MultiGen: Level-Design for Editable Multiplayer Worlds in Diffusion Game Engines

Think of a video game that doesn’t just run on code, but is “dreamed up” in real-time by an AI—much like how AI generates videos or images today. While this technology (known as a Diffusion Game Engine) is incredibly exciting, it has long faced two major hurdles: you couldn’t easily “edit” the world once it was generated, and you couldn’t play in that world with friends because the AI couldn’t keep the environment consistent for everyone at once.

Traditional AI game engines work like “next-frame predictors.” They look at what’s happening right now and guess what the very next split-second should look like. Because they have a short memory (a “context window”), the world often feels like a shifting dream—turn around, and the door you just walked through might have disappeared or changed color. This makes it impossible to design a specific “level” or play with others, as the AI can’t keep a steady map in its head.

Why organisms are more than machines

We are living in the age of maximum AI hype: A superintelligence that surpasses humanity is going to emerge at any moment, according to the most breathless corners of the tech world.

There are basic technical grounds to be skeptical of that claim, but beyond that, a much deeper issue lies at the boundary between science and philosophy: What makes life different from non-life? Why is a rock inert and insensate, while even the simplest cell manifests open-ended activity in the relentless pursuit of staying alive? Since the only systems that indisputably display intelligence are alive, if we can’t understand life, we’re probably missing something essential about intelligence.

Sixty years ago, an influential but little-known philosopher named Hans Jonas gave a potent, creative, and radical answer to this question of what makes life different from non-life. In the decades since, the power and reach of his perspective have gained traction. Today, for a growing group of researchers — in fields ranging from neuroscience to the physics of complex systems — Jonas has become an incisive voice arguing forcefully that organisms are more than just machines, and minds are more than just computers.

Trends in Complementary and Alternative Medicine Use Among US Youths

Complementary and alternative medicine use among US children rose from 4.6% in 2007 to 17.7% in 2022, especially yoga and meditation, with the biggest increases in younger age groups.

This cross-sectional study estimates the prevalence of complementary and alternative medicine use among US youths aged 4 to 17 years in 2007, 2012, and 2022 overall and by sociodemographic factors.

Creating less trippy, more therapeutic ‘magic mushrooms’

Psilocybin—the psychoactive compound in “magic mushrooms”—is gaining scientific attention for its potential in treating neuropsychiatric conditions including depression, anxiety, substance use disorders and certain neurodegenerative diseases. However, its hallucinogenic effects may limit broader therapeutic applications. Researchers publishing in the Journal of Medicinal Chemistry synthesized modified versions of psilocin, the active form of psilocybin, that retained its activity while producing fewer hallucinogenic-like effects than pharmaceutical-grade psilocybin in a preliminary study in mice.

“Our findings are consistent with a growing scientific perspective suggesting that psychedelic effects and serotonergic activity may be dissociated,” says Andrea Mattarei, a corresponding author of the study. “This opens the possibility of designing new therapeutics that retain beneficial biological activity while reducing hallucinogenic responses, potentially enabling safer and more practical treatment strategies.”

Mood disorders and some neurodegenerative diseases, such as Alzheimer’s disease, involve imbalances of the neurotransmitter molecule serotonin, which helps regulate mood and other brain functions. For decades, scientists have been investigating the therapeutic use of psychedelics such as psilocybin on serotonin-signaling pathways. However, the hallucinations that can accompany these drugs may make people wary of taking them, even if there is a medical benefit.

Persistent Sex Disparities in Pre‐Hospital Delay Among Patients With STEMI Despite Overall Improvements: Findings From the Chinese Cardiovascular Association Chest Pain Center Registry

Despite overall improvements, women with STEMI in China still face longer pre-hospital delays than men, especially in rural areas. The gap is driven mostly by delayed EMS calls. Cardiology.

Chronic Rhinosinusitis Tied to Increased Cancer Risk

Chronic rhinosinusitis may be linked to an increased risk for cancer, according to a study of patients in Asia.

The study found that chronic rhinosinusitis was linked to an 18% increased risk for cancer in Korean patients and a 63% increased risk for cancer in patients from Japan. The results provide the first large-scale evidence for an association between chronic rhinosinusitis and the risk for cancer, suggesting a possible role for cancer surveillance in patients with the inflammatory condition, researchers said.

Results from Asia suggest chronic rhinosinusitis is associated with an increased risk for cancer, but whether these results apply to the US population remains uncertain.

How Multi-Cancer Early Detection Is Reshaping Oncology — Dr. Tomasz Beer, MD — Exact Sciences

With Dr. Tomasz (Tom) Beer MD – Chief Medical Officer for MCED at Exact Sciences

From precision oncology pioneer to leading the shift toward population-scale early detection via blood-based tech. The future of cancer care: intercepting it before it’s too late.

Dr. Tomasz Beer, MD is a nationally recognized medical oncologist and clinical research leader who serves as Chief Medical Officer for Multi-Cancer Early Detection at ‪@ExactSciences‬ Corporation (https://www.exactsciences.com/), a molecular diagnostics company focused on the eradication of cancer by preventing it, detecting it earlier, and guiding personalized treatment.

Before joining Exact Sciences, Dr. Beer spent decades at the forefront of academic oncology, including serving as Deputy Director of the Oregon Health & Science University (OHSU) Knight Cancer Institute, where he helped build one of the country’s leading precision cancer programs.

A prostate cancer specialist by training, Dr. Beer has led numerous clinical trials, authored hundreds of peer-reviewed publications, and been a driving force in advancing biomarker-guided cancer therapy. His career has spanned the evolution of oncology—from empiric chemotherapy to precision medicine and now toward population-scale cancer detection.
