Unexpected discovery on the study of stem cell immortality

[ad_1] Telomeres are the protective caps at the ends of chromosomes. In adult cells, telomeres shorten each time a cell divides and this contributes to aging and cancer. Pluripotent stem cells, however, are specialized cells that exist in the early days of development. These pluripotent cells do not age and …

Direct visualization of the quantum dots reveals the shape of the quantum wave function of the trapped electrons

[ad_1] Visualization of quantum dots in bilayer graphene using microscopy and scanning tunneling spectroscopy reveals triple symmetry. In this three-dimensional image, the peaks represent high-amplitude sites in the waveform of the trapped electrons. Credit: Zhehao Ge, Frederic Joucken and Jairo Velasco Jr. The researchers used a scanning tunnel microscope to …
