Tiny robots step closer to treating hard-to-reach parts of the body
Tiny remotely operated robots could be designed to diagnose and treat illness in hard-to-reach areas of the human body, research suggests. In tests, a swarm of robots measuring a few millionths of a metre long - about the size of a blood cell - were guided magnetically to sites in the stomach of rats.

Environmental factors may trigger lupus onset and progression
While genetics play a role in the development of Lupus, a systemic autoimmune disease that can attack any organ system in the human body, so do environmental triggers, such as particulates in air pollution and ultraviolet light, explains Gaurav Gulati, MD, a physician-researcher at the University of Cincinnati (UC) College of Medicine.

Biomarker may predict early Alzheimer's disease
Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a peptide that could lead to the early detection of Alzheimer's disease (AD). The discovery, published in Nature Communications, may also provide a means of homing drugs to diseased areas of the brain to treat AD, Parkinson's disease, as well as glioblastoma, brain injuries and stroke.

Understanding the Berlin patient's unexpected cure
A decade ago, the medical world was shocked when a patient in Berlin, Germany, had been declared free of HIV after receiving a stem cell transplant to treat cancer. Doctors have repeatedly tried to replicate the result, but this HIV cure has evaded other patients so far.

Could this protein protect people against coronary artery disease?
The buildup of plaque in the heart's arteries is an unfortunate part of aging. But by studying the genetic makeup of people who maintain clear arteries into old age, researchers led by UNC's Jonathan Schisler, PhD, have identified a possible genetic basis for coronary artery disease (CAD), as well as potential new opportunities to prevent it.
