Published A new addition to the CRISPR toolbox: Teaching the gene scissors to detect RNA
(via sciencedaily.com) Original source CRISPR-Cas systems, defense systems in bacteria, have become a plentiful source of technologies for molecular diagnostics. Researchers have now expanded this extensive toolbox further. Their novel method, called PUMA, enables the detection of RNA with Cas12 nucleases, which naturally target DNA. PUMA promises a wide range of applications and high accuracy.
Published Transporting precious cargo using the body's own delivery system
(via sciencedaily.com) Original source Delivery systems in body continuously move materials between cells. Hijacking these systems allowed scientists to improve loading and delivery of therapeutic proteins. Biophysical principles could be used to enable more cost-effective loading of biological cargo into cell-derived delivery systems. Engineered molecules loaded up to 240 times more protein than other loading methods.
Published Producing hydrogen and fertilizer at the same time
(via sciencedaily.com) Original source This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Crystals from radioactive metal actinium
(via sciencedaily.com) Original source Researchers grew crystals containing actinium and illuminated them with X-rays to learn how the radioactive metal binds with other elements. That information could help design better cancer treatments.
Published A better way to make RNA drugs
(via sciencedaily.com) Original source RNA drugs are the next frontier of medicine, but manufacturing them requires an expensive and labor-intensive process that limits production and produces metric tons of toxic chemical waste. Researchers report a new, enzyme-based RNA synthesis method that can produce strands of RNA with both natural and modified nucleotides without the environmental hazards.
Published Scientists create computer program that 'paints' the structure of molecules in the style of Piet Mondrian
(via sciencedaily.com) Original source Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.
Published Nanoplastics and 'forever chemicals' disrupt molecular structures, functionality
(via sciencedaily.com) Original source Researchers have made significant inroads in understanding how nanoplastics and per- and polyfluoroalkyl substances (PFAS) -- commonly known as forever chemicals -- disrupt biomolecular structure and function. The work shows that the compounds can alter proteins found in human breast milk and infant formulas -- potentially causing developmental issues downstream.
