Nineteen years ago, my wife and I went to Hiroshima by high-speed ferry boat, on our way back from visiting her parents in Kyushu. Her father’s family comes from Hiroshima (although her father was actually born in Dairen/Dalian (大連), China) and her uncle and his family still live about an hour’s drive north of the city.
(Update from 2020: We visited Hiroshima with the kids for the first time last January, for New year’s 2023.)
Using the new method, one metric tonne of lunar soil will be able to produce about 51 to 76 kilograms of water, equivalent to more than a hundred 500-millileter bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said.
The soil was from the 2020 expedition, which was the first in 44 years to bring back soil from the Moon.
Considering all of NASA’s problems, it looks like China will have a moon base years before the US does…and probably in prime resource locations as well.
And don’t forget that the hydrogen in the soil can also be used for rocket fuel. It would be a lot easier to launch ships to Mars and beyond without having to deal with Earth’s gravity…
Footage making the rounds on social media shows what appear to be astonishingly lifelike humanoid robots posing at the World Robot Conference in Beijing last week.
But instead of showing off the latest and greatest in humanoid robotics, two of the “robots” turned out to be human women cosplaying as futuristic gynoids, presumably hired by animatronics company Ex-Robots.
During the World Robot Conference 2024 in Beijing from Aug 21 – Aug 25, 🇨🇳 animatronics company EX-Robot (or EX Robots as reported by some news media) hired 2 women cosplayed as robots to spice up the exhibition.
But China has also offered to share at least some of its new moon samples with American researchers, and NASA is allowing the U.S. scientists to submit proposals.
This is a welcome change of heart. International politics need not prevent international space exploration.
On the other hand…
China is not planning a mere short-term, flags-and-footprints presence on the Moon. Their ambition is more like Nasa’s Artemis than it is Apollo. China plans to launch two separate missions to the south pole of the Moon around 2026 and 2028 – including testing using lunar soil to 3D print bricks – as precursors to a lunar base.
The South Pole, where power plants are likely to be constructed (without human help…)
“The truth is that nuclear is the only option to power a moonbase,” says Simon Middleburgh from the Nuclear Futures Institute at Bangor University in Wales.
The short story accused of violating the national security law, “Our Time,” is set in a dystopian 2050. It tells of an authoritarian future in which vast swaths of Hong Kong history have been erased from both the city’s structures and the public consciousness, and all aspects of life are subsumed under the Chinese Communist Party.
I’m not sure this is science fiction. Seems more like reality.
Every political entity wants power. When people resist being controlled, and they use a dialect or another form of the “official” language, those in charge try to eliminate the language of resistance.
When people write about a dystopian future in which they have no right to their own language, customs, ways of thinking and behaving, and political representation — and those in charge respond by banning the fiction — it really only shows the reality. And the reality is this:
Those in charge have small, frail, male egos that need constant stroking. Poor frail eggshell minds.
Language is power, because language is identity. Those in charge are always afraid of losing control over all three. And whenever they respond this way, they always get exactly the opposite of what they want.
My legs, especially my left calf, still ache from Hua Shang. That experience alone justifies my whole trip. I walked 6 km starting at about 1pm. Stopping only once for maybe 15-20 minutes for a Sprite and a flashlight, I reached the North Peak (Bei Feng) at a little after 5. I really should have continued to the South Peak (the highest at 2160m), but at just before a particularly treacherous climb, a stranger offered to take my picture. He did this twice later; he then asked me where I was going, so because I told him North Peak, he led me to the North Peak Hotel. I signed into an expensive room, thinking a locked door proof against bag theft — but unnecessarily, as there were no other guests at all! I got a TV, a washbasin (no running water) and access to outdoor lavatories (Must have been the “private bath” the guidebook lied about). Public toilets basically meant an open outhouse shitting down the rock face — so much for sacred mountain vibes.
I slept and, waking at 4 am, set off to climb the Blue Dragon. Only then did I know why one traditionally climbed the mountain at night: to conquer fear. Once I began, I could not return. Grasping the iron-link chain with one hand and flashlight with the other, all I could see were tiny, steep steps underfoot and clear stars overhead. Most stairs were about 60º, but several inclined more, and at least one near the beginning of the Blue Dragon was almost vertical, certainly 80º. At the very end, just before the sunrise viewing point, was the actual peak (2100m). From atop an enormous boulder crowned with pine trees and a lone camp light came the voices of two crazy park workers, exhorting all to brave the true East Peak. A guide at the bottom told me to be careful before I attempted to climb the rock. But as I realized the steps were actually more than 90º, and that my pack was pulling me backward as I yanked myself up on the chains, I gave up and went down again after about 10 feet.
When I returned after watching daybreak, I looked down at the Dragon and could only marvel at my audacity; I had come alone at night, scared half out of my wits, with heavy packpack and asthma and glasses and only 1 free hand, and I had climbed steps narrower than the width of my foot. With sheer rock cliffs on both sides and only a single metal chain between me and a quickly plummeting death. I did it. I have nothing left to fear.
Superconductors are materials that allow electrical current to flow with no resistance, a property that would revolutionize power grids where energy is lost in transmission as well as advance fields such as computing chips, where electrical resistance acts as a speed limit.
The hallmark of science is replicability. I.e., can two independent teams of researchers, using similar means, methods, and materials in completely different settings, replicate the findings of the original team?
So…
Researchers from at least three Chinese universities have in recent days said they produced versions of LK-99 with varying results. One team from the Huazhong University of Science and Technology posted a video purporting to show the material levitating over a magnet, which is important because true superconductors can float over a magnet in any orientation, without spinning like a compass.
But…
…another team, from Qufu Normal University, said they did not observe zero resistance, one of required characteristics of a superconductor. A third, from the Southeast University in the eastern Chinese city of Nanjing, said they measured zero resistance, but only at a temperature of 110 Kelvin (-163 degree Celsius).
And…
The possible bad news for LK-99 is that the superconducting field is full of materials that hold promise at first but fall apart under scrutiny. Researchers even have a handy name for them — unidentified superconducting objects.
A.k.a “USOs.” As the linked article points out, plenty of smart, hardworking researchers have claimed to have found a “superconductor,” but then their claims simply fall apart under scrutiny.
This is the first time that has been achieved using human material. Although, they are not truly “synthetic”, as the starting material was cells cultured from a traditional embryo in the laboratory.
Great, but…
She has already developed synthetic mouse embryos with evidence of a developing brain and beating heart.
Come on, BBC. I think you can see where this is going…
Meanwhile, scientists in China have implanted synthetic monkey embryos into female monkeys – although, all the pregnancies failed.
Yep. Straight to the monkey house.
Seriously, did scientists actually think this was not going to cause a whole lot of people to get upset all over again?
Natural embryo (top), synthetic embryo (bottom). They look pretty similar…
This may indeed be a good way to study infertility causes and how embryos develop, but even the possibility of creating an embryo from a stem cell should have set off warning bells. 14-day limit or not, somebody’s going to get really tempted to do something else with them…
I’m thinking up all sorts of SciFi stories from this…
The link below includes a night sky in Montana, which makes little sense when the researchers were in Beijing and Honolulu…
“The first-generation star we observed has the potential to become the oldest star we have ever seen,” said Alexander Heger, a professor in the school of physics and astronomy at Monash University in Australia who was part of the research team. “It probably had only lived for 2 1/2 million years and then exploded.”
Oh, and it also was discovered to be 260 times the size of our own Sun…just as theorized.
More importantly, this involved scientists from three different countries (China, Japan, and Australia), sharing information and working together for science.
Imagine if that spirit of cooperation could be extended into other domains…
