In the Universe of Equations, Virtually All Are Prime
Equations, like numbers, cannot always be split into simpler elements. Researchers have now proved that such “prime” equations become ubiquitous as equations grow larger.
New Quantum Paradox Clarifies Where Our Views of Reality Go Wrong
A thought experiment has shaken up the world of quantum foundations, forcing physicists to clarify how various quantum interpretations (such as many-worlds and the Copenhagen interpretation) abandon seemingly sensible assumptions about reality.
A Universal Law for the ‘Blood of the Earth’
Simple physical principles can be used to describe how rivers grow everywhere from Florida to Mars.
‘Lava-Lamp’ Proteins May Help Cells Cheat Death
With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.
Galactic Beacons Get Snuffed Out in a Cosmic Eyeblink
Quasars powered by supermassive black holes have been unexpectedly vanishing. Scientists have started to figure out why.
Universal Quantum Phenomenon Found in Strange Metals
Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.
How Holography Could Help Solve Quantum Gravity
In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.
In the Nucleus, Genes’ Activity Might Depend on Their Location
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
Scientists Learn the Ropes on Tying Molecular Knots
As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible.
