Mitochondria are the power plants of cells, manufacturing fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in cell suicide. Now, researchers at Washington University School of Medicine in St. Louis and the University of Padua-Dulbecco Telethon Institute in Italy have shown that mitochondria remarkably also orchestrate events that determine a cell’s future, at least in the embryonic mouse heart. The new study identifies new potential genetic culprits in the origins of some congenital heart defects.
Whitehead Institute researchers have discovered that the protein product of the gene MECP2, which is mutated in about 95% of Rett syndrome patients, is a global activator of neuronal gene expression.

A problem developing more efficient organic LED light bulbs and displays is that much of the light is trapped within the light-emitting diode, or LED. University of Utah physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle – wagon-wheel pasta – rather than spaghetti.
People with mental illness smoke at much higher rates than the overall population. But the popular belief that they are self-medicating is most likely wrong, according to researchers at the Indiana University School of Medicine. Instead, they report, research indicates that psychiatric disease makes the brain more susceptible to addiction.
Like the plastic caps at the end of shoelaces, telomeres protect — in their case — the interior-gene containing parts of chromosomes that carry a cell’s instructional material. Cancer cells are known to have short telomeres, but just how short they are from cancer cell to cancer cell may be a determining factor in a prostate cancer patient’s prognosis, according to a study led by Johns Hopkins scientists.
Researchers have found that the skeleton, acting through the bone-derived hormone osteocalcin, exerts a powerful influence on prenatal brain development and cognitive functions such as learning, memory, anxiety, and depression in adult mice.
