Researchers uncover genetic 'bridge' to leukemia progression

For cells to thrive, a complex network of three-dimensional structures assembles to read, copy and produce the genetic materials (DNA) needed for cellular function. Understanding how these structures form, and what happens ...

Visualising cell structures in three dimensions in mere minutes

Viral pathogens like the SARS-CoV-2 coronavirus change the interior structure of the cells they infect. These changes occur at the level of individual cell components—the organelles—and can provide information on how ...

Ultrashort-pulse lasers kill bacterial superbugs, spores

Life-threatening bacteria are becoming ever more resistant to antibiotics, making the search for alternatives to antibiotics an increasingly urgent challenge. For certain applications, one alternative may be a special type ...

SARS-CoV-2 uses sugars to invade human cells

Sugars found on the surface of human cells influence COVID-19 infection, according to a University of Alberta-led study that is one of the first to observe this relationship and suggests that cells in the brain might be particularly ...

Centriole instability might contribute to some cases of microcephaly

Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes. In addition, centriole ...

Effect of small polyanions on retroviruses

A retrovirus is a virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing that cell's genome. Once inside the host cell's cytoplasm, the virus uses its reverse transcriptase enzyme ...

The photoelectric properties of MAPbI3

Organic-inorganic hybrid perovskites (OIHPs) are promising in photovoltaic energy harvesting, electro-optic detection, and all-optical conversion. Understanding the atomic structure and structural instability of OIHPs is ...
