| Posted: 23 Jun 2016 09:30 AM PDT When you're a firefly, finding "the one" can change the world. Literally. A new study demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of species -- thereby impacting global diversity. |
| New research uncovers why an increase in probability feels riskier than a decrease Posted: 23 Jun 2016 08:57 AM PDT New research uncovers why an increase in probability feels riskier than a decrease. The research falls under the realm of subjective probability, also known as likelihood or risk. While past research has looked at how people interpret single estimates of the probability for a future event, the focus of this research was on how estimates change over time. |
| Novel controller allows video gamer who lacks hands to compete with his feet Posted: 23 Jun 2016 08:23 AM PDT Engineering graduate students, one of whom lost his hands to meningitis, design and build a foot-activated video game controller. |
| Doubled sensitivity could allow gravitational wave detectors to reach deeper into space Posted: 23 Jun 2016 08:22 AM PDT Researchers report on improvements to what is called a squeezed vacuum source. Although not part of the original Advanced LIGO design, injecting the new squeezed vacuum source into the LIGO detector could help double its sensitivity. This would allow detection of gravitational waves that are far weaker or that originate from farther away than is possible now. |
| To tool or not to tool? Clever cockatoos make economic decisions about tool use Posted: 23 Jun 2016 07:09 AM PDT Cognitive biologists studied tool-related decisionmaking in an Indonesian cockatoo. They found that the animals seemed to carefully ponder about their choices: while doing so the animals scrutinized details such as differences in quality between the two food rewards, but also the functionality of the available tool as means to obtain the out-of reach food in the situation at hand. |
| In worldwide chemotaxis competition, researchers race cell lines to the finish line Posted: 22 Jun 2016 11:46 AM PDT Neutrophil-like cells must balance speed against chemotactic accuracy to win a chemotaxis maze race in the inaugural Dicty World Races, a worldwide competition. |
