Finding this new stellar stream, named after Nyx, the Greek goddess of night, was made possible using machine learning tools and simulations of data collected by the Gaia space observatory.
Observations by the Atacama Cosmology Telescope suggest that the universe is 13.77 billion years old, and reveals how fast the cosmos is expanding.
As research on campus slowly restarts, those whose work requires field surveys, large-scale collaborations, or travel face additional challenges in bringing their research back online.
To an English scholar or avid reader, the Shakespeare Canon represents some of the greatest literary works of the English language. To a network scientist, Shakespeare’s 37 plays and the 884,421 words they contain also represent a massively complex communication network.
When most aspects of university life moved online because of COVID-19, so, too, did the thesis defense for Ph.D. candidates. Despite some challenges, the shift had unexpected benefits.
A new study describes how external forces drive the rearrangement of individual particles in disordered solids, enabling new ways to imbue materials with unique mechanical properties.
While instructional laboratories on campus are closed, students, faculty, and instructors are finding creative solutions for science, math, and engineering courses and projects.
Researchers develop a new model for how the brain processes complex information: by striking a balance between accuracy and simplicity while making mistakes along the way.
Combining theoretical insights with experimental results, physicists demonstrate a new design for optoelectronic devices that could help make optical fiber communications more energy efficient.
Researchers develop a physical model that describes the optimal amount of ‘memory’ of prior infections that bacteria should have in order to efficiently mount a successful immune response.
Stuart Kauffman of the Perelman School of Medicine comments on a study that proposed a missing scientific law identifying “universal concepts of selection” that drive evolution.
