Those attending the American Physical Society (APS) March meeting at the Minneapolis Convention Center next week will no doubt be looking forward to the many physics talks on offer. This year’s APS March meeting also celebrates the 125th anniversary of the APS and physicists can mark the occasion by belting out a few tunes at the meeting’s annual physics sing-along. Organized by physicist Walter Smith from Haverford College, this year’s get together will be held on 6 March at the Hyatt Regency Hotel from 9:00 – 10:30 p.m. It will feature songs such as “Problem Set”, set to “Tainted Love ..read more

Matter–antimatter gas of positronium is laser cooled

1d ago
Researchers at CERN and the University of Tokyo have independently laser-cooled clouds of positronium. The breakthrough should make it easier to make precision measurements of the properties of antimatter and allow researchers to produce more antihydrogen. Positronium is an atom-like bound state of an electron and its antiparticle the positron. As a hybrid of matter and antimatter, it is created in the lab to allow physicists to study properties of antimatter. Such studies could reveal physics beyond the Standard Model and could explain why there is much more matter than antimatter in the visi ..read more

Increasing access to radiotherapy: playing the long game
Physics World

The global inequity in access to radiotherapy services is systemic, hard-wired and not going away anytime soon. The data don’t lie, with the gap between radiotherapy “haves” and “have-nots” dictated, for the most part, by the economic clout of individual nation states. According to the International Atomic Energy Agency (IAEA), an intergovernmental organization that seeks to promote the peaceful use of nuclear energy, nearly all cancer patients in high-income countries have access to radiotherapy – versus fewer than 60% of patients in middle-income countries. Worse still, in low-income countri ..read more

Artificial intelligence (AI) shows great promise for use in radiology, which involves the use of medical imaging to diagnose and treat disease. Integrating AI tools into radiology could advance the diagnosis, quantification and management of multiple medical conditions. However, it is essential to acknowledge that some AI products may be add little value or even have potential to cause harm. To ensure that AI is used appropriately, five radiology societies in the US, Canada, Europe, Australia and New Zealand have come together to publish a joint statement on the development and use of AI tools ..read more

Diamond alignment makes high-pressure magnetometry of superconductors possible
Physics World

3d ago
Physicists in the US and China have devised a technique for making reliable measurements of the magnetic properties of materials held under very high pressures.  Their method could help researchers discover materials that are superconductors at high temperatures and high pressures. High-temperature superconductivity has hit the headlines regularly in the past year or two – but often for the wrong reasons. Several claims of materials that superconduct at close to or even above room temperature have been disputed, and some have been withdrawn. A part of the problem is that these materials a ..read more

Quality assurance: new approaches for ultrahigh-dose rate FLASH radiotherapy
Physics World
by No Author
3d ago
The clinical translation of FLASH radiotherapy holds great promise, with demonstrated FLASH effect, the advantageous normal tissue sparing effect under ultrahigh-dose rate (UHDR) delivery, observed in numerous preclinical studies. Nonetheless, FLASH clinical implementation presents unique challenges in ensuring the safety and accuracy of patient treatments. A rigorous and robust quality assurance (QA) program needs to be developed to address the ultrahigh-dose rate related treatment considerations. In this talk, Jennifer Wei Zou will delve into the efforts of our NRG FLASH working group, whic ..read more

Cool stuff Interior view of the Pony cryostat installed at Argonne National Laboratory in February. The Pony provides scientific users with continuous sub-Kelvin cooling and a large experimental space that is convenient to open and close. (Courtesy: Danaher Cryo) While some like it hot, others like to keep things cold – ultracold to be precise. A case study in this regard is Danaher Cryogenics, the US-based designer and manufacturer of integrated sub-Kelvin cryostat systems for diverse applications in scientific research and industrial R&D. Based out of Boulder, Colorado, the two-year-old ..read more

An ambitious journey through the cosmos that sometimes gets lost at sea

Turn off the Higgs field – an energy field thought to emanate throughout the universe – and life as we know it would cease to exist. Our bodies would explode, and Earth would detonate as the universe obliterated itself. Flick the switch the other way – so that the Higgs field is on full blast – and the cosmos and all it contains would instantly shrivel into a tiny ball of nothingness. While both scenarios might sound far-fetched, altering the strength of the Higgs field from its current “Goldilocks” value would tip the scales, as theoretical physicist Matt Strassler explains in his debut book ..read more

Electrochemical atomic force microscopy of battery interfaces
Physics World
by No Author
3d ago
  The successful deployment of materials for advanced batteries requires an in-depth understanding of the correlation between their electrochemical performance and structural and mechanical evolution across multiple length scales. The reaction kinetics of their interfacial processes must also be quantified. In situ and operando electrochemical atomic force microscopy (EC-AFM) is a powerful tool that can simultaneously reveal these relationships with nanoscale resolution [1]. By using EC-AFM to study the electrode-electrolyte interface of anode materials in lithium ion [2], zinc ion [3–5 ..read more
