› Origins of Sun's swirling spicules discovered
For the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly. |

› Peroxisomal biogenesis disorder: New link to sugar metabolism
Peroxisomal biogenesis disorder, which has been linked only to lipid metabolism, is also associated with sugar metabolism. |

› Spinal cord injury: Using cortical targets to improve motor function
New research provides the first evidence that cortical targets could represent a novel therapeutic site for improving motor function in humans paralyzed by spinal cord injury. |
|
|
|
› Interventions to prevent cognitive decline, dementia
Cognitive training, blood pressure management for people with hypertension, and increased physical activity all show modest but inconclusive evidence that they can help prevent cognitive decline and dementia, but there is insufficient evidence to support a public health campaign encouraging their adoption, says a new report. |

› Flexible wearable electronics use body heat for energy
In a proof-of-concept study, engineers have designed a flexible thermoelectric energy harvester that has the potential to rival the effectiveness of existing power wearable electronic devices using body heat as the only source of energy. |

|
|
› Quantum thermometer or optical refrigerator?
In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. |

› How eggs got their shapes
The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery. Now, an international team of scientists took a quantitative approach to that question and found that adaptations for flight may have been critical drivers of egg-shape variation in birds. |

› Catalyst mimics the z-scheme of photosynthesis
A new study demonstrates a process with great potential for developing technologies for reducing CO2 levels. |

|
› Previously unknown pine marten diversity discovered
The elusive American pine marten, a little-studied member of the weasel family, might be more diverse than originally thought, according to new research. |
|
|
|
› How do genes get new jobs? Wasp venom offers new insights
A new study describes how four closely related species of parasitic wasps change their venoms rapidly in order to adapt to new hosts, and proposes that co-option of single copy genes may be a common but relatively understudied mechanism of evolution for new gene functions, particularly under conditions of rapid evolutionary change. |

› First Chikungunya-infected Aedes aegypti mosquitoes found in Brazil
While more than 13,000 cases of Chikungunya viral disease were reported in Brazil in 2015, scientists had never before detected the virus in a captured mosquito in this country. Now, researchers have identified a mosquito -- caught in the Brazilian city of Aracaju -- that's naturally infected with the East-Central-South-African (ECSA) genotype of Chikungunya. |

› Simulated honeybees can use simple brain circuits for complex learning
Honeybees may not need key brain structures known as mushroom bodies in order to learn complex associations between odors and rewards, according to new research. |
