A protein that can mean life or death for cells

Each cell in an organism has a sensor that measures the health of its "internal" environment. This "alarm" is found in the endoplasmic reticulum (ER), which is able to sense cellular stress and trigger either rescue responses ...

Diet affects pesticide resistance in honey bees

Feeding honey bees a natural diet of pollen makes them significantly more resistant to pesticides than feeding them an artificial diet, according to a team of researchers, who also found that pesticide exposure causes changes ...

Study shows how proteins guide electrons to the right place

Cells need energy to function. Researchers at the University of Gothenburg can now explain how energy is guided in the cell by small atomic movements to reach its destination in the protein. Imitating these structural changes ...

Cell types in the eye have ancient evolutionary origins

Karthik Shekhar and his colleagues raised a few eyebrows as they collected cow and pig eyes from Boston butchers, but those eyes—eventually from 17 separate species, including humans—are providing insights into the evolution ...

Visualizing PET's degradation by bacterial enzymes

The rigidity, transparency and hardness of PET (Polyethylene Terephthalate) make it one of the most valuable plastics for the manufacture of plastic bottles, packaging and other single-use products. However, these characteristics ...

Molecular rulers for high-resolution microscopy

There is good news for researchers working with high-resolution fluorescence microscopy: Biocompatible molecular rulers are available for the first time to calibrate the latest super-resolution microscopy methods.
