A new way to control microbial metabolism

Microbes can be engineered to produce a variety of useful compounds, including plastics, biofuels, and pharmaceuticals. However, in many cases, these products compete with the metabolic pathways that the cells need to fuel ...

Researchers finally grasp the work week of enzymes

Enzymes are used widely in our everyday lives. Like tiny soldiers, enzymes in washing powder work to dismantle fat stains from clothing, just as they are used to transform straw into bioethanol or act as miniature pharmaceutical ...

Using the power of microwaves to recycle plastics

Despite continued efforts to reduce plastic waste, only a fraction of it is recycled. For example, less than 30 percent of plastic waste is recycled in the EU. Some of it is exported to non-EU countries for treatment. The ...

Life under extreme conditions at hot springs in the ocean

The volcanic island of Kueishantao in northeastern Taiwan is an extreme habitat for marine organisms. With an active volcano, the coastal area has a unique hydrothermal field with a multitude of hot springs and volcanic gases. ...

New 3-D printing technique produces 'living' 4-D materials

Repairing and reusing plastics and delivering cancer drugs more effectively are only two of many of the potential applications a new 3-D/4-D printing technology might have, thanks to the pioneering work of a research collaboration ...

Bacterial protein impairs important cellular processes

Areas of skin that have been damaged by an injury are ideal niches for the concentration of Pseudomonas aeruginosa, a bacterium which impairs the healing process in tissue and creates favorable conditions for infections. ...

Observing changes in the chirality of molecules in real time

Some molecules can exist in two mirror-image forms, similar to our hands. Although such so-called enantiomers have almost identical physical properties, they are not the same. The fact that they behave to each other like ...

Light at the end of the nanotunnel for future catalysts

Using a new type of nanoreactor, researchers at Chalmers University of Technology, Sweden, have mapped catalytic reactions on individual metallic nanoparticles. Their work could improve chemical processes, and lead to better ...

Nitrous oxide emissions set to rise in the Pacific Ocean

The acidification of the Pacific Ocean in northern Japan is increasing the natural production rate of N2O, an ozone-depleting greenhouse gas. That's the finding of a study carried out jointly by scientists at EPFL, Tokyo ...
