This EurekAlert! release looks at some of the challenges facing the increasing number of research groups who are attempting to destroy cancer stem cells: “Many of the colon cancer cells that form tumors can be killed by genetically short-circuiting the cells’ ability to absorb a key nutrient, a new study has found. While the findings [...]

From TechNewsWorld: “During his homily this Easter, Pope Benedict argued that medical science, in trying to defeat death, is leading humanity toward likely condemnation. It’s a position at odds with the value of life, one that the Church will likely revise years from now, replaying the institution’s embarrassment over censoring Galileo. … If scientists are [...]

An interesting article: “In what turned out to be his final official engagement as CEO of Sirtris Pharmaceuticals, Christoph Westphal offered some key lessons in how to build a successful biotech company … It’s pretty amazing … in the last 20 years, we’ve gone from zero understanding of the genes that play a role in [...]

Via EurekAlert!: “Adoptive immunotherapy is targeted to situations when the immune system fails to detect a disease [such as cancer]. The adoptive immunotherapy strategy is to harvest T cells from the patient, engineer them to spot the disease and then send them back in, like police detectives with a reliable tip. A major drawback, however, [...]

Scientists proceed in their work by discovering a correlation and then picking apart the underlying mechanisms to find out why the correlation exists. In the field of aging research a great many as yet unexplained correlations exist, any one of which may point the way to important new knowledge. Take this for example: “Biological rhythms [...]

Possibly an example of overthinking the issue at the JET, but the section on Finot illustrates that our era does not enjoy a monopoly on rational thinking about extending the healthy human life span: “The beginning of the modern period in the pursuit of radical human enhancement and longevity can be traced to fin-de-siecle/early twentieth-century [...]

This paper outlines the overlap between the ways in which both processes of aging and eating too much lead to the loss of muscle mass and strength: “Sarcopenia, which is defined by the loss of skeletal muscle mass, predisposes skeletal muscle to metabolic dysfunction which can precipitate metabolic disease. Similarly, overnutrition, which is a major [...]

Spanish scientists “have generated artificial human skin by [tissue] engineering based on agarose-fibrin biomaterial. The artificial skin was grafted onto mice, and optimal development, maturation and functionality results were obtained. This pioneering finding will allow the clinical use of human skin and its use in many laboratory tests on biological tissues - which, additionally, would [...]

Life is getting better: “Human society has changed much over the last centuries and this process of ‘modernization’ has profoundly affected the lives of individuals; currently we live quite different lives from those forefathers lived only five generations ago. There is difference of opinion as to whether we live better now than before and consequently [...]

From the Telegraph, news of continuing incremental progress in understanding the mechanisms of regeneration in lower animals: “research into how Planarian worms can regrow body parts - including a whole head and brain - could one day make it possible to regenerate old or damaged human organs and tissues … We want to be able [...]
