Loss of stem cells correlates with premature aging in animal study

...l swoop. Essentially, these mice start their young adulthood with two strikes against them in terms of long-term tissue maintenance, and so, they subsequently age before their time.” With this new knowledge of how DNA repair, stem cells, and the aging process interconnect, Brown, first author Yaroslava Ruza...

Research finds music training 'tunes' human auditory system

...n improve one’s ability to learn tone languages in adulthood and level of musical experience plays a role in the degree of activation in the auditory cortex. Wong also is a faculty member in Northwestern’s Interdepartmental Neuroscience Program. The findings also are consistent with studies by Kraus and her...

Low levels of neurotransmitter serotonin may perpetuate child abuse across generations

...s. Abused females who became abusive mothers in adulthood had lower serotonin in their brains than abused females who did not become abusive parents, the research showed. Because the biological make up of humans and monkeys is quite similar, the findings from the monkey research could be valuable in unde...

Poor athletic performance linked to vitamin deficiency

Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

...connections. As the brain continues to develop in adulthood and as myelin is produced in greater and greater quantities, cholesterol levels in the brain increase and eventually promote the production of a toxic protein that attacks the brain. The protein attacks myelin, disrupts message transfer through the a...

Genes affecting blood pressure change as children become adults

... growing, hormones are raging and the stability of adulthood has not yet been reached," says Dr. Snieder. Those factors prompted him and his colleagues to look at what happens to blood pressure and related hemodynamics ?such as heart rate and how much blood the heart pumps with each beat ?near the beginning an...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

...ely spaced rings –?revealing rapid growth to young adulthood –?followed by six widely spaced rings corresponding with slower growth to full maturity by the end of its relatively long 13-year life. Its cranial crest would have reached its full size by then, thus providing an accurate model for scientists. The b...

For some young fish, early gene expression is a clear harbinger of fated lifestyle

...ical, and behavioral changes that prepare them for adulthood in open fresh and salty waters. In their innovative work, which is based on studying the gene expression profiles of hundreds of genes at a time in different fish populations, the researchers studied gene expression in two species--strains of the br...

Cloned stem cells prove identical to fertilized stem cells

...tero or at birth. The few clones that make it into adulthood are often plagued by bizarre health complications. This is one reason why scientists generally believe that attempting to clone a human being is morally reprehensible. But are the cloned embryo's stem cells beleaguered by the same defects? Studies...

New neurons take baby steps in the adult brain

...gain them, but in fact, new neurons do form during adulthood in all mammals, including humans, and become a working part of the adult brain in mice at the very least. In the first study to show how these "baby" neurons are integrated into the brain's existing networks, the Johns Hopkins researchers show that...

PLoS Medicine publishes first trial of effect of male circumcision on HIV infection

...area near Johannesburg, where male circumcision in adulthood is a common but not universal practice. The researchers offered young sexually active uncircumcised heterosexual men the chance to be circumcised and then monitored for HIV infection. The participants (3,274 men) were randomly allocated to two dif...

Suppressing growth hormone in early adulthood may prevent cancer

Suppression of growth...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

...three times as many hybrid kittens appear to reach adulthood as do purebred ones," the authors wrote. According to Pimm, native Florida panthers were "becoming famous" for an array of genetic abnormalities, including low sperm counts and heart defects. "It turns out that purebred kittens don't survive very we...

Cultural norms not unique to human societies

Signs of aging: Scientists evaluate genes associated with longevity

...rdinated up- or down-regulation from early to late adulthood would be those most critical to the vital biological process of aging. In addition, they reasoned that some of the genes that were differentially expressed between daf-2 mutants and controls would also be associated with longevity. Most strikingly, ...
