Lectures for a New Year: A Brain Scientist Studies Her Own Stroke

Dr. Jill Bolte Taylor is a neuroanatomist (or "brain scientist") from Indiana. In 1996 she experienced a major stroke, out of the blue, at age 37. As a scientist deeply involved with brain function, she was ideally situated to understand the stroke as it happened (as much as anyone can during a frickin' stroke), and later to draw meaningful lessons from what happened. That stroke is the topic of this twenty-minute lecture.

Bolte Taylor's "Stroke of Insight" is the second most-watched TED Talk of all time, with many millions of views across various channels. It's a curious lecture, as my first reaction to it was, frankly, "Boy, this lady seems to be using some hippie-dippy language in describing the people in the room." (Lots of "energy" and "connection" and such.) It was only after I'd listened to the entire talk that I understood her point: the brain's hemispheres have different ways of viewing the world; she chooses to inhabit the hemisphere that uses language that I perceived as hippie-dippy. This is actually really profound and emotional -- watch the talk to witness this arc for yourself.

Topics: the brain's hemispheres as parallel and serial processors, the separate experiences of those two brains, what happens when one begins to malfunction, and what this means about our individual experience of the world.

For: anyone interested in the brain, cognition, and how we think about our world. Warning: a real human brain is shown and handled onstage, as an explanatory prop. This may be gross to some lots of people. It's fairly brief.

Further Reading

Although I haven't read it, Bolte Taylor wrote a book about her experience, entitled My Stroke of Insight: A Brain Scientist's Personal Journey. She also has an extensive website which reveals that, among other things, she endorses Taylor acoustic guitars. Nice!

Transcript

TED Talks have great transcripts; on the TED site there's an interactive transcript (upper right part of the page) and there are subtitles available in 42 languages on the TED site. You can even download high-quality versions of the video with or without subtitles.

Neil deGrasse Tyson Recruits George R.R. Martin to Work on His New Video Game

George R.R. Martin has been keeping busy with the latest installment of his Song of Ice and Fire series, but that doesn’t mean he has no time for side projects. As The Daily Beast reports, the fantasy author is taking a departure from novel-writing to work on a video game helmed by Neil deGrasse Tyson.

DeGrasse Tyson’s game, titled Space Odyssey, is currently seeking funding on Kickstarter. He envisions an interactive, desktop experience that will allow players to create and explore their own planets while learning about physics at the same time. To do this correctly, he and his team are working with some of the brightest minds in science like Bill Nye, former NASA astronaut Mike Massimino, and astrophysicist Charles Liu. The list of collaborators also includes a few unexpected names—like Martin, the man who gave us Game of Thrones.

Though Martin has more experience writing about dragons in Westeros than robots in outer space, deGrasse Tyson believes his world-building skills will be essential to the project. “For me [with] Game of Thrones ... I like that they’re creating a world that needs to be self-consistent,” deGrasse Tyson told The Daily Beast. “Create any world you want, just make it self-consistent, and base it on something accessible. I’m a big fan of Mark Twain’s quote: ‘First get your facts straight. Then distort them at your leisure.’”

Other giants from the worlds of science fiction and fantasy, including Neil Gaiman and Len Wein (co-creator of Marvel's Wolverine character), have signed on to help with that same part of the process. The campaign for Space Odyssey has until Saturday, July 29 to reach its $314,159 funding goal—of which it has already raised more than $278,000. If the video game gets completed, you can expect it to be the nerdiest Neil deGrasse Tyson project since his audiobook with LeVar Burton.

Flying Telescopes Will Watch the Total Solar Eclipse from the Air

If you've ever stood on the tips of your toes to reach something on a high shelf, you get it: Sometimes a little extra height makes all the difference. Although in this case, we're talking miles, not inches, as scientists are sending telescopes up on airplanes to monitor conditions on the Sun and Mercury during the upcoming total eclipse.

Weather permitting, the Great American Eclipse (as some are calling it) will be at least partially visible from anywhere in the continental U.S. on August 21. It will be the first time an eclipse has been so widely visible in the U.S. since 1918 and represents an incredible opportunity not only for amateur sky-watchers but also for scientists from coast to coast.

But why settle for gawking from the ground when there's an even better view up in the sky?

Scientists at the Southwest Research Institute (SwRI) have announced plans to mount monitoring equipment on NASA research planes. The telescopes, which contain super-sensitive, high-speed, and infrared cameras, will rise 50,000 feet (about 9.5 miles) above the Earth's surface to sneak a very special peek at the goings-on in our Sun and its nearest planetary buddy.

Gaining altitude will not only bring the instruments closer to their targets but should also help them avoid the meteorological chaos down below.

"Being above the weather guarantees perfect observing conditions, while being above more than 90 percent of Earth's atmosphere gives us much better image quality than on the ground," SwRI co-investigator Constantine Tsang said in a statement. "This mobile platform also allows us to chase the eclipse shadow, giving us over seven minutes of totality between the two planes, compared to just two minutes and 40 seconds for a stationary observer on the ground."

The darkness of that shadow will blot out much of the Sun's overpowering daily brightness, giving researchers a glimpse at rarely seen solar emissions.

"By looking for high-speed motion in the solar corona, we hope to understand what makes it so hot," senior investigator Amir Caspi said. "It's millions of degrees Celsius—hundreds of times hotter than the visible surface below. In addition, the corona is one of the major sources of electromagnetic storms here at Earth. These phenomena damage satellites, cause power grid blackouts, and disrupt communication and GPS signals, so it's important to better understand them."

The temporary blackout will also create fine conditions for peeping at Mercury's night side. Tsang says, "How the temperature changes across the surface gives us information about the thermophysical properties of Mercury's soil, down to depths of about a few centimeters—something that has never been measured before."
