LHAASO's high-precision measurement of the helium spectrum above 0.1 PeV: New Clues to the Origin of High-Energy Cosmic Rays

Recently, the Large High Altitude Air Shower Observatory (LHAASO) achieved a breakthrough in high-precision, element-resolved measurements of cosmic-ray spectra in the "knee" region. The LHAASO Collaboration has observed unexpected variations in the flux of helium nuclei in cosmic rays as a function of energy per nucleus, along with novel features in the evolution of cosmic ray abundance resulting from these variations. The results were published online on March 26, 2026, in Physical Review Letters (Phys. Rev. Lett. 136, 121001 (2026)); the paper was selected as an Editors' Suggestion and featured by APS Physics. The work was led by the Institute of High Energy Physics, Chinese Academy of Sciences, with collaborators from Sapienza University of Rome and other institutions. The corresponding authors, all from the Institute of High Energy Physics, are WANG Liping, MA Lingling, ZHANG Shoushan, and CHEN Suhong.

A New Method for Predicting Individualized Onset Time of Alzheimer's Disease

A New Method for Predicting Individualized Onset Time of Alzheimer's Disease

The pathological process of Alzheimer’s disease (AD) begins decades before the onset of clinical dementia symptoms. In recent years, the efficacy of newly approved anti-amyloid-beta (Aβ) therapies has been shown to depend critically on early intervention, making accurate prediction of individual dementia onset time in the pre-symptomatic stage an urgent clinical need. However, existing approaches often overlook the temporal heterogeneity among different biomarkers and typically rely on longitudinal follow-up data, limiting their applicability in real-world clinical settings where only single cross-sectional assessments are available.

Secondary Batteries Research Group Published Perspective Article in Advanced Materials

A research team led by DONG Kang and CHANG Guangcai from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences, in collaboration with SUN Xueliang's team from the Eastern Institute of Technology, Ningbo, recently published a perspective article in the prestigious materials science journal Advanced Materials. The article, titled "Unraveling Working and Degradation Mechanisms of Energy Storage and Conversion Materials at the Nanoscale Using Synchrotron X-Ray Characterizations," highlights the use of synchrotron radiation techniques for studying energy materials.

First Beam Delivered at the First Beamline of CSNS-II

First Beam Delivered at the First Beamline of CSNS-II

On March 5, 2026, the Neutron Technology Development Station at the China Spallation Neutron Source (CSNS) of the Institute of High Energy Physcis of the Chinese Academy of Sciences successfully delivered its first neutron beam and entered beam commissioning. Preliminary results from beam performance tests met expectations. This marks the successful completion of the equipment development and installation, making it the first beamline under CSNS-II to achieve beam delivery since construction began in January 2024.

A Novel Method for Detecting Cosmic Neutrino Background

Recently, Professor ZHOU Shun from the Institute of High Energy Physics of the Chinese Academy of Sciences, and Professor HUANG Guoyuan from China University of Geosciences (Wuhan) have jointly proposed a novel method for detecting the Cosmic Neutrino Background (CνB). The main strategy is to capture the signals of relic neutrinos from the Big Bang by leveraging the parametric fluorescence effect, and the relevant results were published online in Physical Review Letters on February 24 [Phys. Rev. Lett. 136 (2026) 081003].

Tibet ASγ Experiment Sheds New Light on Cosmic Rays Acceleration and Propagation in Milky Way

Tibet ASγ Experiment Sheds New Light on Cosmic Rays Acceleration and Propagation in Milky Way

For the first time ever, the Tibet ASγ experiment has achieved the measurement of magnetohydrodynamic (MHD) turbulence within the gamma-ray halo surrounding the Geminga pulsar wind nebula (PWN), with the scale being less than one parsec (roughly 3.3 light-years). This innovative observation reaches the highest energy realm—exceeding 100 tera-electron volts (TeV)—and provides unparalleled understanding of how cosmic rays and magnetic fields behave in the Milky Way. These important research results were released in Science Advances on March 4.
