These small ermine moths have no hearing organs. Yet their wings produce ultrasound. Here is the researchers' recording, made audible. The secret is a tiny ridged patch on each hindwing. As the wing flexes, those ridges snap through, one after another. Each snap vibrates a thin membrane, making a cl...
ViewThe **300,000-tonne figure was a design-study estimate, not a measured saving from built habitats**. The 1977 study compared a Bernal Sphere, a rotating spherical living area with agriculture in thin toruses outside its shield, against a banded torus, a multi-component toroidal design. Under its rev...
ViewAt four in the afternoon, a light “far above the brightest day” astonished people in Tuam, Ireland, the book reports. The unusual light gradually faded. The book gives no explanation for what caused it. At seven, streamers appeared in a band from west to east, undulating like rippling water across t...

ViewThe Criterion essay describes the film’s intricate miniatures as part of a tactile effects language whose visible seams need not break the illusion. The model edge, supports, and traveler shown here are invented editorial cues to make scale legible, not evidence of the film’s actual miniature setup....
ViewIn *A Hundred Anecdotes of Animals*, a young sow grew so fond of a gamekeeper’s pointer puppies that she played and fed with them. The keeper decided to try training her alongside the dogs. Coaxed farther afield with barley-meal pudding, she reportedly worked the ground like a pointer, stood when s...
ViewTiny homes and backyard reading nooks share a cozy-hut idea: a small space can feel like a sanctuary. 🛖 Try a renter-friendly boundary: let a rug mark one corner as your nook, with a chair nearby. 🪴 Add a throw, a plant or found keepsake, then bring in warm mood light. Let daylight in when you can...
ViewOn STS-49, ground training did not prepare the crew for the orbital task; the shuttle’s Remote Manipulator System was its robotic arm. During the May 10 attempt, Pierre Thuot held a capture bar fitted with a grapple fixture while Bruce Melnick operated the shuttle’s arm. As the crew tried to capture...
ViewMayflies are insects whose young live and grow in water before emerging as adults. In Odd Showers, Sir George Duncan Gibb describes mayflies, which he calls ephemerae, appearing in immense numbers along rivers and streams by the St. Lawrence, perhaps across hundreds of miles.

ViewIn March 1808, red snow reportedly fell for three nights in Carniola and nearby regions. In Carniola, red snow lay over white snow; the layers stayed distinct as they melted, and the red left rose-coloured earth. Gibb proposed volcanic ash, or puzzolana resembling brick dust, as a possible coloring ...
ViewAcross an Alpine glacier, the ice could appear blue, from a faint tinge to a deep hue; the blue was described as especially vivid in clefts where the ice was thawing. Yet a crystal or small piece broken from the mass could look simply white and transparent, or frothy and semi-opaque. The account int...
ViewSalyut 7’s ODU, its main propellant system, needed repair after its oxidizer system was damaged. With no nearby handholds, the crew carried about 40 kilograms of equipment across the station’s hull to reach the worksite. They drove anchor pins into the equipment compartment’s plastic skin to secure ...
ViewIn his 1865 account, Frank Cowan calls cochineal a valuable dye material obtained from an insect found on the Mexican nopal, or tuna. He reports that Spaniards encountered it around 1518 and that, in 1523, the Spanish ministry ordered Cortés to encourage its production; Cowan says it subsequently be...

Loudon recounts an occasion when the French coast appeared from Hastings, raised above the sea for nearly an hour before gradually sinking from view. In the Fata Morgana described in the account, a spectator facing a calm sea s...
