Clearance of protein linked to Alzheimer's controlled by circadian cycle Posted: 10 Feb 2022 12:42 PM PST The brain's ability to clear a protein closely linked to Alzheimer's disease is tied to our circadian cycle, according to new research. The research underscores the importance of healthy sleep habits in preventing the protein Amyloid-Beta 42 (AB42) from forming clumps in the brain, and opens a path to potential Alzheimer's therapies. |
Calorie restriction trial reveals key factors in extending human health Posted: 10 Feb 2022 12:42 PM PST Decades of research has shown that limits on calorie intake by flies, worms, and mice can enhance life span in laboratory conditions. But whether such calorie restriction can do the same for humans remains unclear. Now a new study confirms the health benefits of moderate calorie restrictions in humans -- and identifies a key protein that could be harnessed to extend health in humans. |
