Researchers at UC Irvine have identified a trigger at the molecular level that marks the onset of memory decline in mice genetically engineered to develop brain lesions
Long distance messengers star in many heroic tales, perhaps the most famous being the one about the runner who carried the news about the victory of the Greeks over the Persians in the fateful battle of Marathon. A team of researchers at the Weizmann Institute of Science has now discovered how molecular messengers perform a crucial role in the ability of injured nerve cells to heal themselves.
Russian scientists have finally found a way to extend human lifespan by 20-30 years. Such sensational statement has been made by the head of a group of eco-population analysis at the Institute of biochemical physics of the Russian Academy of Sciences Valery Mamaev.
"Analysis of people"s mortality in various countries reveals that the aging process of people in many developed countries has altogether slowed down by approximately 15 years.
The Korea Times reports that researchers who successfully treated a paralysed patient with cord-blood stem cells are ready to start on a new round of trials as soon as their government gives permission. "We will conduct operations on two paralyzed patients as soon as the KFDA gives us the green light while the remaining two will also undergo stem cell therapy soon.

In a development that could alter the ethical landscape surrounding human embryonic stem (ES) cells, scientists have found that mouse ES cells can develop into oocytes in culture dishes. It is not yet clear whether the cells can be fertilized and develop into embryos. But if so, and if human ES cells turn out to have similar powers, such cells might allow researchers to get around some of the expense and ethical questions that arise from using donated eggs for therapeutic cloning experiments.
Purpose: u00a0Exploration of phospholipid balance, genetic expression, impact of toxicity and longevity through examination of fatty acid imbalances revealed through red cell lipid biopsy from Johns Hopkins with definitive medical approaches towards metabolic stability of lipid metabolism and longevity.
A team of US scientists have discovered that the adult brain is far more plastic and adaptable than thought previously. Using a pioneering technique Professor Karel Svoboda and colleagues from Cold Spring Harbor Laboratory in New York City studied the brain activity of living mice. The scientists firstly used genetic engineering to create mice with brain cells that produced a fluorescent green protein.
In an experiment that seems to be straight out of a science fiction novel, researchers have successfully created transgenic placentas. The researchers inserted a gene taken from a jellyfish into the fertilised egg of a rhesus monkey, creating a placenta in which the inserted gene functions in the same way that it normally does in the jellyfish.
Researchers from Aachen Technical College in Germany say that they are moving closer to their goal of being able to grow a new bladder from tissue taken from the patient's small intestine. To grow the bladder the researchers remove a small amount of tissue from the small intestine, strip off its mucosal layer, and cover it with tissue cultured from the patient's skin cells and grown on a matrix scaffold made from bovine collagen.
