    For the first time, researchers have directly visualized how speaking produces and expels droplets of saliva into the air. The smallest droplets can be inhaled by other people and are a primary way that respiratory infections like COVID-19 spread from person to person.

  • Novel drug could be a powerful weapon in the fight against malaria and toxoplasmosis

    Princeton researchers are making key contributions toward developing a promising new treatment for the widespread and devastating diseases toxoplasmosis and malaria.

    The Princeton scientists specialize in preparing the drug compound into a medicine that is both safe and effective for humans and able to reach its intended sites of action in the body in sufficient doses.

  • New tools catch and release cellular targets at the flip of a light switch

    A Princeton team has developed a class of light-switchable, highly adaptable molecular tools with new capabilities to control cellular activities. The antibody-like proteins, called OptoBinders, allow researchers to rapidly control processes inside and outside of cells by directing their localization, with potential applications including protein purification, the improved production of biofuels, and new types of targeted cancer therapies.

    Princeton’s vital research across the spectrum of environmental issues is today and will continue to be pivotal to solving some of humanity’s toughest problems. Our impact is built on a long, deep, broad legacy of personal commitment, intellectual leadership, perseverance and innovation. This article is part of a series to present the sweep of Princeton’s environmental excellence over the past half-century.

  • New study provides evidence for decades-old theory to explain the odd behaviors of water

    Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do when they freeze?

    Now a new study provides strong evidence for a controversial theory that at very cold temperatures water can exist in two distinct liquid forms, one being less dense and more structured than the other.

  • Researchers use electric fields to herd cells like flocks of sheep

    Princeton researchers have created a device that can herd groups of cells like sheep, precisely directing the cells’ movements by manipulating electric fields to mimic those found in the body during healing. The technique opens new possibilities for tissue engineering, including approaches to promote wound healing, repair blood vessels or sculpt tissues.

  • Astrophysicist Kunz receives NSF award for research and for establishing plasma physics summer school aimed at attracting underrepresented students to field

    Matthew Kunz, an assistant professor of astrophysical sciences at Princeton University and a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has been awarded a National Science Foundation (NSF) five-year grant to research magnetic fields throughout the early universe and to establish a summer school on plasma physics aimed at attracting women and underrepresented minorities to the field.
