Phys.org / DNA programs a cell-free material to build its own motors and move
Researchers have created a material that manufactures the proteins responsible for cell movement, without needing intact living cells. By embedding cell-free gene expression into a thin sheet of protein filaments, they were ...
Phys.org / Experiment shows when quantum 'cat' states stop bouncing back
Quantum systems can occupy superpositions, quantum states that combine different possibilities. For instance, a microwave field can be prepared in a superposition of an empty state and a state that contains microwave light.
Phys.org / ALMA spots 'dragon egg' that may represent the earliest stages of massive star formation
Astronomers identified an exceptionally tiny core that may represent an early stage in the formation of a massive star. Located in an infrared-dark area called Dragon Cloud, the core is nicknamed the "dragon egg." The paper, ...
Phys.org / Sinking Antarctic ice reveals a hidden lake's massive water loss
The Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf was hidden beneath Antarctica's ice, but its drainage left a mark visible from space as a broad depression that deepened by more than 6 meters (20 feet) ...
Phys.org / AI agents can form political camps—and changing their conversation partners does little to soften their views
Give AI agents political positions, ask them to defend their views and persuade one another, and let them decide which contacts to keep. This recent experiment, published in Nature Communications, found that over repeated ...
Phys.org / An ancient virus in chimpanzee DNA switches off a gene that is active in humans
Humans and chimpanzees share almost all their genes. Despite this, our brains have developed in different ways. Researchers at Lund University in Sweden have now shown that a viral pandemic dating back several million years ...
Phys.org / El Niño then and now
El Niño is part of a natural climate pattern that occurs roughly every two to seven years, bringing warmer-than-normal water to parts of the equatorial Pacific. The most recent very strong El Niño events, in 1997–98 and 2015–16, ...
Phys.org / Everyday Mylar turned into a promising insulator for lunar habitats
Establishing a long-term presence on the moon will require solving challenges that are easy to overlook on Earth. Lunar temperatures, for instance, can vary from hundreds of degrees below zero to boiling, making effective ...
Phys.org / Paleolithic human DNA reveals east-west connections across Ice Age Europe
More than 30,000 years ago, people associated with one of Europe's major Paleolithic cultures (the Gravettian) were more interconnected than previously thought. An international research team led by the University of Vienna ...
Phys.org / Black holes spinning near maximum rate could split in two, calculations suggest
Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants ...
Phys.org / Strategic new protections could link 13 Pacific deep-sea reserves into connected network
Protected areas have been set up to shield deep-sea life from the impacts of seabed mining in the Pacific Ocean. However, new research led by scientists at Plymouth Marine Laboratory (PML) and published in Nature Ecology ...
Phys.org / Archimedes screw inspires single-molecule motor powered by electric current
Molecular machines are regarded as the next step in miniaturization. Their models can be found in living cells, where molecular motors convert energy and generate movement. Scientists have been working for decades to artificially ...
