The world's oceans are rising. Over the past century, they're up an average of about eight inches. But the seas are rising more in some places than others. And scientists are now finding that how much sea level rises in, say, New York City, has a lot to do with exactly where the ice is melting.

A warming climate is melting a lot of glaciers and ice sheets on land. That means more water rolling down into the oceans.

But the oceans are not like a bathtub. The water doesn't rise uniformly.

Democrats' success in this month's elections was bigger than expected, and was fueled in part by strong opposition to President Trump. In the last few weeks, there's been a lot of chatter about whether that means a big, blue wave is forming off the political coast that could potentially crash into the 2018 midterm elections.

NASA has big hopes for virtual reality technology. The agency is developing a suite of virtual reality environments at Goddard Spaceflight Center in Maryland, that could be used for everything from geological research to repairing orbiting satellites.

One displays fiery ejections from the Sun. In another, scientists can watch magnetic fields pulse around the earth. A virtual rendering of an ancient lava tube in Idaho makes scientists feel like they're standing at the bottom of an actual cave.

When President Trump declared the opioid epidemic a public health emergency, it came with a regulatory change intended to make it easier for people to get care. Doctors are now allowed to prescribe addiction medicine virtually, without ever seeing the patient in person.

In Indiana, this kind of virtual visit has been legal since early 2017. So I called about a dozen addiction specialists in Indiana to find out how it was going. But no one had heard of doctors using telemedicine for opioid addiction treatment until I ran across Dr. Jay Joshi.
