Research opens the possibility of temporarily reversing aging in the immune system
August 15, 2011 by admin · Leave a Comment
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered a new mechanism controlling ageing in white blood cells. The research, published in the September issue of the Journal of Immunology, opens up the possibility of temporarily reversing the effects of ageing on immunity and could, in the future, allow for the short-term boosting of the immune systems of older people.

Research by UCLA’s Gene Block, Christopher Colwell provides new insights into sleep difficulties among older people
A new study of the brain’s master circadian clock known as the suprachiasmatic nucleus, or SCN reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

Buck Institute scientists note first observation of genome-wide shift kicked off at level of translation that extends lifespan
When researchers at the Buck Institute dialed back activity of a specific mRNA translation factor in adult nematode worms they saw an unexpected genome-wide response that effectively increased activity in specific stress response genes that could help explain why the worms lived 40 percent longer under this condition. The study, appearing in the July 6, 2011 edition of Cell Metabolism, highlights the importance of mRNA translation in the aging process. mRNA translation occurs after genetic messages have been transcribed in cells, when the encoded messages of genes are actually translated into functional proteins.
California scientists discover how vitamins and minerals may prevent age-related diseases

New research in the FASEB Journal demonstrates need for public health initiatives aimed at identifying, treating and taking seriously modest vitamin and mineral deficiencies
Bethesda, MDSevere deficiency of the vitamins and minerals required for life is relatively uncommon in developed nations, but modest deficiency is very common and often not taken seriously. A new research published online in the FASEB Journal (http://www.fasebj.org), however, may change this thinking as it examines moderate selenium and vitamin K deficiency to show how damage accumulates over time as a result of vitamin and mineral loss, leading to age-related diseases.

UC Riverside longevity study unearths surprising answers
RIVERSIDE, Calif. - Cheer up. Stop worrying. Don’t work so hard.
Good advice for a long life? As it turns out, no. In a groundbreaking study of personality as a predictor of longevity, University of California, Riverside researchers found just the opposite.
Aging, interrupted
February 22, 2011 by admin · Leave a Comment
LA JOLLA, CAThe current pace of population aging is without parallel in human history but surprisingly little is known about the human aging process, because lifespans of eight decades or more make it difficult to study. Now, researchers at the Salk Institute for Biological Studies have replicated premature aging in the lab, allowing them to study aging-related disease in a dish.

Scientists demonstrate that environmental lithium uptake promotes longevity
(Jena, Germany) Professor Dr. Michael Ristow’s team along with Japanese colleagues from universities in Oita and Hiroshima have demonstrated by two independent approaches that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. The research team presents its results in the online edition of the scientific publication European Journal of Nutrition which is now online (see hyperlink below).

Human model of rare genetic disease reveals new clues to aging process
Scientists from A*STAR’s Institute of Medical Biology (IMB) in Singapore and the University of Hong Kong’s Department of Medicine have produced the world’s first human cell model of progeria, a disease resulting in severe premature ageing in one in four to eight million children worldwide. This model has allowed them to make new discoveries concerning the mechanism by which progeria works. Their findings were published this month in the prestigious scientific journal, Cell Stem Cell (1).
Are positive emotions good for your health in old age?
January 19, 2011 by admin · Leave a Comment
The notion that feeling good may be good for your health is not new, but is it really true? A new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, reviews the existing research on how positive emotions can influence health outcomes in later adulthood.

SLU scientist says findings could reframe how to fight aging
ST. LOUIS A compound which acts in the opposite way as growth hormone can reverse some of the signs of aging, a research team that includes a Saint Louis University physician has shown. The finding may be counter-intuitive to some older adults who take growth hormone, thinking it will help revitalize them.
