Barbie can do it all. In Greta Gerwig’s 2023 film, she appears as a US president, a Nobel Prize winning physicist, a Supreme Court Justice and even a mermaid. The movie reflects the many roles the doll has had over the decades. One of her most famous is as a space explorer. In the 1960s, Astronaut Barbie was transporting children on space adventures even before Nasa’s own astronauts had taken their first steps on the Moon and 13 years before Nasa began accepting female astronauts into their programme.
Now Barbie has been helping space exploration for real. In recent experiments, scientists used the dolls to test methods of removing Moon dust from spacesuits. Wearing a tailor-made spacesuit, Barbie was coated in volcanic ash by a team from Washington State University and sprayed with liquid nitrogen. They found this technique is more effective than previous cleaning methods.
Why is lunar dust a problem? Moon dust is “ubiquitous, abrasive and electrically charged”, according to Ian Wells, a graduate researcher at Washington State University, who was speaking to the BBC World Service programme Unexpected Elements. These “annoyingly clingy” microscopic particles statically stick to the spacesuits of astronauts and are difficult to clean off. During the Apollo missions, astronauts were unable to remove the dust using standard brushes, resulting in damage to the seals on their spacesuits.

At first blush, the journalist Michael Finkel’s captivating new book, “
I am an accidental birder. While I never used to pay much attention to the birds outside my window, even being a bit afraid of them when I was a child, I have always loved making lists. Ranking operas and opera houses, categorising favourite books and beautiful libraries – not to mention decades of creating ‘Top Ten’ lists of hikes, drives, national parks, hotels, and bottles of wine. My birding hobby grew out of this predilection. Specifically, out of my penchant for writing down the birds I found in the paintings by the Old Masters.
One recalls the days when sympathy was not reduced to a series of yellow crying faces – when people had more time to be human and condolences were not something to be fired off before scrolling on to the next Facebook post.
In 1973 rookie reporter Kevin McKiernan smuggled himself onto the Pine Ridge Sioux Reservation in the trunk of a car, hoping to cover the takeover of Wounded Knee, South Dakota. Embedded with activists of the American Indian Movement (AIM)—who clamored for control of their communities and an end to slum conditions, McKiernan filmed their conflicts with Tribal Chair Richard (“Dickie”) Wilson, his armed supporters who called themselves Guardians of Oglala Nation (GOONs), and the government agents backing them. Despite a media blackout, McKiernan sat in on AIM negotiations with the Nixon administration, earning on-camera glares from negotiator Kent Frizzell. As a settlement was hammered out between the groups, McKiernan buried his film in a hole and smuggled himself out of the encampment. Arrests followed, his included. Six weeks later, he returned to Wounded Knee to recover his footage.
I met Gordon in Phnom Penh a year ago. He had agreed to take me and Ashish Dhakal, a journalist and repatriation activist from Nepal, to Koh Ker and Angkor. First, though, I spent nearly a week at the National Museum of Cambodia. It opened in 1920, designed by George Groslier, to hold the artefacts that archaeologists in French Indochina weren’t shipping back to Paris. He enlarged the architectural forms of Cambodian Buddhist temples to create a building that hadn’t previously been needed in a region where sacred artworks generally remained in place.
Multiple sclerosis presents far more variously than most other illnesses; for that reason, it has been called “the great imitator.” Some of the conditions it can resemble are minor, and others are major. If you have ever Googled a random tingling or twinge or eyebrow twitch, you have probably spent at least one evening convinced that you have M.S. On the other hand, M.S. patients often think for a while that they don’t have much going on. One person’s first symptom might be numbness. A different patient might experience weakness. Or an unexplained fall, or fatigue, or difficulty urinating or walking. In the United States, the incidence is around three people in a thousand, which is either rare or common, depending on the emotional heft you ascribe to a third of one per cent of the population.
Filmmakers like Quentin Tarantino, Martin Scorsese, and Christopher Nolan are known for being beloved by film bros around the world. If Hollywood makes “chick flicks” for women, these directors win prizes for providing what everyone believes to be the opposite thing—a type of film that, interestingly, doesn’t have a catchy, degrading name. (Gloria Steinem once
Neuroscientists, educators and psychologists like Kathy Hirsh-Pasek know that play is as an essential ingredient in the lives of adults as well as children. A weighty and growing body of evidence—spanning evolutionary biology, neuroscience and developmental psychology—has in recent years confirmed the centrality of play to human life. Not only is it a crucial part of childhood development and learning but it is also a means for young and old alike to connect with others and a potent way of supercharging creativity and engagement. Play is so fundamental that neglecting it poses a significant health risk.
For most ordinary people, it is assumed that “we” exist somewhere within the skull, and this self is free to make decisions. This self is the “captain” of the body, controlling our behaviors and making our life choices. The problem is that neither this inner self nor free will exists the way most think that it does. Research conclusively demonstrates that these are just stories that we humans make up. Michael Gazzaniga’s groundbreaking research eventually concludes that the self is just a fiction created by the brain. Humans make up such stories, believe in them, and rarely question their validity. However, this isn’t the bad news it may appear to be. It is good news, but it will take a while to grasp.
