2010 spike in Greenland ice loss lifted bedrock, GPS reveals

An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons – and large portions of the island's bedrock rose an additional quarter of an inch in response. That's the finding from a network of nearly 50 GPS stations planted along the Greenland coast to measure the bedrock's natural response to the ever-diminishing weight of ice above...

Beating superbugs with a high-tech cleanser

Scientists have developed an efficient, cost-effective liquid solution that fights antibiotic-resistant bacteria on hospital surfaces and keeps patients safe from life-threatening infections. It's easy to prepare, easy to apply, non-toxic -- and it will cost just a few dollars per...

Shampoo formulation puzzle solved

A research team has demonstrated quantitatively the science behind an anomaly in the surface tension of polyelectrolyte/surfactant mixtures. Their findings show that the dramatic increase in surface tension that affects the production of various pharmaceutical and cosmetic formulations is caused by the comprehensive aggregation of active ingredients. They have outlined a way to reload interfaces...

Slow road to stability for emulsions

Physical equilibrium, assumed to be almost instant, may take months or years for particles in oil-water mixtures. By studying the behavior of tiny particles at an interface between oil and water, researchers have discovered that stabilized emulsions may take longer to reach equilibrium than previously...

Boceprevir: Indication of added benefit for specific patients

The active ingredient boceprevir has been available since the middle of 2011 as a treatment for chronic hepatitis C of genotype 1. In an early benefit assessment pursuant to the "Act on the Reform of the Market for Medicinal Products" (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) has now examined to establish whether boceprevir offers added benefit in comparison...

New leads on mechanisms that confer virulence to E.coli-type bacteria

A team headed by scientists from the IRB Barcelona reports how the protein Ler, which is found in pathogenic bacteria, interacts with certain DNA sequences, thereby activating numerous genes responsible for virulence, which bacteria then exploit to infect human cells. Ler is present in pathogenic Escherichia coli strains, such as the one that caused a deadly infectious outbreak in Germany last...

On the road to creating an affordable master instrument

Violins made of wood treated with fungus need not hide their lights when compared to a Stradivarius, as a blind test has already demonstrated. However, these tonal masterpieces are only available as individually-made instruments. In order that these biotech violins may be manufactured in larger numbers, Empa researchers are currently working on optimizing and standardizing the fungal treatment.
