New type of antibiotic discovered in soil in breakthrough for fight against drug-resistant superbugs

New type of antibiotic discovered in soil in breakthrough for fight against drug-resistant superbugs | Bioscience News - GEG Tech top picks | Scoop.it
Empty description
BigField GEG Tech's insight:
Scientists trawling through thousands of soil samples have discovered a whole new class of antibiotics capable of killing drug-resistant bacteria. The chemical, which has been called malacidin, appears to be non-toxic in humans and effective in tackling the hospital superbug MRSA, raising hopes that it could be used to develop a new treatment. Scientists say antimicrobial resistance - the ability of diseases to fight back against and ultimately become immune to known treatments - represents one of the greatest threats to humanity.

A cargo-sorting DNA robot - Science

A cargo-sorting DNA robot - Science | Bioscience News - GEG Tech top picks | Scoop.it
BigField GEG Tech's insight:

Single-stranded DNA robots can move over the surface of a DNA origami sheet and sort molecular cargoes. Thubagere et al. developed a simple algorithm for recognizing two types of molecular cargoes and their drop-off destinations on the surface (see the Perspective by Reif). The DNA robot, which has three modular functional domains, repeatedly picks up the two types of molecules and then places them at their target destinations. No additional power is required because the DNA robot does this by random walking across the origami surface.

Scientists discover unknown virus in ‘throwaway’ DNA | University of Oxford | Bioscience News - GEG Tech top picks | Scoop.it
A chance discovery has opened up a new method of finding unknown viruses.
BigField GEG Tech's insight:

In research published in the journal Virus Evolution, scientists from Oxford University’s Department of Zoology have revealed that Next-Generation Sequencing and its associated online DNA databases could be used in the field of viral discovery. They have developed algorithms that detect DNA from viruses that happen to be in the blood or tissue sample of the species studied. The research focused on fish genomes as an example, but the method could be used to identify viruses in a range of different species.

Fibril structure of amyloid-ß(1-42) by cryoelectron microscopy

http://science.sciencemag.org/content/early/2017/09/06/science.aao2825

BigField GEG Tech's insight:

Amyloids are implicated in neurodegenerative diseases. Fibrillar aggregates of the amyloid-β protein (Aβ) are the main component of the senile plaques found in brains of Alzheimer’s disease patients. We present the structure of an Aβ(1-42) fibril composed of two intertwined protofilaments determined by cryoelectron microscopy (cryo-EM) to 4.0 Å resolution, complemented by solid-state nuclear magnetic resonance (NMR) experiments. The backbone of all 42 residues and nearly all sidechains are well resolved in the EM density map, including the entire N terminus, which is part of the cross-β structure resulting in an overall “LS”-shaped topology of individual subunits. The dimer interface protects the hydrophobic C termini from the solvent. The unique staggering of the nonplanar subunits results in markedly different fibril ends, termed “groove” and “ridge,” leading to different binding pathways on both fibril ends, which has implications for fibril growth.
