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.
Like a hit-and-run driver who races from the scene of a crash, the interstellar guest known as 'Oumuamua has bolted out of the solar system, leaving confusion in its wake: it behaves neither like an asteroid or a comet.
A visual prank exposes an Achilles' heel of computer vision systems: Unlike humans, they can't do a double take.
Astronomers have known where the universe’s missing matter has been hiding for the past 20 years. So why did it take so long to find it?
Computer vision researchers have uncovered a world of visual signals hiding in our midst, including subtle motions that betray what's being said and faint images of what's around a corner.
Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.
Studying the structure of existing friendships in your community can help you forge the best connections when forming a new circle of friends.
The nearest neighbor problem asks where a new point fits in to an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way.
Black holes occasionally reveal themselves when passing stars get ripped apart by their gravity. These tidal disruption events have created a new way for astronomers to map the hidden cosmos.
New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called "octonions."
Water-bearing minerals reveal that Earth's mantle could hold more water than all its oceans. Researchers now ask: Where did it all come from?
A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain's modeled expectations.
Many astronomers remain convinced that a once-in-a-generation discovery is in the offing — one that would rewrite textbooks down to the elementary school level. They just can't find it.
With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.
Recent experiments have put relatively large objects into quantum states, illuminating the processes by which the ordinary world emerges out of the quantum one.
Computer scientists have been searching for years for a type of problem that a quantum computer can solve but that any possible future classical computer cannot. Now they've found one.
If a forest is burning and we don't know what's responsible, does it have a cause?
In an era when untestable ideas such as the multiverse hold sway, Michela Massimi defends science from those who think it hopelessly unmoored from physical reality.
A technique based on genetic bar codes can easily map the connections of individual brain cells in unprecedented numbers. Unexpected complexity in the visual system is only the first secret it has revealed.
The mathematicians Günter Ziegler and Martin Aigner have spent the past 20 years collecting some of the most beautiful proofs in mathematics.
