New rules illuminate how objects absorb and emit light
Dec. 23, 2019
Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.
'Grow-and-prune' AI mimics brain development, slashes energy use
Dec. 19, 2019
In a pair of papers published earlier this year, researchers showed how to start with a simple design for an AI network, grow the network by adding artificial neurons and connections, then prune away unused portions leaving a lean but highly effective final product. Growing and pruning results in software that requires a fraction of the computational power, and so uses far less energy, to make equally good predictions about the world. Constraining energy use is critical in getting this kind of advanced AI—called machine learning—onto small devices like phones and watches.

Student's hybrid approach to machine learning leads to big win for healthcare
Nov. 6, 2019
Despite the dizzying array of smart technologies now defining modern life, at a deep level the programs running these gadgets come in two basic kinds: those that can steer a car and those that can finish a sentence. But in seeking smarter medical technologies (those that can detect a tumor), Princeton researchers have developed a third way forward that makes artificial intelligence work better for human health.
Senior thesis lights the way to promising new sensor technology
Nov. 4, 2019
Undergraduate researchers in electrical engineering have innovated on a new hybrid imaging technology, with potential applications in biomedical sensing, laboratory imaging and short-distance wireless communication.
Data centers, facing massive growth, get a boost from graduate students' research
Oct. 15, 2019
To keep up with the explosive demands of the modern Internet, data centers must process more power with greater efficiency in less space. Reducing the footprint of that demand lies at the heart of the matter for Ping Wang, graduate student in electrical engineering at Princeton, who was recently awarded a top prize at one of the world's leading conferences on power electronics.
Researchers work to protect smart machines from smart attacks
Oct. 11, 2019
Machines' ability to learn by processing data gleaned from sensors underlies automated vehicles, medical devices and a host of other emerging technologies. But that learning ability leaves systems vulnerable to hackers in unexpected ways, researchers at Princeton University have found.
Princeton announces initiative to propel innovations in quantum science and technology

Algorithms could stop an ‘internet of things’ attack from bringing down the power grid
Sept. 24, 2019
Last year, Princeton researchers identified a disturbing security flaw in which hackers could someday exploit internet-connected appliances to wreak havoc on the electrical grid. Now, the same research team has released algorithms to make the grid more resilient to such attacks.
