Princeton University researchers have found that the roundworms Caenorhabditis elegans have a sure-fire method of ensuring a steady supply of a bacteria they eat — they grow their own. The worms carry the bacteria Escherichia coli along with them, and drop bacteria along the way to create thriving new bacterial colonies that the worms later return to "harvest" and eat.

Princeton University Professor of Mathematics John Mather, remembered as a "great mathematician" with a reserved and pleasant demeanor, died Jan. 28 of complications from prostate cancer at his home in Princeton. He was 74.

Since the Middle Ages, alchemists have sought to transmute elements, the most famous example being the long quest to turn lead into gold. Now, Princeton University theorists have proposed a different approach to this ancient ambition — just make one material behave like another. The researchers demonstrate that any two systems can be made to look alike, even if just for the smallest fraction of a second.

An influx of pollution from Asia in the western United States and more frequent heat waves in the eastern U.S. are responsible for the persistence of smog in these regions over the past quarter century despite laws curtailing the emission of smog-forming chemicals from automobile tailpipes and factories.

Theories developed at Princeton University led to the creation of time crystals reported in the journal Nature March 9 by two groups of researchers based at Harvard University and the University of Maryland. Time crystals feature atoms and molecules arranged across space and time and are opening up entirely new ways to think about the nature of matter. They also eventually may help protect information in futuristic devices known as quantum computers.

In many species, mating comes at the steep price of an organism's life, an evolutionary process intended to regulate reproductive competition. But Princeton University researchers report that males of the roundworm species Caenorhabditis elegans have doubled down with two methods of checking out after reproducing — a lethal gene activated after mating, and pheromones released by other males. The findings provide insight into how aging, longevity and population are naturally regulated for different species and sexes.

Princeton University has offered admission to 1,890 students, or 6.1 percent of the record 31,056 applicants for the Class of 2021, in what is the University's most selective admission process to date. Last year, the University's admission rate was 6.46 percent. The class size is expected to be 1,308 students for the Class of 2021.

John Pardon, a Princeton University professor of mathematics, has received a National Science Foundation Alan T. Waterman Award, which is the nation's highest honor for scientists and engineers younger than 35. The prize carries a five-year, $1 million grant. Pardon was recognized for "revolutionary, groundbreaking results in geometry and topology" that "have extended the power of tools of geometric analysis to solve deep problems in real and complex geometry, topology and dynamical systems."

Scientists know that two-star systems can support planets, but the question has remained whether an Earth-size terrestrial planet were orbiting two suns could it support life. A study in the journal Nature Communications has now found that an Earth-like planet orbiting two stars could be habitable if it were within a certain range from its two stars.

Princeton University-based researchers have found that machine-learning programs can acquire the cultural biases embedded in the patterns of wording, from a mere preference for flowers over insects, to discriminatory views on race and gender.

Princeton University has made public a preview version of a new design for its main website and is seeking comment from the University community and other visitors to the site. The preview site is at beta.princeton.edu.

Princeton University has reaffirmed a statement it made in 2015 expressing the hope that the then-upcoming U.N. Climate Negotiations in Paris would “lead to significant progress in promoting clean energy and other positive actions to address the environmental impacts of climate change.”

Princeton University awarded degrees to 1,268 undergraduates in the Class of 2017, three from former classes and 520 graduate students at its 270th Commencement Tuesday, June 6.
