Update 3:35 pm August 10: Two days after making a few general remarks about the opioid crisis, President Trump on Thursday called it "a national emergency" and said his administration would be drawing up papers to make it official.

"We're going to spend a lot of time, a lot of effort and a lot of money on the opioid crisis," Trump told reporters at his golf club in Bedminster, N.J.

Many believe this dinosaur is the largest to ever walk the Earth.

It would have weighed more than 10 African elephants put together and had a thighbone taller than the man who helped dig it up. And, fair warning, it stands at such a remarkable height that it might take a little scrolling to get through its portrait.

Most of us think of jellyfish, when we think of jellyfish, as something to be avoided at the beach (or as the protagonists in that one episode of Friends).

Even marine biologists have historically cast aside these bothersome interlopers when conducting surveys of more "important" ocean species.

It's the right time of year to enjoy delicious tropical fruit.

But for now, U.S. consumers should avoid Maradol papayas imported from Mexico, according to the Centers for Disease Control and Prevention.

More than 100 people in 16 states have been sickened by strains of salmonella that U.S. health officials say are linked to the papayas.

I entered the packed cafeteria with tray in hand, searching for the right food to eat.

Around me, hundreds of people of all ages spoke excitedly in dozens of different languages, commenting on each other's ideas, asking questions, and thinking of the next steps in their research programs.
