AIDS is a chronic, life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight off viruses, bacteria and fungi that cause disease. HIV makes you more susceptible to certain types of cancers and to infections your body would normally resist, such as pneumonia and meningitis. The virus and the infection itself are known as HIV. "Acquired immunodeficiency syndrome (AIDS)" is the name given to the later stages of an HIV infection.
An estimated 39.5 million people have HIV worldwide. And though the spread of the virus has slowed in some countries, it has escalated or remained unchanged in others. The best hope for stemming the spread of HIV lies in prevention, treatment and education.

Shameen's brown eyes seem lost as she thinks about the one day she wants to forget, but it is all she can think about.
Still traumatized, she recounts the events that led her to a safe house in Kabul.
She was raped and nearly stabbed to death by her husband just seven days before we met her.
Her lips are quivering and her eyes full of fear.
"He forced himself on me," she said. "All I could do was scream."
She was married off 15 years ago when she was a teenager.
Throughout those years she was tortured and abused, suffering daily beatings with an electrical wire or the metal end of a hammer.
This was her normal life.

A vaccine to prevent HIV infection, the virus that leads to AIDS, has shown modest results for the first time, researchers have found, raising hopes that a disease that kills millions every year may someday be beaten.
In what is being called the world's largest HIV vaccine trial ever - involving more than 16,000 participants in Thailand - researchers found that people who received a series of inoculations of a prime vaccine and booster vaccine were 31 percent less likely to get HIV, compared with those on a placebo.
"Before this study, it was thought vaccine for HIV is not possible," Colonel Jerome Kim, who is the HIV vaccines product manager for the U.S. Army, told CNN.
HIV is the human immunodeficiency virus, which is the virus that causes AIDS - acquired immune deficiency syndrome.

A 20-year-old from Northern California is suspected of brutally killing four people. Richard Samuel McCroskey is a musician who calls himself 'Pyscho Sam' on YouTube. His lyrics are offensive and included messages about abuse, rape and killing. Authorities say he is accused of carrying out the same type of crimes about which he rapped.
The type of music that McCroskey practiced is known as the "Horrorcore" genre.

Sales of previously-owned homes fell in August, snapping a four-month streak of increases.
Existing home sales fell 2.7% last month from July to a seasonally-adjusted annual rate of 5.1 million units, but were up 3.4% from a year ago, according to the National Association of Realtors.
Sales had jumped 15.2% in the previous four months.
Lawrence Yun, the NAR's chief economist, said the drop may reflect delays in completing sales due to tough lending standards and new rules for appraisals.
Nationwide sales are up nearly 14% from their bottom in January, but are still down nearly 30% from their peak about four years ago. For the housing market to stabilize, Yun says sales would need to rise to a pace of around 5.5 million to 6 million.
Additionally, the median sales price was $177,700, down 12.5% from $203,200 in the same month last year.
One bright spot in the report: Despite the decrease in sales, the supply of homes on the market fell significantly in August. Total housing inventory fell by 10.8% to 3.62 million existing homes for sale. That's an 8.5-month supply, down from a 9.3-month supply in July.

Well, hello ... Dalai!"
It seemed like a good idea at the time. And with hindsight being 20/20; it still does.
How often to you get to meet an international figure as captivating as the Dalai Lama? I wanted to make an impression, and break the ice, in my Southern hospitality sort of way.
So enter the lyric from the song and the fist bump now heard round the world.
I had been told by his representatives that the Dalai Lama had a wonderful sense of humor, and would enjoy the exchange. Indeed, he did. His Holiness laughed, returned the gesture, and gave me his blessings.
And in our brief time together, I saw in his eyes the sparkle of kindness, love and good humor.

The United Nations General Assembly continues today. Afghan President Hamid Karzai, Venezuela’s Hugo Chavez and Georgia’s Mikheil Saakashvili are among the leaders slated to speak. Based on yesterday’s speeches, should we conclude the world is safer or crazier?
World leaders will begin to head from New York to Pittsburgh for the G20 meeting today and tomorrow. President Obama promises to push world leaders for a reshaping of the global economy in response to the global economic crisis. Protesters are already out in full force in the Steel City – four people attached to a giant banner protesting the meeting were seen dangling from a bridge.
Before he makes his way to the G20, Obama is chairing the UN Security Council for a session on nuclear proliferation and disarmament this morning. He’s seeking broad consensus to contain the further spread of nuclear weapons. Iran is in the limelight right now – it appears Russia may likely help the U.S. curb Iran’s nuclear ambitions and Iran says it’s willing to have its nuclear experts meet with U.S. and other global scientists. Is this a sign of progress? Libya is among the Security Council members – could we hear another soliloquy from Moammar Ghadafi?
