Scientists have discovered the oldest solar system exactly like the crack eggs minerals

In the latest issue of “American mineralogist, ” an article published in the journal: a team of scientists announced the discovery of a new mineral, the International Mineralogical Association named it Krotite. Based on current analysis, the substance is considered to be the formation of our solar system the most ancient times one of several minerals, but also the formation of early planetary materials, their origins could be traced back to before the formation of the Earth and other planets.

Alexander N. Krot researchers and Krotite new substances

This new mineral was found in a meteorite, the meteorite number (NWA 1934), found in northwest Africa, from the appearance point of view, the shape of the mineral structure of a bit like “a cracked egg. ” The discovery process is quite legendary: New York University, and Dr. Harold C. Connolly Museum of Natural History in the United States Student A. Sweeney Smith in the course of the study, that this was a very, very special, and rich in calcium aluminum Minerals, in addition, can withstand the very high temperature, this temperature environment and is still in the nebula is very similar to the period of the solar system.

Then, this is called “cracked egg ” of the mineral was sent to the California Institute of Technology for further examination of nano-mineralogy, the Institute, Dr. Chi Ma in turn send it to the Los Angeles Museum of National History, the museum’s mineral science Dr. Kampf person responsible for its X-ray diffraction probe found that the main component of the mineral is a low state of calcium aluminum oxide (CaAl2O4), accurate to say is: Ca1.02Al1.99O4. This form of oxides had never been found in nature, but also found that the atomic arrangement of minerals model with a somewhat similar man-made fire-resistant concrete.

That we can learn from this, at least 4.5 billion years ago, what kind of minerals in the results of it, such a study on the origin of our solar system is essential. We need to create at least 1,500 degrees Celsius similar refractory material, to form the basis of this material characteristics of the temperature and pressure, and the formation time, suggesting that this substance is most likely period of the solar nebula is still in formation, that is, krotite our solar system One of the early formation of the raw materials.

Of this meteorite research is still going on, the main direction is committed to figure out under what conditions it is formed and how evolution. In addition to krotite minerals, the egg-shaped structure also includes at least 8 other minerals, of which at least one is currently unknown to the scientific community. The reason that this mineral is named krotite, mainly due to the University of Hawaii researcher Alexander N. Krot the formation of the solar system research on early successes, and its name.

From the look on-line subscription GrouponLive this little thing

We can see as Groupon GrouponLive sub channels, in fact it does, and some distance from the main station.

GrouponLive will focus on the performance ticketing market. Ticket market resources available from the Live Nation Entertainment.

GrouponLive Groupon mother station will not share the user database.

Means that, in order to obtain preferential GrouponLive information, you must apply for a new account, and this new account will appear in GrouponLive recommendation. This is an interesting approach.

Subscription

This basic action has become the site came into contact with the consumers buy the starting point. With the development of buy site, users began to notice the changes to the Inbox.

One to one days from the day a few letters

As to the letter from a few

For profit, multi send some message, for profit, multi-release several products, as a businessman right. But taking into account market conditions, I think this may not be considered good.

The benefits of day one

Success is to also buy out “the lowest price, highest quality.” In the domestic “war thousands of groups,” the pattern in order to succeed must show the best things. From this point of view, “one day” to maintain a website buy “professional teacher recommended” image.

Analogy, a friend, every day you come to a call, “Brother, today I found a good place.” And another friend, every day you come to a few calls “Brother, I have also found a a good place. ” Who would you feel more insight into who is more attractive it?

Suddenly, the old saying to buy Web product manager on the heart, reflected in the user’s inbox.

One day a few trade-offs

Restaurants buy from the earliest, to today’s brand-name home, electronic products, popular magazines, priceless lottery, only to my surprise, no less than corporations. The change this rich material and cultural life of the people have a great contribution, but problems follow. Consumers want a more accurate recommendation.

Now none of the smart match buy site user can reach the recommended case, may as well give the user the right to choose.

Look at how this method?

You can recommend some kind of master products, but let me choose subscriptions of interest. For example, I wanted to see the restaurant’s promotions, then let me check the restaurant, the other content can be directly followed the form of text, or simply do not appear.

Subscription is a small, but buy on the site is easy to reflect the lower points in this little things.

New traditional portals – AOL devil program

AOL in the past for a long time is a very powerful Internet services and media company. But in the past decade, gave its AOL lot of money in the closed model has been proven out of touch with the times.

Below is a 2001-2009 the number of curves of AOL subscribers will be able to describe the problem. Time Warner in 2000 and just over a year after the merger, AOL’s subscription began a sharp decline in the number of users. AOL Time Warner in 2009 from the independent. After separation of AOL’s business conditions are still deteriorating net income -7.83 2010 AOL billion this year, the number of only 3.6 million subscribers.

AOL greatly in opening the new model the impact of the Internet when the new CEO Tim Armstrong took office last month, two years after joining AOL, Google, Armstrong was an early member of the management team responsible for advertising sales in North America. After taking office AOL CEO, Tim’s main goal is to save AOL’s decline and put it back into a high-quality content, digital media companies.

The acquisition of “Huffington Post ” After, Armstrong adjust management, streamlining the product, re-designed home page to display ads more effectively. The business from the previous quarter judging the effectiveness of these initiatives are already beginning: Online advertising revenue grew 4%, for this part of the proceeds for three years AOL has been losing streak, it is a good sign.

From the “devil project (Project Devil) ” Start

AOL devil project is the first step in change. Devil project home page, white on red says “there is no reason now the website looks and 15 years ago. ” The following picture also clearly shows the devil project innovation.

Devil project will include the following aspects:

Refreshing the page. The starting point is the devil project as a whole, the entire page, the page appears on the role of each element must be very clear. Page content is the focus of advertising to do so-called added, the page must be simple, clean and elegant.

More advertising. Traditional portal site’s home page full of very small ads to text links, flash and other new show. This project will revolutionize the devil, to provide greater, more flexibility and beauty of the advertising space – more like a large appear in the magazine ads, but also to read the content for more friendly.

More interactive. Advertisers and users expect all interactions are done in the current page.

Less interference. Devil project, only one ad per page, usually after the traditional site click on the ads into a page, all links on the page will direct users to more elsewhere. AOL will completely abandon new projects such practices.

Better experience. Most online advertising is aimed to spread the contents of the user’s attention to the ads – greatly affect the user experience. Devil project will ad as part of the overall experience presented to the user.

One of the biggest action is to the number of ads from the AOL home page for a dozen cuts – for users to more easily notice them and click into the existing ads, for advertisers, they are more eager to get this only Some one advertising. Now, traffic is already advertising the previous 40 times.

Devil project eventually would like to see the effect to enhance the ads, including click-through rate increase of 1.9 times the residence time of the user’s ads increased by 3.4 times to 47 seconds and so on.

Innovation in the traditional site of the user experience

AOL ways to subvert the devil his project. While page views and speculation entirely dominated by “AOL Way” had a lot of controversy, but last year was acquired TechCrunch point of view, experience a brief decline in the quality of content, it is now rebounded, and even better than before the acquisition ;, “Huffington Post” is now user-generated content from a web-based editorial team develop into a professional media – these are not entirely one-sided pursuit of hype and PV.

AOL’s main station was typical of the traditional portal websites. Most of the traditional class Web portal and AOL have the same problem: the home has become increasingly difficult to obtain useful information to facilitate readers, for advertisers, it is not the best way, because basically we will put a dozen in one page ads as spam.

AOL has been aware of the crux of the problem, have taken measures: innovative presentation of content and advertising, while the content quality and user experience first.

Prior to AOL for a number of innovations, Gawker’s the Gizmodo, LifeHacker, Kotaku and other sites has also been adjusted, it is also changing the presentation, highlighting the content of the article. Although the public on the Gawker website of the evaluation of mixed, but to reveal the contents of this point, actually more efficient than before.

AOL and Gawker’s revision in a way that also represents a clear trend – for generated content sites, the content itself and the user experience is the most important aspects, it is important to even the most traditional news site must also consider how to organize content for a better experience for users.

On an age of giants in the new Internet environment, the Jedi can rebirth? Is indeed a topic worthy of attention and consideration.
