British scientists have decoded the genetic sequence of wheat and this is the most significant breakthrough in agricultural science since the “Green Revolution.” This will help to grow faster and disease resistant crops which will help to meet the growing world food shortage. This will lead to greater food security and lower food prices. The farmers are expected to start producing higher yields of disease resistant crops within five years.
The researchers are now working to analyse the sequence to highlight natural genetic variation between wheat types, which will help significantly speed up current breeding programmes. Scientists also said that it would now be possible to identify genes which controlled important agricultural characteristics. Using the new DNA data they will be able to identify variation in gene networks involved in important agricultural traits such as disease resistance, drought tolerance and yield. A version of the data will be placed online so that farmers around the world could have immediate access to it. And it will help to accelerate the speed and accuracy of plant-breeding. While the genomes of rice and maize had already been sequenced, contributing to vastly improved breeding, wheat had so far proved harder to sequence because its genome was vast and highly complex. The new advance would help to produce crops that could thrive in challenging conditions at a time when the world was facing the prospect of food shortages.
Since the beginning stem cells have been under a lot of controversy. Stem cells are cells taken from human embryos just a few days after fertilisation. They can be turned into any of the body’s 200 mature cell types. They can also be used to study and treat diseases. The stem cells originate from the embryos and in order to acquire them the embryos have to be destroyed. The scientists wondered if they can create embryonic stem cells without the embryos. Scientists discovered that all they had to do was add four genes and a cell would reprogramme itself back to its original state when it was a stem cell, that reprogrammed cell seemed to be able to turn into many kinds of specialised cells in the body, an ability called pluripotent.
Researchers are trying to find out whether stem cells made by this reprogramming process are really the same as ones taken from embryos. But they found small differences and they need embryonic stem cells as a basis of comparison. So it is not very safe and effective to use these pluripotent cells. They tended to remember their tissue of origin, so researchers have to find ways to make the cells forget where they came from. So for all this study and comparison they need human embryonic stem cells.
Astronomers have discovered what they claim is a vast solar system of seven planets, orbiting a sun-like star, 127 light years away from Earth. An international team has confirmed the presence of the five planets and have tantalising evidence of two more in the planetary system which is believed to be the largest ever detected beyond the sun. The distance of the planets from their parent star follow a regular pattern, similar to that seen in our own solar system.
The astronomers have said “We have found what is most likely the system with the most planets yet discovered. This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets. Studies of planetary motions in the new system reveal complex gravitational interactions between the planets and give us insights into the long- term evolution of the system.”
The parent star known as HD 10180, lies in the southern constellation of Hydrus 127 light years away. The astronomers patiently studied it for six years using a planet finding instrument called the HARPS spectrograph.
The Chinese government is planning to pour billions of dollars to develop its air and rail network. This will help in enhancing the Army’s mobilisation to bring troops to remote areas. The completed project will include 8,000 km of railway lines and seven new airports, which will help in further widening of the asymmetry in border infrastructure between China and India.
The People’s Liberation Army (PLA) was close to finishing work on its plan to build a “digital great wall” along the borders in Tibet and Xinjiang. The digital wall is a network of fibre optics which will improve the PLA’s command control structure and communication. With the setting up of a new sentry post in Medog County, the infrastructure for the nationwide surveillance system had been put in place.
The new railway network will serve the dual purpose of enhancing troop mobility both to border areas and also within Xinjiang, to increase response times to any unrest. The travelling time will also be reduced by these new rail lines and airports. Much of the PLA’s focus is in increasing coordination and mobility between the country’s seven military regions, which was found to be lacking both during the 2008 unrest in Tibet and also in responding to the earthquake in Sichuan the same year.
Popeye is the hero for most of the children watching the Popeye shows. Children are so fascinated by the Popeye character that my son wanted to dress like Popeye for the fancy dress show in his school. Popeye Costumes are available in the stores with all the necessary accessories. There is no need to go in search of all the accessories needed, everything is available as a set. The costumes make the children look like the real character. My son was so fascinated by the dress that he refused to take off the dress even after the show and wanted to sleep in it. He also started eating spinach as he wanted to be strong like Popeye. He imagines himself to be Popeye and wants to save Olive. As the Popeye character is quiet harmless we let him live in his imaginary world as long as he is playing. He jumps from chairs and tables shouting like Popeye. He imagines the other characters and talks with them tirelessly. Children once if they like a character it is difficult to change them. So we let him live like Popeye and this will continue only till he finds another character that fascinates him.
Our life does not move without clocks. They are a part of our life. It is very difficult to know the time if there are no clocks. Clocks are an important article in every household and workplace. The antique clocks give an aesthetic look to the house and the office. I am very fond of grandfather clocks. The grandfather clocks like the Howard miller clocks add a new aesthetic look to the room. I have a collection of these howard miller grandfather clocks . My interest in these grandfather clocks started when I was a small boy. It came from my grandfather who had a very old clock with large pendulums and large keys to work them. As a small boy I used to watch him working on the clock and starting it with great interest. I was so fascinated by these clocks that it became my hobby to collect them. My friends used to make fun of my interest in these clocks. But they were also amazed by the collection I have, there are grandfather clocks, grandmother clocks, mantel clocks, table clocks and wall clocks. They call my room a museum as there are so many clocks as in a museum. My interest for these clocks makes me work on them tirelessly.
There are contradictory claims over the electronic voting machines, whether they are tamper-proof. Indian EVMs are fully tamper-proof when used under complete administrative safeguards prescribed by the ECI. But the EVMs are vulnerable to the so-called “dishonest display” attack whereby a microcontroller and a Bluetooth radio chip could be smuggled into the device using a genuine-looking display board. Through the use of these devices, which can be assembled at the cost of a few dollars, the attacker could then signal which candidates should receive stolen votes via a Bluetooth smart phone.
The EVM was also susceptible to attack through the use of an electronic chip, which attached directly to the EVM chips could rewrite the votes stored there. Not only could the votes be changed through this “electronic form of booth capture,” but the secrecy of election data could also be violated as the clip would allow the attacker to copy out the votes stored. But the uniqueness of the EVM was that it has no operating system, cannot be networked and no input was possible except from ballot unit of the machine.
Claims regarding EVM vulnerability were exaggerated, as the machine has new security features. These include dynamic code hopping with encryption, an interconnected cable that was crimped and moulded and a digital signature in the control unit.
Everybody wants that contour abs , but is it possible? It is possible only if we have the mind to exercise regularly. Stop making excuses and start exercising. We have to make the effort to improve our fitness levels and overall well being. We owe it to ourselves to be fit and healthy. We have to set exercise goals, boost our spirits and follow a healthy diet regimen.
Initially we may feel some discomfort or tiredness, but in the long run, a good fitness workout should make us feel invigorated and increase our endurance levels. If there is pain, slow down or stop, and if the pain persists, consult the physician. We don’t have to invest in equipment; invest in other resources like time and enthusiasm. Run or jog, or go for a brisk walk in the local park. We can also do yoga or pushups and crunches at home. Or we can exercise to our favourite fitness show on television all we need to do is follow the instructions. Many of us in our initial enthusiasm, join a gym, are very regular for the first few days and then, it gradually reduces to just a few sporadic sessions. Think of how much we can enjoy if we are healthy and fit. Beat the excuses and get into top form.
The study of accountancy is gaining popularity after the study of medicine and engineering. The cparequirements vary from state to state but the basic requirement is a bachelor’s degree and completion of a minimum number of hours in business and accounting. My niece decided to study for the CPA. It is very difficult to study by yourself for the exams. She found it easier to study when she joined a CPA preparatory class. She told me that she was able to understand the subject better when she was taught in the class. She was able to clear the entrance exams as she was doing her graduation. Then she worked in a accountancy firm where she got her experience in business and accounting. She cleared all the four sections of the CPT exam in the first attempt and we all know that it is very difficult to get through so easily. This was made possible by her teachers and the proper mentoring she got from them. There are very good courses available which help students to get through the tough exams easily. The net is an important source to know about these courses.
People have become aware of the cosmetic surgeries and this is mainly due to Cosmetic Surgery SEO . The internet has become the main source of knowledge for people to know about anything. I learnt about cosmetic surgery through the internet. I wanted to correct my teeth, which was out of place. I learnt about the doctor and the surgery through the internet. I was also able to get the views of patients who had already undergone the surgery. So I was able a get a feedback on the surgery. This search engine optimisation provides the patients with knowledge about the medical terms. The doctors also benefit from this as they get good response from the patient side. The SEO acts as a way of marketing for the hospital and the doctors. People come to know about the particular doctor through the search engines. There was a time when people had to enquire about hospitals and doctors with their friends and relatives. But now internet has made the task easy, people learn about the doctor and the treatment through the internet. Everything is just a click away. I was able to know about any subject through the internet. Anything from cooking, health tips and education can be learnt through the net.
