the beaches of southwest gaza. more deliveries are expected in coming days from the u.s., egypt, and jordan. in the red sea, a ship has sunk, the first vessel to be destroyed by houthi attacks. it was carrying tons of fertilizer. yemeni officials call it an environmental disaster. fire and ice into states tonight. in the texas panhandle, they are battling the largest wildfire in the states history. since monday, the fire has killed at least two people and scorched 70 now hundred square miles of prairie and destroyed up to 500 structures. in the mountains of northern california and nevada, the biggest storm of the season has knocked out power to tens of thousands of homes. up to 10 feet of snow is forecast for higher elevations. donald trump won the missouri republican caucuses today.

the importance of bereavement care. ♪ >> this is pbs news weekend, from our studios in washington, home of the newshour, weeknights. >> crisis pregnancy centers provide counseling and other services from an anti-bird borscht -- antiabortion perspective. advocates of abortion rights say the information they provide can be misleading are have no scientific basis. there is a debate over trade for these facilities. >> they are nothing new. the first one opened in hawaii. these largely unregulated centers have seen renewed support and attention.

they brought in at least $1.4 billion in revenue. that includes 344 million dollars in government grants. there are an estimated 2500 such pregnancy centers around the country. about 800 clinics were operating before the supreme court overturned roe v. wade. thank you so much for joining us. tell us a little bit of how these centers work. what kinds of services to they provide? >> the point of a crisis pregnancy center is to convince people to continue their pregnancies. they offer certain services like pregnancy test. sometimes they do medical services like ultrasounds. they will also give out car seats or strollers.

many of these facilities are not actually licensed. >> when someone enters one of these centers, what kind of interactions are they likely to have? >> they can vary a lot. something that has come up again and again is people walk-in not necessarily knowing that they are not in an abortion clinic. these centers well often set up shop a very close to an abortion clinic. they will have names like the sort of things you hear from abortion-rights supporters. they are trying to convince you to continue a pregnancy. >> what kinds of people do they target?

>> they usually offer free services. i can usually be people who are low income. most people who get abortions are low income. it is so difficult for people to afford pregnancies in this country. >> why are they receiving more funding now? >> since the overturning of roe v. wade, the antiabortion movement has framed them as the place to go for women who might herwise have wanted an abortion but are now in a situation where they have little choice but to give birth. state governments, particularly in red states, have agreed with that logic. we know that 16 state governments have sent millions of dollars worth of taxpayer money to programs that support crisis he pregnancy centers. >> tell us more about the

breakdown of what we now know. about how they are getting their funding? where does the allocation come from? >> it can really be a mixture. some of the money that flows from the government to the states are from the federal government. >> there is now debate happening between the white house and congress over whether temporary assistance to needy families should be used for crisis centers. what is the status of those debates? >> it is a program that we would understand as being part of welfare. they can disperse these two families. one of the goals is to help

prevent out of wedlock pregnancies. the biden administratio has said by the time someone comes to iraq crisis pregnancy center, they already expect that they are pregnant. it is not the aim of a crisis pregnancy center to not have that occur. the biden administration introduced this rule. republicans in the u.s. house have had legislation that would block that rule. the bill did pass the house but given the state of congress right now, it is very unlikely that it will become law. >> likely something we will continue see in state houses. thank you so much. >> thank you for having me. ♪ >> the northern white rhino is

one of the biggest land mammals and one of the most endangered. only two are known to be alive, both female. but now there are hopes for saving the rhino and perhaps even bringing other animals back from extinction. when the last known male northern white rhino in existence died in 2018, iteems that the future of the entire species died with him. their population has been devastated by human activity, widespread coaching, and civil war's. today, only two females remain. both living in a conservancy in kenya. a recent scientific breakthrough has raised hopes for the animals survival. >> we aceved together something not believed to be possible. >> they successfully imprinted

an embryo into a surrogate mother. this was tricky. >> what we had to do was mimic nature. i never lost focus. >> now the team plans to use northern white rhino's perm that was harvested years ago. they are not able to carry pregnancies, which lasted about 16 months. the embryos will again be carried by southern white rhinos. th hope a calf can be born in the next couple of years. >> we want to save this social heritage.

we need a calf who can learn the language of the last two of their kind. behavior is something that needs to be constant. >> the northern white rhino who is conceived this way will not have the genetic diversity needed to sustain a healthy population. so theare working with a science company to use stem cells and jean editing technology to bridge the gap. >> if we want to reintroduce them to the wild, we have to tap into the variety of genes to fight against diseases. it should be a healthy genetic population.

it is a very pioneering concept. that gives us a lot of hope for critically endangered species. >> others scientists are trying to bring back the dodo bird. it becam extinct less than 80 years later because of deforestation, hunting, and destruction of nests by animals introduced by dutch settlers. she has spent 25 years studying the dodo. she is a biologist at the university of santa cruz. >> i became increasingly captivated by trying to figure out what it was about the dodo that made it so susceptible to coming extinct. also to learn more about this iconic species so we could bring more attention to the fact that people are causing extinctions day. >> she said the reintroduced

dodo will not be exactly the same as the birds before extinction. >> that is not the way evolution works anyway. if we think about this in a sustainable way, it cannot be this purest ideal. it has to be a creation of something new that is adapted for the habitat of today but could also potentially fill this void. >> in 2000, she took dna samples from the only known surviving soft tissue of a dodo, housed in a university. the closest living relative is a pigeon, found in parts of southeast asia. using another sample, they were able to announce that they had sequenced the entire genome >> >> of the dodo.

if we want to know what makes a dodo unique, we have to ha the entire genome sequence. then we can light it up with other birds. and look for the differences between the genomes. because of the intricacies of the reproductive system, one cannot clone birds. one of the biggest hurdles is to come up with some other way. >> the pigeon would provide the host cells and the genome for engineering. >> an important step because we cannot make millions of changes in a cell. we have to figure out which of those millions of differences are actually important to making a dodo look and act like a dodo. >> wire scientist making this effort to resurrect distinct animals? >> we are in the midst of an extinction crisis. we should be looking for all of

the different potential tools that might be out there to help species that are alive today and in danger of becoming extinct. these tools that we will develop on the path have immediate application to modifying the genomes of species alive today. potentially to help these organisms adapt. >> not because they were lost in evolution but because of us. because of human activity. we poached them down to extinction. we destroyed their habitat. science can provide a new alternative. we he to live in harmony with nature. we have to make responsible decisions about how to deploy resources. otherwise, there is no science that can save human civilization. >> tried to undo some of the harm of human activity.

♪ >> after experiencing her own personal tragedy, she founded a nonprofit organization that seeks to improve the policies and practices around bereavement care. tonight, she shares her brief but spectacular take on why every loss matters. >> our daughter was to me a very special person. when she was here, everyone wanted her to die quickly. hospice wanted her to die quickly. the funeral homes would say do you think she will die before she is one-year-old? if so, i will broker you a bettel or -- a better deal. the systems around us failed.

years later i discovered it was not myault. the systems were simply not there for families. ♪ after she died, i had this intuition that something else needed to exist for bereaved families. but i did not know what. i decided to quit my job and i started walking the sidewalks talking to people in washington about their life experiences. this is a nonprofit to make the world more livable for bereaved people. bereavement is systematic. most people do not realize that being exposed to bereavement is associated with other concerns and emergencies. teen pregnancy, dropping out of school, incarceration, suicide,

and premature death. there are stunning statistics around areas of concern that keep me up at night. one of those is that up to 90% of incarcerated youth experience a death event just prior to being incarceratd. we are incarcerating grieving children. if i go to capitol hill and say that, people will be stunned. mothers will say, where have you been? of course that is true. the first thing i would say to people is you are not alone. the person you lost matters. they mattered terrifically. for policymakers, this is not a republican or democratic issue. this is an issue that touches every person at some point in their life. there are many things i believe

we can do together to make the world a more livable place for bereaved people. this is my brief but spectacular take on why every loss matters. ♪ >> finally tonight, we would like to show you some of the 100 new species discovered underwater off the coast of chile. they were found using an underwater robot. researchers say it demonstrates how the chilean government ocean protections are bolstering biodiversity and providing a model for other countries. this looks like something dr. seuss may have created. it was found under 4500 feet of

water. is a squat lobster. just before this member of a rarely seen family of squid had his picture snapped, it squirted think, perhaps a reaction to seeing an alien-looking object beside it. among the other species found, glass sponges, deep-sea corals, and urchins. identifying them all could take years. with about 70% of the earth's surface covered by oceans and only a fraction of it having been explored, who knows how many more unknown and unusual creatures c be discovered, if their habitats can be preserved. on our youtube channel, we have a provided a detail of multiple storylines coming out of the israeli-hamas war. that is it for this saturday.
