They're the hallmark of vaping — the massive clouds that sometimes come in different shapes.But how does a little e-liquid become those clouds?We're going inside an e-cigarette to find out.The devices usually have four main parts: a reservoir that holds e-liquid, a battery, a heating element and a mouthpiece.The first step is to add e-liquid to the reservoir or to attach a pre-made cartridge.The liquid is made of nicotine, flavoring, vegetable glycerin and propylene glycol. You’ll find propylene glycol in things like inhalers and fog machines. The U.S. Food and Drug Administration says it’s all safe.Next, the battery warms up the heating element and that vaporizes the e-liquid. The vapor travels through the e-cigarette, out the mouthpiece and into the lungs.When exhaled, the vapor vanishes into the air fairly quickly.The heat is low enough that it doesn't combust — or burn — the liquid.Supporters say vaporizing creates fewer dangerous compounds than combustion.The American Cancer Society says vapor can still contain harmful chemicals or substances, like volatile organic compounds, or VOCs.They cause inflammation and can make the kidneys, liver or nervous system fail.According to the American Cancer Society, vapor can also contain harmful flavoring chemicals and formaldehyde. 1312

The red meat or white meat debate is a draw: Eating white meat, such as poultry, will have an identical effect on your cholesterol level as eating red beef, new research indicates.The long-held belief that eating white meat is less harmful for your heart may still hold true, because there may be other effects from eating red meat that contribute to cardiovascular disease, said the University of California, San Francisco researchers. This needs to be explored in more detail, they added.Non-meat proteins such as vegetables, dairy, and legumes, including beans, show the best cholesterol benefit, 612

Three members of the New York Police Department have died by suicide in less than 10 days, Police Commissioner James P. O'Neill said Friday.Last week, a respected chief and an experienced detective died within 24 hours of one another, O'Neill said. Friday, a "promising 29-year-old police officer with six years on the job" died behind the NYPD precinct in Staten Island, where he worked, the commissioner said."This is a mental-health crisis. And we -- the NYPD and the law enforcement profession as a whole -- absolutely must take action," O'Neill said 566

The West Texas man who killed seven people and wounded 25 in a shooting rampage bought his gun in a private sale, which doesn't require a background check, a law enforcement official told CNN.Police have described the firearm Seth Ator, 36, used in Saturday's killing spree in and around Odessa, Texas, as an AR-15-style rifle.Ator tried to buy a firearm on January 14, 2014, but wasn't allowed to, the Texas Department of Public Safety told CNN in an email.The department is prohibited by law from disclosing the reason he was denied the purchase, the DPS said.Ator failed a background check when he applied to get a gun, a representative for the Bureau of Alcohol, Tobacco, Firearms and Explosives said Monday, without giving details.The ATF, the FBI and the DPS are "aggressively following up on" the source that supplied the firearm to Ator, the ATF representative said.Investigators are still searching for a motive in the mass shooting.The man showed up to work Saturday "in a distressed mental state," and was fired, said FBI Special Agent in Charge Christopher Combs.Speaking at a press conference Monday, Combs said the firing wasn't the reason for the shooting spree and that he was "already enraged" when he showed up for work.Ator had been 1264
