First Actionable Clock That Predicts Immunological Health And Chronic Diseases Of Aging

About one in five will react to contact allergens, but some patients develop rashes and itching much faster than others. Previously the scientists were unable to explain why, but now researchers from the University of Copenhagen have outlined an entire new subgroup of allergic reactions which explains these early skin reactions. The new knowledge is vital to understanding the disease mechanisms in contact allergy.

Researchers from the University of Tsukuba in collaboration with Yamagata University scientists find that exposure to light with less blue before sleep is better for energy metabolism.

Extended exposure to light during nighttime can have negative consequences for human health. But now, researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep.

Characterized by the progressive loss of physiological capacity resulting in impaired functioning and susceptibility to diseases, the biological aging process at a cellular level has two key hallmark elements: telomere length (TL) shortening and cellular senescence. A variety of therapeutic methods aimed at reversing or slowing down this process continues to be investigated while a novel treatment shows promise – a specialized form of oxygen therapy that may be able to reverse the aforementioned biological markers of aging.

Keeping your brain active in old age has always been a smart idea, but a new study suggests that reading, writing letters and playing card games or puzzles in later life may delay the onset of Alzheimer's dementia by up to five years. The research is published in the July 14, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology.
