WAVE – PARTICLE DUALITY



Wave–particle duality is the concept that every elementary particle or quantic entity exhibits the properties of not only particles, but also waves. It addresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects.

As Einstein wrote: "It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do."

TEIXOBACTIN PROMISE HOPE AGAINST ANTIBIOTIC RESISTANCE


Teixobactin is the first new class of antibiotic announced in decades.
Teixobactin inhibits cell wall synthesis by binding to a highly conserved motif of lipid II (precursor of peptidoglycan) and lipid III (precursor of cell wall teichoic acid).

The properties of this compound suggest a path towards developing antibiotics that are likely to avoid development of resistance.
