(Phys.org)—In the complex, somewhat rarified world of interactions between various flavors of RNA, one elusive goal is to understand the precise regulatory relationships between competing endogenous RNA (ceRNA), microRNA (miRNA), small interfering RNA (siRNA) and messenger RNA (mRNA).

(Phys.org)—Although humans are a single species, not all genetic variation is shared between populations – and the ability to sequence our entire genome has allowed scientists to catalogue mutations that occur in one ethnic group alone. These so-called population-private mutations give researchers a unique window into recent human history. Recently, Read Full Article Here For…
(Phys.org)—As the batteries under development in today’s research labs are looking less like large blocks of metal and more like pieces of plastic wrap, their novel applications are coming closer to reality. One of the latest flexible batteries is thinner than a credit card, and could be integrated into various Read Full Article Here For…
One of the most common methods of creating the illusion of 3D is the autostereoscopic display, which is based on parallax: each eye is presented with a slightly different angle of a scene. Often this is done with many tiny microlenses, each projecting a small amount of light. Although this Read Full Article Here For…
(Phys.org)—Given that blood supply to the brain and spinal cord is fundamental to central nervous system (CNS) physiology and pathology, it’s not surprising that trauma and disease in spinal cord blood vessels and neurons lead to a range of neurodegenerative pathologies and other serious consequences. However, current imaging tools do Read Full Article Here For…
(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion (Na-ion) battery, which stands out because sodium is cheaper, non-toxic, and more abundant than lithium.

Article Abstract: (Phys.org)—As biotechnology and nanotechnology continue to merge, DNA-programmable methods have emerged as a way to provide unprecedented control over the assembly of nanoparticles into complex structures, including customizable periodic structures known as superlattices that allow fine tuning the interaction between light and highly organized collections of particles. Lattice structures have historically been two-dimensional…
Article Abstract: (Phys.org) —The ubiquitous van der Waals interaction – a consequence of quantum charge fluctuations – includes intermolecular forces such as attraction and repulsion between atoms, molecules and surfaces. The most long-range force acting between particles, it influences a range of phenomena including surface adhesion, friction and colloid stability. Typically a simple task when…
Article Abstract: (Phys.org)—Superconductivity – perhaps the leading example of emergent quantum behavior in matter – was discovered in 1911 but lacked theoretical explanation for almost five decades. In 1957, John Bardeen, Leon Cooper, and John Robert Schrieffer (BCS) developed a microscopic theory of superconductivity1 that came to be known as the BCS theory, which describes…
