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.
The (Imaginary) Numbers at the Edge of Reality
Odd enough to potentially model the strangeness of the physical world, complex numbers with “imaginary” components are rooted in the familiar.
A Proof About Where Symmetries Can’t Exist
In a major mathematical achievement, a small team of researchers has proven Zimmer’s conjecture.
Why the Many-Worlds Interpretation Has Many Problems
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.
Famous Experiment Dooms Alternative to Quantum Weirdness
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.
Interstellar Visitor Found to Be Unlike a Comet or an Asteroid
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.
Planets Found to Be Larger Than the Disks They Come From
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.
Unexpected Diversity Found in 16 New Lab Mouse Genomes
The availability of new genomes for 16 diverse strains of laboratory mice will help accelerate research into the genetic underpinnings of human traits and diseases.
