Scientists are one step closer to error-correcting quantum computers
Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have…

These colorful butterflies were created using transparent ink
You’ve heard of disappearing ink. Now get ready for suddenly appearing ink. Using a clear liquid, researchers can print a full rainbow of colors on…
Whirling maple seeds inspired these tiny flying sensors
Like helicoptering maple seeds, tiny new fliers whirl gracefully as they glide. The miniature aircraft, which can be made as small as a grain of…
One of nature’s key constants is much larger in a quantum material
A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in…
New ‘vortex beams’ of atoms and molecules are the first of their kind
Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Scientists already knew how to dish up spiraling beams of…
Physicists caught protons ‘surfing’ on shock waves
Protons can surf some truly gnarly waves. A new experiment suggests that the subatomic particles can be accelerated by a process akin to surfers catching…
‘Flashes of Creation’ recounts the Big Bang theory’s origin story
Flashes of CreationPaul HalpernBasic Books, $30 The Big Bang wasn’t always a sure bet. For several decades in the 20th century, researchers wrestled with interpreting…
50 years ago, physicists thought they found the W boson. They hadn’t
The W particle may have been found — Science News, August 21, 1971 Physicists distinguish four different kinds of force by which objects in the…
With a powerful laser blast, scientists near a nuclear fusion milestone
With a powerful laser zap, scientists have blasted toward a milestone for nuclear fusion. A fusion experiment at the world’s biggest laser facility released 1.3…
How particle detectors capture matter’s hidden, beautiful reality
At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail,…
A bounty of potential gravitational wave events hints at exciting possibilities
A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.” By loosening the criteria for what qualifies as…
Black holes born with magnetic fields quickly shed them
Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields. Unlike…
With Steven Weinberg’s death, physics loses a titan
Mythology has its titans. So do the movies. And so does physics. Just one fewer now. Steven Weinberg died July 23, at the age of…
These weird, thin ice crystals are springy and bendy
Try to bend an icicle and it’ll snap in two. With its tendency to crack into shards, ice’s reputation for being stiff and brittle seems…
Morphing noodles start flat but bend into curly pasta shapes as they’re cooked
This pasta is no limp noodle. When imprinted with carefully designed arrangements of grooves, flat pasta morphs as it cooks, forming tubes, spirals and other…
A study of Earth’s crust hints that supernovas aren’t gold mines
A smattering of plutonium atoms embedded in Earth’s crust are helping to resolve the origins of nature’s heaviest elements. Scientists had long suspected that elements…
A newfound quasicrystal formed in the first atomic bomb test
In an instant, the bomb obliterated everything. The tower it sat on and the copper wires strung around it: vaporized. The desert sand below: melted.…
Record-breaking light has more than a quadrillion electron volts of energy
The cosmos keeps outdoing itself. Extremely energetic light from space is an unexplained wonder of astrophysics, and now scientists have spotted this light, called gamma…
Laser experiments suggest helium rain falls on Jupiter
Sprinkles of helium rain may fall on Jupiter. At pressures and temperatures present within the gas giant, the hydrogen and helium that make up the…
In a first, neutrinos were caught interacting at the Large Hadron Collider
The Large Hadron Collider’s claim to fame is its ability to unveil elusive subatomic particles. But there’s one class of particle that it had never…
Nuclear clocks could outdo atomic clocks as the most precise timepieces
Nuclear clocks could be the GOAT: Greatest of all timepieces. If physicists can build them, nuclear clocks would be a brand-new type of clock, one…
Physicists dream big with an idea for a particle collider on the moon
If you could peer into a particle physicist’s daydream, you might spy a vision of a giant lunar particle accelerator. Now, researchers have calculated what…
Mathematician J. Ernest Wilkins Jr. was a Manhattan Project standout despite racism
The Manhattan Project brought together the finest scientific minds in the United States for one urgent purpose: to build an atomic bomb. That included people…
Physicists used LIGO’s mirrors to approach a quantum limit
Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to…
A proposed ‘quantum compass’ for songbirds just got more plausible
Scientists could be a step closer to understanding how some birds might exploit quantum physics to navigate. Researchers suspect that some songbirds use a “quantum…
