Japanese scientists Mice Cloned from Blood Drop

TOKYO - Japanese scientists successfully cloned a mouse from a drop of blood. The BBC reported that blood cells are taken from donor rats that will be used for cloning.

Teams from Riken Bioresource Center managed to make a female mouse can give birth to a normal life and youth. Scientists at institutions recently created nearly 600 genetic copy of a rat tail.

Mice cloned from a variety of sources including the donor cells are white blood cells are found in lymph nodes, bone marrow, and liver.

Japanese research group investigated whether blood circulation could be used for cloning. Their goal is to find an easy source of donor cells to clone mice.

The team led by Ogura Asuo taking blood from donor rats, isolating white blood cells, and uses the core for cloning experiments. They use the same technique to produce Dolly the sheep in Edinburg.

Their findings are included in a U.S. journal, Biology of Reproduction. They say the study shows for the first time can be cloned mice using peripheral blood cell nucleus.

78 Years Grandma's First Woman Cosmonaut Russia Ready to Mars

Moscow: Valentina Tereshkova established himself as a true cosmonaut. Russian women are ready to risk their lives and life on Earth for the sake of exploring Mars.

He expressed readiness to fly to Mars, although not going back to Earth. "I'm ready to go to Mars, although not back again. Only one way," Valentina said in a press conference at the cosmonaut training center in Moscow, Zvyozdny Gorodok, as published Phys.org, Friday (06/07/2013).

Cosmonauts 76 this year revealed that he was very loving Mars. He also called the Red Planet as his favorite planet. "Mars is my favorite planet," said Valentina.

Valentina admits mission to Mars is a very difficult thing. But he was still ready to execute the mission. Therefore, it is now a senior cosmonauts studied and analyzed about the possibility of flying to Mars. "As human beings, we still have many limitations. Yet this is a dream that should be achieved."

In the world of exploration of outer space, Valentina can not be underestimated. She is the first Russian woman who adventures into space. When flying out of the Earth, he was aged 26 years. He underwent his mission alone!

Amazingly, at that time, Valentina successful mission around the Earth as much as 48 times over 3 days. It is a proud achievement that makes it the confidence to go back into space.

As an appreciation for Valentina, Russia will celebrate the 50th anniversary of his historic mission into space on June 16. Name Valentina parallel to Yuri Gagarin, the first cosmonaut Russian man who went into space in 1961 ago.

Mars challenge

Journey from Earth to Mars is estimated only took 10 months, but there was no chance to go home.

Mars is not only facing an uncertain environment, no oxygen, no water, volunteers should also be prepared to deal with the condition of alienation, far away from the Earth and humanity. A condition that has never been encountered before in human history.

Some scientists have recently warned that sending people to the Red Planet could be dangerous. Because space travel the length of time the astronauts will be physically exhausting. From various studies the scientists discovered that the astronauts would lose half of their muscle strength in the mission to Mars.

For example, if astronauts to Mars between the ages of 30 to 50 years, when he returned to Earth, their muscle strength equivalent grandfathers 80 years of age.

In addition to the decline in physical fitness, astronauts also at risk of suffering from cancer as a result of damage to DNA from cosmic radiation, loss of bone density and mental stress due to isolation.
