Sorting and secreting insulin by expiration date

A study in the Journal of Biological Chemistry describes a new way to determine the age of insulin-storage parcels, known as granules, and sheds light on how their age affects their release into the bloodstream. The findings ...

How do bacteria build up natural products?

The active agents of many drugs are natural products, so called because often only microorganisms are able to produce the complex structures. Similar to the production line in a factory, large enzyme complexes put these active ...

Parasite research heats up

Apicomplexan parasites infect hundreds of millions of people around the world each year. Several species of apicomplexan parasites in the Plasmodium genus cause malaria, while another apicomplexan species, Toxoplasma gondii ...

Research team proposes technology for producing superplastic wire

Currently, low-alloy aluminum is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements ...

New substrate to assist milk contaminate detection

Scientists develop a novel and direct approach based on surface enhanced Raman spectroscopy (SERS) to detect the antibiotic tetracycline (TC) and pesticide dicyandiamide (DCD) contaminants in milk samples. This work was done ...

Researchers solve a 60-year-old puzzle about a superhard material

Skoltech researchers, together with their industrial colleagues and academic partners, have cracked a 1960s puzzle about the crystal structure of a superhard tungsten boride that can be extremely useful in industrial applications, ...

Scientists dissociate water apart efficiently with new catalysts

University of Oregon chemists have made substantial gains in enhancing the catalytic water dissociation reaction in electrochemical reactors, called bipolar membrane electrolyzers, to more efficiently rip apart water molecules ...

Carbon-loving materials designed to reduce industrial emissions

Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, are advancing gas membrane materials to expand practical technology options for reducing industrial carbon ...

Algae as living biocatalysts for a green industry

Many substances that we use every day only work in the right 3-D structure. Natural enzymes could produce these in an environmentally friendly way—if they didn't need a co-substrate that is expensive to produce to date. ...

Just add nano-materials for stronger, tougher diving fins

Adding microscopic nano-materials to carbon fibre composites has resulted in stronger, tougher fins for divers. A space material company teamed up with a market leader in the design and production of free-diving and spear-fishing ...

Fluorine enables separation-free 'chiral chromatographic analysis'

Researchers from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences recently developed a new platform for rapid chiral analysis, producing chromatogram-like output without the need for separation. ...
