Inside a beam of light, there are places where the light simply isn’t. Not dim, not scattered, not absorbed. Absent, a void of zero intensity threading through the beam like a knotted vein of darkness. These are phase singularities: points where the electromagnetic phase becomes undefined, where the wave collapses into nothing. They dart through … Read more
A single bubble, roughly the width of a human hair, rises through a column of thick fluid. It is doing two things at once. As it ascends, it drags surrounding liquid upward with it, pulling material across centimeters of space in a broad, slow convection loop. And simultaneously, because a piezoelectric transducer bolted to the … Read more
When the Canyon Diablo meteorite punched through the Arizona desert some 50,000 years ago, it carried with it a strange passenger. Locked inside fragments of the impactor, crystallographers in the 1960s found what appeared to be a new form of carbon, structurally distinct from ordinary diamond, its atoms stacked in a different geometric pattern. They … Read more
Inside a vacuum chamber in Hefei, China, a thread of glowing plasma hangs in space. Argon gas feeds into the device at five milligrams per second — barely a trickle. Electromagnetic forces tear the gas apart into ions and electrons, then hurl it backward at extraordinary speed. The thrust produced is, on its face, modest: … Read more
The quantum state exists in one place. Then it exists in another. Nothing physical moved between them — not an electron, not a photon carrying the information. Just the spooky correlations of entanglement doing what Einstein famously refused to believe they could do. Quantum teleportation is, in this sense, genuinely strange every time it works. … Read more
The Chinese suanpan has been around for roughly 1,000 years. Slide a bead up, slide a bead down — each rod operates independently, and the number it represents depends only on where the beads sit. Break one rod and the rest carry on just fine. It is, in a sense, the world’s most fault-tolerant calculator. … Read more
Fusion plasmas have been hitting the same density wall for 40 years. Push the fuel concentration too high and the reactor fails within seconds, ending the shot in a cascade of instability. That empirical limit, known as the Greenwald density, has been one of fusion’s most frustrating constraints, because the denser the plasma, the more … Read more
After seven decades of debate, an ultra sensitive observatory in China has finally tied a puzzling kink in the cosmic ray spectrum to ravenous black holes. In two new studies in National Science Review and Science Bulletin, an international team working with the Large High Altitude Air Shower Observatory (LHAASO) shows that black hole powered … Read more
When a defunct satellite spins out of control in Earth’s orbit, it becomes a deadly projectile threatening operational spacecraft. Now, Chinese researchers have developed an ingenious solution: flexible robotic rods equipped with self-adjusting dampeners that can stabilize tumbling space debris while suppressing their own violent shaking. The system combines piezoelectric actuators with advanced mathematics to … Read more
Hong Kong’s Kowloon Peninsula might be one of the most studied urban climate zones on Earth, yet it continues heating up at an alarming rate. New research reveals why standard cooling solutions—from ventilation corridors to energy-efficient buildings—have failed to stop rising temperatures in dense cities. The study, published in City and Built Environment, shows that … Read more
