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 top US trade negotiator on Tuesday said that new tariffs on 0 billion in Chinese-made consumer goods including cell phones, toys and video game consoles would be delayed until December 15.The move comes after a phone call between US Trade Representative Robert Lighthizer, Treasury Secretary Steven Mnuchin and top Chinese negotiator Liu He in which the parties agreed to pick up negotiations by phone within two weeks, according to a statement from the Chinese Commerce Ministry.President Donald Trump said earlier this month that he would add a 10% tariff on an additional 0 billion of Chinese-made products on September 1, which would effectively put a tax on all Chinese goods coming into the United States.Last year, Trump imposed tariffs on about 0 billion in Chinese-made goods, targeting industrial materials and components."Trade talks are continuing, and during the talks the U.S. will start, on September 1st, putting a small additional tariff of 10% on the remaining 300 billion dollars of products coming from China into our country," he 1076

There really have been a couple of creepy stories in recent days about hackers breaking into people’s Ring security cameras.“There is actually a channel that someone has put together, like a YouTube channel, of hacked-into security cameras,” says Bob O’Donnell, the president of TECHnalysis Research. “And they’re trying to do it for fun and they’re harassing the people. I mean, it’s really sick.”O’Donnell says it’s not likely this has anything to do with security camera system, but rather how the owner sets them up. “People who are just using the basic default settings or doing no password because the convenience of wanting to get in there to change their settings, are leaving themselves open for people to come in from the outside,” the tech expert says.Hackers often reuse stolen or leaked credentials. They could get the info from past data breaches that expose usernames and passwords that people use on multiple devices.O’Donnell says people should change their security camera passwords regularly and set up two-factor authentication.“Basically, it means the equivalent of like a fingerprint scan and a password or a hardware key and a password, or a facial scan and a fingerprint,” O’Donnell says. “Bottom line is it’s two different things you need to get into to access your account.”O’Donnell says the bottom line is security cameras do bring peace of mind and convenience when they’re managed properly. 1433
