This month, we’re focusing on artificial intelligence (AI), a topic that continues to capture attention everywhere. Here, you’ll find the latest research news, insights, and discoveries shaping how AI is being developed and used across the world.

A new study from the UBC Sauder School of Business shows that AI-powered “digital streamers”—virtual salespeople who appear in livestreams to promote products—don’t perform as well as human streamers. In fact, they barely outperform having no streamer at all.
Vision happens when patterns of light entering the eye are converted into reliable patterns of brain activity. This reliability allows the brain to recognize the same object each time it is seen. Our brains, however, are not born with this ability; instead, we develop it through visual experience. Collaborating scientists at MPFI and the Frankfurt Institute for Advanced Studies have recently discovered key circuit changes that lead to the maturation of reliable brain activity patterns. Their findings, published in Neuron this week, are likely generalizable beyond vision, providing a framework to understand the brain’s unique ability to adapt and learn quickly during the earliest stages of development.
LIGO's improved sensitivity is showcased in a discovery of a black hole merger detected in January of this year. Scientists analyzing this signal were able to provide the best observational evidence yet for what is known as the black hole area theorem, an idea put forth by Stephen Hawking in 1971 that says the total surface areas of black holes cannot decrease.
When it comes to Earth’s climate system, water is often at the center of the story — whether it’s too much, too little or arriving at the wrong time. And while today’s climate models can tell us how much rain might fall or how humid the air might be, they often can’t answer the simpler, and perhaps more important, question: Where did this water come from? A new project led by Rice University and the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) is changing that. Backed by a grant from the National Science Foundation, the initiative — called SCI-SWIM, short for sustainable community infrastructure for stable water isotope modeling — will build a new and improved version of the Community Earth System Model (CESM), which can trace water across the entire planet from the clouds in the sky to the thick ice sheets deep underground.
