The study, conducted prior to COVID-19, has broad potential for pandemic responses
29-Sep-2020
A team of Duke Health scientists have identified biomarkers that accurately identify numerous viral infections across the clinical stages of disease, advancing a potential new way to guide treatment, quarantine decisions, and other clinical and public health interventions in the setting of ...
Tags made of flashing DNA let researchers tease apart dozens of molecules at once
16-Apr-2019
An imaging technique developed at Duke University could make it possible to peer inside cells and watch dozens of different molecules in action at once -- by labeling them with short strands of light-up DNA that blink on and off with their own unique rhythm. "The idea is everything has its own ...
Photonic crystal waveguide paves the way to build futuristic light-based computers
21-Nov-2018
Engineers at Duke University have demonstrated a device that can direct photons of light around sharp corners with virtually no losses due to backscattering, a key property that will be needed if electronics are ever to be replaced with light-based devices. The result was achieved with photonic ...
RNA changes mark old blood cells among new ones, foiling self-transfusions
22-Oct-2018
A Duke University research team has found a way to help sporting officials detect whether an athlete's blood has been doped by an infusion of their own stored blood. While tests have been developed to detect two of the three most common methods of dramatically boosting the oxygen-carrying ...

A new Duke University-led study has found widespread uranium contamination in groundwater from aquifers in 16 Indian states. The main source of the uranium contamination is natural, but human factors such as groundwater-table decline and nitrate pollution may be exacerbating the problem. Several ...

Researchers from Duke University, Massachusetts General Hospital and the International Centre for Diarrheal Disease Research in Dhaka, Bangladesh have used machine learning algorithms to spot patterns within communities of bacteria living in the human gut that no human would ever be able to pick ...

Biomedical engineers at Duke University have used a CRISPR/Cas9 genetic engineering technique to turn off a gene that regulates cholesterol levels in adult mice, leading to reduced blood cholesterol levels and gene repression lasting for six months after a single treatment. This marks the first ...

Invasive cells deploy a trick to break through tissues and spread to other parts of the body, researchers report. In a new study, 3-D time-lapse imaging of cellular "break-ins" in the transparent worm C. elegans reveals a fleeting, yet key structure in action. A single protrusion bulges out from ...
12-Oct-2017
Researchers at Duke University have turned bacteria into the builders of useful devices by programming them with a synthetic gene circuit. As a bacterial colony grows into the shape of a hemisphere, the gene circuit triggers the production of a type of protein to distribute within the colony that ...

Mutations tend to get a bad rap, and deservedly so. A single defect in our DNA can strip us of our sight, thicken our lungs with mucus, prompt us to bleed to death, weaken our muscles or fill our organs with tumors. But in certain situations, a mutation can actually be a source of strength. For ...
