This is being called the most important discovery in the Valley of the Kings since King Tutankhamun.

Researchers at the University of Pennsylvania have demonstrated that gene therapy used to restore retinal activity to the blind also restores function to the brain’s visual center, a critical component of seeing.

The multi-institutional study led by Geoffrey K. Aguirre, assistant professor of neurology in Penn's School of Medicine, shows that gene therapy can improve retinal, visual-pathway and visual-cortex responses in animals born blind and has the potential to do the same in humans.

“The retina of the eye captures light, but the brain is where vision is experienced,” Aguirre said. “The traditional view is that blindness in infancy permanently alters the structure and function of the brain, leaving it unable to process visual information if sight is restored.

Researchers at the Picower Institute for Learning and Memory at MIT have, for the first time, reversed symptoms of mental retardation and autism in mice.

The mice were genetically manipulated to model Fragile X Syndrome (FXS), the leading inherited cause of mental retardation and the most common genetic cause of autism. The condition, tied to a mutated X chromosome gene called fragile X mental retardation 1 (FMR1) gene, causes mild learning disabilities to severe autism.

According to the Centers for Disease Control, FXS affects one in 4,000 males and one in 6,000 females of all races and ethnic groups. The prevalence of autism ranges from one in 500 to one in 166 children. There is no effective treatment for FXS and other types of autism.

Researchers at the University of Pennsylvania say that practicing even small doses of daily meditation may improve focus and performance.

Meditation, according to Penn neuroscientist Amishi Jha and Michael Baime, director of Penn's Stress Management Program, is an active and effortful process that literally changes the way the brain works. Their study is the first to examine how meditation may modify the three subcomponents of attention, including the ability to prioritize and manage tasks and goals, the ability to voluntarily focus on specific information and the ability to stay alert to the environment.

Topotecan, a cancer inhibitor, interacts with an important protein (TopoIB), causing a (cancer) cell to malfunction. The TopoIB protein is responsible for the removal of loops from DNA, which arise amongst other things during cell division.

The TopoIB protein binds to the DNA molecule, clamps around it and cuts one of the two DNA strands, after which it allows it to unwind and finally joins the broken ends together.

Until now it has been supposed that topotecan only causes the TopoIB protein to reside longer than normal on the DNA molecule, disturbing the cell division and damaging the (cancer) cell. But the researchers at the University of Delft have now discovered that adding topotecan also dramatically impedes the unwinding and that DNA loops accumulate as a result.

Dental enamel is the thin, outer layer of hard tissue that helps maintain the tooth's structure and shape while protecting it from decay.

While eating fruit is important part of a balanced diet, how you eat it may be ruining your teeth, says David Bartlett, BDS, PhD. Frequently consuming foods with a low pH (potential of hydrogen) value, such as fresh fruit, pickles, yogurt, honey, fruit juices and raisins can lead to irreversible dental erosion.

Eventually, because of repeated exposure to acid, the tooth’s enamel will lose its shape and color and as the damage progresses; the underlying dentin, (which is the tissue that makes up the core of each tooth), becomes exposed causing the teeth to look yellow.
