hits a roadblock
Increased expression of sirtuin proteins has been shown to enhance lifespan in several organisms. New data indicate that some of the reported effects may have been due to confounding factors in experimental design. Here, experts discuss the significance of these data for research into ageing. See Le...
Absence of effects of Sir2 overexpression on lifespan in C. elegans and Droso...
Overexpression of sirtuins (NAD+-dependent protein deacetylases) has been reported to increase lifespan in budding yeast (Saccharomyces cerevisiae), Caenorhabditis elegans and Drosophila melanogaster. Studies of the effects of genes on ageing are vulnerable to confounding effects of genetic backgrou...
The evolution of overconfidence
Confidence is an essential ingredient of success in a wide range of domains ranging from job performance and mental health to sports, business and combat. Some authors have suggested that not just confidence but overconfidence - believing you are better than you are in reality - is advantageous because ...
Oxytocin receptor gene (OXTR) is related to psychological resources [Psycholo...
Psychological resources - optimism, mastery, and self-esteem - buffer the deleterious effects of stress and are predictors of neurophysiological and psychological health-related outcomes. These resources have been shown to be highly heritable, yet the genetic basis for this heritability remains unknown....

Evolutionary biology: Chimp brains don't shrink
The human brain shrinks with age in what seems to be an evolutionarily new phenomenon, report Chet Sherwood of the George Washington University in Washington DC and his colleagues. They found that no parallel reduction in brain size seems to occur in our closest relative,
Evolution: Not so selfish
A prescription for how human cooperation evolved will provoke much-needed debate about the origins of society, finds Peter Richerson.
Aging of the cerebral cortex differs between humans and chimpanzees [Anthropo...
Several biological changes characterize normal brain aging in humans. Although some of these age-associated neural alterations are also found in other species, overt volumetric decline of particular brain structures, such as the hippocampus and frontal lobe, has only been observed in humans. However...
Spontaneous prosocial choice by chimpanzees [Psychological and Cognitive Scie...
The study of human and primate altruism faces an evolutionary anomaly: There is ample evidence for altruistic preferences in our own species and growing evidence in monkeys, but one of our closest relatives, the chimpanzee (Pan troglodytes), is viewed as a reluctant altruist, acting only in response...
The timing of mitochondrial DNA mutations in aging
Somatic mutations in mitochondrial DNA build up in aging tissues and are thought to contribute to physiological aging. Surprisingly, it is not known if these mutations occur early or late in life. A new study looks at mechanisms of accelerated mitochondrial aging in HIV-infected individuals treated ...
Motivating voter turnout by invoking the self [Psychological and Cognitive Sc...
Three randomized experiments found that subtle linguistic cues have the power to increase voting and related behavior. The phrasing of survey items was varied to frame voting either as the enactment of a personal identity (e.g., 'being a voter') or as simply a behavior (e.g., 'voting'). As predicted...
Increased risk of glucose intolerance and type 2 diabetes with statins
Statins are considered a 21st century panacea to the extent that some people propose they should be taken by everyone over 55 years of age.1 Convincing evidence shows that statins reduce all cause...
