Drawing a line back to the origin of life: Graphitization could provide simplicity scientists are looking for
Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible conditions for life's e.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
