Researchers at KAIST have directly observed how charge density waves form uneven, patchy patterns inside a quantum material during a phase transition. Using advanced 4D-STEM microscopy, the team mapped the strength and coherence of these electron patterns at nanoscale resolution. The findings reveal that electronic order persists in small pockets even above the transition temperature.

Scientists at the Fritz Haber Institute of the Max Planck Society and international collaborators say they have reconstructed a real-time “movie” of atoms moving for up to a picosecond before an electron-transfer-mediated decay (ETMD) event, showing that nuclear motion and geometry can strongly influence when the decay occurs and what it produces.

Researchers at Northwestern University have developed a more effective therapeutic vaccine for HPV-related cancers by rearranging components in a DNA-based nanoparticle. This structural adjustment significantly enhances the immune system's ability to target and destroy tumors. The findings, published in Science Advances, highlight the importance of molecular arrangement in vaccine design.

Scientists have created innovative nanoparticles designed to destroy harmful proteins linked to dementia and cancer. These particles can access difficult tissues like the brain and precisely eliminate problematic proteins without broad side effects. The technology shows early promise for precision medicine.

Researchers from Ohio State University and Louisiana State University have pioneered a technique to observe ultrafast molecular interactions in liquids using high-harmonic spectroscopy. In a surprising experiment with fluorobenzene and methanol, they discovered a subtle hydrogen bond that suppresses light emission. This breakthrough, published in PNAS, opens new windows into liquid dynamics essential for chemistry and biology.
