Scientists in Shenzhen said they have applied a new genome sequencing method to detect genetic defects among in vitro fertilized embryos, which can lead to a higher chance of having healthy babies for couples who suffer infertility.
The first baby screened with the new method - who was born in Hunan province on Aug 24, 2012, weighing 2.4 kg - is now at normal development, BGI Shenzhen announced at a news conference on Monday.

Scientists removed seven to 12 cells from morphologically normal human embryos five days after fertilization in vitro for preimplantation sequencing. Then they used the latest DNA technologies to detect abnormalities, which will determine the genetically intact embryos.
“The preimplantation sequencing may have a crucial role in improving the efficiency and safety of human assisted reproduction,” said Du Yutao, vice-president of BGI Health Group.
Gabor Vajta, a professor from the University of Copenhagen, said the discovery can bring the success rate of pregnancies from 50-55 percent to around 60-70 percent.
Nearly 5 million babies have been born using in vitro fertilization since the birth of world's first test-tube baby in 1978.
In recent years, new-generation sequencing has been widely used in stem cell transplant and metastatic tumor cells, mainly associated with the improvements of human health, according to BGI.
“The new-generation sequencing method shows significant accuracy enhancement over other existing screening techniques in identifying abnormalities in embryos, which allows doctors to only implant a healthy lab-fertilized egg in the womb,” said Lu Guangxiu, president of Reproductive and Genetic Hospital of Citic-Xiangya, which cooperated with BGI.
According to BGI, Citic-Xiangya transferred sequenced embryos for 33 couples and has achieved 22 pregnancies since 2010. The success rate stood at 66.7 percent. So far, 17 healthy babies have been born.

New screens can pinpoint gene mutation
Updated: 2013-07-23 23:18 By Liu Zhihua ( China Daily)
chinadaily.com.cn
The Beijing Centers for Disease Control and Prevention has developed a new technique to scan for mutations in the gene p53 to detect malignant genetic changes in human body.
Early detection of gene mutations can allow doctors to direct people to take precautions to stop malignant tumor growth, or to receive cancer treatment early to increase their chances of survival.
The institution announced it will cooperate with Sinopharm International to promote the technology nationwide.
P53 is one of the genes that suppress tumor formation, but when p53 itself mutates, the chance of a tumor formation will increase 50 to 90 percent.
Since the gene was discovered in the 1980s, scientists have been developing technologies to identify mutations in the gene and cancers related to those mutations.
In recent years, scanning of p53 has been used in some top hospitals in China to supervise the tumor growth in patients who undergo chemotherapy and radiotherapy.
However, this is the first time that the scanning of p53 is to be used on healthy people, according to Zhang Jie, the head researcher of the p53 scanning program with the institution.
The scanning services for cancer patients are usually very detailed and are very expensive, costing at least 10,000 yuan ($1,630) each time, Zhang said at a gene scanning technologies forum held by Health Times.
"Our technology is improved, and much simpler. It costs only about 1,000 yuan, and can be applied among common people as a body check choice."
If there is a mutation at a certain position of p53, there is a 50 to 90 percent chance there is, or will soon be, related tumors and a closer checkup will be required, Zhang says.
With only three drops of blood, the test can identify nearly all the important p53 mutations as an indication of the likelihood of related cancers, including liver cancer and breast cancer, Zhang adds.
However, some experts, including Du Bing, deputy director with Beijing Health Management Association, emphasize that the scanning can only exclude the possibility of some cancers, not of all cancers.
Du says the formation of a cancer is very complicated and prolonged.
Even if the test suggests there is no mutation at a certain time, there is no guarantee there will be no genetic mutation in future, or that those tested will definitely not have cancer, Du adds.

So @jhungary , you're a bouncer, a barman, an entrepreneur, a cavalry soldier, a womanizer, a citizen of the world with more nationalities than the hair on McCain's scalp & now you're a Telecom Engineer or a Specialist as well !
I'm thinking of using my connections & having you sent to Pakistan so that you can work as my Right-Hand Man as I take over 'My Country & build it in my Image' !
And yes the perks that come with that include - A Personal Harem full of the most exotic belly dancers that the world has ever produced !
But No Alcohol or Pork & if you're caught with either - You might go through a painful process for you but delightful & entertaining for the rest of us that sees you becoming the eunuch guarding the same Harem you used to Party in before !
lol.........I was a security guard in a mall, I never worked as a bouncer and I am allergic to high concentration alcohol so I will never be a bartender, I do own my business some time along the line but it have been largely forgotten and neglected
, I was a cavalrymen but not very good at it, and I could say I used to enjoy female company more than now that I am married 
I cannot say in clear conscience that I am anything Telco or infrastructure. I have an interest in Computer Science, if I was not asked to change my major to suit my ROTC duty, I would have gone for computer Science rather than international politic.

Scientists Use Asparagus To Fight Desertification In North China
BERNAMA - Scientists Use Asparagus To Fight Desertification In North China
also reporting and foto credit: bbc: China: Asparagus 'could hold back the desert'
TAIYUAN, July 25 (Bernama) -- Scientists have used asparagus in a successful experiment to curb desertification in north China, Xinhua news agency reported.
The popular vegetable in Chinese cuisine has been found to be suitable for use as a windbreak in a desert-control project in Youyu County in north China's Shanxi Province, researchers said.
"Asparagus can grow between 1.3 and 1.5 metres and reduce wind speed by 20 to 30 percent," said Mao Liping, a vegetable expert at the Shanxi Provincial Academy of Agricultural Sciences.
The project began in 2010 when scientists started looking for plants that could be used to contain sand in north and west China, which have long been plagued by desertification.
Asparagus was chosen for its strong resistance to drought and cold and its ability to grow in barren soil. Youyu County was chosen as the site of the project due to its harsh natural conditions.
"Youyu has worse conditions than deserts in Inner Mongolia and northeast China's Heilongjiang Province. If the crop can survive here, it can survive in those places as well," Mao said.
Mao said the farm where the crop is grown yields 20 tonnes of asparagus annually.
Researchers hope the crop can be used to increase incomes for farmers in impoverished desert areas.

芦笋治沙技术向“红色沙漠”宣战
http://www.biosino.org/news/200011/00111614.htm
新华网南昌11月16日 （2000) 电（记者李兴文）在沙化严重的南昌赣江古河道种植芦笋，既防风固沙，又产生了可观的经济效益，江西省生物工程博士陈光宇的这一成果最近纳入欧共体与中国的合作项目。专家指出，芦笋治沙技术为我国治理“红色沙漠”展现了新的前景。
赣江古河道两岸沙丘连绵，被 称为“红色沙漠”。南昌市域赣江古河道沙漠化地有十余万亩，占江西省沙化地的16%，是国家沙化地治理的重点地区之一。近年，这块“红色沙漠”正向南昌市逼近，尤其是在冬春两季。
过去治沙主要采取种植湿地松、刺槐等植树造林的方法，投入了大量的人力物力，但成活率不高，经济效益差，以致“年年种树年年死，春天过后成枯枝”。
芦笋耐旱，根须深扎，适宜于沙地栽培。而且芦笋有防癌抗癌作用，国际市场价格高，需求量也在不断增加，潜在经济价值明显。如果种植芦笋获得成功，以此来开发治理江西50万亩荒沙滩，通过示范将技术传授给农民，与劳力结合，将会形成一个大产业。1997年，江西省农科院生物工程中心的陈光宇博士率先在这里研究应用这一治沙新技术。
在南昌县富山乡的赣江古河道，陈博士指导试种的150亩芦笋，如今透出一片新绿，亩产可达1000公斤，按每公斤10元计，年经济收入在万元以上。同时附近的生态条件也得到了明显改善。在周围农民中产生了良好的示范效应。
陈博士下一步准备将规模扩大到2000亩以上，他的示范基地，得到欧共体治沙专家小组首肯。欧共体治沙组织当即决定投资100万元，为基地增添设备。（完）

Huawei and other Chinese telecom companies need not to enter the American market。There is enough business in the emerging and developing economies where the Chinese concerns can beat the sh1t out of their American competitors。
In the same time，American telecom firms such as CISCO should be excluded from the Chinese market for competitive and security reasons。In the end，the size of the Chinese market will be several times that of the US。
Ethiopia signs $1.6 bln mobile network deal with China's Huawei
Aaron Maasho July 26, 2013
ADDIS ABABA (Reuters) - Ethiopia on Thursday signed a $700 million agreement with China's Huawei Technologies Co Ltd to expand mobile phone infrastructure and introduce high-speed 4G broadband network in the capital Addis Ababa and 3G service throughout the country.
Huawei, the world's second largest telecom equipment maker, has been involved in developing phone and internet services in the Horn of Africa country for several years.
Africa's rapidly expanding telecoms industry has come to symbolize its economic growth, with subscribers across the continent totalling almost 650 million last year, up from just 25 million in 2001, according to the World Bank.
Andualem Admassie, acting chief executive officer of state-run Ethio Telecom, and Jony Duon, his counterpart at the Chinese firm, signed the agreement that will double subscribers to 56 million.
"Although our target is 40 million, now including 3G it will 56 million by 2015. That would be the capacity," said Debretsion Gebremichael, Ethiopia's deputy prime minister and minister of communications and technology.
The agreement is half of a $1.6 billion project split between Huawei and ZTE, China's second-largest telecoms equipment maker. Both firms will finance the amount. Ethiopia will sign the other half of the agreement next week, Debretsion said.
Ethio Telecom is the only mobile operator in the country of more than 80 million people, one of the last remaining countries on the continent to maintain a state monopoly in telecoms.
Although lacking much of a telecoms industry, the government last year gave approval for private companies to provide value-added services - all services other than standard voice calls.
Ethiopia's ministry of communications and information technology says it has received applications from 218 firms to provide such services. South Africa's MTN Group, Africa's largest mobile phone company, has already been granted a licence.
The government has ruled out liberalising its telecom sector saying the six billion birr it generates each year is being spent on railway projects. Ethiopia plans to build 5,000 km of railway lines by 2020.

Tooth generated from stem cells: Chinese scientists
English.news.cn 2013-07-30 14:34:49
Xinhua | English.news.cn
Credit:bp.blogspot.com
BEIJING, July 30 (Xinhua) -- Chinese scientists have successfully grown tooth-like structures from induced pluripotent stem cells (iPS cells), the Chinese Academy of Sciences (CAS) said.
The structures were found to possess physical properties, such as elasticity and hardness, that are similar those found in regular human teeth, according to a statement issued by CAS on Tuesday.
The research efforts were led by Pei Duanqing, a researcher at the CAS's Guangzhou Institute of Biomedicine and Health.
A related paper has been published online in the journal Cell Regeneration.
The scientists differentiated iPS cells derived from human urine and then recombined them with dental mesenchymes isolated from mouse embryos, according to the statement.
The recombinant was later transplanted to mouse bodies and tooth-like structures were recovered within three weeks, it said.
The tooth-like structures have the same features as human teeth, including dental enamel, dentin, dental pulp and cementum, the statement said.
"There are currently some problems with the research, such as the use of mice cells, a low success rate and low enamel hardness, but these will be solved through further improvements," Pei said.
Pei said the research results demonstrated that the urine iPS technique can be used to regenerate patient-specific dental tissues or even teeth and may be further developed for drug screening or clinical regenerative therapies.
Like embryonic stem cells, iPS stem cells can develop into any cell in the human body.
Shinya Yamanaka, a professor at Kyoto University, was one of the winners of the 2012 Nobel Prize in physiology or medicine for developing an iPS cell harvesting technique that allows stem cells to be obtained from adult tissue instead of from embryos, thus avoiding the ethical and legal barriers that embryonic stem cells face

BEIJING, July 30 (Xinhua) -- Chinese scientists have successfully grown tooth-like structures from induced pluripotent stem cells (iPS cells), the Chinese Academy of Sciences (CAS) said.
The structures were found to possess physical properties, such as elasticity and hardness, that are similar those found in regular human teeth, according to a statement issued by CAS on Tuesday.
The research efforts were led by Pei Duanqing, a researcher at the CAS's Guangzhou Institute of Biomedicine and Health.

Potty Mouth: Chinese Researchers Make Teeth From Urine
July 30, 2013
A team of researchers from China’s Guangzhou Institutes of Biomedicine and Health have demonstrated human teeth can be generated by stem cells from a very interesting source: Urine. The Chinese team says they can also generate other solid organs and tissues from human waste.
It’s been observed before that stem cells are found in urine. Furthermore, when these stem cells are collected, scientists can coerce them to become induced pluripotent stem cells (iPSCs) which are capable of generating other types of cells. These cells can then be genetically molded and coaxed into other organs and tissues, including heart muscle cells and neurons.
Duanqing Pei and the rest of the team from Guangzhou Institutes of Biomedicine and Health now say they’ve developed a way to coerce these iPSCs into teeth-like structures. Though these collections have the essential components of human teeth, the final product isn’t quite as hard as the teeth humans are naturally born with. Their study is published this week in the open-access journal Cell Regeneration.
Just as it’s been observed in normal tooth development, the new system created by the Chinese team makes use of the interaction between the epithelial cells and mesenchymal cells. The former cells are responsible for producing the enamel which coats the teeth while the latter builds out the internal components inside the tooth. These include the cementum, dentin and pulp.
Pei and crew first gathered the stem cells from urine and mixed them with chemicals to encourage the epithelial cells to lay flat from the iPSCs. They then took these flat cells and mixed them with embryonic mesenchymal cells from mice. The final product was then transplanted into the mice.
Though the stem cells from urine were mixed with embryonic mouse cells and implanted into the rodents, structures began to grow which, according to the team, closely resembled human teeth. They claim they have a very similar makeup, but have only one-third the hardness of a typical human tooth.
Their method is also a bit inconsistent at the moment and is capable of reproducing human teeth only 30 percent of the time. The new method is still a breakthrough say the researchers, and they’re already working on ways to improve their system.
For instance, they claim they might better grow human teeth if they use human mesenchymal stem cells as opposed to mouse cells. The controversial nature of stem cell research, however, could make it difficult for the team to move forward in this regard. Additionally, Pei and team say they could continue modifying the tissue culture to grow a stronger tooth. In this instance, the bud of a tooth could be grown in the lab before being transplanted into a human jaw to finish its development.
Though this new system is a breakthrough in the field of regenerative cell growth, some say there are better places to be looking for the crucial iPSCs than urine.
“It is probably one of the worst sources, there are very few cells in the first place and the efficiency of turning them into stem cells is very low,” explains professor Chris Mason, a stem cell scientist with the University College London in an interview with BBC News.
“The big challenge here is the teeth have got a pulp with nerve and blood vessels which have to make sure they integrate to get permanent teeth.”

Only 130 dollars？WTF！
It is gonna be my 3rd smartphone。
Xiaomi unveils Red Rice smartphone in China: $130 for 720p and a quad-core CPU Mobile
By Steve Dent posted Jul 31st, 2013 at 11:59 AM
Xiaomi's talk about doubling smartphone sales over last year sounded a tad ambitious, but it turns out it had a secret weapon. The company just announced the Red Rice smartphone, a pretty decently spec'd model priced at a mere 799 yuan ($130). For that pittance, Chinese buyers will get quite a bit: a quad-core MediaTek CPU, 4.7-inch 720p screen (312 ppi) with Gorilla Glass 2, 1GB RAM, 4GB storage, China Mobile's TD-SCDMA 3G, dual-sim / dual standby capability, an 8-megapixel rear camera and Xiaomi's MIUI-flavored Android. Though it's lacking the WCDMA-3G used by other Chinese networks, China Mobile's 70 percent market share should give Xiaomi more than enough users to hit its targets, especially at that price.

After Rice（Mi）1、Mi2、Mi2S and Red Rice，MI3 is around the corner：
In just 2 years，Xiaomi has risen from nothing to a 10 billion dollar company（per the latest round of fund raising）。
Way to go！
