Ultrahigh-energy cosmic messengers may carry ultraheavy secrets

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed. Ultrahigh-energy cosmic rays are particles from space that strike Earth with energies far beyond those reachable by human-made particle accelerators. One of the most extreme events ever recorded is the “Amaterasu particle,” detected by the Telescope Array in Utah in 2021 and named after the sun goddess in Japanese mythology. Its reported energy places it among the highest-energy cosmic-ray events ever observed, comparable to the “Oh-My-God particle” detected in 1991, yet its origin—and even its identity—remain uncertain.

Next-gen Mars helicopter rotor blades exceed Mach 1

The rotor blades that will carry NASA’s next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA’s Jet Propulsion Laboratory in Southern California. Data from the tests, which took place in a special chamber that can simulate environmental conditions on the Red Planet, indicate that the fastest traveling part of the rotor blade, the tips, can be accelerated beyond Mach 1 without breaking apart. Data gathered from 137 test runs will enable engineers to design aircraft capable of carrying heavier payloads, including science instruments.

Quantum metallurgy: Electron crystals deform and melt

In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns that can deform and melt, opening new pathways for neuromorphic computing and superconductors, University of Michigan Engineering researchers have found.

LED light unlocks 3D optical fingerprints inside materials without lasers

Researchers have developed, for the first time in the world, incoherent dielectric tensor tomography (iDTT), a technology that can read complex three-dimensional optical fingerprints inside materials using only everyday LED illumination.

Mobile qubits on a chip move us a step closer to everyday quantum computers

For years, quantum computers have lived under a huge bubble of hype, promising to revolutionize numerous fields, from medicine and battery design to materials science and cybersecurity. But realizing their potential on any serious practical level will only be possible if large numbers of qubits (the basic units of information) can interact with each other with high precision and flexibility.

Photonics advance could enable compact, high-performance lidar sensors

Lidar systems use pulses of infrared light to measure distance and map a 3D scene with high resolution, allowing autonomous vehicles to rapidly react to obstacles that appear in their path. But traditional lidar sensors are expensive, bulky systems with many moving parts that degrade over time, limiting how the sensors can be deployed.

Magnetic checkerboard separates microparticles by size and sends them along different paths

A team of researchers from the Universities of Tübingen, Bayreuth, and Kassel, and the Polish Academy of Sciences has developed a method for precisely controlling the movement of magnetic microparticles based on their size. These suspended particles, known as colloidal particles, range in size from a few tens of nanometers to several micrometers. Controlling them is important for applications such as drug delivery, medical laboratory tests, and the synthesis of new materials. The team’s study has now been published in Physical Review Letters.

Team steers electron spin ballistically in graphene

Researchers at The University of Manchester’s National Graphene Institute have shown that electrons in ultra-clean graphene can be steered with high precision while keeping their spin information intact, a key requirement for future low-power electronics and quantum devices.

Testing quantum collapse theory with the XENONnT dark matter detector

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle’s state is measured, however, this superposition appears to “collapse” into a single outcome; a phenomenon often referred to as the “measurement problem.”

These monster black holes did not form the usual way—their history of violence is written into spacetime ripples

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of repeated and extremely violent collision events in very densely populated star clusters, an international team of researchers argue.
