On land, wooden artefacts such as shipwrecks may be destroyed through rotting, animals, or human action, but marine environments can prevent the biological, chemical, and mechanical changes that would cause an object to decay – preserving a rare time capsule to our past. However, when an ancient shipwreck is pulled from the water, the process of acidification can...

Innovative breakthrough promises to diagnose DNA rearrangement mutations Doctors are increasingly using genetic signatures to diagnose diseases and determine the best course of care, but using DNA sequencing and other techniques to detect genomic rearrangements remains costly or limited in capabilities. However, an innovative breakthrough developed by researchers at Virginia Commonwealth University Massey Cancer Center and the VCU Department of Physics promises to diagnose DNA rearrangement mutations at a fraction of the cost with improved accuracy. Led by VCU physicist Jason Reed, Ph.D., the...

Sponsored by Park SystemsJan 21 2021 Ferroelectrics found extensive uses in industrial applications because of their unparalleled electromechanical and electrical characteristics, for example, as actuators, sensors and capacitors [1], [2]. The suitability of ferroelectrics for modern communication technology is currently investigated by researchers, including 5G [3] and as active layers in photovoltaics [4, 5] among other applications [6]. Ferroelectricity is the consequence of an alteration in crystal symmetry during a phase transition. A sudden electrical polarization is introduced by an o...

It shows how a hexamer at the edge of the growing lattice gradually forms from... view more  Credit: Wouter Roos, University of Groningen The reproductive cycle of viruses requires self-assembly, maturation of virus particles and, after infection, the release of genetic material into a host cell. New physics-based technologies allow scientists to study the dynamics of this cycle and may eventually lead to new treatments. In his role as physical virologist, Wouter Roos, ...
