Explanation: Why is this neutron star off-center? Recently a lone neutron star has been found within the debris left over from an old supernova explosion. The "lonely neutron star" in question is the blue dot at the center of the red nebula near the bottom left of E0102-72.3. In the featured image composite, blue represents X-ray light captured by NASA's Chandra Observatory, while red and green represent optical light captured by ESO's Very Large Telescope in Chile and NASA's Hubble Space Telescope in orbit. The displaced position of this neutron star is unexpected since the dense star is thought to be the core of the star that exploded in the supernova and created the outer nebula. It could be that the neutron star in E0102 was pushed away from the nebula's center by the supernova itself, but then it seems odd that the smaller red ring remains centered on the neutron star. Alternatively, the outer nebula could have been expelled during a different scenario -- perhaps even involving another star. Future observations of the nebulas and neutron star appear likely to resolve the situation.

Air Ambulance Surprise | Chair Care For Your Back | Sea Lion Attacks

Almost Every Chair Has One Of Two Problems
Shelby Knowles for NPR
 

Doctor Injured In ATV Crash Gets $56,603 Bill For Air Ambulance Trip

While driving an all-terrain vehicle for the first time, Dr. Naveed Khan, a 35-year-old radiologist, had a terrible accident.

"As soon as I turned to the side where my body weight was, this two-seater vehicle ... just tilted toward the side and toppled," Khan recalled. It landed on his left arm, tearing it open.

Khan fashioned a tourniquet from his jacket to stanch the bleeding, and a friend called 911. The injury was so bad that Khan had to be taken by helicopter to a trauma center more than a hundred miles away.

Despite eight operations to try to save his left forearm, Khan eventually had it amputated to get on with his life.

The air ambulance company charged $56,603 for the emergency trip; Khan’s insurer paid $11,972. Now he’s on the hook for $44,631, NPR’s Alison Kodjak reports in the latest Bill of the Month story done in conjunction with our partners at Kaiser Health News.

Khan was mortified by the cost of the medevac ride and the amount he’s supposed to pay. “It's whatever price they want to set,” he said. “And to put that onto a person who's already been through what I've been through, I hate to say it, but it's cruel."

Can't Get Comfortable In Your Chair? Try This

Almost every chair has one of two problems: It’s either too deep or too soft.

"When a chair is too deep, the backrest is too far away from the edge and you can't put your legs [feet] on the ground without slouching," says Jean Couch of Palo Alto, Calif. When a chairs is too soft, it's almost impossible not to slouch.

But NPR’s Michaeleen Doucleff reports on three ideas for making the best of even a bad seat: Sit on the edge, create a perch and build out the backrest.

Why Did An Octopus-Wielding Sea Lion Slap A Kayaker In The Face?

A sea lion smacks a kayaker with an octopus, and the video capturing the unlikely encounter quickly becomes a viral sensation.

The conflict between man and beasts happened off the coast of New Zealand's South Island, where Taiyo Masuda, Kyle Mulinder and friends were going for a paddle.

NPR Science Desk intern Rachel D. Cohen stretched Shots’ mandate to ask some scientists experienced with sea lions and animal cognition what the suddenly famous sea lion might have been thinking.

“The behavior in that video is pretty normal behavior for a sea lion that is feeding on prey that is too big to swallow whole," says Colleen Reichmuth, a researcher at the University of California, Santa Cruz's Institute of Marine Sciences.

"Frequently people observe sea lions doing new things that we did not know they could do," says Peter Cook, who studies animal cognition at the New College of Florida. "There are always a lot of questions, and we make our best guess. But, yeah, they can surprise you."

Those big, soft chairs are breaking our backs

A young castaway survived 49 days in the Pacific

The 19-year-old had been living aboard a floating hut off Indonesia with supplies meant to last a week when it became unmoored in July. He did not have any way to steer or power the raft and was left to the mercy of the sea.

He was finally rescued when he somehow managed to get his walkie-talkie to a frequency that a passing ship was using.

The cautionary tale of Cornell researcher Brian Wansink

The head of the Food and Brand Lab at Cornell University had become famous for producing pithy, palatable studies that connected people's eating habits with cues from their environment, and his work was often cited by national news outlets, including NPR

But after allegations of research misconduct were made, Cornell reported that he had not kept original data and that the university could no longer vouch for the validity of his studies.

How to keep your spine straight while sitting down

For most of Western history, we sat in chairs that were relatively firm and proportioned for the human body. Then new materials that emerged in the 20th century had designers playing with chairs in ways that ended up hurting our backs.

Don't rush out to replace your chairs. Instead, Jean Couch, who is part of a movement to teach people how to move and sit as our ancestors did, offers three tricks for getting the right alignment.

The son of a KKK grand wizard renounces white nationalism

Derek Black was the heir apparent to his father’s work, which included creating the website Stormfront and re-branding white supremacy. Black grew up giving speeches and hosting a radio show to spread those beliefs. Then he went to college and began to question that point of view.

“I said things that tried to energize racist ideas and get people to be more explicit about it. And then people who listened to that and who believed it, some of them committed horrible, violent acts. And what is my culpability and responsibility for how these things went out into the world and they continue to bounce around in the world, and I can't take them back?”

His "awakening" is the subject of Pulitzer Prize-winning journalist Eli Saslow's new book, Rising Out Of Hatred.

What's next for the Kavanaugh nomination 

If you somehow missed it, Supreme Court nominee Brett Kavanaugh and Christine Blasey Ford, who has accused him of sexually assaulting her while they were in high school, testified Thursday before the Senate Judiciary Committee. NPR’s Ron Elving called Kavanaugh’s defiant testimony “the latest in a list of Capitol Hill norms to be lost in the era of President Trump.”

The next day, the panel voted along party lines to recommend the judge’s nomination to the full Senate, but Republican leaders agreed to a delay to give the FBI one week to investigate the allegations (two other women came forward ahead of the hearing but did not testify before the committee). The White House has agreed to a limited “supplemental investigation.”

The new deadline for a Kavanaugh vote is Oct. 5.

APOD - 55 Nights with Saturn

55 Nights with Saturn

Explanation: For 55 consecutive nights Mediterranean skies were at least partly clear this summer, from the 1st of July to the 24th of August 2018. An exposure from each night was incorporated in this composited telephoto and telescopic image to follow bright planet Saturn as it wandered through the generous evening skies. Through August, the outer planet's seasonal apparent retrograde motion slowed and drifted to the right, framed by a starry background. That brought it near the line-of-sight to the central Milky Way, and the beautiful Lagoon (M8) and Trifid (20) nebulae. Of course Saturn's largest moon Titan was also along for the ride. Swinging around the gas giant in a 16 day long orbit, Titan's resulting wave-like motion is easier to spot when the almost-too-bright Saturn is digitally edited from the scene.

The Light, the Dark, and the Dusty
Image Credit & Copyright: Tasos Liampos

Explanation: This colorful skyscape spans about two full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region's massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 is below and right of center, also known as the Cave Nebula. About 10 light-years across the cosmic cave's bright walls of gas are ionized by ultraviolet light from the hot young stars around it. Dusty blue reflection nebulae, like vdB 155 at upper left, and dense obscuring clouds of dust also abound on the interstellar canvas. Astronomical explorations have revealed other dramatic signs of star formation, including the bright red fleck of Herbig-Haro (HH) 168. Near top center in the frame, the Herbig-Haro object emission is generated by energetic jets from a newborn star.
