Novel hydrogel finds new aptamers, or "chemical antibodies," in days
One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short p.....»»
Targeting a coronavirus ion channel could yield new COVID-19 drugs
The genome of the SARS-CoV-2 virus encodes 29 proteins, one of which is an ion channel called E. This channel, which transports protons and calcium ions, induces infected cells to launch an inflammatory response that damages tissues and contributes t.....»»
Novel sustainable coupling technology proposed for carbon-to-acetylene process
The carbide-based carbon-to-acetylene (C2H2) process is a simple pathway to convert various sources of carbon into acetylene and carbon monoxide directly. However, the current industrial process based on calcium carbide (CaC2) is restricted by high e.....»»
