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.

Scientists map all yeast proteins across cell cycle for the first time

An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.

University of Arizona researchers awarded $1.8M grant to investigate HPV's cellular invasion

Researchers at the University of Arizona College of Medicine – Tucson were awarded a $1.8 million grant by the National Institute of General Medical Sciences, a division of the National Institutes of Health, to learn how human papillomavirus makes its way to a cell's nucleus.

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.

Researchers discover key drivers behind follicular lymphoma's aggressive transformation

A team led by researchers at Weill Cornell Medicine has identified important drivers of the transformation of a type of blood cancer called follicular lymphoma from a slow-growing form to the aggressive form it takes in some patients.

Cells' built-in stopwatch safeguards mitosis

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells.

DNA damage in neurons crucial for creating stable memories

Just as you can't make an omelet without breaking eggs, scientists at Albert Einstein College of Medicine have found that you can't make long-term memories without DNA damage and brain inflammation. Their surprising findings were published online today in the journal Nature.

Unlocking the role of lncREST RNA in DNA replication and repair

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and repairing errors in DNA replication during cell division.
