The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to a new study. The study establishes a mortality timer that reveals how long a cell has left before it dies, and may lead to new longevity treatments that could extend human lifespan. “Ageing is [...]
A new study has revealed that saclipins, a natural substance from edible cyanobacterium, enhances collagen and supports anti-ageing. Cyanobacteria, or blue-green algae, have existed for billions of years, adapting to a diverse range of environments. Their remarkable ability to photosynthesise and make their own food, as well as their adaptability across a variety of habitats, [...]
Levothyroxine, the second most commonly prescribed medication among older adults in the U.S., may be associated with bone loss, according to a new study. Levothyroxine, marketed under multiple brand names including Synthroid, is a synthetic version of a hormone called thyroxine and is commonly prescribed to treat the condition hypothyroidism, or underactive thyroid. In people [...]
Funding has been provided for a team of researchers to explore the potential of online therapy to improve cognitive health in older intensive care unit (ICU) survivors struggling with depression. Depression affects one-third of patients released from the ICU and is a risk factor for Alzheimer’s disease and related dementias. Researchers believe effective depression treatment [...]
A new study has shown that genetic traits influence the cellular composition of atherosclerotic plaques, which over time will affect the risk of such lesions to cause a stroke or heart attack. This new knowledge can be used to improve the risk assessment and treatment of patients with atherosclerosis in the future. Atherosclerosis is the [...]
High cardiorespiratory fitness is associated with better cognitive performance and lower risk of dementia long term, including in people with a genetic predisposition to dementia. Cardiorespiratory fitness (CRF) is the capacity of the circulatory and respiratory systems to supply oxygen to muscles and declines increasingly with age as skeletal muscle is lost. CRF declines by [...]
New research has identified several community-level factors that may increase people’s risk of experiencing cognitive impairment. In the study of 2,830 dementia-free US individuals aged 65 years and above, 23.2 per cent of participants were categorised as having mild cognitive impairment. People who lived in areas with higher neighbourhood disadvantage, higher air pollution, higher homicide [...]
The American Federation for Aging Research (AFAR) has announced sixteen recipients of the 2024 Glenn Foundation for Medical Research Postdoctoral Fellowships in Aging Research and the Glenn Foundation for Medical Research Grants for Junior Faculty. The Glenn Foundation for Medical Research Postdoctoral Fellowships in Aging Research support postdoctoral fellows who direct their research towards basic [...]
With the worldwide population ageing at an unprecedented rate, the prevention of age-related diseases has become a prominent issue. It is important to comprehensively and quantitatively evaluate the changes that ageing causes at the molecular level in the body. By doing so, it may be possible to pinpoint specific ageing factors and suppress age-related diseases. [...]
The ageing and failure of cells that occurs when one part of the body is damaged can spread to other organs, a study suggests. Scientists have shown for the first time that the deterioration of cells in a damaged liver can activate a process associated with ageing and impaired function, which then transmits to otherwise [...]
