HIV's Hideout; Vitamin D- Fense; Does a Body Good
CHETRY: We say good morning to a nice sunny Washington, D.C., this morning. It's 38 degrees, but it is warming up. It's going to be a nice 60 degrees for a high today in the nation's capital. It's 47 minutes after the hour. It means it's time for your AM House Call, stories about your health this morning. There is new research showing doctors where HIV hides out in your body to avoid being killed off. They say it actually lurks in certain bone marrow cells while medications work to kill off the aids virus in the blood. This also helps explain why HIV isn't curable, at least not yet. And while HIV devastates the immune system, another new study is telling us how to keep your body's defenses strong and alert. Scientists at the University Of Copenhagen say vitamin D is crucial to arming and activating T cells in your body, and that without it, doctors say our immune system could remain naive to viruses and bacteria in the body. Also women can toast a new study that links wine to gaining less weight. Researchers studying more than 19,000 women found that moderate drinkers actually had a lower risk of obesity than those who stuck to mineral water. The research suggests that the liver breaks down the fat differently from other foods which affects weight gain. Old officials again stress, though, that moderation is the key.</s>ROBERTS: Yes. It doesn't seem to be just wine too. It's all alcohol. The liver apparently uses it differently.</s>CHETRY: They said that if they were rating it, though, people who drink red wine have the lowest weight gain and people that had spirits and beer actually had the most.</s>ROBERTS: Don't be knocking down those margaritas or if you are, just you know, --</s>CHETRY: That's right.</s>ROBERTS: Drink two, one for each hip, right. A check of this morning's weather headlines, Rob Marciano in the Weather Center for us in Atlanta. Good morning, Rob.</s>CHETRY: Hey, Rob.</s>ROB MARCIANO, AMS METEOROLOGIST: Good morning, guys. We've known this awhile, right. The French eat a lot of fatty food. They drink a lot of red wine, and they seem to be in decent shape, at least, by appearance. So yes, bon appetite and I salute. High pressure control across parts of the East Coast. Beautiful weekend finally after a long winter, that's for sure. Winter is not quite over yet, especially with the next storm just coming into the four corners out of the desert southwest, about to get into the central and southern plains. A little bit of fire weather, a problem with winds behind this, and some snow across parts of the higher elevations, but I shouldn't be too big of a deal, but it is beginning to tap some moisture from the Gulf of Mexico. So, rain is going to begin to spread across parts of the south with this, and they will get up into the central and northern plains as we go through the next 48 hours. We do have moist in the form of -- it's on the ground and that's creating some fog problems across parts of the Midwest if you're traveling through these airports; it's going to be some issues. Maybe a little bit of wind issues across parts of the northeast as well. JFK has one of the runways shut down so that tends to bog things down and Minneapolis and Dallas, you'll see a little bit of rain. Want to touch on what's going on across parts of Turkey. We had a pretty bad earthquake overnight last night, 5.9 magnitude, but it was a pretty shallow one. Check out some of the damage. Unfortunately, over 50 people were killed with this and more than that injured. African, Arabian, and Eurasian plates come together in this spot, so, it's typically a seismic hotbed, and you know, John and Kiran, our very active time right now, where we're seeing the earth move in a lot of different spots continues this time over in Turkey. Back over to you.</s>ROBERTS: All right. Rob, thanks so much. This morning's top stories just minutes away now, including many say it was the most important unfilled post in this administration. Now, President Obama has tapped the new chief for the TSA. Is it the right choice, though?</s>CHETRY: And at 24 minutes after the hour, an "AM original", Saving Carlos. In second grade and falling through the cracks, how the economic meltdown may keep a boy with mental health issues from ever catching up.</s>ROBERTS: And at half past the hour, they were the men who defended the fortress, the officers who stopped the men with guns and a vendetta from getting into the Pentagon. They are here to share their story live. Those stories and more coming your way at the top of the hour.
