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 US Food and Drug Administration is proposing new regulations on over-the-counter sunscreens in an effort to keep up with the latest scientific and safety information.The proposal, announced Thursday, is available for public review and comment for the next 90 days and addresses the safety of common sunscreen ingredients, as well their dosage forms, sun protection factor (SPF) and broad-spectrum requirements. It also addresses labeling, aiming to make it easier for consumers to identify key product information."Since the initial evaluation of these products, we know much more about the effects of the sun and about sunscreen's absorption through the skin," FDA Commissioner Dr. Scott Gottlieb said in a statement.Over-the-counter sunscreen drug products are regulated by the FDA under the 810

The Taliban is claiming responsibility following the death of a US service member in Afghanistan on Monday, even as peace negotiations between the Taliban and US continue.US and Afghan government forces were targeted with IEDs while conducting a raid in the northern province of Kunduz, according to Taliban spokesman Zabiullah Mojahid.The US military early Monday confirmed that a service member was killed in action. The name is being withheld until next of kin is notified.Between 12,000 and 13,000 US troops are currently serving in Afghanistan as part of a US-led NATO mission to train, assist and advise Afghan forces.At least 20 Americans have been killed in combat in Afghanistan in 2019, and there have been more than 2,400 total deaths of US service members since the start of the 18-year war.The Taliban has continued to carry out attacks despite ongoing peace talks with the US.President Donald Trump announced late last month 951

The Smithsonian Institution is working to document history as it happens. It's asking ordinary people and organizations to set things aside that will help tell the story of COVID-19.“America will not be the same after this event,” said Alexandra Lord, Chair and Curator of the Medicine and Science Division at the National Museum of American History. Lord says a task force is looking for items that will show the full impact of the coronavirus. They've been in touch with the U.S. Public Health Service to hold onto medical supplies, like ventilators, test kits and masks.Objects from corporations and small businesses can help show the massive economic impact.Curators are even looking into how to document working, learning and spending time together through Zoom calls.“We have access to all sorts of technology that enables us to talk to family and friends, and that's really different from past pandemics,” said Lord. “We really want to mark that in some way.”Right now, curators are just flagging the objects they're interested in. They'll start physically collecting once their offices reopen, but there's no cutoff to stop.“In fact, it's more than probable that 40, 50 years from now, curators at the Smithsonian may find objects in someone's attic that were related to COVID-19 and we may feel at the time, this is a really fabulous object we really want to bring it in to the museum,” said Lord. Some objects will be included in a previously planned exhibit called "In Sickness and in Health." That's scheduled to open in 2021.If you'd like to suggest something for curators to consider, send an email with pictures and description to 1658
