Researchers have discovered a potential biomarker for Alzheimer's disease diagnosis that may also serve as a therapeutic target. Examining cerebrospinal fluid samples from patients with cognitive impairment ranging from subjective impairment to a diagnosis of Alzheimer's disease, they found a shift in the profile of specialized liquid mediators from pro-resolving to pro-inflammatory.

Imaging at near-atomic resolution of a key immune protein commonly known as STING has revealed a previously unrecognized binding site that appears to be pivotal for launching immune attacks, scientists report. The findings could lead to new ways of manipulating STING to prompt stronger immune responses or stem its action in autoimmune diseases.

Implantable bioelectronics are now often key in assisting or monitoring the heart, brain, and other vital organs, but they often lack a safe, reliable way of transmitting their data to doctors. Now researchers have invented a way to augment implantable bioelectronics with simple, high-speed, low-power wireless data links using the body's naturally present ions.

Infants carry a vast assemblage of bacteria, viruses and fungi in their guts. Combined, these microbes make up a complex ecology known as the gut microbiome, which plays a major role in health and disease throughout life. The initial source of these billions of microbes is the mother's breast milk. Scientists have now used next-generation sequencing to investigate the breast milk microbiome from HIV positive women in Kenya.
