Scientists have succeeded in reconstructing the family tree of cells in a developing mouse embryo. They recorded cells' relationships, starting when the fertilized egg first split in two and ending ...

Immune cells are the elite athletes of the human body. While other cells stay in place, immune cells travel throughout our bodies, squeezing through small channels, stretching themselves, sampling the ...

(Agnes Noy/Catley et al., Nucleic Acids Research, 2026) If you could peer inside a cell's nucleus, you would find DNA tightly ...

The DNA in our cells wraps around proteins called histones to form nucleosomes, which organize into chromatin. This ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

Zebrafish neural crest cells migrating through extremely confined embryonic tissues deform their nuclei dramatically yet ...

Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell ...

Learn how DNA can be exchanged between two cells that connect by forming nanotubes, and find out why this is crucial for cancer research. When cells in our body are going through a rough patch due to ...

A multicancer genomic analysis links mitochondrial DNA copy number with mutation burden and gene expression relevant to ...

Ancient DNA and proteins identify China’s nearly complete “Dragon Man” skull as Denisovan. The fossil, at least 146,000 years ...
