    Princeton faculty members Sarah Kocher and Andrew Leifer are among 60 researchers nationwide to receive 2019 New Innovator Awards from the National Institutes of Health (NIH). The awards are part of the NIH Common Fund’s High-Risk, High-Reward Research Program, which supports investigators pursuing highly innovative, high-impact biomedical and behavioral research.

  • Get moving! The mystery of animal group behavior

    It’s not uncommon to see a flock of birds, startled by some perceived threat, take to the air in a highly coordinated flight. Similar behavior can be observed in schooling fishes where each fish, mimicking the movement of its neighbor, turns, darts or zigzags away from a threat with uncanny precision. In both cases, it seems as if the respective groups — the flock and the school — are acting as a single, unified entity.

  • Genes, the social environment and adolescent smoking

    Adolescence is a time of dramatic change. It marks a period of significant physical transformation — such as the drive toward sexual maturity. But it can also be a time of considerable psychological change and social experimentation.

  • New research raises possibility of better anti-obesity drugs

    by Princeton University

    Effective weight-loss strategies call for eating less food, burning more calories — or ideally, both. But for the more than 90 million Americans who suffer from obesity, a disease that contributes to conditions ranging from heart disease to cancer, behavioral change is hard to accomplish or not effective enough, which is why scientists have long sought drugs that would help people shed pounds. Yet effective, long-lasting treatments have thus far eluded them.

  • Artificial intelligence detects a new class of mutations behind autism

    Many mutations in DNA that contribute to disease are not in actual genes but instead lie in the 99% of the genome once considered "junk." Even though scientists have recently come to understand that these vast stretches of DNA do in fact play critical roles, deciphering these effects on a wide scale has been impossible until now.

  • Racial bias associated with disparities in disciplinary action across U.S. schools

    Studies have shown that black students are subjected to higher disciplinary rates than whites, resulting in a number of negative life outcomes, including involvement in the criminal justice system.

    Using federal data covering 32 million students across 96,000 K-12 schools, researchers at Princeton University investigated the degree to which racial disparities in disciplinary action across the United States relates to county-level measures of racial bias.

  • Improvised dance embodies complexities of social decisions

    A work of art evolves from a series of decisions, as an artist combines brushstrokes, dance steps or musical notes to convey a feeling or idea. When a group of interacting dancers improvises a performance from a repertoire of possible movements, the dynamics of the artistic decisions become even more complex.
