OCTOBER 24TH, 2023POSTED BY BRETT BEASLEY-NOTRE DAME A new device employs an innovative method for “listening in” on cells’ conversations. Scientists have long known that RNA (ribonucleic acid) acts as a messenger inside cells, translating DNA information to help cells make proteins. But recently, scientists have discovered that certain types of RNA venture outside the cell...

New ultrasound method could lead to easier disease diagnosis
by University of Sheffield Principle of acoustoelastic imaging of stresses.(A) Schematic showing that the principal stresses σ1 and σ3 change the speed of the vertically polarized shear waves. Here, an isotropic material subject to moderate stress is taken as an example. (B) An ultrasonic transducer with the axial direction (z) aligned with the principal direction x3 is used to...

Low-abundance biomarker detection platform for early disease diagnosis
by Anna Zarra Aldrich, University of Connecticut Lei’s technology advances traditional ELISA kits through the addition of two novel steps. Credit: Yu Lei Yu Lei, professor of chemical and biomolecular engineering, has invented a new platform that can perform high-sensitivity readings for a variety of disease biomarkers. In the 1970s, scientists invented the enzyme-linked immunosorbent assay (ELISA)....

A multishot lens less camera in development could aid in disease diagnosis
Researchers at Penn State are developing a new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object. The technology is expected to have used in lower-cost and faster disease diagnosis and the enhancement of optical microscopy and may lead to thinner cellphone technology. The research is supported by...
