Scientists have long debated how large-scale plant patterns such as the famous "fairy circles" of Namibia form and persist. Now, a new Princeton University-led study suggests that instead of a single overarching cause, large-scale vegetation patterns in arid ecosystems could occasionally stem from millions of local interactions among neighboring plants and animals. The work could explain many patterns throughout the world.

Princeton President Christopher L. Eisgruber and 47 other American college and university presidents today sent a letter to President Trump urging him to "rectify or rescind the recent executive order closing our country's borders to immigrants and others from seven majority-Muslim countries and to refugees from throughout the world." "If left in place," the letters says, "the order threatens both American higher education and the defining principles of our country."

Crowd wisdom tends to favor the most popular information, not necessarily the most correct — mass ignorance can cancel out a knowledgeable minority, resulting in the wrong answer becoming the most accepted. To improve wisdom-of-crowds surveys, Princeton University and the Massachusetts Institute of Technology researchers have developed what they call the "surprisingly popular" algorithm, wherein the correct answer is that which is more popular than people predict.

Two Princeton University studies are opening important new windows into understanding an untreatable group of common genetic disorders known as RASopathies that affect approximately one child out of 1,000 and are characterized by distinct facial features, developmental delays, cognitive impairment and heart problems. The findings could help point the way toward personalized precision therapies for these conditions.

Princeton University researchers have drastically shrunk the equipment for producing terahertz — important electromagnetic pulses lasting one millionth of a millionth of a second — to the size of a microchip. The simpler, cheaper generation of terahertz has potential for advances in medical imaging, communications and drug development.

A Princeton University-based study could prove significant in answering among the most enduring questions for ecologists: Why do species live where they do, and what are the factors that keep them there? The ranges of animals in the world's temperate mountain areas — often presumed to be determined by competition — may actually be determined more by temperature and habitat, the researchers report. The findings indicate that species living in temperate mountain habitats — particularly in the northern latitudes — could face even greater repercussions from climate change than previously thought.

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.

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.

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.

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."

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.
