• New brain mapping reveals unknown cell types

  19-02-2015 20:13
  
  Using a process known as single cell sequencing, scientists have produced a detailed map of cortical cell types and the genes active within them. The study marks the first time this method of analysis has been used on such a large scale on such complex tissue. The team studied over three thousand cells, one at a time, and even managed to identify a number of hitherto unknown types.

• Mouse embryo with big brain: Evolving a bigger brain with human DNA

  19-02-2015 19:31
  
  The human brain expanded dramatically in size during evolution, imparting us with unique capabilities. Scientists have now shown that it's possible to pick out key changes in the genetic code between chimpanzees and humans and visualize their respective contributions to early brain development in mouse embryos. The findings may lend insight what makes the human brain special and why people get some neurological disorders, such as autism and Alzheimer's disease, whereas chimpanzees don't.

• Stem cell specialization observed in the brain

  19-02-2015 16:15
  Adult stem cells are flexible and can transform themselves into a wide variety of special cell types. Because they are harvested from adult organisms, there are no ethical objections to their use, and they therefore open up major possibilities in biomedicine. For instance, adult stem cells enable the stabilization or even regeneration of damaged tissue. Neural stem cells form a reservoir for nerve cells. Researchers hope to use them to treat neurodegenerative disorders such as Parkinson's and Al

• Sickness and health between men and women

  19-02-2015 15:03
  Gender and personality matter in how people cope with physical and mental illness, according to a new paper. Men are less affected by a single-symptom illness than women, but are more affected when more than one symptom is present. The number of symptoms doesn't change how women are affected, according to the authors.

  Many people encounter passive aggressive-behaviour on a regular basis. Many people even use it, perhaps unknowingly. How can something seemingly self-contradicting become so common? And why is it so jarring, even when compared to straightforward ‘normal’ aggression?It was Valentine’s Day recently, a fraught time for anyone in a relationship. Perhaps the gift you got your partner was obviously a last minute purchase from a petrol station? Or maybe you ignored Valentine’s Day because you b
