Newly discovered protein helps preserve egg chromosome integrity during aging
Eggs follow a very different developmental path from sperm. Once a male hits puberty, sperm cells are produced…
Shared meiosis proteins show surprising functional differences across animals
Every egg cell and sperm cell depends on meiosis, a tightly choreographed process in which chromosomes find their…
DNA Typewriter Chronicles Cell Lineage of Mouse Embryo
A DNA ‘typewriter’ records the history of 1.3 million cells in an early mouse embryo, telling the tale…
ESCRT-III proteins play an unexpected role in protecting DNA bridges during cell division
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However,…
Scientists create first man-made cell that can eat and grow
For centuries, humanity has wrestled with a profound question: what truly separates non-living matter from actual, breathing life?…
Study reveals how cells regulate spindle formation during division
During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes…
Chromosome abnormalities may help cancer cells resist treatment and spread
A new study led by NYU Langone Health researchers found that cancer cells are better able to resist…
Exploiting a new weakness in ‘zombie-like’ cells to treat senescence-associated diseases
A new set of drugs exploit a recently-revealed weakness in ‘zombie-like’ – or senescent – cells that could lead to new treatments for cancer and age-associated diseases. The study from the…
Study reveals dual role of PFK enzyme in metabolism and cell cycle progression
A metabolic enzyme studied for over seven decades has a hidden second function – it can unwind RNA…
Scientists simulate complete life cycle of a minimal bacterial cell
By simulating the life cycle of a minimal bacterial cell – from DNA replication to protein translation to…
