!wOw!

Unfortunately, it doesn't work like that. Every cell type in all organs need the entire genome to work. Only difference is that each cell type interpret the genome slightly differently. For instance, some parts of the genome is silenced in brain cells, whereas the same parts of he genome become active in stomach cells. So you need the entire genome to work, no matter what kind of tissue you want to grow.
This is why I am somewhat against GMO. In the GMO - nonGMO spectrum, I am a moderate anti-GMO. Those pro-GMO people claim that one gene encodes one protein and it would be the same no matter what organism. They either misunderstand it or try to mislead people. No one knows how cells would silence/unsilence a part of the gene. If different cells within a single body interpret genes in different ways, how do you know how cells in a completely different species would interpret the genome?

An easy way to clone human is to gain a fertile embryo and as it splits into two cells you separate the cells into two individual embryos the process is the same as natural twins since you could say that identical twins are clones.
As for transplant of memory and other Sci-Fi ideas there just that Sci-Fi. Recent studies suggest that our brains utilizes quantum mechanics within our thought process(Eureka moments) but even clones does not develop identical finger prints and/or neural pathways so identical thought patterns is out of the question.

Uh... That's just normal birth of monozygotic twins. All you are suggesting is to "artificially induce" the development of twins. Not cloning. Cloning requires a single copy of DNA being copied into a new individual. In your case, the genetic information of the new individual still comes from two sets of DNA.
Plus, the goal of cloning is to eventually grow organs for patients. In order for your strategy to work, everyone will have to have twin. That means actually cloning human in mass scale. Then you will have to kill your clone to harvest organs. And this can only be done once since your clone can only be harvested once. Highly inefficient and highly highly unethical...
Again, the goal is not to clone human. It's to understand how different cell types control silencing and unsilencing of the genome. And eventually, grow organs for patients.
I can't stress enough: no human cloning. I cringe every time people mention human cloning. It only damages the image of scientists, which impede the progress of actually important research. If people begin making connection to human cloning when we talk about actual "cloning", all this crazy stuff about human cloning will come to mind. What will happen is that people will begin to resist these researches, slowing down the progress. That means loss of countless patient lives, which could have been saved if research is allowed to progress smoothly. So guys, do yourselves a favor, stop talking about human cloning.
They were able to design a world beating switch used in their record maintaining Tianhe-2 supercomputer, so there must be a lot of talent.

Here is an interesting idea from three Chinese scientists.
Engine uses debris as propellant in concept to clean space junk
Space debris is a pressing problem for Earth-orbiting spacecraft, and it could get significantly worse. It threatens satellites and craft; now scientists at Tsinghua University in Beijing are looking at an approach that could draw more attention among those looking for solutions.
Space debris refers to an unhappy situation resulting from human activities in the space—defunct rockets and satellites, ejection from rockets and spacecraft, the waste of and products of collisions from other debris.
A collision between and an operating satellite can result in the loss of equipment worth hundreds of millions of dollars, along with the general business disruptions..... to read more .

That still requires grinding the space debris into smaller pieces in order to be use as propellant? But wouldn't you still be spewing out the same debris back into space assuming one is still traveling around Earth's orbit?

I believe what they are proposing is grinding the junk down to a powder then ionize the powder that can be used as propellant. Basically the ionized powder would be smaller then a grain of sand.
China Surpasses Japan as Asia's Top High-Tech Exporter
China accounts for 43.7% of Asia's exports of high-tech goods

China has brought to an end Japan’s dominance of Asia’s high-technology exports, according to the Asian Development Bank.
China’s share of Asia’s exports of high-tech goods such as medical instruments, and aircraft and telecommunications equipment rose to 43.7 percent in 2014 from 9.4 percent in 2000, the ADB said. Japan’s share slid to 7.7 percent last year from 25.5 percent in 2000. Southeast Asian nations including Malaysia and Philippines also lost market share.
The shift marks China’s success in boosting innovation and technology as key drivers of its economy as it seeks to move up the manufacturing value chain. Low-tech goods accounted for 28 percent of China’s exports in 2014, compared with 41 percent in 2000, according to ADB’s Asian Economic Integration Report 2015 released Tuesday.
"China has made inroads in taking more and more hi-tech manufacturing onshore even as a lot of critical components are still imported from other countries," said Frederic Neumann, co-head of Asian economic research at HSBC Holdings Plc in Hong Kong. "It’s becoming highly competitive, with highly skilled labor and we’re seeing increasing research and development moving into China."
China-Made Drones
China-made drones, smart phones, and even high-speed trains have become internationally competitive and the number of enterprises in the high-tech manufacturing sector has tripled to almost 30,000 from less than 10,000 in 2000, Shang-Jin Wei, ADB chief economist, said in an e-mail.
“We are seeing some signs of success in some industries,” he said. “But China is still not a global technology leader like the United States or Germany. What we are seeing is that China is catching up very fast on the ’standard technology’ products and is beginning to do some innovations of its own.”
China also leads in exports of low-tech goods such as textiles, food and beverages, and wood, pulp and paper products. It had a 55.4 percent market share in 2014, followed by India with 9.4 percent.
Cross-border production networks -- trade in parts and components and final assembly -- have strengthened regional interdependence, as seen from increasing intraregional trade shares, the ADB said. Asia’s intraregional gross exports have increased about 3.6 times from 2000 to 2011, it said.
Economic Zones
Special economic zones can be a driving force for increased trade, investment, and economic reform in Asia at a time when the region is experiencing a slowdown in trade, provided the right business environments and policies are put in place, the ADB said. In developing Asia, countries with economic zones attract significantly more foreign direct investment, corresponding to 82 percent greater FDI levels, it said.
Separately, while the impending increase in U.S. interest rates could raise capital flow volatility, it is not expected to rattle the region’s markets as it did in 2013, the report said. Still, managing potentially volatile capital outflows remains an important issue for the region -- especially given rising risk premiums and depreciating currencies, it said.
