Researchers discover a new gear in life's clock: Vitamin D

New research from Portland State University finds vitamin D, or a lack thereof can trigger or suspend embryonic development in a species of fish. The study also provides evidence suggesting the vitamin is critical to the ...

Evolving a bigger brain with human DNA

The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger than that of our ...

Rewinding development: A step forward for stem cell research

Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta cells as well ...

Embryo development obeys the laws of hydrodynamics

Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a folded pancake. He demonstrated ...

The developmental on-switch

German researchers have demonstrated for the first time why the molecular cocktail responsible for generating stem cells works. Sox2 and Oct4 are proteins whose effect on cells resembles that of an eraser: They remove all ...
