Researchers discover new class of stem cells

Researchers have identified a new class of lab-engineered stem cells-cells capable of transforming into nearly all forms of tissue-and have dubbed them F-class cells because they cluster together in "fuzzy-looking" colonies.

Identifying the source of stem cells

When most animals begin life, cells immediately begin accepting assignments to become a head, tail or a vital organ. However, mammals, including humans, are special. The cells of mammalian embryos get to make a different ...

Study dusts sugar coating off little-known regulation in cells

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically ...

New type of extra-chromosomal DNA discovered

(PhysOrg.com) -- A team of scientists from the University of Virginia and University of North Carolina in the US have discovered a previously unidentified type of small circular DNA molecule occurring outside the chromosomes ...

Alan Turing's 1950s tiger stripe theory proved

Researchers from King's College London have provided the first experimental evidence confirming a great British mathematician's theory of how biological patterns such as tiger stripes or leopard spots are formed.

A knockout resource for mouse genetics

An international consortium of researchers report today in Nature that they have knocked out almost 40 per cent of the genes in the mouse genome. The completed resource will power studies of gene activity in models of human ...

Mutant mouse reveals new wrinkle in genetic code

(PhysOrg.com) -- Call it a mystery with a stubby tail: an odd-looking mouse discovered through a U.S. government breeding program in the 1940s that had a short, kinky tail and an extra set of ribs in its neck – and nobody ...
