Protein Pathways: Mentally Stimulating Jobs Linked to Lower Risk of Dementia in Old Age

Certain proteins might provide clues to underlying biological mechanisms, say researchers. People with mentally stimulating jobs have a lower risk of dementia in old age than those with non-stimulating jobs, finds a study published by The...

New Research Shows Fibromyalgia Is Likely the Result of Autoimmune Problems

Fibromyalgia, or fibromyalgia syndrome, is a condition that causes aches and pain all over the body. New research has shown that many of the symptoms in fibromyalgia syndrome are caused by antibodies that increase the...

Important Clue to Rare Inflammatory Disease Found in Children Following COVID-19 Infection

Mount Sinai researchers have found an important clue to a rare but serious aftereffect of COVID-19 in children, known as multisystem inflammatory syndrome in children or MIS-C. The researchers reported that RNA sequencing of blood...

Traces of Dwarf Planet Ceres’ Icy Crust Found at Occator Crater

The study focused on Occator crater (left), which contains Ceres’ most prominent bright spots. The newly reported map (right) reveals higher concentrations of hydrogen than expected if the near sub-surface within Occator crater and...

Natural Compound Found in Fruit May Prevent and Treat Parkinson’s Disease

Farnesol is found in fruit, such as peaches. Johns Hopkins Medicine researchers say they have added to evidence that the compound farnesol, found naturally in herbs, and berries and other fruits, prevents and reverses brain...

Online Visualization Tool From NASA Provide a New Window on Rising Seas

Rising seas will exacerbate problems that coastal communities are already dealing with, including high-tide, or “nuisance,” floods. Inundated roadways like this one in Virginia are among the consequences of such floods. Credit: Aileen Devlin,...

Widespread Pain Linked to Increased Risk of Dementia and Stroke

Findings independent of age, sex, general health and lifestyle. Widespread pain is linked to a heightened risk of all types of dementia, including Alzheimer’s disease, and stroke, finds research published online in the journal Regional Anesthesia...

Public Health Experts: Global Eradication of COVID-19 Is Probably Feasible

Global eradication of COVID-19 probably feasible, and more so than for polio, say public health experts. Main challenges lie in securing high vaccine uptake and response to emergence of variants. The global eradication of COVID-19 is...
