Insights into genomic instability during the early stages of embryonic cell development
The environment within a cell is a paradoxical balance of order and chaos. Proteins, DNA and countless other biological molecules tumble together in a wildly turbulent system that somehow holds together to engender life.
Simple technology makes CRISPR gene editing cheaper
University of California, Berkeley, researchers have discovered a much cheaper and easier way to target a hot new gene editing tool, CRISPR-Cas9, to cut or label DNA.
Fruitfly sperm cells reveal intricate coordination in stem cell replication
Stem cells are key for the continual renewal of tissues in our bodies. As such, manipulating stem cells also holds much promise for biomedicine if their regenerative capacity can be harnessed. However, understanding how stem ...
Hippo dances with hormones: Hints from fly research for study of cancer, stem cells
Although fruit flies don't develop cancer, cancer and stem cell researchers have been learning a great deal from fruit flies - in particular, mutant flies with overgrown organs that resemble hippopotamuses.
Network of tubes plays a key role in plants' immune defense
Chloroplasts, better known for taking care of photosynthesis in plant cells, play an unexpected role in responding to infections in plants, researchers at UC Davis and the University of Delaware have found.
Discovering a new force driving cell contraction during development and organogenesis
CRG scientists describe a new mechanism shaping cells and generating cell contractile forces during development and organogenesis. The new mechanism, which has been published today in the journal Developmental Cell, includes ...
Biologists demonstrate how signals in plant roots determine the activity of stem cells
The roots of a plant are constantly growing, so that they can provide the plant with water and minerals while also giving it a firm anchor in the ground. Responsible for these functions are pluripotent stem cells. In order ...
Understanding how cells become coronary vessels may lead to advances in repairing heart damage
The heart has its own dedicated blood supply, with coronary arteries that supply oxygen-rich blood to the heart and cardiac veins that remove deoxygenated blood. This system of vessels nourishes the heart, enabling it to ...
Blueprints for the construction of nuclear pores deciphered
In a recent study, a team of researchers led by Alwin Köhler at the Max F. Perutz Laboratories (MFPL) belonging to the University of Vienna and the Medical University of Vienna offer new insights into how nuclear pores are ...
