Chemists Synthesize Two Simplified Forms of Superbug-Killing Antibiotic Teixobactin

Teixobactin eliminates MRSA, Mycobacterium tuberculosis, Streptococcus pneumoniae, Bacillus anthracis and other dangerous pathogens without encountering any detectable resistance. This digitally-colorized, scanning electron microscopic image depicts green-colored, spheroid-shaped MRSA bacteria, as they were in the process of being enveloped by a much larger, human white blood cell.

An international team of researchers led by the University of Lincoln, UK, has produced two simplified versions of teixobactin, a powerful natural antibiotic which many in the scientific community believe could lead to creation of the first commercially viable new antibiotic drug in three decades. Teixobactin eliminates MRSA, Mycobacterium tuberculosis, Streptococcus pneumoniae, Bacillus anthracis and other dangerous pathogens without encountering...

Tokuda et al apply electrical charges to morph liquid metal into 2D shapes. How the electric field creates deformation: (a) a liquid metal blob far from the electrodes and in absence of field is subject to no force; (b) deformation occurs when the blob is in contact with one of the electrodes and an electric voltage is applied across it; (c) deformation in this work as a 2D process.
