Imagine a material that can be stretched and pulled out of shape that not only returns to its original shape but also grows stiffer and stronger each time. University of Washington researchers have developed a new “strain learning” metamaterial. Inspired by how nature strengthens materials—like how bones repair themselves or how spider silk becomes stronger when stressed—this innovation could significantly impact industries that rely on durable, adaptable materials, especially medicine. Their work, “Strain learning in protein-based mechanical metamaterials,” has been published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).
Chemistry Professors Alshakim Nelson and Munira Khalil are among the 38 new members of the Washington State Academy of Sciences recognized for their "outstanding record of scientific and technical achievement and willingness to work on behalf of the Academy to bring the best available science to bear on issues within the state of Washington."
Alshakim Nelson Alshakim Nelson , UW associate professor of chemistry, has been named Molecular Engineering & Sciences Institute (MolES) Director of Education. Nelson replaces Christine Luscombe , professor of chemistry and materials science & engineering, who served in the role prior to her recent appointment as interim chair of the Materials Science & Engineering Department. Nelson will lead the Molecular Engineering (MolE) Ph.D. Program , an interdisciplinary graduate program housed in the UW Graduate School and administered by the Molecular Engineering & Sciences Institute.

Advances in synthetic biology and biomaterials are opening up exciting prospects for the distributed manufacturing of drugs, food products, and other commodities.
A team was led by Dr. Alshakim Nelson, an assistant professor of chemistry at the UW, and Dr. Hal Alper, a professor of chemical engineering at the University of Texas, developed a new method that combines the bioactivity of microbes and a 3D-printed, synthetic hydrogel "” a water-based gel structure "” to create desired chemical compounds. The products can vary from pharmaceuticals to nutraceuticals, alluding to the vast potential for this new finding.
Researchers in the lab of MolES faculty member and professor of chemistry Al Nelson along with collaborators at the University of Texas unveiled a new way to produce medicines and chemicals and preserve them using portable "biofactories" that are embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor's offices or even basic refrigeration makes it hard to access critical medicines and other small-molecule compounds.
