Since the pandemic started, 38.6 million Americans have filed for unemployment claims, according to new numbers announced Thursday.

That's more than one in five American workers using an unemployment insurance system first established decades ago to serve a very different population.

Call it a sign of the times.

Renewable energy has gotten so cheap that even oil giant Exxon Mobil, which reported $20.8 billion in earnings in 2018, is getting in on the savings.

A few years ago, Jason Carney came across a statistic that took him by surprise.

In its 2015 survey of jobs in the solar industry, the nonprofit Solar Foundation reported that 0.0% of solar workers in the state of Tennessee were black or African American.

That number caught Carney's eye because the Nashville native is African American — and was working there as a solar installer in 2015. In fact, he was starting to design a solar array for his own home in north Nashville. Clearly, there had been an undercount.

In northern Georgia, near the Tennessee line, the city of Dalton made its fame as the carpet capital of the world. These days, a more accurate title would be floor covering capital of the world. It has diversified into hardwood, tile, laminate and other materials.

In a windowless classroom at the John J. Moran medium-security prison in Cranston, R.I., three men sit around a table to share how and when they began using opioids.

For Josh, now 39, it was when he was just 13 years old. "I got grounded for a week in my house, so I grabbed a bundle of heroin and just sat inside and sniffed it all week."

"I started using heroin at 19," says Ray, now 23. "I was shooting it. It was with a group of friends that I was working with, doing roof work."

Facing tremendous need after Hurricane Harvey, Texas has made it easier for out-of-state health care providers to come and help.

As rains pounded Houston on Sunday, Dr. Karen Lu took to Twitter and conveyed both alarm and reassurance: "Roads around @MDAndersonNews impassable. Our on-site ride out team is caring for patients and we are all safe."

In southeastern Texas, about two dozen hospitals remained closed as of midafternoon Wednesday, and several Houston hospitals remain under threat of flooding from nearby reservoirs.

But things are looking up. Some hospitals that had been evacuated have reopened, and others are restoring services they had temporarily suspended. Many never closed at all.

As floodwaters continue to rise in parts of Houston, health workers are trying to keep people safe and well, though that challenge is escalating.

"The first and foremost thing that everybody's concerned about is just getting folks out of harm's way with the flooded waters," says Dr. Umair Shah, Executive Director of Harris County Public Health, whose own home came under mandatory evacuation Tuesday morning.

As health departments in Texas try to assist people with immediate medical needs following Hurricane Harvey, they're also looking to ensure that those affected can get the prescription drugs they need and stay as safe as possible.

"Our best advice is always to avoid floodwater as much as you can," says Chris Van Deusen, a spokesman for the Texas Department of State Health Services. "Of course, people have had to be in the water — they haven't had a choice."

Dan Fabbio was 25 and working on a master's degree in music education when he stopped being able to hear music in stereo. Music no longer felt the same to him.

To get a sense of how severe the opioid crisis is in the U.S., you can look at the number of fatal overdoses — more than 33,000 in 2015, according to the Centers for Disease Control and Prevention. That means, on average, 91 people are dying after overdosing on opioids each day. And for every fatal overdose, there are believed to be roughly 30 nonfatal overdoses.

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.
