The last advances in genetics and genomics are leading a change in the paradigm about how to treat diseases. Epigenetics is the science field that studies how gene expression is regulated. Several modifications on the genes such as DNA-methylation, histone-acetylation or microRNA (miRNA) regulation are considered to be the main responsible in controlling gene expression […]

A switch for internal, external brain processes Researchers have observed how the brain switches between internal and external information processes in mice. Scientists manipulated thalamic reticular nucleus cells to get the mice to switch information systems. Researchers hope the study could lead to treatments for people with autism or schizophrenia, whose brains have difficulty with […]

Glowing sharks living in dark depths evolve special vision Some species of bioluminescent sharks that live in the darkest depths of the ocean have eyes that have evolved to detect complex patterns of light to communicate with each other, locate prey or hide themselves. Researchers found that the eyes of bioluminescent sharks provide better resolution […]
