Stomach cancer is increasingly being detected earlier, raising hopes for survival

Doctors are increasingly detecting stomach tumors at an early stage, raising hopes for lifesaving treatment for one of the deadliest types of cancer. Stomach cancer, the disease that killed country music star Toby Keith in 2024, is typically difficult to catch early and tends to be discovered at an advanced stage when cancer cells have spread, researchers reported Saturday at Digestive Disease Week, a major international conference for doctors and researchers in gastroenterology, liver diseases and endoscopy.

Gravity Isn’t Real? This Theory Says It’s a Simulation

What if gravity isn’t a force, but a computation? In this episode, we explore Dr. Melvin Vopson’s groundbreaking theory that gravity emerges from the universe’s effort to compress and optimize information. Discover how this idea connects with simulation theory, quantum physics, and the future of reality.

See the Host Sun of Exoplanet K2-18b

While you won’t see a trace of this exoplanet or alien life, it’s easy to spot the red dwarf star that warms its surface.

You may never come face to face with your favorite rock star, but you can attend their concerts or listen to a music recording. Celestial bodies can be like that. Amateurs can’t see black holes, exoplanets, and accretion disks, but we can detect their presence by how they interact with their surroundings. At the very least we can picture them in our mind’s eye.

For example, a likely exoplanet orbits the 1st-magnitude star Pollux in the Gemini twins. It even has a name — Thestias. At public events, I point to Pollux and explain that a planet twice as massive as Jupiter orbits the red giant every 590 days. When it comes to novae, including the woefully-behind-schedule T Cor Bor, it’s fun to imagine the “single” star as a pair of tightly orbiting suns. One pilfers hydrogen from the other until enough material accumulates on the thief’s surface to detonate in a brilliant thermonuclear explosion. Voilà — a nova!

The Alien Cold War: Silent Competition Among Dormant Empires In A Dark Galaxy

What if the galaxy isn’t empty—but locked in a silent Cold War between ancient alien empires? This episode explores the Dark Forest Theory, Interdiction Bubbles, and what it means if our galaxy is shaped by dormant, watchful civilizations playing a long game of survival and subtle dominance.

New model can generate audio and music tracks from diverse data inputs

In recent years, computer scientists have created various highly performing machine learning tools to generate texts, images, videos, songs and other content. Most of these computational models are designed to create content based on text-based instructions provided by users.

Researchers at the Hong Kong University of Science and Technology recently introduced AudioX, a model that can generate high quality audio and music tracks using texts, video footage, images, music and audio recordings as inputs. Their model, introduced in a paper published on the arXiv preprint server, relies on a diffusion transformer, an advanced machine learning algorithm that leverages the so-called transformer architecture to generate content by progressively de-noising the input data it receives.

“Our research stems from a fundamental question in artificial intelligence: how can intelligent systems achieve unified cross-modal understanding and generation?” Wei Xue, the corresponding author of the paper, told Tech Xplore. “Human creation is a seamlessly integrated process, where information from different sensory channels is naturally fused by the brain. Traditional systems have often relied on specialized models, failing to capture and fuse these intrinsic connections between modalities.”

Galactic Beacons: Alien Signals Across Space And Time

It can be hard to hear a signal 100 miles away—so what does it take to build a beacon loud enough to be heard 100,000 light years away? In this episode, we explore galactic beacons: powerful transmissions that may teach, warn, or outlast the minds that made them.
