Space propulsion company Pulsar Fusion has started construction on a large nuclear fusion chamber in England, as it races to become the first firm to fire a nuclear fusion-powered propulsion system in space.

Nuclear fusion propulsion tech, arguably a golden goose of the space industry, could reduce the travel time to Mars by half and cut the travel time to Titan, Saturn’s moon, to two years instead of 10. It sounds like science fiction, but Pulsar CEO Richard Dinan told TechCrunch in a recent interview that fusion propulsion was “inevitable.”

“You’ve got to ask yourself, can humanity do fusion?” he said. “If we can’t, then all of this is irrelevant. If we can — and we can — then fusion propulsion is totally inevitable. It’s irresistible to the human evolution of space. This is happening, because the application is irresistible.”

An older research article and I really hope I didn’t already post this, but isn’t this scary? Nevermind AI or nano, but the fact you don’t need that to mess with your mind? Oh and I’ve searched google and there’s nanoparticles in meds, including psych meds. EMF could potentially mess with that or the minerals in your body but I’m not an expert. But we do have iron in our blood. I read that EMF can affect the blood brain barrier as well. I know there’s issues with people saying they’re targeted individuals, but with instructions online on how to make a microwave gun, especially on youtube, and there’s a Wired Magazine article about a court case where a judge ordered a man to stop EMF targeting a former business partner over an argument over a business deal. Yup, the 21st centure is bringing more than guns and knives and fists into the foray.

A new study from the University of Georgia aims to improve how we evaluate children’s creativity through human ratings and through artificial intelligence.

A team from the Mary Frances Early College of Education is developing an AI system that can more accurately rate open-ended responses on assessments for elementary-aged students.

“In the same way that hospital systems need good data on their patients, educational systems need really good data on their students in order to make effective choices,” said study author and associate professor of educational psychology Denis Dumas. “Creativity assessments have policy and curricular relevance, and without assessment data, we can’t fully support creativity in schools.”

All of us are at the beginning of a journey to understand generative AI’s power, reach, and capabilities. This research is the latest in our efforts to assess the impact of this new era of AI. It suggests that generative AI is poised to transform roles and boost performance across functions such as sales and marketing, customer operations, and software development. In the process, it could unlock trillions of dollars in value across sectors from banking to life sciences. The following sections share our initial findings.

Generative AI’s impact on productivity could add trillions of dollars in value to the global economy. Our latest research estimates that generative AI could add the equivalent of $2.6 trillion to $4.4 trillion annually across the 63 use cases we analyzed—by comparison, the United Kingdom’s entire GDP in 2021 was $3.1 trillion. This would increase the impact of all artificial intelligence by 15 to 40 percent. This estimate would roughly double if we include the impact of embedding generative AI into software that is currently used for other tasks beyond those use cases.

Astrophysicist Geraint Lewis of the University of Sydney in Australia recently authored a study about time dilation and said that Doctor Who’s description of time travel is accurate, as we truly don’t yet understand the limitations of time (via Reuters).

Sci-fi shows like Doctor Who can usually rely on the audience’s suspension of disbelief when diving into heady concepts, and the science doesn’t always have to be accurate — though it is much cooler when a show gets the science right. Apparently, the long-running BBC series can take pride in the fact that the Doctor’s description of time as ‘wibbly-wobbly, timey-wimey stuff, is co-opted by real-life astrophysicists.

In other words, theoretical concepts like time travel and warp drives could be possible, or they may not be. Maybe a Time Lord out there uses a British police box to travel through time. Okay, so Doctor Who probably isn’t right about that part, but there technically is still a chance that it is!

EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17-mm-thick (0.6-in) layer can block 20 Hz noise as well as a 4-m-thick (13-ft) wall.

If you know how active noise cancellation works, then skip ahead. Essentially, the sound waves we hear are pressure waves in the air around us. Speaker cones are big, lightweight membranes designed to push air around in precise patterns to create those pressure waves, either in the form of pleasant music, or whatever it is the kids are listening to these days.

Active noise cancellation (ANC) is the idea of measuring those pressure waves with a microphone, then generating the exact same pressure waves in reverse, and playing them through a speaker. Pressure is taken away from the positive pressure peaks, and added to the negative pressure troughs, and the new wave more or less scrubs the old wave out of existence.

We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long.

These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion.

And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!
