the suspect in the head. >> we waited it will the last second in our opinion to use deadly force. it's a case that could be red from a hollywood script although there's grocery stores throughout the united states. it could happen anywhere. it happened in midwest city and our proud our agency we responded the way they did. coming up in 30 minutes from now, a conversation that may make some people uncomfortable. it's about these words that have been used a lot. it's a conversation that we need to have and i hope you'll watch. see you back here at the top of the hour. welcome. lots to get to including this. doctors working construction and flipping burgers in the united states instead of practicing medicine. i'll tell you why more of them could soon be seeing patients. an amazing way to study the brain. you can see new connections being made. a crackdown on pharmacy

websites selling popular medicines that are not what you think they are. this week the food and drug administration shut down 1600 websites that were selling illegal, unapproved or counter amphetami feit drugs. the problem isn't new but it's only getting bigger. behind too many websites is this. counterfeit medications made in peru, columbia, china often in back alley shops under filthy conditions. to get these fakes into your medicine cabinet, counterfeiters have to first get them across the board. here in los angeles we have one of the largest famail facilitie. >> it's getting worse in. >> the problem is getting worse. >> reporter: they are separating products to be screened with a

device that can identify counterfeit drugs on the spot. >> are you able to screen everything that comes through? >> we try to screen as much as we can. before we would have to send it to the lab and that could take weeks. we're able to do it in a few minutes here. >> reporter: the national association of boards and pharmacy says that most fakes come through online sales and that 97% of online sites don't comply with state and federal laws. >> they're offering prescription drugs without a prescription. they're selling unapproved fda drugs. drugs the fda has not found safe or drugs that are not even allowed in the u.s. market. >> reporter: often the draw is cheaper prices and claims the drugs are coming from canadian pharmacies which most americans consider safe. >> the drugs that they are shipping to consumers, they believe are coming from canada and have been approved by health canada are really drugs that are coming from places that you

would never believe and never suspect. >> reporter: in the fight to stop fakes the fda gets help from pharmaceutical giants like pfizer. they know counterfeits can help the bottom line. john clark says his people found counterfeit versions of 60 different pfizer drugs from last year. that's up to 20 from 2008. >> the better counterfeiters might put in 10, 20 even 30% of the active pharmaceutical ingredient that's supposed to be in the medicine. >> reporter: they test,0 thousas of products a year. it found fake cancer, fake heart, fake cancer drugs and even fake chapstick. >> they will do a number of testing. fp the packaging doesn't

demonstrate it's counterfeit then they go to the medicine itself. >> reporter: this is an audio clip that pfizer gathered. >> we can still make 50,000 pill a month. and that's by hand. >> reporter: the company shares information with law enforcement which conducts the actual raids and makes arrest. those counterfeiters were caught but plenty are not. >> joining me now from fda headquarters dr. margaret hamburg. do you know of actual harm of someone taking these medications? >> absolutely. these products can have none of the active ingredient that people need. they can have too much or too little. they can have toxic ingredients. they can prevent patients from getting the actual medications that they badly need to treat

their disease. moreover with certain kinds of treatments sub standard drugs, counterfeit drugs can put us at risk by enhancing the problem of drug resistance. this is true with a disease like malar malaria. these issue affect people every single day. >> even if they are not getting harmful ingredients, they could be problematic but they think they are treating their [ bleepblood pressure and they are really not. you announced crackdown for 1600 websites for selling illegal drugs. >> absolutely. >> they would have a website and be taken down, they would just come up with another one. how do you make sure they don't just pop up with a different name? >> it's a huge problem. you're absolutely right. you close one down and it can pop up somewhere else.

we need relentless attention. we also need to enhance public awareness. that's why i'm glad you're doing this story because consumers need to know that sadly the majority of websites that they are going to encounter when they search the web looking for an online pharmacy are most likely rogue. they are not setting fda approved products and they are operating illegally and potentially purchasing from these sites put people at risk. >> you've mentioned this before but if you find a site that does not ask for prescription, is selling a product that's not fda approved those should be big red flags. i think 97% of these websites could have some sort of fraudulence in that way. when you talk about websites, that's one particular thing but people use those sites because it's expensive. these medications are pricey. i know my own family has done that. is there something they can look for on a site that's credible instead of saying 97% are bad.

we know these ones are good. >> right. that's so important. there are things consumers can look for. number one the website should ask for a valid prescription. if they don't beware. the pharmacy, the website pharmacy should be located in the united states. they should have a license licensist pharmacist available for communication. you're not assured of a safe product and a legally operating website pharmacy. >> thanks so much for joining us. appreciate it. every day it seems we're talking about a gene that does this or that. it was less than a lifetime ago that scientists first figured out the basic code for which our genes are written. dna was first described by

francis crick and james watson. as we celebrate its 60th anniversary here is james watson as he talks about his life's work. >> i was inspired to go into science because i wanted to understand the world about me better. i wanted to know how birds did migrate. i learned that when i was something like 8 years old it seemed a big puzzle. they didn't share my conviction only dna was important. there are no monks copping things inside sells. somehow the cell had way of

copying its information. we knew it has a structure. it was a helix that they first around. i think early on i wanted to do something important with my life. i still wanted to think about science and really nothing else. being driven by finding the truth. that's my legacy. the truth. sometimes you don't find it. you'll always have that as you start with the truth it's helpful. >> james watson there. just in his mid-20s when he did some of that amazing research. immigrant doctors forced to work construction in odd jobs as we have a shortage of positions in this country. i'll show you one possible solution. stay with us.

congress in the country are in the middle of a hot debate. where ever you stand on this issue it has a direct connection to another problem. that's our doctor short aj in the united states. turns out there's thousands of medically trained doctors living in america but not practicing medicine. >> we've always wondered there's so many international medical graduatesworking in america, where are they. >> this is a woman working at mcdonald's in colorado. they are on the hunt for latino immigrant doctors. >> why? >> potentially as a solution to america's primary care doctor shortage. there's a few thousands immigrant doctors living in southern california alone.

they aren't practicing medicine anymore. instead of treating patients many spend years cleaning houses, working on construction sites and in fast food chains. they work for ten years and come here. they're not licensed. >> jose was a doctor in el salvador with more than eight years of training when he moved to the united states in 2005. >> i'm going to call this patient to let hem know we will refill. >> prior to last year he wasn't working in this u.s. hospital or any hospital. instead. >> i will do anything you ask me to as long as it's legal and you pay me for it. i was cleaning houses painting, doing flooring. >> for years he juggled odd jobs during the day with studying for

the u.s. medical boards at night. >> working eight to ten hours a day or try to study eight to ten hours at night. it's really impossible. >> all residents are required. time consuming process that most aren't prepared for. >> it helps fast track these. it provides medical board prep classes and mentoring by ucla physicians. >> when i get accepted i was able to stop construction. that gave me the opportunity to take the test six months after joining the ucla program. >> they've helped 66 latino immigrant doctors including chavez pass the medical boards and get placed in residency boards in southern california.

that's a desperate need there. in riverside county there's one m.d. for every 9,000 people. now, dr. chavez gets to be one of their physicians. >> if you're wondering this ucla program is funded by private donations. here is another number to think about. with obama care an estimated 25 to 30 million new people will have health coverage next year and they will be looking for doctors. the shortage is important. it's probably going to get worse before it gets better. imagine being confined to a wheelchair your whole life and someone gives you a chance to get out. now you have a sense what ryan chalmers felt. he was born with spina bifida. that's an incomplete closure of

awareness and being able to meet people is what made it all worth it. it was just thinking about the people being impacted. >> you have raised about $500,000. what happens next? >> over the next couple of weeks i will go with the stay focus program. we'll trying to make it sustainable. the founder of the organization, this is the ten-year annivers y anniversary. it's changed my life. the organization has changed my life. i just want to be able to make a difference and go forward. >> are you aiming for it in 2016? >> that's the plan. that's the goal for the next three years is focus on rio. >> we'll keep an eye on you. up next an incredible new look at the wiring of the brain. mom, dad told me that cheerios is good for your heart,

welcome back. president obama announced he would commit $100 million to create a detailed map of the human brain.

i got a chance to visit the neuro imaging lab. it looks amazing. how much progress have we made over the last ten years? >> i think it's been amazing because the technology to acquire detailed images of structure and function have been unprecedented. we can look at very small regions as small as a millimeter or smaller in a living human individual and we can relate not only what we see in terms of a the person's anatomy but how it works. how they are interacting with other functions of the brain. >> this is pretty spectacular. what are we looking at? >> you're looking a ining at tr. you're looking at the fibers that connect different regions. it allows us to see what is connected to where.

>> talk about function like movement and sensation. what about things that are a little more self-awareness, happiness, pain and we regard. is this going to help better identify those areas? >> i hope so. obviously one has to start with a map initially. it's like making a map of the earth. we find where the continents are. now we can with our gps systems find specific roads. we can even look at the amount of traffic on those roads. that's a very good analogy. we first have to create these big maps that show us the overall picture of how it is. >> what does this mean for the average person? >> i think it's important for us to undertake a challenge. the population is getting older. it's an increased percentage of

people with alzheimer's. this kind of science lays the foundation for us to look for targeted therapies and really is constructive this terms of improving the health and well being of everyone. >> the physical structure is one part of the understanding of the brain. it's daunting for sure but it could someday change the way we understand ourselves and maybe the way we practice medicine in a very real way. before you head to the beach this summer what you need to know. f things. all waking up. connecting to the global phenomenon we call the internet of everything. ♪ it's going to be amazing. and exciting. and maybe, most remarkably, not that far away. we're going to wake the world up. and watch, with eyes wide, as it gets to work. cisco. tomorrow starts here.
