I wonder how much of the government money on R&D is usually spent on conferencing.

Also don’t forget the US ban on some scientific instruments. I read somewhere that half of Chinese spending on basic research was on importing scientific instruments.

you'd actually be surprised how far you can get with basic self developed systems that you can build or buy as an individual (!). Yhat does require quite alot of time and knowledge, which is not conducive to paper publishing unless you publish in an actual instrument journal. However, one thing I noticed was that Chinese scientists are now starting to publish instrumentation papers in mainstream journals as a 'new method', which is amazing.

It would be interesting to know how much energy went into making a kcal of starch compared to the usual means through planting crops. ​

BEIJING, Sept. 24 (Xinhua) -- Chinese scientists have developed an artificial method of synthesizing starch from carbon dioxide, the first of its kind globally.
The study, conducted by the Tianjin Institute of Industrial Biotechnology under the Chinese Academy of Sciences, was published in the journal Science on Friday.
As a major component of food, starch is generally produced by crops through photosynthesis. Starch synthesis in nature needs about 60 metabolic reactions and complex physiological regulation.
Many studies have been carried out globally on starch synthesis, but little progress had been made before.
The research team has designed an artificial starch synthesis pathway consisting of only 11 core reactions, achieving complete synthesis from carbon dioxide to starch molecules in the laboratory for the first time, said Ma Yanhe, Director General of the Tianjin Institute of Industrial Biotechnology.
The structure of the synthetic starch was proved to be the same as that of natural starch, said Ma, who is also the corresponding author of the study. Enditem

Another report on the artificial synthesis of starch from carbon dioxide. This one, from Global Times, informs in more details the possible revolutionary impact of this groundbreaking discovery.

As usual, it remains to be seen if it could become economically viable. From the Phys.org article it didnt mention the energy cost

If it could be used economically, then this achievement is a one-way card for the R&D team to get a Nobel

Btw, Mars' atmosphere is 96% carbon dioxide ;)

According to the zhihu post from one of the key member of this research, the future plan of such technology or perhaps discovery will likely to be implemented for industrialization (starch for industrial use), around 5-6 acre of corns can be replaced by one cubic meter size of bioreactor, also because they have only managed to synthesis so little of the starch that they were not even able to taste it :)

From the phys.org article:

“ The artificial route can produce starch from CO2 with an efficiency 8.5-fold higher than starch biosynthesis in maize, suggesting a big step towards going beyond nature.”

I assume it’s energy efficiency that’s being discussed.

Who needs a Nobel?
There no need to aspire for an award voted by a few hundred Norwegian neo-nobility with questionable agendas. China may set up Science awards with millions in Prize money and give it to these scientists.

As for Mars, the best way to transform that planet cost effectively would be to deploy bio engineered microbes. Mars ought to be a worst case disaster shelter for humanity and nothing more. That planet isn't at all suitable for life.

Think of how much land area devoted to planting you can save if this process could be industrialized.

Fusion cant come fast enough.

There are so many revolutionary technologies that are stored somewhere unused because they are not economical for the energy cost.

Fusion would catapult human civilisation to new heights. *insert meme, just wait for another 4 decades..*
