Study finds greater social jetlag linked to a later eating pattern

In a 14-day study of 101 healthy UK adults, greater social jetlag was associated with a later distribution of energy intake, particularly greater late-evening intake among women. The effects were modest, varied by sex and day type, and did not establish whether total daily energy intake differed between groups.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Thymulin curbs age-related inflammation and slows breast tumors in mice

Thymulin reduced age-associated inflammatory myeloid cells and slowed breast-tumor growth in aged mice by suppressing NF-κB signaling. The peptide also restored anti-PD-L1 responsiveness in aged mouse models, while human cell and tumor data supported an age-linked inflammatory myeloid profile.

Study links collagen peptides to improved bone health in runners

Collagen is a protein found in skin, hair, nails, tendons, cartilage, and bones. Our bodies naturally produce collagen using the foods we eat. But, in recent years, collagen peptides have gained popularity as a supplement to support joint, hair, skin, and gut health.

Motor abnormalities may predict multiple mental health disorders

Motor issues-such as coordination problems, motor slowing, or sudden, uncontrolled movements-have been recognized as signs of psychological disorders since the 1800s. How they map to mental health conditions, however, remains unknown.

Gut immune cells may improve multiple sclerosis treatment outcomes

B-cell depletion therapies, in which B cells of the immune system, which may drive disease activity in multiple sclerosis (MS), are temporarily removed, have contributed significantly to improved treatment for patients in recent years.

Frequent TV watching links to higher white matter lesion volume

ARIC researchers linked self-reported TV watching and occupational sitting in midlife with brain MRI measures obtained roughly 24 years later in 1,712 adults without dementia. Frequent TV watching was associated with greater white matter hyperintensity volume and lower volumes in several brain regions, while sitting at work was associated with lower white matter hyperintensity volume and larger selected cortical volumes.

UWM neuroscientist explores how estrogens regulate memory and brain function

Karyn Frick likes to think big. In college, she spent the summer after her junior year studying the neurobiology of memory in a lab at Johns Hopkins University. For hours at a time, Frick would watch rats scurry through mazes, entranced by their behavior.
