Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

Pasca Lab specializes in growing three-dimensional organoid models from reprogrammed stem cells, which capture molecular changes during fetal brain-like development. Because the human brain cannot be ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to ...

Dendritic cells (DCs) are among the first immune sentinels to detect viruses, bacteria, or other challenges. These specialized messengers alert T cells while orchestrating either a measured calm or a ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.

Researchers in Japan have identified a striking new way immune cells strip DNA out of dying neighbors, a process they call ...

Scientists at Duke-NUS Medical School have identified a molecular “switch” that determines whether pancreatic cancer cells resist chemotherapy or respond to it—a finding that could help convert some ...

The long-term stasis of blood in the liver, known as chronic liver congestion, can lead to a range of diseases, some of which ...
