Computers Predict People’s Tastes in Art
A new Caltech study, appearing in the journal Nature Human Behaviour, shows that a simple computer program can accurately predict which style of paintings a person will like. Using Amazon’s crowdsourcing platform Mechanical Turk to enlist more than 1,500 volunteers to rate paintings in the genres of impressionism, cubism, abstract, and color field, the volunteers’ […]

Recording Brain Activity with Laser Light
A Caltech professor, in collaboration with researchers at the University of Southern California, has demonstrated for the first time a new technology for imaging the human brain using laser light and ultrasonic sound waves. The technology, known as photoacoustic computerized tomography, or PACT, has been developed by Lihong Wang, Bren Professor of Medical Engineering […]

Hungry Fruit Flies are Extreme Ultramarathon Fliers
In 2005, an ultramarathon runner ran continuously 560 kilometers (350 miles) in 80 hours, without sleeping or stopping. This distance was roughly 324,000 times the runner’s body length. Caltech scientists have discovered that fruit flies can fly up to 15 kilometers (9 miles) in a single journey—6 million times their body length, or the equivalent […]

Reading Minds with Ultrasound: A Less-Invasive Technique to Decode the Brain’s Intentions
Mapping neural activity to corresponding behaviors is a major goal for neuroscientists developing brain–machine interfaces (BMIs): devices that read and interpret brain activity and transmit instructions to a computer or machine. Though this may seem like science fiction, existing BMIs can, for example, connect a paralyzed person with a robotic arm; the device interprets the […]

The Golden Age of Social Science
Some of the most challenging problems facing our world, such as the COVID-19 pandemic, require not just one field of expertise but a unified interdisciplinary approach. Or so explains a team of social scientists at Caltech in a new report published in the Proceedings of the National Academy of Sciences (PNAS). Likening the report to […]

“Nuclear Physics”: Imaging into the Heart of a Cell
Nestled deep in the nucleus of each of your cells is what seems like a magic trick: Six feet of DNA is packaged into a tiny space 50 times smaller than the width of a human hair. Like a long, thin string of genetic spaghetti, this DNA blueprint for your whole body is folded and […]

What is Personality?
In a new paper, titled “Personality beyond taxonomy,” published in the journal Nature Human Behaviour, Caltech researchers from the disciplines of neuroscience, psychology, and philosophy discuss the long-standing question: What is personality? Whereas most studies measure personality in various ways, they are often ambiguous about what personality really is: Is it in the behaviors themselves […]

Proving a Link Between Chronic Alcohol Exposure and Impaired Inhibitory Function
The GABAB receptor (GABABR) agonist baclofen has been used to treat alcohol and several other substance use disorders yet how exactly it works remains unclear. Professor Tifei Yuan, a Tianqiao and Chrissy Chen Institute for Translational Research project lead and Principal Investigator at Shanghai Mental Health Center recently published an online paper titled, “Reduced Motor […]
