A tablespoon of soil contains billions of microscopic organisms. Life on Earth, especially the growing of food, depends on these microbes, but scientists don't even have names for most of them, much less a description.

That's changing, slowly, thanks to researchers like Noah Fierer, at the University of Colorado, Boulder. Fierer think microbes have lived in obscurity for too long. "They do a lot of important things for us, directly or indirectly, and I hope they get the respect they deserve," he says.

On Thursday, USA Gymnastics announced they will stop using the Karolyi Ranch — the site of many of the atrocities committed against Olympians by Larry Nassar, the team's former doctor. NPR's Kelly McEvers talks to New York Times reporter, Juliet Macur about what happens next as Nassar faces sentencing hearings this week.

There was a time when saying you lived in Portland, Ore., would get a response like, "That's above California, right?" Now, people not only know where the city is but also inevitably ask, "Is it just like the show?"

Attention Drivers: Many of those those freeways you're using may not be free for long. Several states are opening new toll roads this year and rates on many existing turnpikes and tollways are going up.

With the death of biologist Mathilde Krim on Monday, at the age of 91 at her home in New York, the world lost a pioneering scientist, activist and fundraiser in AIDS research. She is being widely praised this week for her clarity, compassion and leadership.

Amid the panic, confusion and discrimination of the HIV epidemic's earliest days, Krim stood out — using science and straight talk, in the 1980s and beyond, to dispel fear, stigma, and misinformation among politicians and the public.
