Research led by the School of Arts & Sciences’ Joshua Plotkin and Taylor Kessinger sheds light on the impact of social contexts and multilayered societies on promoting cooperative behavior.
Candida albicans is a species of yeast that is a normal part of the human microbiota but can also cause severe infections that pose a significant global health risk due to their resistance to existing treatments, so much so that the World Health Organization has highlighted this as a priority issue. The picture above shows a before (left) and after (right) fluorescence image of fungal biofilms being precisely targeted by nanozyme microrobots without bonding to or disturbing the tissue sample.

Nanorobotic system presents new options for targeting fungal infections
Researchers from Penn Dental and Penn Engineering have developed a nanorobot system that precisely and rapidly targets fungal infections in the mouth.
Recipients of the 2023 President’s Innovation Prize, team Sonura, five bioengineering graduates from the School of Engineering and Applied Science, have created a device that filters out disruptive environmental noises for infants in neonatal intensive care units. Their beanie offers protection and fosters parental connection to newborns while also supporting their development.

Safe and sound: Sonura supports newborn development by sequestering disruptive noise
A team of five recent graduates from the School of Engineering and Applied Science and recipients of the 2023 President’s Innovation Prize have developed a beanie that filters out harmful noises for infants in neonatal intensive care units.
Understanding the decline in racial disparities in COVID
The School of Arts & Sciences’ Irma Elo and Samuel Preston, with a collaborative team of researchers, assessed racial disparities in U.S. COVID-19 deaths, calling for continued efforts to better understand and implement targeted strategies for addressing health inequalities.

Social conformity in pandemics: How our behaviors spread faster than the virus itself
Researchers led by former postdoc Bryce Morsky and Erol Akçay of the School of Arts & Sciences have produced a model for disease transmission that factors in the effects of social dynamics, specifically, how masking and social distancing are affected by social norms.
Transistors replaced vacuum tubes in the mid-20th century. They were initially made of germanium and later silicon, leading to the development of integrated circuits containing millions to billions of transistors on a single chip. The Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) became the dominant type due to its smaller size, faster speed, and greater energy efficiency. Today, MOSFETs are essential components in modern electronic devices such as computers, smartphones, and power electronics.

Moore than meets the eye
Following the death of Gordon Moore, co-founder of Intel and a pioneer in computer processor chips, Penn Today spoke with the School of Engineering and Applied Science’s Benjamin C. Lee about Moore’s contributions to technology and the history and rapid evolution of chips.

Repairing fractured metals for more sustainable construction
Mining, refining, and processing metals commonly used in construction are estimated to contribute around three billion tons of CO2-equivalent emissions. Now, researchers have developed a new metal-healing technique that fully restores previously unrepairable metals, presenting sustainable options for manufacturers.
