sanjay gupta joins me now. how is grant doing today?at they told him, the doctors told his family that he wouldn't be able to do, he's now doing. it's extraordinary. and again, the er doctors had told his family to let him go. he's now running, he's speaking. he's made leaps and bounds above where he was just even a few months ago. >> do scientists or doctors know what effect omega 3's have on the brain? >> they have a good idea. talked to some scientists at the 2346789 ih, there's been some evidence that omega 3's in high doses can help prevent sells in the brain from dying. when you have a brain injury like this, you're building pressure in the brain, it can kill brain sells. so it can also act as an anti-inflammatory in the brain. but the most important thing, the thing i found most fascinating, the brain itself, in you look at it, about a third of it is made up of substances that are similar to omega 3 fatty acids. so essentially you're trying to replace the very substance that the brain is comprised of, with this thing that you can

airlines and goldman sachs. >> gupta was sitting on a call in october of 2008, in the middle of theinancial crisis, hearing how goldman sachs was going to get a $5 billion investment from warren buffett, arguably the most famous investor in the world. and here was rajat gupta, had that information secretly, and what does he do when the phone call ends? he hangs up the phone, he calls his friend, the hedge fund manager raj rajaratnam, and says, "you're not gonna believe what's happening. buffett's getting an investment into goldman sachs." so what does rajaratnam do? he loads up on goldman sachs stock, and when they announce it that evening, he's able to make a lot of money. >> buffett's berkshire hathaway is now saying it is buying a $5 billion stake in goldman... >> $5 billion of preferred stock... >> it's a huge surprise... >> the next day, raj gets on the phone with one of his traders in asia, and he's so proud of himself. >> narrator: prosecutors allege that gupta had a financial interest in passing rajaratnam insider tips. he was convicted on insider trading charges, but is now

back to you. >> all right, thanks so much, sanjay gupta.njay's report, a lot of people have been very confused about what exactly brain dead means, and my guest says we need to talk about that. i'm joined by bioethicist arthur capl caplan, director of ethics at nyu medical center. good to see you again, dr. caplan. >> thanks, fredricka. >> in is a tragic case, but you say there's confusion about terms of brain dead and life support, it leads to the outcome that makes no sense, in your view, ethically. so we heard sanjay's explanation. brain dead really does mean dead. so why even use that terminology? and what do you mean when you say it really makes no sense ethically, this predicament? >> the predicament we're in is that the family can't accept the death. you know, their little girl went in for an elective operation, she's died. they find it really tough and they're religious, hoping for something to happen. i understand that. it's tragic. but death is death. brain death is one way that we can diagnose it, stopping -- when your heart stop

i skipped over christina gupta who is senior health planner from the department of public health. >> thank you supervisors. so, i just wanted to give you a little bit of background this afternoon about why the public health field has been looking at sugary drinks as an issue. i wanted to start talking about what happens to sugar when it's in our bodies. sugar suppresses our bodies ability to consume fat. our body is the first one -- do you have an extra copy of the pregnancy -- presentation that you are making? >> i will make copies. >> so it suppresses our ability to burn fat. so when we eat sugar in high quantities our body priorities first burning the sugar before it starts burning the food that you might consume with that drink. so let's say you have a frappuccino with breakfast and a bagel. your body is not going to start working on that other food. if you haven't fully processed that by the time you have your next sugary item. that other food may not get processed and turns into fat in your body. next, the way that sugar is metabolized is different than natural sugars. it's oft

sanjay gupta and senior legal analyst jeffrey toobin.learly the laws have changed, public opinion has changed nationwide. where is the science on whether pot is addictive and what it might do to the brain? >> science is emerging but i'll preface by saying look, this has been illegal for a long time in this country. science is hard to come by. that's part of the problem. having said that, you know, if you look at addiction sort of across the board, addiction sort of means not only the idea someone is addicted to something, they will have physical withdraw if you take away the substance, but is it interfering with the way of life? do they seek out a substance and to get it, it will interfere with things they should do as part of their normal lives. marijuana across the board, 9% of people will become addicted to it compared to heroin which is closer to 23%, cocaine is in the 20s, alcohol 15, 16% depending on studies you look at. it is addictive, but maybe not as addictive as other substances. >> the law is setted in colorado, it is legal f

sanjay gupta. good to see you. what kinds of risks do people face when the temperatures drop as low as they're getting and as low as we will see them in parts of the midwest and northeast tonight? >> well, the two big ones, as you might expect, are hypothermia and frostbite. the thing about when you talk about these conditions, they can occur at varying temperatures and different people are going to be susceptible but as a general rule of thumb, when you talk about some of the temperatures that we're talking about, negative 30 at that football game, for example, on sunday with the wind chill, in as little as 15 minutes, you can start to develop frostbite so just an exposed part of the skin can develop that problem pretty quickly. they talk about this idea of layering, loosely layering clothes to keep warm air trapped inside, wearing a hat because 20% of your body heat is lost through your head, making sure you eat a big meal because eating actually helps generate heat, body heat, whereas drinking alcohol has the op
