Simple genetic circuit forms stripes: Synthetic biology helps scientists sort out pattern formation
Many living things have stripes, but the developmental processes that create these and other patterns are complex and difficult to untangle. Now a team of scientists has designed a simple genetic circuit that creates a striped ...

1001 Genome-Project: On the way to a complete catalog of the Arabidopsis genome
People can develop new technologies and animals may migrate to other regions. However, plants are tied to their location. Nevertheless, they have found ways to ensure their survival. This is the case for the ...

Cells derived from pluripotent stem cells are developmentally immature
Stem cell researchers at UCLA have discovered that three types of cells derived from human embryonic stem cells and induced pluripotent stem cells are similar to each other, but are much more developmentally immature than ...

Model predicts a drug's likelihood of causing birth defects
When pregnant women need medications, there is often concern about possible effects on the fetus. Although some drugs are clearly recognized to cause birth defects (thalidomide being a notorious example), and others are generally ...

New protein promotes embryonic brain formation
The various bone morphogenetic protein (BMP) signaling factors play an important role in early neural development in the vertebrate embryo. However, maturation of these tissues ultimately depends on the coordinated ...

Fruit flies help scientists sniff out new insect repellents
By following the "nose" of fruit flies, Yale scientists are on the trail of new insect repellents that may reduce the spread of infectious disease and damage to agricultural crops. That's because they've learned for the first ...

Histone H1 regulates gene activity throughout the cell cycle
A protein that helps pack DNA into the cell nucleus has an important role in regulating gene activity, scientists report. The researchers found that the protein, histone H1, also takes part in the formation ...

Root or shoot: Power struggle between genetic master switches decides stem cell fate
The first order of business for any fledgling plant embryo is to determine which end grows the shoot and which end puts down roots. Now, researchers at the Salk Institute expose the turf wars between two groups ...

The skeleton: Size matters
Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first segments to be added ...
