Are cancers newly evolved species?

UC Berkeley molecular biologists propose that carcinogenesis – the generation of cancer – is just another form of speciation, the evolution of new species. “Cancer is comparable to a bacterial level of complexity, but still autonomous, that is, it doesn’t depend on other cells for survival; it doesn’t follow orders like other cells in the […]

Researchers Map Neuron Connections




Many neuroscientists and AI researchers believe that truly understanding how the brain works will be impossible until we can fathom how the billions of neurons are connected. Now, researchers at the Salk Institute for Biological Studies believe they have overcome a major hurdle to preparing such a map: identifying all of the connections to a […]

Sperm Precursor Cells Could Be Source Of Embryonic Stem Cells




Researchers, writing in the Proceedings of the National Academy of Sciences, say they a step closer to coaxing sperm stem cells to behave like embryonic stem cells, which are capable of growing into many other types of cells in the body. The new work has many potential applications, including a possible alternative to embryonic stem […]

Umbilical Cord Blood May Overcome Stem Cell Stumbling Block




A report appearing in the journal Cell Proliferationdetails how researchers, from the University of Texas and Kingston University in the U.K., have produced embryonic-like stem cells from umbilical cord blood. The breakthrough, providing an ethical and reliable source of human stem cells, could substantially speed up the development of new treatments for life-threatening illnesses, injuries […]

First Steps Taken To Build A Brain




The journal Neurosurgery has reported on work conducted by scientists in Sweden, Norway and the U.S. which has successfully produced functioning neurons from adult stem cells. Importantly, the newly grown neurons were capable of communicating through synapses. The researchers believe their work holds promise for treating patients with degenerative conditions such as Parkinson’s disease and […]
