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 ...

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 ...

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. ...

A new antibiotic binding site found in the ribosome

A group of scientists from Russia, Germany and the United States, led by Skoltech scientists Ilya Osterman, Petr Sergiev, Olga Dontsova and Daniel Wilson from Hamburg University, has studied the mechanism by which tetracenomycin ...

Supercritical answer to waste oil found

Lubricating oils deteriorate and oxidize with use as well as accumulating particles from the engines and other machinery in which they are used. Ultimately, their effectiveness worsens and they begin to damage the components ...

Templating S100A9 amyloids on Aβ fibrillar surfaces revealed

A research team lead by Ludmilla Morozova Roche at Umeå University, Sweden, has provided the mechanistic insight into protein co-aggregation in Alzheimer's disease. The templating mechanism of S100A9 amyloids on Aβ fibrillar ...
