New solar system models show Earth is no fluke

Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points.

‘Rainbow-on-a-chip’ could help unlock 6G networks and precision timing for quantum technologies

Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into multiple high-frequency electromagnetic signals known as millimeter waves.

Interplanetary spacecraft capture a coronal mass ejection component hidden from Earth

During a coronal mass ejection (CME), the sun hurls billions of tons of magnetized plasma into space. These eruptions are among the most powerful events in the solar system, and when they are aimed toward Earth, they can seriously threaten the satellites and power grids we depend on. For now, it remains notoriously difficult to predict how these eruptions evolve over time—and, in turn, whether they might be heading toward us.

China is launching a moon mission to find water ice

We’ve known for nearly two decades that some form of water exists on the moon. What we still don’t know is exactly how much accessible water ice lies inside permanently shadowed craters, how deeply it is buried or what form it takes.

Century-old physics idea explains why cubic fluid equations work

The Korea Institute of Civil Engineering and Building Technology (KICT) has developed a new cubic equation of state (EOS) that provides a physical justification for a mathematical structure that the chemical and petroleum industries have relied on for more than half a century without a first-principles explanation.

Intense light bent out of shape—ultrafast lenses made from gas

Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- and X-ray pulse control for applications such as chemical reaction steering, quantum computing, and advanced spectroscopy methods for fundamental science. The paper is published in the journal Science Advances.

Magnetically levitated quantum bit could address design flaws

Researchers at the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory, headquartered at Florida State University, have designed a new quantum computing architecture that uses magnetic levitation to smooth over design flaws in the intricate components necessary to run a quantum computer.

AI boosts sensitivity to double-Higgs signatures occurring about once per trillion collisions

Is the universe as stable as we think it is? That’s one of the big questions that particle physicists worldwide are preparing to answer with the Large Hadron Collider, or LHC—the world’s most powerful particle accelerator—when its upgrade is completed in about four years. In the meantime, researchers, including a cohort at the University of Michigan, are working to sharpen their analytical tools and techniques to make the most of the LHC’s current and future data.

New measurements explain how silicon and diamond achieve extreme reversible stretching

A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent semiconductors such as silicon and diamond. The discovery provides quantitative guidance for deep elastic strain engineering (DESE), paving the way for the development of next-generation electronic, optoelectronic and quantum devices.

Newton’s momentum principles could help design safer offshore facilities in extreme waves

Researchers have developed a novel model to accurately and efficiently predict the impact of “green water”—water washing onto the deck of an offshore facility during extreme wave conditions.

A little Big Bang: Bowling-pin-shaped nuclei shed new light on the universe’s first moments

What happened in the first moments of the universe—before the building blocks of life and the world we know today came into existence? Physicists at the CERN research facility in Switzerland are trying to answer this question by recreating some of the extreme conditions that prevailed in the universe during its earliest history. Now, researchers from the Niels Bohr Institute, together with colleagues from the international ALICE collaboration, have come one step closer to understanding those conditions.
