Chinese scientists have discovered a gene that affects corn and rice yields. When this gene is knocked out or disabled, corn yields increased by 10% in test field while rice increased by 8%.
Its the year 2050, Chinese scientist have discovered a gene that turns corn and rice into a tree, increasing yields by 1000%, world hunger has been completely eradicated.

Chinese vehicle brands have been increasingly successful in Australia these past couple of years, led by MG (SAIC) which finished the year as the 9th best selling brand, behind Volkswagen and ahead of Subaru. If you merge MG and LDV numbers (both SAIC brands, but LDV has a different distributor) then SAIC finished 7th in Australia in 2021, behind Mitsubishi and ahead of Nissan. GWM Haval is the other relevant player at #14. A local distributor is going to be bringing in BYD cars here, so it will be interesting to see how they go. China's brands are doing well enough that they are beginning to stir up nationalist opposition.

Alibaba's DAMO academy made a world record in quantum computing.

In the search for more precise qubits, superconducting qubits, transmons, are one that has received much attention in recent years. It was developed by the Robert J. Schoelkopf team at Yale around 2007. It can effectively suppress charge noise, and is easy to prepare, integrate and expand. Google claims that the experiment to achieve "quantum superiority" is implemented on a quantum computer based on this system. of.

But popularity doesn't mean the highest precision. In theory, there are many types of qubits with higher precision than transmon, such as fluxonium, which is also a superconducting qubit.

The quantum laboratory of DAMO academy "designed and manufactured a two-bit quantum processor based on the new superconducting quantum bit fluxonium, which achieved a single-bit control accuracy of over 99.97%, and a two-bit iSWAP gate control accuracy of up to 99.72%. The world's best level of such bits is achieved, and the performance is close to the mainstream transmon bits in the industry (currently, the two transmon bit gates have a maximum control accuracy of 99.85-99.87%, completed by MIT and IBM)."


Two sessions presented by Alibaba DAMO on American Physical Society's 2022 Annual Meeting:

We always talk about NEVs, jet engines, ship engines, gas turbines, that China may have comparable to the West. But what about the good old automobile ICE engine?

Introduced in 2012, Changan Automobile's Blue Core engine and powertrain was the core of Changan's autos for the next ten years and even today. The core is a 1.5 liter DOHC multivalve variable timing four cylinder engine with direct fuel injection. In 2021, the engine set a Guiness Book of Records running 259 hours above 5500 RPM. This is not to be confused with Yamaha's Blue Core engine introduced in 2015.

Rumor has it that this might be the next generation Ford EcoBoost engine for small cars, considering that Ford has a joint venture with Changan.

But... I've just browsed their main page. Their lineup doesn't look appealing to say the least. I wouldn't have said that if they hire competent designers like Geely and Haval does.
The export vehicles are pretty bland compared to their Chinese market vehicles. I think before we see more exciting Chinese vehicles overseas, we must first wait for the dust to settle in the Chinese market first.

Your wish may come true earlier. China is already testing a "giant rice" species that can grow up to 2.25 meter tall.

巨型稻,身形笔挺,穗长粒多,圆润饱满,平均每蔸水稻植株高达1.8米,高达2.25米。
“巨型水稻比一般常规水稻的生物量大50%以上,相比常规水稻,每亩可增产15%至20%。”平均每蔸水稻有约40个稻穗,稻穗的粒数多的可达800粒,每千粒稻谷重28克左右,预计亩产可突破1000公斤。

Bro, I wasn't expecting that to be true lmao. Now to do soybean, so I can eat rice mixed with soy sauce and tofu in my climate change bunker forever!

CS35 and CS75 are already being export to the Middle East and Southeast Asian countries. Here are Philippine reviews of them.

Makes sense. It has a good precedent.

GM's SGE (Small Gasoline Engine) is developed as a joint project by Opel, SAIC, MG, Shanghai GM and PATAC, which is a joint engineering center between GM and SAIC.

Its been powering a number of Chinese cars since 2013 and US cars since 2016, many of them well known nameplates such as the Chevy Equinox starting 2018.
