Alternative splicing plays a role in compensating for loss of gene function

Living organisms have a knack for persisting in the face of challenges. For instance, when genes malfunction, organisms may be able to compensate by activating redundant genes with similar functions, called paralogs.

Elevated level of α-synuclein aggregates in stool samples can indicate early form of Parkinson’s

The so-called isolated REM-sleep behavior disorder is a condition that can provide an indication of Parkinson's disease well in advance.

OHSU researchers confirm first-ever nonhuman primate model of Usher syndrome

Those with Usher Syndrome -- the leading hereditary cause for simultaneous deafness and blindness, for which there is no treatment -- may have a new reason for hope now that researchers have confirmed the first-ever nonhuman primate model of their disease.

Ingestible sensor could offer an alternative to invasive procedures used to diagnose motility disorders

Engineers at MIT and Caltech have demonstrated an ingestible sensor whose location can be monitored as it moves through the digestive tract, an advance that could help doctors more easily diagnose gastrointestinal motility disorders such as constipation, gastroesophageal reflux disease, and gastroparesis.

Mosaic RBD nanoparticles offer 100% protection against SARS-CoV-2 in animal model

A recent PNAS journal study has sought to address the above-stated drawback and developed a new strategy that involves a self-assembling scaffold of proliferating cell nuclear antigen (PCNA). This technique can develop nanoparticles containing evenly incorporated heterotypic antigens.
