A light-controlled 'muscle' could give synthetic cells a new way to move
Engineers interested in creating artificial cells to deliver drugs to unhealthy parts of the body face a key challenge: for a cell-like system to move, change shape, or divide, it needs a way to generate force on command.
Archaeologists have discovered 12,000‑year‑old dice. Here's what they reveal about the history of play
Humans have always been playful. But for much of our history, play has left little trace. Unlike tools or bones, games rarely preserve and the fleeting pleasures they produce are even harder to recover.
Wafer-scale 2D magnetic films emerge thanks to a new low-defect growth technique
In a major advance, researchers at the Indian Institute of Science (IISc) have devised a method to grow high-quality 2D magnetic materials (2D-MMs) over centimeter-scale wafers. Earlier approaches in the field were limited to growing micrometer-sized flakes. This advance paves
'Protected' seagrass meadows aren't necessarily healthy, because pollution doesn't stop at the shoreline
I spent last summer wading through seagrass meadows across Northern Ireland, from the sheltered waters of Strangford Lough to the exposed coast at Waterfoot Bay. I was collecting seagrass leaves and testing them for nitrogen pollution. Every meadow I visited sits inside a
Sulfur-rich Mercury magmas behave differently than Earth's do
Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It is also reduced, a chemical state in which the
Moroccan dinosaur's fearsome tail spikes evolved much earlier than we thought—new discovery
In the heart of the Middle Atlas Mountains in central Morocco, a global team of paleontologists and geologists has discovered new remains of a very unusual dinosaur. It belonged to the group called ankylosaurs, plant eaters whose bodies were covered in bony plates.
How tiny voids could make fusion targets more stable under powerful shockwaves
Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it
Why anatomy's naughtiest mnemonics work so well
Some lovers try positions that they can't handle—I'm referring to the bones of the wrist, of course. The phrase is a classic mnemonic used to remember the eight carpal (wrist) bones—scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate and hamate—whose initials
These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star
Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering two important clues about their nature. A paper
Theoretical models of supernova chemistry overhauled after X-ray data from Perseus Cluster reveal key discrepancies
The Perseus Cluster is a massive galaxy cluster located in the constellation Perseus. It is one of the largest structures in the observable universe, comprising more than a thousand galaxies—equivalent to roughly a thousand trillion times the mass of the sun. Hot gases within
Your local fishing hole is getting browner, changing which fish species thrive and which ones struggle
The lakes, streams, and ponds you've visited for years are likely looking more brown than they used to. And people who are fishing those waters are likely catching different species and sizes of fish than in the past.
Support fundamental research, prize-winning mathematician urges
French mathematician Frank Merle, who won a prestigious Breakthrough Prize on Saturday, told AFP that fundamental research must be supported because it is a "foundation stone" for the future.
Hollow-sphere catalyst enables greener production of 99% pure propene at room temperature
