Giant virus takes down deadly brain parasite

The single-celled organism Naegleria fowleri ranks among the deadliest human parasites. Researchers around Matthias Horn and Patrick Arthofer from the Center for Microbiology and Environmental Systems Science at the University of Vienna, in an international collaboration, have discovered viruses that infect this harmful microbe.

Timelapse breakthrough: Scientists capture secrets of early embryonic cell division

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is 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 our bodies, the embryonic cells.

Neurons re-entering cell cycle succumb to senescence in neurodegenerative diseases

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study published April 9th in the open-access journal PLOS Biology by Kim Hai-Man Chow and colleagues at the Chinese University of Hong Kong.

Cells use liquid droplets to regulate signaling pathways, study finds

Healthy cells respond appropriately to changes in their environment. They do this by sensing what's happening outside and relaying a command to the precise biomolecule in the precise domain that can carry out the necessary response.

Study explores the effects of ovulation inducing method on embryo quality

Low birth rates have become a serious problem in many developed countries throughout the world, with Japan being a prime example. In Japan particularly, aging and stress have led to a massive rise in infertility, which now affects one in every 4.4 couples.

Bacterial cell division: Rethinking size regulation

When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass.
