› High blood pressure linked to common heart valve disorder
For the first time, a strong link has been established between high blood pressure and the most common heart valve disorder in high-income countries. |

› Amazonian hunters deplete wildlife but don't empty forests
Conservationists can be 'cautiously optimistic' about the prospect of sustainable subsistence hunting by Amazonian communities, according to new research. The research team spent over a year working with 60 Amazonian communities and hiked for miles through trackless forests to deploy nearly 400 motion-activated camera traps -- in a bid to understand which species are depleted by hunting and where. |

› New examination of occupational licensing contradicts decades of research
From doctors to engineers to carpet layers to massage therapists, more than one in three Americans is required to hold a license to work in their occupation. Broad consensus among researchers holds that licensure creates wage premiums by establishing economic monopolies, but according to research, licensure does not limit competition nor does it increase wages. |

› How we determine who's to blame
Using eye-tracking technology, cognitive scientists have obtained the first direct evidence that people use a process called counterfactual simulation to imagine how a situation could have played out differently to assign responsibility for an outcome. |

› You would not ask a firefighter to perform open-heart surgery: Understanding 'collective intelligence'
The concept of 'collective intelligence' is simple -- it asserts that if a team performs well on one task, it will repeat that success on other projects, regardless of the scope or focus of the work. While it sounds good in theory, it doesn't work that way in reality, according to a researcher. |

› To keep Saturn's A ring contained, its moons stand united
For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring -- the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, astronomers now conclude that the teamwork of seven moons keeps this ring corralled. |

› Flexible 'skin' can help robots, prosthetics perform everyday tasks by sensing shear force
Engineers have developed a flexible sensor 'skin' that can be stretched over any part of a robot's body or prosthetic to accurately convey information about shear forces and vibration, which are critical to tasks ranging from cooking an egg to dismantling a bomb. |

› Cancer: New compound targets energy generation, thereby killing metastatic cells
Researchers have identified an enzyme that supports the survival and dissemination of metastatic cells, and developed a synthetic compound that targets the enzyme and kills the metastatic cells in mice with cancer. |

|
› Preservation for the (digital) ages
Researchers working with classicists and computer scientists have developed a method to preserve digital humanities databases. The preservation strategy allows scholars to re-launch a database application in a variety of environments -- from individual computers, to virtual machines, to future web servers -- without compromising its interactive features. |

› Study reshapes understanding of climate change's impact on early societies
A new study linking paleoclimatology -- the reconstruction of past global climates -- with historical analysis shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt. |

› Assessment shows metagenomics software has much room for improvement
A recent critical assessment of software tools represents a key step toward taming the 'Wild West' nature of the burgeoning field of metagenomics. |

› Scientists determine source of world's largest mud eruption
More than 11 years after the Lusi mud volcano first erupted on the Indonesian island of Java, researchers may have figured out why the mudflows haven't stopped: deep underground, Lusi is connected to a nearby volcanic system. |
