome in hand plant breeders, don't have to wait months for tomato plant to bear fruit to know, whether the tomatoes will be pear shaped or round. Instead, they can look for telltale markers and a seedlings DNA the code for specific fruit shape, size and color this technique of marker assisted selection promises to cut years off the traditional plant breeding process. One Esther vendor nap is at the forefront of genetic research into exactly how a plans DNA instructs fruit to grow long and lean like a hothouse cucumber or round and squat like a beefsteak tomato in her lab at the university of Georgia post, docs and undergraduates sliced tomatoes in half in place them on a flatbed scanner to measure the precise shapes and sizes produced by different genetic combinations. In a paper published in November of two thousand eighteen in the journal nature communications Vander nab announced the discovery of two. Families of genes that appear to play key roles and making fruits and vegetables, either round or long fruits and vegetables are technically plants edible organs and those organs grow and develop through cell division. She explained to make a certain shape like a long around shape, you need to have certain patterns of cell division. Either the cells divide horizontally, or they divide vertically, which makes sense the more Oregon cells divide horizontally by splitting down the middle. The more. They're going to build up tissue horizontally, creating a fatter rounder fruit. What Vander nap and her colleagues discovered in the tomato. Genome is a specific gene called ov- eight that appears to be responsible for creating proteins that tell cells to divide in a vertical pattern when more cells split side side, the growth pattern produces at en- long gated fruit. Ov- eight is the difference between a perfectly round cherry tomato and an oblong Plum tomato. Wild tomatoes, like the native varieties found in Peru. Ecuador and Mexico are invariably small and round says Vander nap which means pear shaped and other in long gated tomatoes are mutations that came along later as far back as the nineteen thirties. Plant biologists called the long Gatien mutation ov- eight but had no clue about the actual genetic mechanism behind it. But van nap and her team identified the ovation protein as well as another family of proteins called TRM's that interact with Lovie, and it provides another tool to plant breeders who are using marker assisted selection, if the ov- eight N, T R and markers are present. You can be sure the fruit will be in long gated if one or the other is missing. It's backed round evanger, nap says this will speed up the breeding process and let growers focus on trickier traits. Like yield and pest resistance that aren't as easily linked back to one or two specific genes. So now the question is do these advances in plant genetics mean that your produce Iowa soon include square tomatoes? Or pyramid-shaped pumpkins not likely says Vanja nap, but not because it's technically impossible. She says there are tons of bizarre mutations in the tomato. Genome that result in odds looking fruits and since those mutations are naturally occurring. They could be isolated and replicated in the lab, but the problem was square, tomatoes and other oddball. Shaped fruit is twofold. Internet says first there's the GMO problem if plant breeders use, gene editing to directly tweak or replace genes in food plants. Those strains are considered GMO and some people get freaked out by the GMO label, even though genetically modified organisms as category are no less or more safe than conventionally modified organisms. Second exciting new fruit and vegetable shapes may not shape up in other ways of Android apps said some mutations are so bizarre. That no grower would grow them because they have lots of other problems. They only have a few fruit per plant or they taste terrible. Because when you grow fruit in a really odd shape. You mess up the hormone balance, it may not be very juicy or tasty at all. If you really want to grow a square tomato says Vanja up just put a box round it like you may have seen done with other fruit. Like watermelons should those hit the scene at a premium price? You can always tried growing your own at home. There are plenty of instructions online for building your own square fruit boxes.

"cell division" Discussed on The Atheist Experience
"That's right DNA's like book except that it can copy itself. And it's not made of words. Right or paper. So thank reproduction and cell division. Okay. Herald camping I know where he is. He's dead. He's dead. So he was a small time wackadoo to minister predicting the end of the world twice for beat Italy repeatedly is so he's he was a proven fraud demonstrating via has follows the followers that a fool in his money are soon parted full in his money. We're lucky to get together. First place to go with the Harry in two thousand thirteen and the world is still going just fine. It's funny because the nice thing about Harold camping. Is that? He the last rapture that he'd had which was made fifth twenty eleven twenty twelve something like that. We he was out in the Oakland, California area. So I flew out to the Americas put on what was called the Oakland rapture ram and ram LA's regional atheist meet up, and so it was like a mini convention there in Oakland. And I was there with a great many awesome people, Greta Christina. And I pulled out the blow dryer into D baptisms wearing robes Keith little Jensen was there. That's where he and I first met mister deity was there as well. And the funny thing is is that in the evening in one of the later talks. I think it was right in the middle of of Brian, Mr. talk. There was an earthquake. So here we are in rapture day. And. We're gathered here and there's an earthquake. And it was one that you could actually feel that you know, it wasn't. It wasn't like a hey was that an earthquake? It was like. Oh, wow. That was an artist quake, not terrifying. Nothing, you know, fell down broke. But it was it was enough. And I'm not going to Keith joke because I don't still jokes. And it's funny. You should listen to talk about it. But people are got quiet this looking around. And that's when I yelled is that the best guy, and then we went on with the convention and Harold camping died. So. Yeah. Good story. Good story. Then there was as Jesus character. He he was a raving about the end of the world and delusions of grandeur, maybe and said he'd return and make and make predictions about the timing. But those predictions are failure they didn't happen. And he still dead end. He's been a frost profit for two thousand plus years if he ever existed his as far as we can tell he's not alive. Yeah. Yeah. So many of these famous Christians are just as oily as the ever were even when they're frauds frauds are exposed they keep going like the energizer bunny, and there's no real power within Christianity clean up the themselves or these fraud, so they persist and ultimately the belief is a fraud. And the in many of the people that promoted are working a scam. And these people are not going to lead you to attornal sell vacation. But they're just or turn bliss. Just playing preying on your ignorance, and that's another failure of Christianity. It's an interesting take on all of this. Because you know, there's other names you could've picked out. Yeah. There's a much larger list. But the thing that I find interesting is in, you know, here's Peter Popoff. Who's exposed as a fraud on live TV in a in a shocking way and ends up. I think bankrupt at least temporarily and is now back making millions of dollars a year with yet another scam. The same thing happened with Jim and Tammy Faye Bakker with Jimmy Swaggart. And his oh, let me cry until you house out. I was to have sex with those women. And and yeah, you you weren't sad to have sex. Sorry. That's a big fat lie. And yet he you know, he's back. It's they're like cockroaches..

"We want to invest more energy more of our our time. And you know, this is the trade off that was made Volusia narrowly in in. You are deep history that it makes more sense to stop growing in start investing in reproducing to make another copy yourself by combining with another person. So you know, it's still, you know, shocking to me after studying science for tennis years that it that this all works, but the it just comes down to that that we grow by cell division. We replicate removing we near the species propagates by cell division. It has to stop at a certain point in those that ability to stop is hard coded into our genome. There are many surpassed ways, many, many mechanisms by which your body tells the cells like, okay, we've finished growing. We don't need to divide anymore as an individual cell though. If remember that, you know, each of ourselves doesn't necessarily know that it's a part of a human in, like my goal is to, you know, survived. Go have a good weekend and then maybe reproduce someday. It's. To the cell just knows that it needs to divide to grow like any living organism. So these, these, these inhibitory pathways that really pre prevent Neo everything. All of those thirty trillion cells from all going their own individual way. And that's what you got to prevent the issue with cancers at, like I said, give those trillions of cells. And if just one of them. It figures out a way to get around those. Those roadblocks of the body throws up to prevent division that's enough to lead to a cancer that can eventually kill the the entire organism. Take all the other trillion cells with it. Really just one out of thirty trillion. So just wanted to start. Yeah, ends up being a lot more, but. Sneaky, bass. It's part of the problem right? Is that there's so many different types of cells in your body and then some of them like immune cells. They have to keep dividing in order to new, do their normal function. Other cell types, like the lining of your gut is dividing constantly your entire life and that's necessary for you a healthy metabolism. But, but you know, sometimes it goes awry and it can go awry in a lot of different ways because there are that so many different cells that it could happen, and that's what and that's where you get to the stage where you know the scientists suggest, they'll say that, you know, cancer is in one disease. It's a thousand a million different diseases which meet which makes it a little bit harder to cure then saying finding the the, the cure for a one specific bacteria. Right, right. Yeah, I think that makes a lot of sense. And, and you know, I guess we can get to sort of the more recent. Accomplishments in and discoveries. But you know, we, we know like I think the first. I sort of not cave drawings, but evidence of of cancer goes back to Egypt, but you know, four or five thousand years ago, but obviously a homo sapiens has been kicking around for a few hundred thousand years in on the species. Go back. Wait for the net like cancer is a new it must be dividing should has been going on for a long time..

"I at fusion must have happened. I in a few individuals and wouldn't inter wouldn't it interfere with fertility with cell division and so forth. And the answer turns out to be there is a slight effect on that, but it turns out and I'm going to take the easy part. I the closest thing that we have on this planet to a truly wild horse. Our horses in Mongolia, cold, press, Wolski, horse. All skis horse has sixty six chromosomes domestic courses Equis Kabbah. If you will has only got sixty four. Why is it that all domesticated courses again are missing a pair? Well, the answer is chromosome fusion and we can see exactly where it happened and it happened at some point probably in central Europe or Asia during the domestication of horses. So that's a very interesting thing. Now, here's the next thing. The argument that if this had happened in one of our ancestors, they wouldn't have been furtively wouldn't have left descendants. There are now two scientific reports of families with forty four chromosomes. At each case, it has resulted of a fusion between two chromosomes. The one I can recall immediately was a fusion between chromosomes fourteen and fifteen to form a single combined. Chromosome. This must have happened a couple of generations ago. The people are healthy, they're still viable and that shows that there's not a problem of mechanism here. Chromosome fusions in fact happened so common that there's a jargon term for them. They're called cold, Robert Sony and translocations. And they, they are well known in mice and other experimental animals, and it's not surprising that what happened in our industry as well. I'll be back in a moment. Hey, everyone. Thanks for sticking around. We were about to hear about a plant that supposedly saved the earth from staying hothouse climate. It was actually so hot that there were hippos in the Arctic. So lay it on us. Andrea. What was this plant that changed the world? The plant that seems to have driven. So much of this huge change is what you might call pon scam. It covered the Arctic Ocean soaking up mind-blowing amounts of carbon dioxide. And today, plant scientists are looking to a similar plan called duck weed to help control the climate. Once again, we don't have half a million years to do this, right, but we do have genetic tools..

"I mean we already touched on the greenland shark fin i think we've gone more indepth them agreement churkin in the past on the show but a part of it is it's environment which is quite cold okay uh he also commented on the connection between the sole in the body the sole must stand in a different case in respect of its union with the body and in this at least a rings true hints to all things are at all times in a state of transition and are coming into being and passing away oh okay so this could be interpreted to mean something kind of like the fact that were constantly undergoing cell division yet and our bodies maintain them i mean obviously aristotle did know this but that our bodies maintain themselves through cell division and repair of tissues yes and then there's this quote speaking generally the longest live things occur among the plants example the date palm next in order we find at them among the sanguine us animals rather than among the bloodless and among those with feet rather than among the denizens of the water hints taking these two characters together the longest lived animals fall among sanguine us animals which have feet men in elephants will clearly we've learned how to make your aquarium fish live longer you transplants feed on to them this is at least as good quote as a matter of fact also it is a general rule that the larger live longer than the smaller for the other longlived animals to happen to be of a large size are also those i have mentioned now i'm sure this is not a hard and fast rule though i think there are probably some week correlations along these lines address serving we already touched on the dinosaur thing but that but certainly there are some examples of rather large animals that have longer lifespans within typical longevity yeah now air cells working theory though is that all of it revolves around moisture in an organism yes quote we must remember than an animal is by nature human and warm and do live is to be of such a constitution while old age is dry and cold and so is a corpse i think aristotle also tried to explain earthquakes by way of moisture and i may be miss remembering of.

"Dear mom i'm sorry i'm sorry for manipulating you stealing from you and ultimately taking control of your blood supply there i was a harmless single foulds i go just happily floating around your uterus i did some cell division to pass the time and then five or six days later a hit a wall by then i was a blast at this and i did what anyone in my position would do really a cosied up to your uterus involve sounds nice but truthfully back then i was a little bit of a pera say a use may outer layer of cells like ravenous snakes and embedded myself into your body and that's what i got the the sucking up oxygen delivery next those outer cells of mine called trophy blasts grew into clumps that fused with your blood vessels our blood never mix but i made countless chambers and filled them up the blood inside with yours the tissue that held up blood all mine and together that tissue and all those blood spaces became one of the strangest and in most fascinating oregon on earth a placenta imagine that months before you and i bonded out here in the world we shared in oregon i grew wrigley little bloodvessel projections bright into those big chambers of your blood so i could pass my waste out into your bloodstream so even then you had to clean up after me a little bit later i got demanding i really started in your blood supply for most animal species moms blood vessels remain safely hers but humans we are ruthless so slowly may cells begin taking control of some of your arteries a wide in them to get more blood more oxygen more nutrients after that are placenta started pumping out all sorts of hormones way before baby talk you and i had a kind of chemical communication so i could let your body know what i needed and this is where things gut day some of those chemicals lowered your blood pressure and increased your blood sugar you could have developed jurisdictional diabetes at best i probably made you a little a headed that worst i could have killed us both.

"And how researchers to find meaningful as where things start to get interesting you see human dna contains gene mutations these are permanent alterations medina sequence that makes up a gene mutations can affect a single gene or even groups of genes and mutations are either inherited or they occur at some point during a person's life either from environmental factors like uv radiation from the sun or during cell division when dna copies itself and makes a mistake when these mutations happen and important sequences they are more likely to become harmful than beneficial and when we have kids some ever dna mutations are passed on kids with the collection of particularly bad mutations are more likely to die before having children of their own this is evolution way of ensuring that those bad mutations aren't passed on it's also why today most disease causing gene mutations are uncommon and the general public and this is how evolution stops bag mutations building up to dangerously high levels in species and this is where the researchers logic came in if most of our dna were functional we would accumulate a large portion of harmful mutations in very important sequences is just a matter of math to test this majority functionality theory researchers from the university of houston calculated how many children a couple would need to conceive so the evolution could still weed out enough bad mutations for merge genomes and it's a lot if an entire genome were functional couples would need to have around a hundred million children and almost all of them would have to die this of course is absurd but let's say that even a quarter of our genome was functional each couple would still have to have an average of four children with only two surviving into adulthood to prevent harmful mutations building up into these dangerous levels luckily this is not the case.
