Additive Manufacturing in Microgravity
The most expensive part of space travel isn’t the fuel. It’s the cargo. Additive manufacturing isn’t a sci-fi magic trick; it’s the key to building shipyards and telescopes at scales rockets were never meant to handle. We aren’t just launching ships anymore; we’re moving the factory to the void.

Frozen. Thawed. Not dead: Jean Hilliard’s amazing Minnesota story
When you Google the small town of Lengby, there’s pretty much just one result that pops up, something that happened almost 40 years ago. The accounts online call it a miracle.
On the night of Dec. 20, 1980, 19-year-old Jean Hilliard’s car hit the ditch. She tried to walk for help. She was found in the morning in the front yard of a local cattle rancher — frozen solid as a log.
Barry Loewer — Fallacies of Fine-Tuning
What mistakes are made in the fine-tuning debate? Whether errors of fact, opinion, logic, or extrapolation, where are the pitfalls in fine-tuning? Is there…
Consciousness: Philosophers & Neuroscientists Defend Physicalism
In this video, leading philosophers and neuroscientists defend the view that the mind purely physical?
Starring some of the very experts who anti physicist quote such as Bob Kirk (Zombie argument) and Frank Jackson (Marys room argument) who have now turned to physicalism, as well as the most cited neuroscientists in the world, Karl Friston and other leading scholars such as Ned Block, David Papineau, Richard Brown, Ken Williford, Anil Seth and Marc Solms, we examine the strongest case for physicalism—the view that everything about the mind can ultimately be explained in terms of the physical brain.
We take on some of the most famous anti-physicalist arguments, including: The Hard Problem of Consciousness, Knowledge arguments (e.g., Mary’s Room), Philosophical zombies Dualist intuitions about the self and panpsychism.
Do these arguments really show that consciousness is non-physical—or do they rely on misconceptions about how the brain works?
This video breaks down complex ideas into clear, rigorous explanations while challenging some of the most popular objections to physicalism.
If you’re interested in philosophy of mind, consciousness, neuroscience, or the nature of reality itself, this is for you.

AI and the mysteries of reality
Does AI have the potential to uncover the mysteries of reality, or does it lack the capacity for genuine discovery?
With the 2024 Nobel Prizes for physics and chemistry both awarded for AI-related science, claims that AI will soon make novel scientific breakthroughs on its own are growing louder.
Start-ups are already attempting to create “The AI Scientist,” and researchers at Imperial College argue AI will “usher in a new age of discovery to rival the golden age of the scientific method.” But critics argue the scientific capability of AI remains unknown.
Join computer scientist Roman Yampolskiy, philosopher Steve Fuller, and co-curator of “AI: More than Human” Suzanne Livingston to debate what AI can and can’t do for science.
Tap here to watch now.
The 2024 Nobel Prizes for physics and chemistry were both won for AI-related science, leading some to claim that AI will soon be making novel scientific discoveries on its own. Start-ups are already attempting to create “The AI Scientist,” which will one day “fully automate scientific discovery.” And researchers at Imperial College argue AI will.
Liver cancer roadmap links tumor hallmarks to treatment, including targetable mutations
A new review from the Icahn School of Medicine at Mount Sinai and the Hospital Clínic de Barcelona provides one of the clearest roadmaps to date for understanding and treating liver cancer, one of the deadliest cancers worldwide. Published in Cell, the study, “Hallmarks of Liver Cancer: Therapeutic Implications”, applies the widely used “Hallmarks of Cancer” framework to liver tumors, linking the biology of the disease to treatment strategies, including immunotherapy and precision medicine approaches, particularly in the approximately 45% of bile duct cancers that harbor targetable mutations.
The study was led by Josep M. Llovet, MD, Ph.D., Professor of Medicine at the Icahn School of Medicine (Liver Diseases) at Mount Sinai and Director of the Liver Cancer Program at the Mount Sinai Tisch Cancer Center; and Daniela Sia, Ph.D., Associate Professor of Medicine (Liver Diseases) at the Icahn School of Medicine.
Marking the 25th anniversary of the groundbreaking “Hallmarks of Cancer” framework introduced by Douglas Hanahan, Ph.D. (Swiss Institute for Experimental Cancer Research), and Robert A. Weinberg, Ph.D. (Massachusetts Institute of Technology), the Mount Sinai-led team applies this influential model specifically to primary liver cancer, offering new insights into disease biology and treatment strategies.
Scientists Reveal Why Bread Can Cause Weight Gain Without Overeating
New research in mice shows how eating bread can cause body weight and fat mass to increase, even though caloric intake stays at a similar level.
The research, led by a team from Osaka Metropolitan University in Japan, highlights how carbohydrates can contribute to weight gain as well as excessive fat intake – which is what dietary advice tends to focus on.
This isn’t the first time nutritionists have talked about bread and carbohydrates and their contribution to weight gain, but there hasn’t been much detailed research into the relationship – especially wheat flour – or into what might be happening at a metabolic level.
