  • Solutions to urban heat differ between tropical and drier climes

    In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world’s cities, heat island intensity can largely be explained by a city’s population and precipitation level, researchers reported in a paper published Sept. 4 in the journal Nature.

  • ‘She Roars’ podcast talks with Jo Dunkley about taking the universe's baby picture

    Astrophysicist Jo Dunkley talks in the latest episode of the “She Roars” podcast about studying the origins of the universe — and sharing her love of space with the public.

    Jo first came to Princeton as a postdoc in 2006, when she worked on data from the Wilkinson Microwave Anisotropy Probe (WMAP), a space telescope that took the universe’s earliest baby pictures. When she ran her code on that data, she was briefly the only person in the world to know the precise age of the universe. (Don’t worry, she quickly shared the news.)

  • Researchers reverse engineer the 'fireworks of life'

    Imagine standing in a lumberyard and being asked to build a house — without blueprints or instructions of any kind. The materials are all in front of you, but that doesn’t mean you have the first idea how to get from point A to point B.

    That was the situation facing the Princeton biologists who are building microtubules, the skeleton of the cell, from scratch.

  • Experiments explore the mysteries of 'magic' angle superconductors

    In spring 2018, the surprising discovery of superconductivity in a new material set the scientific community abuzz. Built by layering one carbon sheet atop another and twisting the top one at a "magic" angle, the material enabled electrons to flow without resistance, a trait that could dramatically boost energy efficient power transmission and usher in a host of new technologies.

  • Simons Foundation commits $20 million in quest to understand universe’s beginning

    What was the universe like in the moments after its inception?

    Princeton scientists will soon be better equipped to answer that question, thanks to a future commitment of $20 million made by the Simons Foundation. The funds will support five years of operations of the Simons Observatory, contingent upon the successful completion of the construction, which is currently underway in Chile’s Atacama Desert, at 17,200 feet in elevation. The official groundbreaking ceremony was held on June 30.

  • Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing

    Monday, Jul 1, 2019
    by Catherine Zandonella, Office of the Dean for Research

    As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics.

    Its fame stems from its strange properties – it is the only particle that is its own antiparticle – and from its potential to be harnessed for future quantum computing.

  • New campus-wide service will enhance access to research data

    Tuesday, May 14, 2019
    by Catherine Zandonella, Office of the Dean for Research

    With the goal of making the results of research and scholarship more accessible, Princeton will launch a new service to provide infrastructure and training to University researchers on how best to format and curate data in ways that facilitate long-term storage and discovery.
