A shade closer to more efficient organic photovoltaics
Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitra.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
Engineers muffle invading pathogens with a "molecular mask"
Vaccines remain the gold standard of protection against dangerous pathogens, but take considerable time and vast resources to develop. Rapidly mutating viruses such as SARS-CoV-2 can blunt their effectiveness and even render them obsolete......»»
Biomolecular condensates: Study reveals poor predictive power of established liquid-liquid phase separation assays
Cells buzz with millions of different biomolecules that diffuse chaotically through their substructures, yet they manage to ensure exquisite functional and spatial specificity......»»
Research combines DNA origami and photolithography to move one step closer to molecular computers
Molecular computer components could represent a new IT revolution and help us create cheaper, faster, smaller, and more powerful computers. Yet researchers struggle to find ways to assemble them more reliably and efficiently......»»
