From the tisch wnet studios at Lincoln Center in new rerk, hariivasan. Sreenivasan good evening, and thanks for joining us. Barry brought its heavy rain to louisiana today as it moved very slowly out of the gulf of mexico and onto land, briefly becoming a hurricane before turning back into a Tropical Storm. The storms winds reached 75 miles an hour, making it a category one and the first named hurricane of 2019. It was downgraded to a Tropical Storm within hours, as its wind speeds dropped after making landfa west of new orleans. But, it was the rain, not the wind speeds, that caused evacuations and preparations for days of possible flooding. Water flowed over the tops of some levees, but as of the afternoon, no levee breaches have been reported. This afternoon, officials said the Mississippi River is now predicted to peak at 17. 1 feet on monday, below the 20foot levee height. But, Governor John Bel Edwards continued to warn residents to stay home or go to shelters, telling them the first hours are just the beginning. Forecasts show as much as 25 inches of rain from barry could bring lifethreatening flooding across eastern louisiana and mississippi. Dre moreau is anchor and managing editor for Louisiana Public broadcastings statewide news magazine show, the state were in. He joins me now from baton rouge. Were chatting saturday afternoon what do we know about this storm right now . Well, we know that the storm has lived up to the frecast, soa far, but tht its done it in its own sweet time. Its hours late but it did become a minimal hurricane at 75 miles an much of the storm, though, is still offshore. T all e huge rainmaking clouds are offulshore in the of mexico, so, as its coming in on shore and making its landfall, the drier part of the storm, but the real wet part of the storm, what people in baton rouge and new orleans, but baton rouge perhaps more so, are so fearful of bcause there are forecasts of rain, people are saying 10 to 20 inches, up two feet, and, if that happens anywhere in a short ount of time, youre going to be in trouble, and its sort of like a harsh memory from the floods of 2016 when ere were 25inches of thraint fell in a day and a half and a lot of people have never gotten back in tmes that were destroyed from that time in metro baton rouge. Sreenivasan tell me about what happens in those fir o coupdays taf after the rain when a theibutaries soak the water up and feed into rivers . What happens is that the water just rses and it can inundate homes, as it did in the flood of 2016. But, as you saw in other hurrices where flos have been the big story and thats what this big story for barry would be its theater, not so much the the wind, and thats the fear. Bu you know, its a matter of you cant do anything till thats water goown, and then the real trouble begins because youve got homes that have been soaked in water that s dangerouit has to be cleaned out, dry wall removed, if the home is hill one tat can be saved, and thats a process. It takes aong, long time. So its something that people dont want to think about. You know, its a horrie thi to think about. Its a reality in this pa the world, and its something that i think people are prepared for this time but are just hoping it doesnt get to that level but are ready for it. Sreenivasan speaking ofar the prions and speaking of how its part of life there, how cuny people are eving just to get out of harms way . How many people are deciding to de out the storm . How do the local authorities deal with that . Well, they look at the most disaerprone area, so ther are two parishes that have been out of mandatory evacuation, laquemines parish which feeds down thessissippi delta, the last part of louisiana where much of it isiminishing anyway, and then parts of jefferson parish. Other parishes are under voluntary evacuations, though. So in terms of massivex eodus evacuation, you have not had that for th, t there are shelters set up in place in alexandria, louisiana, for example, for people if they need to go there. They get ready cfor this beause theyve goat through the drill so many times before and knows the drill so were doing what we know how to do. Srerenivasan andre eau of Louisiana Public broadcasting, thank you so much. All right, than you. Sreenivasan for the latest on barry and its impact on the gulf coast, visit www. Pbs. Org newshour. Sreenivasan on a t border detention facilities yesterday, Vice President mike p with hundreds of men being held in a concrete and chainlink enclosure in mcallen, texas. There were no cots or mats, haly mylar blankets, and the men shouted that thenot had showers for weeks. The agent in charge confirmed that many had not showered in ten to0 days because the facility only recently added a trailer th showers. Many of the nearly 400 men were shirtless d reporters said the room was hot and foulsmelling. After seeing the conditions, pence told reporters he was not surprised and that he knew hesy would see em that was overwhelmed. Earlier, pence and his wife toured a facility for children and families in donna, texas, where he praboed customs and er protection agents in their care for families. After the trip, pence tweeted that he toured the facilities to show that the migrant crisis is overwhelming our system, and blamed democratsor the situation, saying that the men were in a temporary holding area because democrats in congress have refused to Fund Additional bed space border officials said the longest any man was held in the overrowded concrete and chainlink pen was 3. Thousands of people turned out last night and today to protest immigration and Customs Enforcement raids planned for tomorrow. In chicago, immigration activists held a rallyng proteshe raids. In colorado, near denver, which is one of the nine cities wheret immin raids are expected tomorrow, demonstrators gathered outside an ice detention facility. And downtown los angeles, thousands of people held a r ndlelight vigil. The group lights berty organized the event, and an estimated 800 other candlelight protests across the country.

Reenivasan as part of our ongoing series, the future of food, were taking a closer look at cellbased meali bestsel author and food expert mark bittman hosts the series, and has more on that story. Bittman with all the concerns about the ethics, Environmental Impact and sustainability of meat production, many people are looking for alternativ by now, youve probably heard about the surge in populity in burgers made solely from plants. Even burger king plans to serve one in all of its restaurants. But could it be possible to grow what amounts to real beef or chicken in labs with no animals killedn the process . And could such a process actually be sustainable . It may sound like science fiction, but Megan Thompson traveled to california, where a few companies were working to get labraised meat on your plate in the very near future. This report is supported in partnership with the pulitzer center. Eporter in 2005, uma valeti was an upandcoming cardiologist in st. Paul, minnesota. Hed just finished a prestigious fellowship at the mayo clinic and was treating patients with serious heart conditions, all while conducting cuttingedge research. In my practice in cardiology, i started working on this Clinical Study that took stem cells of patients that had larga heart s or cardiac arrest. And we would take those cells and inject them into patients arts to regrow the heart muscle. That led me to start thinking, can u just grow food from cells . And once the idea got into my head, it was really impossible to get it out. Reporter valeti started researching the idea of creating meat in a lab. Hed always been bothered by t Environmental Impacts of meat production, and also the fact that billions of animals arer slaughtered at each year. It really started dawning on mehat all the pieces of wh we needed to do existed in the world. And we had to put it togppher for thiscation of growing food. Reporter valeti walked ay from his promising cardiology career and moved his family to the San Francisco bay area to pursue the idea of creating whats known as cellbased meat. In 2015, valeti launched memphis meats, one of the first private companies in the world focused on the technology. The next year, memphis meats debuted its first product. It tastes like a meatball. Reporter valetis labgrown meatballs take only a few weeks produce. A beef cow, by comparison, takes around 18 months to get to market. Leti believes his fastgrowing meat could help address the issue of increasing demand. With the middle class growing around the world, Global Demand for meat will double b, according to the u. N. Were at a breaking point where i think if this demand for meat continues in the way it is, there just isnt enough resources for it. Thats kind of why i think the the whole thing requires massive innovation. Reporter valeti also talks about one day creating healthier meats less likely to cause the Heart Disease he saw in so many of his patients. Today, memphis meats has closeee to 40 empland is working on duck and chicken, which vale gave me a sample of. Okay, here i go. Go for it. Reporter its very tender. Yeah, theres definitely no way at i would, if you hadn told me, that i would know this was grown in a lab and that it c didne from a conventionallyraised chicken. Go it taste, and it even had the fibers youd expect. But the consistency was a little soft. Turns out, growing animal cells is one thing; but reproducing the structure of fats, collagen and blood vessels that give meat its texture is a big technological challenge. Scientists are still experimenting with scaffolds, as theyre called, to give the meat structure. And theres another challenge. T when you ssomebody, heres a piece of meat that was grown completely in a lab, somp might say, eh, im not so sure about that. How do you. How do you get beyond that . Nk i te should be realistic, and the industry should be realistic, that wexp just cantt everybody to say, yes, im behind it. Tes going to take time. Reporter deshe hurdles, memphis has attracted more tn 20 million of vestment from bigname backers like bill gates, Richard Branson and rge food giant l. Tyson foods, one of the biggest meat producers in the world, has a Minority Stake in the company. Executive Vice President amy tu oversees tysons venapital fund. Our focus is on ourna traditbusinesses, but we cant ignore the fact that the consumers are demanding different types of products. We want to be at the forefront of the future of food. So, in order to do that, we may be looking at areas that may have been uncomfsttable in the reporter memphis meats is not the only company now trying to make cellbased meat a commerci reality. In just the last few years, several startups have launched in the u. S. And around the world. The interest is spurred, in part, by growing concerns abouta sustainabilimeat production requires more resources than other foods. About onequarter of the worlds icefree land is used for livestock grazing; about a third of our cropland is used to grow livestock feed. And, according to the u. N. , livestock production contributes almost 15 of the worlds greenhouse gases, about the same as transportion. More people will eat meat tomorrow than they are today,it an a big issue. Reporter josh tetrick is the c. E. O. Of San Franciscobased, food compast, inc. S e Company Began launching vegan food produ 2013. Its novel items, like eggless eggs made from mung beans, are available across the u. S. Just, inc. , is now trying its hand at cellbased meat. If there are so many issues with eating meat, tn why continue to promote it . People like eating meat, you know. Its just the way it is. If we can figure out a way toem allow o eat all the meat they want, just a different kind of better meat without all the issues, i just think thats the most pragmatic way to fix the problem. So, this is our Early Research lab for our cultured meat project. Reporter biomedical engineer vitor santo is just, inc. s director of whats known as cellular agriculture. He explained, the process starts with a small biopsy of an animal. It can be from a tiny piece of tissue, a small blood collection. Reporter and the athen walks away. Exactly. So, in this container, whave some of our chicken cells. Reporter the chicken cells feed on a cocktail of proteins, sugars and vitamins. The process also requires a substance to spur cell growth, often made from the blood of fetal cows. Obtaining this Fetal Bovine Serum is a huge obstacle to scaling up production. Its usually used in medical research, and its expensive and controversial. It comes from slaughtered pregnant cows which means, for now, some of the cellbased meats made by just, inc. And other companies arent actually slaughterfree. Just, inc. Is working to create a new, plantbased alternative. Fe really want to get rid it for ethical reasons and also because its very expensive. Eporter using the curre process, it takes santo about two weeks to pduce this. So, this is our ground chicken meat, freshly harvested from the tank, the bioreactor where we are growing it. Reporter the meat is used in just, inc. s crispy icken nugget. Another challenge here is the pric this nugget cost about 100 to produce. Try it youve got to try it. Reporter but c. E. O. Josh tetrick says the price is falling quickly and that hell be ready to launch his Chicken Nugget soon. The issue now is that it hnt been approved by the government. The u. S. Food and Drug Administration and the department of agriculture have agreed to jointly oversee cellbased meats. Wa and w to be true World Leaders on this topic, as we have a challenge to feed the world. Reporter but the government has not yet decided how it will approve the products, inspect facilities, or what the rules will be for package labeli. And cellbased Meat Companies arent the only ones concerned with that. E w not against technology whatsoever. We want them just to play by the same rules. Eporter cattle rancher kevin kester says he wants to see the same government inspections of cellbased meat labs that traditional meat facilities get. And he wants it made clear on labels that the meat came from a lab, not from a ranch. We want a level and fair Playing Field to wheabeling claims and marketing claims are accurate and it doesnt confuse the consumers. Reporter kester is a fifth generation rancher raising more than 2,000 head of cattle on abo 22,000 Rolling Acres in central california. Kesters alsserved as president of the National Cattlemens beef association. He bristles at thenvironmental claims that supporters of cell based meats make about the beef industry a lot of people say, you know, its really resourceintensive it uses a lot of water and a lot of land. What do you say . A huge amount of that land is not viable for any other production. Reporter le the land on his ranch, which is steep and rocky. So, the highest and best use is for cattle. Reporter according to the u. S. D. A. , American Cattle production only contributes about 3 of u. S. Greenhouse gas emissions. And kester says the industry is improvg sustainability and efficiency through better breeding and feeds. With less cattle, i can produce 33 additional pounds of beef because weve improved through technology and genetics what we. What it takes toof produce a pouneef. Reporter do you think that theyll ever be able to grow aur har like this in a lab . I think, given enough time and research and development, yes. I do. Reporter and youre okay with that. I can. Sure. Itll be a long mame before the rity of at least the population of the u. S. Would want to eat a labgrown product. Reporter even so, some experts say we need to starter getting annow to questions about the safety of these new products. This is a very disruptive technology, and what are the ticipated risks . We should be thinking about those now rather than being reactive later on and trying to. Respond to t reporter Barbara Kowalcyk is a food safety expe at Ohio State University and sits on the f. D. A. s science board. Kowalcyks not opposed to cell based meat but says there are a lot of questions the government needs to get answered before it approves the meat for market. Kowalcyk says we cant rule out the possibility of foodborne illness, and she wonders about the longterm Health Effects ofu the substancd to make the meat. And those might be chronic Health Effects. So, they might not emerge until someones consumed it on a repeated basis. And so, it may be years before we would actually be able to see a health impact. U. Reporter the problem, she says, is that ths. Doesnt systematically track the Health Effects of new food productsr afeyre introduced. She thinks cellbased meats should be regulated as biologic drugs. Their approval requires a lot pmore upfront and follow research about their safety. We havent stepped back and said, before we embrace this, lets look at the unintended consequences. Reporter memphis meats c. E. O. Uma valeti acknowledges the concerns but points out conventional meat is one of the biggest sources illness, and its often contaminated during the slaughtering process. Because were detaching slaughter from meat production, we are dramatically reducing the chances of contamination happening, therefore making food safer. Reporter in the meantime, valetis charging ahead with his bold vision. G. Ltimately, this is comin this is inevitable. Reporter hes hoping to get thgreen light from the government soon. This is pbs newshour weekend, saturday. Sreenivasan in new york city, a modernday version of stonehenge is a delight for residents and visitors alike. Its aptly called manhattanhenge, and it lasts for just a few minutes if the weather cooperates, which this year it did. Thousands run out onto the busy streets of new york city to try and capture a rare and dazzling moment. It happens only four days a year, when the sunset aligns with manhattans street grid, turning the citys high rises into canyon walls with a sunsetl perfin the center. The goal for those out in the streets is that perfeco. Rs it is almost spiritual. Ive waited 20 yo see that, and it actually sets exactly in the middlof the street i didnt expect that, but it was. It was very, very nice. N sreenivasan more tha0 years ago, the architects whott designed manhas streets decided to use a grid system, with avenues running north and south, and streets east to west. As the earth tilts along its axis, the sun eventually is positioned in the Perfect Place for a sunset view on somof the citys widest street astrophysicist Neil Degrasse tyson came up with a name for what happens every year, similar to the annual solstice sighting at englands stonehenge. He dubbed it manhattanhenge. Since we learned about the phenomenon, since Neil Degrasse tyson named it, weve been following it. And so, weve been tto time trips to be here when it happens. Sreenivasan this yt rs view did sappoint. We were here three years ago, and didnt get a successful sunset. It was just cloudy right at the. Right at the last moment. But tonight, it was pretty good. Sreenivasan the next manhattanhenge wont occur until the spring of 2020, weather permitting. Sreenivasan finally tonight, for the First Time Since 1965, ypt opened two of its oldest pyramids to visitors today. The two pyramids are parof a World Heritage site about 25 miles south of cairo.
