The digging and burrowing of prehistoric worms and other invertebrates along ocean bottoms sparked a chain of events that released oxygen into the ocean and atmosphere and helped kick-start what is known as the Great Ordovician Biodiversification Event, roughly 480 million years ago, according to new findings Johns Hopkins University researchers published in the journal Geochimica et Cosmochimica Acta.

The first article, published in Acta Biomaterialia, explains that cellular pathways for bone and cartilage formation can be activated in stem cells using inorganic ions.

Former biomedical engineering graduate student, Dr. Anna Kersey '23, was the lead author for the article published in Acta Biomaterialia and biomedical engineering graduate student Aparna Murali was the lead author for the follow-up article published in Advanced Science.

In a study recently published in Acta Materialia, the researchers took an in-depth look at the way the microstructure of Fe3Al develops because the ordered domains that form contribute to one of its key properties: superelasticity.

The research detailing this significant discovery is set to be published in the journal Acta Palaeontologica Polonica.
