- New mothers’ sleep loss linked to accelerated aging August 5, 2021When new mothers complain that all those sleepless nights caring for their newborns are taking years off their life, they just might be right. A year after giving birth, the 'biological age' of mothers who slept less than seven hours a night at the six-month mark was three to seven years older than those who […]
- Muscle protein that makes vertebrates more fit linked to limited lifespan August 5, 2021Researchers say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals. Their experiments working with mice and fruit flies, however, found that the gene for CaMKII also contributes to an evolutionary tradeoff: increased susceptibility to age-associated diseases, frailty and mortality.
- New genes linked to longer reproductive lifespan in women August 4, 2021Scientists have identified nearly 300 gene variations that influence reproductive lifespan in women. Additionally, in mice, they have successfully manipulated several key genes associated with these variants to extend their reproductive lifespan. Their findings substantially increase our knowledge of the reproductive ageing process, as well as providing ways to improve the prediction of which women […]
- Fine particulate air pollution associated with higher risk of dementia August 4, 2021Using data from two large, long-running study projects in the Puget Sound region -- one that began in the late 1970s measuring air pollution and another on risk factors for dementia that began in 1994 -- researchers identified a link between air pollution and dementia.
- Cryptic transcription, a novel phenomenon in mammalian stem cells, linked to aging August 2, 2021Researchers have discovered that a cellular phenomenon called cryptic transcription, which had been previously described and linked to aging in yeasts and worms, is also involved in mammalian aging. They also discovered a mechanism that triggers the phenomenon in mammals.
- Miniature brain models developed to study causes of Alzheimer’s disease and to test drugs in development August 2, 2021Researchers have developed a powerful miniature brain platform to study the mechanistic causes of Alzheimer's disease and to test dementia drugs in development.
- Early COVID-19 symptoms differ among age groups, research finds July 30, 2021Symptoms for early COVID-19 infection differ among age groups and between men and women, new research has found.
- Global dementia cases forecasted to triple by 2050 July 27, 2021Positive trends in global education access are expected to decrease dementia prevalence worldwide by 6.2 million cases by the year 2050. Meanwhile, anticipated trends in smoking, high body mass index and high blood sugar are predicted to increase prevalence by nearly the same number: 6.8 million cases.
- Scientists discover early signs of frontotemporal dementia in personalized cerebral organoids July 27, 2021Frontotemporal dementias are a group of fatal and debilitating brain disorders for which there are no cures. Researchers describe how they were able to recreate much of the damage seen in a widely studied form of the disease by growing special types of cerebral organoids in petri dishes. This form of the disease is caused […]
- Americans with higher net worth at midlife tend to live longer July 23, 2021In a wealth and longevity study to incorporate siblings and twin pair data, researchers analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.
