A new study claims that early childhood experiences can change a person's brain structure long-term and in irreversible ways - even if the brain heals.
Professor Cordula Hoelig, a psychologist and neuroscientist, and a researcher at the University of Hamburg in Germany, worked with the LV Prasad Eye Institute in Hyderabad, India, to study people who had been left blind for years after birth due to cataracts but who had had their sight restored thanks to surgery.
The researchers used Magnetic Resonance Imaging technology to make images of people's brains. The 3D models, all made of people who were between the ages of 6 and 36 at the time of the study, allowed the researchers to measure the thickness and size of the visual cortex. A researcher said the study shows that early childhood experiences such as poverty and neglect"can change brain structure long-term and, apparently, irreversibly."

Evidence that early galaxies may be bigger and more complex than previously thoughtScientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— an international observatory co-operated by the U.S. National Science Foundation's National Radio Astronomy Observatory (NRAO)—have observed a significant amount of cold, neutral gas in the outer regions of the young galaxy A1689-zD1, as well as outflows of hot gas coming from the galaxy's center. These results may shed light on a critical stage of galactic evolution for early galaxies, where young galaxies begin the transformation to be increasingly like their later, more structured cousins. The observations were presented today in a press conference at the 240th meeting of the American Astronomical Society (AAS) in Pasadena, California, and will be published in an upcoming edition of The Astrophysical Journal (ApJ).
