The Eyes Have It

Our bodies, with all their different features and variations, are the result of well-orchestrated processes that dictate what and how cells develop into the...
epithelial tissue

Cells’ Collective Behavior Determines Tissue Shapes

A team of researchers, including Northwestern Engineering’s Madhav Mani, has brought the world closer to understanding how living tissues and cells arrive at their...

Bacteria Stab Amoebae with Daggers

Bacteria have to watch out for amoeba. Hungry amoebae hunt them: they catch them with their pseudopodia and then absorb and digest them. However, some...

Variation at a Central Metabolic Gene Influences Male Fruit Fly Lifespan

The overexpression of an important gene that regulates energy metabolism can cause a severe shortening of lifespan in male fruit flies but has only...
DNA

We Are Much More Unique than Assumed

Every human being has a unique DNA "fingerprint". In other words, the genetic material of any two individuals can be clearly distinguished. Computational biologists...
