Can a coronavirus pandemic be stopped?

First thing’s first: What's a pandemic? It’s the worldwide spread of a new disease, according to the World Health Organization (WHO).

Now that that’s out of the way: The deadly coronavirus could cause “severe” disruptions in the U.S., a federal health official warned Tuesday as global experts struggled to fend off the outbreak and avoid a pandemic.

But is it too late? The coronavirus already has caused sickness and death, and it has sustained person-to-person transmission. That's two of the three factors for a pandemic, said Nancy Messonnier, the CDC’s immunization chief. Other experts are also warning that avoiding a pandemic is “very unlikely” at this point.

President Donald Trump downplayed coronavirus concerns on Tuesday, saying it was "very well under control in our country," despite a sharp rise in cases globally that prompted the biggest one-day drop in the Dow Jones Industrial average in two years.

Get your popcorn ready, the Democratic debate is upon us

It’s showtime (again) for the Democrats. Seven Democratic presidential hopefuls take the stage Tuesday night ahead of the South Carolina primary on Saturday. The debate will reunite six contenders from last week’s heated match-up in Nevada and will welcome billionaire Tom Steyer back to the stage. Which candidates could come out on top? Former Vice President Joe Biden still leads the South Carolina primary race, according to polls, while the clear frontrunner nationally is Bernie Sanders, who won the popular vote in the first three nominating contests. The debate is scheduled to begin at 8 p.m. EST.

Tom Brady shared an emotional tribute to Kobe Bryant

A day after thousands mourned Kobe Bryant and his daughter Gianna at Staples Center in LA, future Hall of Fame quarterback Tom Brady shared an emotional tribute reflecting on the NBA star's legacy. Brady, an NFL free agent for the first time in his career with the New England Patriots, called Bryant a "real-life superhero" and said he's been "deeply affected" by Kobe's passing. In his tribute, he tried to put into words exactly why.

A parasite with no DNA that doesn't need oxygen? Creepy

Scientists have discovered the only known animal that does not need oxygen to survive, a tiny little parasite that largely preys on salmon. The study, published Tuesday, found that the critter doesn’t require “aerobic respiration” to survive – a revelation that may change how we understand life on Earth and beyond. Another fun fact about the parasite: It’s the first multicellular animal found in the wild to not have the DNA, which contains the genes responsible for respiration.
