New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and ...

CellVoyant, a U.K.-based startup, has launched an AI platform that allows scientists to predict the future health and ...

Brain organoids can be a good step forward, assuming they are grown from induced human pluripotent stem cells. That allows us to sidestep ethical concerns about the use of human embryos, thereby ...

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too ...

If a pig embryo infused with human cells truly became something close enough to count as a member of the human species, then current research regulations would dictate it’s owed human-level regard.

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and ...

A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, ...

Organoids are bits of neural tissue that model human brain development. Their use in science makes some uneasy, in part because the brain is so closely tied to our sense of self.

Creatine plays a vital role in the body's energy system, but it also points to effects beyond "energy" that help brain and ...

Liver disease is a major global health problem, causing over two million deaths worldwide each year. While animal models have ...

The humble planarian flatworm can regrow its brain. Here’s how this tiny animal will have you rethinking everything you ...
