Arginine slows amyloid buildup and improves brain outcomes in Alzheimer’s disease models

Arginine reduced amyloid beta aggregation in vitro and in both Drosophila and AppNL-G-F mouse models of Alzheimer’s disease, leading to fewer dense-core plaques and improved behavior. The study provides preclinical evidence that oral arginine may modulate amyloid pathology, although high dosing requirements and model limitations constrain human translation.

Study uncovers role of mechanical forces in human gastrulation

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

Oral arginine reduces amyloid buildup in Alzheimer’s models

Alzheimer's disease (AD), a progressive neurodegenerative disorder, is one of the leading causes of dementia worldwide, and currently has no definitive cure. Although antibody-based therapies that target amyloid β (Aβ) have recently been developed, their clinical effectiveness remains limited.

Study clarifies how spermine can guard against Alzheimer’s and Parkinson’s

Researchers at the Paul Scherrer Institute PSI have clarified how spermine - a small molecule that regulates many processes in the body's cells - can guard against diseases such as Alzheimer's and Parkinson's: it renders certain proteins harmless by acting a bit like cheese on noodles, making them clump together.

Maternal age drives embryo arrest independently of chromosomal errors

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 10, 2025, titled "Developmental arrest rate of an embryo cohort correlates with advancing reproductive age, but not with the aneuploidy rate of the resulting blastocysts in good prognosis patients: a study of 25,974 embryos."

Micro-RNA in sperm proves vital for human embryogenesis

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to the development of the embryo several days after conception. The findings, published in the journal Nature Communications, may in the long term contribute to better diagnosis and treatment of involuntary childlessness.
