Science Glance
Stem cells made from skin have become "grandparents" after generations of life were created in experiments by scientists in Japan.
The cells were used to create eggs, which were fertilised to produce baby mice. These later had their own babies. If the technique could be adapted for people, it could help infertile couples have children and even allow women to overcome the menopause.

Japanese scientists claim first synthesis of element 113
If confirmed, the feat would mark the first time Japanese researchers have been first to synthesize an element of the periodic table. It would also be the first time an Asian research team has had the honor of naming an element.
Faint galaxy sheds light on universe's early years
The Hubble Space Telescope has detected light from a small galaxy emitted about 500 million years after the big bang, an early era of the universe about which scientists know relatively little.
Last year, astronomers used Hubble to find another galaxy at a redshift of about 10, suggesting it was formed 480 million years after the big bang. But the help from gravity's magnifying glass allowed the CLASH team to learn more detail about MACS 1149-JD, Zheng said.
Atomic bond types discernible in single-molecule images
A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned.
The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings.
The new work opens up the prospect of studying imperfections in the "wonder material" graphene or plotting where electrons go during chemical reactions.
ALICE scientists enter primeval plasma wonderland
Scientists at CERN have smashed together various particles for the first time, moving closer to learning what was in the super-hot plasma wonderland that formed right after the primeval Big Bang, the European physics research centre said on Thursday.
The announcement followed another boost for physicists at CERN near Geneva with the effective endorsement by independent experts in a key journal of their claimed discovery of a new particle, the Higgs Boson.
Curiosity could pollute any water found on Mars
For all the hopes NASA has pinned on the rover it deposited on Mars last month, one wish has gone unspoken: Please don't find water.
Scientists don't believe they will. They chose the cold, dry equatorial landing site in Mars' Gale Crater for its geology, not its prospects for harboring water or ice, which exist elsewhere on the planet.
Arctic melt could affect weather long-term
This summer's record-breaking arctic melt is accelerating, with sea ice becoming significantly thinner and more vulnerable, Norwegian researchers say. Scientists with the Norwegian Polar Institute said the annual thaw of the region's floating ice reached the lowest level since satellite monitoring began more than 30 years ago."It is a greater change than we could even imagine 20 years ago, even 10 years ago," the institute's international director, Kim Holmen, told the BBC. "And it has taken us by surprise and we must adjust our understanding of the system and we must adjust our science and we must adjust our feelings for the nature around us."
