› How stress can curb the desire to eat in an animal model
Eating disorder researchers have discovered a neurocircuit in mice that, when activated, increased their stress levels while decreasing their desire to eat. |

› Humans migrated to Mongolia much earlier than previously believed
Stone tools uncovered in Mongolia by an international team of archaeologists indicate that modern humans traveled across the Eurasian steppe about 45,000 years ago. |

› Nylon as a building block for transparent electronic devices?
Scientists have solved a four decade long challenge of producing very thin nylon films that can be used for instance in electronic memory components. The thin nylon films are several 100 times thinner than human hair and could thus be attractive for applications in bendable electronic devices or for electronics in clothing. |

› Physiological mechanisms leading to enterovirus opening revealed
Enteroviruses are one of the most common human pathogens leading to high number of acute and chronic infections worldwide. The physiological events leading to successful enterovirus infection are still poorly understood. Researchers have found significant new information concerning the role of Albumin and ions in host cell vesicles that promote genome release and efficient infection. |

› Discovery of anti-opioid pathway offers new route to designing safer pain medications
A team has discovered a biological system that manages cells' response to opioid drug exposure. The unexpected discovery offers new ideas for improving the safety of the one of the most effective, and most abused, group of pain medications. |

› From the tiny testes of flies, new insight into how genes arise
A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences -- and a better understanding of how evolution moves forward. |

› Children with mild asthma can use inhalers as needed, study suggests
A new study supports evidence that children with mild asthma can effectively manage the condition by using their two inhalers -- one a steroid and the other a bronchodilator -- when symptoms occur. This is in contrast to the traditional method of using the steroid daily, regardless of symptoms, and the bronchodilator when symptoms occur. The as-needed use of both inhalers is just as effective for mild asthma as the traditional protocol, according to the investigators. |

› Researchers refine guidelines for pediatric brain injuries
There are no guidelines on whether a noninvasive method of measuring carbon dioxide from patients' exhalations, known as end-tidal capnography, is as effective as drawing blood through a child's artery. This study found that measuring the carbon dioxide level through an artery is still the most accurate diagnostic for pediatric brain trauma. |

› Cannabis-related poison control calls for Massachusetts kids doubled after medical pot legalized
After medical marijuana became legal in Massachusetts, cannabis-related poison control calls involving the commonwealth's children and teenagers doubled, according to a public health investigation. |

› Neuronal mechanism that is central to human free recall identified
Recently Weizmann Institute scientists succeeded in recording these rapid bursts of activity -- called 'hippocampal ripples' -- in the human brain, and they were able to demonstrate their importance as a neuronal mechanism underlying the engraving of new memories and their subsequent recall. |

› Researcher decodes the brain to help patients with mental illnesses
Approximately 1 in 5 adults in the United States experience mental illness in a given year. Severe mental illnesses cause the brain to have trouble dealing with cognitively effortful states, like focusing attention over long periods of time, discriminating between two things that are difficult to tell apart, and responding quickly to information that is coming in fast. |
