Asteroid Rate Jumped in Solar System’s Past
An analysis of lunar craters has found that we’ve been living in a relatively violent period in cosmic history.
Missing Galaxies? Now There’s Too Many
Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem, suggesting that our understanding of how galaxies get built is incomplete.
Why the Best Place to Find Dark Matter May Be in a Rock
Dark matter may occasionally interact with minerals in the earth, leaving telltale tracks that physicists hope to decipher.
How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
Milestone Experiment Proves Quantum Communication Really Is Faster
In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
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.
