'Semi-synthetic' bacteria churn out unnatural proteins

19-Jul-2019

Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made semi-synthetic organisms that have an expanded genetic code, allowing them to produce never-before-seen ...

Will your future computer be made using bacteria?

Scientists are making graphene easier and more environmentally friendly to produce

12-Jul-2019

In order to create new and more efficient computers, medical devices, and other advanced technologies, researchers are turning to nanomaterials: materials manipulated on the scale of atoms or molecules that exhibit unique properties. Graphene--a flake of carbon as thin as a single later of ...

Methane-consuming bacteria could be the future of fuel

Discovery illuminates how bacteria turn methane gas into liquid methanol

13-May-2019

Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic bacteria have long fascinated researchers. But how, exactly, these bacteria naturally perform such a complex reaction has been a mystery. Now an interdisciplinary team at Northwestern ...

New sensor detects rare metals used in smartphones

25-Apr-2019

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of researchers from Penn State developed the ...

"Molecular scissors" for plastic waste

15-Apr-2019

A research team from the University of Greifswald and Helmholtz-Zentrum-Berlin (HZB) has solved the molecular structure of the important enzyme MHETase at BESSY II. MHETase was discovered in bacteria and together with a second enzyme - PETase - is able to break down the widely used plastic PET ...

A dust-up: Microbes interact with harmful chemicals in dust

Microbes in household dust can break down harmful chemicals

15-Apr-2019

The dust that settles throughout our homes and offices almost always contains bits of chemicals that can cause problems for the human endocrine system, scientists say. But a new study indicates that the microbes we track into buildings--the microscopic bacteria and other microorganisms that ...

Bacteria could become a future source of electricity

28-Mar-2019

In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, researchers from institutions including Lund ...

Engineered microbe may be key to producing plastic from plants

08-Mar-2019

With a few genetic tweaks, a type of soil bacteria with an appetite for hydrocarbons shows promise as a biological factory for converting a renewable -- but frustratingly untapped -- bounty into a replacement for ubiquitous plastics. Researchers, like those at the University of ...

Natural substance as alternative to controversial glyphosate?

Novel unusual sugar from cyanobacteria acts as natural herbicide

05-Feb-2019

Researchers at the University of Tübingen have discovered a natural substance that could compete with the controversial herbicide glyphosate: The newly discovered sugar molecule synthesized from cyanobacteria inhibits the growth of various microorganisms and plants but is harmless to humans and ...
