Possible Space Travel and Exploration Means of the Future The recent turn of NASA toward the race back to the moon has been inspired in part by China's recent successes in space, their goals for lunar colonies and the designs of Japan and India add further encouragement. Looking at the new NASA moon probes, one may think of Steve Martin's movie "The Jerk" where he starts off in a small tarpaper shack only to end up with a larger version of the tarpaper shack after gaining and losing a fortune. The new manned moon probe looks like a scaled up Apollo program. Even the LEM is an updated version of the ungainly original one. NASA is hidebound by old forms that originated from the Nazi V-1 and V-2 programs. The International Space Station is now a good jumping off point to the moon, Mars, the planets and deep space; but it is only that. Lagrange effectively argued the point of gravitational places of equilibrium between two large masses.

Savoirs en multimédia Mitochondrial disease Mitochondrial disease is a group of disorders caused by dysfunctional mitochondria, the organelles that generate energy for the cell. Mitochondria are found in every cell of the human body except red blood cells and convert the energy of food molecules into the ATP that powers most cell functions. Mitochondrial diseases are sometimes (about 15% of the time)[1] caused by the mitochondrial DNA that affect mitochondrial function. Mitochondrial diseases take on unique characteristics both because of the way the diseases are often inherited and because mitochondria are so critical to cell function. The subclass of these diseases that have neuromuscular disease symptoms are often called a mitochondrial myopathy. Classification[edit] In addition to the mitochondrial myopathies, other examples include: Nota bene: Conditions such as Friedreich's ataxia can affect the mitochondria, but are not associated with mitochondrial proteins.

Canal-U Tracy Bale at SfN 2011 Why do some neurodevelopmental and neuropsychiatric diseases such as autism affect more boys than girls? Tracy Bale explains. At the Society for Neuroscience (SfN) meeting last week, Tracy Bale, Section Head in ‘Neural homeostasis’, talked to us about her research on how stress dysregulation underlies neuropsychiatric disease. It seems that there is truth behind the age-old belief that stress in pregnancy can harm the child. Tracy explains that stress experienced by the mother in early pregnancy can determine sex differences in how the offspring deal with stress. Tracy believes that these pathways could account for the sex biases in neurodevelopmental diseases such as autism, where boys are 4 times more likely than girls to be affected.
