St. John's wort extract shows potent antiviral activity against SARS-CoV-2 and its variants

Scientists from Germany have recently identified Hypericum perforatum, a widespread herbal plant known as St. John's wort, as a potential antiviral agent against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study is published in the journal Pharmaceuticals.

Researchers reveal how not-yet-malignant cells “turn on” and become metastatic breast cancer

Mount Sinai researchers have discovered a previously unknown mechanism in which not-yet-malignant cells from early breast cancer tumors travel to other organs and, eventually, "turn on" and become metastatic breast cancer.

Quantitative MRI can detect subtle differences in the brain structure of premature babies

Premature babies who develop abnormalities like autism and cerebral palsy as teenagers have subtle differences in brain structure that can be detected on quantitative MRI (qMRI), according to a new study in the journal Radiology.

New insights into the link between EMFs, calcium and Alzheimer’s disease

For almost a quarter of a century, researchers have been studying and publishing on the effect of calcium on Alzheimer's Disease. Research has led to the development of the calcium hypothesis of Alzheimer's disease, which argues that Alzheimer's is caused by excessive intracellular calcium.

Moderate fitness levels produce significantly larger immune response in breast cancer survivors

A new study in breast cancer survivors has found that chemotherapy, while a critical part of breast cancer therapy, may also have some lasting dampening effects on natural immunity, but moderate fitness improvements can offer some protection against this effect.
