Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use. Now, researchers at Princeton University have drastically shrunk much of that equipment.

Researchers spent two years documenting the distribution of 70 bird species across the Himalayas in India and found that temperature and habitat predominantly determine the elevations where the birds live.

Princeton University and 16 other universities filed a friend-of-the-court brief Monday supporting a legal challenge to the Trump administration’s Jan. 27 executive order on immigration.

A new center is bringing together researchers from Princeton and Rutgers universities to apply computational modeling to the understanding of psychiatric diseases. The Rutgers-Princeton Center for Computational Cognitive Neuropsychiatry, which will open its doors this month, aims to improve the diagnosis of mental disorders, better predict their progression and eventually aid in developing treatments.

Assistant professor of African American studies, Keeanga-Yamahtta Taylor’s research on structural discrimination in housing led her to consider how Americans can move beyond inequality to build a society where people are treated fairly and not on the basis of racial stereotypes.

Two Princeton University studies are opening important new windows into understanding an untreatable group of common genetic disorders known as RASopathies that are characterized by distinct facial features, developmental delays, cognitive impairment and heart problems.

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.

The stone monuments of Italy’s Certosa di Bologna cemetery have stood for more than two centuries as symbols of peace and eternity. But even stone does not last forever. So Enrico Sassoni, a visiting postdoctoral research associate in Princeton’s Department of Civil and Environmental Engineering, is working to protect the marble monuments and even make them stronger.

Princeton President Christopher L. Eisgruber issued the statement to the University community on Sunday, Jan. 29, 2017.

This fall semester, Princeton students in the course “Contemporary Art: The World Picture” examined how large-scale art exhibitions challenge and transform the way we look at the world. A key component of the class was a fall break trip to Brazil to visit the 32nd São Paulo Bienal.

“Service is a central part of the Princeton experience,” said Kimberly de los Santos, the Pace Center’s John C. Bogle ’51 and Burton G. Malkiel *64 Executive Director. “In service we learn about ourselves, about the community and about how to make positive change in the world around us”.

By the age of 6, girls become less likely than boys to associate brilliance with their own gender. This could have an immediate impact on their interest level in activities and may have long-term effects, such as whether women feel confident pursuing careers in certain academic fields that “cherish brilliance,” according to a new study conducted by researchers at Princeton University, New York University and the University of Illinois at Urbana-Champaign.

Dean of the Faculty Deborah Prentice will take office as Princeton University’s provost on July 1, succeeding Provost David Lee. Lee has decided to return to full-time teaching and research after serving since 2013 as the University’s second-ranking officer.

Pollution from the controlled fires that burn across Brazil’s São Paulo state during the sugarcane-harvesting season has a negative impact on infant health nearby. But the health of those same infants likely benefits from the economic opportunities the fires bring to their parents.

A delegation of Princeton faculty members — led by President Christopher L. Eisgruber and including the University’s 2015 and 2016 Nobel laureates —took part in and led discussions on major global issues at the annual meeting of the World Economic Forum that concluded Friday, Jan. 20, in Davos, Switzerland.

Raising further questions about privacy on the internet, researchers from Princeton and Stanford universities have released a study showing that a specific person’s online behavior can be identified by linking anonymous web browsing histories with social media profiles.

As Professor Joshua Shaevitz piped a few drops of methanol into a 35 mm film canister, students plugged their ears with their fingers in anticipation of the imminent bang. The “Piezo Popper,” a small bottle rocket ignited by a piezoelectric spark, is one of the hands-on projects in Shaevitz’s freshman seminar, “The Science of Mythbusters.”

Meg Urry was the first tenured physics professor at Yale University and was often the only woman in her physics classes, including her graduate class at MIT, but she still heard a fellow student complain that women were unfairly given advantages over their male colleagues. “That’s when I realized there was something fishy going on,” she said. Urry spoke at the 2017 APS Conference for Undergraduate Women in Physics (CUWiP) Mid-Atlantic Regional Conference at Princeton University.

The bacteria that cause the life-threatening disease cholera may initiate infection by coordinating a wave of mass shapeshifting that allows them to more effectively penetrate the intestines of their unwitting victims, according to a study led by Princeton University.
