"Drivers will spend hours in traffic, especially in midtown. Shockwaves without the University of Virginia college campus tonight after the deadly shooting of three UVA students were college football players. The gunman who allegedly shot them at near a parking garage area identified as UVA student Christopher Don Jones junior police say Jones was arrested this morning. University of Virginia president James Ryan identifying the three students were killed. They were Devin Chandler, a second year from Virginia Beach, Virginia, lavelle Davis, a third year student from ridgeville, South Carolina, and deshaun Perry, a fourth year student from Miami, Florida.

Listen to this podcast now on the red Apple podcast network. Let me tell you hosted by the First Lady of New York radio show Hamburg. I'm talking to Andrew Paul, who's a movie you should see. I'm a gadget time. What happened along the way to James gray, where he had to make this film. He brought his kids back to flushing to sort of drive around and show them the old neighborhood. And they got the idea of wanting to do something super personal. And the issues in the movie felt very unfortunately, very present today in 1980, something changed in this country where we went from the end of the 70s and the free speech movement and civil rights and public health watershed moment to him when we went to a more materialistic play and morality is going by the wayside and then he felt like to tell that story would be really resonant today.

"2022 would be 2022. It's massive considering where sporting Kansas City are. In the league play, nightmare. Could you salvage it? You could. With a cup with a trophy. This is always that, yeah, we didn't do this so well, but we got this shiny object right here. This is the cop that we won. So literally your season is gonna be chalked up to can you win the U.S. open cup 'cause it's been so bad in Major League Soccer and we know how things can change. You get a player in the summer that can change things around, maybe a couple and sworn Kennedy's case they need they need a few. I don't anticipate that happening. So you really have to put all your eggs in this one basket, which is U.S. open cup. Now, reminder that they won a huge open cup round of 32 game against Dallas, which felt like a changing moment, and then they went and lost the Portland 7 two that weekend. So I think Jordan Morris Freddie Montero and Christopher Don might be licking their lips because they host sporting KC on Saturday at 3 p.m. Eastern Time on ABC, sporting KC also officially signing William agada from hop oil Jerusalem, which we've talked a bit about 22 year old striker. This feels again like they're trying to get younger. They signed three under 22 players in this off season to sort of fill in at left back center back in winger. They sometimes play, not that much. So maybe it'll be different here with William agata but congrats to sporting KC to their fans and they will know when the show comes out if they're hosting or traveling. Foreign open cup semifinal either way sounds like a great time. I wish that I could be there. Let's move up to Canada, the semifinals already done in the Canadian championship. We are headed to a final, the Vancouver white caps will host Toronto FC, sometime in July, this is a big moment for the Vancouver white caps. It's a big moment for I think both these coaches Jordan, when you look at vanny sartini in year two and bob Bradley in year one, what would winning this competition mean for those two guys? Well, yeah, it's been a rough beginning to the season..
Nature Docs Avoid Habitat Destruction
"This is scientific Americans sixty seconds science. I'm Christopher Dodd Yata. Documentaries are known for their sweeping natural vistas. This does their amazing footage seriously. How did they get that shot in often soothing baritone of Sir David attenborough strain incontinent what those documentaries don't do though is show the realities of environmental destruction historically particularly BBC documentaries have shied away from that Nikki Rust is an environmental social scientist at Newcastle University in the UK Russ studied work by the BBC in the World Wildlife Fund which had teamed up with Netflix to make what they said would be a whole new kind of production. They wanted it to reach. I think a billion people and that it was going to revolutionize nature documentaries except for the fact it may be that attenborough would be the narrator the Netflix series our planet aim to be different because it promised to reveal the threats facing wildlife in the natural world so did it deliver liver rust and her colleagues analyzed scripts of our planet along with three recent. BBC Series Planet Earth to Pimple Dynasties Twenty into hyenas and Blue Planet to spider cramps and logged everything they saw on the screen turns out planet only talks about threats and successes successes a bit more than Blue Planet to fifteen percent of the script did focus on the woes of the natural world but very little devastation was actually shown on screen. The spite being filmed the analysis is in the Journal people in nature. The lead author of the Study Julia Jones was in Madagascar at the time where net that flicks were there filming and she knows that they were there filming the destruction of Habitat and burning and lots of mental devastation so they've got fatigue is just unfortunately it wasn't chosen to be included. It's not clear if that's really a bad thing. Though we still don't really know whether showing environmental tragedies on screen green motivates people to support conservation but what climate change communication has taught us. Ross says is that the ideal way to motivate audiences is with optimism tinged with trepidation. Thanks for listening for scientific American sixty seconds science. I'm Christopher Don Yata.
Andrea Townsend, Christopher Don Yada And Christopher Dodd discussed on 60-Second Science
"This is scientific. Americans sixty seconds science. I'm christopher dodd yada. Cholesterol affects one third of american adults but it's not just us studies have indicated they cholesterol is also on the rise in other animals and in all of these studies that idea was well they hypothesized that was probably due to interactions with people and eating our food but they didn't actually show that andrea townsend is an avian ecologist at hamilton college and upstate new york and and she found that crows did have higher cholesterol then rural crows but then she took the next logical step in her research she went to mcdonald's we'd pick up one hundred and twenty-five twenty five burgers at a time once one of them wanted to know what we needed all these burgers for and then i started to explain they just kind of waved me away halfway through so of course she needed all those cheeseburgers to feed the crows and to monitor their diet to determine if eating are fast food really does raise the birds cholesterol so the way you supplement your nestling is we'd go to their nest trees and we toss the cheeseburgers three a day predefine day under their trees and then the parents immediately swoop loop down pick up the burgers and bring them to the nestlings and as you might expect crows that dined on cheeseburgers did indeed have higher cholesterol than cros who did without but here's the surprising thing higher cholesterol didn't actually affect crowe's chances of survival over a three year period in one population birds with higher cholesterol were arguably googly in better condition than other crows meaning chubbier. Their results are in the journal. The condor crows can live more than fifteen years and townsend says maybe maybe a high cholesterol diet makes its mark later in life as humans and if you're still wondering why study this i would say this is an important question because there are are lots of other species that also live in urban areas and eat our food and some of them are endangered so it isn't important question how will our food affect the health of wild animals and as we urbanize more of the globe our dietary influence might have even wider effects as for townsend grows are known to be highly skilled it recognizing humans and she says the study made her a celebrity during the study especially when i was walking around the crews would follow me around campus. They often just just follow me around campus anyway they follow my car and then i was getting some notoriety on a broader scale with cros so i would go into getting gas and the crows on the gas station would be calling a special car. Yeah i think just for me and it seemed like a recognition call after after all a free lunch sure does seem like something to squawk about.

London Crawling with Drug-Resistant Microbes
"This is scientific Americans sixty seconds science. I'm Christopher Dodd Yata. If you're a Germaphobe navigating the city there are certain certain mandatory rules of engagement use a paper towel to shield your hand as you touch the bathroom door handle lift toilet seat covers with your shoe touch buttons at A._T._M.'s and crosswalks awesome walks in elevators with a knuckle. The back of your hand never a fingertip. I know this because I am that person and a new study in the journal scientific reports somewhat justifies is my behavior because when researchers in London sampled all those kinds of surfaces in public shopping centers and train stations and common areas in hospitals what they found was a whole a lot of antibiotic resistant bacteria lurking there scientists swab sites all over London and ended up with six hundred samples of staphylococcus bacteria of those nearly half were resistant to two or more commonly used antibiotics like penicillin and Erythromycin and the hospital samples had significantly more drug doug resistant microbes which makes sense because hospitals are a place where they use a lot of antibiotics but if there is a silver lining here it might be how few staph bacteria were multi-drug-resistant drug-resistant in public places a mere forty seven percent because a few years back one in the same scientists swabbed London hotel rooms in found that eighty six percent percent of the staph bacteria. There were multi-drug-resistant which may not help you sleep easy. Thanks for listening for scientific American sixty seconds science. I'm Christopher Don Yata.
Scientist Encourages Other Women Scientists to Make Themselves Heard
"This is science Americans sixty seconds science. I'm Christopher Dodd if you attend science conferences, ever pay attention to who in the audience asked questions, geneticists Natalie, tell us did. And she noticed something off the entire first day of the conference. I was the only woman to ask a question, and I thought, wow, that's kind of weird. Right. So being a scientist she decided to systematically study who ask questions at scientific conferences together with colleagues at Stanford University where she was based at the time and others at Emory University in Atlanta, she recorded more than two thousand questions from hundreds of talks at eight different scientific conferences, after assigning, either male or female, designations to question asker, which the researchers acknowledging the paper doesn't fully capture the spectrum of gender identity. They found that women ask far fewer questions than Representative result based on their numbers. In fact, you need about eighty five two. Ninety percent of your room to be women before fifty percent of your questions. Come from women, but tell us did identify a possible solution halfway through the biology of genomes conference in two thousand fifteen tell us started tweeting, some of her preliminary findings about how few women had been asking questions compared to the relative numbers at the meeting that information sparked a public discussion and policy change from the conference organizers who instituted a new rule that the first question at every talk had to come from scientists still working towards her PHD in the hope that, that approach would produce a more diverse set of question asker, and it worked before our intervention about eleven percent of questions came from women, which is one third of what you'd expect after our intervention. You get more like thirty five percent of questions. Coming from women, it's actually what you'd expect from that audience, the analysis is in the American journal of human genetics and tell us says that strategy of simply publicizing the. Problem has been effective at other conferences to getting more women to not only attend, but to participate in scientific conferences, a lot of women have messaged me and said, oh, you know, I asked my first question at a conference when I saw this work or stuff like that. And I hope that, that means that people are taking advantage of that, incredible opportunity to really add their voice, not just their face in the conference photo to that scientific community.

Scientists Fool Flies with 'Virtual Tastes'
"This is scientific Americans sixty seconds science. I'm Christopher Dodd Yata. There's a scene in the matrix, where the character cypher talks about the illusory experience of eating a fine meal. I'm Ben you on the steak and he said, I know this doesn't exist. I know that when I put it in my mouth, the matrix is telling my brain that it is juicy and delicious taste so good. I prefer virtual reality to the cruelty of the world. Ignorance is bliss. Recounting that scene is Carlos Ribeiro, a neuroscientist at the Champalimaud foundation in Portugal. He has a special interest in that scene, because he has essentially recreated that phenomenon in fruit flies who did exactly doing to the flash. Here's how it works. He and his team raised genetically engineered flies, with tastes neurons, that can be turned on and off with red and green light that kind of process is known as Octo genetics. His team fed the flies bland food, which they understandably disliked. But then the researchers made the flies in light to turn on sweetness perceiving neurons and the flies gobbled up the food, which to them now, tasted sweet. The team was also able to do the same with bitter, neurons flies got bitter food, which they avoided, but the scientists then turned off the bitter neurons, and all of a sudden, the flies changed their minds until we have used this to create completely virtual tastes reality for our flies. The experimental. Details are in the journal. We live. So why do this? We really want to understand how the brain uses sensory taste information to make feeding decisions. And also, what goes wrong in a beef for example, or when there are other diseases, which are related to nutrition. He also imagines we could someday use, gene therapy techniques to plug senses back into the noses or tongues of people who've lost the ability to smell or taste, but for now that is like the matrix firmly, the realm of science fiction.

Wheat Plants "Sneeze" And Spread Disease
"This is scientific Americans sixty seconds science. I'm Christopher Dodd Yata, humans can spread disease by sneezy, but less well known is the wheat plants ability to do something strangely, similar from its leaves basically analogous to humans me is in terms of you have very fast and sudden expulsion of droplets that contained the disease or pathogen inside of it. And they kind of thrown away from the surface Jonathan burrito. A mechanical engineer at Virginia Tech, he and his team were studying the ability of wheat plants to expel spores of a common pathogen the wheat rest fungus from their leaves via this unusual mechanism. So the inoculated we'd plants with the disease created do on the plants leaves, and then studied the ensuing action with high-speed microscopy. Here's what they saw the leaves are extremely hydrophobic meaning water beads up to minimize contact with the surface and win two or more jobs, touch energy gets released in the form. Of catapulting action, which sneezes the droplets into the air several millimeters above the leaf surface. The droplets can then be picked up by light breezes or simply fall and spread to other plants. The process is surprisingly effective, at launching spores. The researchers figure each leaf can launch a hundred spores per hour during a morning, do the results and photos of the jumping drops are in the journal of the Royal Society interface. Next break oh and his team want to see what happens if they spray stuff on the leaves the changes the way do forms for if we painted a wet ability of the lease, but they're no longer super hydrophobic now to do drop will be unable to jump when they grow. They sort of claim to the leaf surface and not be something anymore. Such treatment could perhaps put a stop to wheat sneezes and slow down the transmission of disease.

Antiperspirant Boosts Armpit and Toe-Web Microbial Diversity
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata. A lot about how what you eat will affect your microbiome. Probiotics prebiotics stuff like that. But your skin is swarming with microbes to and the grooming products, you use might affect what's living there? That's according to a study in the journal EMC biology further tests. Researchers recruited six men and six women, the volunteers left their skin alone for the first three weeks except for a light body wash and then for the next three weeks, the participants apply to modern skin-care arsenal. Sunscreen and skin lotion into perspiration and foot powder. Finally, the volunteers returned to their usual routine. Whatever it was each person for another three weeks throughout that time. The scientists swabbed volunteers faces in forearms, armpits and feet. And they did chemical in genetic analyses of the samples, the lotion, and sunscreen, did not appear to alter the microbiome, but they found counter-intuitively that the anti per sprint and foot powder, actually boosted the diversity of microbes in the armpits, and in between the toes. Perhaps, because those products change nutrient and moisture levels and thus create conditions that foster a wider variety of tiny occupants. The researchers also found that different skin care routines, altered, the types of hormones and fairmont's present on the subject skin. And they hypothesis that someday personalized skin-care recipes could be tailored to individuals to alter our Ramones in a systematic way thus making us more attractive to others or less attractive should anyone need to lessen their Kevorkian.

High School Cheaters Nabbed By Neural Network
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata, the English language version of Wikipedia has almost six million articles. And if you're cheating student that's six million essays already written for you footnotes and all except plagiarism isn't really ineffective tactic just plug the text into a search engine and game over. But what about having a ghostwriter at a paper mill composer final essay, STAN dot K two recent software cannot detect this kind of cheating. Stefan luanne is a data analyst at the university of Copenhagen in Denmark, where he's based ghost writing is a growing problem in high schools, so Lawrenson and his colleagues created a program called ghost rider that can detect the cheats at its core is in neural network trained and tested on a hundred and thirty thousand real essays, from ten thousand Danish students after reading through tens of thousands of essays label as being written by the same author or not the machine taught itself to tune in to the characteristics. That might tip off cheating, for example, did a student's essays share the same styles of punctuation. The same spelling mistakes were the abbreviations, the same by scrutinizing inconsistencies like those ghost rider was able to pinpoint cheated essay nearly ninety percent of the time, the team presented the results at the European symposium on artificial neural networks, computational intelligence and machine learning. And there is one more aspect here that could help students your high school, essays presumably, get better over time as you learn to write and the machine can detect that the final idea is, of course, to try to detect students who either at risk, the because that development and writing style is not as you would expect teachers could thus give extra help to kids who really need it while sniffing out the cheaters too.

Preserved Poop is an Archaeological Treasure
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata for a longtime archaeologists have dug for the shiny stuff the sorts of artifacts that belong in museums. They like poach. They like jewelry and gold and stuff like that appears Mitchell, a biological anthropologist at the university of Cambridge Mitchell spends his time looking for something decidedly different from such handmade relics that thing he seeks preserved piece of human feces, copper lights as they're called are dried or mineralized pieces of poop and Mitchell and his team found some prime specimens in a trash heap at the ancient settlement of cattle Hoya. That's in modern day, Turkey and dates from six thousand to seven thousand b c Mitchell's team ground up the poop samples with a mortar and pestle then dissolve them and use Microsoft's to filter out particles of various sizes, the presence of certain molecules tip them off that it was indeed human. Poop in two of the samples, they found the intact eggs of whip worm and intestinal parasite that's far more likely to. Flourish in settlements than among people who poop and then move along down the road to a new location. The discovery thus gives us a glimpse of how human health may have changed as hunter gatherers started to adopt a stationary agricultural lifestyle. It's only by looking at these earliest villages. These earliest towns that was set up in the Middle East that we can really start to understand how when humans change their lifestyle to different way of getting food how it could increase or decrease their risk of different kinds of diseases. The results are in the journal antiquity and the findings prove that ancient poop is flushed with details about ancient civilizations.

Music May Orchestrate Better Brain Connectivity in Preterm Infants
"This is scientific Americans sixty seconds science. I'm Christopher Dodd Yata fifteen million babies are born prematurely, every year worldwide in some cases, the early births can be life threatening or cause developmental issues. They have more attention deficit difficulties. They can have a higher risk of having autism, and in general, sort of socio emotional regulation issues, patriot who appear attrition and neonatologist at the university hospital of Geneva now she and her colleagues have evidence that a simple tool could help those Preterm babies brains develop music. But before you queue, the Amadeus, I felt about multifold. This is very complex musical structure, and I could hardly magin that such a immature brain would be able to fully capture the complexity of Mozart, so instead, she recruited the harpist Andrea's, vol- inviter, who worked with neonatal nurses to determine which sounds would most stimulate infants brains. He then composed the suite of three eight minute long tracks, which the nurses played twenty Preterm babies using wireless headphones embedded in little baby caps. Each baby heard five tracks a week for about six weeks on average then hoops team used MRI's to visualize activity in the baby's brain's, and what they found was that premiums who listen to tunes had brain networks, that more closely resembled, those of full term babies compared to their counterparts who didn't get the treatment, the music listeners had greater connectivity among brain regions, such as areas involved in sensory and higher. Order cognitive functioning, indicating that music listening might have enduring effects on brain development. The details are in the proceedings of the National Academy of sciences. Of course, many questions still remain. I'll watch dilation to that was stimulation, given the right way would be much better. If it was. Something more lively than the recorded music was too simple. Or could it be more complex, but hoop? He said, one thing parents can already do his sing to their children. Plus, she said it doesn't really matter if you can carry it too.

Icy Room Temperatures May Chill Productivity
"This is science Americans sixty seconds science. I'm Christopher Dodd yada, a few years ago, scientists determine that our thermostats are sexist namely. That office. Climates had been optimized for a hypothetical room full of forty year old hundred fifty pound men using standards developed more than fifty years ago, and that ends up leaving a lot of women in the cold, call the ballot thermostat, right? Tom Chang, a behavioral economists at the USC Marshall school of business, he says, it goes beyond comfort for women. It seems that it's not just a matter of comfort. But it also affects their productivity Chang, and his colleague tested that link between temperature and performance by quizzing five hundred forty three German students on basic addition skills, and word scrambles in rooms that varied from sixty to ninety degrees Fahrenheit. And if you went from, let's say, the low sixties to the mid seventies, you saw an increase in female performance of almost fifteen percent, one five not five zero which I found. Markedly large as much larger than I had expected the effects tapered off after the mid seventies. But men on the other hand had a small decrease in performance about three percent as temperatures rose to the mid seventies, the results are in the journal plus one and there's a chance. These findings might explain things like disparities test scores on the SAT the longstanding gap in performance between high school boys and high school girls on the map portion of the SAT's approximately four percent. So given the effect size refinding. That's three degrees. Difference in indoor temperature still, he says, I wouldn't go running off writing policy off of one study. But it seems Cynthia Nixon had the thermostat dialed in just right last year. The actor turned politician was preparing to debate Andrew Cuomo as vita for the democratic nomination for New York state, governor debate venues are usually kept pretty chilly.

Ancient Gum Gives Archaeologists Something to Chew On
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata. You're probably not too interested in what some people call. ABC gum already been chewed, but for archaeology such gum as long as it's really old is genetic gold mine. It's bit. Like, I guess Jurassic Park Italia. 'cause Shuba a graduate student in archaeology at oops. Ali university in Sweden, she's referring to that famous clip from the movie about how Jurassic Park scientists extract blood from a mosquito trapped in amber being Dino, DNA, except in this case, it's human DNA and it's not trapped in amber. But inside exceptionally old chewing gums found at the site of an ancient hunting, and fishing village on the west coast of Sweden. The samples look like chewed up wads of modern day gum, but don't think Wrigley's, this detritus is black sticky. Tar distilled from birchbark 'cause Shuba has tasted modern day version sin isn't eager to try it again. Liz, I'm faith for it. So why chew on something so unpleasant? Maybe because they're gum wasn't for fresh breath. It could use it to seal your boat or like seal your thoughts. So it's kind of everyday use substance, many of the gums have teeth marks too. So perhaps, they chewed it to help shape it and intern develop. A habit despite the taste that today's tobacco chewers might relate to 'cause Shuba team extracted and sequenced DNA from the ancient gum, and they found genetic evidence of three different gum chewers two women and a man. It's the oldest human DNA found in Scandinavia dating to about eight thousand b c and because it more closely resembles the DNA of hunter gatherers from western Europe than from eastern Europe. It also provides hints about how people ended up in what's now Sweden the results are in the journal communications biology. The gum could still hold other clues about ancient diets or the bacteria. These people had in their mouths so given that we can learn so much from chewing gum. Is it really that bad to stick it to the bottom of chairs and tables, you know, for the benefit of future? Archaeologists still think that one should not without any place just like that. So I think you should definitely throw it in the but I won't blame these guys who who spent as out to those years ago.

Penguin Poop Helps Biodiversity Bloom in Antarctica
"This is scientific American sixty seconds science.

Steph boekhorst is an ecologist at via university in Amsterdam in the initially white stuff. He's talking about is penguin poop to firstly notice of it is the smell, basically, you're squishing. True. Puddles would you I guess mouth? But it's actually just poop and up producers that really strong ammonia smell 'cause you can really smell from for miles away. But it's not just the smell that travels on the wind ammonia contains nitrogen a- valuable fertilizer. So the winds carry nourishment to nearby mosses and lichens and that in turn supports teaming communities of the largest fully terrestrial animals in Antarctica, invertebrates, like spring, tales, and mites. Boekhorst and his colleagues took air and plant samples around the poop piles and. I found this airborne ammonia fertilizer enriches life as far as a mile away. The full details are in the journal current biology in the work makes it easier for scientists like bow course to remotely estimate in articles biodiversity, they don't have to go to all these different field sides. You can actually basically sit at home. Take these pictures with satellites and then get an idea where the highs by the should be along the peninsula. Of course, doctors have long taken a stool sample to get medical information about a patient, and now ecologists will be able to use imagery to track feces and predict it's beneficial effects at the bottom of the world in short don't pooh-poohed the PU.

U.S. Coral Reefs Do $1.8 Billion of Work Per Year
"This is scientific American sixty seconds science. I'm Christopher Dodd Jatta. A physics lesson may be the last thing on your mind, as you relaxed the ocean. However, if you're sitting on a lovely Hawaiian Bj with your mind tie, and you're looking off shore, and you see twenty foot waves and people surfing on them. And you notice that it's only lapping up on the shoreline here with teeny little waves. That's the reef working to dissipate that energy, Mike Beck. Studies. The intersection of engineering ecology economics and finance at UC Santa Cruz. And he says reef sacked a whole lot like our human built coastal infrastructure to tame the energy of incoming waves. They essentially act just like a low crested submerged breakwater, that's an engineering term. But it means that they're really good engineering models for describing the benefits of res and those models are the key behind a new report from the US Geological Survey with Beck is one of its authors. The. Researchers modeled hypothetical storms hitting coastlines in areas with off shore reefs like Florida Hawaii and Puerto Rico they studied how reefs of various heights would dampen waves and holdback flooding, and they found that every year the country's reef save the US estimated one point eight billion dollars in direct flooding damages and other economic losses that dollar numbers important because it allows reef rebuilding projects like gluing little healthy coral nub ins, undamaged reefs to tap into billions of dollars of federal money set aside for hurricane in disaster resilience, if you can rigorously value, the benefits of any of these habitats you can unlock any of the funding mechanisms that would have typically been applied to developing a seawall or a breakwater.

Could Air Conditioners Help Cool the Planet?
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata air conditioning and fans account for a full ten percent of the world's electricity usage or to put it another way. Not of that you pump around rolling did Meyer, a chemical engineer at the Karlsruhe institute of technology in Germany and other thing that takes a lot of pumping air around. He says carbon capture because the concentration of CO two in air is evidently, quite low even though it's enough to cause climate change. It's only four hundred parts per million. So he says why not retrofit air conditioners with modules that capture carbon several companies already make materials that strip carbon dioxide from the air you then need to convert that captured CO two into hydrocarbons, that's an energy intensive process. But didn't Myers vision is that we'd use clean carbon-free renewable energy to power that step do this on a large enough scale, and you could produce significant amounts of this synthetic renewable. Oil did Myron his. Colleagues calculated that if you outfitted the AC system of the fair tower, a large skyscraper in Frankfurt with these carbon capture devices, the buildings units alone could produce an estimated fifteen thousand barrels of synthetic oil a year the full right up in the journal nature communications is called crowd oil not crude oil. And if the idea gets traction, it could transform the devices that cool our homes and offices into machines that help cool the planet, or at least stop warming it up while chilling us down.

New Model Aims to Solve Mystery of the Moon's Formation
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata on July. Twentieth. Nineteen sixty-nine humankind. Finally, set foot on the surface of the moon fifty years later, a big mystery remains how the heck the moon got there in the first place for decades the thinking on that has been that four and a half billion years ago, a Mars sized proto-planets smashed into the earth when the dust settled our moon remained forged from the debris of earth and that other object. The problem is as scientists have taken more and more precise isotopic measurements of the moon. They've found that it's nearly identical in composition to the earth. Not some other object a problem that I've been advertising as a nice topic crisis. Jamie Losch studies planetary impacts at Purdue University. Now, he says a new theory in the journal nature geoscience may at least point to away out of that isotopic crisis of the moons. Chemical isotopes so closely resembling earth's here's the idea. The authors a team of Japanese scientists right that maybe in those early days of the solar system. The earth was sloshing with oceans of magma, then when the Mars sized objects slammed into those Moulton seas their models predict a lot more earth derived material gets injected into orbit in the form of scorching vapors temperatures of tens of thousands of degrees. And so that expands at speeds that exceed the escape velocity of the earth, and in that way, injects material into orbit around the earth that material rapidly coalescence and bingo you've got a moon. Malaysia says there are still a few kinks to work out in the scenario. Still. He says it's a step forward. Think of it as a major clue in a murder mystery or something like that it could be true clue toward the answer. Could be of the -ception. We don't know yet. So it could be that we Nastro naught started walking on the moon and a half century ago. They were really leaving footprints on the remains of the primordial earth.

River Dolphins Have a Wide Vocal Repertoire
"This is scientific American sixty seconds science. I'm Christopher Dodd Yata.
