Phys.org / Light-controlled embryos reveal power of mechanical forces in human development

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, a flat and featureless ...

Phys.org / Scientists get a first look at the innermost region of a white dwarf system

Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star is a type of white dwarf that exerts a powerful magnetic field as it pulls material from the larger ...

Phys.org / Scientists map the hidden cellular 'postal codes' that shape every human face

Why do no two human faces look quite the same? Although we all follow the same biological blueprint, our features—the curve of a lip, the angle of a nose, the breadth of a jaw—diverge in endlessly subtle ways.
