Abstract: The "Magnificent Seven" (M7) are a group of radio-quiet Isolated Neutron Stars (INSs) discovered in the soft X-rays through their purely thermal surface emission. Owing to the large inferred magnetic fields ($B\approx 10^{13}$ G), radiation from these sources is expected to be substantially polarised, independently on the mechanism actually responsible for the thermal emission.
Hydrothermal deposits on Mars may provide the best opportunity to find Martian biosignatures. Ruff and Farmer report that silica structures created by biotic and abiotic process in hot springs at El Tatio, Chile resemble those found in Gusev crater, thus making it an ideal location for future missions.
A light-bulb moment? Plants seem to pipe sunlight directly down into underground roots to help them grow. Light receptors in stems, leaves and flowers have long been known to regulate plant growth. Roots also have these receptors, but it has been unclear how they sense light deep in dark soil.
A frog study provides the strongest evidence yet that a father's lifestyle may affect the next generation, via chemical tags that change gene activity SPERM pass on more than just their DNA. Chemical switches attached to the genomes of sperm - known as epigenetic tags - have been shown to alter the next generation for the first time.
Perhaps when you think of bacterial communities you think of a flask full of rapidly dividing E. coli. But in non-lab conditions, bacteria grow in complex, heterogeneous communities composed of diverse microscopic organisms. In these communities, bacteria need a means to communicate with their kin, and they do this through a language known as quorum sensing (QS), where bugs secrete and detect factors that tell them whether they're surrounded by kin (and if so, how many there are).
http://www.nature.com/news/cheap-solar-cells-tempt-businesses-1.15986 Some of us would be interested in solar cells panel discussion during one of our weekly Science Coffee Meetings. We have experts on board of ACT, for example Joao, Katharina, Ricarda, we could also invite somebody outside from the ACT specialized in ESTEC. It could be very interesting and informative meeting.
Amazing things happen, development of 3D bioprinting technology opens a new era in restoring people after serious injuries. The test results seem to be very promising: printed cartilage, muscle and bone naturally connect with the body of the recipient (laboratory animals) without the risk of rejection, what will eliminate need to use immunosuppressive drugs and will significantly shorten the waiting period for a transplant! Animals rights' fighters will probably appreciate the fact that 3D bioprinting will replace laboratory animals for printed tissues in scientific research. This technology creates many new opportunities to transform our species to a new level of efficiency, hopefully it may not only become a contribution to the "I want to look like Brad Pitt" :)
