The inflatable concrete dome

June 11, 2014 3:51 pm | News | Comments

When concrete shells are constructed, they usually have to be supported by elaborate timber structures. This is one reason why such structures are now rarely built. In Austria, engineers have developed a new construction method that does not require any solid supporting structure at all. Instead, an air cushion is inflated below a concrete slab, bending the concrete and quickly forming a self-supporting shell.

Protein could put antibiotic-resistant bugs in handcuffs

June 10, 2014 7:38 am | News | Comments

Staph infections that become resistant to multiple antibiotics don't happen because the bacteria themselves adapt to the drugs, but because of a kind of genetic parasite they carry called a plasmid that helps its host survive the antibiotics. Plasmids are rings of bare DNA containing a handful of genes that are essentially freeloaders, borrowing most of what they need to live from their bacterial host.
