Scientists unlock new role for nervous system in regeneration

Biologists at Tufts University have developed a computational model of planarian (flatworm) regeneration that explains how fragments of planaria determine which end should form a tail and which should form a head. The development ...

Breast milk as drug-delivery device

Treating sick babies with engineered breast milk could someday be a reality, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society. Modified cells in the liquid ...

Molecular guardians monitor chromosomes during cell division

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, miscarriages, birth defects, ...

Revealing the mysteries of early development

Zebrafish embryos are transparent and develop outside the mother's body, enabling scientists to get a detailed view of early development. A research team led by Lila Solnica-Krezel, the Alan A. and Edith L. Wolff Distinguished ...

Taming random gene changes as our bodies start to form

Scientists exploring how to tame random gene fluctuations as the embryos that become our bodies start to form have identified a control switch in the vertebrate segmentation clock of developing zebrafish. The researchers ...
