As mentioned in the post (https://lemmygrad.ml/post/5205977) discussing a rule about anti-promotion of drugs and other substances:

If a lot of people oppose this rule, either by downvotes and/or number of comments, I will willingly step down as moderator of this community.

I didn't see a large opposition to this rule which has now been deleted (see https://lemmygrad.ml/post/5220158), but I will pass the moderator position back to the instance admins nevertheless, specifically to @GrainEater@lemmygrad.ml who gave me the position when I requested it months ago. This post can be used to select new moderators by leaving a comment if you're interested. I will also take part in applying to become a mod.

I'm sure some have seen the discussion around a new rule against the promotion of various substances in this community. This will be the summary based on data collected at this snapshot in time.

Post score (upvotes/downvotes): 33/19 (Note that hexbear users cannot downvote)

Number of users who left comments (including me): 21

Number of comments: 51 = 19 (left by me) + 32 (others)

The following is a crude categorization of the 32 comments left by others, each category begins with the name and a 4-tuple of (number of unique users, number of comments, total comment upvotes, maximum upvotes obtained by a single comment). If the same user left multiple comments that are categorized the same, only the comment with the highest upvote will be counted when tallying upvotes, the rest are excluded.

  • Agree (2 users, 4 comments, 7 upvotes total, 4 upvotes max): Comments that agree without giving an explanation, 2 comments excluded from upvotes total.
  • Agree because history (2 users, 2 comments, 16 upvotes total, 11 upvotes max) : Comments that agree and mention China's history.
  • Agree because history but questionable (2 users, 2 comments, 20 upvotes total, 14 upvotes max) : Comments that agree because of China's history, but raised questions
  • Disagree (2 users, 2 comments, 16 upvotes total, 9 upvotes max)
  • Medical (4 users, 7 comments, 29 upvotes total, 8 upvotes max) : Comments that mention medical properties of certain substances, or their normal use in certain cultures.
  • Abstain (1 user, 1 comment, 7 upvotes total, 7 upvotes max)
  • Others: Discuss rule (4 users, 7 comments), Joke (5 users, 5 comments), Off-topic (1 user, 2 comments)

The data show that most people agree to the rule partially due to China's history, but also question the necessity of having this rule and it's phrasing. Some people raised valid points about the medical properties of certain substances, and discussed changes to the rule to accommodate those points. Disagreements were seen mostly in downvotes or questions about the rule, only a few users left comments explicitly opposing the rule.

Overall I would conclude that there isn't a strong consensus to keep this new rule, especially not in its original phrasing, and modifications to the rule have not been thoroughly discussed. There has also not been any evidence to an urgent need for the rule. Thus the rule will be deleted from the community rules in the spirit of democratic centralism.

Visiting the National Library of China in Beijing — the largest library in Asia and one of the largest libraries in the world — to understand why so many people come here to study.

Through a night visit and a real-time tour, I look beyond the architecture to focus on the people inside: what they are studying, how long they study for, and why libraries in China play such an important role in everyday life.

Chinese engineers build nuclear reactors far faster, and at far lower costs than the United States, France, and Japan.

The Chinese nuclear industry is building half of the plants now under construction, and exports new reactors to their closest trading partners.

The countries in the BRICS+ bloc, and in the countries involved in China's Belt and Road Initiative, are resource-rich in uranium, and in key mining and enrichment industries for nuclear fuel.

The BRI countries now enjoy an end-to-end value chain of uranium, nuclear power plants, and energy transmission completely outside Western systems.

Chinese scientists have developed a plant-inspired method to convert carbon dioxide and water into valuable chemicals, such as the building blocks for petrol, by using solar energy.

The process – inspired by photosynthesis, where plants harness sunlight, carbon dioxide and water to generate energy – could help produce a sustainable source of fuel, the researchers said.

The team, from the Chinese Academy of Sciences and the Hong Kong University of Science and Technology, said they had developed a material able to store small amounts of electrical energy to help efficiently drive chemical reactions.

When paired with catalysts that converted carbon dioxide into various chemicals, it enabled the solar-driven production of carbon monoxide.

This could be further converted into fuel, offering a possible alternative for hard-to-electrify sectors such as aviation and shipping.

“This work establishes a bioinspired charge reservoir strategy for efficient carbon dioxide photoreduction, providing a universal approach to solar fuel production,” the team wrote in a paper published in the peer-reviewed journal Nature Communications last week.

Chinese researchers have revealed progress on a weapon concept that could compress hypersonic performance into a form small enough for conventional artillery.

The team is developing an ultra-small, smart hypersonic glide missile that can be fired from an 80mm anti-aircraft gun

If deployed, the system could blur the line between traditional gunfire and missile-based air defense.

According to the research, the projectile exits the gun barrel at speeds approaching Mach 6. That velocity far exceeds conventional anti-aircraft shells.

It also gives the weapon extended reach. Simulations suggest it can engage fighter jets or drones more than 20 km, or 12 miles, away.

Targets flying at altitudes around 10,000 meters, or 32,800 feet, would also fall within range.

The concept relies on speed, scale, and cost. The projectile’s small size and hypersonic flight profile sharply reduce warning time for enemy aircraft.

That compression of reaction windows could alter air combat dynamics.

As reported by the South China Morning Post (SCMP), the missile’s designers argue that detection would come dangerously late for defending aircraft.

At such extreme speed, onboard warning systems may only spot the projectile when it is about 2 miles away.

That distance leaves only seconds to respond.

Even at that point, the missile would still travel at roughly Mach 3.6. Computer simulations show it can adapt aggressively.

If a target executes a near-90-degree turn, the missile can still correct its trajectory.

The models indicate a kill probability of 99 percent.

Rate of fire adds to the threat. A standard anti-aircraft gun can fire roughly once per second.

That enables repeated launches without relying on expensive interceptor missiles.

Researchers suggest the low cost and high availability of such projectiles could challenge medium- and short-range air defense systems.

Two-stage guidance system

Extreme speed also introduces control challenges. Hypersonic projectiles face intense aerodynamic forces during sharp maneuvers.

Traditional guidance methods may fail under such conditions, increasing the risk of misses.

To overcome this, Wang Xugang’s team designed a two-stage guidance architecture.

The first stage manages the mid-course flight. It plans an efficient trajectory that preserves speed and energy.

The second stage governs the terminal phase. It focuses on fine adjustments during the final seconds before impact.

The researchers used a mathematical approach called “multi-objective optimisation” to balance speed retention with smooth maneuvering.

This approach reduces stress on the projectile while maintaining accuracy.

In the terminal phase, the missile switches to an advanced “sliding-mode variable-structure guidance” law.

This method allows the projectile to anticipate target movement and closely track even highly agile aircraft.

Simulations show the guidance method reduces maneuver load by more than 90 percent compared with conventional approaches.

Shifting air combat models

The researchers argue the technology could reshape future air warfare. “Hypersonic guided projectiles represent a new generation of precision-strike weapons,” the team wrote.

“With advantages such as rapid strike, precision guidance and high lethality, they are profoundly reshaping traditional firepower combat models and have broad application prospects in future air warfare.”

The findings appear in a peer-reviewed paper published last month in the Journal of Naval Aviation University.

While the system remains at the simulation stage, the work highlights China’s growing interest in compact hypersonic weapons designed for scalable deployment.

If proven viable, such systems could complicate air operations and force changes in aircraft defense strategies.
