The voice of legendary physicist Stephen Hawking is to be broadcast into space after his memorial service on Friday, according to British media outlets.

Kentucky's Attorney General announced on Thursday that the state is suing the pharmacy chain Walgreens for allegedly exacerbating the "man-made" opioid crisis, by playing a dual role in in the supply chain as both the distributor and dispenser.

In a way, all of us are time travelers. If we just pause and close our eyes we can wander back to our first kiss...our first breakup...that grandparent we should have visited...the summer that went on forever. This week, we explore two emotions that pull us into the past: regret and nostalgia. How can we make these feelings work for us, and what can we learn from them?

They are among the 92 countries where there is no national policy that allow dads to take paid time off work to care for their newborns.

According to a data analysis released on Thursday by UNICEF, the U.N. children's agency, almost two-thirds of the world's children under age 1 — nearly 90 million — live in countries where dads are not entitled by law to take paid paternity leave. In these countries, this policy is typically decided by employers.

Looking To History To Combat Wildfires

Jun 14, 2018

As at least half a dozen fires in Colorado force hundreds to evacuate, and have closed a national forest, some residents say they're shocked at how quickly the fire has spread. The speed of wildfires is actually something Colorado ecologists have been studying, and they say history may provide clues on how to slow it down.

The number of people dying by suicide in the United States has risen by about 30 percent in the past two decades. And while the majority of suicide-related deaths today are among boys and men, a study published Thursday by the National Center for Health Statistics finds that the number of girls and women taking their own lives is rising.

Ask just about anybody, and you'll probably hear that a healthy diet is one full of fruits and vegetables, olive oil, nuts and fish — what's called Mediterranean diet. A lot of research has suggested people who eat this way tend to be healthier, but it's been harder to prove whether that is because of the diet or some other factor.

ARI SHAPIRO, HOST:

A giant dust storm on Mars is threatening to end the mission of a NASA rover. The rover called Opportunity depends on solar panels to charge its batteries. Right now, the storm has practically blotted out the sun. NPR's Joe Palca has more.

The World Cup starts on June 14 and runs through July 15. The games are in Russia, which is seven hours ahead of Eastern Time — meaning many of the matches will be held around midday in the U.S. So, how can you watch? We run down the options, online and broadcast:

  • On TV, the games will be on either Fox or Fox Sports 1 – on many days, the channels divide the matches. In Spanish, you can watch on both Telemundo and NBC Universo.

Scientists have completed the most exhaustive assessment of changes in Antarctica's ice sheet to date. And they found that it's melting faster than they thought.

Ice losses totaling 3 trillion tonnes (or more than 3.3 trillion tons) since 1992 have caused global sea levels to rise by 7.6 mm, nearly one third of an inch, according to a study published in Nature on Wednesday.

A massive dust storm on Mars is threatening NASA's Opportunity rover, which has been conducting research on the Red Planet for well over a decade.

Where the rover sits, the dust storm has completely blotted out the sun, depriving Opportunity of solar power and cutting off communications with Earth.

NASA scientists believe the rover has fallen asleep to wait out the storm, and that when the dust storm dies down and sunlight returns, the rover will resume activity.

The state of Massachusetts is taking a new step in the fight against the opioid epidemic, filing a lawsuit against Purdue Pharma that also names the OxyContin maker's executives.
