Harnessing the nano-tractor-beam like abilities of optical tweezers, researchers from the University of Melbourne, Australia, and Huazhong University of Science and Technology, China, developed an all-silicon nanoantenna to trap individual quantum dots suspended in a microfluidic chamber.

In a new pair of papers, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) explore ways for computers to help doctors make better medical decisions.

More than 80 percent of women living with a history of breast or ovarian cancer at high-risk of having a gene mutation have never taken the test that can detect it.

In this issue of JCI Insight, researchers at Cedars-Sinai Medical Center adapted a noninvasive retinal imaging approach to characterize amyloid-β deposition, the pathological hallmark of Alzheimer's disease, in the retinas of patients and healthy controls. This imaging enabled detection and quantification of amyloid-β, revealing increased deposits in Alzheimer's patients compared to controls. These results demonstrate the feasibility of this approach as a tool for earlier Alzheimer's diagnosis and intervention.

An international team of scientists, led by mathematicians from the University of Exeter's Living Systems Institute, have developed a ground-breaking new method that can identify regions of brain tissue most likely to generate seizures in people with epilepsy.

Simple odor identification tests may help track the progression of Alzheimer's disease before symptoms actually appear, particularly among those at risk.
