News on China's scientific and technological development.

Augmented reality is a game changing technology, in my view, for productivity, especially when combined with Internet of Things. It's the next big human-focused productivity boost after mobile devices.

Virtual reality, less so at the moment, but if China takes the lead and pushes the boundaries of what it can do, it has huge commercial potential. VR has always been a promise, rather than a realization - the promise being that you can be anyone, live anywhere, have any sort of experience. But in reality, it's just 3D glasses. If China can achieve the transition to tactile sensory simulation before the West, it'll make China the center of VR applications, which will define the future of entertainment and life style.

VR will be useful in education and will be more widespread in CADCAM.

This is frankly a phenomenon I don't understand.

I don't understand it either.

Then I happened to watch this Cyrus Jensen video, (8 minutes), yes, the same Cyrus, and he explain the metaverse!

It was quite surprising! Like, mister Jensen knows everything, you know.

Given China's impressive 5G infrastructure, its not wonder they are pushing VR goggles. It will help with remote controlling machines. It will also decrease the space needed you can just use a set of VR goggles instead of having a complete array of monitors to simulate the machine's field of view. You can now just stream the camera input you get from the remote machine to the VR goggles.

Professor Deng Zigang and his team are now working on a 360-degree self-stabling suspension that will redefine the future of maglev rail transport. With a target speed of 1,000 kilometers per hour, how will these engineers lead technological innovation into the future and redefine "Made-in-China".

Satisfactory result of yet another effort to reduce dependency on imported soybeans for cattle feed.

Up to 70% of the corn seeds are used as cattle feed worldwide. But domesticated corn seeds contain only about 10% protein in average while the wild corns can have as much as 30% even without nitrogen fertilizer.

Chinese scientists checked more than 40000 DNAs in wild corns and finally found the one that controls the amount of protein in seeds. They mixed this gene in the most widely planted corn variety in China and tested it successfully. Not only this gene-modified corn variety produces seeds with significantly more protein, it also requires less nitrogen fertilizer.

It is estimated that every 1% increase of protein in corn seeds used as cattle feed in China can save more than 7 million tons of imported soybeans.


经过十年不懈努力，中国科学院分子植物科学卓越创新中心和上海师范大学科研团队合作，首次从野生玉米中成功克隆出高蛋白基因THP9，并通过杂交实验，有效提高了现代玉米的蛋白含量，这一成果今天（17日）在国际学术期刊《自然》在线发表。

玉米的祖先起源于南美洲，叫做大刍草，种子外面包裹着坚硬的壳，无法直接食用。人类祖先早在9000年以前就开始驯化玉米，逐步把杂草一样的野生玉米改造成了今天的玉米。科研人员实验发现，野生玉米在没有施加氮肥条件下种子蛋白含量都高达30%，是现代普通栽培玉米的3倍，表明野生玉米含有控制高蛋白含量的关键基因。十年来，研究团队提取了超过4万个样本的DNA进行鉴定，最终从野生玉米中克隆到首个控制玉米高蛋白含量的主效基因。

中国科学院分子植物科学卓越创新中心研究员巫永睿介绍，目前玉米已成为世界上最高产的农作物之一，70%的玉米都用作饲料，是最常用且用量最大的一种饲料。由于普通玉米籽粒蛋白含量较低，因此饲料中还需要补充大豆蛋白，然而大豆严重依赖进口，这些成为我国畜禽养殖业的“卡脖子”问题。如果普通玉米蛋白含量每提高一个百分点，相当于每年可以少进口700多万吨大豆。

研究团队在三亚进行了大规模田间试验，将野生玉米高蛋白基因Thp9-T杂交导入我国推广面积最大的玉米生产栽培品种郑单958中，可以显著提高蛋白含量，表明该基因在培育高蛋白玉米中具有重要的应用潜能。同时，在减少氮肥施用条件下，可以有效保持玉米的生物量以及植株和籽粒中氮含量水平，这对于减少化肥使用，保护生态环境具有重要意义。

Chinese researches think that they can convert 25% to 33% of the 1.55 billion mu of saline-alkali land into arable land. If successful, this will increase China's arable land by 380-500 million mu.

That's one excellent news!

China has around 1.919 billion mu (1.279 billion km2) of cultivated land as of 2021.

Imagine how much more food can be produced to feed her 1.4 billion populace when 388 million - 517 million mu (259 million - 354 million km2) of the previously deemed non-arable land can be made arable for agriculture.
