Brain scans have uncovered two biologically distinct forms of autism hidden within the spectrum. An international team of researchers has identified at least two biologically distinct forms of autism by examining how different regions of the brain communicate with one another. The findings could help advance more precise and personalized approaches to autism care and [...]

Researchers have uncovered a previously underappreciated mechanism involved in Alzheimer’s disease and developed a compound that interrupts it. For decades, Alzheimer’s research has largely focused on amyloid plaques and tau tangles, the protein abnormalities that accumulate in the brain as the disease progresses. Yet despite billions of dollars in research and numerous drug development efforts, [...]

A new study reveals that an extremely small change in a non-coding region of DNA can dramatically alter how sex develops in mice. How much can a single letter of DNA matter? According to new research from Bar-Ilan University, one misplaced genetic “letter” can completely change the course of sexual development. In a study published [...]

A closer look at cancer cells with extra chromosomes uncovered surprising traits linked to faster-growing, more dangerous tumors, pointing to potential new indicators of disease severity. Cancer cells are notorious for breaking the rules of biology. One of the most dramatic violations occurs when a cell suddenly doubles its entire genetic library, creating a chromosome-packed [...]
