hour, thanks so much for joining us think i am thomas dre drayton in new york, "consider this" is coming up next. have a safe night. what he considers to be the hindrance to peace. much more straight ahead. >> the worst outbreak of ebola that we've ever recorded. >> the virus never -- now nigeria. >> i don't know if the information is in whether this drug is helpful. >> we have been chasing it for over a decade. >> autism is up. we don't know what it is. >> 5% of the children have had

their autism go away. >> political upheaval in cuba. >> their goal turned people into political activists and forced political change. >> it was not a covert program. >> we begin with a week that brought both optimism and disappointment in the ongoing israel-gaza conflicts. hamas fired rockets and the israeli resumed air strikes in response. the suffering in gaza continued, as many as a third of gaza's 1.8 million people have been importanced to flee their homes. on wednesday just as negotiations were resuming, we talked about divisions between hamas and other palestinian groups his hopes for an extension of the ceasefire and some of the biggest hurriedless hurdles. >> chief

negotiator for palestine liberation organization. you have been involved in the negotiations. this ceasefire is very similar to one proposed by egypt weeks ago. why is hamas accepting it now when it could have done so then and saved lives and injured? >> time is right now. that's all can i say. i really believe that israel's acceptance of the egyptian initiative in the early days was a tactical acceptance. it. as a matter of fact i was involved in nine attempts to achieve humanitarian ceasefires for 24 hours 12 hours, two days five days seven days. and well, now, both sides, both of us, accept the ceasefire, what we need now is to sustain the 72 hours. we're working now in order to extend the 72 hours beyond the 72 hours.

and the most important thick now is to extinguish the fire. >> are you hopeful that we'll be able to sustain and extend as i know you've said before and keep the ceasefire in place? >> yes, i am. i'm hopeful. and i think it's doable. what we need to do is in parallel, as i said, sustain the ceasefire. and at the same time, we're working on the extension. and the third track what we're calling upon the international community united states europe the arabs, japan whoever can is to have an aerial land and sea passages, bridges, in order to bring together the required humanitarian relief needed. gaza is with no electricity, no water supplies. no sewage system. 480,000 people, one-third of gaza's population are now

officially homeless. i was speaking to mr. robert serri this morning, the representative of the secretary-general ban ki-moon of the united nations, and the commissioner general of the united nations relief and work agencies, they are talking about a total humanitarian disaster in gaza. so these are the three things that we're working on now. and in parallel, sustainable the ceasefire, extending the ceasefire. and providing the humanitarian needs. and i appeal to all nations. those who can. we cannot wait to repair the generator, the electricity generator. we need a new one. we need a new one and this can be in place or should be in place within hours. the same thing in our hospitals in gaza. we have 10,000 wounded. 10,000. 10,000. that's an accurate number. mostly women and children. we're in very, very short

supplies of medical supplies of doctors of surgeons. anyone who can give us a hand this will be very, very appreciated, this difficult hours of us. >> it is a terrible situation and i know moving forward, we looked at some of the points that palestinians have proposed. in further negotiations, in egypt and in the past palestinian negotiators had accepted demilitarizing gaza two decades ago. in points from paper we saw parts of the palestinian position is decommissioning should be linked to the occupation and the independence of the state of palestine. what exactly do you hope to see happen, what are you proposing? >> well i think once we sustain the ceasefire, once iowa we extend the ceasefire once we deal with the -- once we extend the ceasefire and, the israeli machines and guns and f-15s and f-16s i think day after

this we are asking one simple question: do you want to rebuild gaza so another israeli prime minister can destroy it again in 2016 and another one in 2018? do we want to, the international community to call upon us now to go back to negotiations, and then once we are back in the negotiating table, where netanyahu and his government will go business as usual, dictation, incursions, occupations, to undermine the two state solution, no, sir, the status quo will not continue, the taught quo no more. the sustainability of the ceasefire, the extension of the ceasefire, the humanitarian needs of our people in gaza the question to the international community do we see an end to the israeli occupation, a ceiling came to my home town jericho in this house i was born

in when i was 12 years old. i'm 60 now. i have six grandchildren now. it's time for this israeli occupation to end. and if mr. netanyahu chooses to play games and to continue his public relations blame-game assignment counting on the american congress and the senate, and all these things to blame us, he will find himself responsible for the west bank, gaza and east jerusalem. that's the honest truth. the situation cannot continue anymore. either the international community will stand tall and bring an end to this israeli occupation and once we end the israeli occupation the west bank, jerusalem, we are fully committed to one authority one gun and the rule of law. but if mr. netanyahu wishes to continue his siege and closure, he is not a partner for peace and we are not going to continue

this business as usual anymore. we cannot take it anymore. we cannot afford to have 12,000 palestinians have been killed and wounded in the last 28 days. antonio, every hour on the hour of the last 28 days 17 palestinians were killed and wounded. you don't see us in the united states. you don't humanize us in the united states. an israeli soldier that said that he's missing then cameras are on his family his mother his father his brother an israeli soldier is hit and hospitalized his face his family his mother next to him. have you seen us, have the american media focused on us to see the human faces? a palestinian child aged between two months and two years was being killed every three hours in the last 28 days. these are war crimes that were committed and we cannot afford it anymore. we cannot afford 12,000 palestinian innocent. we cannot take it in our conscience that this business

continues and this israel goes with impunity. and then now we are seeking ways to join the icc, the international criminal court. what happened in gaza was war crimes and we will hold israel accountable for it. >> we have seen horrible and shown horrible pictures of the children who have died, the children who have suffered in gaza but you raised the participate for peace and you signed a deal with hamas, does not recognize the state of israel. after this will hamas keep governing, can it not will the palestinian authority have nor influence and be able to lead a gaza that can be a partner for peace and lead to a two-state solution? >> sir we have as you have in the united states as israel has, we are the palestinian government. the palestine liberation-o is the palestinian government.

26 political parties including hamas. we don't ask parties to recognize nations. as a matter of fact the coalition in israel not only they don't recognize the state of palestine they dock some of them like bennett like lieberman don't recognize the state of palestine. my name is si berakat, i'm a member of the plo committee. we have on the 67 lines, a dare a challenge an israeli member of this cabinet to stand and say we recognize the state of palestine to live in peace and security with israel on the 1967 lines. it is a party a faction. >> but it is a party that organs an important part of the palestinian territories. >> say no more we have a national 60s government now.

we're in charge and that's why that is was one of the reasons for this war waged against gaza because netanyahu's aim was to keep palestine, he knows very strategically that no palestinian state in gaza and no palestinian state without gaza so he waged his war to undermine our reconciliation our national consensus government to keep the split going because at the end of the day he doesn't want a palestinian state. benjamin netanyahu is not a two-stater and that's the truth and that's why he waged this war. so if, now, as i'm telling you, there's the government of palestine, the plo, fully recognizes the state of israel to exist on the 1967 lines. can we hear an israeli cabinet member or a prime minister stand tall and say to you and to the israeli people it is time to put an end to this occupation, it is time put an end to this conflict, it's time live and let

live and we recognize the palestinian right to exist on the 1967 lines, we are not going ohear it. >> dr. sy beracat, we thank you perspective. thank you. >> thank you. >> turning to the ebola situation. the emergency operations center had raised its response to the highest lest, dr. thomas freeden says ebola can stop but it's going to be extremely difficult. >> it requires meticulous amount of detail. if you leave a single ember it's like a forest fire. one health worker not protected one contact not traced. >> freeden said ebola spreading to the united states is

inevitable but outbreak is not going to be large. just returned from the region where he worked with local and international experts to identify cases and train workers in containment. great to have you with us. we now are seeing a spanish priest who is being treated in madrid after being transported there from liberia. how concerned are you that this is the beginning of a bigger outbreak? >> well we need to be very vigilant about cases showing up in the united states and other places around the world, even the developing cities and places where airplanes come into. because a person could come in on a plane, and not show symptoms, go out into the community and then develop the

full blown disease and pass it on to other people. so this is a scenario that could happen in the united states and we need to be aware of it. it won't be a major spread of the virus and the disease like is occurring in west africa. we'll rapidly get a ring around it but several cases could be a major event. >> could the outbreak be worse than several cases, there are reports of bodies dumped in the streets and people not going for treatment and the cdc says that the data that's coming out of the region is kind of fog of war situation. that's a direct quote. >> that's true. the cases that are recorded are the ones that are actually observed, either as laboratory confirmed case or a probable case . so you actually have to see the person and make the determination that that is one of those two categories. there are a lot of people in the

villages that never see an epidemiologist and don't get counted in the statistics. so you should just consider those the bare minimum cases and there are many, many more cases. >> there is news there in liberia that they have cordoned the area, a lot of people getting sick were the health care workers. you were involved in containment efforts and you have lost froandz ebola. it looks like in nigeria the cases there might be the american who got to the airport, the contamination was through the nurse. how do we get containment efforts? >> we need to do more. the things we need to focus on if not in this outbreak but the next one is developing vaccines so we can at least immunize our health care workers so they're not at risk. in the current outbreak we need to double down on the protective

equipment and make sure that everybody that is seeing patients or even potential patients is trained in the use of these personal protective gear. >> talking about the vaccines we had dr. anthony fauche of the nih saying that the vaccine will get a human test, something in the works. is that taken dwoiblg people who are not sick? -- quickly to people who are not sick? vaccines before adequate testing. >> many of the vaccine candidates very promising ones have shown that they can protect animals from this deadly virus. so we have a lot of candidates. five, six, seven candidates that are very promising in these animal studies. what needs to be done are studies to show that these vaccines are safe in people. that could actually be done fairly quickly.

a safety trial could, running it would only take a few weeks. it might take a few more weeks to analyze the data and the like but those tests could be done pretty quickly. then we have something in the u.s. called the animal rule and many of these vaccines have low already passed them. people could see them go into people pretty quickly. >> and what about the serum z map? how quickly can we ramp this up, apparently there are very few doses available, is that something that should be sent to africa to see if it will help? >> well, one of the big problems with making any drug is the scale-up. so we don't need just a few doses of this. we need many, many thousands of doses of a drug like that. so that's going otake some time to produce -- to take some:00 to produce.

one of the reasons why this drug was made in tobacco plants is because you can make large system. there are other systems that make you know large amounts of drugs but we need to get those medications into those systems and start ramping up so we can get some americans protected but also the africans too. >> professor appreciate you joining us. thanks. back. >> aljazeera america presents a break through television event borderland... >> are you tellin' me it's ok to just open the border, and let em' all run in? >> the teams live through the hardships that forced mira, omar and claudette into the desert. >> running away is not the answer... >> is a chance at a better life worth leaving loved ones behind? >> did omar get a chance to tell

you goodbye before he left? >> which side of the fence are you on? >> sometimes immigration is the only alternative people have. borderland only on al jazeera america

>> world war i started a hundred years ago this summer and while a third world unimaginable. there is no doubt the intensity of conflicts raging from

ukraine, china to the middle east, raise question where we're headed. former secretary of state madeline week. >> there are many issues but to put it mildly, the world is a mess. >> new york times columnist roger cohen , has a column in , you have covered foreign affairs for a long time. you looked back to what happened before world war i, you argued there was an optimism similar to when the cold war ended, you argued that the unimaginable could occur. hypothetical situations, like

russian and chinese expansionism, world war iii might not be so unimaginable. >> i'm not saying it's likely antonio, but we would be foolish to dismiss the possibility. in the runup to world war i there was a bit of prosperity in the world, collectiveness not like today but nobody thought a war could break out in which 16 million people would be killed and four empires would collapse. i think today, clearly, the way the world is interconnected, the growth of institutions, like the u.n, make it unlikely. but i have not seen in my lifetime a world that feels so fragile or so dangerous or a world in which the united states seems to have pulled back from things, in a way that calls into question pax americana, the u.s. guarantees on global security that have existed since 1945. >> lets look at a few things you bring up and one of the opinions

you raise is that if there were to -- if the bigger conflict were to break out it could happen accidentally, not just intentionally. >> yeah, i think these things generally do happen accidentally. we don't foresee what the trigger points could be. when a serbian nationalist killed arch duke ferdinand in 1918, no one could imagine that or the sequel. when i was dreaming up the scenarios for that atlantic magazine piece that you mentioned i considered the possibility that with russian troops massed on the ukrainian border, president putin saying he will defend russian speakers anywhere and the presence of a large russian speaking minority in say estonia part of nato you could imagine a scenario where conflict bruce in estonia and

america feels drawn in. i had not imagined that the separatists in eastern ukraine might shoot down a sifn airlines and that without restraint on both sides could have easily escalated. >> we have seen the first forcible change in european borders since 1945 in crimea, putin doesn't seem to be backing down. and your concern with russia, the narrative is that the west is trampling on russian dignity and humiliation can be a catalyst for war. >> i think that's right. antonio, i'm very much influenced by having covered the war in bosnia for two years and i think president putin today is doing what milosevic did 20 years ago. he's using historic injustice, russia is said to be encircled to be suffering to be being punished by the united states,

and western europe and he's let loose this wave of aggressive russian nationalism. and the thing is with nationalism of that kind i think is that once the genie is out of the bottle, it's very hard to contain it. maybe putin has been looking for an off ramp in the last couple of weeks but we see the nationalism he has unleashed in eastern ukraine is unstoppable. the forces since 1945 and the united states in essence does nothing when you've seen what's happened in eastern ukraine in essence nothing and when you have the president of the united states setting a red line as he did, president obama in syria and then in essence walking away from it, i think that says to the world that it's kind of nobody's world today. everybody can just sort things out as best they can. it's striking to me that in the ceasefire now in gaza,

essentially was after secretary of state kerry left the scene that you have egypt and israel working it out kind of between themselves. so i think that vacuum combined with the strong nationalism in the rising power of china and also in russia makes for quite a perilous and imussibl combustible situation. >> we have iran developing nuclear capabilities and you bring up syria and the red line that president obama put in place. you argue that nothing in your opinion is more dangerous than american weakness? >> i think so antonio. debated. there are those that would say that if that very limited attack on syria by the united states and france possibly other allies had carried out then who knows what would have happened. you're igniting another conflict scenario after two unwon wars in

afghanistan and iraq and that is the most dangerous thing you could have done. or you can argue that the most dangerous thing for world is when the united states makes commitments that it doesn't uphold. and when the senate -- signal is given that okay under the nato treaties or article 5 with japan the united states is bound to come to the defense of its allies, when you signal that treaty commitments are not as sacrosanct as they were, is that more dangerous than limited use of force? i'm in the second camp. i think in the end, that is more dangerous because it means it's open season. you can do what you like. >> it's a very thought-provoke being article in the atlantic. roger cohen really a pleasure to have you with us. thank you. >> thank you for having me antonio. >> this next story sounds more like get smart than james bond. the

associated press reported the association for international development sent united states agents undercover to cuba. using health and civic programs as cover. it didn't work. this is the second situation we've heard of in the past few months jack gillham, good to see you. so you decided it would be a good idea to hire young costa ricans and puerto rico puerto puerto ricans. to go in. how did it work? >> they had wanted to do a cuban twitter program, that is a presume tiff social media program using text messaging.

they wanted to take these young travelers as they called them from venezuela, peru , costa rica rica, to go in. >> they were tourists in some cases and humanitarian workers in others. >> they posed as tourists, under the radar, doing usia work in cuba is illegal. you said about goo get smart. the cone of silence, they had to use encrypted thumb drivers, they had to obfuscate the files they used. they had to speak in code, like i have a headache, which means the cubans were catching on to them. >> they were sent in to do clandestine work with visme vix no

visual virtually no cover. >> it happened around the time that usaid officials were privately e-mailing their contractors saying you should probably avoid sending people to cuba, we value your safety and by the way it is to nonamerican citizens not just americans. >> this was connected to the cuban twitter that u.s. aid created. and now the attorney general, u.s. aid's attorney general is investigating that program. one big debate were whether both

operations were covert, if they were covert, they would require congressional notification. the state department says now no no no, newspaper of this was covert? >> that's right. and i think there's a distinction here. the obama administration has turned around and said look none of these programs were covert, it shouldn't be a surprise, not secret, we have to work with these countries that are not exactly the most favorable to this work. but once we put the thesaurus aside, based on whether or not it was a secret, a cover that the hiv program that one of them called a perfect excuse. they tried hide their identities, they tried to to hide the way they got money, and in zunzuneo if we remember, they started up a front company, routed money through

cayman islands is this something they want to investigate further. >> makes information about its cuba programs available at foreignassistance.gov, the work isn't secret or covert nor is it under cover and it basically says it's all about empowering citizens in cuba so they argue the point about whether this is covert or not. but one important point in all of this is, what damage do these revelations do to u.s. humanitarian efforts in other countries because if they were posing in some of these cases as humanitarian workers it certainly raises questions about humanitarian efforts elsewhere. >> well some public health officials that we spoke with today had raised concerns about using these programs, using health programs in an hiv

prevention workshop as a cover for doing political activity. the reason for that is u.s. aid already has a struggle in trying to get the cooperation and assistance of a foreign government to do their work. the u.s. government meanwhile had just said that it stopped doing covert programs under the cia vaccine programs to do political work that is particularly a vaccination program in pakistan that helped look for osama bashar al-assad. so there is tension of u.s. governmental doing its secret clandestine mission and humanitarian work and i think in this case it might complicate these matters. >> jack pleasure to have you back on the show. thank. >> we'll be back with more of "consider this." >> weekday mornings on al jazeera america >> we do have breaking news this morning... >> start your day with in depth coverage from around the world. first hand reporting from across the country and real news keeping you up to date. the big stories of the day, from around the world... >> these people need

>> autism has been long considered a lifelong developmental disorder. something that can be managed but not cured. but exciting new research is giving hope to parents with tens of thousands of children diagnosed with autism every year. the research shows that in many cases one in 10 children can make a complete recovery. joining us in new york is liz felt, the president of owners speaks. thank you for being with us. >> thank you for having me. >> what should parents of kids with autism think?

>> we have known that this treatment is the most efficacious effective treatment for this, there is no known cause, no cures, especially if this treatment is started and continues intensively for years is efficacious. >> it does seem to work for some, doesn't work for others. do we know why? >> no, we don't know why. two kids can start with the same approach, but have different outcomes. the problems is the access to that kind of treatment. it can cost a family up to $60,000 a year out of pocket for the treatments we're talking about which is unaffordable. we have been fighting in every state to require insurance

companies to cover those treatments. >> how successful have your efforts been? >> we are in a very big battle right now in north carolina right now with blue cross blue shield and the insurance companies don't want to pay for this. but the fact is aba is evidence based and critically important to progress. >> could the problem here be that behavioral therapy work for some and not for other because the autism spectrum is so broad that there might be so many conditions and some may be more treatable than others? >> autism is complicated it is a spectrum. but there are other co-morbidities that come with it. a third of our population is nonverbal, sleep disorders are very common. underlying medical conditions or associated medical conditions that could be contributing to the progress with aba and other kinds of treatments. >> what do you think of the skeptics that feel that there

are some that need to grow out of their symptoms of autism are dhaidz were misdiagnosed. >> there are one in 68 children being diagnosed each year with autism. we know those numbers are real and we also know that treatment helps and you can talk to any public school teacher they can tell you which ones have had intensive therapy treatments and which ones haven't and they can also tell you how they're going to progress over the years. >> ari neiman who is president of the autism self advocacy organization, argues that autism is like being left handed. what do you say to him? >> parents who are in crisis, emotional distress, financial

distress, desperate for resources. they say one in 68 kids being diagnosed. these are parents and children who need help. many of whom have very disabling co-morbidities that come with their autism and some who don't. that's fine but the fact is we have 50,000 kids aging outs of school, services every year who need jobs who want to live independently who need life skills, that is 500,000 over the next ten years and we did a national strategy to address that. i tell you we just last week passed autism cares which is the federal legislation that funds autism, the primary vehicle. we had unanimous consent from the united states senate, that doesn't happen for anything. it shows you the prevalence is so high, the elected officials know i.t. and it's in their backyards and we need to do something about it.

>> how much do you think can be done at this point? because it does seem that as you set one of the big issues now is we focus so much on how many children are being born with it, how many kids are being diagnosed with it. so many are becoming adults. how do you help families, how do you help those kids? is that going to be a major part of what autism speaks is doing? >> it already is, between employment and housing and adult issues. the most exciting thing we're doing is whole genome sequencing. we are sequencing 10,000 gomes from the individuals living -- 10,000 genomes, there are subtypes of autism and understanding there are subtypes will allow us to ultimately give personalized or customized treatment with individuals with autism. so the spectrum again some individuals will need a lot more help than others so the research

is critically important. >> hopefully being able to see what you can find from that dna, the genome. >> to lead to the underpinnings. >> we had bob wright to talk about it when that project was launched. issues. >> it is very important. >> thank you. >> "consider this" will be right back. >> start with one issue education... gun control... the gap between rich and poor... job creation... climate change... tax policy... the economy... iran... healthcare... ad guests on all sides of the debate. >> this is a right we should all have... >> it's just the way it is... >> there's something seriously wrong... >> there's been acrimony... >> the conservative ideal... >> it's an urgent need... and a host willing to ask the tough questions >> how do you explain it to yourself? and you'll get... the inside story ray suarez hosts inside story weekdays at 5 eastern only on al jazeera america >> what i admire so much about al jazeera america is that it is solely committed to journalism.

>> you're not just giving the headlines, you're also not getting fluff. >> the gap between the rich and the poor is growing faster in san francisco. >> you're going to get something you're not going to get anywhere else, and you're going to get these in depth stories about real people. >> as an unsecured creditor could receive just cents on the dollar. >> chronic homelessness has always been a challenge here in new orleans. >> we recently did a story about a mother who was worried about the air her children were breathing. >> this is not standard household dust. >> florida is an amazing place to work as a journalist. >> the rocky mountain west is really an extraordinary part of this country. >> i worked in nashville for six years, i know the stories that are important to people there. overcrowding is such a big issue at this school. >> people in the outer islands of alaska picking up tsunami trash, really committed to what they are doing, and they have a lot more work to do. if you really want to tell peoples' stories, you've got to go talk to the people. >> real reporting. >> real news. >> this. >> this. >> this, is what we do. >> al jazeera america.

there's more to finical news than the ups and downs of the dow. for instance, can fracking

change what you pay for water each month? have you thought about how climate change can effect your grocery bill? could rare minerals in china effect your cell phone bill? or, how a hospital in texas could drive up your health care premium. i'll make the connections from the news to your money real. >> when middle aged men used to get a middle age crisis, they would stereo typically get a sports car. now they get a prescription for testosterone. the food and drug administration doesn't approve of them unless they're accompanied by certain medical conditions. and doctors aren't even sure what constitutes low t to begin with. addressing this industry and the country,

manopause, aging insecurity in the $2 billion testosterone industry. david von draley wrote the article and joins us from kansas city missouri. let's start with what low testosterone means and its consequences. it can be a real medical condition that affects quality of life for men as they age. >> yes, absolutely, there is a genuine condition, medical condition, hypogonaddism, a body not producing adequate amounts much testosterone that men need to feel healthy. there is a believe that testosterone revels peak in puberty, and gradual decrease in men's 50s, 60s and 70s. the natural consequence of aging

have created a kind of a gray area where some doctors are prescribing testosterone supplements as a treatment for basically the normal consequences of age. some -- of aging. some people who get these treatments the way they're pitched they will make you feet younger more able to exercise more able to add muscle mass bulk up stay forever young. >> and improved sexual activity among other things. >> among other things yes. >> there are a series of problems, first they're not even clear what levels constitute low ces toft erroneous. there's no -- testimony ton testosterone. >> that's right pnl one of the other gray areas, question marks is low testosterone a cause or an effect, you know if you are

overweight, it suppresses your testosterone levels. if you are depressed your testosterone levels go down. so if you are not exercising, not watching your diet, it's going to cause your mood to be worse, your testosterone levels go down. is this something that can be solved or addressed simply with a lifestyle change or simply a magic jell or medication. >> it isn't clear that a patient taking testosterone will necessarily improve. there are certain placebo studies that show very little between the two groups. so are people being duped here? >> well, duped is a strong word. it is a subject that is perfect for the classic placebo effect. a man comes into the doctor's office. he's a little overweight, he's not sleeping enough.

he doesn't exercise. says doc my mood's down i don't feel like i have energy. the doctor could say well go change your lifestyle. get on a diet. lose the extra weight. you'll feel better. or the doctor can say here, take this supplement and then you're going to want to exercise more. you're going to want to change your diet. and magically all these other things are going ohappen. so -- to happen. so is it the testosterone or sit the man suddenly feels like he should be doing all these healthy activities, which wn is producing the -- one is producing the good results in the waistline and the bedroom? it's hard to tell. >> it is clear it's become a massive industry. you quote some sources that say the industry will swell to $3.8 billion in just four years. testosterone doses shot up ten times

worldwide from 2000 to 2011. you describe these low t clinics have sprung up everywhere and half of the men get a low t diagnosis. the danger is there can be complications that accompany testosterone therapy. >> these are cases of the prescribing jump ing out in front ferl of the science. pocial heart attack risk, stroke risk, the fda recently required warnings of blood clots in the veins, clotting in the veins. and so while there are always conflicting studies, depending on who is producing the numbers, the fda is waking up to this.

they have announced that they're going to really dig into the science. they've called a summit meeting for experts on the area to meet next month in washington and try to figure out what they should do about this. >> it will be interesting to see what the science comments up with because as you -- comes up with because as you point out throughout the piece, there are so many ways that men are trying to are supplement their testosterone from health care stores to prescription of the actual drug. "time" magazine's story is manopause 'til in the august antiissue. thank you for being with us. >> my pleasure, thank you. >> we'll be back with more of "consider this."

derrick great to see you as always. comets have fascinated people since people have been around and now we can actually reach out and soon actually touch one of these. the pictures are amazing. they show all kinds of surface features including boulders that are supposedly the size of house he 500 foot cliffs and all sorts of craters. how are scientists reacting to what we're seeing? >> scientists are very excited about what's coming up with the visit of rosetta at this comet. the images they are seeing so far are so incredibly enticing. the resolution is great, they are really very excited about digging so the science of what's happening at this comet. >> how big is this comet compared to others? i know it's two miles by two and a half miles and here we are showing how it compares to the island of manhattan. it's about as wide as manhattan but not nearly as long.

>> it's not unusual in a size for a comet. comets can range in size and this is right in there for a standard size comet. what's unusual about this one is the nucleus has that unusual shape to it. it has the two lobes that are seemingly connected by that much narrower neck and scientists are much intrigued by how it is the nucleus can be formed like this. is it the two pieces separate glued together somehow, is it a larger piece that was somehow erode away, and they are much interested in finding out how it becomes to be that shape. >> getting there is an incredible feat. it took ten years, circling the sun ten times to reach this speed. was there error for mission like this? >> when i look at missions like this antonio, i think there is actually quite a huge margin for error.

what i mean by that is this is a relatively small space crack, maybe the size of a small truck. you're trying to aim this at an object two miles by two miles millions of miles out in space and you're trying to get the spacecraft there on a particular day. so in this case for the accuracy with which it arrived at the point right on target right on time there are so many possibilities of things that could go wrong. so to me this is a real testament to the genius and ingenuity of the engineers and the operators who built and operate this spacecraft to get it to the right place on time. now, if you wanted to wonder about what that high school and college math was worth here it is staring us in the face. >> incredible amount of calculations to make that happen. it's going to tighten the orbit and get closer around launch a vehicle to land on the comet's surface. they're taking their time because they are going to figure

out what's the best place to land. some have hypothesized what brought it to earth, water organic molecules that helped spawn life. do you think this comet will help us answer those questions? >> i think this probe is going to go a long way to providing additional data points . there are so many possibilities, so many comet candidates out in the solar system the number is enormous so it's possible that water could have come to this planet in such a way, scientists need more data points in order to fill out the picture better. this is the third comet ary missions

comet. there is a lot that's going to be gathered from this of significant information. >> quick question, the reason we are not seeing a tail is because it's not close enough to the sun yet? >> that's one of the great things that's going to happen with this particular mission. the spacecraft is going to sit down on the surface of the coming it and the oacialter is going to travel to the comet as it comes to parahelion its close approach to the sun and as it's traveling look with the comet on that close approach they'll be able to gather data on the way the comet outgases and other effects to the comet. first. >> it will be incredible to see those pictures when they start coming occupy derrick pitts, great to you have you. that's all for now, the conversation continues on aljazeera.com or our facebook or
