Researchers at the University of Twente and Utrecht University have packed rigid, rod-shaped particles into soft lipid containers the size of a living cell and watched the container and its contents reshape each other. The vesicle’s form determines how the rods line up; the tightly packed rods, in turn, bend the container into new shapes. This provides a minimal model for how physical coupling between a soft boundary and internal filaments can help cellular structures organize from within. The paper is published in the Proceedings of the National Academy of Sciences.
As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into nuclear fusion research. The hope is that fusion may ultimately provide a virtually limitless source of clean energy.
Physicists have long suspected that a peculiar quantum state lurks inside a class of materials known as kagome metals, but proving its existence has been elusive. Now, a team led by Yeongkwan Kim at the Korea Advanced Institute of Science and Technology has performed experiments on a kagome metal that provide the strongest evidence yet for this exotic state.
The Supreme Court declined to review a decision by an appeals court, which ruled a jury could decide whether Toni McBride’s final two shots constituted an excessive use of force
At the Space Symposium’s first UAP panel, David Grusch said the US government is aware of several kinds of non-human intelligence, and predicted disclosure will escalate within 90 days. The post David Grusch Told a Space Conference the US Knows of Several Kinds of Non-Human Intelligence. appeared first on Infinity Explorers. Dr. Richard Flotron was charged with two counts of forgery and terminated from his position as Southeast Missouri State University Campus Police chief
Two LAPD officers responded to the scene after reports of screaming; a large Saint Bernard doodle exited the home and ran toward an officer, who then fired shots
Researchers are constantly sifting through new spectral data gathered by powerful telescopes, like the James Webb Space Telescope (JWST). Most of the time, when they identify spectral features—specific absorption or emission lines from different types of light gathered from a planet, moon or star—these features are known to be caused by certain atoms or molecules. For example, the emission line at 426.7 nanometers is known to come from singly ionized carbon, representing a specific atomic transition between energy states of a carbon ion.
An interstellar comet that blazed past the sun last year could be nearly three times older than our solar system and is unlike anything ever seen before in our cosmic backyard, astronomers said Monday.
Astronomers have discovered a “remarkable” bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published today in Monthly Notices of the Royal Astronomical Society: Letters, has a “highly unusual” and asymmetric structure unlike those seen in standard radio galaxies.
Microorganisms from our planet could survive on celestial bodies where water is present, such as Mars. That is the conclusion of Ph.D. candidate Tommaso Zaccaria after experiments with simulated space conditions. Our immune system reacts less effectively to pathogens that have undergone such a simulated space journey. According to his supervisors, his dissertation provides extraterrestrial insights that are also useful on Earth.
Ask a child to draw some poo, and the shape will invariably be the same: a coil, broad at the base and pointy at the top, similar to a spiral swirl of soft-serve ice cream. In fact, the often-used poo emoji has this exact shape, as do most actual mounds of feces found in nature. Exceptions occur, though, particularly in the feces of some worms that extrude their excrement “upside down” from the ground. As it turns out, there is remarkable physics behind these differences in poo shapes.
Our body contains an intricate system of tiny vessels through which blood, water and other molecules flow. When the size of the pipes shrinks to the nanoscale, where only a few molecules can fit side by side, the classical laws of physics governing the behavior of water are influenced by the atomic structure of the walls. “It’s not that classical hydrodynamics breaks down, but rather that it gets mixed with the condensed matter physics of the solid walls,” says Nikita Kavokine, tenure-track assistant professor and leader of the EPFL Quantum Plumbing Lab.
The U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has reached a key early milestone in developing radiofrequency control systems for the Electron-Ion Collider (EIC)—a next-generation research facility that will collide electrons with ions to reveal how the building blocks of matter are held together.
