WASHINGTON, Dec. 17 (Xinhua) -- The prestigious U.S. journal Science on Thursday chose a popular gene editing tool called CRISPR, which acts as a type
of molecular scissors able to selectively trim away unwanted genome parts and
replace it with new DNA stretches Nike Air Huarache Ultra Breathe Triple Black Outlet , as the 2015 Breakthrough of the Year.
It's an "unprecedented selection," the magazine's Managing News Editor John Travis said, given that the three-year-old technique appeared twice before among
Science's top 10 breakthroughs, in 2012 and 2013, and is the only one to
subsequently be elevated to the year's most groundbreaking scientific
achievement status.
The 2015 research advances using CRISPR that warranted this recognition have been on multiple fronts Cheap Womens Nike Air Huarache Run Ultra Br White , the journal said.
For example, researchers successfully used the tool to remove potentially harmful DNA sequences at 62 locations in the pig genome this year, overcoming a
major hurdle for humans to receive life-saving organ transplants from pigs.
Meanwhile, CRISPR was used to develop a long-sought gene drive, a system that allows the rapid transmission of an introduced gene throughout insect
populations faster than natural selection would permit. Researchers believed
such a system could help eliminate pests or the diseases they carry Womens Nike Air Huarache Ultra Sandals Pink On Sale , including creating malaria-blocking mosquitoes.
In April, Chinese researchers described their use of the technology to edit nonviable human embryos from a fertility clinic, in a world first that prompted
an international summit this month in Washington, D.C., to discuss human gene
editing.
There are already several existing gene editing methods Womens Nike Air Huarache Ultra Sandals Black Online , but the superior ability of CRISPR to deliver a gene to the right spot compared to its
competitors as well as its low cost and ease of use have allowed thousands of
labs, high school students, and "biohackers" alike to begin exploiting the new
technique, Science noted.
Bioethicist Hank Greely of the Stanford University compared CRISPR to the Model T Ford.
"The Model T wasn't the first car, but it changed the way we drive Mens Mizuno Wave Prophecy 2 Red Black Outlet , work, and live," Greely told the New Yorker. "CRISPR has made a difficult process cheap and reliable.
It's incredibly precise. But an important part of the history of molecular
biology is the history of editing genes."
"It's only slightly hyperbolic to say that if scientists can dream of a genetic manipulation, CRISPR can now make it happen," Travis said. "For better
or worse Clearance Mens Mizuno Wave Prophecy 2 Blue Orange , we all now live in CRISPR's world."
The nine other major scientific achievements of 2015 selected by Science included:
The voyage of the New Horizons spacecraft past Pluto in July;
The lymphatic system exists in the brain;
Engineering yeast to produce opiates;
Experimental confirmation of the correlation in the quantum state of two widely separated particles, a process called "entanglement";
Improvements in seismic imaging provided long-sought confirmation of the existence of mantle plumes, responsible for midplate volcanoes such as Hawaii;
The successful development of an Ebola vaccine;
Improving reproducibility for psychological science;
A new member of the human family was revealed from a hidden cave in South Africa harboring 1500 human fossils;
DNA sequencing of Kennewick Man, a 8,500-year-old skeleton found in 1996 in Washington state Wholesale Mens Mizuno Wave Rider 18 Black White Green , showed that today's Native Americans are direct descendants of Asian people who crossed the Bering
land bridge at least 15,000 years ago.
Car is the prestigious automobile and of course the costliest automobile. Dealers, manufacturers of car, and the people who are relocating find car
shipping as a difficult task. Due to invention in technology, auto transport has
now become the easier one. Auto transport facilities are the mother for
cars Womens Mizuno Wave Rider 18 Pink On Sale , because mother is a one who always thinks the safety of the child and cares for the child. Like wise auto
transport car shipping and auto transport companies which gives security and
cares for your car can be called as the mother for your cars.
FACILITIES OF AUTO TRANSPORT:
Auto transport means transporting of your automobiles from one place to another. The need for car shippers has been increased nowadays. The
facilities offered by the auto transport companies are
1. Ensure the safety of your vehicles
2. provide quick transporting
3. have insurance facilities
4. provides door drop facilities
5. provides you the facility of online car transport quotes
6. provides you free online speed, distance, time calculator for your convenience
7. Provides toll free and e-mail enquiry.
Your vehicle has been given utmost care and it reduces the work of car shipping.
PROCESS OF AUTO TRANSPORTATION:
Everyone have some doubts regarding the process of auto transporting; let?s see what the process
has followed in auto transportation. Auto transport companies may pick up your
car directly from you or they may ask you to drop your car in to their company,
after that they will finish the formal agreements with you. They have the trucks
which carry your vehicle to your destination and generally the truck which is
used to carry your vehicle has some more vehicles along with it. Generally they
don?t carry more than ten vehicles in a truck. An auto transport company also
offers you the facilities of owning the single truck for your car. Auto
transport companies call you and intimate the date of departure and arrival of
the vehicle.
USE OF INTERNET IN AUTO SHIPPING:
Do you don?t have any ideas regarding the auto transport companies, and then use the technological
invention internet to find the best companies. Search the auto shipping
companies through keywords; you get many detail. Cheap Jerseys China Cheap Jerseys From China Cheap Jerseys Cheap Jerseys China Cheap Jerseys From China Cheap Jerseys Free Shipping Cheap Jerseys From China Cheap Authentic Jerseys Cheap Replica Jerseys Cheap Nike NBA Jerseys ?
