Up to two decades before people develop the characteristic memory loss and confusion of Alzheimer’s disease, damaging clumps of protein start to build up in their brains. Now, a blood test to detect such early brain changes has moved one step closer to clinical use. Researchers from Washington University School of Medicine in St. Louis… Read more

A computer-assisted diagnostic procedure helps physicians detect the growth of low-grade brain tumors earlier and at smaller volumes than visual comparison alone, according to a new study by Hassan Fathallah-Shaykh of the University of Alabama at Birmingham, and colleagues. Additional clinical studies are needed to determine whether early therapeutic interventions enabled by early tumor growth… Read more

In life, timing is everything. Your body’s internal clock – the circadian rhythm – regulates an enormous variety of processes: when you sleep and wake, when you’re hungry, when you’re most productive. Given its palpable effect on so much of our lives, it’s not surprising that it has an enormous impact on our health as… Read more

A magnetic wire used to retrieve scarce and hard-to-capture tumor cells could turn out to be a rapid and effective tactic for early cancer detection, researchers at the Stanford University School of Medicine report. The wire, which is threaded into a vein, attracts special magnetic nanoparticles engineered to glom onto tumor cells that may be… Read more

A computer program that can comprehensively and cost-effectively determine differences in individuals’ blood types with more than 99 percent accuracy has been developed and validated by researchers. The investigators, from Brigham and Women’s Hospital, Harvard Medical School, and the New York Blood Center, leveraged the MedSeq Project – the first randomized trial of whole genome… Read more
