A new review highlights advancements in thermoelectric generators (TEGs) that use solar energy and radiative cooling to produce clean electricity. This breakthrough technology shows promise for off-grid power solutions and sustainable energy applications.
Researchers from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences and Columbia University, along with their collaborators, have analyzed sediments from the terrestrial Sangonghe Formation (Late Early Jurassic) in China's Junggar Basin, revealing information both on Solar System chaos and the global carbon cycle.
This collection of four pioneering studies showcases the transformative capabilities of the Large High Altitude Air Shower Observatory (LHAASO), whose unmatched sensitivity (>100 TeV) and hybrid detector system (KM2A/WCDA) are redefining ultra-high-energy (UHE) gamma-ray astronomy. Key breakthroughs include: (1) Identifying young star-forming region W43 as a Galactic cosmic-ray accelerator (up to hundreds of TeV), evidenced by extended emission coinciding with dense gas and OB stars; (2) Resolving particle acceleration to 300 TeV within the pulsar wind nebula (PWN) of composite SNR CTA1, revealing advection-dominated transport under ≈4.5 μG magnetic fields; (3) Detecting extended VHE emissions around pulsar J0248+6021, providing critical insights into PWN-to-halo evolutionary transitions; and (4) Unraveling the mysterious UHE source J0056+6346u, potentially powered by hidden pulsars or SNR candidate. These results leverage LHAASO's exceptional detector performance to constrain both particle transport dynamics and extreme acceleration mechanisms across the 1 TeV–1 PeV energy range. LHAASO is ushering in a new era of UHE astrophysics, bringing us closer than ever to solving century-old cosmic-ray mysteries.
