The research, published today in Nature Aging, shows how profiles of proteins in the blood accurately predict dementia up to 15 years prior to clinical diagnosis. These are known as biomarkers, which are molecules found in […]

However, many users are interested in what happens under the hood either as a learning experience or to […]
A 1.9 solar mass neutron star candidate in a 2-year orbit
Abstract:We report discovery and characterization of a main-sequence G star orbiting a dark object with mass $1.90pm 0.04,M_{odot}$. The system was discovered via Gaia astrometry and has an orbital period of 731 days. We obtained multi-epoch RV follow-up over a period of 600 days, allowing us to refine the Gaia orbital solution and precisely constrain […]
