Endometriosis risk linked to two pesticides
The Fred Hutchinson Cancer Research Center has found that two organochlorine pesticides are associated with an increased risk of endometriosis, a condition that affects up to 10 percent of reproductive-age women.
Fountain-of-youth gene repairs tissue in adults
Young animals recover from tissue damage better than adults, and from Charles Darwin's time until now, scientists have puzzled over why. A recent study reveals that the Lin28a gene, which is very active in embryos but not in adults, enhances tissue repair after injury when reactivated in adult mice.
Mechanism found making ordinary stem cells — tumors
Epigenetic effects on cell signaling leads healthy stem cells to create benign fibromas in the jaw, which could become harmful.

Solved — origin of biologic complexity
Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce.
Breastfeeding as a possible deterrent to autism
A New York-based physician-researcher from the Touro College of Osteopathic Medicine has called for the testing of umbilical cord blood for levels of a growth protein that could help predict an infant's propensity to later develop autism.
Further evidence of RNA origin to modern life
RNA is the key function of spliceosomes, molecular machines that control how genes are expressed — or turned on. The discovery of splicesomes establishes that RNA, not protein, is responsible for catalyzing this fundamental biological process and enriches the theory that life on earth began in a world based solely on RNA.

Early life stress worsened by later stress exposure
Childhood neglect and abuse, whether physical or psychological, confers a lifetime vulnerability to stress, anxiety, and mood problems. Such early-life stress is also suspected to contribute to the development of chronic pain in adulthood.
Brain structure in post-traumatic stress disorder
Wars, earthquakes, major traffic accidents, and terrorist attacks may bring about profound spiritual pains, and even cause extreme fear and helplessness for people that have experienced or witnessed these unusual threats or disasters.
Earlier onset of puberty in girls linked to obesity
New research in Pediatrics shows obesity is the largest predictor of earlier onset puberty in girls, which is affecting white girls sooner than previously reported.

Kidney repair may not require stem cells
Harvard Stem Cell Institute (HSCI) researchers have a new model for how the kidney repairs itself, adding to growing evidence that mature cells are far more plastic than previously imagined.
Glucocorticoids may contribute to fetal brain changesGlucocorticoids have saved the lives of countless babies, but exposure may also have negative consequences. Excessive glucocorticoid levels may effect brain development, contributing to emotional problems later in life.
Gene in retinal development and motion sensing
Discovered gene aids in understanding the organization of parts of the eye and brain.

'Mini-neural computer' discovered in the brain
Dendrites, branch-like projections off of neurons, were once thought to be passive in the brain. But now research shows that dendrites actively process information, multiplying the brain’s computing power — a finding that could better explain some neurologic disorders.
Baby brains respond to another person's actions
Imitation may be the sincerest form of flattery for adults, but for babies it's the way they learn. As renowned people-watchers, babies observe others demonstrate how to do things and then copy their body movements.
Autism and language impairment genetically linked
Rutgers University scientists also find strong evidence of a genetic connection in areas of social skills and repetitive behaviors.
