Protecting brain cells with cannabinol      (via sciencedaily.com) 

Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer's, Parkinson's, and traumatic brain injury. Their findings reveal novel aspects of CBN's neuroprotective activity and demonstrate the clinical potential of CBN and value of studying its analogs.

Impact of aldehydes on DNA damage and aging      (via sciencedaily.com)     Original source 

Researchers have discovered the connection between aldehydes, organic compounds produced by cells as part of metabolic processes, and rapid aging. Their findings indicate a potential treatment for diseases that lead to accelerated aging as well as a means to counteract aging in healthy people by controlling exposure to aldehyde-inducing substances including alcohol, pollution, and smoke.

Pregnancy accelerates biological aging in a healthy, young adult population      (via sciencedaily.com)     Original source 

Pregnancy may carry a cost, reports a new study. The research shows that women who reported having been pregnant looked biologically older than women who had never been pregnant, and women who had been pregnant more often looked biologically older than those who reported fewer pregnancies.

Disparities in sleep health and insomnia may begin at a young age      (via sciencedaily.com)     Original source 

Children and teens from racial and ethnic minority groups are disproportionately affected by persistent insomnia symptoms that begin in childhood and continue through young adulthood, according to a new study. This study is one of the first to look at how childhood insomnia symptoms evolve over the long-term and investigate how the trajectory of insomnia differs between racial and ethnic groups.

RNA that doesn't age      (via sciencedaily.com)     Original source 

Certain RNA molecules in the nerve cells in the brain last a life time without being renewed. Neuroscientists have now demonstrated that this. RNAs are generally short-lived molecules that are constantly reconstructed to adjust to environmental conditions. The research group hopes to decipher the complex aging process of the brain and gain a better understanding of related degenerative diseases.

Functional capacity in old age is like an ecosystem that may collapse when disrupted      (via sciencedaily.com)     Original source 

In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning. It is therefore important to look at functioning as a whole and to take care of the different aspects of physical and mental well-being.

Blended antioxidant supplement improves cognition and memory in aged mice      (via sciencedaily.com)     Original source 

Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant improvements in spatial cognition, short-term memory, and mitigated age-related muscle decline. The study suggests that blended antioxidant supplements hold promise as a dietary intervention for health issues associated with aging.

New imaging method illuminates oxygen's journey in the brain      (via sciencedaily.com)     Original source 

A new bioluminescence imaging technique has created highly detailed, and visually striking, images of the movement of oxygen in the brains of mice. The method, which can be easily replicated by other labs, will enable researchers to more precisely study forms of hypoxia in the brain, such as the denial of oxygen to the brain that occurs during a stroke or heart attack. The new research tool is already providing insight into why a sedentary lifestyle may increase risk for diseases like Alzheimer's.

Familial Alzheimer's disease transferred via bone marrow transplant in mice      (via sciencedaily.com)     Original source 

Familial Alzheimer's disease can be transferred via bone marrow transplant, researchers show. When the team transplanted bone marrow stem cells from mice carrying a hereditary version of Alzheimer's disease into normal lab mice, the recipients developed Alzheimer's disease -- and at an accelerated rate.

Reverse effects of trauma? Older brain cells linger unexpectedly before their death      (via sciencedaily.com)     Original source 

Researchers report that mature oligodendrocytes -- the central nervous system cells critical for brain function -- cling to life following a fatal trauma for much, much longer than scientists knew. The findings suggest a new pathway for efforts to reverse or prevent the damage that aging and diseases such as multiple sclerosis cause to these important cells.
