Interesting reflection on the collapse of the USSR, from the vantage point of a cosmonaut who returned to a completely different world. After blasting off from Baikonur, Krikalev wouldn’t inhale earthly air for 312 days. In that time, the soft-spoken cosmonaut would watch his country crumble from 200 miles up. Presidents would change. His hometown…
English speakers tend to assume that all the important research is published in English. More than half of the non-English papers observed in this study had no English title, abstract or keywords, making them all but invisible to most scientists doing database searches in English. […] This problem is a two-way street Not only does the…
Ancient cultures from Africa to Asia to the Mediterranean share core myths such as the animal pursued by a hunter who is transformed into a constellation, or a sculptor falling in love with a statute that comes to life, or a clever hunter outwitting a monster who keeps animals in a cave. This Scientific American…
Promoting science and technology education to the exclusion of the humanities may seem like a good idea, but it is deeply misguided. Scientific American has always been an ardent supporter of teaching STEM: science, technology, engineering and mathematics. But studying the interaction of genes or engaging in a graduate-level project to develop software for self-driving…
Fascinating theory. The hard work of raising helpless babies is part of the natural selection process that made us as a species so intelligent. Natural selection favors humans with large brains, because those humans tend to be smarter. This may create evolutionary incentives for babies that are born at an even earlier developmental stage, which…
If movies about space have taught us anything, it’s that no one can hear you scream. If you get lost in space, nobody’s going to find you. Unless you’re a spacecraft with a direct link to NASA. Then, there is hope for you yet. STEREO-B, from the Solar and Terrestrial Relations Observatory mission, went missing on…
Americans are more worried than enthusiastic about using gene editing, brain chip implants and synthetic blood to change human capabilities. Majorities of U.S. adults say they would be “very” or “somewhat” worried about gene editing (68%), brain chips (69%) and synthetic blood (63%), while no more than half say they would be enthusiastic about each…
Now imagine the resources required to simulate the brains of millions or billions of dead people. It’s possible that some future technology will allow for unlimited RAM and we’ll all get free service. The same way we’re arguing about health care now, future activists will chant, “The afterlife is a right, not a privilege!” But…
The Selfish Gene is a brilliant phrase. It’s also accurate, so long as you realise that “selfish” doesn’t mean selfish, “gene” doesn’t mean gene, and the definite article is a bit of an abstraction. But taken as the literal truth, it’s about as much use as “In the beginning was the word”. Given Dawkins’s hostility…
The 96-year-old inventor of the eponymous anti-choking procedure had never actually used it to save a life — until the woman sitting next to him at a retirement facility got a bite of hamburger lodged in her throat. When he heard that a resident was choking, Perry Gaines, maître d’ for the Deupree House dining room,…
The brain-as-computer is a powerful meme. It’s no more accurate than metaphors inspired by fluid dynamics or automata, which were cutting-edge technology in their time, says Robert Epstein. The invention of hydraulic engineering in the 3rd century BCE led to the popularity of a hydraulic model of human intelligence, the idea that the flow of…
This sounds like the plot of a Young Indiana Jones episode, or maybe Johnny Quest. William Gadoury is a 15-year-old student from Saint-Jean-de-Matha in Lanaudière, Quebec. The precocious teen has been fascinated by all things Mayan for several years, devouring any information he could find on the topic. During his research, Gadoury examined 22 Mayan…
Interesting essay challenging the notion that medical difference equals pathology. With Children of a Lesser God, The Curious Incident of the Dog in the Nighttime, “Flowers for Algernon,” “Cathedral,” The Glass Menagerie, The Miracle Worker, and The Sound and the Fury, I can see putting together a special topics literature course on pathology and pathos…
I’m somewhat interested in the topic, but I’m actually posting about this because my freshman writing students are now in the process of gathering sources for their research paper. I have to train them to ignore reader-friendly science journalism like this, and instead engage directly with the academic source this reporter is summarizing. That’s a…
The University of Maryland on Friday disavowed its study saying a company’s chocolate milk could help athletes recover from concussions, citing a range of problems uncovered by an internal investigation. The university said it is reviewing its internal research procedures as a result, and deleting press releases about Fifth Quarter’s milk from its website. It…
On Jan. 27, 1986, the former engineer for shuttle contractor Morton Thiokol had joined four colleagues in trying to keep Challenger grounded. They argued for hours that the launch the next morning would be the coldest ever. Freezing temperatures, their data showed, stiffened rubber O-rings that keep burning rocket fuel from leaking out of the…
The Challenger made it through the spectacular eruption of its external fuel tank with its cabin more or less intact. Rather than being carried to Heaven in an instant, the crippled vessel kept sailing upward for another three miles before its momentum gave out, then plunged 12 miles to the ocean. The crew was, in…
I was a high school senior, watching on the TV in the library. The Space Shuttle Challenger disaster occurred on January 28, 1986, when the NASA Space Shuttle orbiter Challenger (OV-099) (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members, which included five NASA astronauts and…
I clicked for the topic, but it was the writing that captured me. The first impulse sets a secret timer, and what the fly does in the next 20 seconds will determine its fate. If it avoids the hairs, it will live. If it bumps a second one, it sets off another electrical impulse, which raises…
The idea that early eating is essential makes perfect sense for farm laborers and small children. Whether it matters for normal, sedentary adults is a different question. Many—if not most—studies demonstrating that breakfast eaters are healthier and manage weight better than non-breakfast eaters were sponsored by Kellogg or other breakfast cereal companies whose businesses depend on…
