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 staff at Deadspin, a sports news blog that also covers culture, media and politics, revolted on Tuesday after management told the site's employees to steer clear of stories that do not have a connection to sports.Instead of heeding management's mandate, staffers filled Deadspin's homepage on Tuesday morning with non-sports stories that had been popular in the past, seemingly a nod to their argument that stories that are not strictly about sports have been favorites of Deadspin's regular readers. Perhaps most telling among the selections was "The Adults In The Room," an 592

The United States and South Korea are expected to announce in the coming days that annual military exercises between the two nations are to be scaled back, according to a US defense official.The large-scale military exercises, known as Foal Eagle and Key Resolve, had been scheduled for this spring but according to the official, they will be scaled down to a small unit level and could involve virtual training.Defense officials say they can achieve the necessary training goals through the scaled-back exercises.The announcement is expected to come soon after President Donald Trump walked away from negotiations with North Korean leader Kim Jong Un in Vietnam.The US has already suspended several larger military exercises as part of an effort to ease tensions with North Korea following the last year's Singapore summit between the two leaders.In a news conference following last June's summit Trump called the exercises "provocative," stating, "It's inappropriate to be having war games."Trump has also questioned the usefulness of the exercises, citing the disproportionate share of the cost borne by the US.Former Defense Secretary James Mattis told reporters last November that the 2019 version of the Foal Eagle exercise was being "reorganized a bit" to keep from "being harmful to diplomacy."On Friday Defense Department officials refused to comment publicly about the status of the joint exercises but said they will proceed unless Trump specifically orders them canceled. "The (US-South Korean) alliance remains ironclad," said Pentagon spokesman Lt. Col. Dave Eastburn, when asked about the exercises. "Our forces maintain a high state of military readiness and vigilance in full support of a diplomatically led effort to bring peace, prosperity and stability to the Korean Peninsula."Earlier this month the US and South Korea reached a preliminary agreement on the cost of keeping nearly 30,000 troops in South Korea.Under the revised Special Measures Agreement, South Korea would boost its financial contribution to nearly billion, according to a State Department official and South Korean media. That's an increase from the roughly 0 million it had been paying per year during the previous five-year commitment.In an early February interview with CBS, Trump said he has "no plans" to withdraw US troops from South Korea and claimed to have "never even discussed removing them," but said "maybe someday" he would withdraw US forces from the country."I mean, who knows. But, you know, it's very expensive to keep troops there," Trump said, even though US military officials have said it is cheaper to house those troops in South Korea than in the US. 2682

This is the extraordinary tale of how a massive, strange-looking fish wound up on a beach on the other side of the world from where it lives.The seven-foot fish washed up at UC Santa Barbara's Coal Oil Point Reserve in Southern California last week. Researchers first thought it was a similar and more common species of sunfish -- until someone posted photos on a nature site and experts weighed in.What transpired after that surprised researchers from California to Australia and New Zealand.It turned out to be a species never seen before in North America. It's called the hoodwinker sunfish."When the clear pictures came through, I thought there was no doubt. This is totally a hoodwinker," said Marianne Nyegaard, a marine scientist who discovered the species in 2017. "I couldn't believe it. I nearly fell out of my chair."How the hoodwinker got its nameNyegaard spent years chasing the hoodwinker sunfish before she located and named the fish. All cases of the big fish were found in Australia, New Zealand, South Africa and Chile, she said. Except for one time in the 1890s, when drawings and records documented the fish appearing in the Netherlands.Scientists say there are five species of saltwater sunfish, and they come from different places. One enjoys tropical waters, another likes the subtropics and the hoodwinker prefers temperate water, Nyegaard told CNN. She works in the marine division at the Auckland War Memorial Museum in New Zealand."This is why it's so intriguing why it has turned up in California," she said. "We know it has the temperate distribution around here and off the coast of Chile, but then how did it cross the equator and turn up by you guys? It's intriguing what made this fish cross the equator."The antics of this wayward fish are comical, especially considering how the species got its name.As Nyegaard researched the fish, she realized some species of sunfish had been misidentified. One species that was thought to be rare was very common, while another fish thought to be common was misidentified, she said."It had gone unnoticed because no one really realized it looked different. There's a long history of confusion about the species in the sunfish family," Nyegaard said. "This fish had managed to stay out of sight and out of everybody's attention. It had been taken for mola mola (an ocean sunfish) so it was hoodwinking us all."And a bit of hoodwinking is what it was doing to researchers in California, too.Scientists first thought it was a different type of sunfishAn intern at Coal Oil Point Reserve alerted conservation specialist Jessica Nielsen to the dead beached sunfish on February 19. When Nielsen first saw it, the unusual features of the fish caught her eye."This is certainly the most remarkable organism I have seen wash up on the beach in my four years at the reserve," Nielsen said in a UC Santa Barbara press release.She posted some photos of the fish on the reserve's Facebook page. When colleague Thomas Turner saw the photos later that day, he rushed to the beach with his wife and young son.Turner, an evolutionary biologist who is six feet tall, stretched out his arms to show the scale of the seven-foot-long fish. He snapped some photos of what he thought was an ocean sunfish, a rare sight up-close, he said."It's the most unusual fish you've ever seen," said the UC Santa Barbara associate professor. "It has no tail. All of its teeth are fused, so it doesn't have any teeth. It's just got this big round opening for a mouth."Turner posted his photos on 3545
