Self-repair gene therapy promise  - BBC  Gene therapy experts say they have found a way to persuade cells to repair themselves. Instead of replacing a faulty gene, the new approach harnesses the cells' own correctional mechanisms. German researchers showed a drug could influence the way a gene behaved in patients with a debilitating genetic condition: spinal muscular atrophy (SMA). In patients with SMA the survival motor neuron gene (SMN1) is deleted, but they all carry a copy gene (SMN2). However, this only produces about 10% of the correct protein which is insufficient to prevent the diseases.         
Meteorites Discovered To Carry Interstellar Carbon - Science Daily  Left:  These tiny particles, from carbonaceous chondrite meteorites, are just a few millionths of a meter wide and have different proportions of nitrogen (N) and hydrogen (H and D) isotopes. These isotopes are chemically bonded to meteoritic organic matter and can reveal a lot about what happened to the meteorite as it made its way through the solar system over billions of years. The two images show the regions with high levels of 15N and heavy hydrogen (deuterium or D)-indications that the associated carbon is very old and originated from interstellar matter or the outer regions of the solar system. (Image courtesy Henner Busemann  "The tell-tale signs are lots of deuterium and 15N chemically bonded to carbon," commented co-author Larry Nittler.    

Ancient die-off blamed on climate, not humans - MSNBC  Failure to adapt to a drastically changing climate, and not overkill by humans or disease, most likely lead to the extinction of mammoths, wild horses, and other large mammals after the last Ice Age, a new study suggests. But this fresh take on an old argument might not be the final word. Like the end of the dinosaurs, the topic of large mammal extinctions is a hot one. While the new results might be true of the far North, some researchers still believe over-hunting contributed to the demise of the beasts across the rest of the continent. It's generally accepted that humans first entered North America from Siberia around 12,000 years ago. Since mammoths and wild horses became extinct roughly 11,500 and 12,500 years ago, some scientists have figured that hungry humans might have hunted them into oblivion.
