Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding puzzle in soft-matter physics.

Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding puzzle in soft-matter physics.
A new computational approach developed at the University of Chicago promises to shed light on some of the world’s most puzzling materials—from high-temperature superconductors to solar cell semiconductors—by uniting two long-divided scientific perspectives.
A new study from a research team at the Center for Wireless Communications Network and Systems (CWC-NS) at the University of Oulu has introduced an approach using near-infrared (NIR) light beyond light therapy to facilitate simultaneous wireless power transfer and communication to electronic implantable medical devices (IMDs). Previously, the research team demonstrated that NIR light for wireless communication is feasible, and now the team made progress by involving wireless charging capabilities using the same light.
The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids that make LCD screens shine?
Scientists have discovered a way to efficiently transfer electrical current through specific materials at room temperature, a finding that could revolutionize superconductivity and reshape energy preservation and generation.
One of the suspects created a detailed plan to bomb five or more companies in the attack; two of the suspects had also planned a bombing attack on ICE agents for 2026
A “House of Cards” is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable. It’s also the term Sarah Thiele, originally a Ph.D. student at the University of British Columbia, and now at Princeton, and her co-authors used to describe our current satellite mega-constellation system in a new paper available in pre-print on arXiv.
When NASA scientists opened the sample return canister from the OSIRIS-REx asteroid sample mission in late 2023, they found something astonishing.
The European Space Agency’s X-ray space observatory XMM-Newton observed interstellar comet 3I/ATLAS on 3 December for around 20 hours. During that time, the comet was about 282–285 million km from the spacecraft.
NASA’s Nancy Grace Roman Space Telescope team has released detailed plans for a major survey that will reveal our home galaxy, the Milky Way, in unprecedented detail. In one month of observations spread across two years, the survey will unveil tens of billions of stars and explore previously uncharted structures.
Omega Centauri dominates the southern sky as the Milky Way’s largest and brightest globular cluster, a dense sphere containing roughly 10 million stars. Earlier this year, astronomers found evidence that an intermediate mass black hole hides within the cluster’s core, revealed by seven stars moving far too quickly to remain bound unless something massive holds them gravitationally. Now, researchers have searched for the black hole itself using radio telescopes, and their discovery is what they didn’t find.
By partnering with artificial intelligence (AI), a researcher at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has solved a long-standing physics problem and uncovered the mathematical trickery that underlies the generalization of recently discovered, extremely surprising new states of matter. The work exemplifies the paradigm shift that is taking place in research, as scientists learn to see AI as a valuable asset in advancing knowledge and discovery.
Oklahoma City Police Department officers tased the man twice and deployed a less-lethal impact round before he charged at them, prompting the shooting
The report alleges Chief Pamela Smith compelled commanders to reclassify crimes and disciplined those who did not comply, creating a hostile work environment
A stray comet from another star swings past Earth this week in one last hurrah before racing back toward interstellar space.
