| Dramatic growth of grafted stem cells in rat spinal cord Posted: 07 Aug 2014 09:17 AM PDT Scientists have reported that neurons derived from human induced pluripotent stem cells and grafted into rats after a spinal cord injury produced cells with 10s of thousands of axons extending virtually the entire length of the animals' central nervous system. |
| Astronomers find stream of gas, 2.6 million light years long Posted: 07 Aug 2014 07:50 AM PDT Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light years long between galaxies 500 million light years away. The stream of atomic hydrogen gas is the largest known, a million light years longer than a gas tail found in the Virgo Cluster by another Arecibo project a few years ago. |
| Acute psychological stress promotes skin healing in mice Posted: 07 Aug 2014 07:43 AM PDT Brief, acute psychological stress promoted healing in mouse models of three different types of skin irritations, in a new study. Scientists found that healing was brought about by the anti-inflammatory effects of glucocorticoids -- steroid hormones -- produced by the adrenal glands in response to stress. |
| Synthesis of structurally pure carbon nanotubes using molecular seeds Posted: 07 Aug 2014 07:43 AM PDT For the first time, researchers have succeeded in "growing" single-wall carbon nanotubes (CNT) with a single predefined structure -- and hence with identical electronic properties. And here is how they pulled it off: the CNTs "assembled themselves", as it were, out of tailor-made organic precursor molecules on a platinum surface. In future, CNTs of this kind may be used in ultra-sensitive light detectors and ultra-small transistors. |
| Girls feel they must 'play dumb' to please boys, study shows Posted: 05 Aug 2014 06:09 AM PDT Girls feel the need to play down their intelligence to not intimidate boys, concludes research by a sociologist. The research also found that boys aged 14 believed that girls their age should be less intelligent. "There are very strong pressures in society that dictate what is a proper man and a proper woman," argues the researcher. "Young people try to adapt their behavior according to these pressures to fit into society. One of the pressures is that ... being in a relationship with a woman who is more intelligent will undermine (males') masculinity." |
