Dispossessions and race in the Americas
A group of Native Americans standing in a row. The trees behind are bare; it looks to be cold.

Belén Unzueta and her students looked at the enrollment cards the U.S. government gave Native Americans. It’s striking, because the cards list the blood quantum, she says.

Leading the charge: new research unveils the future of energy-efficent power delivery
Digital illustration of lithium ions passing through two-dimensional channels within a crystal structure

The rapid movement of lithium ions along the 2D vertical channels in the T-Niobium oxide (T-Nb2O5) thin film results in unique property changes and a chase transition. The blue and purple polyhedra show T-Nb2O5 lattices, without and with lithium, respectively. The bright green spheres represent lithium ions.

A plant-based, oral delivery of insulin regulates blood sugar levels similar to natural insulin
Two trays, one with four filled capsules, the other with green powder that will fill empty capsule shells.

With Daniell’s plant-based drug production and delivery platform, plant tissue is bombarded with biomedically important proteins, such as insulin, prompting the plant chloroplasts to take up the genes and express that protein. Harvested leaves can be freeze-dried and encapsulated, providing an affordable, shelf-stable means of delivery.
