Irvine, Calif., Jan. 11, 2021 - Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties of crystalline materials used in a variety of high-technology devices.
Employing newly developed electron microscopy techniques, researchers at the University of California, Irvine and other institutions have, for the first time, measured the spectra of phonons - quantum mechanical vibrations in a lattice - at individual crystalline faults, and they discovered the propagation of phonons near the flaws. The team s findings are the subject of a study published recently in

Irvine, Calif., Jan. 5, 2021 Scientists at the University of California, Irvine have developed a new deep-learning framework that predicts gene regulation at the single-cell level.
Deep learning, a family of machine-learning methods based on artificial neural networks, has revolutionized applications such as image interpretation, natural language processing and autonomous driving. In a study published recently in
Science Advances, UCI researchers describe how the technique can also be successfully used to observe gene regulation at the cellular level. Until now, that process had been limited to tissue-level analysis.
According to co-senior author Xiaohui Xie, UCI professor of computer science, the framework enables the study of transcription factor binding at the cellular level, which was previously impossible due to the intrinsic noise and sparsity of single-cell data. A transcription factor is a protein that controls the translation of genetic information from DNA t

“Integrity, integration, inclusivity, impact and innovation” are the watchwords of Drexel’s new 10-year strategic plan, which was released Dec. 17.
The two-year undertaking is summarized in a brief framework, called “Drexel 2030: Designing the Future,” that outlines the initiatives, values and goals that will guide Drexel through the anticipated challenges of the coming decade.
The plan was drafted against a backdrop of changing trends in higher education, specifically demographic declines in high school graduates and international students, and it was made more urgent over the past year by the closure of Hahnemann Hospital and the acquisition of St. Christopher’s Hospital for Children, the pivot to remote instruction, and nationwide calls for racial equity.
Ed Secretary quits, HE leaders decry attack on US Capitol
The United States Secretary of Education Betsy DeVos has resigned and US higher education leaders have reacted with horror and condemnation to the mob riot on Wednesday 6 January which breached the US Capitol, where Congressmen were meeting to certify the presidential election results, forcing them to run to shelter in fear of their lives.
Five people, including one law enforcement officer, died during or as a result of the invasion, as supporters of President Donald Trump disrupted the ceremony for certification of the election results, which, when resumed later, confirmed Joe Biden as president-elect, formally signalling the end of Trump’s hold on the reins of power.
