schwit1 shares a report from CNN: A private Chinese space firm successfully sent its Zhuque-3 rocket to orbit but failed in its historic attempt to re-land the rocket booster Wednesday -- the first such trial by a Chinese firm as the country's growing commercial space sector races to catch up with American rivals like SpaceX. The rocket entered orbit as planned, but its first stage did not successfully return to a landing site, instead crashing down, the company said in a statement.

"An anomaly occurred after the first-stage engine ignited during the landing phase, preventing a soft landing on the designated recovery pad," the statement said. "The debris landed at the edge of the recovery area, resulting in a failed recovery test." The team would "conduct a comprehensive review" and continue to "advance the verification and application of reusable rocket technology in future missions," the statement added.

China's private launch firm LandSpace is preparing the debut flight of its Zhuque-3 rocket, aiming to become the country's first to land a reusable orbital-class booster using a Falcon-9-style return profile. Ars Technica reports: Liftoff could happen around 11 pm EST tonight (04:00 UTC Wednesday), or noon local time at the Jiuquan Satellite Launch Center in northwestern China. Airspace warning notices advising pilots to steer clear of the rocket's flight path suggest LandSpace has a launch window of about two hours. When it lifts off, the Zhuque-3 (Vermillion Bird-3) rocket will become the largest commercial launch vehicle ever flown in China. What's more, LandSpace will become the first Chinese launch provider to attempt a landing of its first stage booster, using the same tried-and-true return method pioneered by SpaceX and, more recently, Blue Origin in the United States.

Construction crews recently finished a landing pad in the remote Gobi Desert, some 240 miles (390 kilometers) southeast of the launch site at Jiuquan. Unlike US spaceports, the Jiuquan launch base is located in China's interior, with rockets flying over land as they climb into space. When the Zhuque-3 booster finishes its job of sending the rocket toward orbit, it will follow an arcing trajectory toward the recovery zone, firing its engines to slow for landing about eight-and-a-half minutes after liftoff. At least, that's what is supposed to happen. LandSpace officials have not made any public statements about the odds of a successful landing -- or, for that matter, a successful launch...

Bruce66423 shares a report from the Los Angeles Times: Tattoo ink doesn't just sit inertly in the skin. New research shows it moves rapidly into the lymphatic system, where it can persist for months, kill immune cells, and even disrupt how the body responds to vaccines. Scientists in Switzerland used a mouse model to trace what happens after tattooing. Pigments drained into nearby lymph nodes within minutes and continued to accumulate for two months, triggering immune-cell death and sustained inflammation. The ink also weakened the antibody response to Pfizer Inc. and BioNTech SE's COVID vaccine when the shot was administered in tattooed skin. In contrast, the same inflammation appeared to boost responses to an inactivated flu vaccine. "This work represents the most extensive study to date regarding the effect of tattoo ink on the immune response and raises serious health concerns associated with the tattooing practice," the researchers said. "Our work underscores the need for further research to inform public health policies and regulatory frameworks regarding the safety of tattoo inks."

The findings have been published in the journal Proceedings of the National Academy of Sciences.

An anonymous reader quotes a report from the New York Times: The San Francisco city attorney filed on Tuesday the nation's first government lawsuit against food manufacturers over ultraprocessed fare (source may be paywalled; alternative source), arguing that cities and counties have been burdened with the costs of treating diseases that stem from the companies' products. David Chiu, the city attorney, sued 10 corporations that make some of the country's most popular food and drinks. Ultraprocessed products now comprise 70 percent of the American food supply and fill grocery store shelves with a kaleidoscope of colorful packages. Think Slim Jim meat sticks and Cool Ranch Doritos. But also aisles of breads, sauces and granola bars marketed as natural or healthy.

It is a rare issue on which the liberal leaders in San Francisco City Hall are fully aligned with the Trump administration, which has targeted ultraprocessed foods as part of its Make America Healthy Again mantra. Mr. Chiu's lawsuit, which was filed in San Francisco Superior Court on behalf of the State of California, seeks unspecified damages for the costs that local governments bear for treating residents whose health has been harmed by ultraprocessed food. The city accuses the companies of "unfair and deceptive acts" in how they market and sell their foods, arguing that such practices violate the state's Unfair Competition Law and public nuisance statute. The city also argues the companies knew that their food made people sick but sold it anyway.

schwit1 shares a report from Behind The Black: In its war with the Ukraine, it appears Russia is still managing to obtain black market Starlink mini-terminals for use on its drones, despite an effort since 2024 to block access. [Imagery from eastern Ukraine shows a Russian Molniya-type drone outfitted with a mini-Starlink terminal, reinforcing reports that Russia is improvising satellite-linked UAVs to extend their communication and operational range.] SpaceX has made no comment on this issue.

According to the article, Ukraine is "exploring alternative European satellite providers in response, seeking more secure and controllable communications infrastructure for military operations." While switching to another satellite provider might allow Ukraine to shut Starlink down and prevent the Russians from using it within its territory, doing so would likely do more harm to Ukraine's military effort than Russia's. There isn't really any other service comparable at this time. And when Amazon's Leo system comes on line it will face the same black market issues. I doubt it will have any more success than SpaceX in preventing Russia from obtaining its terminals.

Overall this issue is probably not a serious one militarily, however. Russia is not likely capable of obtaining enough black market terminals to make any significant difference on the battlefield. This story however highlights a positive aspect of these new constellations. Just as Russia can't be prevented from obtaining black market terminals, neither can the oppressed citizens in totalitarian nations like Russia and China be blocked as well. These constellations as designed act to defeat the censorship and information control of such nations, a very good thing.

A Soyuz launch at Baikonur damaged Russia's only launchpad capable of sending astronauts and crucial propellant to the ISS. "The rocket itself headed to space without incident, taking three astronauts -- Sergey Kud-Sverchkov and Sergei Mikaev of Russia and Chris Williams of NASA -- to the space station," reports the New York Times. "But the force of the rocket's exhaust shoved a service platform used for prelaunch preparations out of its protective shelter. The platform fell into the flame trench below." From the report: Photos and videos of the launch site the next day showed the platform out of place and mangled. "It's heavily damaged," said Anatoly Zak, who publishes RussianSpaceWeb.com, a close tracker of Russia's space activities, "and so probably it will have to be rebuilt. Maybe some of the hardware can be reused. But it fell down, and it's destroyed."

This is the latest embarrassment for the once-proud Russian space program, which the United States relied on from 2011 to 2020 to get NASA astronauts to orbit. The incident also raises questions about the future of the International Space Station if the launchpad cannot be quickly repaired. In a statement issued on Friday, Roscosmos, the state corporation in charge of the Russian space program, confirmed unspecified "damage" at the launchpad. "All necessary parts needed for repairs are at our disposal, and the damage will be dealt with in the near future," it said.

After a successful November 27th launch to the International Space Station, Russia discovered an accident had occurred on their launch site's mobile maintenance cabin — when a drone spotted it lying upside down in a flame trench. "The main issue with the structure collapse is that it puts Site 31/6 — the only Russian launch site capable of launching crew and cargo to the International Space Station (ISS) — out of service until the structure is fixed," reports the space-news site NASA Spaceflight There are other Soyuz 2 rocket launch pads, but they are either located at an unsuitable latitude, like Plesetsk, or not certified for crewed flights, like Vostochny, or decommissioned and transferred to a museum, like Gagarin's Start at Baikonur. As a result, Russia is temporarily unable to launch Soyuz crewed spacecraft and Progress cargo ships to the ISS, whose nearest launch (Progress MS-33) was scheduled for December 21....

When the rocket launched, a pressure difference was created between the space under the rocket, where gases from running engines are discharged, and the nook where the [144-ton] maintenance cabin was located. The resulting pressure difference pulled the service cabin out of the nook and threw it into the flame trench, where it fell upside down from a height of 20 m. Photos of the accident showed significant damage to the maintenance cabin, which, according to experts, is too extensive to allow for repairs. The only way to resume launches from Site 31/6 is to install a spare maintenance cabin or construct a new one.

Despite the fact that the fallen structure was manufactured in the 1960s, two similar service cabins were manufactured recently at the Tyazhmash heavy-engineering plant in Syzran for other Soyuz launch complexes at the Guiana Space Center and Vostochny Cosmodrome. The production of each cabin took around two years to complete, however, it was not for an emergency situation.
"Various experts gave different possible estimates of the recovery time of the Site 31 launch complex: from several months to three years."

An anonymous reader shared this report from The Conversation: To make interplanetary travel faster, safer, and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs. We're a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind's journey to the stars...

Early nuclear thermal propulsion designs from the 1960s, such as those in NASA's NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations — from beds of ceramic pebbles to grooved rings with intricate channels... [T]he more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates. This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables — from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer.

Psychology Today reports: In a study conducted in Milan, Italy, and published in November 2025, the sight of a person dressed as Batman led to a nearly doubled rate of people giving up their seat to a pregnant woman. Over the course of 138 subway rides, researchers found that people who saw "Batman" standing near the pregnant woman were far more altruistic than those who did not.

Researchers are calling this the "Batman effect," suggesting a form of "involuntary" mindfulness may be at play. Noticing these subtle social cues appears to shift people's typical, automatic reactions. Most interestingly, 44 percent of the people questioned reported they did not even consciously register Batman's presence... The superhero costume serves as a visual nudge, pulling us out of our default, self-focused mode and into a more generous, attentive state.
More from Futurism: Batman showing up is just one — albeit striking — way of promoting what's called "prosocial behavior," or the act of helping others around you, via introducing an unexpected event, the researchers write. "Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality," said study lead author Francesco Pagnini, a professor of clinical psychology at the Università Cattolica in Milan, in a statement about the work. "This may create a context in which individuals become more attuned to social cues."

A new study published in Communications Earth & Environment has reconstructed the climate conditions of the ancient Indus River Valley civilization between 3000 and 1000 B.C., finding that four intense droughts -- each lasting more than 85 years -- likely drove the gradual decline of one of the world's earliest advanced societies.

The research team, led by Hiren Solanki at the Indian Institute of Technology, Gandhinagar, combined paleoclimate data from cave formations and lake records with computer models to determine that the region shifted from wetter-than-present monsoon conditions to prolonged dry spells as the tropical Pacific Ocean warmed. The third drought, peaking around 1733 B.C., proved the most severe: it lasted 164 years, reduced annual rainfall by 13%, and affected nearly the entire region.

Overall temperatures rose by 0.5 degrees Celsius and rainfall dropped between 10 and 20%. These changes shrank lakes and rivers, dried soils, and made agriculture increasingly difficult in areas away from major waterways. Harappan settlements progressively relocated eastward toward the Indus River over roughly 2,000 years. The civilization's long survival under repeated climate stress -- through crop switching, trade diversification, and settlement relocation -- offers lessons for modern communities facing environmental pressures, the researchers said.

Twenty years after surgeons in France performed the world's first face transplant, the experimental field that procedure launched is now confronting a troubling record of patient deaths, buried negative data and a healthcare system that leaves recipients financially devastated and medically vulnerable.

About 50 face transplants have been performed globally since Isabelle Dinoire received her partial face graft at University Hospital CHU Amiens-Picardie in November 2005. A 2024 JAMA Surgery study reported five-year graft survival of 85% and 10-year survival of 74%, concluding that the procedure is "an effective reconstructive option for patients with severe facial defects." The study did not track psychological wellbeing, financial outcomes, employment status or quality of life. Roughly 20% of face transplant patients have died from rejection, kidney failure, or heart failure.

The anti-rejection medications that keep transplanted faces alive can destroy kidneys and weaken immune systems to the point where routine infections become life-threatening. In the United States, the Department of Defense has funded most operations, treating them as a frontier for wounded veterans, because private insurers refuse to cover the costs. Patients who survive the surgery often find themselves unable to afford medications, transportation to follow-up appointments or basic caregiving. The field's long-term grants cover surgical innovation but not the lifelong needs of the people who receive these transplants.

An anonymous reader shares a report: NASA has slashed the number of astronaut missions on Boeing's Starliner contract and said the spacecraft's next mission to the International Space Station will fly without a crew, reducing the scope of a program hobbled by engineering woes and outpaced by SpaceX. The most recent mishap occurred during Starliner's first crewed test flight in 2024, carrying NASA astronauts Butch Wilmore and Suni Williams. Several thrusters on Starliner's propulsion system shut down during its approach to the ISS.

China's new JUNO neutrino observatory has delivered world-leading measurements after just 59 days, offering the most precise readings yet of two key neutrino oscillation parameters. "The physics result is already world-leading in the areas that it touches," says particle physicist Juan Pedro Ochoa-Ricoux of the University of California, Irvine, who co-leads a team on JUNO. "In particular, we measured two neutrino oscillation parameters, and that measurement is already for both parameters the best in the world." The results were published in two separate preprints on arXiv.org. Scientific American reports: JUNO's spherical detector, which is akin to a 13-story-tall fishbowl, primarily measures so-called electron antineutrinos spewing from the nearby Yangjian and Taishan nuclear plants. When the particles strike a proton inside the detector, a reaction triggers two light flashes that ping photomultiplier tubes and get converted into electrical signals. The new measurements from these neutrino-proton collisions are now considered the most precise for two oscillation parameters, which act as proxies for differences in their mass, according to Ochoa-Ricoux.

"It is the first time we've turned on a scientific instrument like JUNO that we've been working on for over a decade. It's just tremendously exciting," Ochoa-Ricoux says. "And then to see that we're able to already do world-leading measurements with it, even with such a small amount of data, that's also really exciting." Still, the physicists will need years' worth of neutrino detections to answer the mass-ordering conundrum.

China's pharmaceutical industry has quietly evolved from a hub for generics and clinical trials into something more ambitious -- a genuine competitor in drug discovery that Western giants are now courting to fill gaps left by looming patent expirations worth over $300 billion by 2030. In the first half of 2025, nearly a third of global licensing agreements signed by big pharma involved Chinese firms, Economist reports, four times the share from 2021. Pfizer agreed in May to pay $1.25 billion to 3SBio for an experimental cancer drug, and GlaxoSmithKline followed in June with a deal valued at up to $12 billion with Hengrui. Chinese companies now run about a third of the world's clinical trials, up from 5% a decade ago.

An anonymous reader shares a report: It is shocking but not surprising. Lightning crackles on Mars, scientists reported on Wednesday. What they observed, however, were not jagged, high-voltage bolts like those on Earth, arcing thousands of feet from cloud to ground. Rather, the phenomenon was more like the shock you feel when you scuff your feet on the carpet on a cold winter morning and then touch a metal doorknob.

"This is like mini-lightning on Mars," Baptiste Chide, a scientist at the Research Institute in Astrophysics and Planetary Science in Toulouse, France, said of the centimeter-scale electrical discharges. Dr. Chide and his colleagues reported the findings in a paper published on Wednesday in the journal Nature. The electrical sparks, although not as dramatically violent as on Earth, could play an important role in chemical reactions in the Martian atmosphere.
