Fine-tuning the color of light

A new sort of optical device allows engineers to change the frequencies of individual photons, putting new capabilities in engineers’ hands.

Can extreme melt destabilize ice sheets?

Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet’s capacity to store future meltwater – and increase the likelihood of future melt raising sea levels.

Jeffrey Ullman receives ACM Turing Award

Ullman shares the prize with long-time collaborator Alfred Aho of Columbia University. They are recognized for their influential work on compilers and algorithms, including their co-authorship of widely popular textbooks on these topics.

Famous Stanford coding course free online

Stanford tries a new model for online learning. A free version of a popular intro to coding course is being offered for the second time this spring. The secret ingredient was the largest group of teachers for a single class. You can teach too! Applications are open.

Assessing regulatory fairness through machine learning

Applying machine learning to a U.S. Environmental Protection Agency initiative reveals how key design elements determine what communities bear the burden of pollution. The approach could help ensure fairness and accountability in machine learning used by government regulators.

New StageCast tool facilitates online performances

Stanford theater directors, computer scientists and electrical engineers created a new tool to help performers who are located in different spaces come together in online performances.

Hybrid chips can run AI on battery-powered devices

In traditional electronics, separate chips process and store data, wasting energy as they toss data back and forth over what engineers call a “memory wall.” New algorithms combine several energy-efficient hybrid chips to create the illusion of one mega–AI chip.

Undersea origins of Earth’s mysterious Love waves

Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth’s upper layers together generate much of the world’s seismic waves. Decoding the faint but ubiquitous vibrations known as Love waves could yield insights about Earth’s storm history, changing climate and interior.

Computer model can predict COVID-19’s spread

A study of how 98 million Americans move around each day suggests that most infections occur at “superspreader” sites that put people in contact for long periods, and details how mobility patterns help drive higher infection rates among minority and low-income populations.

AI detects hidden earthquakes

Tiny movements in Earth’s outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden microquakes in the growing mountain of seismic data.

How earthquake swarms arise

A new fault simulator maps out how interactions between pressure, friction and fluids rising through a fault zone can lead to slow-motion quakes and seismic swarms.

Predicting wildfires with CAT scans

Engineers at Stanford have used X-ray CT scans, more common in hospital labs, to study how wood catches fire. They’ve now turned that knowledge into a computer simulation to predict where fires will strike and spread.

Predicting the slow death of a lithium-ion battery

A new model offers a way to predict the condition of a battery’s internal systems in real-time with far more accuracy than existing tools. In electric cars, the technology could improve driving range estimates and prolong battery life.

Seeing objects through clouds and fog

Using a new algorithm, Stanford researchers have reconstructed the movements of individual particles of light to see through clouds, fog and other obstructions.

Storing data on 2D metals

Researchers have invented a way to slide atomically-thin layers of 2D materials over one another to store more data, in less space and using less energy.

Artificial synapse works with living cells

Researchers have created a device that can integrate and interact with neuron-like cells. This could be an early step toward an artificial synapse for use in brain-computer interfaces.

A ‘veil of darkness’ reduces racial bias in traffic stops

After analyzing 95 million traffic stop records, filed by officers with 21 state patrol agencies and 35 municipal police forces from 2011 to 2018, researchers concluded that “police stops and search decisions suffer from persistent racial bias.”

Modeling social distancing’s impact

Biologist Erin Mordecai discusses different social distancing strategies, how long we may need to maintain them and the risk of a disease resurgence if precautions are lifted too early.

Bringing silicon computing power to the brain

A new device enables researchers to observe hundreds of neurons in the brain in real-time. The system is based on modified silicon chips from cameras, but rather than taking a picture, it takes a movie of the neural electrical activity.

Pat Hanrahan wins Turing Award

Hanrahan splits the prize with one-time mentor and Pixar colleague Ed Catmull. The pair’s work continues to transform film, video games, virtual reality and more.

Is search media biased?

In an audit of search media results for every candidate running for federal office in the 2018 U.S. election, Stanford scholars found no evidence of political bias for or against either party.

New algorithm trains AI to avoid bad behaviors

Robots, self-driving cars and other intelligent machines could become better-behaved thanks to a new way to help machine learning designers build AI applications with safeguards against specific, undesirable outcomes such as racial and gender bias.

Geomathematician John W. Harbaugh dies at 92

Harbaugh, former chair of the Department of Geology, was a foundational figure in mathematical geology and active in campus leadership. He died July 28 at age 92.

New theory explains earthquakes we can’t feel

Researchers have explained mysterious slow-moving earthquakes known as slow slip events with the help of computer simulations. The answer, they learned, is in rocks’ pores.
