| Cichlid male nannies help out, especially if they've been sneaking Posted: 12 Oct 2011 03:56 PM PDT The highly social cichlid fish Neolamprologus pulcher displays cooperative breeding behavior, where non-parents contribute to rearing the offspring of the dominant breeding pair. Until now, it was assumed that male subordinates never gained paternity in the field. A new study reveals that some offspring from this domestic arrangement are actually fathered by subordinate members of the group, and when this happens these fish increase investment. |
| Posted: 12 Oct 2011 03:56 PM PDT New research finds that the lack of gestural information from both speaker and listener limits successful communication in virtual environments. |
| 'Cute' chimps in ads may harm the species' survival Posted: 12 Oct 2011 03:56 PM PDT Television ads featuring cute chimpanzees wearing human clothes are likely to distort the public's perception of the endangered animals and hinder conservation efforts, according to researchers. |
| Bacterial communication could affect Earth's climate, researchers discover Posted: 12 Oct 2011 12:17 PM PDT Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet's climate. |
| Self-replication process holds promise for production of new materials Posted: 12 Oct 2011 10:26 AM PDT Scientists have developed artificial structures that can self-replicate, a process that has the potential to yield new types of materials. |
| Posted: 12 Oct 2011 09:41 AM PDT Mathematicians have found that efficient feeding depends on how sugary a flower's nectar is, and whether an animal dips or sucks the nectar out. The researchers found that animals such as bees, which probe with their tongues, are "viscous dippers," and are most efficient when feeding on more sugary, or viscous, nectar. Suction feeders, such as birds and butterflies that draw nectar up through tubes, do their best when sucking up thinner, less sugary nectar. |
| Erasing history? Temporal cloaks adjust light's throttle to hide an event in time Posted: 12 Oct 2011 08:35 AM PDT Researchers have demonstrated for the first time that it's possible to cloak a singular event in time, by sending a beam of light down an optical fiber and through a pair of "time lenses", creating a burst of light. They were able to create a small gap in the flow of light concealing that a burst of light ever occurred. |
