Covering interstellar distances rapidly may still be a distant dream, but it’s now getting unprecedented financial support.
A nonprofit called the Limitless Space Institute, co-founded by former NASA warp drive researcher Harold “Sonny” White and retired astronaut Brian Kelly in 2020, is generating enough excitement — and funding — for the concept that it’s started giving out educational and research grants to schools and universities, as detailed by Universe Today.
The Institute, whose mission statement is to “inspire and educate the next generation to travel beyond our solar system and support the research and development of enabling technologies,” has even picked up some increasingly mainstream support. Take Gwynne Shotwell, the chief operations officer and second-in-command of SpaceX, who joined as an independent advisor in April, joining other bigshots in the aerospace sector including several retired astronauts involved with the venture.
There’s a movement afoot to counter the dystopian and apocalyptic narratives of artificial intelligence. Some people in the field are concerned that the frequent talk of AI as an existential risk to humanity is poisoning the public against the technology and are deliberately setting out more hopeful narratives. One such effort is a book that came out last fall called AI 2041: Ten Visions for Our Future.
The book is cowritten by Kai-Fu Lee, an AI expert who leads the venture capital firm Sinovation Ventures, and Chen Qiufan, a science fiction author known for his novel Waste Tide. It has an interesting format. Each chapter starts with a science fiction story depicting some aspect of AI in society in the year 2041 (such as deepfakes, self-driving cars, and AI-enhanced education), which is followed by an analysis section by Lee that talks about the technology in question and the trends today that may lead to that envisioned future. It’s not a utopian vision, but the stories generally show humanity grappling productively with the issues raised by ever-advancing AI.
IEEE Spectrum spoke to Lee about the book, focusing on the last few chapters, which take on the big issues of job displacement, the need for new economic models, and the search for meaning and happiness in an age of abundance. Lee argues that technologists need to give serious thought to such societal impacts, instead of thinking only about the technology.
One of the most tedious, daunting tasks for undergraduate assistants in university research labs involves looking hours on end through a microscope at samples of material, trying to find monolayers.
These two-dimensional materials —less than 1/100,000th the width of a human hair—are highly sought for use in electronics, photonics, and optoelectronic devices because of their unique properties.
“Research labs hire armies of undergraduates to do nothing but look for monolayers,” says Jaime Cardenas, an assistant professor of optics at the University of Rochester. “It’s very tedious, and if you get tired, you might miss some of the monolayers or you might start making misidentifications.”
“I think it is possible,” Musk, 50, recently told Insider. “Yes, we could download the things that we believe make ourselves so unique. Now, of course, if you’re not in that body anymore, that is definitely going to be a difference, but as far as preserving our memories, our personality, I think we could do that.”
By Musk’s account, such technology will be a gradual evolution from today’s forms of computer memory. “Our memories are stored in our phones and computers with pictures and video,” he said. “Computers and phones amplify our ability to communicate, enabling us to do things that would have been considered magical … We’ve already amplified our human brains massively with computers.”
The concept of prolonging human life by downloading consciousnesses into synthetic bodies has been a fixture of science-fiction for decades, with the 1964 sci-fi novel “Dune” terming such beings as “cymeks.” Some experts today believe that “mind uploading” technology could, in fact, be feasible one day — but the timeline is incredibly unclear.
Scientists are attempting to map the wiring of the nearly 100 billion neurons in the human brain. Are we close to uncovering the mysteries of the mind or are we only at the beginning of a new frontier?

Imagine navigating the globe with a map that only sketched out the continents. That’s pretty much how neuroscientists have been operating for decades. But one of the most ambitious programs in all of neuroscience, the Human Connectome Project, has just yielded a “network map” that is shedding light on the intricate connectivity in the brain. Join leading neuroscientists and psychologists as they explore how the connectome promises to revolutionize treatments for psychiatric and neurological disorders, answer profound questions regarding the electrochemical roots of memory and behavior, and clarify the link between our upbringing and brain development.

It’s said that the clock is always ticking, but there’s a chance that it isn’t. The theory of “presentism” states that the current moment is the only thing that’s real, while “eternalism” is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don’t tell us who wins the big game next year.
This video is episode two from the series “Mysteries of Modern Physics: Time”, Presented by Sean Carroll.

Chinese government-backed hackers have breached “major telecommunications companies,” among a range of targets worldwide, by exploiting known software flaws in routers and other popular network networking gear, US security agencies warned Tuesday.
“[T]hese devices are often overlooked by cyber defenders, who struggle to maintain and keep pace with routine software patching of Internet-facing services and endpoint devices,” says the advisory from the FBI, the National Security Agency and US Cybersecurity and Infrastructure Security Agency.
The agencies’ statement did not identify the victims of the hacking; the advisory was aimed at defensive measures to help organizations running the devices made by Cisco, Fortinet and other vendors, shore up their networks.
