it is more evolutionary than revolutionary. it is thinner, lighter, faster, better battery and a nicer screen. the screen, i think, is the big story on the hardware front. now it's 5 inches. the trend is bigger. great for entertainment, consuminging media. messaging, reading e-books, watching video and playing games. the cameras, samsung made a big deal about it. outward facing camera and a video camera for chatting. the hardware is impressive. but the story is software. the software of the galaxy s4 is where most people will be excited. some of the highlights of what to expect with the new smartphone next month is the ability, for example, to tilt to scroll. imagine you are reading a long website. the phone is look at your eyes and knows you are reading a website. you can tilt the phone up and down to scroll through text which is convenient. there are sensors where you can hover your finger just above the

screen to access information. looking at a bunch of subject lines for e-mails. you don't want to open them. hover your finger and you get a preview of what the e-mail is about. there are smarter cameras. you can remove people in photos if they photobomb you. there is the s translator. you can speak a language and it repeats it in another language. maybe you're traveling. there are all these features built into the phone. there were dozens of them unveiled on thursday. >> very impressive stuff. thanks for bringing that to us. a real life horror movie for greyhound bus riders. 15 minutes into the trip from atlantic city to new york city you will not believe what started crawling around. not just one or two roaches but dozens. in fact, hundreds, thousands, they say. one eyewitness said they were crawling everywhere on the seats, windows, on the passengers themselves.

oh, my. the b problem got to bad the bus stopped and passengers got out and got on another bus for the rest of the ride. >> sat down, roaches started crawling on our clothes, falling out of the ceiling, everything. >> there were like a thousand roaches. when i say infested, i mean infe infested. >> the man had roaches on his coat. the lady had a roach on her hat. it was terrible. >> oh, boy. i bet there was a lot of screaming on the bus. a greyhound spokesman said the passengers received refunds and they have launched an investigation. that will do it for me. more cnn "newsroom" at the top of the hour. now keep it here for sanjay gupta, md. hey, there. thanks for joining us. the new pope once had a health scare. it cost him part of a lung. he's 76 years old. so what does that mean for him now? and prescription medications improve concentration.

a new warning drives home the point. only do it with medical supervision. and a father with a dilemma. his son was facing 60 years in prison. let's get started. first an update on a boy who's become a friend of mine named yusef. this week is ten years since the start of the war in iraq. it's a painful reminder for yusef and his family. part of my cnn reporting is to remind you that in wars families and children suffer. yusef is one of them. the story that led him to me began with cruelty. masked men came to his home, covered him with kerosene and set him on fire. it's hard to imagine anyone

would do that to a child of 5 years old. six years later his story isn't so much about the cruelty. it's about strength and resilience and the pursuit of happiness. >> this is our classroom. i sit in that seat over there. >> reporter: it is amazing to me what a typical american, 10-year-old kid yusef has become. >> the molecules move faster. >> reporter: this was yusef, just 5 years old. he was attacked by masked men in front of his home in baghdad. they poured gasoline on his face and set him on fire. what's the first thing you remember about all of that? >> i just, like, remember a doctor getting a sponge. >> reporter: in iraq? >> i think they scratched it on me or something. >> reporter: they were trying to

take off some of the burned skin. >> yeah. >> reporter: his parents were desperate to see their boy smile again. just months after the attack they came to the united states with a single suitcase. their living expenses and medical expenses, all of it was paid for by the kindness of strangers. we have followed their journey since 2007. yusef has had 19 operations, a total of 61 procedures to help correct the burn damage. if you were going to have more operations what would you want to have done? >> like over here. >> reporter: on your right ear? >> yeah. >> reporter: let's see. you want it more like your left ear? >> yeah. >> reporter: do you tell people what happened to him? >> i have to tell them when they ask. sometimes it bothers me when

they look and don't ask. >> reporter: it doesn't bother yusef. he's a happy kid. he's smart, confident. his parents say he never complains. he never asks about the scars on his face. >> i hope he's not going to ask even when he grows up. that's going to really bother me a lot. if he's going to come to e me and say, like, why my face is that? i don't know what i'm going to answer. >> this one, i can see there's one, two, three. >> reporter: his parents say all of this feels like a dream. have you had a hard time making friends at all? >> no. when a new kid, the next day we're just friends. >> reporter: is that right? >> yeah. >> reporter: is anybody mean to you? >> no. >> reporter: he's been at the same school with the same kids since 1 st grade.

come june he'll say good-bye to this familiar place. up next is middle school. >> do you worry about when he goes to a new school now that he's going to get teased? >> yes. >> how does a father prepare his son for that? >> we have to be strong. we have to make him strong, too. >> reporter: once victims, now a family full of strength. today the family appears safe, even happy. yusef's operations are covered by the california state children's services if you're curious as they would be for other children who live in california as well. they do face significant financial challenges. most of the apartment items were donated. if you want to help out, you can reach them on twitte twitter @youssifiraqi. you couldn't miss the excitement in rome over the new

pope francis. what you may not know is that pope francis also had part of one lung removed when he was a very young man. we're going to talk about it more. dr. kotri from the cleveland clinic, thanks for joining us. appreciate it. >> thank you. >> we don't have the details about this. he had h a serious infection in his 20s and had part of a lung removed. this is your area of expertise. what did you think when you heard that? how common was this at the time? >> when i heard how long ago it was and when i think about how wonderful he looked on the balcony and how inspiring he was, i thought what a role model not just as a healer in his role as the new pope francis, but also from the fact that someone who persevered from illnessed

and had surgery and it didn't cripple him. that was encouraging. >> most people don't realize that you are born with excess lung capacity. the body is resilient and redundant. most people use 30 to 40%. it's not like your heart where the whole muscle is crucial. you can remove a portion or maybe a whole lung without hurting the ability to breathe. pope francis, this hasn't slowed him down. he's also 76 years old and missing part of a lung. >> right. what would you advise for health concerns? >> what he's doing seems to be working well. talking to my pulmonary patients staying active, staying physically fit is helpful. making sure the rest of your body is fit and other chronic illnesses are managed well like diabetes or hypertension. basically making sure you are

taking proper precautions. get your nations, treating infections early. he'll be in the public so it will be difficult to avoid being around sick people. as long as he takes care of himself and gets proper care and immunezations he should be okay. >> get your flu shot, too. >> i say it every year. >> we'll remind the pope of that. thanks so much for joining us. >> happy to be here. tank you. coming up, something interesting known as cosmetic psychiatry. taking medicines you don't need so you can function better. she's still the one for you -

you know it even after all these years. but your erectile dysfunction - you know,that could be a question of blood flow. cialis tadalafil for daily use helps you be ready anytime the moment's right.

you can be more confident in your ability to be ready. and the same cialis is the only daily ed tablet approved to treat ed and symptoms of bph, like needing to go frequently or urgently. tell your doctor about all your medical conditions and medications, and ask if your heart is healthy enough for sexual activity. do not take cialis if you take nitrates for chest pain, as this may cause an unsafe drop in blood pressure. do not drink alcohol in excess with cialis. side effects may include headache, upset stomach, delayed backache or muscle ache. to avoid long-term injury, seek immediate medical help for an erection lasting more than four hours. if you have any sudden decrease or loss in hearing or vision, or if you have any allergic reactions such as rash, hives, swelling of the lips, tongue or throat, or difficulty breathing or swallowing, stop taking cialis and get medical help right away. ask your doctor about cialis for daily use and a 30-tablet free trial.

last week this story got my attention, i think in part because i have kids. two mom launched an online petition calling on kraft to remove two ingredients from the popular mac & cheese. a few hundred thousand people

signed on to this campaign. >> we found out kraft is using two ingredients in the u.s. version of mac & cheese, yellow number 5 and 6. but they are not using it overseas. >> yellow number 5 and 6 are artificial colors. they are fda approved but some critics say they are not benign. >> food dyes trigger hyper activi activity, inattention, templer tantrums, those behavior changes in some subset of children. even the food and drug administration now agrees with that. >> we decided to talk to kraft as well. they say, quote, the safety and quality of our products is our highest priority. we take consumer concerns very seriously. the company sells plenty of mac & cheese identical in taste and nutritional values ta doesn't have added food colors. for now the products are still in the box. we'll keep you posted if they are removed.

under the microscope today, cosmetic psychiatry is the use of prescription medications by people who don't need it. often times just to improve their focus, concentration. there is a new report that says it is parents pushing their kids to take the medications. parents need to listen to the story. joining me to talk about it from san diego, dr. allen francis of duke university and author of "saving normal." thanks for joining us, doctor. >> my pleasure. >> i have kids. you know, this is one of the most common topics when parents get together, it seems. let me start off with this question. with regard to the medications, are they risky to a child's health? >> well, the kid needs the medication, it's a great thing to have. it can be very, very helpful. but most of the kids who are getting treated for attention deficit disorder now don't need

it. certainly the cosmetic use of these medications for performance enhancement makes no sense at all. >> does it put their heart -- it's essentially amphetamines which is a type of speed to put it in context for the audience. is it risky? >> it can cause anxiety, sleeplessness, weight loss. in some kids it causes cardiac problems. the long-term effects are largely unknown. in some kids it may provoke manic episodes. in others it could be a risk factor for substance dependence, but the medication can be remarkably useful when used well for someone who is carefully diagnosed. what's happening now though is many kids aren't carefully diagnosed and they are getting the medicine unnecessarily. >> along those lines, a little bit of history. in 1994 you were chairman of the group that wrote what's known as the dsm-4, the bible, the manual that determines the criteria for

various types of disorders. since that manual came out, doctor, the diagnoses of adhd tripled. that feeds into the point that parents say, look, every kield now has adhd. is it because of the looser, broader definition of adhd? >> the rates have gone from 3% to 10%. 4% of kids get medication. we predicted a 15% chance. why has it tripled? two things happened we didn't anticipate -- expensive new drugs on patent came to the market. this gave the drug companies the means and motivationing to advertise very, very heavily. at the same time congress gave the drug companies a complete carte blanche to directly advertise to consumers as much as they wanted. we are the only country in the world that allows drug companies this degree of freedom.

they took advantage of it. they marketed it aggressively to doctors, to parents and teachers. this has created a bubble of add diagnosis with many kids inappropriately diagnosed and inappropriately medicated. >> i think you make a good point. it's interesting. we hear about this all the time with regard to adhd. other disorders as well. patients, doctors, teachers coopted in a way, thinking they are doing the right thing. but often times not. doctor, thank you. thanks for joining us. you know, a lot of parents out there, myself included. i think it's important to hear what you have to say. good luck with the book as well. >> thank you very much. appreciate it. coming up, we'll talk to a father who wrote movingly about being diagnosed with asbuperger syndrome and realizing he passed it to his son as well. hey! did you know that honey nut cheerios

has oats that can help lower cholesterol? and it tastes good? sure does! ♪ wow. [ buzz ] delicious, right? yeah. it's the honey, it makes it taste so... ♪ well, would you look at the time... what's the rush? bee happy. bee healthy. with clusters of flakes and o's. oh, ho ho... it's the honey sweetness. i...i mean, you...love. >> announcer: the human factor is brought to you by honey nut cheerios and by cancer treatment centers of america. care that never quits.

misfit, truant, delinquent. my next guest said he wasn't a model child and is not a model dad either but has plenty of parenting advice. he's a best selling author with a new book called "raising cub by" a father and son's adventure with asperger's trains, tractors and high explosives. thanks for joining us. >> thanks for having us on with you. >> let me talk about asberger's. all your life you knew you were different in some way, why until age 40 were you not diagnosed with asperger syndrome? why did it take so long? >> remember, i was born in '57. asberger's wasn't really talked about by psychologists and therapists in america until the

late '90s. i was 40 at the time. when my son was born in 1990 i didn't know about asperger's or autism either, but i saw in him the same behavioral differences i remember from my childhood though i didn't know they were autism. i knew how ied had struggles. i tried to advise him as best i could based on my experience, being the same way. >> cub by, i want to talk to you in a second. john, if i could ask about that. what were the behavioral things you recognized. cubby, i'm fascinated. in part as a neuro scientist. what were you looking for? >> well, first of all, i'd say i wasn't looking for anything. like any parent, you always hope your kid's better than you, brighter, cuter, smarter. when i would go with his mom and we would put him down at day care there might be two, three other kids on the floor next to

him. i thought maybe this would be like pouring goldfish into a tank and cubby would be swimming with them all mixed up. but he would stay by himself. that made me remember my own time as a little boy and how i wanted to engage the other kids and have friends and i didn't know how. i couldn't tell. was cubby wishing he could do it and not know how or did he truly not have interest? it was hard to know. i knew it was different and it was like me. >> it's fascinating. cubby, you have to excuse me. would you say you first noticed you were different from other kids? is that a fair way to characterize it? >> i didn't really learn it from them. i have always known it. i have always known he's different than all of my friends' fathers. my mother is different from my friends' mothers in a distinct way. i got the impression i'm not

quite the same type of animal, you know. >> i think cubby is fortunate because he thinks he's different. when i was a little boy i felt like i was defective which was a worse way to feel. >> that's interesting. i'm sure a lot of people at home watching the way you characterized that will be interesting for them. >> it's so common that people who are different are misinterpreted. whether it's somebody like cubby with a scientific curiosity twisted into imagined criminality or a young person his age with autistic speech challenges. an officer calls out to him h and he ignores him because he's autistic and they end up in a fight and the kid gets arrested when all he was doing was standing there. he didn't respond, not because he was trying to get something over on the cop but he was autistic and had speech challenges.

that's a tragedy. >> i appreciate you coming on. it's important for people to hear the discussion. it comes up a lot in our society. maybe more than ever. thanks. good luck with the book. everyone should read the book. >> thanks for having us on. >> next up, something to keep in mind before you go out and drink this st. patrick's day. anyone have occasional constipation, diarrhea, gas, bloating? yes! one phillips' colon health probiotic cap each day helps defend against these digestive issues with three strains of good bacteria. live the regular life. phillips'.

as well as they could because they don't take it with food. switch to citracal maximum plus d. it's the only calcium supplement that can be taken with or without food. my doctor recommends citracal maximum. it's all about absorption. just two months ago we set our six fit nation participants loose on their
