How might we extract the tech-essential mineral lithium sustainably from seawater? Will doctors someday engineer super-immune T cells? How do dialects arise in language? Why do we forget?
The College of Arts and Sciences (A&S) has awarded seven totaling $1.25 million to faculty members pursuing critical developments in areas ranging from quantum materials to sustainable technologies to a philosophical theory of widespread sentience.
Now in its second year, the program’s goal is to encourage A&S faculty to engage in high-impact, boundary-pushing research with potential to secure external support. This year, 42 applications represented disciplines spanning the sciences, social sciences, arts and humanities.
“Much of what we take for granted today began as daring new concepts in the minds of imaginative scholars or scientists, so we want to encourage intrepid intellectual pursuits of Arts and Sciences faculty,” said Ray Jayawardhana, the Harold Tanner Dean of the College of Arts and Sciences, who conceived of the program along with the college’s leadership team. “New Frontier Grants provide the impetus and resources to pursue bold ideas, transforming concept into exploration, exploration into discovery, and sometimes discovery into application. The projects supported by these grants have the potential to fundamentally shift major areas, whether it’s paving the way for future quantum technologies, probing core questions of linguistic theory, or making sense of memory retrieval mechanisms.”
The grants were made possible by gifts from several donors, including Miriam Shearing ’56.
Two of the New Frontier projects focus on the ascendant field of quantum materials research, tying into Cornell’s initiative.
In “Understanding and Creating New Quantum Materials with Light on Ultrafast Timescales,” , the Joyce A. Yelencsics Rosevear ’65 and Frederick M. Rosevear ’64 Assistant Professor of physics and , the James A. Weeks Professor of Physical Sciences, will address one of the primary challenges in understanding quantum materials – their ultrafast characteristic timescales – by using technologies developed for particle accelerators to make femtosecond-scale “movies” of electronic and atomic motion, and, using the same approach, to even create entirely new quantum materials with light.
“To push the limits of future quantum technologies, it is essential that new methods are developed to not only understand quantum materials, but also to control and create new and potentially useful quantum states of matter,” Maxson said.
Funding from the New Frontier program will allow Shen and Maxson to bring together two of Cornell’s major strengths in usually disparate fields, accelerator physics and quantum materials. If successful, this project could serve as the nucleus for larger, campuswide efforts in ultrafast science.
Also pursuing objectives in quantum materials, , assistant professor of physics, and , the Dick & Dale Reis Johnson Assistant Professor of physics, will develop a new thermal microscope to image quantum states of matter that are invisible in conventional experiments, through their project “Imaging Heat Flow in Quantum Materials.”
“Quantum materials are rich with ’emergent’ particles that are under investigation both for their fundamental properties and for applications like quantum information processing,” Nowack said. “A central difficulty is that many of these particles are invisible to most experiments because they do not carry an electrical charge. However, these particles do carry heat.” This collaboration uses superconducting quantum interference devices (SQUIDS), which have exquisite magnetic sensitivity, to carefully measure magnetic signatures of intrinsic noise, Nowack said; from the magnitude of the noise, the particles’ temperature can be determined.
In a project aimed at sustainable technology, , associate professor of chemistry and chemical biology, will develop techniques for extracting the mineral lithium – a critical component of batteries, wind turbines, smart phones and many other devices – from seawater. While technological demand makes harsh mining of lithium from geological deposits unsustainable, the ocean contains approximately 230 billion tons of lithium, more than 11,000 times the quantity found in terrestrial deposits. “Lithium Seawater Extraction with Hybrid Molecular Receptor-Material Adsorbents” is a collaboration with , assistant professor of mechanical and aerospace engineering in the College of Engineering.
Other projects examine the mind and body in matters of memory, language, sentience and the immune system:
- “Prefrontal Cortical Control of Memory Retrieval”: and , professors of psychology, and , the Mary Armstrong Meduski ’80 Assistant Professor of psychology, will explore brain mechanisms of memory retrieval by using memory manipulation as a tool to answer a fundamental question: How does memory retrieval work and why does it sometimes fail? The research on memory manipulation will likely be useful in future treatments of Alzheimer’s disease, PTSD, and simply improving everyday memory performance.
- “Emergence of Dialects in Networks of Speakers with Random, Constrained Interactions”: , associate professor of linguistics, and , the James Gilbert White Professor of Physical Sciences, will use a hybrid computational and experimental strategy to study dialect emergence, aiming to experimentally probe core questions of sociolinguistic theory, such as: How inevitable are dialects? And how long do they persist? In addition to an increase in theoretical understanding, the results will inform machine learning systems that use linguistic signals to monitor social group dynamics or individuals’ health.
- “CD8+ T Cells with Innate Properties: Determining Their Prevalence, Mechanistic Basics, and Therapeutic Potential:” , associate professor of molecular biology and genetics, in a collaboration with , associate professor of immunology in the College of Veterinary Medicine, will study the novel aspects of mouse and human CD8+ T cells, which are a major component of the adaptive immune system. This project will focus on an unexpected and understudied aspect of CD8+ T cells: their ability to moonlight as innate immune cells. Better understanding of these powerful immune cells may ultimately help engineer human T cells, a cutting-edge tool in cancer therapy.
- “Reinventing Sentience: Panpsychism”: , associate professor of philosophy and Himan Brown Continuity Fellow for the Jewish Studies Program, will explore panpsychism – the theory of widespread, even generalized sentience – bringing together thought from philosophy, psychology, biology, neuroscience and AI research to examine the possibilities, defensibility, and repercussions of widespread sentience, and to establish Cornell as a place where groundbreaking intellectual research on the mind takes place.
