Researchers think small to make progress toward better fuel cells

A collaborative study describes how fuel cells, which use chemical energy to power cars and devices, can be developed to be more cost-effective and efficient in the long term.

A wearable new technology moves brain monitoring from the lab to the real world
Two people standing in a lab space, holding headbands.

Postdoc Arjun Ramakrishnan (left) and Penn Integrates Knowledge professor Michael Platt created a wearable EEG akin to a Fitbit for the brain, with a set of silicon and silver nanowire sensors embedded into a head covering like the headband seen here. The new technology led to the formation of a company called Cogwear, LLC.

A wearable new technology moves brain monitoring from the lab to the real world

Uncovering the roots of discrimination toward immigrants
A group of people waiting on a platform of a train station with sunlit windows and a train on the tracks.

Sambanis and his co-authors ran the experiment more than 1,600 times in train stations in 30 cities in both western and eastern Germany, with more than 7,000 bystanders unwittingly participating.

Uncovering the roots of discrimination toward immigrants

New research from political scientist Nicholas Sambanis finds that religion may matter more than ethnicity in how immigrants are treated, even if they comply with local social norms.

    A physical model for forming patterns in pollen

    Physicists have developed a model that describes how patterns form on pollen spores, the first physically rigorous framework that details the thermodynamic processes that lead to complex biological architectures.

    Up, up, and away
    BLAST telescope with Mark Devlin and students

    As the project manager of the $100 million Simons Observatory project, Devlin (center) is working to keep the numerous and disparate components of the project from falling behind due to pandemic-related shutdowns while recognizing that some delays and disruptions will be inevitable. His advice is to not “sweat the small stuff.” (Pre-pandemic image)

    Up, up, and away

    Mark Devlin and his team behind BLAST are about to embark on another scientific adventure in Antarctica, this time measuring how stars form in our galaxy.

    Colin Twomey studies how groups, both human and animal, make collective decisions. His research covers a variety of topics, including fish behavior and human color perception.

    How do individual decisions affect group decisions?

    Postdoctoral fellow Colin Twomey looks to fish behavior to explore the dynamic between individual and group decision-making.
