DARPA Plans to Build Structures Directly in Space

Instead of launching massive structures from Earth, DARPA’s NOM4D program aims to build them directly in orbit using advanced manufacturing. This could revolutionize space construction by eliminating launch constraints like weight and size.

- What will they build?
Large antennas, solar arrays, and reflectors—assembled or even printed in space.

This tech could lead to orbital factories and lunar bases, using materials from the Moon or asteroids. If successful, it’s a major step toward a true space economy.

Crowd Movement Follows a Vortex Pattern, Physicists Find

Crowds don’t move chaotically—physicists from École Normale Supérieure de Lyon (France) have shown that large groups of people form rotating vortices instead.

The researchers analyzed crowd dynamics during the San Fermín festival in Spain, using balcony-mounted cameras and computational models. Unlike previous studies that treated crowds as clusters of individual agents, they modeled the crowd as a dense, fluid-like continuum.

As the crowd filled the square, it reached a critical density of 4 people per square meter, triggering the slow formation of overlapping vortices. When density rose to 9 people per square meter, new vortices appeared every 18 seconds. Interestingly, participants were likely unaware they were moving in circles.

Scientists Capture Rare Footage of “Black Ejections” on the Sun

Researchers have shared remarkable footage of rare “black ejections” on the Sun, captured by the Solar Astronomy Laboratory of the Space Research Institute (IKI) and the Institute of Solar-Terrestrial Physics (ISZF) of the Russian Academy of Sciences.

The video reveals a “ghostly structure of an intense black color,” part of which is ejected into space while the rest dissipates in the solar corona.

This black plasma cloud is associated with a cold prominence containing large amounts of neutral hydrogen. This hydrogen can almost completely absorb the short-wavelength radiation falling on it from behind. The entire process lasted about three hours.

Stay tuned for more fascinating discoveries!

The image doesn’t show a mission control center for space exploration; instead, it’s the control room of the EAST experimental fusion reactor. Located at the Institute of Plasma Physics under the Chinese Academy of Sciences, EAST has set a new record for plasma confinement—1,066 seconds. The previous record of 403 seconds was also achieved there in 2023. This is a major breakthrough.

The key takeaway is that physicists have developed a way to sustain plasma for over 1,000 seconds. ITER, the world’s largest fusion reactor under construction in France, is expected to operate using similarly long pulses. Chinese experts are actively contributing to the ITER project, making this achievement a win for the global scientific community.

Unfortunately, as is often the case with updates from Chinese research centers, the information provided is incomplete. For example, there is no mention of the plasma’s temperature. In previous EAST experiments, it reached 120 million degrees Celsius, whereas ITER’s plasma is expected to exceed 150 million degrees (and up to 300 million degrees at its core).

Nevertheless, this is excellent news. Now we wait to see how Japan responds. Over a year ago, experiments began at JT-60SA, currently the largest tokamak in operation. It is designed to confine plasma at temperatures of up to 200 million degrees.

This is no joke: the future power of the United States will be built on the capabilities of artificial intelligence. Deals will not be offered to states, but directly to individuals—control in exchange for health, education, and more. For example, microchipping in return for a long life with a guaranteed standard of living.

Larry Ellison of Oracle predicts that AI will develop mRNA vaccines tailored to each individual, producing them robotically within 48 hours.

Incredible Results of AI in Education: Transforming Learning Outcomes

In a groundbreaking experiment, Nigerian schoolchildren used Microsoft Co-pilot Tutor for six weeks (two sessions per week). The results were staggering: their academic progress was equivalent to two additional years of schooling. This approach proved to be 80% more effective than any other pedagogical intervention to date.

Why AI is a Game-Changer in Education:
• Unmatched Impact: The educational benefits of AI are among the most significant across any field today.
• Ready-to-Deploy Technology: Unlike other sectors where reliability or safety concerns exist, AI in education is robust and scalable (up to at least the PhD level).
• Efficiency: Accelerated learning at a fraction of the time and cost.

The Opportunity:

This success story highlights the immense potential for AI-powered educational solutions. With the technology already mature, it’s only a matter of time before someone (for now, Microsoft) builds a multi-billion-dollar business in this space.

Education is being revolutionized—and it’s only the beginning.

DIY Fusion: How to Build a Nuclear Reactor in Your Kitchen (with AI)

A guy managed to assemble a neutron fusion reactor in his kitchen, using AI as his consultant. 🔬

Technical Specs:
• 30kV/10mA Electrostatic Precipitator
• Vacuum at 3 mTorr (253,333 times deeper than atmospheric pressure!)
• Bubble Detector for neutron counting
• Homemade Deuterium extracted from heavy water via electrolysis

The most impressive part? The entire deuterium production process cost just $112:
• $32 for a hydrocar PEM
• $80 for 50g of D₂O (heavy water)

From this, he managed to produce 56 liters of D₂ gas! 🧪

How AI Helped:

The author heavily relied on Claude for:
• Process debugging
• Safety checks
• Following complex instructions

While this isn’t a commercial reactor, as a demonstration of AI-assisted DIY, it’s absolutely mind-blowing. 🔥

The Journey:

The build was live-streamed over 36 hours straight. Remarkably, just months earlier, the same individual assembled a plasma reactor. What’s even more fascinating? He didn’t have deep expertise in nuclear physics—he simply asked Claude the right questions. Independent study would have required thousands (if not tens of thousands) of hours.

The Bigger Picture:

As exciting as this is, it’s also a bit terrifying. If a hobbyist can pull this off in fusion, imagine the possibilities with biology. We might someday look back at bats with nostalgia. 🦇

AI-powered DIY is here, and it’s opening doors to both innovation and ethical challenges.

Which Side of the Singularity Are We On?

The surge of optimism surrounding our approach to AGI might not be unwarranted. On January 4, Sam Altman (regardless of your opinion of him, he is currently the most influential figure in AI) described his current status as: “near the singularity; unclear on which side.” Two days later, in an interview, he clarified that AGI would be created during Trump’s presidency—by 2029. On the same day, he elaborated in his “Reflections”:

“We are now confident that we know how to build AGI in the traditional sense. We believe that by 2025, we could see the first AI agents integrated into the workforce, fundamentally transforming company outcomes. […] We are beginning to target […] true superintelligence.”

If Altman’s prediction proves accurate, the implications for humanity will be monumental. In comparison, any events we currently consider critical—such as tomorrow’s inauguration of Trump—will pale into insignificance against the backdrop of the world being drawn into the black hole of the singularity.

So, what happened that brought us so close to the singularity, with AGI predictions suddenly accelerating? What caused timelines to plummet so drastically (as seen in the Exponential View chart referenced)?

Only Sam himself knows for sure. However, a compelling and straightforward explanation was offered by Gwern Branwen in a comment on Ryan Kidd’s post about the new paradigm of scaling outputs:

“I think what’s missing in the discussion of the scaling paradigm is the self-play feedback loop: much of the value of a model like o1 isn’t in its deployment, but in generating training data for the next model. Every problem solved by o1 now serves as a training data point for o3 (e.g., any o1 session that eventually stumbles upon the correct answer can be refined to eliminate dead ends and produce a clean walkthrough to train more nuanced intuition).”

You can test this hypothesis yourself with a simple four-step experiment:
1. Take a transcript of your conversation with ChatGPT on a problem it failed to solve satisfactorily.
2. Submit this transcript to Claude, asking it to solve the problem.
3. Review Claude’s response, which, even if not a perfect solution, will likely be significantly better than ChatGPT’s initial attempt.
4. Now reverse the roles: for another problem, give Claude’s unsatisfactory response to ChatGPT. Most likely, the same pattern will repeat—the second model will outperform the first by leveraging its output as training data.

This aligns with the historical development of AlphaGo versions: AlphaGo Fan, AlphaGo Lee, AlphaGo Master, and AlphaGo Zero. The last version trained entirely on self-play without human data. In just two years, the Elo rating of new versions skyrocketed from 3300 (already above most world champions) to an unimaginable 5185. After 2018, DeepMind ceased developing AlphaGo or participating in official matches, as it had become both uninteresting and meaningless—humans couldn’t come close to competing.

If Gwern Branwen is correct, this reflects the powerful effect of a “data flywheel,” where each new model generates data to train an even better one.

And if that’s the case, then Sam Altman is also right. Tomorrow’s inauguration of Trump, an event considered globally significant today, will fade into a trivial footnote as Earth enters the era of the singularity.

Fresh Evidence of Quark-Gluon Plasma Droplets

Quark-gluon plasma, the primordial state of matter that filled the universe just moments after the Big Bang, has been directly observed in a groundbreaking discovery. Previously, physicists believed that colliding large ions with smaller ones couldn’t produce this exotic state of matter, the building blocks of protons and neutrons.

However, new data from the PHENIX experiment challenges this assumption. The findings provide the first direct evidence that high-energy particles created in a collider can lose energy and momentum, forming tiny droplets of quark-gluon plasma.

Dive deeper into this fascinating discovery here: Phys.org.

Unitree G1 Gets Even More Agile and Dynamic

The Unitree G1 has received an update, making it even more agile and adaptable. It has now mastered running on rough terrain, showcasing its enhanced mobility and balance.

Interestingly, I think I might have figured out why its movements sometimes appear a bit unnatural. My guess is that there’s a gyroscope located in its center of mass, but that’s just a theory for now.

By the way, the Chinese New Year falls on January 29 this year. I have a feeling they’ll roll out even more updates in time for the celebrations. Let’s wait and see!

Language shapes thought, and not just for humans.

Why does o1 sometimes think in Chinese?

After the release of o1, some users noticed an intriguing phenomenon: during reasoning, the model occasionally switches to… Chinese (example). The final answer is always provided in the user’s language, but the reasoning process remains a mystery.

Interestingly, o1 isn’t the only reasoning model with this quirk. QwQ also switches to Chinese mid-reasoning. However, QwQ’s behavior is more understandable—it originates from China, and its training data is predominantly in Chinese. But why would o1, developed by OpenAI, do the same?

OpenAI has not commented on this behavior, but experts and researchers have theories. For example, the CEO of Hugging Face suggests (and it’s the most straightforward explanation) that the model was trained on a massive amount of Chinese data. Many companies, possibly including OpenAI, use Chinese annotation services, which could explain this bias.

But this raises another question: why only Chinese? The training data surely included vast amounts of text in Hindi, Thai, or Spanish. Yet, the model never switches to these languages. Why?

Some speculate this might be an intentional OpenAI experiment. Chinese tokens carry more information per token compared to other languages, making reasoning in Chinese potentially shorter and cheaper. If we consider that the model performs a kind of solution space search, reasoning in certain languages may yield correct answers more efficiently (possibly due to data imbalance), leading the model to favor these “branches.”

For now, this behavior remains a mystery. Hopefully, OpenAI will eventually shed some light on it.

China is Designing a Flag That Can Wave on the Moon

In an innovative project, scientists in China are developing a flag that will appear to wave in the vacuum of the Moon. Surprisingly, the idea for this groundbreaking technology came from elementary school students.

Unlike Earth, the Moon lacks an atmosphere, making it impossible for fabric to flutter naturally in the wind. Inspired by students’ suggestions, researchers at the Deep Space Exploration Laboratory (DSEL) are working on a solution: integrating a closed circuit into the surface of the flag. This circuit would generate bidirectional electric currents, creating electromagnetic interactions that cause the fabric to move, simulating the effect of waving.

The waving flag is set to be a symbolic and inspiring addition to the upcoming Chang’e-7 lunar mission, scheduled for 2026. While the mission’s primary goal is to search for water or ice at the Moon’s south pole, the inclusion of the innovative flag underscores the creative collaboration between scientists and the next generation of problem-solvers.

Stay tuned for more updates on cutting-edge space exploration and technological ingenuity!
