Different areas of the brain do different things. The ventral striatum — located deep inside in the brain — plays roles in mood, addiction and learning.

Upwelling brings cold water from the depths of the ocean to the surface. Those cold waters are rich in nutrients, which helps life thrive. Here, areas of upwelling in the ocean highlighted in red.

Taste good? Senses inform the brain — but don’t tell everyone the same thing

What gives all of these foods a different flavor? For starters, each produces a different combination of tastes — information that the brain will sort through as it decides whether it likes a food (or doesn’t).

Electricity sensor harnesses a shark's secret weapon

In this artist’s illustration, gold nanoparticles (bright blue) covered in tiny hairs (shown in purple) surround a virus and attach to it. As more hairs attach, they squeeze the soft surface of the virus to find places to stick. That squeezing builds enough pressure to squash the virus.

Wildfires worsen extreme air pollution in U.S. northwest

The 2018 Carr fire in northern California, seen here outside Redding, threw pollutants into the air for weeks, beginning July 23. The state reported that air quality was “unhealthy” throughout the region affected by this intense fire. One of the biggest in state history, this fire eventually burned more than 175,000 acres and destroyed more than 1,077 homes.
