[:es]Scientists Learn the Ropes on Tying Molecular Knots[:]
[:es]As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible. [:]

[:es]The (Imaginary) Numbers at the Edge of Reality[:]
[:es]Odd enough to potentially model the strangeness of the physical world, complex numbers with “imaginary” components are rooted in the familiar.[:]

[:es]A Proof About Where Symmetries Can’t Exist[:]
[:es]In a major mathematical achievement, a small team of researchers has proven Zimmer’s conjecture.[:]

[:es]Why the Many-Worlds Interpretation Has Many Problems[:]
[:es]The idea that the universe splits into multiple realities with every measurement has become an increasingly popular proposed solution to the mysteries of quantum mechanics. But this “many-worlds interpretation” is incoherent, Philip Ball argues in this adapted excerpt from his new book Beyond Weird.[:]

[:es]Famous Experiment Dooms Alternative to Quantum Weirdness[:]
[:es]Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists a single, concrete reality.[:]

[:es]Interstellar Visitor Found to Be Unlike a Comet or an Asteroid[:]
[:es]The mystery of ’Oumuamua, the first interstellar object ever observed, continues to deepen. A new analysis argues that if it were a comet, it would have broken apart as it passed near the sun.[:]

[:es]Planets Found to Be Larger Than the Disks They Come From[:]
[:es]Like a car that’s twice as heavy as the steel that went into it, exoplanets are far more massive than the material that they’re built out of. The new finding is challenging established theories of how planets come to be. 3 [:]
