New transporter for recycling of bacterial cell wall found

A transporter which some bacteria use to recycle fragments of their cell wall has been discovered by researchers at Umeå university, Sweden. They found that the transporter controls resistance to certain kinds of cell-wall targeting antibiotics. The transporter that Professor Felipe Cava and PhD student Michael Gilmore at Umeå university…

Physicists solve mystery of two-dimensional quasicrystal formation from metal oxides

The structure of two-dimensional titanium oxide brakes-up at high temperatures by adding barium; instead of regular hexagons, rings of four, seven and ten atoms are created that order aperiodically. A team at Martin Luther University Halle-Wittenberg (MLU) made this discovery in colaboration with researchers from the Max Planck Institute (MPI)…
