Electron cooling tames highly charged ions in Penning trap for first time

Researchers at Technical University of Darmstadt and the GSI Helmholtz Center for Heavy Ion Research have succeeded for the first time in decelerating highly charged ions from the GSI accelerator to low energies and subsequently storing them in a Penning trap. They were also successful in performing the first electron cooling of highly charged ions […]

Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers

Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk form. But now, a new study, published in Science Advances, has found that very […]

Quantum computer completes verified task beyond practical reach of classical simulations

IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for “quantum advantage”—the point where quantum computers can be confirmed to have outperformed classical computers on trusted computations.

Solar wind stirs Mars’ upper atmosphere, boosting ion loss to space

Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow. As a result, the solar wind can interact directly with Mars’ upper atmosphere and gradually strip atmospheric particles into space.

Laying odds on the potential for Martian water near future landing zones

We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars’ equator. As NASA looks toward landing humans on the red planet, the Planetary Science Institute (PSI) is mapping where water should and shouldn’t be found and using statistics to quantify its […]

Moonquakes could reveal ice buried beneath lunar south polar craters

Finding water on the moon may only be a matter of detecting the right vibrations.

Homing in on the X-ray sky with eROSITA’s second data release

The German eROSITA consortium (eROSITA-DE), which includes the University of Bonn and is led by the Max Planck Institute for Extraterrestrial Physics (MPE), has released its second major public data set, the “eROSITA Data Release 2” (DR2).

ELT’s spectrograph could ‘sniff out’ biosignatures on other worlds

Before any major telescope commissioning, there are dozens of papers that attempt to define what we can expect from it. We’re starting to see some come through for the Extremely Large Telescope (ELT), which hopefully will get a more imaginative name when the 39 m (128-foot) behemoth is officially commissioned in Chile in the 2030s.

Optimized magnetic pulses could cut memory switching energy by several orders of magnitude

Information and communication technologies (ICTs) driven by artificial intelligence (AI) are generating data at an unprecedented rate. Every internet search, AI-generated image, recommendation, scientific simulation and large language model creates and processes enormous amounts of information that must be stored, transferred and analyzed. As AI continues to expand across every sector of society, global demand […]

New open-source software predicts energy transfer between tiny defects in solid materials

The performance of many next-generation devices depends on controlling how energy flows at extremely small scales. In the field of microelectronics—where devices continue to shrink and new materials are introduced—small imperfections in solids can strongly influence how a material stores, transfers or loses energy. Those processes can either be used to improve device performance or […]

Curiosity Blog, Sols 4961-4967: Approaching a break in the rock record?

Curiosity spent the week continuing to climb her way through the layers of Mount Sharp, exploring the sedimentary rock strip chart of Martian history. The rover has reached a layer where the science team had spotted a possible “erosional supersurface” by analyzing orbital data alongside images of the layers in the buttes above us.
