Mass General Brigham study uncovers 16 novel Alzheimer's risk genes

Investigators from Mass General Brigham have conducted a multi-ancestry, whole genome sequencing association study of Alzheimer's disease and found evidence for 16 new susceptibility genes, expanding the study of Alzheimer's disease in underrepresented groups.

Genetic study demonstrates fat-selective weight loss with GLP-1 agonist use

Diabetes and obesity have become pressing health issues worldwide. Glucagon-like peptide-1 (GLP-1) receptor agonists, a class of medications widely used in the treatment of type 2 diabetes (T2D), have shown significant effectiveness in both lowering blood sugar levels and aiding weight loss due to their unique pharmacological mechanisms.

Study challenges role of BRCA1 mutation in prostate cancer initiation

Mutations in the BRCA1 gene that are either inherited (germline) or acquired (somatic) might not be key to the initiation of prostate cancer, as previously thought, suggests the first study of its kind, published online in the open access journal BMJ Oncology.

Higher 'bad' cholesterol levels may help Sardinia’s seniors live longer, study finds

Higher LDL cholesterol levels (≥130 mg/dL) were linked to longer survival in Sardinian nonagenarians, challenging the conventional belief that lower cholesterol is always better. However, very high cholesterol levels, particularly in women, did not show additional longevity benefits.

New imaging tool reveals the brain's role in cochlea sensitivity

The brain may play a role in helping the ear regulate its sensitivity to sound and compensate for hearing loss by sending a signal to a structure in the inner ear known as the cochlea, according to a study that was just published in the Journal of Neuroscience.
