| Winning a competition predicts future dishonest behavior, say researchers Posted: 03 Feb 2016 10:48 AM PST 'These findings suggest that the way in which people measure success affects their honesty. When success is measured by social comparison, as is the case when winning a competition, dishonesty increases,' Schurr explains. 'When success does not involve social comparison, as is the case when meeting a set goal, defined standard or recalling a personal achievement, dishonesty decreases.' |
| Researchers try to determine the cause of female red flour beetle promiscuity Posted: 03 Feb 2016 10:48 AM PST New research focused on four possibilities that may explain why beetles are so promiscuous: that mating benefits the female beetles by providing them with moisture; with nutrients in the ejaculate; with proteins that support egg laying; or with additional sperm. The findings led scientists to conclude that it was the need for additional moisture that fed the beetles' drive to mate so frequently -- even to the point where they would sometimes coerce a reluctant male. |

| 'Architect' aquatic insects build perfect shelters out of tiny stones and they balance their two halves as a survival strategy Posted: 28 Jan 2016 05:14 AM PST Larvae of caddisfly, aquatic insects of the order Trichoptera, using substrate particles, build tiny tubes where they protect their fragile bodies and carry out the metamorphosis which will transform them in adults. Researchers unveil a curious secret of Nature, unknown until now. When the time for pupation comes, larvae modify the architecture of their shelters, balancing their two halves by means of adding weight to both ends. The goal is that the tubes in which they stay captive until pupation can rest horizontally on the shallow banks of the streams, given that, in case of staying in vertical position, the probability of being exposed to the air would be too high and they could die. |
