Stanford researchers placed millions of lab-grown human neurons into mice, creating a disease model that also raises hard questions about consciousness and animal rights. NPR reported that the team used mice missing most of their cerebral cortexes, then filled much of that space with human cortical neurons grown in a laboratory.

Stanford researchers placed millions of lab-grown human neurons into mice, creating a disease model that also raises hard questions about consciousness and animal rights. NPR reported that the team used mice missing most of their cerebral cortexes, then filled much of that space with human cortical neurons grown in a laboratory. The goal was to study neurodegenerative disease and other brain conditions. But the researchers stopped when the human cells reached roughly six months of development, before possible signs of consciousness might emerge. Sergiu Pașca, a Stanford professor of psychiatry and behavioral sciences, served as the senior author. The team published its findings in the journal Nature. Pașca said scientists have spent…Open
AI-enabled bioweapons are a potentially catastrophic yet manageable risk — if government, the scientific community, the public health sector and leading tech companies can develop appropriate safeguards, a new report argues. Why it matters: The debate over AI and public safety isn't one that the health care or research communities can ignore. Driving the news: A RAND report out this week outlines nine mitigation strategies targeting a range of actors who could use AI to design and release a biological weapon. - While there's already considerable debate about government oversight and safeguards around frontier AI companies, RAND calls for more controls and a wide range of cross-industry cooperation. - It recommends protecting the same…
SUBSCRIBE for more vids~ Summary: Scientists found a lost river system beneath Antarctica, proving the continent was once vastly different. See what lies under the ice. This video explores the recent Antarctica discovery of ancient valleys and ridges that remained preserved for millions of years. We examine how this lost river system challenges previous assumptions about how ice erodes the landscape. This content is intended for anyone interested in geology, earth science, and the history of our planet. By analyzing this prehistoric landscape, researchers are gaining new insights into the stability of the current Antarctic ice sheet. Understanding these conditions helps us better model climate history and predict how polar regions may…
For generations Americans looked north and saw an immense frozen wilderness, remote from the intrigues and conflicts consuming the rest of the world. That complacent picture is now obsolete. The Arctic is becoming one of the most consequential theaters of great power competition, where shipping lanes, energy deposits, submarine routes, communications systems, military surveillance, and […] The post The Spies Beneath the Arctic Ice appeared first on StoneZone .
For generations Americans looked north and saw an immense frozen wilderness, remote from the intrigues and conflicts consuming the rest of the world. That complacent picture is now obsolete. The Arctic is becoming one of the most consequential theaters of great power competition, where shipping lanes, energy deposits, submarine routes, communications systems, military surveillance, and critical infrastructure converge beneath a deceptively tranquil landscape of ice and sea. China and Russia understand this transformation perfectly and both have been expanding their presence while Washington, D.C. has too often treated the High North as a distant geographical abstraction. On June 8, 2026 Utah Republican Senator Mike Lee introduced…Open
Researchers are using AI to create new viruses, hoping to find treatments for antibiotic-resistant infections. Is that a good thing? NewsNation's Rich Bodee explains what experts are saying.
Scientists trained artificial intelligence on libraries of DNA and then asked the model to create recipes for viral genomes. Sixteen of them were viable, yielding new viruses.
Matt Walker couldn't pet a dog without sneezing, until he and other scientists used a gene-editing technique to produce a hypoallergenic beagle named Bailey.
By Bill Ponton Henrik Svensmark’s challenge to climate dogma is as threatening to the modern-day climate church as the Copernican revolution was to the Church of the Middle Ages.
