Coherent Raman microscopy could be expanded through fusion of instruments and computers

Researchers review combination of instrumentation and computational approaches to coherent Raman scattering (CRS), enhancing signal amplification and breaking cross-section limits. Hyperspectral CRS offers potential for deciphering chemical compositions in complex environments, but requires algorithms for information extraction.

Multi-drug resistant organisms can be transmitted between healthy dogs and cats and their hospitalised owners

A study of over 2,800 hospital patients and their companion animals found that sharing multidrug-resistant organisms (MDROs) between pets and owners is possible. However, the rate of MDRO transmission from pets to humans was very low, suggesting that neither cat nor dog ownership is a major risk factor for hospital-acquired infections.

Investigating the effects on amide-to-ester substitutions on membrane permeability of cyclic peptides

Researchers from Tokyo Institute of Technology discovered that amide-to-ester substitutions can significantly improve cyclic peptides' membrane permeability, making them suitable for clinical and therapeutic applications. The study used enhanced sampling molecular dynamics simulations to unravel the mechanism behind this effect.
