"Flowering" viruses to tackle harmful bacteria

Clusters of special viruses that eat harmful bacteria have been discovered that bloom into flower-like shapes.
And it is believed these new forms can boost their properties, both for finding and killing targeted bacteria and serving as scaffolding for other beneficial microorganisms and materials.
The viruses are called bacteriophages but are referred to by scientists as “phages” for short.
They are re-emerging as treatments for many forms of infection, because they can be programmed to target specific bacteria while leaving others alone.
Work in the field had dropped off after the introduction of penicillin in the middle of the last century.
But as antimicrobial resistance continues to erode the effectiveness of existing antibiotics, engineers and scientists are returning their attention to phages.
A group of researchers at Canada’s McMaster University in Hamilton, Ontario, discovered the flowering surprise while preparing slides to view under a powerful microscope.
They were surprised to see the phages had joined together into three-dimensional shapes that look like sunflowers, but only two-tenths of a millimetre across.
By joining together in this way made the phages 100 times more efficient than unlinked phages at finding elusive bacterial targets.

A new house has big ambitions – to be the world’s tiniest. The microscopic dwelling , made out of silicon, is in the style of the gingerbread house from the Hansel and Gretel Brothers Grimm fairy story.Even more incredible, the miniscule creation was built on the head of a winking silicone snowman.Both of them together are barely taller than the width of a human hair .The house measures just six microns wide by 10 microns long.A micron is 0.001 of a millimeterThe house and snowman were made by researcher Travis Casagrande at McMaster University in Hamilton, Ontario, Canada.When the pieces are paced next to a human hair under the microscope . the hair looks like a huge tree trunk in comparison.
