| Hardy little space travelers could colonize Mars, space station research shows that Posted: 02 May 2014 09:02 AM PDT In the movies, humans often fear invaders from Mars. These days, scientists are more concerned about invaders to Mars, in the form of micro-organisms from Earth. Three recent scientific papers examined the risks of interplanetary exchange of organisms using research from the International Space Station.  |
| MERS coronavirus can be transmitted from camel to humans Posted: 02 May 2014 05:13 AM PDT The so-called Middle East respiratory syndrome (MERS) coronavirus was first found in June 2012 in a patient from Saudi Arabia, who suffered from severe pneumonia. Since this time, more than 300 persons have developed an infection, of whom about a third died. The fact that the Arabian camel is the origin of the infectious disease has been confirmed recently. The transmission pathways of the viruses, however, have not been clear until now.  |
| Length of exoplanet day measured for first time: Spin of Beta Pictoris b measured Posted: 30 Apr 2014 10:28 AM PDT Observations from ESO's Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours. This is much quicker than any planet in the planetary system — its equator is moving at almost 100,000 kilometers per hour. This new result extends the relation between mass and rotation seen in the solar system to exoplanets.  |
| Want a young child to 'help' or 'be a helper'? Choice of words matters Posted: 30 Apr 2014 05:31 AM PDT A new study has found that parent word choice matters when encouraging preschool-age children to help others. Children were significantly more likely to help an experimenter when he or she referred to help using nouns ('some children choose to be helpers') than when he or she referred to help using verbs ('some children choose to help'). The study looked at about 150 3- to 6- year-olds from a variety of ethnic and racial backgrounds.  |
