What online video grounding asks of a machine Every second, a streaming video unfurls a story. In a world of surveillance feeds, live sports, and endless social clips, there’s a practical itch: can a computer listen to a spoken query like a human would and point to the exact moment in the stream where it…
Seasonal Mystery of Muon Showers When the atmosphere hums with the heat of July, a quiet chorus travels underground: muons raining down from the sky, born in cosmic-ray showers high above. The NOvA Collaboration, working at Fermilab with researchers from around the world, has been watching a peculiar twist in that chorus. The rate at…
The world of clinical trials often feels like a race to prove one word: effective. Yet patients don’t live in single moments of success—their lives are a stream of events: hospital visits, aches, hospital stays, and sometimes the final, terminal event. Traditional analyses tend to spotlight the first major event and then stop, as if…
The Unexpected Persistence of Heat Imagine a ripple spreading across a still pond. The initial disturbance dictates the shape and spread of the waves. Similarly, in the world of heat equations, the initial conditions—how temperature is distributed at the outset—heavily influence how heat diffuses over time. A new study from the Australian National University, led…
Medical imaging is undergoing a quiet revolution. For decades, radiologists have painstakingly traced the outlines of organs on MRI scans, a process that’s both time-consuming and prone to human error. But now, artificial intelligence is stepping in, offering the potential to automate this crucial task and vastly improve the speed and accuracy of diagnoses. The…
In a world racing toward smarter devices, the challenge isn’t just collecting data but turning it into quick, trustworthy decisions where they matter most. Imagine autonomous vehicles, delivery drones, or factory robots that must both feel their surroundings and decide what to do in the blink of an eye. A new study from a team…
In a world of endless scrolling, your feed isn’t just a sequence of videos or posts; it’s a living experiment. Recommender systems learn from what you click, watch, or skim, and they tune themselves to maximize engagement. But the side effect is a popularity bias: items that are already popular get more exposure, which makes…
A New AI for Mammograms: Speed, Accuracy, and Less Memory Breast cancer is a global health crisis, and early detection is crucial. Mammograms, those slightly uncomfortable but potentially life-saving X-rays, are a cornerstone of early detection. But interpreting mammograms is complex, time-consuming, and requires highly trained radiologists. That’s where artificial intelligence comes in — but…
Unveiling the Universe’s Secret Order: A Symphony of D-modules Imagine the universe as a vast, intricate musical score. Each note, each chord, represents a fundamental particle, a force, a fleeting interaction. The beauty, the coherence of the cosmos, lies in how these elements interweave, forming a harmonious whole. But what if this harmony isn’t random…
Machine learning models are powerful, but they’re often tripped up by complex, real-world data. What if we could teach AI to ask for help? A new study from Liverpool John Moores University proposes an “Augmented Reinforcement Learning” (ARL) framework that does just that: it incorporates human insights into the AI’s decision-making process. Lead researcher Sandesh…
