4: Taiwan

Ryan Hass on Taiwan: Has US-China rivalry passed a tipping point? President Biden and President Xi (習近平) agreed at their meeting in Bali last November to dispatch Secretary of State Antony Blinken to Beijing to explore steps that could lend greater stability and predictability to the relationship. Blinken’s trip was derailed when a Chinese spy balloon violated American airspace on the eve of his visit. ......... In the period since, both Washington and Beijing have shifted focus away from managing bilateral relations toward strengthening themselves for long-term competition with each other. .......... The United States and its partners have further tightened China’s access to high-end, dual-use technologies. Washington has secured new military basing access in the Philippines. Rapprochement between the Republic of Korea and Japan has reconfigured the regional strategic picture in America’s favor. And domestically, members of Congress have become more seized with countering China and are working to mobilize the American public on this score.......... Beijing also is working to drive wedges between the United States and Europe. China’s leaders will use upcoming visits by French, Spanish, and Italian leaders to encourage Europe’s strategic autonomy. ......... China also is working to present itself to the Global South as a force for peace, a contrast to American “hegemonism,” an economic growth engine, and a leader that respects each country’s governance model and growth path. This narrative got a boost when China brokered a peace deal between Saudi Arabia and Iran. ........... For some, crossing the abyss means that the United States and China are settling into a new Cold War. For others, it means rising risk of a military confrontation or conflict.......... First, unlike the Cold War, the US and China are not leading two separate systems that are in competition with each other. Rather, they are both enmeshed within a single system and are both deeply interdependent on each other. ......... there is still no public enthusiasm for resolving differences on the battlefield. Leaders in Washington and Beijing remain sober to the reality that conflict would destroy their pursuit of national ambitions.......... a willingness by Biden and Xi to step in and cool tensions whenever the relationship risks overheating. Both leaders have served as a pressure release valve to lower tensions consistently over the past two years. ......... while US-China tensions clearly are rising and risk of conflict is above zero, I would caution against falling prey to doomsday predictions. The sky is not falling and war between nuclear-armed powers is not near .

3D Printing Promises to Transform Architecture—and Create Forms That Blow Today’s Buildings Out of the Water . In the 1880s, adoption of the steel frame changed architecture forever. Steel allowed architects to design taller buildings with larger windows, giving rise to the skyscrapers that define city skylines today. .......... “large-scale additive manufacturing.” Not since the adoption of the steel frame has there been a development with as much potential to transform the way buildings are conceived and constructed. ........... a future in which buildings are built entirely from recycled materials or materials sourced on-site, with forms inspired by the geometries of nature. ........... Clay is an intriguing alternative because it can be harvested on-site— ........ But plastics and polymers could have the broadest application. These materials are incredibly versatile, and they can be formulated in ways that meet a wide range of specific structural and aesthetic requirements. They can also be produced from recycled and organically derived materials. .......... Even common materials like concrete and plastics benefit from being 3D-printed, since there’s no need for additional formwork or molds. ........... Since there is no need for tooling, forms or dies, large-scale additive manufacturing allows each part to be unique, with no time penalty for added complexity or customization. ............ Another interesting feature of large-scale additive manufacturing is the capability to produce complex components with internal voids. This may one day allow for walls to be printed with conduit or ductwork already in place. .

10 Most Exciting SciTech Advances of 2015
"Teixobactin shows how we can adopt an alternative strategy and develop compounds to which bacteria are not resistant." .... Advances in exponential technologies like synthetic biology and genomics are reinforcing the notion that previously unresolvable diseases (cancer, heart disease, Alzeimer's) are in fact resolvable. We are developing solutions to these problems at an accelerating rate, and as we usher in an era of personalized medicine, we will see a dramatic increase in the healthy human lifespan. At my company Human Longevity Inc, our mission is to

make 100 the new 60

. ...... we will soon have the tools to eliminate diseases, create hardier plants, wipe out pathogens and much, much more. ...... Making the first stage of Falcon-9 reusable is a step towards major demonetization of the space industry.
Technologies We’re Excited to See Bloom in 2016 and Beyond
Even high-speed rail systems already seem costly and cumbersome compared to the ability to summon an electric self-driving car on my phone and just be on my way. ...... It’s the idea that any contractual agreement—such as jobs, loans, insurance, and even marriage—could potentially be securely stored and automatically verified by the same technology (blockchain) that makes bitcoin work. This could eliminate the slew of people, businesses, and institutions positioned as financial and legal middlemen, along with their associated red tape. ........ The camera captures light field data simultaneously from all directions and when used for VR, viewers can move around in captured ‘real world’ space, as opposed to recreated computer-generated environments.
Printable Organs Are Closer Than Ever Thanks to Three Bioprinting Breakthroughs
You know what’s even sexier than organ donation? Bioprinting organs. ...... a world in which organ shortages will be a thing of the past....... In March of 2015, 3D Bioprinting Solutions became the first group to successfully bioprint a thyroid gland for a mouse with the intention of transplanting into living mice. Months later, the group announced they had successfully transplanted the bioprinted thyroid and reported that after 11 weeks of monitoring the subjects’ 3D printed thyroid glands, they were in working order with completely restored function. ........ Last week, Vladimir Mironov, head of 3D Bioprinting Solutions, announced his laboratory is ready to start printing a human thyroid gland after their successful experiments on mice. They also have plans to bioprint a human kidney. ...... The team used the company’s own patented bio-printing process to construct the thyroid. They began by extracting stem cells from the living organism via its fat cells. These cells are then mixed with a hydrogel and extruded layer by layer. Once the cells take shape, the hydrogel dissolves. ...... a day when new organs will be readily available for everyone.

Why 3D Printing Will Be a Key Technology in the Next Space Race
Although in many industries mass production techniques still make economic sense—for the ultra-precise, almost bespoke parts in rockets? 3D printing is a great fit. ...... NASA’s latest trial shows 3D printing is set to become an even bigger part of rocket engine manufacturing ..... 3D printed components typically have fewer parts in need of joining and assembling ..... 3D printing also speeds up research and development. Engineers can design a part, print it, test it, find flaws, fix them, and repeat. It takes less time to get from initial design to final part than using traditional casting and the quality is often better. ..... Ceramics are tough materials with a high melting point. They’ve been used as heat shielding on the outside of spacecraft ..... 3D printed ceramics may be used in jet engines or to skin entire jets to withstand the high temperatures of hypersonic flight. ........

3D printing's real value to space exploration may only become clear once we leave Earth.

...... Lacking the luxury of sprawling factory assembly lines in space, 3D printers designed specially for space travel may be one of the pillars of off-Earth manufacturing. Some dream of mining raw materials on asteroids, moons, or planets and converting them into useful things like habitats, machines, and tools. For future explorers to be self-sufficient on the final frontier, they'll need to live off the land.

Zady Makes Me Think Of 3D Printing Somehow


I came across Zady across various social media platforms and streams I peruse regularly when it first hit the "airwaves." Today I looked it up on Google News. It is an interesting twist. Clothitarian? This is like Mark Zuckerberg killing his own meat. What's the source? You want to know the source. It is kind of like blogging. The best bloggers are not professional bloggers but people who are extremely knowledgeable in their domain. They are the source. You should link to them, not just quote them up. Fast food, fast clothing. Fast fashion. Kiva and Etsy.

I kept thinking 3D printing. In that in an era when connectivity is plentiful, information is plentiful, the least you should be able to know is who sewed it up, right? I think it is interesting, I hope it is scalable.

Looks like Soraya Darabi's hibernation is over. She had half a million followers on Twitter. And you thought that was a fluke. And Google Plus launched and she had half a million followers there as well and pretty fast too. How does that work?

And who knew Zady was available as a name! I thought all two syllable names were long gone.

Leap Motion

English: 6 degrees of freedom
English: 6 degrees of freedom (Photo credit: Wikipedia)
Big Data could save Yahoo. Gestures could save Microsoft. But startups stand strong chances in those spaces.

The Most Important New Technology Since the Smart Phone Arrives December 2012
Leap Motion, a small, $70 gesture control system that simply plugs into any computer and, apparently, just works ..... Unlike a touchscreen interface, with the Leap, there's no friction. That sounds trivial, but it isn't. It's the difference between attempting to conduct a symphony with a wand and attempting to conduct the same symphony by sketching out what the orchestra should do next via chalk on a blackboard. ..... Leap operates in three dimensions rather than two. Forget pinch-to-zoom; imagine "push to scroll," rotating your flattened hand to control the orientation of an object with a full six degrees of freedom, or using both hands at once to control either end of a bezier surface you're casually sculpting as part of an object you'll be sending to your 3D printer. .... the Leap can see almost any combination of objects - a pen, your fingers, all 10 fingers at once



This is a leap from 2D to 3D.

One question though, if it picks up gestures well, would you not need to be trained to use it? What if you end up making unwanted gestures? Not everyone can conduct a symphony, you know.
