New images of Pluto have arrived from a NASA space probe, and they're already allowing scientists to update what we know about the dwarf planet — such as its size. NASA's New Horizons probe has traveled more than 3 billion miles to send photos and data about Pluto back to Earth.
Mamie Parker, a former assistant director of fisheries and habitat conservation at the U.S. Fish and Wildlife Service, was the first African-American to head a regional office for that agency.

A recent recommendation from doctors in the United Kingdom raised eyebrows in the United States: The British National Health Service says healthy women with straightforward pregnancies are better off staying out of the hospital to deliver their babies.

Our days are full of things to remember, and they don't always arrive in an orderly fashion. Perhaps you begin your commute home and remember that you need to pick up milk. But then immediately, another to-do springs to mind: You never called back your friend last week.

So, what does a happy tarantula hawk look like? Ben Hutchins, an invertebrate biologist with the Texas Parks and Wildlife Department, takes NPR's Wade Goodwyn through all the gruesome wasp-on-tarantula details.
