Researchers gain new insight into Alzheimer's using organoids that resemble mini brains

In the majority of cases, dementia can be traced back to Alzheimer's disease. Its causes are not really understood yet. What is known is that plaques form from misfolded proteins and that there is an increase in neuronal cell death levels in the brain. However, the plaques don't necessarily go hand in hand with any symptoms.

Prokaryotic transport protein transports both left-handed and right-handed aspartate efficiently

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to share this preference.

New discovery transforms conventional microfluidics into open-space microfluidics

Microfluidics refers to the manipulation of fluids in microscale devices. Commonly called "labs on a chip," microfluidic systems are used to study and analyze very small-scale chemical or biological samples, replacing the extremely expensive and cumbersome instruments used for traditional biological analyses.
