Tracing Ancestry, Researchers Produce a Genetic Atlas of Human Mixing Events
The rise and fall of empires, the march of armies, the flow of trade routes, the practice of slavery — all these events have led to a mixing of populations around the world. Such episodes have left a record in the human genome, but one that has so far been too complex to decipher on […] (Source: Biosingularity)

‘On’ switches for cells
Whether human or animal, vertebrate or invertebrate, nearly every creature begins life as a tiny clump of cells. Before those cells can begin blossoming toward being a fully formed organism, however, they first must reorganize themselves into layers, each of which goes on to form complex structures such as internal organs, skin, muscle, and bone. […] (Source: Biosingularity)

The Creative Brain How Insight Works
It is a feeling we all know – the moment when a light goes on in your head. In a sudden flash of inspiration, a new idea is born. Today, scientists are using some unusual techniques to try to work out how these moments of creativity – whether big, small or life-changing – come about. […] (Source: Biosingularity)

Split brain behavioral experiments
To reduce the severity of his seizures, Joe had the bridge between his left and right cerebral hemisphers (the corpus callosum) severed. As a result, his left and right brains no longer communicate through that pathway. (Source: Biosingularity)

‘ Stressed ’ Stem Cell Breakthrough
Researchers have transformed specialized cells into an embryonic-like state simply by stressing them out a bit—an unexpected finding that may offer an easier route for treating diseases with patient-specific stem cells. Stem cells that can become all other tissue types are typically obtained in two ways. One requires the destruction of an embryonic clone of […] (Source: Biosingularity)
