It was 62 years ago this week thathe Supreme Court outlawed segregation in public schools. But it never went away. A study ordered by Congress Found the percentage of highpoverty schools with mostly black or hispanic students has more than doubled since 2000. Michelle miller went to a district in the deep south thats been ordered to desegregate. Reporter the mississippi delta town of cleveland has been grappling with its segregated past for 50 years, and now its time has run out. In a ruling, a federal judge ordered the district to merge two high schools and two middle schools, saying the delay in desegregation has deprived generations of students of the constitutionally guaranteed education. Jamie jacks, the School Districts attorney, says the order doesnt give the full picture. We have kids learning side by side each other of different races. If you travel to our surrounding communities here, youll see that doesnt exist. But we have it here. Reporter the problem centers around clevelands two high schools. Cleveland high is an historically whitesonly school and is now evenly split. But east side high still has a student body that is virtually 100 africanamerican. Students we spoke to fear the impending change. Its this side of the highway versus that side of the highway. Its been a rival for a long time. Reporter margaret schwartzbakers kids go to cleveland high. Reverend edwin duvals to east side. I think the white are afraid to become a minority and lose control. But i think its to move forward i think as one unified school where everybody can accelerate. Reporter School Desegregation protests across the country are part of an ugly past. And the fight continues in the courts. There are currently 177 active School Desegregation cases. Half in mississippi and alabama alone. Deputy assistant attorney general vinta gupta heads the civil rights division. I do think its jarring to people to know that in fact still many of our schools remain segregated and that that is something we need to change. Reporter here the debate is how to make the change.

She was with this man, identified as her husband and a boko haram soldier. The girls were violently snatched from their school two years ago. Since then the Nigerian Government has been unable to free the girls or even find them. The kidnapping sparked global outrage and a campaign called bring back our girls. Which only intensified when the Extremist Group released video claiming to show its christian victims converting to islam. But despite the worldwide attention, the trail went cold until last month when a new video surfaced, appearing to show at girls were still alive.

Why do some patients with colon cancer survive longer than others . Heres dr. John laok glassco had surgery for what was thought to be an earlystage colon cancer. It had actually spread across my body. So at that point they staged it stage 4 colon cancer, not in the terminal sense but in the fact that it had moved. Reporter she had six months of chemotherapy, but earlier this year the cancer returned, prompting another round. Todays the halfway through mark. The side effects are hitting me a little bit harder than they did last year. Reporter her cancer had started on the right side of the colon, a location that can be more deadly. Todays study of patients with advanced colon cancer found those with tumors on the right side survived an average of 19 months compared to 33 months for those with tumors on the left side. Dr. Richard goldberg is an oncologist with the Ohio State University comprehensive Cancer Center and is a coauthor of the study. This data shows that we ought to be thinking differently about patients depending on where their cancer arose. Reporter patients with cancer on the right side tend to have fewer early symptoms are often diagnosed later. One reason benign rightsided polyps can be harder to spot during a colonoscopy. Many polyps are obvious, like this one that looks like a mushroom. But polyps on the right side tend to be flat, increasing the odds of being missed and eventually turning into cancer. When i go to clinic next time, im going to be thinking, right side, left side. Different treatment. Reporter todays study suggested certain types of chemotherapy may be more effective with colon cancer starting on the right side than the left. That may be especially relevant for africanamericans who are more likely than whites to have rightsided colon cancer and less likely to survive. Thanks, jon.

Id like to buy the world a home and furnish it with love reporter the ad for cocacola hit the airwaves in 1971, and it wasnt long before the world was singing it.

Grow apple trees and honeybees and thats the overnight news for this thursday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im anthony mason. Announcer this is the cbs overnight news. Welcome to the overnight news. While the Republican Party is slowly coming together behind the presumptive president ial nominee donald trump the democrats continue to battle amongst themselves. Hillary clinton and Bernie Sanders split the primaries tuesday. Sanders winning oregon. Clinton taking kentucky by less than a point. Their fight for delegates is becoming dirty. Nancy cordes reports. Reporter this is striking because the party has been treating sanders with kid gloves lately, wary of alienating his millions of supporters. But those gloves have come off after an ugly incident in nevada. They say his campaign could have prevented. And theyre worried there could be more to come. I am getting to like the coast [ cheers and applause ] reporter as sanders reveled in his oregon win, the clinton camp celebrate aid photo finish in kentucky, enough to halt a sanders winning streak. Thanks to everyone who turned out, clinton tweeted. We are always stronger united. But that unity is being tested by a growing dispute over nevadas chaotic Democratic Convention. It was disrupted for hours this weekend by sanders supporters who were angry about the delegate rules which they felt favored clinton. In a blistering letter monday state Party Officials accused the Sanders Campaign of inciting disruption and, yes, violence by an irrational minority. They started rushing the stage. Reporter roberta lang is the state party chair. They stood in front of me and were yelling vile things at me, calling me names. We had chairs thrown at the stage. Reporter and the abuse didnt end there. Officials say sanders supporters posted her cell phone and home address online. Shes gotten hundreds of i would pack your bags right now because the [ bleep ] storm youve ensued is coming. Reporter on tuesday the senates democratic leader who represents nevada says sanders needs to vocally condemn those tactics. Im hopeful and very confident senator sanders will dot right thing. Reporter but a defiant sanders faulted nevadas Party Leadership saying it used its power to prevent a fair and transparent process. Officials quickly called that a lie. I say to the leadership of the democratic party, open the doors, let the people in reporter the chair of the Democratic NationalCommittee Said last night sanders is adding fuel to the fire when he could be putting the fire out. Very rare to hear her criticize one of her candidates. He picked up just four more delegates than clinton, who now leads him by about 3 million votes. For the republicans donald thump continues to march through essentially unopposed. Trump needs fewer than 80 delegates to clinch the nomination. Polls show hes not doing well with woman voters. But one powerful woman is standing up for him. His daughter, ivanka. She sat down with norah odonnell. Im going to ask you about the new york times. They ran a frontpage article this sunday about your father and the treatment of women. Did you read it . I did. And i found it to be pretty disturbing based on the facts as i know them. And obviously i very much know them, both in the capacity as a daughter and in the capacity as an executive whos worked alongside of him at this company for over a decade. So i was bothered by it. But its largely been discredited since. Most of the time when stories are inaccurate theyre not discredited. And i will be frustrated by that. But in this case i think they went so far, they had such a torong thesis and created facts and i think that narrative has been playing out now, and theres backlash in that regard. I do want to read you from part of the article. It says many of the women interviewed revealed unwelcome romantic advances, unending commentary on the female form, a shrewd reliance on ambitious women and unsettling workplace conduct. Is there unending commentary on the female form . No. No. And again, this is an article that is widely being discredited. The lead person who was interviewed for the story and that the story opens up with is all over the news yesterday saying that they manipulated what she was saying. I dont find it that meaningful to comment on this particular story because i think the facts are starting to speak for themselves. But you have worked so closely with your dad. Theres another woman who is quoted in the article that says that donald trump groped her at a you know, at a meeting, at a business meeting. Look, im not in every interactn but hes not a groper. Its not who he is. And ive known my father obviously my whole life. And he has total respect for women. He was promoting women in development and construction at a time when it was unheard of. There was no trend toward equality in the real estate and Construction Industry back in the 1980s. And he was doing it because he believes ultimately in merit. Hes running against a woman. And he has said that hes already using gender as a way to run against her. Well, is he using gender or is she using gender . I think shes using gender as well. Im not going to advocate for a female leader who im voting for solely on the basis of gender. The people who run Yellowstone Park are coming under fire for their decision to destroy a baby bison. A park visitor put the bison in the back of his suv, and that started a chain of events that led to the babys death. Mark s reporter every visitor driving into yellowstone gets a map, a park newspaper, and these safety guidelines against getting too close to wildlife. Well, someone apparently forgot to read these. With bison park visitors are told to stay at least 25 yards away. Mature bulls can weigh more than a ton and stand six feet tall. But a 69yearold canadian tourist thought this bison calf looked cold and apparently abandoned, picked it up and turned it over to park rangers. Once they have the smell of the humans on that calf, you certainly raise the risk that they will not be able to be successfully reunited with their parent. Reporter dan wanck is the part support. He told us bison herds later rejected the calf and it began to approach people and cars and become a traffic hazard. Ultimately that resulted in the destruction of that calf. Reporter you described it as misplaced concern. Is that the nice way of it is a nice way of describing it. They were wrong. Reporter yellow stone is not a petting zoo. This video shows a bison flipping a man who got too close. Another video shows a bison charging a boy who crept within feet of it. Bison gored five visitors last year. A grizzly killed another visitor. But yellowstone has a pr challenge with the killing of the bison calf, which they defend as necessary but has churned outrage on social media. Yellowstone explained that in order to ship the calf out of the park it would have had to go through months of quarantine. In the end a visitors illadvised rescue attempt became a death sentence for the calf. A reminder to all visitors to respect wildlife space. Yellowstone National Park is their home. They understand how to live and to succeed and to thrive in this environment. Reporter the canadian tourist was given a citation for getting too close to but park Officials Say their investigation is continuing and more charges are pending.

It uses the polio virus to fight a vicious form of brain cancer. Well, the results are promising. And the federal government has granted the treatment breakthrough status. That means this new dramatic way of fighting cancer will become more available across the country. Heres scott pelley. Reporter Nancy Justice had been sentenced to a bleak prognosis when we met her in october 2014. At age 58 she had recurrent glio blastoma. It had come back after surgery, radiation, and chemotherapy. Typically, she could expect to live seven months. The polio virus which mankind had fought earth was the last chance she had in the world. Just a tiny tug there. Reporter a half teaspoon of pollio flowed through a catheter inserted through nancys skull directly into her tumor. Okay. Read yy to go. Im ready. Bring it on. Were starting. 9 21.

Reporter her glioblastoma was diagnosed in the 21st year of nancy and gregs marriage, just as the georgia couple could make out the finish line for zack and luke at college. Her tumor can double in size every two weeks. The tumor was aggressive. So you wanted an aggressive treatment. Yes. Yes. Youre a medical explorer. Does it feel that way to you . Im taking it one day a time. It sounds very lofty to say medical explorer. But you know, throughout all of this if this gives other people hope im all for it. Greg, you mentioned that nancy was there for every important event in the boys lives, but there are a lot of important events to come. Exactly. What do you hope to see . So i am going to see those boys walk across the stage at their college graduation. I am going to see them get married. And i am going to see grandkids. Preferably in that order. And i know its like such a mom bucket list. But ill love every minute of it. The number of calls are increasing again. Reporter this is dukes polio team. Dr. Darryl bigner, director of the tisch brain tumor center. Molecular biologist andreas gromeyer and neurobiologist Henry Friedman and Monique Desjardins. As is typical, theni Research Dollars to the therapy. And all the members of the team are investors. Good to see this is going well. Reporter dr. Friedman screens more than 1,000 glioblastoma patients a year who would like to be treated at duke. He helps decide who meets the criteria for the polio trial. I wonder, of all the trials and all of the theories and all of the treatments that you have hoped for all of these years, how does this stack up . This to me is the most promising therapy ive seen in my career. Period. Reporter the virus is the creation of t, the obsession of dr. Gromeier who has been laboring over this the last 25 years. The last 15 at duke. When you went to your colleagues and said ive got it, well use the polio virus to kill cancer, what did they say . Well, i had a range of responses from lying to all kinds of things. Most of them thought it was just too dangerous. I thought he was nuts. I mean, i really thought that what hes using is a weapon that produces paralysis. Reporter other researchers are experimenting with cancer treatments using viruses including hiv, smallpox, and measles. But polio was dr. Gromeiers choice because as luck would have it it seeks out and attached to a receptor that is found on the surface of the cells that make up nearly every kind of solid tumor. Its almost as if polio had evolved for the purpose. Here is the genetic material reporter gromeier reengineered the virus removing a key genetic sequence. The virus cant survive this way. So he repaired the damage with a harmless bit of cold virus. This new modified polio virus cant cause paralysis or death because it cant normal cells. But in cancer cells it does. And in the process of replicating it releases toxins that poison the cell. At least thats what theyd observed in the laboratory. Eventu eventual eventually they had to try it in a human being. Its a hell of a thing to be told you have months to live when youre 20 years old. In 2011 Stephanie Lipscomb was a Nursing Student with headaches. A doctor told her she had this glioblastoma tumor the size of a tennis ball. I looked at the nurse that was sitting there holding my hand, and i said, i dont understand. What did he just say . It was kind of hard for me to process. You had 98 of the tumor removed. Exactly. As much radiation as you can have in a lifetime. And chemotherapy. Exactly. And then in 2012 what did the doctors tell you . Your reporter with Recurrent Glioblastoma there were no options. Except the one that had never been tried. Did they tell you that it had never been tried in a human being before . They did. But at the same time i had nothing to lose honestly. Reporter her polio treatment began in 2012. And from the very beginning it looked like a bad bet. So we treated her in the may. Then in july the tumor looked bigger, looked really inflamed. I got really concerned, got really worried. You thought this wasnt working. I thought it wasnt working. Neurooncologist Monique Desjardins wanted to abandon the polio experiment and return to traditional treatment, but stephanie said no. Five months after her infusion an mri showed the tumor only looked worse because of inflammation caused by stephanies immune system, which the first time and gone to war. Why didnt the immune system react to the cancer to begin with . Cancers, they develop a shield or shroud of protective measures that make them invisible to the immune system. And this is precisely what we tried to reverse with our virus. So by infecting the tumor we are actually removing this protective shield and telling enabling the immune system to come in and attack. So essentially whats happening here inside the tumor is you have a polio infection. Yes. And that sets off an alarm for the immune system. Yes. The immune system says theres a polio infection, wed better go kill it. Exactly. And it turns out its the tumor. Yes. Reporter it appears the polio starts the killing but the immune system does most of the dama months until it was gone. Three years after the infusion something unimaginable had happened. This is from an mri in august 2014. And theres no cancer in this picture at all. We dont see any cancer, active cancer cells. Reporter she is cancerfree.

Video game companies, media giants, and Hollywood Studios are all putting out content. And affordable goggles are now on the market. Its driving vr into the mainstream. John blackstone paid a visit to Stanford University, ground zero of the vr revolution. Reporter inside this small office at Stanford University professor Jeremy Bailenson has the ability to make your wildest dreams a reality. You can grow a third arm. You can travel the world. You can go to the bottom of the ocean. And the possibility to do things that we could only imagine previously is really neat. Reporter its called the virtual Human Interaction lab, and its become a mustsee for Silicon Valley titans. Like facebooks Mark Zuckerberg, looking to get into the booming Virtual Reality market.

Wow. Okay. Reporter the chasm looks so real my knees are shaking. I know the floor is solid. But part of my brain is shouting dont do it. Take a step off. Hard to do. But ah good job. Good job. Virtual reality is not a media experience. When its done well, its an actual experience. So the impact of doing something with these goggles on is greater than the impact of looking at the same thing on a flat screen on my smartphone . In general our change, causes more engagement, causes more influence than other types of traditional media. Reporter over the next 30 minutes i virtually learn new skills. Wow, that one hurt. Reporter like blocking hockey pucks. And training my body to react quickly during an earthquake. Wow. This is pretty real. Reporter but the teaching can also go much deeper. I want you to bend down at the knees so you cant see yourself anymore. Go all the way down, all the way down. Now come up. Oh. Oh. Thats the reaction were after. You are now a woman of color. Reporter i am suddenly transformed, appearing to have changed both my gender and race. Bailensons research has shown this exercise in empathy can actually change the way people act toward others. Becoming someone else in Virtual Reality and experiencing this firsthand in general cause a reduction in prejudice compared to the typical way we try to address this, for example, role playing or mental imagery. Reporter risks. Virtual reality is potentially more addictive than video games and smartphones. Virtual reality is consuming. You put it on, youre there. Its really intense. And you actually feel like youre there. Reporter so intense that vr goggles are not recommended for children under 13. And users are encouraged to take breaks every 30 minutes. Its a powerful tool. That power of the experience doesnt come for free. Is this too powerful for people to have freely . In the wrong hands technology can be good and it can be bad. Uranium can heat homes and it can destroy nations. And Virtual Reality is a medium. Its up to us to use it for good. Reporter bailenson has been studying Virtual Reality since 1999. This year he is finally seeing it enter the consumer mainstream. Its a pretty special time to be doing Virtual Reality. Its not virtually real. Its real. Its real. Whoa. Whoa. Okay.

Reporter this thing is as tall as a 15story building. So moving it around is not an easy task. And the journey to get here, well, its been quite the trip. And liftoff. Reporter every Space Shuttle mission was propelled by a massive workhorse, a 66,000pound fuel tank that blasted the shuttle into orbit. And separation from the external tank. Reporter it would then break off and disintegrate. But when the Shuttle Program ended, a single fuel tank remained, never having flown. The surviving shuttles all went to endeavour is now parked at the California Science Center in l. A. Its an amazing machine. So we wanted to show the whole thing and help explain how challenging it is to go to orbit. Reporter its one thing to want a fuel tank. Its quite another to get it delivered. Et94, as its called, was housed at a nasa warehouse in new orleans. An 1,800mile drive to los angeles. This is a little too big to go on a road because its just too large to go under any bridges or overpasses. Reporter so instead the giant fuel tank was loaded onto a barge, sailing through the gulf of mexico and the Caribbean Sea through the panama canal, up the Pacific Coast by san diego, and now just outside of l. A. The sixweek, 5,000mile journey cost 3 million. Now just 16 miles remain. The tough jeest 16 miles. From the marina to the museum.

[ cheers and applause ] navigating space may have been easier than navigating l. A. Streets. The fuel tank will soon get a similar escort. But thats not the ultimate mission. Its really to stimulate the next generation of scientists, engineers and explorers. It really represents our hopes and our dreams of exploring the unknown. Reporter now, eventually this fuel tank is going to be attached to the Space Shuttle at the science center. Theyre then going to rotate both of them 90 degrees so theyre sticking upright just like they did in the launchpad. The road trip for the fuel tank begins early saturday morning. And that of course is designed to make sure it does not get stuck in l. A. s notorious traffic. Thats the overnight news for this thursday. For some of you the news continues.

Reporter the mississippi delta town of cleveland has been grappling with its segregated past for 50 years, and now its time has run out. In a ruling, a federal judge ordered the district to merge two high schools and two middle schools, saying the delay in desegregation has deprived generations of students of the consti right of an integrated education.

Amina ali and her fourmonthold baby were found today near the Sambisa Forest where she was collecting firewood. She was with this man, identified as her husband and a boko haram soldier. The girls were violently snatched from their school two years ago. Since then the Nigerian Government has been unable to free the girls or even find them. The kidnapping sparked global outrage and a campaign called bring back our girls. Which only intensified when the Extremist Group released video claiming to show its christian victims converting to islam. But despite the worldwide attention, the trail went cold until last month when a new video surfacedpe show at least 15 of the chibok girls were still alive. For despairing parents it rekindled hopes of seeing their daughters again. Alis survival will only fuel those hopes.

A study out today helps answer a question that has troubled oncologists. Why do some patients with colon cancer survive longer than others . Heres dr. Jon lapook. Reporter two years ago at age 48 lisa glassco had surgery for what was thought to be earlystage colon cancer. It had actually spread across my body. So at that point they staged it stage 4 colon cancer, not in the terminal sense but in the fact that it had moved. Reporter she had six months of chemotherapy, but earlier this year the cancer returned, prompting another round. Todays the halfway through mark. The side effects are hitting me a little bit harder than they did last year. Reporter her cancer had started on the right side of the colon, a location that can be more deadly. Todays study of patients with advanced colon cancer found those with tumors on the right side survived an average of 19 months compared to 33 months for those with tumors on the left side. Dr. Richard goldberg is an oncologist with the Ohio State University comprehensive Cancer Center and is a coauthor of the study. This data shows that we ought to be thinking differently about patients depending on where their cancer arose. Reporter patients with cancer on the right side tend to have fewer early symptoms and are often diagnosed later. One reason benign rightsided polyps can be harder to spot during a colonoscopy. Many polyps are obvious, like this one that looks like a mushroom. But polyps on the right side tend to be flat, increasing the odds of being missed and eventually turning into cancer. When i go to clinic next time, im going to be thinking, right side, left side. Different treatment. Reporter todays study suggested certain types of chemotherapy may be more effective with colon cancer starting on the right side than the left. That may be especially relevant for africanamericans who are more likely than whites to have rightsided colon cancer and less likely to survive. Thanks, jon.

Grow apple trees and honeybees and thats the overnight news for this thursday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im anthony mason. Announcer this is the cbs overnight news. Welcome to the overnight news. Im vladimir duthiers. While the Republican Party is slowly coming together behind the presumptive president ial nominee donald trump the democrats continue to battle amongst themselves. Hillary clinton and Bernie Sanders split the primaries tuesday. Sanders winning oregon and clinton taking kentucky by less than a point. Their fight for delegates is becoming dirty. Nancy cordes reports. Reporter this is striking because the party has been kind of treating sanders with kid gloves lately, wary of alienating his millions of supporters. But those gloves have come off after an ugly incident in nevada. They say his campaign could have prevented. And theyre worried there could be more to come. I am getting to like the west coast reporter as sanders reveled in his oregon win, the clinton camp celebrated a photo finish in kentucky, enough to halt a sanders winning streak. Thanks to everyone who turned out, clinton tweeted. We are always stronger united. But that unity is being tested by a growing dispute over nevadas chaotic Democratic Convention. It was disrupted for hours this weekend by sanders supporters who were angry about the delegate rules which they felt favored clinton. In a blistering letter monday state Party Officials accused the Sanders Campaign of inciting disruption and, yes, violence by an irrational minority. They started rushing the stage. Reporter roberta lang is the state party chair. They stood in front of me and were yelling vile things at me, calling me names. We had chairs thrown at the stage. Reporter and the abuse didnt end there. Officials say sanders supporters posted her cell phone and home address online. Shes gotten hundreds of thre i would pack your bags right now because the [ bleep ] storm youve ensued is coming. Reporter on tuesday the senates democratic leader who represents nevada says sanders needs to vocally condemn those tactics. Im hopeful and very confident senator sanders will do the right thing. Reporter but a defiant sanders faulted nevadas Party Leadership saying it used its power to prevent a fair and transparent process. Officials quickly called that a lie. I say to the leadership of the democratic party, open the doors, let the people in reporter the chair of the Democratic NationalCommittee Said last night sanders is adding fuel to the fire when he could be putting the fire out. Very rare to hear her criticize one of her candidates. He picked up just four more delegates than clinton, who now leads him by about 3 million votes. For the republicans donald trump continues toar the primaries, running essentially unopposed. Trump needs fewer than 80 delegates to clinch the nomination. Polls show hes not doing well with women voters. But one powerful woman is standing up for him. His daughter, ivanka. She sat down with norah odonnell. Im going to ask you about the new york times. They ran a frontpage article this sunday about your father and the treatment of women. Did you read it . I did. And i found it to be pretty disturbing based on the facts as i know them. And obviously i very much know them, both in the capacity as a daughter and in the capacity as an executive whos worked alongside of him at this company for over a decade. So i was bothered by it. But its largely been discredited since. Most of the time when stories are inaccurate theyre not discredited. And i will be frustrated by that. But in this case i think they went so far, they had such a strong thesis and created facts to reinforce it. Been playing out now, and theres backlash in that regard. I do want to read you from part of the article. It says many of the women interviewed revealed unwelcome romantic advances, unending commentary on the female form, a shrewd reliance on ambitious women and unsettling workplace conduct. Is there unending commentary on the female form . No. No. And again, this is an article that is widely being discredited. The lead person who was interviewed for the story and that the story opens up with is all over the news yesterday saying that they manipulated what she was saying. I dont find it that meaningful to comment on this particular story because i think the facts are starting to speak for themselves. But you have worked so closely with your dad. Theres another woman who is quoted in the article that says that donald trump groped her at a you know, at a meeting, at a business meeting. Yeah. Well look, im not in eve but hes not a groper. Its not who he is. And ive known my father obviously my whole life. And he has total respect for women. He was promoting women in development and construction at a time when it was unheard of. There was no trend toward equality in the real estate and Construction Industry back in the 1980s. And he was doing it because he believes ultimately in merit. Hes running against a woman. And he has said that hes already using gender as a way to run against her. Well, is he using gender or is she using gender . I think shes using gender as well. Im not going to advocate for a female leader who im voting for solely on the basis of gender. The people who run Yellowstone Park are coming under fire for their decision to destroy a baby bison. A park visitor put the bison in the back of his suv, and that led to the babys death. Mark strassmann has the story. Reporter every visitor driving into yellowstone gets a map, a park newspaper, and these safety guidelines against getting too close to wildlife. Well, someone apparently forgot to read these. With bison park visitors are told to stay at least 25 yards away. Mature bulls can weigh more than a ton and stand six feet tall. But a 69yearold canadian tourist thought this bison calf looked cold and apparently abandoned, picked it up and turned it over to park rangers. Once they have the smell of the humans on that calf, you certainly raise the risk that they will not be able to be successfully reunited with their parent. Reporter dan wanck is the part support. He told us bison herds later rejected the calf and it began become a traffic hazard. Ultimately that resulted in the destruction of that calf. Reporter you described it as misplaced concern. Is that the nice way of describing it . It is a nice way of describing it. They were wrong. Reporter yellowstone is not a petting zoo. This video shows a bison flipping a man who got too close. Another video shows a bison charging a boy who crept within feet of it. Bison gored five visitors last year. A grizzly killed another visitor. But yellowstone has a pr challenge with the killing of the bison calf, which they defend as necessary but has churned outrage on social media. Yellowstone explained that in order to ship the calf out of the park it would have had to go through months of quarantine. In the end a visitors illadvised rescue attempt became a death sentence for the calf. A reminder to all visitors to respect wildlife space. Yellowstone National Park is their home. They understand how to live and to succeed and to thrive in this environment. Reporter the canadian tourist was given a citation for getting too close to wildlife and fined 110.

Reporter Nancy Justice had been sentenced to a bleak prognosis when we met her in october 2014. At age 58 she had Recurrent Glioblastoma. It had come back after surgery, radiation, and chemotherapy. Typically, she could expect to live seven months. The polio virus which mankind earth was the last chance she had in the world. Just a tiny tug there. Reporter a half teaspoon of pollio flowed through a catheter inserted through nancys skull directly into her tumor. Okay. Ready to go. Im ready. Bring it on. Were starting. 9 21. If you feel anything, you let us know. I will. Definitely. Reporter her husband, greg, constantly inflated a buoyant optimism to save him from the weight of the unknown. Okay. Reporter her glioblastoma was diagnosed in the 21st year of nancy and gregs marriage, just as the georgia couple could make out the finish line for zack and luke at college. Her tumor can double in size every two weeks. The tumor was aggressive. So you wanted an aggressive treatment. Yes. Yes. Youre a medical explorer. Does it feel that way to you . Im taking it one day at a time. It sounds very lofty to say medical explorer. But you know, throughout all of this if this gives other people hope im all for it. Greg, you mentioned that nancy was there for every important event in the boys lives, but there are a lot of important events to come. Exactly. What do you hope to see . So i am going to see those boys walk across the stage at their college graduation. I am going to see them get married. And i am going to see grandkids. Preferably in that order. And i know its like such a mom bucket list. But ill love every minute of it. The number of calls are increasing again. Reporter this is dukes polio team. Dr. Darryl bigner, director of the tisch brain tumor center. Molecular biologist andreas q gromeier and Monique Desjardins. As is typical, the university has licensed this technology to a new company to attract Research Dollars to the therapy. And all the members of the team are investors. Good to see this is going well. Reporter dr. Friedman screens more than 1,000 glioblastoma patients a year who would like to be treated at duke. He helps decide who meets the criteria for the polio trial. I wonder, of all the trials and all of the theories and all of the treatments that you have hoped for all of these years, how does this stack up . This to me is the most promising therapy ive seen in my career. Period. Reporter the virus is the creation of, the obsession of dr. Gromeier who has been laboring over this the last 25 years. The last 15 at duke. When you went to your colleagues and said ive got it, well use the polio virus to kill cancer, what did they say . Well, i had a range of responses from c t lying to all kinds of things. Most of them thought it was just too dangerous. I thought he was nuts. I mean, i really thought that what hes using is a weapon that produces paralysis. Reporter other researchers are experimenting with cancer treatments using viruses including hiv, smallpox, and measles. But polio was dr. Gromeiers choice because as luck would have it it seeks out and attaches to a receptor that is found on the surface of the cells that make up nearly every kind of solid tumor. Its almost as if polio had evolved for the purpose. Here is the genetic material reporter gromeier reengineered the virus removing a key genetic sequence. The virus cant survive this way. So he repaired the damage with a harmless bit of cold virus. This new modified polio virus cant cause paralysis or death because it cant reproduce in normal cells. But in cancer cells it does. And in the process of replicating it releases toxins that poison the cell. At least thats what theyd observed in the laboratory. Eventually they had to try it in a human being. Its a hell of a thing to be told you have months to live when youre 20 years old. In 2011 Stephanie Lipscomb was a Nursing Student with headaches. A doctor told her she had this glioblastoma tumor the size of a tennis ball. I looked at the nurse that was sitting there holding my hand, and i said, i dont understand. What did he just say . It was kind of hard for me to process. You had 98 of the tumor removed. Exactly. As much radiation as you can have in a lifetime. And chemotherapy. Exactly. And then in 2012 what did the doctors tell you . Your cancers back. Glioblastoma there were no options. Except the one that had never been tried. Did they tell you that it had never been tried in a human being before . They did. But at the same time i had nothing to lose honestly. Reporter her polio treatment began in 2012. And from the very beginning it looked like a bad bet. So we treated her in the may. Then in july the tumor looked bigger, looked really inflamed. I got really concerned, got really worried. You thought this wasnt i thought it wasnt working. Neurooncologist Monique Desjardins wanted to abandon the polio experiment and return to traditional treatment, but stephanie said no. Five months after her infusion an mri showed the tumor only looked worse because of inflammation caused by stephanies immune system, which had awakened to the cancer for the first time and gone to war. Why didnt the immune system react to the cancer to begin with . So cancers, all human cancers, they develop a shield or shroud of protective measures that make them invisible to the immune system. And this is precisely what we tried to reverse with our virus. So by infecting the tumor we are actually removing this protective shield and telling enabling the immune system to come in and attack. So essentially whats happening here inside the tumor is you have a polio infection. Yes. And that sets off an alarm for the immune system. Yes. The immune system says theres a polio infection, wed better go kill it. Exactly. And it turns out its the tumor. Yes. Reporter it appears the polio starts the killing but the immune system does most of the damage. Stephanies tumor shrank for 21 three years after the infusion something unimaginable had happened. This is from an mri in august 2014. And theres no cancer in this picture at all. We dont see any cancer, active cancer cells. Reporter she is cancerfree.
