Last month, DARPA published a call for proposals on how to “grow” massive biological structures in space. It’s not as crazy as it sounds: The space race is heating up outside of the weird space biology sector. Some startups are building self-assembling space habitats, others are working on spaceports, and the ISS’s successor is in development. Let’s take a look.

At hypersonic speeds, complexities occur when the gases interact with the surface of the vehicle, such as boundary layers and shock waves. Researchers in the Department of Aerospace Engineering at The Grainger College of Engineering, University of Illinois Urbana-Champaign, were able to observe new disturbances in simulations conducted for the first time in 3D.

The study, “Loss of axial symmetry in hypersonic flows over conical shapes,” is published in Physical Review Fluids.

Fully 3D simulations require a great deal of processing power, making the work expensive to compute. Two things made it possible for Deborah Levin and her Ph.D. student Irmak Taylan Karpuzcu to conduct the research: Time on Frontera, the leadership-class computer system at the Texas Advanced Computing Center and software developed in previous years by several of Levin’s former graduate students.

Artificial Intelligence is evolving rapidly, bringing us closer to the Singularity—a future where AI surpasses human intelligence. This shift could transform every aspect of life, from jobs to technology, creating both exciting possibilities and significant risks. As AI continues to advance at an unprecedented pace, understanding its impact on society is more crucial than ever.

Key Topics Covered:
The rapid evolution of AI and its connection to the looming Singularity, where machines may surpass human intelligence.
How AI could reshape industries, jobs, and even human life as we know it.
The potential risks of uncontrolled AI growth, including the rise of misinformation, biased outcomes, and the threat of AI-designed chemical weapons.
The need for a global governance framework to regulate and monitor AI advancements.
The ethical and philosophical questions surrounding AI’s role in society, including its impact on human consciousness and labor.

What You’ll Learn:
The rapid advancement of artificial intelligence and its potential to reach the Singularity sooner than expected.
How AI systems like neural networks and symbolic systems impact modern technology and the dangers they pose when left unchecked.
The role AI could play in jobs, governance, and the potential for global cooperation to ensure safe AI development.
Insight into real-world concerns such as disinformation, biased AI systems, and even the possibility of AI leading to catastrophic societal changes.

Why This Matters:
These developments highlight the critical need for responsible AI governance as the technology progresses toward potentially surpassing human intelligence. Understanding the rapid growth of AI and its implications helps us prepare for the future, where machines could fundamentally change society. Whether you’re interested in technology, philosophy, or the future of work, this content offers an in-depth look at the powerful impact AI will have on the world.

Japan’s fledgling space defense sector is taking its cues from the US Space Development Agency, which is pursuing a novel concept based on constellations of small satellites and maximum use of existing commercial technologies. Space policy researcher Umeda Kota discusses the challenges facing Japan as it embraces the SDA’s “proliferated architecture” for military communications, missile detection and tracking, and other purposes.

The move alters the German constitution, allowing the country to increase its military spending.

Poland wants co-operation with France on a nuclear deterrent. That could take many forms.

Convergent engagement of neural and computational sciences and technologies are reciprocally enabling rapid developments in current and near-future military and intelligence operations. In this podcast, Prof. James Giordano of Georgetown University will provide an overview of how these scientific and technological fields can be — and are being — leveraged for non-kinetic and kinetic what has become known as cognitive warfare; and will describe key issues in this rapidly evolving operational domain.

James Giordano PhD, is the Pellegrino Center Professor in the Departments of Neurology and Biochemistry; Chief of the Neuroethics Studies Program; Co-director of the Project in Brain Sciences and Global Health Law and Policy; and Chair of the Subprogram in Military Medical Ethics at Georgetown University Medical Center, Washington DC. Professor Giordano is Senior Bioethicist of the Defense Medical Ethics Center, and Adjunct Professor of Psychiatry at the Uniformed Services University of Health Sciences; Distinguished Stockdale Fellow in Science, Technology, and Ethics at the United States Naval Academy; Senior Science Advisory Fellow of the SMA Branch, Joint Staff, Pentagon; Non-resident Fellow of the Simon Center for the Military Ethic at the US Military Academy, West Point; Distinguished Visiting Professor of Biomedical Sciences, Health Promotions, and Ethics at the Coburg University of Applied Sciences, Coburg, GER; Chair Emeritus of the Neuroethics Project of the IEEE Brain Initiative; and serves as Director of the Institute for Biodefense Research, a federally funded Washington DC think tank dedicated to addressing emerging issues at the intersection of science, technology and national defense. He previously served as Donovan Group Senior Fellow, US Special Operations Command; member of the Neuroethics, Legal, and Social Issues Advisory Panel of the Defense Advanced Research Projects Agency (DARPA); and Task Leader of the Working Group on Dual-Use of the EU-Human Brain Project. Prof. Giordano is the author of over 350 peer-reviewed publications, 9 books and 50governmental reports on science, technology, and biosecurity, and is an elected member of the European Academy of Science and Arts, a Fellow of the Royal Society of Medicine (UK), and a Fulbright Professorial Fellow. A former US Naval officer, he was winged as an aerospace physiologist, and served with the US Navy and Marine Corps.

Originally released December 2023._ In today’s episode, host Luisa Rodriguez speaks to Nita Farahany — professor of law and philosophy at Duke Law School — about applications of cutting-edge neurotechnology.

They cover:
• How close we are to actual mind reading.
• How hacking neural interfaces could cure depression.
• How companies might use neural data in the workplace — like tracking how productive you are, or using your emotional states against you in negotiations.
• How close we are to being able to unlock our phones by singing a song in our heads.
• How neurodata has been used for interrogations, and even criminal prosecutions.
• The possibility of linking brains to the point where you could experience exactly the same thing as another person.
• Military applications of this tech, including the possibility of one soldier controlling swarms of drones with their mind.
• And plenty more.

A new analysis of 105-year-old data on the effectiveness of “dazzle” camouflage on battleships in World War I by Aston University researchers Professor Tim Meese and Dr. Samantha Strong has found that while dazzle had some effect, the “horizon effect” had far more influence when it came to confusing the enemy.

The findings are published in the journal i-Perception.

During World War I, navies experimented with painting ships with dazzle camouflage —geometric shapes and stripes—in an attempt to confuse U-boat captains as to the speed and direction of travel of the ships and make them harder to attack.
