Understanding where and in what quantities essential elements for life have existed on Earth's surface helps explain the ...

The COVID pandemic illustrated how urgently we need antiviral medications capable of treating coronavirus infections. To aid ...

Here we use cryogenic electron microscopy to determine the structure of TbAQP2 from Trypanosoma brucei, bound to either the substrate glycerol or to the sleeping sickness drugs, pentamidine or ...

How do we determine how healthy our food is? We know now that our nutrition shouldn't just be measured in calories, or even ...

This is an important study that combines replications of findings and novel detailed MRI investigations to assess the impact of environmental enrichment and maternal behavior on mice brain structure ...

As time goes by, our bodies change, you know, even the brain. A major change is how brain structure seems to shrink with age. Studies show that this happens at both large and small levels inside. You ...

Journey’s end. Kelly attacked the final structure, an elevator tower designed to raise the ship’s cargo from quay to conveyor. Rat-a-tat-a-tat-rat-a-whoofffFFFF. The walls of the intake elevator ...

The human glucose-6-phosphatase (G6Pase) catalyzes the hydrolysis of glucose-6-phosphate (G6P) in the endoplasmic reticulum lumen, the final step of both gluconeogenesis and glycogenolysis.

This includes unsaturated PFAS, whose chemical structure makes them easier to break down than so-called saturated PFAS. Examples of these chemicals include PFMeUPA and FTMeUPA, which are not yet ...
