From spiders spinning their webs to the manufacturing of textiles, the formation of fibers from liquids plays an important role in both nature and industry. Yet accurately predicting the properties of such fibers remains a challenge. The fiber is often much thinner than the nozzle from which a polymer or solution is extruded. Factors such as temperature, flow conditions and chemical reactions ultimately determine a fiber’s thickness and strength.
In some materials, physical properties don’t emerge from their individual particles, but from the collective behavior of their quantum spins. Now, researchers led by Pengcheng Dai at Rice University in the U.S. have discovered that in one compound containing the rare-earth element ytterbium, these spins can behave much like the molecules in a liquid crystal: favoring a certain direction without lining up to create magnetism on larger scales.
Former Lawrence Police officer Stuart Bishop is being held on a requested charge of felony intimidation for allegedly sending “targeted,” threatening messages to current officers
Astronomers have detected and traced the most distant fast radio burst ever recorded, a powerful flash of radio waves that traveled for more than 10 billion years across the cosmos before reaching Earth.
As Cambridge Police officers instructed a man to exit his vehicle, he reached under his seat, pulled out a handgun and pointed it at an officer
“Serve the people of this state. That’s the ultimate goal. Truly yours, the California Highway Patrol!” Officer Anthony Talavera rapped during a TV news appearance
Using data from the DESI Legacy Imaging Surveys, with help from artificial intelligence, an international team of scientists has discovered 70 new gravitational lenses—rare cosmic alignments that act as natural magnifying glasses. The new lenses further expand one of the largest collections of confirmed lenses to date and will allow scientists to study dark matter, galaxy evolution and the structure of the universe.
Human stem cells from Adelaide University’s Center for Cancer Biology have successfully traveled to the edge of space and back as part of a landmark mission for Australian cancer research.
Superconductors, materials that can carry electric current with an electrical resistance of zero, have proved to be promising for the development of various technologies, including medical devices, particle accelerators and quantum computers. Studying these materials could help researchers uncover new physical states that could be useful for specific applications.
Some of the best engineers and inventors are copycats. They look at how the natural world solves complex problems and use those mechanisms as the basis for innovations. But Mother Nature doesn’t always give up her secrets easily.
The European Space Agency–led Solar Orbiter spacecraft has flown through an S-shaped kink known as a “switchback” in the solar wind’s magnetic field. By fingerprinting the elusive particles within the switchback, Solar Orbiter has traced its origin back to the sun’s surface and revealed more about solar magnetism—the unruly instigator of dangerous solar storms.
American scientist Margaret Hamilton, who led development of the computer system used by NASA’s Apollo lunar program, has died at 90, her former employer said Wednesday.
A visualization of a dark moon eclipsing the sun is marked with handwritten notes in this April 6, 2026, screenshot from an Artemis II crew member’s tablet.
Federal authorities on Tuesday arrested Sheikhdoon Abdullahi Mohamud, 18, on one count of obtaining a firearm to carry out an act of terrorism
Francis Halzen, winner of the Nobel Prize in physics, spoke with pride on Wednesday about his early promotion of artificial intelligence in his research on neutrinos.
