US researchers say a robot has successfully performed keyhole surgery on pigs all on its own – without the guiding hand of a human. Furthermore, they add, the robot surgeon produced “significantly better” results than humans.
The original title of the Live Science post linked above is “China wants to build…” but this is incorrect. The National Natural Science Foundation of China is proposing a feasibility study. This is not the same thing as “China wants to build a kilometer-long ship.”
Likely the study will find out that it’s just too expensive and not worth it in terms of effort, resources, and maintenance costs. But it may show the benefits of setting up a base on the Moon and then sending materials there to be 3D-printed for future exploration or human colonies elsewhere.
Sending up a ginormous ship from Earth is foolhardy. Figuring out how to build stuff in space is much smarter.
…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.
“When they did that design, they should have stopped and thought, ‘you know, that’s going to leave a big chunk of debris in orbit, we should change the design of the engine’,” McDowell says. “But they didn’t. This is real negligence.”
Four years ago, China’s first space station landed in the Pacific Ocean between Australia and Chile, after an uncontrolled reentry. China didn’t care.
Last year, pieces from a Long March 5B rocket landed in Cote d’Ivoire. They damaged buildings in two villages. China didn’t care.
This launch of the same rocket design could land anywhere from New York to New Zealand, covering a wide range of habitation. China doesn’t care.
On the other hand, once somebody in their government reads about the criticism by the scientific community, they’ll petulantly whine that this often happened in the 1960s, so that makes it OK for them to ignore rocket safety designs known for the past 30 years.
Maybe it’s technology they haven’t yet stolen from other countries.
As the self-acknowledged center of the known universe, the Middle Kingdom only cares what others think of it. Like a spoiled child that thinks it knows everything but fears it does not, China only reacts to its own mistakes by lashing out at others and disclaiming responsibility.
If you want to be respected as a superpower, you need to learn how to respect other countries and stop dumping your trash on them. Respect is not given, it is earned. China has done little to earn any respect by the scientific community.
“This assumption is consistent with recent theoretical studies of the solar system’s evolution that suggest that asteroids rich in small, volatile molecules like water and carbon dioxide formed beyond Jupiter’s orbit before being transported to areas closer to the sun.”
However, it does show the need for STEM students and researchers in Japan to improve their English. For every study like this published in English there are many more only published in Japanese. Lots of interesting research going on in Japan that people *outside* Japan need to know about!
