› Why modified carbon nanotubes can help the reproducibility problem
Scientists have conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells. |

› Deep learning method transforms shapes
Called LOGAN, the deep neural network, i.e., a machine of sorts, can learn to transform the shapes of two different objects, for example, a chair and a table, in a natural way, without seeing any paired transforms between the shapes. |

› A new discovery: How our memories stabilize while we sleep
Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation. |

› Potato as effective as carbohydrate gels for boosting athletic performance, study finds
Consuming potato puree during prolonged exercise works just as well as a commercial carbohydrate gel in sustaining blood glucose levels and boosting performance in trained athletes, scientists report. |

› Candidate Ebola vaccine still effective when highly diluted, macaque study finds
A single dose of a highly diluted VSV-Ebola virus (EBOV) vaccine -- approximately one-millionth of what is in the vaccine being used to help control the ongoing Ebola outbreak in the Democratic Republic of the Congo -- remains fully protective against disease in experimentally infected monkeys, according to scientists. The investigators completed the dosage study using cynomolgus macaques and an updated vaccine component to match the EBOV Makona strain that circulated in West Africa from 2014-16. |

› Cutting-edge neuroethics with ground-breaking neurotechnologies
Scientists are developing powerful new devices and technologies to monitor and regulate brain activity. To ensure NIH keeps pace with rapid technological development and help clinicians and researchers ethically fit these new tools into practice, a new article highlights potential issues around and offers recommendations about clinical research with both invasive and noninvasive neural devices. |

› Flexible, wearable supercapacitors based on porous nanocarbon nanocomposites
Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high energy density. A microfluidic technology was key for the preparation of the electrode material was a microfluidic technology, as shown in the journal Angewandte Chemie. |

› Genes linked to sex ratio and male fertility in mice
Researchers find genes that help maintain the 50-50 balance between male and female offspring in mice -- and that have major implications for male infertility. |

› Climate: Uncertainty in scientific predictions can help and harm credibility
The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness. |

› A new stable form of plutonium discovered
Scientists have found a new compound of plutonium with an unexpected, pentavalent oxidation state. This new phase of plutonium is solid and stable, and may be a transient phase in radioactive waste repositories. |

› All plastic waste could become new, high-quality plastic through advanced steam cracking
A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics - of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure. |
