Protein quality control and mitochondria

Protein aggregates are toxic for mitochondrial function, and thus disrupt the supply of chemical energy to their host cells. An LMU team has characterized a protein complex that prevents the build-up of such deposits in the ...

Methods in belowground botany

Plant root systems play a crucial role in ecosystems, radically impacting everything from nutrient cycling to species composition. Despite their importance, scientists are just beginning to develop the tools to understand ...

Gold for iron nanocubes

One of the major challenges in nanotechnology is the precise control of shape, size and elemental composition of every single nanoparticle. Physical methods are able to produce homogeneous nanoparticles free of surface contamination. ...

Turning up the heat on pathogenic bacteria

Pathogenic bacteria come alive at the metabolic level when they enter the warmth of the human gut, firing up genes that encode toxins and other compounds harmful to our bodies. A KAUST-led study shows how a critical bacterial ...

Hybrid nanostructure steps up light-harvesting efficiency

To absorb incoming sunlight, plants and certain kinds of bacteria rely on a light-harvesting protein complex containing molecules called chromophores. This complex funnels solar energy to the photosynthetic reaction center, ...

Nuclear pore complex outer rings: No longer 'one size fits all'

In eukaryotic cells, the nucleus is walled off from the rest of the cell by the nuclear envelope. All transport into and out of the nucleus occurs via cylindrical channels called nuclear pore complexes (NPCs) that penetrate ...
