Smartphone Security Could Be Based on User Behavior
With implicit identification, aka implicit authentication, your smartphone would shut down after recognizing it was lost or stolen based on how the new user was fiddling with its functions. Larry Greenemeier reports
Transcript hided
Apple’s new Touch ID biometric fingerprint sensor has people thinking about new ways to secure their smartphones.
One approach in the works is “implicit identification,” sometimes called “implicit authentication.” Instead of a password or fingerprint, your phone would recognize you by your behavior.
According to an article on the global business news outlet Quartz, researchers at the Palo Alto Research Center, U.C. Davis, Carnegie Mellon and elsewhere are investigating implicit identification for mobile gadgets. Such systems would ID you based on where you go measured by the phone’s GPS, apps you use and Web sites you visit.
Add phone call, text and e-mail patterns to the mix as well. Implicit ID could even factor in your typing skills to verify your identity.
Of course, none of this keeps your phone from being stolen. And a thief might be able to access some of your info before your phone figures out what’s happened and hits the kill switch.
Implicit authentication likely won’t banish passwords. But it could be used alongside them to help your smartphone cover your digital assets if they fall into the wrong hands.

The Most Common Tree in the Amazon
[attach]131289[/attach]
The Amazon remains a mystery to botanists, who haven't known how many kinds of trees live in the extremely diverse forests or even what species is most common. Turns out, it's a slender palm called Euterpe precatoria. After counting up tree species from 1170 research sites studied by hundreds of scientists, a team extrapolated the number likely to exist across the entire region. They estimate that Amazonia has about 16,000 species of trees (although they admit the statistical model has some problems, such as not accounting for environmental preferences of various species). Remarkably, half of all the trees belong to only 227 species that dominate in various regions, probably because they resist diseases and herbivores, such as insects. Others may have been planted by humans before Europeans arrived. Many species—11,000—are extremely rare, accounting for a mere 0.12% of trees. Half of these are probably rare enough to be considered globally threatened and may go extinct before they are discovered.

Armageddon 2
[attach]131288[/attach]
Want to know if that meteor that just struck Earth has a companion? Take a look at its trail. A new study shows that images of a meteor’s streak through the atmosphere taken by Earth-gazing probes, including weather satellites, can pin down the object’s orbit, enabling scientists to check and see whether another planet-threatening object is traveling in the same trajectory. The finding comes thanks to the almost-20-meter-wide meteoroid that blazed into Earth’s atmosphere in February and exploded over Chelyabinsk, Russia, damaging buildings there and injuring hundreds. Soon after it streaked over the country (main image)—in some cases, mere minutes later—a number of satellites snapped views of the trail from on high (example, inset). Analyses of those images enabled researchers to confirm the trail’s location, height, and orientation, which in turn allowed them to determine the orbit that the object had been following before it slammed into the atmosphere. The orbit estimated using satellite data alone reasonably matched the one estimated via ground-based videos, the team reports online today in the Proceedings of the National Academy of Sciences. In situations where objects enter Earth’s atmosphere in more remote locations—over the ocean far from land, for example—satellites may be the only sources of data that could be used to determine an object’s orbit. The threat to our planet from an object’s orbital companions isn’t merely an abstract concern, the researchers contend: One recent study suggests that about 15% of the asteroids that cross Earth’s path may be part of double or triple asteroid systems.

Fields of gold
Research on transgenic crops must be done outside industry if it is to fulfil its early promise.
[attach]131290[/attach]
It was 30 years ago this month that scientists first published the news that they could place functional foreign genes into plant cells. The feat promised to launch an exciting phase in biotechnology, in which desired traits and abilities could be coaxed into plants used for food, fibres and even fuel. Genetically modified (GM) crops promised to make life easier and nature’s bounty even more desirable.
As a series of articles in this week’s Nature explores, things have not worked out that way (see page 21). The future matters more than the past, but when it comes to GM crops, the past is instructive.
Soon after the 1983 breakthrough, biotechnology companies developing GM crops became hugely attractive to investors. Calgene in Davis, California, for example, developed the Flavr Savr tomato — engineered to remain firm after ripening — which captured attention, especially when the iconic Campbell Soup Company invested in its development. Like many at the time, Campbell’s was fascinated by the promise that tomatoes could be ripened on the vine to accentuate their flavour and still make the trip to the supermarket and the dinner table without turning to mush.
字数[206]
【Time 5】
In early 1992, analysts predicted regulatory approval for the GM tomato within a month, and a market of at least US$500 million a year. But less than a decade after their birth, GM crops were already facing a difficult adolescence. What was once deemed biological wizardry was increasingly being labelled Frankenfood. Consumers in Europe were bristling at the aggressive marketing of GM giant Monsanto, based in St Louis, Missouri. The Flavr Savr suffered more than a year of delays at the US Food and Drug Administration, and Campbell’s began to state that it had no intention of putting the tomatoes in its soups without approval from the public. What had gone wrong? According to one analyst quoted at the time, the biotech sector had failed to prepare consumers appropriately: “Now, they realize that they have to be articulate and educate an uninformed public.”
The Flavr Savr was approved in 1994 but never took off commercially. In the meantime, the biotech industry had shifted much of its attention to traits that aimed not to delight consumers, but rather to increase farm yields. Herbicide-tolerant and pest-resistant crops proliferated in the United States and more than two dozen other countries. GM organisms were to become agricultural tools.
In many places where they are planted, these GM crops have replaced conventional planting almost entirely. Yields and profits have increased, farmers have been generally happy to adopt the transgenic seeds and the technology has even made good on some of its promises to help the environment by reducing the amount and variety of pesticides needed.
GM crops, of course, still face a public-relations problem. Fears of the unfamiliar and ‘unnatural’, and concerns about health or environmental impacts, have frequently prevented approval and adoption of the crops, especially in Europe, where protesters have destroyed experiments. The United States, the world’s most active user of GM crops, has seen renewed backlash as calls grow for foods with GM ingredients to be clearly labelled.
字数[326]
【Time 6】
The analyst who spoke of an uninformed public may have been correct in 1993, but such a claim no longer applies. People are positively swimming in information about GM technologies. Much of it is wrong — on both sides of the debate. But a lot of this incorrect information is sophisticated, backed by legitimate-sounding research and written with certitude. (With GM crops, a good gauge of a statement’s fallacy is the conviction with which it is delivered.)
Armed with misinformation, debaters have taken to the streets, the supermarkets and social media. With a topic as sensitive and dear to people as the food they eat and give to their children, those who play to the fears, concerns and uncertainty surrounding GM crops often seem to have the upper hand. And the fears are entwined with mistrust of the seed companies. Supporting GM crops can seem a thankless job: it is worthwhile to stand up for good science and the promise that it holds, but defending profit-hungry corporations feels less rewarding.
Still, there is reason to stand up for the continued use and develop ment of GM crops. Genetic modification is a nascent technology for which development has moved very quickly to commercialization. That has forced most research into the for-profit sector. Without broader research programmes outside the seed industry, developments will continue to be profit-driven, limiting the chance for many of the advances that were promised 30 years ago — such as feeding the planet’s burgeoning population sustainably, reducing the environmental footprint of farming and delivering products that amaze and delight. Transgenic technologies are by no means the only way to achieve these aims, but the speed and precision that they offer over traditional breeding techniques made them indispensable 30 years ago. They still are today.

Hot News: Fusion Researchers Recommend ITER Design Tweaks
Researchers are recommending that this key part of ITER, an exhaust system known as the divertor that must withstand high temperatures, be coated with tungsten instead of carbon.
[attach]131291[/attach]
Scientific advisers to the ITER fusion reactor project have recommended several key changes to its design that could increase technical risks—but also smooth the path to producing excess energy. The recommendations, made last week by ITER’s Science and Technology Advisory Committee (STAC), will have to be approved by the full ITER council in November. But if approved, as expected, “the chance of surprises later is reduced,” says Alberto Loarte, head of ITER’s confinement and modeling section. “The risk will pay off.”
ITER, being built in France by an international collaboration, aims to show that nuclear fusion, the reaction that powers the sun, can be controlled on earth to produce energy. But reaching that goal involves heating hydrogen gas to more than 150 million°C so that hydrogen nuclei slam together with enough force to fuse. To do this, researchers are building a huge doughnut-shaped container called a tokamak to confine the ionized gas—or plasma—using enormously strong magnetic fields. ITER’s goal is to coax the plasma to produce 500 megawatts (MW) of heat, 10 times the 50 MW of power required to heat the plasma; this multiplying effect is known as a gain of 10.
The most significant change decided at the STAC meeting concerns a structure at the base of the tokamak vessel called the divertor. Its main function is to remove the helium that is the “exhaust” gas of the fusion reaction. The divertor is the only part of the vessel where the superhot plasma actually touches a solid surface, so it has to be able to absorb huge quantities of heat, as much as 10 MW per square meter of surface.
Existing plans call for making ITER’s first divertor with an outer layer of carbon. This is the safe option: Carbon is well proven in tokamak interiors; it can easily withstand the temperatures; and if any is blasted off into the plasma, it doesn’t affect the performance very much. The problem with carbon, however, is that it happily reacts with hydrogen, binding atoms into its structure. This wouldn’t be a problem during the early phases of ITER operation when researchers plan to use simple hydrogen or helium in the machine to get the hang of how it works. But a carbon coating could be a huge problem in later phases, when researchers plan to switch to real fusion fuel—a more reactive mixture of the hydrogen isotopes deuterium and tritium. Tritium is radioactive and so needs to be carefully controlled and accounted for. Nuclear regulators would never accept a divertor material that absorbs tritium and so makes it impossible to locate.
To address that problem, planners had proposed running ITER for several years with the carbon-coated divertor, and then switching to one made of tungsten. Tungsten has the highest melting point of any metal: 3422°C. That should be fine for withstanding the heat produced during normal, steady ITER operations. But any unexpected bursts of heat could potentially melt the divertor, and tungsten—unlike carbon—instantly poisons the plasma, bringing fusion to a halt. So ITER’s operators would have to run the reactor much more carefully with a tungsten divertor, not pushing it to limits where the plasma might become unstable.
Despite this drawback of tungsten, STAC has recommended that ITER be built with a tungsten divertor from the start. “It was not an easy decision,” says STAC Chair Joaquín Sánchez, head of Spain’s National Fusion Laboratory in Madrid. The decision was made after years of research at other tokamak laboratories, in particular the Joint European Torus (JET) at Culham in the United Kingdom, which is the closest machine to ITER in size and design. Several years ago, JET researchers refitted the reactor with a tungsten divertor and beryllium lining (as ITER will have). After a year of testing, they confirmed that this “ITER-like wall” worked well enough not to cause problems for ITER.
Although some fusion researchers think that it would be safer to start ITER with a well understood carbon divertor, allowing them to push the reactor to extremes in search of high performance, starting with tungsten has advantages, too. Changing divertors is a complex process that would take many months. In addition, once operation with deuterium-tritium fuel has started, the interior of the vessel becomes radioactive (or “activated”), making it much harder to modify internal components. “If we start with tungsten, we save the cost of the change,” Sánchez says. “We know tungsten will be more difficult, but we will start learning earlier in the nonactivated phase and if there is a problem we can send people inside to fix it.”
The other design changes concern two separate magnetic coils to be inserted inside the reactor vessel to fine-tune control of the plasma. ITER’s main plasma-confining magnets are outside the vessel and act as something of a blunt instrument. About 5 years ago, researchers highlighted the fact that operators would have difficulty keeping the vertical position of the plasma steady, and so proposed some extra magnetic coils on the inside.
In addition to those for vertical stability, researchers proposed installing a second set of internal coils to combat a troubling phenomenon in superhot fusion plasma called edge-localized modes, or ELMs. ELMs occur when energy builds up in the plasma during fusion and then bursts out of the edge unpredictably, potentially damaging the lining or the divertor. The second set of coils deploys a magnetic field to roughen up the surface of the plasma so that it leaks energy at a constant rate rather than in erratic bursts.
Anything inside the vessel is subjected to extreme heat, radioactivity, and magnetic forces, so researchers had to persuade STAC that these two sets of coils could be made resilient enough to survive. “There was some reluctance in STAC and the ITER Organization because of the technical issues of installation,” Loarte says. Experiments at other labs around the world reassured them. “The results obtained were very positive,” he says.
STAC also took a hard look at the delivery schedule of components for ITER. The original plan called for everything—heating systems, instruments, ELM mitigation—to be in place when ITER is completed in 2020. But delays have meant that some items will be arriving later. “We needed to redo the schedule with a logic consistent with [achieving deuterium-tritium operation] faster. It was not consistent before and that led to criticism,” Loarte says. “Now we have to do the organizational part, which is not simple.”

【ITER - International Thermonuclear Experimental Reactor】
“国际热核聚变实验堆”，是一个能产生大规模核聚变反应的超导托克马克，俗称“人造太阳”。是目前全球规模最大、影响最深远的国际科研合作项目之一。
这一项目的目的是利用核聚变解决人类未来能源问题。与不可再生能源和常规清洁能源不同，聚变能具有资源无限，不污染环境，不产生高放射性核废料等优点，是人类未来能源的主导形式之一。合作承担ITER计划的七个成员是欧盟、中国、韩国、俄罗斯、日本、印度和美国，这七方包括了全世界主要的核国家和主要的亚洲国家，覆盖的人口接近全球一半。合作协议于2006年签署
【Nuclear fusion -- 核聚变】
与原子核裂变释放的裂变能（即原子弹的原理）相比，两个氢原子核聚合反应后释放出的聚变能更加迅猛（氢弹原理），这也是宇宙间所有恒星（包括太阳）释放光和热的能源
人类已经能控制和利用核裂变能（连朝鲜都可以开放核武器了，看来人类已经掌握的相当好了），但由于很难将两个带正电核的轻原子核靠近从而产生聚变反应，控制和利用核聚变能则需要历经长期的、非常艰苦的研发历程。在所有的核聚变反应中，氢的同位素---氘和氚的核聚变反应（即氢弹中的聚变反应）是相对比较易于实现的。
考虑到氘和氚原子核能产生聚变反应的条件，若要求氘、氚混合气体中能产生大量核聚变反应，则气体温度必须达到1亿度以上（文中提到是1.5亿度，偶滴神啊）。在这样高的温度下，气体原子中带负电的电子和带正电的原子核已完全脱开，各自独立运动。这种完全由自由的带电粒子构成的高温气体被称为"等离子体"(即文中的“Plasma”)。因此，实现"受控热核聚变"首先需要解决的问题是用什么方法及如何加热气体，使得等离子体温度能上升到百万度、千万度、上亿度。托克马克就是现在的解决方案
【Tokamak -- 托克马克装置】
是一种利用磁约束来实现受控核聚变的环性容器。它的名字Tokamak 来源于环形、真空室、磁、线圈。最初是由位于苏联莫斯科的库尔恰托夫研究所的阿齐莫维齐等人在20世纪50年代发明的。托卡马克的中央是一个环形的真空室，外面缠绕着线圈。在通电的时候托卡马克的内部会产生巨大的螺旋型磁场，将其中的等离子体加热到很高的温度，以达到核聚变的目的。

one of the changes mentioned above is the design of divetor, which is at the base of tokomok.
the coater of the divetor once was designed to use carbon. carbon is okay at first but proved to be problematic in the following phrase.
researchers planed to switch carbon to tungsten after a few years of running carbon, but tungsten divetor still has some flaws.
researchers decided to use tungsten at the start ( not switch to tungsten from carbon) after years of researches.
Switching is complext, and starting with tungsten has advantages.
the other design changes include the extra magnetic coils on the inside.
a second internal coils is aimed to solve a problem called ELM
changes also include the delivery schedule of components for ITER.

Then descrine the advice made in STAC to the ITER.
The old plan is safe in the start but have some problems in the later pharse.
One solution is to drawback to the tungsten.
So the recommendation is to build the ITER with tungsten at start.
Although this is a good plan,but the process is too complex and may cause some problem.
Other design can also achieve this goal.But some people oppose it for several reasons.
But this plan is necessary.

ITER now faces several problems: one is the component that used for absorb the exhast generated and was the only part touched the surface. It had to be heat tollerating, as the internal will be very hot to thousands degree. One proposal is to use Carbon, it will not give bad damage even if reached its melt point, but the shortage is it will absorb the xxx, in the 1st phase it would not be a problem, but during the 2nd phase to simulate sun's power reaction it would cause the issue; one proposal is to use the Tanguren, which has the highest melt point. But there're still some concerns.
Also need to keep the vessel steady horizon, magnat material might be put inside.
Due to those concerns, the plan has been delayed and there're several consideration that should be taken.

1. Ep are the most common tree in Amazon, & lots of rare speices would go extinct before discovery.
2. Scientists found out a method to track a object's orbit into earth atmosphere using statelites.
Significance of the findings
3. prediction for GM foods appears shiny, based on advantages of them. However, things never happened.
1) PR cirisis: offer for GM foods delayed in certification bristles the customers.
--> GM tech were spread in farming crops.
2) PR problem still exists: unnatural--> GM foods need to be labeled
3) > reasons for GM can be a thankless job: not profit-driven.
> reasons that GM will still continue to develop: advantages & commercilization quickly.
debates are not object always. but still GM will continue to develop thanks to profit-driven features and other advantages.

time4 1:21 .The news that the scientists can place functional genes into palant cells was published 30 years ago.Many investors made good prediction on this market.However that result turns out unlike the thought.
time5 2:04 .The products faced a crisis since consumers can not distinguish natural crops from the GM crops.The investors fail to educate people whether the GM crops are healthy and "natural".In the US,where consumers consume the most GM crops,those food are required to be clearly labelled.
time6 2:09 .Those protester who have incorrect knowledge about the GM crops went out against the GM crops.It is good for the public to call for more information about these crops before they acturally buy them.But those investors feel hungry in the profit.The proceeding research become profit-driven instead of its original aims.
time7 7:54 .intriduce the ITER fusion reactor.It needs quite high temperature to provide enough force.
There are some changes in the design,
The most significant change is the material chosen to build the vessel.The author shows the advantages and drawbacks of the original material-carbon and the optional material-tungsten.Because changing divertors is a complex procss so it is better to build the vessel with the right material at first.
Other changes include installing a second set of internal coils.
The original schedule has to change because some items will be arriving later.

The trans-genetic food was be paid high expectation but in the first decade it not so welcomed by people. Because of the postpone approval by the government and the little willingness of the consumers, the GM failed to get good revenue from the very start.
But the GM is considered as a agriculture tool now. It can help farmers to improve the yields. But the fear to the unnatural technology and products are still exist,especially in Europe.

ITER faces some changes accompanied with risks and breakthroughs. The first one is with the carbon-coated divertor, which cannot absorb a radioactive Tritium, so that reseachers plan to switch to tungsten divertor. However, tungsten also have defects: it may melt in bursts of heat, causing the fusion to halt. But scientists think the benefits of tungsten outweigh its downsides. Tungsten could help to save cost and better to control without causing problems. Also changes take place with the vertical stability and response ability of coils in the reator.

There is a ITER project, aiming to control nuclear fusion to creat energy(ITER). This article discusses some of obstacles they are facing.
For example, coax the plasma to produce high level of heat, the issue of carbon outlayer of divertor. Scientists plan to replace the carbon outcoating with one made of tungsten.

Time2 30’ Scientists still don’t know how many kinds of trees in Amazon.
Time3 44’ the scientists want to know whether the meteor has a companions? The scientists contend that the asteroid may be part of double or tripple asteroid system.
Time4 1min the scientists research the GM crops which promise to make life easier and attractive many investors.
Time5 1min 30 the GM crops face a difficult situation which mainly come from the uninformed customers. Then the industry put more focus on increasing farm yield, rather than delighting customers, with the following, the GM crops has gradually replaced the traditional crops. But in order to figure out the customers’ problem, all the GM crops are labelled in the markets.
Time6 1min 30 there are some incorrect information on both sides of debates, but the incorrect information is sophisticated. But there are still existing some reason for developing the GM crops, on one hand, it has moved into commercialization, on the other hand, it can resolve feeding questions with large population growing.
Time7 6min the ITER is the main purpose to control the powers of sun to produce energy,
The key part of ITER known as divertor is exhaust the gas of infusion reaction.there are changes of design in ITER. On one hand, in order to address carbon problem, tungsten is coated with the divertor, instead of carbon. On the other hand, two magic coils is to be insered. At last, the need to keep the dilivery schedule for ITER is consistent.

Speed
Timer 2: 1'48"
According to a big research conducted by hundreds of scientists, Amazon has approximately 16,000 trees, 11,000 (0.12%) of which are endanger even facing extinction. Among these 16,000 trees, only 270 are the domain ones mainly because of their resistant abilities toward insects and deceases.
Timer 3: 2'25"
Scientists invented a way to monitor the orbit of a meteor when it enters to the atmosphere of the Earth by XXX. This discovery greatly helped determine XXX. The entry of a meteor to Russia caused great damage to buildings & XXX. It was proved that the observation from scientists' new way & the pic from the satellites are accordance. Also
Timer 4: 2'30"
Scientists have managed to implant foreign genes to plants and therefore make certain plants have the features that are benefit for humans and make our lives easier. However things did not go as the way they predicted. Some scientist created a kind of tomato that are not going bad after ripened. Buyers were amazed by this technique, which shows great economical potential.
Timer 5: 2'20"
GM was considered a great breakthrough in biotech and predicted to bring 5 billion? for the industry. However since the SF company did not put GM into mass production and has been upset consumers. It is now facing adolescence. General public are not educated enough to accept this gene-modified tomato. However farmers like it since it greatly increases production and shows high resistance to insects, which lowers costs. Though in Europe, GM is facing big obstacle, it is fairly popular in the U.S..
Timer 6: 2'52"
Since the general public have more access to information, the GM does not seem that bad. However debaters have taken the street and spread negative information about the GM, especially health & environmental concerns, some of which are gratuitous. At the same time some companies are too focused on profits and do not grant thorough research to these gene-modified products, which may cause problems.
Obstacle
Timer: 5'36"
The old ITER has several problems. When carbon used, it is fine in the early phase, but turns into radioactive in later process. When Tungxxx used, it can be unstable.
SCT/SAT? suggested ITER to redesign and rebuild the whole thing. The scientists designed the new ITER in a donut shape. It has disadvantages, but can be fixed. It might take many months to finish and the SCT? has reservations about the installation. But scientist are confident that those problems can be resolved.

Time2(1’01) In the past, nobody know how many trees in amazon rainforest and what is the most common tree in amazon rainforest. Recently a team of scientists have discovered the solution to these problems, although with some model flaws.
Time 3 (1’59) A meteor has invaded in earth’s atmosphere and destroyed some buildings in Russia. Scientists used the image taken by the satellite combined with those records from ground to estimate the movement of the meteor before it has stroke into earth’s atmosphere. Because it is not the only meteor but the whole system
Time 4 (1’13) The technology change in genetically modified field has made a breakthrough and people look forward to it. Such GM food made people’s life easier and has influence on the food company’ s performance. For the genetically modified tomato, tech can foster them with good taste without turning into mush.
Time5(2’11) Even though the GM seem to be successful soon, the unfamiliar problem has inhibited the development of GM. Without approve, GM company transferred their focus to use the GM tech as an agriculture tool to increase the production of corn. Such unfamiliar problem cause many people move against GM food, even in US GM food needed to be labeled
Time6 (2’09) there are many misinformation about transgenic food, so there are many debate about GM food. What’s worse, the research of GM was driven by the profits, which limit the range and direction of the research.
Obstacle (8’58)
Scientists are trying to modify some devices on the ITER, with those changes the risk will increase but the experiment will become smoother.
They want to add a device to emit the exhaust gas, but such device is susceptible to those highly active gases.
In addition, an out layer also planned to be placed on ITER, but the carbon out layer is very easy to react with the H gas.
Other two devices as the coils will also be added into the ITER, to make it more stable and prevent a sudden emission of gas.

A:
P: identify the changes and the solutions
S:
+put forward the main idea
+one change:The most significant change decided at the STAC meeting concerns a structure at the base of the tokamak vessel called the divertor.
-Existing plans call for making ITER’s first divertor with an outer layer of carbon
-To address that problem, planners had proposed running ITER for several years with the carbon-coated divertor, and then switching to one made of tungsten.
-Despite this drawback of tungsten, STAC has recommended that ITER be built with a tungsten divertor from the start.
-Although some fusion researchers think that it would be safer to start ITER with a well understood carbon divertor, allowing them to push the reactor to extremes in search of high performance, starting with tungsten has advantages, too.
+the other one: The other design changes concern two separate magnetic coils to be inserted inside the reactor vessel to fine-tune control of the plasma.
-Anything inside the vessel is subjected to extreme heat, radioactivity, and magnetic forces, so researchers had to persuade STAC that these two sets of coils could be made resilient enough to survive.
+STAC also took a hard look at the delivery schedule of components for ITER.

GM crops was developed to increase the yields of crops but now faces the doubts from the publics.
GM crops replaced convention crops in some places entirely.
GM crops researches are driven by profit and are now more toward the taste of customs not the yield.
Public who are now in a information world have misinformation of GM crops and oppose the GM crops: eg. EU and US
GM is still useful but need to change
Obstacle
1. The introduction of the new technology with considerable risks
The advantages: 1:10 energy production
The risks: the detail of the reactors: fuel materials: hydrogen gas
Carbon could react in the second stages while T could prevent the problems
Problems with T: when melting, T could poison the fuel materials
2. The attempt of T reactors
T reactors should be built from the start: the internal vessels become radioactive
Deal with the internal coils which are radioactive.
Edge –localized modes.
