How stem cells self-organize in the developing embryo

Embryonic development is a process of profound physical transformation, one that has challenged researchers for centuries. How do genes and molecules control forces and tissue stiffness to orchestrate the emergence of form ...

How trees and turnips grow fatter

Two international research teams have identified key regulatory networks controlling how plants grow 'outwards', which could help us to grow trees to be more efficient carbon sinks and increase vegetable crop yields.

Indian scientists slam ancient Hindu 'stem cell' claim

The organisers of a major Indian science conference distanced themselves Sunday from speakers who used the prestigious event to dismiss Einstein's discoveries and claim ancient Hindus invented stem cell research.

How sperm stem cells maintain their numbers

The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Assistant Professor Yu Kitadate and Professor Shosei Yoshida (developmental biologists at the ...

Protein involved in nematode stress response identified

When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances—overcrowded conditions, not enough food—by completely remodeling their ...

The source of stem cells points to two proteins

Mammalian embryos are unlike those of any other organism as they must grow within the mother's body. While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such ...
