Researchers discovered that tertiary lymphoid structures within tumors contain stem-like T cells that specifically target the tumor. This finding reveals a potential reservoir for sustained anti-tumor immune responses, offering insights for improving cancer immunotherapies.

Astronomers have detected a planetary-mass exomoon orbiting a brown dwarf, a substellar companion to a star. The discovery, based on observational data, provides rare evidence of a moon-like body outside our solar system. It challenges current models of moon formation and expands our understanding of planetary systems.

Researchers have developed a method to improve the precision of DNA base editing by integrating AlphaFold3's contact modeling. This approach predicts how editing enzymes interact with DNA, reducing off-target effects. The technique could enhance the safety and accuracy of gene therapies for genetic disorders.

Scientists have developed a topological photonic structure that guides light along multiple pathways without scattering, eliminating the need for insulating materials. This advance could enable more robust and efficient optical circuits for communications and computing.

Researchers have developed a molecule that leverages electronic resonance to significantly improve the efficiency and stability of perovskite solar cells. This breakthrough, published in Nature, could accelerate the adoption of cheaper and more efficient solar technology. It matters because it addresses key barriers to commercializing perovskite solar cells.

Researchers determined the molecular structures of the Crimean-Congo hemorrhagic fever virus (CCHFV) polymerase and demonstrated how substrate analogs can inhibit its RNA synthesis activity. The findings provide a blueprint for designing antiviral drugs against this deadly tick-borne virus, which currently has no approved vaccines or specific treatments. This structural insight is a critical step toward combating outbreaks that pose a significant global health threat.

Researchers are investigating new cooling methods beyond traditional air conditioning, which may not be enough to keep people safe during extreme heatwaves. Potential alternatives include reflective materials, personal cooling devices, and urban design changes. Finding effective solutions is crucial for adapting to climate change and reducing energy demand.

NASA's Artemis II crew, including astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, are advancing their training and mission preparations for a lunar flyby. This mission will be the first crewed test of the Space Launch System and Orion spacecraft, paving the way for future Moon landings. Its success is critical for ensuring crew safety and validating systems for the Artemis III landing attempt.

Researchers have developed a method to access geothermal energy from any location, not just geologically active areas. This breakthrough could provide a constant, clean energy source worldwide, reducing reliance on fossil fuels. It matters because it addresses a key limitation of geothermal power: geographic restriction.
