From the burning of wood to the action of medicines, the properties and behavior of matter are governed by the way chemical elements bond with one another. For many of the 118 known elements, the intricate electronic structures of the atoms that are responsible for chemical bonding are well understood. But for the superheavy elements […]
Author: Rohini Subrahmanyam is a PhD biologist turned science journalist. Insects that tuck away wings; a protist with an accordion-like neck — studying these clever creases may inspire foldable structures for drones As the microscopic, tear-shaped Lacrymaria olor swims around hunting for food, it does something remarkable: In a blink, the tiny protist extends its […]
Non-destructive testing allows engineers to evaluate the integrity of structures such as pipelines, tanks, bridges, and machinery without dismantling them. Conventional approaches rely on loudspeakers, lasers, or electric sparks. While effective, these systems can be difficult or dangerous to use in flammable or confined areas and require considerable power to function effectively. Now, a new […]
A rare North American bumble bee may have been on a path toward extinction long before modern human impacts, suggesting that its long-term genetic vulnerability made it especially fragile and less able to cope with both past and current environmental stresses. The study focused on the Franklin bumble bee, once found only in parts of […]
Deep inside caves, water dripping from the ceiling creates one of nature’s most iconic formations: stalagmites. These pillars of calcite, ranging from centimetres to many meters in height, rise from the cave floor as drip after drip of mineral-rich water deposits a tiny layer of stone. Beyond their beauty—echoed in fanciful nicknames like the “Minaret” […]
When astronauts returned from NASA’s final Apollo moon mission in 1972, some of the samples they collected were sealed and carefully stored away in the hope that future researchers using advanced equipment might analyze them and make new discoveries. Now, researchers report a sulphuric surprise in rock samples taken from the moon’s Taurus Littrow region […]
One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 qubits (quantum bits) could simultaneously store more information than the number of particles in the known universe. Now process this: Harvard scientists just unveiled a system that was 10 times bigger and the first quantum machine able to operate continuously without […]
Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]

A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the […]
Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that are in your phone display, to create such a clock—or, at least, as close as humans can […]
