Research led by Clifford Brangwynne, an assistant professor of chemical and biological engineering, has demonstrated that the nucleolus, an important cellular body, has a complex internal structure despite being made of liquid. The nucleolus serves as a control center for cellular growth and health.

Princeton University researchers will have an integral role in the Simons Observatory, a new astronomy facility established with a $38.4 million grant from the Simons Foundation. The observatory will investigate cosmic microwave background radiation to better understand the physics and structure of the universe.
Scientists from Princeton University and NASA have confirmed that 1,284 objects observed outside Earth's solar system by NASA's Kepler spacecraft are indeed planets. The researchers used an automated technique developed at Princeton that allows scientists to efficiently determine if a Kepler signal is caused by a planet. It is the largest single announcement of new planets to date and more than doubles the number of confirmed planets discovered by Kepler so far.
The first Princeton Research Day featured more than 150 undergraduates, graduate students and postdoctoral researchers presenting their work Thursday, May 5, at Frist Campus Center. The event highlighted research from the natural sciences, social sciences, humanities and the arts in formats including talks, poster presentations, performances, art exhibitions and digital presentations — all designed with the general public in mind.
The first analysis of Pluto's interaction with the ubiquitous space plasma known as the solar wind found that Pluto has some unique and unexpected characteristics that are less like a comet and more like larger planets.
Death rates have declined among children and young adults in the poorest counties in the United States, according to the study published in Science. The results should be particularly encouraging to policymakers engaged in projects aimed to promote public health, like anti-tobacco initiatives or food and nutrition programs.
Scientists from Princeton University and Uppsala University have identified a specific gene that within a year helped spur a permanent physical change in a finch species in response to a drought-induced food shortage. The findings provide a genetic basis for natural selection that, when combined with observational data, could serve as a comprehensive model of evolution.
A team including Princeton University researchers has found that tree species that can withstand stress to the water-transport system that carries water from the roots to the crown are less susceptible to drought and massive die-off. The findings could help forestry experts, especially in the American West, create early-warning systems and take precautionary steps to reduce a forest's vulnerability to drought.
Eight new projects, from novel ways to control mosquitoes to a telescope for studying the Big Bang, have been awarded funding through the Dean for Research Innovation Funds.
Princeton University researchers found that ocean currents can carry objects to almost any place on the globe in less than a decade, faster than previously thought. While good for microorganisms such as phytoplankton that are essential to the marine food web, it also means that plastic debris, radioactive particles and virtually any kind of litter can quickly become a problem in areas far from where they originated
